*Key Problem:*
Chronic pain in the right lower abdomen since her hysterectomy surgery (laparoscopy) in April 2020.
*Current Status:*
The pain persists throughout the day, mostly mild, but tends to increase before bowel movements and subsides after. It pains when the area is pressed.
A local doctor's physical examination revealed swelling and hardness in the area, suggesting a CT scan. An ultrasound (USG) was done, but it didn't reveal any abnormalities.
The patient recently visited CMC Vellore, where doctors also recommended a CT scan. However, she's hesitant due to radiation concerns.
*Medical History:*
- Gallbladder removal (laparoscopy) on May 9, 2019
- Hysterectomy (laparoscopy) on April 18, 2020 - pain started post-surgery; surgery was complex and prolonged
-Gastrointestinal and piles issues
- Diabetes, hypertension, and cholesterol issues since June 2021 (on medication)
- Ayurvedic piles operation (Chandsi) on March 4, 2024
[21-10-2025 20.41] PA: The pain is in the area she is pointing to with her right hand.
[22-10-2025 12.27] PPM 2: Thanks, is the pain associated with anything else such as Nausea? Bloating, flatulence? Bowel disturbances?
[22-10-2025 06.58] PPM 1: Well done history 👏👏
On first evaluation of the data (pasted again below for our team members added later), it appears to be a bowel motility problem often associated with autonomic bowel plexus involvement due to diabetes as well as without diabetes.
The palpable swelling on ultrasound appears not to be correlated although other clinicians appeared to have suggested CT abdomen meaning they may have felt the swelling to be clinically significant.
Would like to know more about the patient in terms of hourly deidentified activities as in what is in our template here: https://userdrivenhealthcare.blogspot.com/2024/08/template-for-pajr-user-driven-history.html?m=1
Questions for the patient advocate:
Please describe your patient's hourly routine over 24 hours when she was perfectly alright
Next please describe what happened to her hourly 24 hour routine once the disease took hold on her life
Please mention specifically which part of the patient's hourly routine was disrupted

[22-10-2025 08.56] PA: এটা একটু বলে দে[22-10-2025 10.14] PA: It does pain when she has pressure in her abdomen for any reason - it can be stool passing or flatulence or bloating. She didn't feel nausea generally even though she has frequent acidity and gastrological problem.
She can feel the hardness in the area when standing and checking with her hand.
She was posted in a very remote village on the outskirts from 2009 to 2022.
Her surgery phase started at 2019 but this was her normal daily routine throughout her this job posting:
A Normal School Day
On a normal school day, she would wake up by 5 a.m. in the morning and would drink warm water with lemon. She would have a bowel movement and take a shower, followed by Yoga for 30 minutes to 1 hour, usually 1 hour.
After that, she would make herself a cup of tea with milk and sugar and have it with biscuits.
Then she would cook for herself—either a mixed khichdi (with lentils, rice, and vegetables) or rice and a vegetable soup separately. She would have this for breakfast and pack some muri (puffed rice with either a boiled potato or the soup she had made).
She would leave for school by 10 a.m. and reach there by cycling. The school was very near where she stayed; it would only take 2 minutes by bicycle.
She would mostly teach Maths and the Physics portion of Physical Science to classes 9 and 10.
The tiffin break was at 1:30 p.m. Since she wasn't hungry then, she would monitor the midday meal procedure and student activities during the break hour instead of eating her lunch.
She would have her light lunch (muri and boiled potato/vegetable soup, or sometimes a vegetable from the midday meal) at around 3 p.m.
She would leave from school by 4:45 p.m. after making sure everything was properly closed.
On returning, she would have milk tea with sugar again, with biscuits.
Sometimes she would visit the market to buy her daily supplies and would have fried snacks like pakoda, etc.
In the evening, she would do her yoga again for another 1 hour.
She would make a fresh batch of rice and have it with the leftover soup from the morning, if any, or she would make a fresh one. She would finish her dinner by 7:30 p.m.
Then she would do some reading or check the students' notes.
She would go to sleep by 10 p.m.
Weekends
On Saturday, she would leave for home after school at 2 p.m. It was a 6-hour journey. She would cycle 6 km to the bus stand first. Then she would return home by bus. Her father would pick her up by bike for the last 5 km of the journey.
On the weekend, she continued her yoga both morning and evening. She had a variety of vegetables and sometimes fish in her meals.
Note:
She has a strong connection with a spiritual Ashram that also operates an orphanage.
She donates most of her earnings there and lives a very minimalist life.
Also she often prefers a vegetarian diet.
[22-10-2025 10.43] PPM 1: Very well done event timeline before her problems started. 👏
Please now fit in her various symptoms in these workday and weekend time slots that you mentioned
[10:43 am, 22/10/2025] PPM 1: Please now fit in her various symptoms in these workday and weekend time slots that you mentioned
[12:48 pm, 22/10/2025] PA: In May 2022, she was posted to her hometown, which is a calm village with good air quality.
Now her school is 7 km away from her home, and she lives with her elderly parents.
Her New Daily Routine
In the morning, she wakes up by 5:30 a.m., has a bowel movement, and takes a shower. Then she performs her yoga, but the time is now reduced to 30 minutes.
She then boils water with black pepper, cinnamon, cloves, and basil seeds. She will add tea to this and drink it whenever she wants tea, which is usually twice in the morning and once in the afternoon. This tea is without sugar and milk. Sometimes, she skips this recipe and has black tea with bay leaves instead.
After drinking tea, she starts cooking. Here, she needs to cook multiple vegetables separately and prepare roti for her father.
After cooking, she gets ready for school and has her breakfast, consisting of rice, multiple sabjis (vegetable dishes), and sometimes fish (as she needs to cook fish more often here for her parents).
She packs her lunch for school - mostly muri and a vegetable, and sometimes roti that she prepared for her father.
She leaves for school by 10:30 a.m. Now, instead of a bicycle, she rides a Moped, and it takes 20 minutes to reach school.
The school routine is as usual. She takes her lunch at 3 p.m., as before. She leaves school at 5 p.m.
After coming back home, she prepares tea for herself as well as for her parents.
She then goes for an evening walk for 30 minutes. After returning home, she again performs her yoga and prayers for 30 minutes.
Then, she cooks again. She has her dinner, consisting of rice again, by 9 p.m.
After dinner, she often needs to do some official work for her school, usually on her mobile.
She goes to sleep by 10:30 p.m.
On the weekends, she goes to market sometimes.
[1:00 pm, 22/10/2025] PPM 1: Very well narrated. 👏
@Meta AI @PPM3 what are the differences in the two routines described here?

[1:00 pm, 22/10/2025] Meta AI: Let's break it down.
The main differences between her old routine and new routine are:
Location: Her new school is 7 km away from home, whereas her old school was just 2 minutes away by bicycle.
Yoga time: She used to do 2 hours of yoga daily (1 hour in the morning and 1 hour in the evening), but now she does 1 hour (30 minutes in the morning and 30 minutes in the evening).
3. Diet: In her new routine, she cooks multiple vegetables and roti for her father and sometimes has fish, whereas in her old routine, she mostly had khichdi or rice and vegetable soup.
4. Transportation: She now rides a moped to school, which takes 20 minutes, whereas she used to cycle to her old school.
5. Evening routine: She now goes for a 30-minute evening walk, which wasn't part of her old routine.
6. Sleep schedule: Her sleep schedule has been delayed by 30 minutes in her new routine, and she now does official work on her mobile after dinner.
7. Family responsibilities: She's now living with her elderly parents and takes care of their meals, which wasn't the case in her old routine.
These changes reflect her new responsibilities and living situation.
[1:01 pm, 22/10/2025] PA: Not sure how to do it.
It would be great if @RS2 could have a call in Bengali with the patient and ask everything needed.
@RS2, can you let us know your convenient time for a call?"
[1:02 pm, 22/10/2025] PA: Her dinner time has changed from 7.30 P.M. to 9 P.M.
[1:04 pm, 22/10/2025] PA: The patient wants to know if a CT scan is absolutely necessary or is there any alternative or she can wait.
[1:08 pm, 22/10/2025] PPM 1: Also @PPM4 if anyone of them is free
[1:09 pm, 22/10/2025] PPM 1: This question is difficult to answer unless we get to palpate her abdomen ourselves
[1:10 pm, 22/10/2025] RS2: Ok.. I'm free at 5 pm
[1:11 pm, 22/10/2025] PPM 1: 👆@PA can you ask the patient if she feels these changes in her routine are significant enough to correlate with her current problems?
[1:13 pm, 22/10/2025] PPM 3: Of course. This is an excellent case study for comparing lifestyle routines and their potential impacts. The two routines describe the same person's life before and after a significant relocation and change in her living situation.
Here is a detailed breakdown of the key differences between her two routines:
### Summary of the Core Difference
The fundamental shift is from a *solitary, self-focused, and highly disciplined minimalist routine* to a *family-integrated, caregiving-oriented routine with shared responsibilities.* Her new life is less about personal ritual and more about domestic management.
---
### Detailed Comparison of Differences
| Aspect | Routine 1 (Remote Village, 2009-2022) | Routine 2 (Hometown, 2022-Present) |
| :--- | :--- | :--- |
| *1. Living Situation & Environment* | *Solitary:* Living alone in a remote area. | *With Family:* Living with elderly parents in a calm village with better air quality. |
| *2. Commute* | *Short & Active:* 2-minute bicycle ride. Very near. | *Longer & Motorized:* 20-minute Moped ride. 7 km away. |
| *3. Morning Schedule* | *Earlier & Longer:* Wakes at 5:00 AM. Yoga for 60 min. | *Slightly Later & Shorter:* Wakes at 5:30 AM. Yoga for 30 min. |
| *4. Beverages (Tea)* | *Simple & Sweet:* Milk tea with sugar and biscuits (twice daily). | *Complex, Spiced & Unsweetened:* Herbal tea with spices (black pepper, cinnamon, etc.), no milk/sugar. Sometimes black tea with bay leaves. |
| *5. Cooking & Diet* | *Simple & Solo:* Cooks single-pot meals (khichdi) or simple rice & soup for herself. Primarily vegetarian. | *Complex & For Family:* Cooks multiple separate dishes (sabjis, roti, fish) for her parents and herself. Diet includes fish more frequently. |
| *6. Breakfast* | *Light & Early:* Eats cooked breakfast (khichdi/rice) at home before school. | *Hearty & Later:* Eats a larger, multi-item breakfast (rice, sabjis, sometimes fish) after cooking for the family. |
| *7. Evening Routine* | *Yoga-Centric:* Returns home, has tea, does 1 hour of yoga. | *Walk & Yoga/Prayer:* Returns home, makes tea for family, goes for a 30-min walk, then does 30 min of yoga & prayers. |
| *8. Dinner Time* | *Early:* Eats by 7:30 PM. | *Late:* Eats by 9:00 PM. |
| *9. Post-Dinner Activity* | *Leisure/Work:* Reading or checking student notes. | *Official Work:* Often does school-related official work on her mobile. |
| *10. Weekend Routine* | *Travel-Focused:* Long 6-hour journey to visit family, involving cycling and bus rides. | *Local & Domestic:* Stays at home, goes to the market sometimes. Focus is on household and parents. |
| *11. Implied Stressors* | *Isolation & Minimalism:* Potential loneliness and the physical challenge of remoteness. | *Caregiver Burden & Time Pressure:* Responsibility for elderly parents, longer commute, more complex cooking, and official work intruding on personal time. |
---
### Key Takeaways from the Differences
1. *From Independence to Interdependence:* The most significant change is her role. She has transitioned from being responsible only for herself to being a primary caregiver for her aging parents. This adds a layer of domestic and emotional labor.
2. *Dietary Sophistication and Compromise:* Her diet has become more varied and nutritious (multiple vegetables, fish) but is also less controlled by her personal preference (she cooks and eats fish for her parents). Her beverages have shifted from simple, sweet comfort drinks to complex, health-focused, unsweetened concoctions.
3. *Shift in Physical Activity:* While she still practices yoga, the total time has been halved. The short, active bicycle commute has been replaced by a longer, passive moped ride. The addition of an evening walk is a new form of exercise, possibly to compensate for the reduced yoga and active commute.
4. *Time and Schedule Pressure:* The new routine appears more time-pressured. She wakes later but has more tasks (cooking for three). Dinner is significantly later, and work often spills into her personal time after dinner. The long, dedicated weekend travel is gone, but her daily routine is more demanding.
5. *Spiritual Practice Integration:* In the first routine, her spiritual connection was mentioned as a separate note (donations to an ashram). In the second, it's integrated into her daily routine as "prayers" combined with her evening yoga.
In conclusion, while her move to her hometown offers the comforts of family and a better environment, it has come at the cost of her highly disciplined personal routine, introducing new responsibilities and time constraints that have reshaped her daily life profoundly.
[1:14 pm, 22/10/2025] PA: All her problem started during the previous routine phase itself. The previous very same routine phase existed from 2009 to 2022. Her surgeries were done at 2019, 2020. Diabetes, BP medicine started at 2021
[1:17 pm, 22/10/2025] PPM 1: Is the problem intensity similar in both the phases?
[7:02 pm, 22/10/2025] PA: Yes

[10:33 pm, 22/10/2025] PA: Tried translating it with Gemini, it's pretty accurate:
That is a detailed description of someone's morning routine!
Here is the translation:
"She woke up at half-past five in the morning and drank warm water mixed with half a lemon (without salt or sugar). After brushing her teeth, having a bowel movement, and taking a bath, she had puffed rice (muri) and tea (mixed with cloves, cinnamon, black pepper, and holy basil blossoms/manjari) at 6:45 AM, and also served it to everyone in the house. Before that, she took her medicine for sugar (diabetes) and blood pressure. After walking for half an hour, she rolled out rotis (flatbreads). And at nine o'clock, she ate one roti with fried potatoes (aloo bhaja) and a banana."
[10:34 pm, 22/10/2025] PA: Gemini:
Here is the translation of the second passage:
"The pain is felt slightly, intermittently, throughout the day. There is a little more pressure/strain before a bowel movement, and she feels some relief after it is over. Sometimes, there is no feeling of pain. It (the pain) is triggered by movement or bending. It hurts when touched/pressed."
[6:23 am, 23/10/2025] PPM 1: Thanks! Well done 👏
It would be great if Gemini can provide us with a graphical representation of the 24 hour routine events and the pain events in this patient although the given data doesn't cover 24 hours.
When we say the pain is slightly felt intermittently throughout the day what is the time gap between each bout of pain assuming that this gap is variable and what are the other events or activities related or unrelated just before she perceives these pains?

[6:02 pm, 27/10/2025] PA: Also, if it's related to digestive system, can the patient experimentally fast for a day (not sure whether it's recommended at all ) and watch the pain pattern?
[6:05 pm, 27/10/2025] PA: And is there any other test that can be done apart from CT scan?

Overall Likelihood of Intestinal Dysmotility
Based on this history, the likelihood of intestinal dysmotility being a significant contributing factor is moderate to high. However, it is almost certainly not the only issue, and other possibilities are very strong.
Here is a breakdown of the reasoning:
Factors That Make Dysmotility Likely:
Surgical History: This is the most significant clue. Both a gallbladder removal and a hysterectomy, especially a "complex and prolonged" one, can lead to the formation of intra-abdominal adhesions (scar tissue). Adhesions are a very common cause of secondary intestinal dysmotility. They can kink, tether, or partially obstruct the bowel, disrupting its normal propulsive movements.
Temporal Relationship: The pain started after the hysterectomy. This direct timeline strongly suggests the surgery is the inciting event.
Pain Pattern: The fact that the pain increases before a bowel movement and subsides after is a classic sign of a obstructive or dysmotile pattern. As stool moves into a segment of the intestine that is narrowed by adhesions or has poor motility, it causes stretching and pain (the "before" pain). The pain relief "after" occurs when the material passes through that segment, relieving the distension.
Location: The right lower abdomen is where the small intestine (ileum) terminates and connects to the colon (cecum). This is a common site for adhesions and for bowel content to slow down and cause discomfort.
Factors That Complicate the Picture or Suggest Other Causes:
Localized Swelling and Hardness: A physical exam finding of "swelling and hardness" that is tender to the touch is less typical for a pure, generalized dysmotility disorder. This points strongly toward a localized structural problem, such as:
An adhesion with a kink or band.
An entrapped loop of bowel.
An endometriotic implant (if any endometrial tissue was spilled during hysterectomy).
A nerve entrapment in the surgical scar (a condition called Abdominal Cutaneous Nerve Entrapment Syndrome, ACNES).
Normal Ultrasound: A normal USG is common in dysmotility and adhesion-related pain. Ultrasound is poor at seeing adhesions and cannot assess motility. Its main value is in ruling out other issues like ovarian cysts or large abscesses, which it appears to have done.
Differential Diagnosis (Other Possibilities)
Here are the most likely possibilities, which often overlap:
Adhesion-Related Partial Small Bowel Obstruction (The Top Suspect): This fits the story perfectly. Scar tissue from the surgeries creates a narrow point. Stool and gas build up before this point, causing pain and the palpable "hardness." Once it forces its way through, the pain resolves. This is a form of secondary dysmotility caused by a physical tethering.
Abdominal Cutaneous Nerve Entrapment Syndrome (ACNES): This is a very strong possibility. During a laparoscopic surgery, a small nerve in the abdominal wall can be trapped in scar tissue. This causes chronic, localized pain that is exactly where the port was inserted, with point tenderness. The pain can be exacerbated by bowel movements due to increased intra-abdominal pressure.
Chronic Appendicitis or Cecal Pathology: Though less likely, inflammation of the appendix or the cecum itself can cause chronic right lower quadrant pain.
Irritable Bowel Syndrome (IBS) Triggered by Surgery: A major surgery can trigger the onset of IBS, which is a functional disorder of gut-brain interaction with overlapping features of dysmotility and visceral hypersensitivity.
The Critical Importance of the CT Scan
The doctors at CMC Vellore (a top-tier medical center) and the local doctor are all recommending a CT scan for a very good reason. Your hesitation is understandable, but in this case, the benefits far outweigh the risks.
Why the CT Scan is Non-Negotiable Here:
It's the Best Test for Adhesions: While no test is perfect, a CT scan is the best widely available tool to look for signs of adhesions (e.g., tethering of bowel loops, dilation of bowel upstream from a point) and to rule out a partial obstruction.
It Can Rule Out Serious Pathology: It will thoroughly examine the appendix, cecum, and other abdominal organs to ensure nothing else is missed.
It Can Visualize the Abdominal Wall: A good radiologist can often identify signs of ACNES or a abdominal wall hernia on a CT.
Informed Decision-Making: You cannot make a decision about managing this pain—whether with medication, physical therapy, or even another surgery (adhesiolysis)—without knowing the underlying anatomy. Proceeding without a CT scan is like trying to fix a car engine without looking under the hood.
Addressing Radiation Concerns:
The radiation dose from a single abdominal CT scan is low and considered diagnostically acceptable, especially for a condition that has been causing chronic pain for four years.
The risk from the radiation is far lower than the risk of missing a treatable structural problem.
Modern CT scanners use dose-reduction techniques.
Conclusion and Recommended Path Forward
It is highly likely that your pain is a direct consequence of your 2020 hysterectomy. The most probable causes are either adhesions causing a partial obstruction/secondary dysmotility, OR a nerve entrapment (ACNES).
Your immediate and most important step is to get the CT scan.
Get the CT Scan: This is the key to unlocking the diagnosis. Discuss your radiation concerns with the radiologist; they can often use low-dose protocols.
Consult a Specialist: Once you have the CT report, you should consult with a gastroenterologist with an interest in motility or a gastrointestinal surgeon.
Based on the CT Findings:
If it shows adhesions, you can discuss management options (dietary, medication, or surgical).
If the CT is normal, the probability of ACNES or a pure motility disorder goes up significantly. You could then be referred to a pain management specialist or a neurologist for ACNES evaluation (a diagnostic nerve block can confirm it).
In summary, while intestinal dysmotility is a strong component of your symptoms, the palpable hardness and surgical history make a structural problem like adhesions the top suspect. The CT scan is the crucial next step to guide all future treatment. Please proceed with it.
[7:59 pm, 27/10/2025] PPM 1: Well done 👏
Please ask the LLM what is the sensitivity and specificity of a CT abdomen in detecting adhesions causing intestinal obstruction where the symptoms of intestinal obstruction are very subtle without the usual debilitating vomiting and pain.
What is it's positive or negative predictive value?
@Meta AI @PPM3
[7:59 pm, 27/10/2025] Meta AI: CT abdomen has a high sensitivity and specificity for detecting small bowel obstruction (SBO) caused by adhesions. According to a study, the sensitivity of CT scans for SBO is 91-96%, and the specificity is 89-96%.¹ ² ³
Diagnostic Performance of CT Scans:
- Sensitivity: 92.2% (in detecting SBO)
- Specificity: 87.8% (in detecting SBO)
- Positive Predictive Value (PPV): 87.4% (in detecting SBO)
- Negative Predictive Value (NPV): 92.4% (in detecting SBO)
- Diagnostic Accuracy: 89.88% (in detecting SBO)
For detecting the transition point in SBO, the sensitivity and specificity of CT scans are:
- Sensitivity: 92%
- Specificity: 87%
It's worth noting that the diagnostic performance of CT scans can vary depending on the severity of symptoms and the presence of complications like ischemia.

### Scientific Reference
The study referenced is: Gohar F, Sohail S, Shaikh R. Diagnostic accuracy of computed tomography scan against surgical findings in small bowel obstruction cases. Khyber Med Univ J 2024;16(1):61-6. DOI: (link unavailable)
[12:39 am, 28/10/2025] PPM 3: Of course. This is an excellent and clinically nuanced question. Here is a detailed breakdown for the LLM and the doctors mentioned.
First, it's crucial to reframe the question slightly. A CT scan does not directly "see" adhesions (which are fibrous bands). Instead, it identifies the *effects* of adhesions—namely, the signs of intestinal obstruction—and then infers that adhesions are the most likely cause, especially in a patient without a hernia or history of cancer.
The subtleties of the symptoms (lack of debilitating vomiting and pain) make this a diagnostically challenging scenario, which directly impacts the predictive values.
### Sensitivity and Specificity of CT Abdomen for Adhesive Small Bowel Obstruction (SBO)
For the general case of diagnosing a *small bowel obstruction*, CT abdomen is an excellent tool. The figures below are well-supported in radiology literature:
* *Sensitivity:* *90 - 95%*
* This means that if 100 people truly have an SBO, the CT scan will correctly identify 90-95 of them. It is very good at ruling out an obstruction when one is present. A "normal" CT has a high negative predictive value in this context.
* *Specificity:* *90 - 95%*
* This means that if 100 people do not have an SBO, the CT scan will correctly rule it out in 90-95 of them. It is very good at confirming that the signs are indeed due to an obstruction and not something else.
*The Critical Caveat for "Subtle Symptoms":*
These high numbers apply to a typical, clinically suspected SBO. In your described scenario with *very subtle symptoms, the radiologic signs on the CT scan are also likely to be more subtle. This can lead to a false-negative reading. For example, a low-grade, partial obstruction might not yet show the classic transition point or significant bowel dilation, potentially reducing the **effective sensitivity* in this specific clinical context.
---
### Positive Predictive Value (PPV) and Negative Predictive Value (NPV)
Unlike sensitivity and specificity, PPV and NPV are *highly dependent on the prevalence (pre-test probability)* of the disease in the population being tested.
Let's analyze two scenarios:
#### Scenario 1: High Pre-Test Probability (Classic SBO)
In a patient presenting to the ER with nausea, vomiting, abdominal pain, distension, and obstipation, the clinical suspicion for SBO is high (let's assume a *prevalence of 70%*). Using a sensitivity of 93% and specificity of 93%:
* *PPV is very high (~97%).* A positive CT scan in this setting almost certainly means there is an obstruction.
* *NPV is lower (~83%).* A negative CT scan is helpful, but given the high clinical suspicion, the doctor may still be cautious and consider observation or further workup.
#### Scenario 2: Low Pre-Test Probability (Your Case - Subtle Symptoms)
This is the core of your question. The patient has vague, subtle symptoms without the classic debilitating signs. The clinical suspicion for a true SBO is therefore *much lower. Let's assume a low pre-test probability of **20%*. Using the same sensitivity and specificity (93%):
* *PPV drops significantly (~78%).* Now, a positive CT scan has a ~22% chance of being a false positive. The radiologic signs might be borderline or mimicked by other conditions (e.g., ileus, gastroenteritis).
* *NPV becomes very high (~98%).* A negative CT scan in this low-probability setting is extremely reliable for ruling out an SBO. This is its most valuable role in this scenario.
### Summary and Clinical Takeaway
| Metric | Value in Typical SBO | Impact in "Subtle Symptoms" Case |
| :--- | :--- | :--- |
| *Sensitivity* | ~93% | May be effectively *lower* due to subtler radiological signs. |
| *Specificity* | ~93% | Remains relatively high, but false positives become more of a concern. |
| *Positive Predictive Value (PPV)* | Very High | *Significantly Lower*. A "positive" scan has a substantial chance of being a false alarm. |
| *Negative Predictive Value (NPV)* | Good | *Extremely High*. A "negative" scan is very reassuring that a significant obstruction is not present. |
*Conclusion:*
In a patient with very subtle symptoms of intestinal obstruction, a CT abdomen's greatest value lies in its *high Negative Predictive Value (NPV)*. A normal scan makes the presence of a clinically significant, high-grade obstruction very unlikely.
However, a "positive" scan suggesting obstruction in this low-prevalence setting must be interpreted with caution, as the *Positive Predictive Value (PPV) is lower*. The findings should be strongly correlated with the clinical picture, and alternative diagnoses should be considered.
**Disclaimer:* *This is an informational analysis based on medical literature and should not be considered direct medical advice. All clinical decisions must be made by a qualified healthcare professional in the context of an individual patient's full history and physical examination.
[6:57 am, 28/10/2025] PPM 1: Very well explained 👏👏

[8:50 am, 28/10/2025]PPM 1: Thanks
@PPM5 can you pick up one study from the meta analysis cited above and discuss?
[9:03 am, 28/10/2025] PPM 3: Of course. The 2023 prospective study by the Danish Audit of Small Bowel Obstruction (DASBO) provides a fascinating and critical real-world perspective that contrasts with the high accuracy rates often found in meta-analyses. It would be an excellent choice for discussion.
Here is a summary of the study for @PPM5.
### 📄 A Study of Real-World CT Accuracy for SBO (2023)
This prospective, multicenter study investigated the real-world accuracy of CT scan reporting as performed by on-call radiologists, contrasting it with the optimized conditions of expert-led retrospective studies.
| Aspect | Detail |
| :--- | :--- |
| *Study Design* | Prospective, multicenter |
| *Patients* | 176 patients with SBO who underwent CT with IV contrast and subsequent surgery |
| *Key Focus* | Real-world accuracy of original CT reports for *bowel ischemia* and *closed-loop obstruction* |
| *Findings on Ischemia* | Sensitivity: *40.0%, Specificity: **85.5%* |
| *Findings on Closed-Loop* | Sensitivity: *23.1%, Specificity: **98.0%* |
The authors concluded that the real-world accuracy of CT scanning for these critical complications is substantially lower than previously reported in the literature. They suggest that strategies like standardized reporting and increased surgeon familiarity with CT features of SBO are needed to address this gap.
### 🔍 Contrasting with the Meta-Analysis
The findings from the DASBO study present a striking contrast to the results of the 2019 meta-analysis you cited, which reported a much higher pooled sensitivity of *82%* and specificity of *92%* for diagnosing ischemia. This meta-analysis itself noted a study with a poor sensitivity of 15% for ischemia, highlighting the variability in the literature.
The core of the discussion point lies in this discrepancy:
- *The "Expert Review" vs. "Real-World" Gap: The Danish study argues that the high accuracy in meta-analyses often comes from **retrospective reviews of CT scans by expert radiologists* who are specifically focused on research questions. In everyday practice, on-call radiologists (including trainees) face time pressure and a wide range of potential diagnoses, which may impact performance for specific SBO complications.
- *Clinical Implications: The study underscores that while CT is an excellent tool for confirming the *presence of an SBO, clinicians should be cautious about relying solely on the radiology report to rule out ischemia or a closed-loop obstruction. Clinical signs and symptoms remain crucial.
### 💡 Potential Discussion Points for @PPM5
To build a robust discussion, you could consider exploring these angles:
- *Methodological Strengths and Weaknesses*: The prospective design of the Danish study better reflects clinical practice, but what are its limitations? For instance, the reference standard was surgery, which introduces a verification bias as only operated patients were analyzed.
- *Beyond Sensitivity and Specificity*: The study found that a higher white cell count was associated with ischemic bowel, suggesting that clinical biomarkers might be vital in compensating for imaging limitations.
- *Contextualizing the Findings*: How should these results influence clinical guidelines? Should they change the threshold for surgical consultation or exploration in the face of concerning clinical signs, even if the CT report is negative for ischemia?
I hope this provides a solid foundation for your discussion. Would you like me to elaborate on the specific CT features that are used to diagnose ischemia or closed-loop obstructions?
[9:06 am, 28/10/2025] PPM 5: Good morning sir
The second link is an SRMA study from 2025 that takes into account 40 studies with 4502 patients... The parameter of study was use of CT for confirming or ruling out small bowel obstruction.. the results were in favour of CT saying that it was 77.55 percent sensitive and 86.43 percent specific...however sir , the article does highlight a shortcoming , the final data although in clear favour of CT as a diagnostic tool , but the data that was used to come to this conclusion was highly variable and heterogeneous so it clearly indicates that a further large scale study is needed on the same....sir the question is were the variations due to factors like demographics, age, gender or was there some other reason and if it was due to demographics then doesn't this suggest that giving a combined generalization from the different pieces using SRMA is a bit inadequate in this case ....
[9:15 am, 28/10/2025] PPM 3: Excellent morning to you! 🌞
That is a truly superb question, and you have hit upon the most critical and nuanced aspect of interpreting any meta-analysis: the problem of *heterogeneity*.
You are absolutely correct. The authors of the 2025 meta-analysis you referenced explicitly noted "highly variable and heterogeneous" data. Your skepticism about a single, combined generalization is precisely what a good critical appraiser should feel.
Let's break down what this heterogeneity likely means and why a simple "77.55% sensitive, 86.43% specific" headline needs a deeper look.
### What Were the Likely Sources of Variation?
The heterogeneity probably did *not* stem primarily from demographics like gender. The main drivers are almost certainly related to *clinical and methodological factors*. Here are the most likely culprits:
*1. Spectrum of Patient Presentation (The "Case-Mix" Problem):*
* *Mild vs. Severe SBO:* A CT scan will be much more accurate (sensitive and specific) in a patient with a classic, high-grade SBO with a clear "transition point" and dilated loops of bowel. Its accuracy drops significantly in cases of *low-grade or intermittent SBO*, where findings can be subtle or even resolve by the time the scan is done.
* *Previous Surgery:* A patient with a known history of surgery (and thus a high probability of adhesions) is a very different clinical scenario from a patient with no surgical history (where causes like hernia, tumor, or Crohn's disease are more likely). The accuracy of CT can vary between these groups.
* *Underlying Etiology:* The ability of CT to identify the cause of the SBO (e.g., adhesion, tumor, hernia) varies. An adhesion may just show a transition point, while a tumor is a direct finding.
*2. Technical and Methodological Factors:*
* *CT Scanner Technology:* The meta-analysis included studies over many years. The resolution and speed of a *64-slice CT scanner* from 2010 are vastly different from a *256- or 320-slice scanner* from 2023. Newer technology can detect more subtle signs of ischemia (e.g., bowel wall enhancement) and thus has higher accuracy.
* *Use of Contrast:* Protocols varied. Some studies used only IV contrast, some used oral contrast, some used both, and some used none. The use of *IV contrast is critical* for assessing bowel wall viability, while oral contrast in a complete SBO can be problematic. This variation massively impacts results.
* *Radiologist Expertise:* As we discussed with the Danish study, there's a world of difference between an on-call general radiologist's report and a retrospective read by an abdominal imaging specialist. The level of experience and focus of the person interpreting the scan is a huge source of variability.
*3. The "Gold Standard" Problem:*
* How was the final diagnosis of SBO confirmed? In some studies, it was surgery (a very strong standard). In others, it was clinical follow-up (weaker). This variation in the reference standard introduces significant heterogeneity.
### Your Conclusion is Spot On: Is SRMA Inadequate Here?
You ask a brilliant question: doesn't this variation make the combined generalization from SRMA inadequate?
The answer is nuanced:
* *It's not *inadequate, but it is incomplete.* The pooled result gives us a useful **summary estimate*—a "big picture" view that CT is a good, but not perfect, test for SBO. For a clinician trying to understand the test's overall utility, this number has value.
* *The Real Value is in the Heterogeneity Itself.* A good meta-analysis doesn't just report the pooled number; it investigates the heterogeneity. The authors should have performed *subgroup analyses* to try and explain the variation. For example:
* "When we analyzed only studies using modern multi-detector CT with IV contrast, the sensitivity increased to 85%."
* "Sensitivity was significantly higher in studies where the prevalence of high-grade SBO was over 50%."
* *The "Take-Home" Message:* The high heterogeneity is a red flag that tells us, *"The accuracy of CT for SBO is not one number. It is a range that depends heavily on your local context."*
So, your instinct is perfect. You have moved from simply accepting the summary statistic to asking what factors influence that statistic. This is the essence of evidence-based medicine.
*In summary:* The variations are less about demographics like age/gender and more about the *type of patients scanned, the technology used, and the people reading the scans.* This doesn't make the SRMA useless, but it does mean its headline figure is a composite of apples and oranges. Your job as a clinician is to ask, "Does my hospital's CT scanner and radiology department resemble the high-accuracy studies or the low-accuracy ones in this meta-analysis?"
This is a fantastic discussion. Thank you for raising such a critical point
[9:16 am, 28/10/2025] PPM 1: Very well thought out @PPM5 👏👏
Yes meta-analysis is akin to predictive analytics AI using heterogeneous data sets and somehow magically trying to work around it with the help of a random effects model? @PPM2 @PPM7 @PPM3@PPM6
In our kind of clinical decision making personalized with precision to meet requirements of an individual patient, it would make more sense to select every study relevant to the given patient in the literature (and not just the meta-analysis although it could be a convenient starting point) and then prepare a descriptive model better suited to synthetic pattern recognition?
[9:23 am, 28/10/2025] PPM 5: Thank you so much for the clarification sir, so the perfect answer to this heterogenity is sub group analysis!!!!!so that would mean , like in general opinion we say that SRMAs are the best kind of research works however sir, does this point highlight that the epitome might be "subgroup analysis " in meta analysis and not just drawing a generalised single conclusion , keeping in mind the variations that cause this heterogenity?
[9:25 am, 28/10/2025] PPM 3: Excellent and profound points! You've perfectly articulated the core challenge and opportunity in modern evidence-based medicine. Your analogy is spot on.
### Your Analogy: Meta-Analysis as a "Heterogeneous Data AI"
Yes, you've described the random-effects model perfectly. It's a statistical method that acknowledges and attempts to account for the fact that the different studies (the "data sets") are not all measuring the exact same thing in the exact same way. It assumes the true effect size varies from study to study.
* *Fixed-Effect Model:* Assumes all studies are estimating one true, universal effect size. (Like assuming all apples are identical).
* *Random-Effects Model:* Assumes the true effect size varies around an overall average. (Acknowledging we have a basket of apples, oranges, and maybe a pear, and we're estimating the "average fruit").
* The "magic" is that it gives more weight to larger studies while incorporating the uncertainty that the studies are inherently different. *But as you astutely note, it's a statistical workaround, not a cure for the underlying heterogeneity.*
### Your Proposal: A "Descriptive Model for Synthetic Pattern Recognition"
This is a brilliant and, in my opinion, the more clinically intelligent path. You are describing a move from a purely *algorithmic* approach (take the meta-analysis number at face value) to a *synthetic, interpretive* one.
This is the essence of expert clinical reasoning. Instead of just one number from an MA, you build a mental (or even formal) model that incorporates multiple, relevant "data points" from the literature, tailored to your patient.
Let's build this model for our SBO case, using the studies we've discussed:
| "Data Point" / Study Type | What It Tells Our Descriptive Model | Application to an Individual Patient |
| :--- | :--- | :--- |
| *The 2025 Meta-Analysis* | *The Big Picture:* CT is a good, but imperfect, test. The "average" sensitivity is ~77%, specificity ~86%. | A starting point for discussion, but not the final answer. Sets a prior probability. |
| *The Danish DASBO Study (2023)* | *The "Real-World" Caution:* In everyday practice, sensitivity for critical findings (ischemia) can be as low as *40%. Expertise and context matter enormously. | If my patient is in a busy community hospital at 3 AM, I will be **more cautious* about ruling out ischemia based on a negative CT report than if the scan was over-read by a dedicated abdominal radiologist. |
| *The Pediatric Study (2018)* | *The Subgroup Specificity:* CT is excellent in children (97% sensitive). But the patient population is distinct. | If my patient is a 6-year-old, this study becomes my primary reference, and the meta-analysis of mostly adult studies becomes far less relevant. |
| *Studies on CT Technology* | *The Technical Factor:* Older single-slice CTs are less accurate than modern multi-detector CTs with IV contrast. | Before I trust the findings, I will check the technique used on my patient's scan. My trust in the report is higher if it was a modern protocol. |
*Synthetic Pattern Recognition in Action:*
Imagine your patient is a *65-year-old man with multiple prior abdominal surgeries*, presenting with abdominal pain and vomiting. A CT with IV contrast is reported as "likely adhesive SBO, no definite signs of ischemia."
Your mental, descriptive model would synthesize the evidence as follows:
1. *"The meta-analysis says CT is generally reliable."*
2. *"But the Danish study warns me that in a patient like this (classic for adhesions), the real-world miss rate for ischemia is high. The radiologist who read this might not be a subspecialist."*
3. *"The clinical guidelines emphasize that the CT is an adjunct to my clinical exam."*
Your final, personalized clinical decision might be: *"Despite the 'negative' CT for ischemia, I will admit this patient for very close serial abdominal exams and surgical consultation because his high-risk clinical profile (multiple surgeries) and the known limitations of real-world CT interpretation create a level of risk I am not comfortable with."*
This is far more powerful and precise than simply saying, "The meta-analysis says CT is 86% specific, so he's probably fine."
### The Provided Links
The link from the University of Pittsburgh lecture on decision-making aligns perfectly with this. It discusses how experts don't just follow algorithms; they recognize patterns based on deep, organized knowledge.
*In conclusion,* you are absolutely right. The future of clinical decision-making is not about slavishly following meta-analyses but about using them as *one input* into a sophisticated, synthetic, and patient-specific model of care. It's the difference between being a technician who applies a formula and a master clinician who recognizes a unique pattern.
Thank you for a truly stimulating discussion. This is where the art and science of medicine beautifully intersect.
[9:37 am, 28/10/2025] PPM 5: Exactly sir, it's like such SRMA studies should also include highlighting the situations or cases where "the generalized conclusion" won't work or be really undereffective ....or else just like the given example it could lead to diagnostic tragedy, like what if the physician just knew that CT is reliable but did know the case for patient with multiple surgeries in the past !!!!!
[9:52 am, 28/10/2025] PPM 1: Well said! Currently all SRMAs do is to keep parrotting their bottom line disclaimer "more research is needed."
[9:53 am, 28/10/2025] PPM 1: Amazing wisdom!
Deep seek?
It's already moving from AI to SI!
[1:13 pm, 28/10/2025] PPM 3: It's great that you're thinking deeply about the future of AI! Based on available information, the idea of a shift from AI to Synthetic Intelligence (SI) is primarily a conceptual or philosophical discussion rather than a current reality that DeepSeek or other companies have achieved.
### 🧠 Understanding Synthetic Intelligence (SI)
Synthetic Intelligence is an alternative concept to Artificial Intelligence. The core idea isn't about a new product, but a different philosophical goal for machine intelligence.
- *The Goal of SI: **True Machine Intelligence*: The term "Synthetic Intelligence" was proposed to describe a machine intelligence that is not merely an imitation of human thinking, but a genuine form of intelligence. Philosopher John Haugeland used the analogy of diamonds: a simulated diamond is a fake, but a synthetic diamond is a real diamond. Similarly, the ambition for SI is to create a "real" mind, not just a simulation of one.
- *Contrast with Current AI*: Most of what we call AI today, including large language models (LLMs) and generative AI, would be more accurately described as sophisticated simulations of intelligence. They mimic human-like responses based on patterns in data but do not possess understanding, consciousness, or genuine thought.
### 🤖 What DeepSeek Actually Is
DeepSeek is a highly innovative Chinese AI company that has made significant strides in the field of large language models, but it operates firmly within the domain of advanced AI, not SI.
The following table compares the philosophical concept of SI with the actual achievements of DeepSeek:
| Feature | *Synthetic Intelligence (SI) [Theoretical Concept]* | *DeepSeek AI [Current Reality]* |
| :--- | :--- | :--- |
| *Core Idea* | Engineered, genuine, non-imitative intelligence | Highly efficient, open-source Artificial Intelligence |
| *Nature of Intelligence* | "Real" thinking, potentially different from human cognition | Simulated intelligence; mimics human-like reasoning based on data patterns |
| *Current State* | Philosophical goal; not yet realized | A series of released, state-of-the-art AI models (e.g., DeepSeek-R1, V3.1) |
| *Key Achievement* | N/A (Conceptual) | Developed a model rivaling OpenAI's performance at a fraction of the cost (<$6M for R1) |
### 💡 Putting It All Together
To summarize the key distinctions:
- *SI is a Philosophy, Not a Product: The transition from AI to SI is a **theoretical paradigm shift* being discussed by researchers and philosophers. It represents a future goal for the field, where machines might one day exhibit authentic, non-imitative cognition.
- *DeepSeek is a Leader in Advanced AI, Not SI: DeepSeek's breakthroughs are in making **current-generation AI more efficient, capable, and open-source*. While its "reasoning models" represent a big step forward in mimicking complex thought processes, they are not examples of Synthetic Intelligence as defined by its proponents.
In short, while the ideas you encountered about SI are fascinating and point to the long-term ambitions of the AI field, the impressive work being done by DeepSeek remains firmly in the realm of cutting-edge Artificial Intelligence.
I hope this clarifies the concepts for you. It's an exciting time for AI, and understanding these distinctions is key to following its evolution
