Abdominal pain post bariatric procedure: What is the cause?
Bibliographic record
Abstract
Omental ischemia after bariatric surgery is a rare cause of abdominal pain. We report a case of a 42-year-old female with a history of Roux-en-Y gastric bypass (RYGB) presenting with abdominal pain. Despite biochemical, radiologic, and endoscopic investigation, no cause was identified. Ultimately, diagnostic laparoscopy revealed ischemic omentum. Post-operatively, her symptoms resolved. This case highlights the diagnostic challenges in patients post-RYGB presenting with abdominal pain with no clear cause. Division of the omentum is common practice during RYGB in the case of an antecolic Roux limb. This may predispose patients to omental infarction and ischemia, and as such, suspicion should be high when initial investigations are equivocal. The potential role of omental division during RYGB warrants further investigation. Furthermore, this case reinforces the importance of diagnostic laparoscopy in select cases. Rare causes of abdominal pain, such as omental ischemia, should be considered in patients who are post- RYGB. When initial investigations are negative, early diagnostic laparoscopy should be considered.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
