Pneumothorax/Pneumomediastinum/Pneumoperitoneum: A Very Rare Complication of ERCP
Bibliographic record
Abstract
We present a 26-year-old Indian female who presented to the hospital with symptoms of right upper quadrant abdominal pain. Workup was suggestive of cholelithiasis and choledocholithiasis. Patient underwent urgent endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and had successful removal of a stone along with stent placement. Patient developed post-operative back pain and chest pain. Workup revealed retroperitoneal air, pneumoperitoneum, pneumomediastinum and right sided pneumothorax; gastrointestinal series (UGI) gastrograffin study was negative for any leak. Patient underwent chest tube placement which resolved the pneumothorax. Pt improved with non-operative management and did not require any surgical intervention for retroperitoneal duodenal perforation. This is a very rare complication of ERCP described in literature in some case reports and needs to always be considered as missing such complications can have significant morbidity/mortality.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
