Non-operative Management of Necrotic Pancreatic Collection and Bleeding Pseudoaneurysm Communicating with Bowel Lumen at Multiple Sites: a Case Report and Review of the Literature
Bibliographic record
Abstract
Pancreatic pseudocysts and foci of walled-off necrosis (WON) are well-known complications of acute pancreatitis. We present a case of severe gallstone pancreatitis complicated by WON, fistulization to the bowel and gastrointestinal bleeding. Bleeding was localized to a pseudoaneurysm of the gastroduodenal artery within the WON using imaging and endoscopy. Angiography and image-guided therapy were then used to control bleeding with coil-embolization. To our knowledge, this is the first report of non-operative management of a patient with severe pancreatitis complicated by WON and a bleeding pseudoaneurysm with multiple communications to the hollow viscera. Therapeutic options are discussed and a thorough literature review is included. Abbreviations: EGD: esophagogastroduodenoscopy; ERCP: endoscopic retrograde cholangiopancreatography; GDA: gastroduodenal artery; GI: gastrointestinal; IEP: interstitial edematous pancreatitis; IPDA: inferior pancreaticoduodenal artery; WON: walled-off necrosis.

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.
