Omental Artery Bleeding: A Rare Complication of Percutaneous Cholecystostomy
Bibliographic record
Abstract
Abstract Background: Percutaneous cholecystostomy (PCC) is often performed to treat acute cholecystitis in critically ill or high-risk surgical patients. This case report illuminates a rare complication following PCC that has not been previously reported in the literature. Case Presentation: A 49-year-old male with a complex medical history presented with symptoms indicative of cholecystitis which was confirmed on imaging. The patient underwent PCC with no intra-procedural complications. Post-procedure, the patient experienced a significant drop in vital signs with intraperitoneal free fluid on CT. Prompt fluoroscopy-guided angiography that identified bleeding from an omental artery, along with subsequent embolization of the bleeding artery were crucial in stabilizing the patient's condition. Conclusion: This case report underscores the importance of comprehensive anatomical understanding, procedural vigilance, and swift response to complications during PCC. The uniqueness of this case lies in the rarity of the complication and the successful management, thereby enriching the existing compendium of knowledge on PCC-associated risks.

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.
