# Left gastric artery embolization for recurrent massive intraluminal postoperative bleeding after revisional laparoscopic one anastomosis gastric bypass surgery

## TL;DR

This paper presents a case where embolization of the left gastric artery successfully stopped recurrent bleeding after gastric bypass surgery, though it later caused pancreatitis.

## Contribution

The paper highlights the use of left gastric artery embolization as a successful treatment for postoperative bleeding after LOAGB.

## Key findings

- Left gastric artery embolization successfully stopped recurrent postoperative bleeding after LOAGB.
- The patient later developed necrotizing pancreatitis following the embolization.
- TAE has high technical success and moderate clinical success rates in post-gastrectomy bleeding.

## Abstract

Laparoscopic one-anastomosis gastric bypass (LOAGB) has gained popularity as safe weight-reduction procedure. Bleeding is the common postoperative complication. We present a successful treatment of recurrent bleeding after LOAGB by embolization of the left gastric artery (LGA) and later development of necrotizing pancreatitis. A 41-year-old patient with previous bariatric surgeries undergone LOAGB surgery with development of massive intraluminal bleeding in the postoperative period. Attempts of unsuccessful endoscopic treatment were done and the bleeding was stopped by LGA embolization. In the post-embolization period, the patients developed necrotizing pancreatitis. Postoperative bleeding is the serious complications of the bariatric LOAGB procedure. Transcatheter Arterial Embolization (TAE) is the possible treatments after unsuccessful endoscopic attempts to stop the bleeding. The technical and clinical success rates of TAE in post-gastrectomy bleeding are 100 and 79%, respectively. TAE can be successfully used to stop obstinate recurrent postoperative bleeding after a LOAGB procedure.
