Healing of complicated gastric leaks in bariatric patients using endoscopic clips

Endoscopists have used clipping devices to successfully close acute, iatrogenic perforations throughout the gastrointestinal tract. We applied this technology to our bariatric patients, who tend to present with a more delayed anastomotic leak, to determine whether these leaks and fistulae would also heal with endoclip application.

We describe a small series of 2 clinically stable bariatric patients who presented with postoperative anastomotic leaks who met criteria for non-operative therapy. The first underwent a laparoscopic Roux-en-Y gastric bypass and presented postoperatively with a leak at her gastrojejunal anastomosis. The location was not amenable to stent placement; therefore, 2 endoclips were placed. The leak was sealed by fluoroscopic examination 14 d later. The second had a reversal of a previous gastric bypass, creating a new gastrogastric anastomosis. A leak was found at this new connection postoperatively. After failure of a stent to seal the leak, 8 endoclips were used. This patient also had successful closure of her leak on fluoroscopy 14 d postprocedure.

Anastomotic leaks after bariatric surgery can incur severe morbidity, cost, and detriment to patients' quality of life. Unstable patients require operative intervention. Stable patients are candidates for more-conservative measures. Endoscopic stents have been successful in closing gastric leaks, though some are not anatomically amenable to stent placement, and stents also have the potential to migrate distally. We demonstrate 2 cases of successful closure of leaks in bariatric patients by using endoclips and suggest that this be considered an option in appropriate cases.
