Extreme bariatric endoscopy: stenting to reconnect the pouch to the gastrojejunostomy after a Roux-en-Y gastric bypass.

BACKGROUND

Among the possible complications of bariatric surgery, fistula and partial dehiscence of the gastric suture are well known. Reoperation often is required but results in significant morbidity. Endoscopic treatment of some bariatric complications is feasible and efficient.

METHODS

A modified metallic stent was placed between the gastroaesophageal junction and the alimentary jejunal limb, allowing the passage of a nasoenteric feeding tube into the jejunal limb.

RESULTS

Endoscopy showed disruption of nearly the entire staple line at the gastric pouch. The modified stent was placed and allowed wound healing. After 31 days, the stent had migrated and was removed endoscopically. Total closure of the fistula was reported 30 days afterward.

CONCLUSIONS

Endoscopic treatment of some bariatric surgery complications is feasible and has been reported previously. This report presents a case of a serious leakage treated by placement of a self-expandable metal stent to bridge the fistula.
