Management of Gastrojejunal Anastomotic Leaks after Roux-en-Y Gastric Bypass

Abstract

Anastomotic leaks after Roux-en-Y gastric bypass (RYGB) potentially result in considerable morbidity and mortality. In the present report we describe our experience with the management of gastrojejunal anastomotic leaks. Tachycardia and fever are considered early signs of anastomotic disruption. Patients weighing less than 350 pounds underwent radiographic testing to diagnose gastrojejunal disruption. Those with severe leaks or patients too large for radiographic evaluation underwent exploratory laparotomy. For severe anastomotic disruptions a retrograde transanastomotic jejunal sump drain was placed. Twenty-four (1.3%) anastomotic leaks occurred in 1789 RYGBs. Five of the leaks were classified as severe and required retrograde sump tube placement. There was one mortality and all of the other patients completely recovered. Aggressive and early intervention for anastomotic disruption after RYGB is necessary to ensure the best possible outcomes for patients with this complication. A high index of suspicion for leaks in postoperative RYGB patients with tachycardia is required if patients are to have good outcomes when complications develop.
