Staple-Line Reinforcement of the Duodenal Stump With Intracorporeal Lembert's Sutures in Laparoscopic Distal Gastrectomy With Roux-en-Y Reconstruction for Gastric Cancer.

Abstract We report a duodenal stump reinforcement procedure in laparoscopic distal gastrectomy with Roux-en-Y reconstruction. We retrospectively reviewed the data of 223 patients who underwent laparoscopic distal gastrectomy with Roux-en-Y reconstruction for gastric cancer. We compared 2 groups: group NR (not reinforced, n=102, June 2009 to December 2011) when we did not perform reinforcement of the duodenal stump, and group R (reinforced, n=121, January 2012 to July 2014) when we did the reinforcement. The duodenum was divided with an endoscopic linear stapler. In group R, the duodenal staple line was reinforced by hand-sewn Lembert's sutures. There were no significant differences between group NR and R in patients' characteristics. Duodenal stump leakage occurred in 2 patients in group NR (2.0%). By contrast, in R group, no patients had duodenal stump leakage or fistula. Duodenal stump leakage can be avoided by using reinforcement with Lembert's sutures.
