An additional suture secures against pitfalls in delta-shaped gastroduodenostomy after laparoscopic distal gastrectomy.

Laparoscopic gastrectomy is widely used as a minimally invasive surgery for gastric cancer. Laparoscopic distal gastrectomy must be followed by either a gastroduodenostomy or gastrojejunostomy to restore continuity of the alimentary tract. The intraabdominal delta-shaped gastroduodenostomy using endoscopic linear staplers, which was developed by Kanaya et al., is one of the feasible reconstructive procedures. However, the clinical results still remain uncertain. In 71 patients treated between February 2008 and February 2009, we found that anastomotic failure occurred in six patients and there was an intraabdominal abscess around the anastomosis in two patients, findings which might be associated with technical pitfalls in the procedure. After considering the mechanisms underlying these unfavorable complications, we developed a modification of the procedure to successfully overcome these complications by reinforcement of the anastomosis using simple suturing at the closed common channel on the greater curvature. This modified Kanaya's procedure will be safer and should provide a better intracorporeal gastroduodenostomy after laparoscopic distal gastrectomy.
