INTRODUCTION: Delta-shaped anastomosis has been recognized as a method of intracorporeal Billroth I anastomosis in totally laparoscopic distal gastrectomy. However, the technical aspects and outcomes of the delta-shaped anastomosis in totally robotic distal gastrectomy have never been reported.

METHODS: A single-institutional, non-randomized, retrospective study was performed between 2009 and 2013. During the study period, 47 patients underwent robotic distal gastrectomy followed by robotic delta-shaped Billroth I reconstruction, and 165 patients underwent conventional laparoscopic distal gastrectomy followed by laparoscopic delta-shaped Billroth I reconstruction. After 64 were excluded because of insufficient intraoperative video, 43 patients in the robotic group and 105 patients in the laparoscopic group were enrolled in the study. Short-term outcomes were determined from medical records and full-length operative videos.

RESULTS: There were no significant differences between the robotic and laparoscopic groups in terms of morbidity (4.7% vs 3.8%), anastomosis-related complications (0% vs 1.0%), non-anastomosis-related complications (2.3% vs 0%), or systemic complications (2.3% vs 0%). Time for reconstruction did not vary between the robotic group (16.6 min [8.8-42.9 min]) and the laparoscopic group (15.8 min [7.2-41.0 min]). There was no mortality in this series. In the conventional group, the morbidity rate was 3.8%. The anastomosis-related complication rate was 1.0% in the conventional group.

CONCLUSIONS: Given the excellent short-term outcomes related to anastomosis, delta-shaped anastomosis after robotic distal gastrectomy was at least as feasible and safe as delta-shaped anastomosis after laparoscopic distal gastrectomy.
