Safety of modified double‐stapling end‐to‐end gastroduodenostomy in distal subtotal gastrectomy

Abstract

BACKGROUND AND OBJECTIVES: Double-stapling end-to-end gastroduodenostomy (DS-BI) has several potential advantages over other anastomotic techniques in that it is a simple procedure, with no additional gastrotomy on the remnant stomach, and less tension on the anastomosis site. We evaluated the safety of DS-BI by comparing it with the hand-sewn Billroth II gastrojejunostomy (B-II). METHODS: Medical records of 933 consecutive patients (DS-BI 428, B-II 505) who underwent distal subtotal gastrectomy were retrospectively reviewed. Several clinicopathological features and treatment results were compared between the two groups. RESULTS: The overall complication rates were 9.3% in the DS-BI group and 15.2% in the B-II group (P = 0.007). Anastomosis-related complications, such as anastomosis-site leakage, stenosis, and intraluminal bleeding, did not differ between the two groups (1.2% in the DS-BI group and 1.8% in the B-II group, P = 0.59). All the anastomosis-related complications were managed conservatively. Postoperative mortality rates were 0% in the DS-BI group and 0.4% (2/505) in the B-II group. CONCLUSIONS: Modified DS-BI is a safe procedure, with short-term results similar to those of hand-sewn Billroth II anastomosis.
