BACKGROUND: Overlap anastomosis is widely used in gastrointestinal reconstruction during minimally invasive gastrectomy. The entry hole of the anastomosis is typically closed with hand-sewn sutures because of concerns about stenosis. This study aimed to compare the efficacy of linear stapler (LS) closure with that of hand-sewn closure of the entry hole in overlap anastomosis.
METHODS: We included 172 patients who underwent overlap anastomosis during laparoscopic or robot-assisted total gastrectomy (TG, Roux-en-Y) or distal gastrectomy (DG, Roux-en-Y/Billroth II) between February 2020 and September 2024. The patients were divided into two groups based on the method of entry hole closure: the suturing group (S group) and the LS group. Surgical outcomes were retrospectively analyzed.
RESULTS: There were no significant differences in patient characteristics or tumor staging between the two groups. TG was performed in 46 and 17 patients in the S and LS groups, respectively, whereas DG was performed in 41 and 68 patients in the S and LS groups, respectively. In TG patients, there was no significant difference in operative time, but the esophageal-jejunal overlap anastomosis time was significantly shorter in the LS group (38.3 vs. 20.5 min, P < 0.001). The incidence of postoperative complications was similar in both groups, and no cases of stenosis were observed in the LS group. In DG patients, the operative time and gastric-jejunal overlap anastomosis time were significantly shorter in the LS group (294 min vs. 253 min, P = 0.002; 28.5 vs. 9.0 min, P < 0.001). The length of postoperative hospital stay was significantly shorter in the LS group (13 vs. 11 days, P = 0.01).
CONCLUSION: Using an LS to close the entry hole in an overlapping anastomosis during minimally invasive gastrectomy can reduce the anastomosis time and may be a safe option without increasing the risk of stenosis.
