Safety of double and a half-layered esophagojejunal anastomosis in total gastrectomy with gastric cancer.

Abstract

e16563 Background: Esophageal jejunal anastomotic fistula is still one of the serious postoperative complications of gastric cancer, the incidence was 1% ~ 16.5%. The aim of this study was to evaluate the safety of double and a half layered esophagojejunal anastomosis in total gastrectomy. Methods: The new method was called double and a half layered esophagojejunal anastomosis: esophagojejunal anastomosis was performed with a tubular stapler, then the anastomosis was reinforced by absorbable suture (Full-layer continuous suture, slurry muscularis embedding). The new method was used in observation group (n = 295). In the control group(n = 469),the esophagojejunal anastomosis was performed with a tubular stapler, then reinforced by intermittent suture with absorbable sutures. Data analysis including operating time, blood loss, anastomosis time, types and cases of postoperative complications, and postoperative hospitalization time. Results: The data of 764 patients who performed radical gastrectomy between May 2015 and May 2019 were analyzed retrospectively. 1.Surgery situations: The operating time (140.66±26.96 min vs 139.61±22.75min, t= 0.581, P> 0.05) blood loss (200.61±111.03ml vs214.45±114.09ml, t= -1.481, P> 0.05), anastomosis time (20.44±4.31min vs19.92±4.58min, t= 1.573, P> 0.05), postoperative hospitalization time (15.35±6.46 d vs15.89±5.58d, t= -1.229, P> 0.05) .2. Postoperative situations: the rates of anastomotic complications in observation group was 1.69% (5/295) and 4.69% (22/469) in control group, with a statistically significant difference between two groups( χ2 = 4.768, P< 0.05). The rates of anastomotic leakage in observation group was lower than that in the control group 1.02% (3/295) vs 3.41% (16/469) ( χ2 = 4.282, P< 0.05) . The severity of anastomotic leakage, anastomotic stenosis, anastomotic bleeding were no statistically significant differences between two groups( χ 2= 2.030,1.261,0.075, P> 0.05). Total postoperative complications: 101 cases (34.24%) in the observation group, 14 cases (4.75%) with severe complications, and 1 case death. 151 cases (32.2%) in the control group, 34 cases (7.25%) with serious complications, and 2 cases death ( χ2 = 0.838, Z = -1.465, P > 0.05). Conclusions: Double and a half layered esophagojejunal anastomosis is safe and feasible in total gastrectomy, which can reduce the incidence of anastomosis complications.
