Short-term outcomes of laparoscopic total gastrectomy for gastric cancer: a comparative study with laparoscopic distal gastrectomy at a high-volume center

Abstract

Background: Laparoscopic distal gastrectomy (LDG) for gastric cancer has gradually gained popularity. However, laparoscopic total gastrectomy (LTG) has been reported rarely when compared with LDG. This study was designed to evaluate the surgical outcomes as well as the morbidity and mortality of LTG compared with LDG to confirm the feasibility and safety of LTG.Material and methods: We reviewed the data of patients at our institution undergoing LTG (n = 448) or LDG (n = 956) for gastric cancer between January 2008 and July 2016. Then the clinical characteristics and perioperative clinical outcomes of the two groups were compared.Results: Except for tumor size and stage, there were no statistically significant differences in the clinicopathological parameters between the groups. LTG was associated with significantly longer operation time, late time to postoperative diet, and longer hospital stay compared with the LDG group. Overall complications developed in 60 patients (13.4%) and surgical complications in 48 patients (10.7%) after LTG. Postoperative complications were less frequent in the LDG group than in the LTG group (8.4% versus 13.4%, p < .01), and fewer surgical complications were observed with LDG than with LTG (7.5% versus 10.7%, p = .05).Conclusions: The results of LTG were favorable even though are not inferior to those of LDG. LTG for gastric cancer is technically feasible and safe. However, because of the limits of this study, other high-quality studies are needed for further evaluation.
