Abstract:

Objective To compare the short⁃term efficacy of robotic versus laparoscopic radical gastrectomy in gastric cancer patients with varying Body Mass Index（BMI）. Methods From January 2021 to June 2022，the clinicopathological data of 443 patients with gastric cancer who underwent surgical treatment in the Seventh General Ward of the First Affiliated Hospital of Nanchang University were collected. Among them ，there were 68 cases in the lean group，238 cases in the normal group，and 137 cases in the overweight group. The three groups were compared in terms of baseline data，pathological data，intraoperative and postoperative short⁃term efficacy of robotic and laparoscopic radical gastrectomy. Results In the lean group，the robotic group had a shorter postoperative eating time［3（2，3）vs. 3（3，4）］days. In the normal group：patients in the robotic group significantly shortened the total operation time［172（144，205）vs. 215（175，259）］min including separation and reconstruction time，time for eating and indwelling［3（3，4）vs. 3（3，5）］days，drainage tube removal time［6（6，8）vs. 7（6，8）］days and postoperative hospital stay［8（7，10）vs. 7（7，9）］days. In the overweight group，the robotic group reduced total operative time［190（170，237）vs. 240（192，297）］min including dissection and reconstruction time，drain removal time［6（6，7）vs. 6（5，6）］days ，postoperative hospital stay［7（7，8）vs. 7（6，7）］days and removed more extragastric lymph nodes［14.3 ± 10.6 vs. 10.6 ± 6.9］. Conclusion Robotic operating systems can provide more immediate benefits to gastric cancer patients with high BMI values，and BMI should be considered as an indicator when selecting an operating system before undergoing a radical gastrectomy for gastric cancer.
