Abstract
Background Expensive cost of surgery has limited the use of surgical robot in China. The emergence of “Micro Hand S” surgical robot provides more choices for surgical treatment. Our study was to evaluate the safety and feasibility of “Micro Hand S” surgical robotic gastrectomy for gastric cancer. Methods Perioperative data of 75 patients who underwent “Micro Hand S” surgical robotic gastrectomy (RG) or laparoscopic gastrectomy (LG) at the Department of General Surgery, Third Xiangya Hospital, Central South University from June 2017 to January 2019 were collected to compare the short-term outcomes between the two groups. Results No statistically significant difference was found in baseline characteristics between the two groups (P > 0.05). RG group had longer operation time (P < 0.01). The harvested lymph nodes were comparable between the two groups (P = 0.084). There were five positive margins in the LG group, and the R0 resection rate was comparable between the two groups (P = 0.247). 16 complications occurred in the RG group according to the Clavien-Dindo classification system, 6 in grade I, and 10 in grade II. 68 complications happened in the LG group, 22 in grade I, 44 in grade II, 1 in grade IIIa and 1 in grade IVa. The comprehensive complications index (CCI) was similar between the two groups (P = 0.895). Intraoperative blood loss, surgical resection, reconstruction of the digestive tract intraoperative blood transfusion, Chemoradiotherapy, pathological type, degree of differentiation, proximal resection margin, time of first flatus, time of liquid diet, time of abdominal drainage tube extraction, and hospital stay for RG and LG were similar too (P > 0.05). Conclusion “Micro Hand S” surgical robotic gastrectomy is safe and feasible. Keywords Surgical robot; Gastric cancer; Gastrectomy; Safety; Feasibility
