Abstract
BackgroundRobotic distal gastrectomy (RDG) has been increasingly used for the treatment of gastric cancer (GC). However, whether RDG has a clinical advantage over laparoscopic distal gastrectomy (LDG) is yet to be determined. Thus, this study aimed to assess the feasibility and safety of RDG for the treatment of GC as compared with LDG.MethodsIn total, 157 patients were enrolled between February 2018 and August 2020 in this retrospective study. We then compared the surgical outcomes between RDG and LDG using propensity score-matching (PSM) analysis to reduce the confounding differences.ResultsAfter PSM, a clinicopathologically well-balanced cohort of 100 patients (50 in each group) was analyzed. The operation time for the RDG group (350.1 ± 58.1 min) was determined to be significantly longer than that for the LDG group (257.5 ± 63.7 min; P < 0.0001). Of interest, there was a decreased incidence of pancreatic fistulas and severe complications after RDG as compared with LDG (P = 0.092 and P = 0.061, respectively). In addition, postoperative hospital stay was statistically slightly shorter in the RDG group as compared with the LDG group (12.0 ± 5.6 vs. 13.0 ± 12.3 days; P = 0.038).ConclusionsOur study confirmed that RDG is a feasible and safe procedure for GC in terms of short-term surgical outcomes. A surgical robot might reduce postoperative severe complications and length of hospital stay.

This study aimed to assess the short-term surgical outcomes between RDG and laparoscopic distal gastrectomy (LDG) using propensity score-matching (PSM) analysis to adjust for patient background data as far as possible
We used the following as inclusion criteria for the study: all patients diagnosed with GC via pathological biopsy and those with clinical T1-4N0-3M0 GC based on the Japanese classification of gastric carcinoma (JCGC) [12]
Summary
Robotic distal gastrectomy (RDG) has been increasingly used for the treatment of gastric cancer (GC). This study aimed to assess the feasibility and safety of RDG for the treatment of GC as compared with LDG. Since Kitano et al first performed laparoscopically assisted gastrectomy for GC in 1991, minimally invasive surgery with laparoscopy has gradually been accepted as a common surgical procedure. Several studies have compared the safety and feasibility of robotic distal gastrectomy (RDG) and LDG [2, 10, 11]. Most of these studies did not take all the background data into consideration. This study aimed to assess the short-term surgical outcomes between RDG and LDG using propensity score-matching (PSM) analysis to adjust for patient background data as far as possible
