Comparison of short‐term outcomes of robotic‐assisted and conventional laparoscopic surgery for rectal cancer: A propensity score‐matched analysis

Introduction The advantages of robotic‐assisted laparoscopic surgery (RALS) for rectal cancer remain controversial. This study clarified and compared the short‐term outcomes of RALS for rectal cancer with those of conventional laparoscopic surgery (CLS). Methods The records of 303 consecutive patients who underwent RALS or CLS for rectal adenocarcinoma between November 2016 and November 2021 were analyzed using propensity score‐matched analysis. After matching, 188 patients were enrolled in our study to compare short‐term outcomes, such as operative results, postoperative complications, and pathological findings, in each group. Results After matching, baseline characteristics were comparable between groups. Although operative time in the RALS group was significantly longer than in the CLS group (p
