Robotic- vs laparoscopic-assisted proctectomy for locally advanced rectal cancer based on propensity score matching: Short-term outcomes at a colorectal center in China.

Abstract：

BACKGROUND:Reports in the field of robotic surgery for rectal cancer are increasing year by year. However, most of these studies enroll patients at a relatively early stage and have small sample sizes. In fact, studies only on patients with locally advanced rectal cancer (LARC) and with relatively large sample sizes are lacking. AIM:To investigate whether the short-term outcomes differed between robotic-assisted proctectomy (RAP) and laparoscopic-assisted proctectomy (LAP) for LARC. METHODS:The clinicopathological data of patients with LARC who underwent robotic- or laparoscopic-assisted radical surgery between January 2015 and October 2019 were collected retrospectively. To reduce patient selection bias, we used the clinical baseline characteristics of the two groups of patients as covariates for propensity-score matching (PSM) analysis. Short-term outcomes were compared between the two groups. RESULTS:The clinical features were well matched in the PSM cohort. Compared with the LAP group, the RAP group had less intraoperative blood loss, lower volume of pelvic cavity drainage, less time to remove the pelvic drainage tube and urinary catheter, longer distal resection margin and lower rates of conversion (P < 0.05). However, the time to recover bowel function, the harvested lymph nodes, the postoperative length of hospital stay, and the rate of unplanned readmission within 30 days postoperatively showed no difference between the two groups (P > 0.05). The rates of total complications and all individual complications were similar between the RAP and LAP groups (P > 0.05). CONCLUSION:This retrospective study indicated that RAP is a safe and feasible method for LARC with better short-term outcomes than LAP, but we have to admit that the clinically significant of part of indicators are relatively small in the practical situation.
