AIM: Robotic surgery is increasingly being used for rectal resection, with short-term benefits such as reduced hospital stay, faster bowel recovery and fewer complications. However, its utility for advanced rectal cancers requiring beyond total mesorectal excision has not been adequately evaluated. The aim of this study was to compare robotic and laparoscopic approaches for extended rectal resection, with postoperative and short-term oncological outcomes as endpoints.
METHOD: A retrospective, single-centre study of patients with advanced rectal cancer requiring extended rectal resection between January 2017 and December 2022 was carried out. Beyond total mesorectal excisions included pelvic exenteration, en bloc soft tissue or partial organ resection with the rectum, and lateral pelvic node dissection. Propensity score matching in a 4:1 ratio of laparoscopic to robotic was performed with age, sex, comorbidities, body mass index, organs involved, clinical T stage and colonoscopic obstruction.
RESULTS: A total of 425 beyond total mesorectal excisions were performed by minimally invasive approaches during the study period, and after propensity matching 228 laparoscopic operations were compared with 57 robotic resections. All baseline characteristics were balanced. No difference in blood loss, postoperative complications, length of hospital stay, positive resection margin or nodal yield was found, but there was a somewhat longer operating duration in robotics. The 2-year disease-free and overall survival were also similar.
CONCLUSIONS: No differences in postoperative or short-term oncological outcomes were found between robotic and laparoscopic beyond total mesorectal excisions for advanced tumours when performed by teams experienced in both robotics and laparoscopy.
