Although there’s growing information about the long-term oncological effects of robotic surgery for rectal cancer, the procedure is still relatively new. This study aimed to assess the long-term oncological results of total mesorectal excision (TME) performed laparoscopically versus robotically in the setting of rectal cancer. Restrospective analysis of a prospectively maintained database. A total of 489 laparoscopic (L-TME) and 183 robotic total mesorectal excisions (R-TME) were carried out by a single surgeon between 2013 and 2023. The groups were compared in terms of perioperative and long-term oncological outcomes. In the R-TME and L-TME groups, male sex predominated (75.4% and 57.3%, respectively), although the robotic group was significantly greater (p = 0.008). There was no conversion in R-TME group, whereas three (0.6%) converted to open surgery in L-TME group. The R-TME group had a statistically significant higher number of distal rectal tumors (85%) compared to the L-TME group (54.6%). Only three (1.7%) patients in the R-TME group received abdomineperineal resection (APR); in contrast, 25 (5%) patients in the L-TME group received APR (p < 0.001). For R-TME, the mean follow-up was 70.7 months (range 18–138) and for L-TME, it was 60 months (range 14–140). Frequency of completed mesorectum was significantly greater in R-TME group (98.9% vs 94.2%, p < 0.001). The 5 year overall survival rates for R-TME and L-TME groups were 89.6% and 88.7%, respectively. The 5 year disease-free survival for R-TME and L-TME groups were 84.1% and 81.1%, respectively. The local recurrences rates were 7.6% and 6.3%, respectively in R-TME and L-TME groups (p = 0.274). R-TME is characterized by no conversion and improved mesorectal integrity. R-TME had longer operation time. The long-term oncological outcomes were comparable between groups.
