Abstract
Robotic-assisted surgery (RAS) is becoming increasingly common for the surgical treatment of rectal cancer. However, the use and implementation of robotic surgery remains controversial. This study aimed to compare the short-term outcomes of robotic surgery, focusing on pathological results and disease-free survival (DFS), in our cohort with initial robotic experience by multiple surgeon implementation. This retrospective study enrolled 571 patients diagnosed with rectal cancer, who were treated with chemoradiotherapy and surgery between January 2015 and December 2021. Surgical outcomes after RAS and laparoscopic surgery (LS) were compared using a propensity score-matching (PSM) analysis. After matching, 200 patients (100 in each group) were included. The median operative time was significantly longer in the RAS group than in the LS group (p < 0.001). The conversion and morbidity rates were similar between the groups. A significantly higher rate of complete mesorectal excision (92% vs. 72%; p = 0.001) and number of lymph nodes harvested (p = 0.009) was observed in the RAS group. There were no statistically significant differences between the groups regarding circumferential and distal resection margin involvement. The 3-year overall and disease-free survival rate was similar between the two groups (p = 0.849 and p = 0.582, respectively). Two patients in the LS group developed local recurrence and 27 patients (15.4%) developed metastatic disease. Multivariate analysis showed that tumor stage III was the only factor associated with disease-free survival (HR, 9.34; (95% CI 1.13-77.1), p = 0.038). RAS and LS showed similar outcomes in terms of perioperative, anatomopathological, and disease-free survival, after multiple surgeon implementations.

Local recurrence of robot-assisted total mesorectal excision: a multicentre cohort study evaluating the initial cases. Int J Colorectal Dis 2022; 37:1635-1645. [PMID: 35708836 PMCID: PMC9262776 DOI: 10.1007/s00384-022-04199-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 06/03/2022] [Indexed: 02/04/2023]
Abstract
PURPOSE Evidence regarding local recurrence rates in the initial cases after implementation of robot-assisted total mesorectal excision is limited. This study aims to describe local recurrence rates in four large Dutch centres during their initial cases. METHODS Four large Dutch centres started with the implementation of robot-assisted total mesorectal excision in respectively 2011, 2012, 2015, and 2016. Patients who underwent robot-assisted total mesorectal excision with curative intent in an elective setting for rectal carcinoma defined according to the sigmoid take-off were included. Overall survival, disease-free survival, systemic recurrence, and local recurrence were assessed at 3 years postoperatively. Subsequently, outcomes between the initial 10 cases, cases 11-40, and the subsequent cases per surgeon were compared using Cox regression analysis. RESULTS In total, 531 patients were included. Median follow-up time was 32 months (IQR: 19-50]. During the initial 10 cases, overall survival was 89.5%, disease-free survival was 73.1%, and local recurrence was 4.9%. During cases 11-40, this was 87.7%, 74.1%, and 6.6% respectively. Multivariable Cox regression did not reveal differences in local recurrence between the different case groups. CONCLUSION Local recurrence rate during the initial phases of implantation of robot-assisted total mesorectal procedures is low. Implementation of the robot-assisted technique can safely be performed, without additional cases of local recurrence during the initial cases, if performed by surgeons experienced in laparoscopic rectal cancer surgery.
