Structured training pathway for robotic colorectal surgery: Short-term outcomes from five UK centres

The aim of this study was to assess the short-term outcomes of robotic colorectal surgery implemented through a structured, standardized training pathway in five colorectal centres in the United Kingdom.

A multicentre retrospective observational study was conducted, involving 523 consecutive patients who underwent robotic colorectal resection between 2015 and 2019. All participating centres followed the European Academy of Robotic Colorectal Surgery training pathway. Patient data, including demographics, operative details, postoperative outcomes and pathology results, were collected and analysed.

The study included 447 rectal resections and 76 colonic operations. The median age of the patients was 64.7 years, with the majority of patients (70%) being men. The mean body mass index was 27.4 kg/m², and 89.7% of the patients underwent surgery for malignancy. The overall conversion rate to open surgery was 4.2%. The median length of stay was 6 days and there was no 30-day mortality. The readmission and reoperation rates were 8.8% and 7.3%, respectively. The anastomotic leak rate was 4.1% for rectal resections and 3.9% for colonic resections. Pathological examination showed a positive circumferential resection margin rate of 2.6%.

Through the implementation of a structured, standardized training pathway, the participating colorectal centres in the UK achieved safe and effective robotic colorectal surgery pathways with favourable short-term oncological and clinical outcomes. Further studies examining long-term and functional outcomes are needed to assess the broader impact of robotic surgery in colorectal procedures.
