Consensus-led recommendations defining practical principles of achieving optimal surgical outcomes in robotic colorectal surgery in the Asia-Pacific region

Recent innovations within the field of robotic surgery have particular relevance to colorectal surgery. Although a robotic approach has been associated with satisfactory outcomes, there remains a wide variation in levels of adoption. In particular, this study focuses on patient positioning, docking, and table placement, with the intent of understanding the strength of opinion of colorectal surgeons in the Asia-Pacific region to the practical application of these developments to achieve optimal surgical outcomes. Using a modified Delphi methodology, a steering group of colorectal surgeons with experience in robotic surgery from across the Asia-Pacific region identified 35 consensus statements. An online 4-point Likert scale questionnaire was distributed to surgeons in the Asia-Pacific region using convenience sampling. Respondents were excluded from further analysis if they did not perform colorectal surgery or had no experience in robotic surgery. A total of 140 responses (71.8% response rate) were received between August and October 2021. 22 statements attained a very high degree of agreement (>= 90%). High agreement (< 90% and >= 75%) was achieved in another 12, and one failed to meet the consensus threshold (< 75%). A set of five recommendations were developed based on these results. The high levels of agreement demonstrate recognition amongst colorectal surgeons within the Asia-Pacific region of the potential advantage of recent improvements in robotic surgery technology to further improve surgical outcomes. The recommendations may inform a set of practical principles to help standardise the use of colorectal robotic surgery, which may also be relevant to other surgical fields.
