Rectal Surgery Evaluation Trial:protocol for a parallel cohort trial of outcomes using surgical techniques for total mesorectal excision with low anterior resection in high‐risk rectal cancer patients

Abstract Aim: Total mesorectal excision (TME) is the standard of care for rectal cancer, which can be combined with low anterior resection (LAR) in patients with mid‐to‐low rectal cancer. The narrow pelvic space and difficulties in obtaining adequate exposure make surgery technically challenging. Four techniques are used to perform the surgery: open laparotomy, laparoscopy, robot‐assisted surgery and transanal surgery. Comparative data for these techniques are required to provide clinical data on the surgical management of rectal cancers. Methods: The Rectal Surgery Evaluation Trial will be a prospective, observational, case‐matched, four‐cohort, multicentre trial designed to study TME with LAR using open laparotomy, laparoscopy, robot‐assisted surgery or transanal surgery in high‐surgical‐risk patients with mid‐to‐low non‐metastatic rectal cancer. All surgeries will be performed by surgeons experienced in at least one of the techniques. Oncological, morbidity and functional outcomes will be assessed in a composite primary outcome, with success defined as circumferential resection margin ≥ 1 mm, TME Grade III and minimal postoperative morbidity (absence of Clavien–Dindo Grade III–IV complications within 30 days after surgery). Secondary end‐points will include the co‐primary end‐points over the long term (2 years), quality of surgery, quality of life, length of hospital stay, operative time and rate of unplanned conversions. Discussion: This will be the first trial to study all four surgical techniques currently used for TME with LAR in a specific group of high‐risk patients. The knowledge obtained will contribute towards helping physicians determine the advantages of each technique and which may be the most appropriate for their patients

Expert consensus on a train-the-trainer curriculum for robotic colorectal surgery

Aim: Robotic techniques are being increasingly used in colorectal surgery. There is, however, a lack of training opportunities and structured training programmes. Robotic surgery has specific problems and challenges for trainers and trainees. Ergonomics, specific skills and user–machine interfaces are different from those in traditional laparoscopic surgery. The aim of this study was to establish expert consensus on the requirements for a robotic train-the-trainer curriculum amongst robotic surgeons and trainers. Method: This is a modified Delphi-type study involving 14 experts in robotic surgery teaching. A reiterating 19-item questionnaire was sent out to the same group and agreement levels analysed. A consensus of 0.8 or higher was considered to be high-level agreement. Results: Response rates were 93–100% and most items reached high levels of agreement within three rounds. Specific requirements for a robotic faculty development curriculum included maximizing dual-console teaching, theatre team training, nontechnical skills training, patient safety, user–machine interface training and telementoring. Conclusion: A clear need for the development of a train-the-trainer curriculum has been identified. Further research is needed to assess feasibility, effectiveness and clinical impact of a robotic train-the-trainer curriculum
