    Abstract Aim: The aim was to develop and operationally define 'performance metrics' that characterize a reference approach to robotic-assisted low anterior resection (RA-LAR) and to obtain face and content validity through a consensus meeting.
    Method: Three senior colorectal surgeons with robotic experience and a senior behavioural scientist formed the Metrics Group. We used published guidelines, training materials, manufacturers' instructions and unedited videos of RA-LAR to deconstruct the operation into defined, measurable components - performance metrics (i.e. procedure phases, steps, errors and critical errors). The performance metrics were then subjected to detailed critique by 18 expert colorectal surgeons in a modified Delphi process.
    Results: Performance metrics for RA-LAR had 15 procedure phases, 128 steps, 89 errors and 117 critical errors in women, 88 errors and 118 critical errors in men. After the modified Delphi process the final performance metrics consisted of 14 procedure phases, 129 steps, 88 errors and 115 critical errors in women, 87 errors and 116 critical errors in men. After discussion by the Delphi panel, all procedure phases received unanimous consensus apart from phase I (patient positioning and preparation, 83%) and phase IV (docking, 94%).
    Conclusion: A robotic rectal operation can be broken down into procedure phases, steps, with errors and critical errors, known as performance metrics. The face and content of these metrics have been validated by a large group of expert robotic colorectal surgeons from Europe. We consider the metrics essential for the development of a structured training curriculum and standardized procedural assessment for RA-LAR.

    Abstract For T4 rectal tumours and local recurrences (LR) of rectal cancer, a radical resection beyond TME, sometimes by multi-visceral resection, is important to obtain safe margins and improve survival. The use of the laparoscopic approach (LA) for these cases is still controversial and associated with a high rate of conversion. However, robotic surgery might offer some advantages that can overcome some of the limitations of LA. Therefore, we aimed to analyse the postoperative outcomes and medium-term oncological results of robotic surgery for locally advanced rectal cancer (pathological T4) and LR. A retrospective analysis was performed including patients who had undergone robotic rectal resection in a single institution over an 11-year period, and had a T4 tumour confirmed in the pathological report. Primary endpoint was to analyse postoperative complications (30-day) and the rate of conversion. Secondary endpoints include pathological assessment of the quality of the specimen, local recurrence and survival [2-year disease-free survival (DFS) and overall survival (OS)]. A total of 41 patients were analysed, including a total of 24 patients (60%) that required a multivisceral resection. The median distance from the tumour to the anorectal junction was 7 (4-12) cm. Conversion to open surgery was necessary in 2 cases (5%). The overall morbidity rate was 78% (n = 32), with 37% of major complications, most of them urinary (n = 7). Median length of hospital stay (LOS) was 13 (7-27) days. The 30-day mortality rate was 7% (n = 3). An R0 resection was achieved in 85.4% of the cases (n = 35) due to 6 cases of the positive circumferential resection margin. 2-year disease-free survival (DFS) and overall survival (OS) for the T4 tumours were 72% and 85%, respectively. There were 8 cases of local recurrence (22.2%); 6 of them met the selection criteria for salvage surgery. Robotic surgery for locally advanced T4 rectal cancer and multi-visceral resections is safe and feasible, with a low rate of conversion and an acceptable rate of postoperative morbidity in this subgroup of patients. Oncological results have shown to be comparable with the laparoscopic series published, preserving a good quality of the resected specimen. However, comparative studies and a longer follow-up period is needed to confirm the oncologic findings and to support the general adoption of the robotic system for these complex interventions.
