The impact of robotic rectal cancer surgery at a Canadian regional cancer centre: a retrospective cohort study.

BACKGROUND: Although robotic surgery has several advantages over other minimally invasive surgery (MIS) techniques for rectal cancer surgery, the uptake in Canada has been limited owing to a perceived increase in cost and lack of training. The objective of this study was to determine the impact of access to robotic surgery in a Canadian setting. METHODS: We conducted a retrospective cohort study involving consecutive adults undergoing surgical resection for rectal cancer between 2017 and 2020. The primary exposure was access to robotic surgery. Outcomes included MIS utilization, short-term outcomes, total cost of care, and quality of surgical resection. We completed univariate and multivariate analyses. RESULTS: We included 171 individuals in this cohort study (85 in the prerobotic period and 86 in the robotic period). The 2 groups had similar baseline characteristics. A higher proportion of individuals underwent successful MIS in the robotic phase (86% v. 46%, p < 0.001). Other benefits included a shorter mean length of hospital stay (5.1 d v. 9.2 d, p < 0.001). The quality of surgical resection was similar between groups. The total cost of care was $16 746 in the robotic period and $18 808 in the prerobotic period (mean difference -$1262, 95% confidence interval -$4308 to $1783; p = 0.4). CONCLUSION: Access to robotic rectal cancer surgery increased successful completion of MIS and shortened hospital stay, with a similar total cost of care. Robotic rectal cancer surgery can enhance patient outcomes in the Canadian setting.

The impact of robotic surgery on a tertiary care colorectal surgery program, an assessment of costs and short term outcomes: A Canadian perspective.

BACKGROUND: Robotic surgery for colorectal pathology has gained interest as it can overcome technical challenges and limitations of traditional laparoscopic surgery. A lack of training and costs have been cited as reasons for limiting its use in Canada. The objective of this paper was to assess the impact of robotic surgery on outcomes and costs in a Canadian setting. METHODS: This is a retrospective study of consecutive patients undergoing left sided colorectal surgery ("Pre-Robotic Phase" n = 145 vs. "Post Robotic Phase" n = 150) and a single tertiary care centre in Ontario, Canada. Utilization and success of minimally invasive surgery (MIS), length of stay, complications and hospital costs were compared. Univariate and Multivariate analysis was used for these comparisons. RESULTS: Characteristics, diagnosis and type of resection were similar between groups. Robotic Implementation resulted in higher rates of successful MIS (i.e. attempt at MIS without conversion) (85% vs. 47%, P < 0.001), shorter mean length of stay (4.7 days vs. 8.4 days, P < 0.001), and similar mean operative times (3.9 h vs. 3.9 h, P = 0.93). Emergency Department visits were fewer in the Robotic Phase (24% vs. 34%, P = 0.04), with no difference in readmission, anastomotic leak or unplanned reoperation. After robotic implementation, the mean total hospital costs decreased, but this was not statistically significant (-$1453, 95% CI -$3974 to +$1068, P = 0.25). Regression analysis, adjusting for age, gender, obesity, ASA and procedure showed similar findings (Robotic Phase -$657, 95% CI -$3038 to +$1724, vs Pre Robotic Phase [Reference], P = 0.59). INTERPRETATION: Implementation of a robotic colorectal surgery program in a Canadian tertiary care centre showed improved clinical outcomes, without a significant increase in the cost of care. Although this study is from a single institution, we have demonstrated that robotic colorectal surgery is feasible and can be cost effective in the right setting.

A framework for role allocation in education, research and leadership services in Canadian academic divisions of general surgery: a modified Delphi consensus.

BACKGROUND: Moving toward a funding standard similar to that for clinical services for roles essential to the functioning of education, research and leadership services within divisions of general surgery is necessary to strengthen divisional resilience. We aimed to identify roles and underlying tasks in these services central to sustainable functioning of Canadian academic divisions of general surgery. METHODS: Between June 2018 and October 2020, we used a 4-step modified Delphi method (online survey, face-to-face nominal group technique [n = 12], semistructured telephone interview [n = 8] and nominal group technique [n = 12]) to achieve national consensus from an expert panel of all 17 heads of academic divisions of general surgery in Canada on the roles and accompanying tasks essential to education, research and leadership services within an academic division of general surgery. We used 70% agreement to determine consensus. RESULTS: The expert panel agreed that a framework for role allocation in education, research and leadership services was relevant and necessary. Consensus was reached for 7 roles within the educational service, 3 roles within the research service and 5 roles within the leadership service. CONCLUSION: Our framework represents a national consensus that defines role standards for education, research and leadership services in Canadian academic divisions of general surgery. The framework can help divisions build resiliency, and enable sustained and deliberate advances in these services.
