Abstract

Purpose

Live surgical demonstrations are considered an effective educational tool providing a chance for trainees to observe a real-time decision-making process of expert surgeons. No data exists evaluating the impact of live surgical demonstrations on the outcomes of minimally invasive colorectal surgery. This study evaluates perioperative and short-term postoperative outcomes in patients undergoing minimally invasive colorectal surgery in the setting of live surgical demonstrations.

Methods

Patients undergoing minimally invasive colorectal surgery which was performed as live surgical demonstrations (the study group) performed between 2006 and 2018 were reviewed. These patients were case-matched with those undergoing operations in routine practice (the control group). The study and control group were compared for intraoperative and short-term postoperative outcomes.

Results

Thirty-nine live surgery cases in the study group were case-matched with its thirty-nine counterparts as the control group. Operating time was longer (200 vs 165 min; p = 0.002) and estimated intraoperative blood loss was higher in the study group (100 vs 55 ml; p = 0.008). Patients in the study group stayed longer in the hospital (6 vs 5 days; p = 0.001). While conversion (n = 4 vs n = 1, p = 0.358) and intraoperative complications (n = 6 vs n = 2, p = 0.2) were more frequent in the study group, these outcomes did not reach statistical significance. Overall complications were higher in the study group (n = 22 vs n = 9, p = 0.003). One patient underwent a reoperation due to postoperative bleeding, and one mortality occurred in the live surgery group.

Conclusions

Live surgical demonstrations in minimally invasive colorectal surgery seem to be associated with increased risk of operative morbidity.
