Abstract

Purpose

Video review is a reliable method for surgical education in laparoscopic gastrectomy (LG), but more objective methods are still needed. The purpose of this study was to determine whether the energy device records reflected surgical competency, and thereby may improve surgical education.

Methods

A total of 16 patients who underwent LG for gastric cancer using the Thunderbeat® device were preliminarily retrospectively analyzed. This device has the function of ‘intelligent tissue monitoring’ (ITM), a safety assist system stopping energy output, and can record ITM detections and firing time during surgery. The number of ITM detections and firings, and the total firing time during gastrocolic ligament dissection and infrapyloric dissection were compared between trainees (n = 9 by 5 surgeons) and experts (n = 7 by 5 surgeons). The non-edited videos (n = 16) were scored, and the correlations between the scores and the records were then analyzed.

Results

Significantly more ITM detections, firings, and a longer total firing time were observed in trainees than in experts. The number of ITM detections and firing had negative correlations with the scores of the operation speed, the use of the non-dominant hand, and the use of an energy device.

Conclusions

Our preliminary study suggested that the above described energy device records reflected surgical competency, and thereby may improve surgical education.
