Technical proficiency assessment of robotic intracorporeal single-stapling colorectal anastomosis using video-based RA-CUSUM.

ABSTRACT:

Background

This study aimed to evaluate the learning curve of robotic intracorporeal single-stapling anastomosis (RiSSA) using risk-adjusted cumulative sum (RA-CUSUM) analysis based on standardized procedural intervals.

Methods

We retrospectively analyzed 36 consecutive patients who underwent robotic left-sided colorectal resection with RiSSA by a single surgeon. Eight intraoperative timepoints were annotated from surgical videos to define two composite metrics: pure RiSSA interval and total purse-string suture time. RA-CUSUM analysis was applied to assess technical proficiency over time.

Results

The RA-CUSUM curve showed an inflection point at case 17 for the pure RiSSA interval and at case 11 for purse-string suture time, indicating earlier acquisition of suture ski
