Summary
Senior residents can safely perform single-incision laparoscopic colectomy (SLC) with outcomes comparable to experienced surgeons. Residents faced challenges closing the mesenteric margin in left-sided colectomies, indicating a training focus area.
Area of Science:
- Colorectal Surgery
- Minimally Invasive Surgery
- Surgical Education
Background:
- Single-incision laparoscopic colectomy (SLC) is an advanced minimally invasive surgical technique.
- Data on the learning curve and resident acquisition of SLC are currently limited.
Purpose of the Study:
- To evaluate the safety and efficacy of resident-performed SLC compared to staff colorectal surgeons.
- To identify specific procedural challenges during resident training in SLC.
Main Methods:
- Retrospective case-control study of 220 patients undergoing elective colectomy for colon cancer.
- Comparison of outcomes between multiport laparoscopic colectomy (MLC) and SLC performed by residents vs. staff surgeons.
- Video analysis of surgical procedures to measure operative times and identify technical difficulties.
Main Results:
- Residents safely performed SLC with similar oncological and short-term outcomes compared to staff surgeons.
- Operative times were comparable for total colectomies, but varied for right-sided (staff longer) and left-sided (residents longer) procedures.
- Residents required significantly more time for mesenteric margin closure in left-sided colectomies.
Conclusions:
- Senior residents can be trained to safely perform SLC with comparable efficacy to experienced surgeons.
- Mesenteric margin closure in left-sided colectomies presents a key learning challenge for residents.
- Supervised training allows for successful resident acquisition of SLC technique.
