Summary
Surgical residents preferred intracorporeal knot tying and found the Endo Stitch instrument significantly faster and easier for laparoscopic suturing and knot tying compared to conventional methods.
Area of Science:
- Minimally Invasive Surgery
- Surgical Education
Background:
- Laparoscopic suturing is a core skill in advanced laparoscopic surgery training.
- Evaluating different knot-tying and suturing techniques is crucial for resident education.
Purpose of the Study:
- To compare intracorporeal and extracorporeal knot-tying techniques.
- To assess resident performance and preference for conventional instruments, Endo Stitch, and Suture Assistant in laparoscopic suturing and knot tying.
Main Methods:
- 39 residents performed laparoscopic knot tying exercises on a trainer model.
- 43 residents performed laparoscopic suturing exercises using three different instruments.
- Key endpoints included execution time and subjective resident preference.
Main Results:
- The intracorporeal knot-tying technique was preferred by 89% of residents.
- Laparoscopic suturing time was significantly shorter with the Endo Stitch (114s) versus conventional (206s) or Suture Assistant (151s).
- Residents preferred the Endo Stitch for suturing, knot tying, and overall handling.
Conclusions:
- The Endo Stitch instrument demonstrably enhances laparoscopic skills.
- It emerged as the preferred device for both laparoscopic knot tying and suturing among surgical residents.
