Summary
Single-port laparoscopic cholecystectomy is feasible, with operative times significantly improving after the first ten cases. This suggests a learning curve of approximately ten procedures for fellowship-trained surgeons.
Area of Science:
- Minimally Invasive Surgery
- Surgical Technique
- Gastrointestinal Surgery
Background:
- Single-port laparoscopic surgery is gaining acceptance in clinical practice.
- This study evaluates surgeon experience with single-port laparoscopic cholecystectomy.
- Operative time is used to assess the learning curve for this procedure.
Purpose of the Study:
- To describe a surgeon's experience with single-port laparoscopic cholecystectomy.
- To delineate the learning curve for single-port laparoscopic cholecystectomy.
- To assess the impact of surgeon experience on operative time and technical facility.
Main Methods:
- A 2-cm transumbilical incision was used with three 5-mm ports.
- Specialized retraction techniques were employed for gallbladder manipulation.
- Data on patient demographics, operative time, length of stay, pathology, and complications were collected.
Main Results:
- 52 of 54 patients (96.3%) successfully underwent the procedure.
- Mean operative time was 80 minutes, with a length of stay of 0.3 days.
- Operative times significantly decreased after the initial 10 cases (p=0.0001).
Conclusions:
- The learning curve for single-port cholecystectomy is approximately 10 cases for fellowship-trained surgeons.
- Significant improvement in operative times indicates increasing technical proficiency.
- The procedure demonstrates a favorable learning curve and potential for widespread adoption.
