Robot-assisted distal gastrectomy (RADG) is feasible for surgeons experienced in open surgery. A single surgeon demonstrated a learning curve of approximately 25 cases, achieving safe and effective outcomes in distal gastrectomy.
Area of Science:
- Surgical Oncology
- Robotic Surgery
- Gastrointestinal Surgery
Background:
- Robot-assisted distal gastrectomy (RADG) offers potential benefits in minimally invasive surgery.
- Surgeons experienced in open gastrectomy may face a learning curve transitioning to robotic procedures.
Purpose of the Study:
- To evaluate the learning curve and short-term surgical outcomes of RADG performed by a surgeon proficient in open gastrectomy but new to laparoscopic techniques.
- To determine the feasibility of RADG without prior extensive laparoscopic experience.
Main Methods:
- Sixty RADG procedures were performed by a single surgeon using the da Vinci Surgical System.
- Patient data, surgical parameters, and postoperative outcomes were analyzed.
- Cases were divided into early (n=25) and later (n=35) groups based on the learning curve.
Main Results:
- The learning curve for RADG was overcome after approximately 25 cases, indicated by stabilized surgery duration.
- Mean surgery duration decreased significantly from 420.8 minutes (early) to 281.7 minutes (later) (P<0.001).
- Console time also significantly decreased, while blood loss and other postoperative outcomes showed no significant differences between groups.
Conclusions:
- Robot-assisted distal gastrectomy can be safely performed by surgeons experienced in open gastrectomy.
- Acceptable short-term surgical outcomes are achievable after mastering the learning curve.
