Summary
Robotic sleeve gastrectomy (RSG) is as safe as laparoscopic sleeve gastrectomy (LSG) within 30 days, with similar complication rates. RSG has a slightly longer operative time but it is not clinically significant.
Area of Science:
- Bariatric surgery
- Minimally invasive surgery
- Surgical outcomes
Background:
- Robotic sleeve gastrectomy (RSG) is gaining popularity in bariatric surgery.
- The comparative safety of RSG versus laparoscopic sleeve gastrectomy (LSG) requires further investigation.
Purpose of the Study:
- To compare the 30-day safety and complication rates of robotic sleeve gastrectomy (RSG) and laparoscopic sleeve gastrectomy (LSG).
Main Methods:
- Retrospective review of 927 patients (575 RSG, 352 LSG) from June 2021 to August 2023.
- Comparison of baseline and operative characteristics using statistical tests.
- 30-day complication rates analyzed using multivariable logistic regression, adjusted for key factors.
Main Results:
- No significant difference in 30-day complication rates between RSG and LSG (3.5% in both groups).
- RSG had a median operative time of 73 minutes compared to 66 minutes for LSG (p=0.0002).
- No learning curve effect on complications was observed for RSG.
Conclusions:
- Robotic sleeve gastrectomy (RSG) demonstrates comparable safety to laparoscopic sleeve gastrectomy (LSG) within 30 days post-operation.
- The slightly increased operative time for RSG is not considered clinically significant.
- RSG is a safe alternative to LSG for bariatric procedures.
