Background:
Sleeve gastrectomy (SG) remains a safe and effective treatment for severe obesity. The number of robotic SG (RSG) has steadily increased from 2015 to 2021. Prior studies have shown higher rates of some adverse outcomes with RSG but have not accounted for staplers used.
Objective:
The aim of this study is to compare outcomes for RSG compared to laparoscopic sleeve gastrectomy (LSG), accounting for stapler type used.
Setting:
National hospital derived administrative data.
Methods:
The PINC AI Healthcare Database was used for the current study. Analyzed cohort included elective LSG or RSG performed between January 1, 2019, and December 31, 2021. Patient, hospital, billing, provider, insurance, and operative data were captured. Bleeding, leak, and other outcomes were identified by ICD-10-CM diagnosis codes. Propensity score matching (PSM) compared outcomes between RSG with SureForm stapler vs. LSG with powered stapler.
Results:
56,013 LSG and 13,832 RSG were analyzed. RSG increased from 15 % in 2019 to 25 % in 2021 with an absolute 27 % increase in robotic stapler utilization for RSG. PSM analysis compared, 5434 RSG with SureForm Stapler vs. 5434 LSG with powered staplers showed equivalent complication rates, shorter LOS, but longer operative time with RSG.
Conclusions:
When stapler type used is accounted for, patient outcomes following RSG and LSG are equivalent.
