Abstract

BACKGROUND: Sleeve gastrectomy (SG) is the most popular bariatric procedure in the United States. Although standardized, variation exists in how the staple line is managed. Robotic approaches to SG (RSG) are increasing, though benefits compared with the conventional laparoscopic approach (LSG) remain controversial. OBJECTIVE: Evaluate the safety of RSG versus LSG using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry, controlling for variation in staple-line management. SETTING: University health network, United States. METHODS: SG cases from January 1 to December 31, 2016, in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry were included. Demographic characteristics and 30-day outcomes were analyzed with separate Mann-Whitney rank sums tests, χ tests, or Fisher's exact tests, with P < .05 denoting statistical significance. Multivariate regression analysis was performed to control for method of staple-line treatment. RESULTS: Of the 107,726 patients who underwent SG, 7385 were RSG. Treatment of the staple line was associated with a significantly lower rate of bleeding, with odds ratios of .69 and .58 for staple-line reinforcement alone and staple-line reinforcement plus oversewing, respectively. Multivariate analysis revealed RSG had a higher rate of organ space infection than LSG (odds ratio 2.07). Otherwise, RSG did not significantly differ from LSG save for a longer median operative time (89 versus 63 min, respectively, P < .0001). CONCLUSIONS: RSG is a growing alternative to the conventional laparoscopic approach. According to the 2016 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, the RSG carries a higher risk of organ space infection. The reasons behind this finding require further study.
