Abstract
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become a dominant bariatric procedure. In the past, significant leak rates prompted the search for staple line reinforcement (SLR) techniques. Previous analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database for all LSG suggested a detrimental influence of SLR on leak rates and overall morbidity. OBJECTIVE: To investigate the relationship between various SLR techniques and bougie size with 30-day outcomes. SETTING: Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program-accredited bariatric surgery hospitals. METHODS: Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 to 2016 Participant Use File data, primary LSG cases were divided into study groups based on surgical techniques. All variables were reported in the Participant Use File except leak rate and overall morbidity, which had to be derived. Multiple bivariate analyses were used to analyze the 30-day outcomes. RESULTS: A total of 198,339 primary LSG operations were included and grouped into No SLR (23.0%), SLR (54.2%), oversewn staple line (9.5%), and a combination of SLR + oversewn staple line (13.3%). There were no statistical differences between study groups in mortality, overall morbidity, or leak rate. Bleeding and reoperation rates were statistically higher in the No SLR group. Bougie size was not associated with change in leak rates. CONCLUSION: Primary LSG is a safe procedure with low morbidity and mortality rates. SLR is associated with decreased rates of bleeding and reoperations but does not affect leak rates. The selection of SLR technique should be left to the surgeon's discretion with an understanding of the associated risks, benefits, and costs.
