Predictors and outcomes of bleed after sleeve gastrectomy: an analysis of the MBSAQIP data registry.

Bleeding after laparoscopic sleeve gastrectomy (LSG) is an important complication associated with significant morbidity and a drastic increase in healthcare resources. Multiple strategies have been developed to minimize bleeding, including varying bougie size, line reinforcement, and intra-operative tranexamic acid. These techniques, however, have been implemented without a clear understanding of the pre-, intra-, and postoperative predictors of bleeding in patients undergoing SG. The purpose of this study was to examine predictors and outcomes associated with postoperative bleeding in patients undergoing LSG. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement data registry. We identified Metabolic and Bariatric Surgery Accreditation and Quality Improvement patients who underwent LSG in 2015 and 2016. Primary outcomes of interest include identifying the prevalence, impact, and predictors of bleeding in LSG patients. Our secondary outcomes of interest include characterizing overall complication rates in LSG patients. Univariate analysis of pre-, intra-, and postoperative variables was performed using Χ A total of 175,353 patients underwent LSG from 2015 to 2016. The majority of patients were female (79.0%), with a mean age of 44.4 ± 12.0 years and a mean body mass index of 45.2 kg/m Bleeding after LSG is associated with increased complications, readmission and reoperation rates, and mortality at 30 days. Staple-line reinforcement techniques independently predict a lower risk of postoperative bleeding after LSG. Adoption of these techniques may therefore have an important role in reducing morbidity and mortality for patients who undergo LSG.
