OBJECTIVES: Buttress material, either absorbable or permanent, is widely used in bariatric surgery. The aim of this research was to assess differences in clinical and economic outcomes associated with the use of staple line buttress in inpatient Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) surgical procedures. METHODS: Data from the Premier Perspective DatabaseTM from January 2006 to March 2014 were analyzed. Adult patients undergoing single primary SG or RYGB procedures were identified using ICD-9 codes. A keyword-based algorithm was used to identify buttress use. Assessed outcomes variables were length of stay (LOS), 30-day readmission rate, occurrence of significant bleeding (≥3units of transfusion blood product) and total cost to hospital. Differences between the buttress and non-buttress groups were evaluated using multivariate regression models for readmissions, LOS and total cost. Input variables for the regression models were buttress use, surgical characteristics, patient characteristics, patient comorbidities and hospital characteristics. RESULTS:
