BACKGROUND: Morbid @entity28 (Basic Mass Index  >=   40  kg/m(2)) leads to increased long-term mortality after @entity14 ( @entity14 ) surgery. Little is known about its effects on peri-operative @entity14 surgery outcomes. METHODS: 85,300 discharges for @entity14 surgery were identified using the redesigned 2012 National Inpatient Sample. Outcomes of interest were mortality, healthcare charges, and surgical outcomes in morbidly  @entity28 @entity1 which were compared to those in nonobese @entity1 . RESULTS: There were 4385 (5.14%) morbidly @entity28 @entity1 who underwent @entity14 surgery during the study period. Morbid @entity28 was associated with younger age, females, and African Americans in our study (p  <  0.05). Morbidly @entity28 @entity1 had higher prevalence of @entity14 peri-operative co-morbidities, surgical complications, and conversions from laparoscopic to open surgery. On multivariate analysis, morbid @entity28 led to an increased @entity14 surgery peri-operative mortality (OR 1.85, 95  % CI 1.15, 2.97). Mortality remained significant even after adjusting for surgical complications (OR 1.79, 95  % CI 1.12, 2.88). Morbidly @entity28 @entity1 undergoing @entity14 also had a prolonged length of hospitalization (1.22  day, 95  % CI 0.67, 1.78), a  15,582 increase in total hospital charges (95  % CI 8419, 22,745), and increased disposition to short-term rehabilitation facilities (OR 2.25, 95  % CI 1.79, 2.84). CONCLUSION: Analysis of national level data demonstrates that morbidly @entity28 @entity1 have an increased @entity14 surgery peri-operative mortality with higher prevalence of co-morbidities, surgical complications, and more health care resource utilization. Future research efforts should concentrate on ameliorating these outcomes in morbidly @entity28 @entity1 .
