The purpose of our study was to determine whether or not the results of LGB have been realized in the general US population. We used data from the nationwide inpatient sample to define differences in outcomes after LGB versus open techniques (OGB). We calculated hospital stay, in-hospital mortality, and major complications for both OGB and LGB. We noted a total of 26,940 gastric bypass procedures: LGB was coded in 16.3% and OGB in 83.7%. The mean hospital stay, mortality, wound, gastrointestinal, pulmonary, and cardiovascular complications were significantly lower after LGB (P<0.001). After we adjusted for covariates, hospital stay, pulmonary morbidity, and mortality remained significantly lower after LGB (P<0.001). In conclusion, LGB is associated with significantly lower mean hospital stay and with reduced morbidity and mortality as compared with OGB. © 2006 Lippincott Williams & Wilkins, Inc.
