    BackgroundLaparoscopic sleeve gastrectomy is gaining popularity in the US; however, there has been no study examining the use of sleeve gastrectomy at a national level and its impact on the use of other bariatric operations. The aim of this study was to examine contemporary changes in use and outcomes of bariatric surgery performed at academic medical centers.MethodsUsing ICD-9 diagnosis and procedure codes, clinical data obtained from the University HealthSystem Consortium database for all bariatric procedures performed for the treatment of morbid obesity between October 1, 2008 and September 30, 2012 were reviewed. Quartile trends in use for the 3 most commonly performed bariatric operations were examined, and a comparison of perioperative outcomes between procedures was performed within a subset of patients with minor severity of illness.ResultsA total of 60,738 bariatric procedures were examined. In 2008, the makeup of bariatric surgery consisted primarily of gastric bypass (66.8% laparoscopic, 8.6% open), followed by laparoscopic gastric banding (23.8%). In 2012, there was a precipitous increase in use of laparoscopic sleeve gastrectomy (36.3 %), with a concurrent reduction in the use of laparoscopic (56.4%) and open (3.2%) gastric bypass, and a major reduction in laparoscopic gastric banding (4.1%). The length of hospital stay, in-hospital morbidity and mortality, and costs for laparoscopic sleeve gastrectomy were found to be between those of laparoscopic gastric banding and laparoscopic gastric bypass.ConclusionsWithin the context of academic medical centers, there has been a recent change in the makeup of bariatric surgery. There has been an increase in the use of laparoscopic sleeve gastrectomy, which has had an impact primarily on reducing the use of laparoscopic adjustable gastric banding.Copyright © 2013 American College of Surgeons.
