Outcome of laparoscopic adjustable gastric banding and prevalence of band revision and explantation at academic centers: 2007-2009

Abstract

Background: Laparoscopic adjustable gastric banding is gaining in popularity in the United States. Our objective was to examine the outcomes of laparoscopic adjustable gastric banding and the prevalence of band revision and explantation at academic medical centers.

Methods: Using the "International Classification of Diseases, 9th revision," diagnosis and procedure codes, data were obtained from the University Health System Consortium Clinical Database for all laparoscopic adjustable gastric banding procedures performed from 2006 to 2009. The outcome measures included demographics, length of hospital stay, perioperative morbidity, mortality, and the prevalence of band revision and explantation.

Results: A total of 10,151 laparoscopic gastric banding procedures were performed from January 2007 to December 2009. The mean length of stay was 1.2 days. The perioperative morbidity rate was 3.0%, and the in-hospital mortality rate was .03%. The prevalence of band revision was .76% and of band explantation was .87%. Compared with the outcome of primary gastric banding, gastric band revision or explantation was associated with a longer length of hospital stay, greater perioperative morbidity, and greater cost.

Conclusion: Within the context of the 3-year period of analysis, laparoscopic gastric banding was associated with low perioperative morbidity and mortality and a low prevalence of band revision and explantation.
