A recent systematic review reported wide-ranging long-term revision or reversal rates after laparoscopic adjustable gastric banding (LAGB) of between 8% and 60%.1 The marked variability is likely due to different definitions of revisional surgery, different follow-up durations, and the different “eras” of the surgical cohorts. The studies reviewed provided little detail regarding the types of revisional procedures performed.1 Two recent studies1,2 have significantly advanced evidence in this area. The Longitudinal Assessment of Bariatric Surgery2 in the United States reported that of 610 patients undergoing LAGB, the rate of revisional surgery was 17.5 events per 100 patients over 3 years, primarily for band removal, revision to another bariatric procedure, or port revision. O’Brien et al1 reported that of 1370 patients undergoing LAGB at an Australian bariatric center, the rate of revisional surgery was 15.3 events per 100 patients over 3 years, primarily for repositioning of the gastric band or port revisions. The present study reports revisional surgery rates for the national population of Australians undergoing LAGB between July 1, 2005, and June 30, 2006.
