Revisional surgery is required in a significant number of patients because of failure to lose weight, loss of quality of life, weight regain, or complications of the previous procedure. It has traditionally been associated with higher complication rates, and there appears to be no standardized surgical approach to revisional surgery. The aim of the study was to review the revisional procedures performed at St George Private Hospital and analyze the outcomes of the different types of revisional surgery.


We performed a retrospective review of 75 patients who underwent revisional surgery between December 2003 and October 2007. Demographic, anthropometric, perioperative, and clinical follow-up data were collected, and statistical analyses were performed using SPSS version 14.0.


Sixty-six of the 75 patients were female. The mean age at the time of revision was 46.32 (22-68) years. Mean initial weight was 119.08 kg, and body mass index (BMI) was 43.42 kg/m(2). The lowest BMI and excess weight loss (EWL) recorded after primary surgery was 36.9% and 53.5%, respectively. At the time of revision, the mean EWL was 24.79. The EWL at 3 months and 6 months were 41.7% and 47.8%, respectively. Revision was performed laparoscopically in 51 patients and via laparotomy in 24 patients. There was no mortality in the cohort, but there were 17.3% minor and 4.0% major perioperative morbidities.


Our study suggests that revision can be performed safely. Weight loss is satisfactory, and complications of the previous operations were all reversed. Furthermore, revisions may be done laparoscopically, including those who had previous open procedures.
