The Swedish Adjustable Gastric Banding (SAGB) for morbid obesity — Weight loss, complications, pouch volume, and stoma diameter in a four-year follow-up

Background: We have developed an adjustable gastric band in which the stoma diameter can be adjusted from the outside. The aim of this study was to evaluate the new standardized operating technique with our band in terms of weight loss and complication rate. Another aim of this study was to investigate the changes in pouch volume with time and the relationship between pouch volume and stoma diameter, and subsequent weight loss following the placement of the Swedish Adjustable Gastric Band (SAGB).
