The laparoscopic adjustable gastric band (LAGB) has previously been classified as a restrictive procedure; physically limiting meal size. Recently, the key mechanism has been hypothesized to be the induction of satiety without restriction. Effects can be controlled by modifying LAGB volume, possibly as a result of effects on gastric emptying or transit through the LAGB. Successful LAGB patients underwent paired, double blinded, esophageal transit and gastric emptying scintigraphic studies; with the LAGB at optimal volume and near empty. A new technique allowed assessment of emptying and transit through the infra- and supraband compartments.
