Although adjustable gastric banding shows good results concerning weight loss, several complications such as excessive vomiting, total dysphagia, and slipping of the stomach through the band with pouch dilatation may occur rather frequently. Different types of adjustable bands are available to prevent these short- and mid-term complications.In this retrospective study, 120 consecutive laparoscopic adjustable gastric bandings were performed. In group I, 50 patients were treated with adjustable silicone gastric banding (ASGB) by an intragastric balloon calibration technique. Group II (n = 29) received the same band by a surgical technique with tunneling behind the esophagus toward the angle of His. Group III (n = 41) received Swedish adjustable gastric banding (SAGB) by the same technique as in Group II.Weight loss was approximately 15% of the excess weight after 3 months, 30% after 6 months, and 45% after 12 months in all groups. Total dysphagia was significantly more frequent in Groups I and II. The incidence of slipping of the band and pouch dilatation was more frequent in Group II.The diameter of the ASGB band is rather small and can cause total dysphagia independently of surgical technique. The SAGB is easy to perform and seems less vulnerable to complications like dysphagia and slipping of the band, probably because of the individual adjustment of the stoma diameter during surgery and good fixation of both band and ventral pouch with separate posterolateral sutures.
