Background: Pathologic late pouch dilation is the most frequent complication following gastric banding procedures for morbid obesity. In this study, possible predictive factors were sought. The treatment of these complications and the final outcome are discussed. Methods: Between December 1994 and December 1997, 171 patients underwent laparoscopic adjustable banding for morbid obesity. 40 patients underwent classic gastric banding (Group 1), and 131 patients underwent esophagogastric banding (Group 2). Results: Pouch dilation developed in 6 patients (15%) in Group 1 and 12 patients (9.2%) in Group 2. There were no significant predictive factors, although the complication occurred more frequently in patients with presurgical hiatus hernia. The type of dilation was different for each group, as was the surgical treatment. Laparoscopic repositioning of the band was always possible and was uncomplicated. The long-term outcome has been good, and weight loss has been maintained. Conclusions: A frequent complication following banding procedures for morbid obesity is pathologic late pouch dilation. In experienced hands, when appropriate surgical treatment is carried out, this is not a major problem. Nevertheless, efforts should be made to decrease the number of late dilations.
