Long-Term Results of Vertical Banded Gastroplasty: Marlex versus Dacron Banding

Background: The VBG was originally performed with a Marlex band and characterized by a satisfactory weight loss and low morbidity. The effect of the material used for the banding procedure (Marlex vs Dacron) in vertical banded gastroplasty (VBG) is evaluated. Methods: In 49 consecutive obese patients treated with a VBG, a Marlex band was used in 17 patients and a Dacron band in 32 patients. Data were analyzed retrospectively with regard to the type of band, weight loss and complications. Results: A significant difference was found in the percentage excess weight 5 years postoperatively in favor of the Dacron group (59.2% vs 39.2%; p < 0.05) because of more band-related complications in the Marlex group. The difference in percentage excess weight disappeared 8 years postoperatively (43.3% vs 46.8%), due to the renewed weight loss of the Marlex group following reoperation. Conclusion: The Dacron band is superior to the Marlex band in VBG because sustained weight loss is satisfactory and morbidity is low.
