Background: The VBG was originally performed with a Marlex band and ch
aracterized by a satisfactory weight loss and low morbidity. The effec
t of the material used for the banding procedure (Marlex vs Dacron) in
vertical banded gastroplasty (VBG) is evaluated. Methods: In 49 conse
cutive obese patients treated with a VBG, a Marlex band was used in 17
patients and a Dacron band in 32 patients, Data were analyzed retrosp
ectively with regard to the type of band, weight loss and complication
s. Results: A significant difference was found in the percentage exces
s weight 5 years postoperatively in favor of the Dacron group (59.2% v
s 39,2%; p < 0.05) because of more band-related complications in the M
arlex 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 i
s satisfactory and morbidity is low.
