Vertical Banded Gastroplasty Converted to Roux-en-Y Gastric Bypass Had Little Impact on Nutritional Status After 5-year Follow-up Conversion to a Roux-en-Y gastric bypass (RYGBP) has been advocated after the failure of vertical banded gastroplasty (VBG). The aim of this study was to analyze the differences in anthropometric and nutritional parameters between patients with VBG and those converted to RYGBP. Method 45 patients initially underwent VBG. 22 of these patients have maintained this operation for more than 5 years (Group A) and 23 have been converted to RYGBP (Group B), after 2 years of follow-up. We analyzed anthropometric and nutritional parameters (macronutrients, micronutrients and lipid profile), and post-operative morbidity after both procedures. Data were recorded before the first operation and at 6 months, 1, 2 and 5 years follow-up. Results VBG failure rate was 51%. The 23 patients converted to RYGBP have maintained an excess weight loss (EWL) of 70% 3 years after the revision, and all the complications related to VBG disappeared. Anthropometric parameters were significantly better after RYGBP. We found no significant differences in nutritional status between both groups except for levels of iron, vitamin B(12) and transferrin saturation index, which significantly decreased in converted patients. The redo procedure had a low morbidity rate, with no mortality. Conclusion More than 50% of VBGs failed after 2-year follow-up. Patients converted to RYGBP maintained mean EWL 73% at 5 years. The only significant nutritional deficiencies were iron and vitamin B(12), in patients converted to RYGBP. Authors: Source: Stomach Bypass Surgery Information |
