BACKGROUND: This study presents late results of a previously published 2-year prospective comparison between Roux-en-Y gastric bypass (RYGBP) versus biliopancreatic diversion with Roux-en-Y gastric bypass (BPD-RYGBP) in an exclusively non-superobese population.
METHODS: From a cohort of 130 patients with a BMI of 35-50 kg/m(2), 65 were randomly selected to undergo RYGBP and 65 to BPD-RYGBP. All underwent follow-up evaluation at 1, 3, 6, and 12 months postoperatively and every year thereafter.
RESULTS: Follow-up at the eighth year was achieved in 60% of the BPD-RYGBP and in 58% of the RYGBP group (p = 1.00). Mean excess weight loss (EWL%), was significantly higher following BPD-RYGBP (76.89 ± 1.53) as compared to RYGBP (67.17 ± 1.43) (p = 0.0004). The mean success rate (percentage of patients with EWL% ≥50%) was significantly higher after BPD-RYGBP (95.85 ± 1.01) than RYGBP (75.91 ± 3.58) (p = 0.0001). No significant differences were observed for late non-metabolic complications. The incidence of anemia, iron deficiency, B12 deficiency, and low-ferritin levels was relatively high in both groups with not always significant differences. Severe protein malnutrition occurred in four patients (three BPD-RYGBP and one RYGBP) (p = 0.37). In only one BPD-RYGBP patient (1.54%) was revision surgery to RYGBP necessary, due to recurrent episodes of hypoproteinemia. The remaining patients were treated successfully with total parenteral nutrition and nutritional counseling.
CONCLUSIONS: Late results presented in this paper agree with the previously published 2-year results of the same patient cohort. Although both procedures are safe and effective, BPD-RYGBP seems to prevail in terms of successful weight loss without a significantly higher incidence of metabolic and non-metabolic complications.
