Background: This was a retrospective study, performed 10 years after surgery, to compare the results between biliopancreatic diversion (BPD) with distal gastrectomy (DG) versus BPD with duodenal switch (DS). Methods: Complete follow-up data were available for 96% of patients, allowing a comparison of weight loss. revision. side effects, and complications at 10 years. Results: After BPD-DS. weight loss was 25% greater than after BPD-DG (46.8 +/- 21.7 kg versus 37.5 +/- 22 kg, respectively P < .0001). The need for revision decreased from 18.5% to 2.7% (P < .0001), and the prevalence of vomiting during the previous month was 50% less (23.7-50.6%, P < .0001) after BPD-DS compared with after BPD-DG. Late complications were the same for both procedures. Blood analysis showed that, after BPD-DS, the levels of calcium, iron, and hemoglobin were significantly greater and the parathyroid hormone level was lower than after BPD-DG (71.3 +/- 44.2 versus 103.0 +/- 64.0 ng/L, respectively: P < .0001). Conclusion: The DS greatly improved the BPD, as it wits initially proposed. The use of the DS increased weight loss, decreased the need for revision, resulted in fewer side effects, and improved the absorption of nutrients. (Surg Obes Relat Dis 2009;5:43-47.)
