Comparison of Biliopancreatic Diversion Bypass (BPD) and Duodenal Switch (BPD/DS) A reduction of 70% of excess body weight can be achieved after BPD, but there is a risk of malnutrition and diarrhea. This risk may be reduced by pyloric preservation with Duodenal Switch. Method BPD was performed until 1999, when Duodenal Switch was introduced, both with a common channel of 50 cm. At their latest clinic visit, patients filled in a questionnaire regarding weight loss, dietary history, gastrointestinal symptoms, obesity-related comorbidity, and medication including dietary supplements and underwent a serum nutritional screen. Results BPD was performed in 73 patients and Duodenal Switch in 61 patients, with a median preoperative body mass index (BMI) of 44.8 kg/m and a median follow-up of 28 months. There were no significant differences between BPD and Duodenal Switch with regards to age, sex, BMI, or morbidity. Median excess weight loss and BMI at 12, 24, and 36 months was 64.1, 71.0, and 72.1% and 33.1, 31.5, and 31.5 kg/m, respectively; there were no significant differences between BPD and Duodenal Switch. There were no significant differences between BPD and Duodenal Switch with regards to meal size, fat score, nausea, vomiting, diarrhea, or nutritional parameters. However, 18% of patients were hypoalbuminemic, 32% anemic, 25% hypocalcemic, and almost half had low vitamin A, D, and K levels, despite more than 80% taking vitamin supplementation. Conclusion Duodenal Switch does not improve weight loss or lessen the gastrointestinal or nutritional side effects of BPD. Authors: Source: Gastric Bypass Surgery Information |
