"Conclusions: The completely Laparoscopic Biliopancreatic Diversion with Duodenal Switch is a safe, feasible and very effective operation for patients with BMI’s in the 60’s and above, and should be offered to these patients by those surgeons well-trained and comfortable with its performance. A single-stage Laparoscopic BPD/DS can be performed in patients with BMI’s > 60 with a very low morbidity and mortality."
