title: [Treating morbid obesity with laparoscopic  biliopancreatic diversion with duodenal switch].
abstract: BACKGROUND
  Biliopancreatic diversion with duodenal switch is used in the treatment of morbid obesity. Few centres perform the procedure laparoscopically. We aimed to evaluate the perioperative outcomes and weight loss after laparoscopic duodenal switch.
  
  
  METHODS
  All patients operated with biliopancreatic diversion with duodenal switch at the Centre for Morbid Obesity at Oslo University Hospital (2004-2009) were included. The perioperative period was defined as within 30 days of surgery.
  
  
  RESULTS
  A total of 48 patients were operated, all laparoscopically. Median preoperative BMI was 54 kg/m2 (range 41-88), and 33 patients (69 %) were women. Ten patients (21 %) were operated in two steps: first gastric sleeve and later duodenal switch. Median operation time was 200 minutes (100-658). Twelve patients (25 %) had complications, four (8 %) were reoperated, and one died. Median postoperative hospital stay was three (1-56) days. After two years, median BMI was 32 kg/m2 (24-45), median weight loss 39 % (22-60) and median excess BMI (> 25 kg/m2) loss 73 % (43-106).
  
  
  CONCLUSIONS
  Duodenal switch was applied in a minority of patients operated for morbid obesity. The procedure can be performed laparoscopically with a short hospital stay and leads to a substantial weight loss. Perioperative morbidity was high and was comparable to the results from other series.
