title: Single-anastomosis duodenoileal bypass with sleeve gastrectomy: metabolic improvement and weight loss in first 100 patients.
abstract: BACKGROUND
  Single-anastomosis duodenoileal bypass with sleeve gastrectomy is a simplified 1-loop duodenal switch with a 200-250 common channel. Our objective was to analyze the weight loss and metabolic results of the technique on a series of 100 consecutively operated patients at a tertiary center university hospital.
  
  
  METHODS
  A total of 100 patients consecutively underwent surgery. The criteria of inclusion were morbid obesity or metabolic disease. In the first 50 cases, the common/efferent limb measured 200 cm. The length was changed to 250 cm to reduce the hypoproteinemia rate.
  
  
  RESULTS
  No mortality and no severe complications developed. The mean excess weight loss was >95% maintained during the follow-up period. More than 90% of the patients experimented complete remission of type 2 diabetes mellitus. Two conversions to a standard duodenal switch with a longer alimentary channel were required because of recurrent hypoproteinemia. Hypertension was controlled in 98% of the patients, with a 58% remission rate. The mean number of bowel movements was 2.5/d.
  
  
  CONCLUSIONS
  Single-anastomosis duodenoileal bypass with sleeve gastrectomy is a simplified duodenal switch procedure that is safe and quicker to perform and offers good results for the treatment of both morbid obesity and its metabolic complications.
