title: [Operative technique and outcome in metabolic surgery: conventional and banded gastric bypass].
abstract: BACKGROUND
  The prevalence of morbid obesity and its sequelae is increasing in Germany, Europe and worldwide. Bariatric surgery is thus gaining in importance for the treatment of patients with malignant obesity. Creation of a gastric bypass is one of the most frequently performed procedures for obesity.
  
  
  CONCLUSIONS
  The gastric bypass has been used -since 1966 as a surgical means of weight reduction in obese patients. In the mean time various modifications have been developed. Thus, for example, the laparoscopic procedure represents the current standard. After the operation most patients experience an excess weight loss (EWL) of between 61 and 83 %. The comorbidities of obesity are also markedly improved and in a high percentage even cured after the operation. It is worthy of note that diabetes mellitus type II improves shortly after the operation even before any weight loss has occurred. The suggests that the operation induces more than "just" a loss of weight.
  
  
  CONCLUSIONS
  For decades the gastric bypass has been a well known standard operation of overweight and, in addition to the reduction in weight, is also a therapy for diabetes mellitus -type II.
