Background: Since January 1st of 2005, the situation of bariatric surgery is being analyzed in Germany. The data is registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University Magdeburg. Methods: The data is registered through an online database which includes all information for primary and revision bariatric procedures as well as yearly follow-up. Participation in the quality assurance study is optional. All certificated centers have to participate at the survey. Results: From January 2006 to December 2009, 1478 sleeve gastrectomies (SG) were performed at 45 hospitals. The number of procedures has increased from 126 in 2007 to 933 in 2009. The main complication is leakage of the staple-line. Initial leakage rate was 7% in 2007. Leakage rate dropped down to 2.3% in 2008 and 2.5% in 2009. Mean age of patients was 43.1 years and mean BMI was 52.83 kg/m2. Age and BMI were significantly higher in patients with SG than in all other patients undergoing bariatric surgery. Conclusion: SG is a common and hype bariatric procedure in Germany, but postoperative complication rate is high. Data on the long-term effect of SG on weight loss and amelioration of comorbidities need to be evaluated. More detailed analyzes are necessary to establish the position of SG in the bariatric surgery. Further studies should also include examinations on long-term complications and redo-procedure after SG.
