[New data on quality assurance in bariatric surgery in Germany]. / Aktuelle Daten der Qualitätssicherungsstudie für operative Therapie der Adipositas in Deutschland.

ABSTRACT

BACKGROUND: Since January 1st 2005, the situation of bariatric surgery has been examined in Germany. All data are registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at the Otto-von-Guericke University of Magdeburg. METHODS: The voluntary data registration occurs in an internet online data bank. All primary bariatric procedures as well as re- and redo-procedures are documented. Follow-up data were collected once a year. Participation in the quality assurance study is obligatory for certificated centres. RESULTS: Since 2005 13,879 bariatric procedures have been performed at 83 hospitals. The number of primary procedures has increased from 596 in 2005 to 11,835 in 2010. Revisional surgery has been performed in 1,438 patients since 2005. Sleeve gastrectomy (SG) is the major procedure with 1,564 operations in 2010. The mean BMI was 48.8 kg/m². The incidence of comorbidities was 84.8%. CONCLUSION: Bariatric surgery has become more accepted in Germany. Beside the Roux-en-Y gastric bypass, sleeve gastrectomy is the most frequently performed operation. BMI and incidence of comorbidities are still high in comparison with literature values. Due to the lack of evidence, more randomised studies are necessary to standardise operative techniques and evaluate patient selection criteria. Quality assurance studies support a detailed analysis of these parameters.
