Abstract
Most studies on bariatric surgery outcomes are performed as clinical trials or reflect the clinical experience in single centers The status of bariatric surgery in Germany has been examined since January 1st 2005 with the cooperation of clinics and hospitals at the Institute of Quality Assurance in Surgery at the OttovonGuericke University of Magdeburg GermanyIn this prospective multicenter observational study the data obtained for all primary bariatric procedures including all repeated operations performed on consecutive patients with morbid obesity at participating hospitals from 2005 to 2007 were prospectively collected using an Internet online data registry In particular perioperative characteristics such as the spectrum of diagnostic measurements type of surgical procedures and short and longterm outcomes were investigatedDuring the study period 629 surgical procedures were performed at 21 hospitals in 2005 828 procedures at 32 hospitals in 2006 and 1666 procedures at 35 hospitals in 2007 In 2005 and 2006 gastric banding was the most frequently performed operation followed by the RouxenY gastric bypass RYGBP In 2007 a RYGBP was carried out in 421 of all bariatric procedures Among all patients 744 were female The mean body mass index BMI was 485 kg/m2 in 2005 484 kg/m2 in 2006 and 480 kg/m2 in 2007 Followup data after 12 months were available for 638 of the patients in 2005 and 2006 these data showed greater reduction of BMI after malabsorptive rather than restrictive bariatric procedures The mortality was 01 30 days and 016 overallAs indicated by the worldwide trend there is an ongoing change from restrictive bariatric procedures to malabsorptive procedures and sleeve gastrectomy Although the BMIs of German patients undergoing bariatric surgery appear to be substantially higher than those of patients from most other countries there were no differences in intraoperative and shortterm complications or in overall outcomes during followup when compared with published studies
