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 with the cooperation of clinics and hospitals at the Institute of Quality Assurance in Surgery at the Ottovon-Guericke University of Magdeburg (Germany) since January 1, 2005.
In 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. Perioperative characteristics such as the spectrum of diagnostic measurements, type of surgical procedures, and short- and long-term outcomes were investigated.
During the study period 3,123 surgical procedures were performed. In 2005 and 2006, gastric banding (GB) was the operation performed most frequently, followed by the Roux-en-Y gastric bypass (RYGBP). In 2007, a RYGBP was carried out in 42.1% of all bariatric procedures. Among all patients, 74.4% were female. The mean BMI ranged from 48.5 kg/m2 in 2005 to 48.0 kg/m2 in 2007. Follow-up data after 12 months were available for 63.8% of the patients operated in 2005 and 2006. The mortality was 0.1% (30 days) and 0.16% (overall).
As indicated by the worldwide trend, there is an ongoing change from GB to sleeve gastrectomy (SG) and malabsorptive procedures. The BMI of German bariatric surgical patients is substantially higher than that of patients from most other countries. There were no differences in overall outcomes during follow-up as compared to published studies.
大多数关于减重手术结果的研究都是作为临床试验进行的，或者反映了单个中心的临床经验。自 2005 年 1 月 1 日以来，在马格德堡奥托·冯·格里克大学外科质量保证研究所的合作下，对德国的减重手术状况进行了检查。
在这项前瞻性多中心观察性研究中，使用互联网在线数据登记系统，前瞻性地收集了 2005 年至 2007 年期间，参与医院对肥胖症连续患者进行的所有原发性减重手术（包括所有重复手术）的原始数据。研究了围手术期特征，如诊断测量的范围、手术类型以及短期和长期结果。
在研究期间，共进行了 3123 例手术。2005 年和 2006 年，胃带（GB）是最常进行的手术，其次是 Roux-en-Y 胃旁路术（RYGBP）。2007 年，RYGBP 占所有减重手术的 42.1%。所有患者中，女性占 74.4%。平均 BMI 从 2005 年的 48.5kg/m2 降至 2007 年的 48.0kg/m2。2005 年和 2006 年接受手术的患者中，有 63.8%可获得 12 个月的随访数据。30 天的死亡率为 0.1%，总死亡率为 0.16%。
与全球趋势一致，GB 向袖状胃切除术（SG）和吸收不良手术的转变正在进行。德国减重手术患者的 BMI 明显高于大多数其他国家的患者。与已发表的研究相比，在随访期间，总体结果没有差异。
