Is development in bariatric surgery in Germany compatible with international standards? A review of 16 years of data

Updates Surg. 2022 Oct;74(5):1571-1579. doi: 10.1007/s13304-022-01349-8. Epub 2022 Aug 8.


Bariatric surgery has expanded tremendously internationally over the past decade. In recent years, bariatric surgery has experienced a significant growth in Germany. However, the question arises as to whether this development is in line with international developments or whether there is still room for improvement that could be challenged. 63,990 primary bariatric procedures recorded in the German Bariatric Surgery Registry (GBSR) were analyzed from 2005 to April 2021. The distribution of procedures according to different variants was analyzed and presented. In the last 16 years, 17 different procedures have been performed. The most common surgical procedure was sleeve gastrectomy (SG), followed by Roux-Y gastric bypass (RYGB) (42%). Adjustable gastric banding (AGB) has declined over time, from 23.5% in the first 5 years to 0.2% in recent years. In comparison, omega-loop gastric bypass has increased over the past 5 years (from 0.4% in the first 5 years to 5.9% in the last 5 years). Laparoscopic procedures have accounted for 96.4% of all bariatric surgeries in recent years. The frequency of some procedures has decreased and some bariatric procedures have lost significance. Overall, bariatric surgery in Germany has developed positively compared to the international trend. Nevertheless, there is one area that needs to be optimized: the development of robotic bariatric surgery, which crawls behind in Germany compared to other countries. To establish the technology in bariatric surgery in a timely manner, a balance must be found between cost neutrality and patient-oriented applications.
