[Itinerary through 125 years of German Surgical Congresses].

The German Society of Surgery was founded in 1872 with 127 members. Now there are more than 5000. The first congress was attended by 81 members. In those days, a lively discussion was possible. Meanwhile, many subspecialties have developed from general surgery, which articulate themselves in parallel sessions. For these reasons, a discussion in the plenary does not exist anymore. The conventions predominantly communicate results. No original innovations were recognized immediately. This is evident from examples. Today the industrial exhibition is an important factor for the progress which is linked to these congresses.
