[New developments in abdominal surgery].

New developments in abdominal surgery are mainly dependent on advances in other medical and technical fields. Thus, for example, the treatment of gastroduodenal ulcer, which was a main and classical field of surgery in the past, more and more turns to become conservative. The modern techniques of non-invasive diagnostic procedures (ultrasonography, CT-scan) influence surgery, in particular they help to specify its indication. In the future tumor surgery will continue to be a main field in surgery and organ transplantation will gain significant importance.
