title: [Radiological evaluation of a new method for gastric replacement by the interposition of an isoanisoperistaltic jejunal segment (author's transl)].
abstract: The method of reconstruction following total gastrectomy decisively influences early and late post-operative results. The ideal form of reconstruction would create a reservoir resembling a stomach, it would prolong intestinal transit time, preserve orthograde passage through the duodenum, prevent reflux of bile into the oesophagus, and should not be very difficult technically. A new method of gastric replacement and its radiological investigation is described. The passage from the oesophagus to the duodenum is reconstructed by the interposition of an iso- and anisoperistaltic jejunal segment. The iso- and anisoperistaltic segments result in contrary movements which can be divided into various basic types. Type I is by far the most common form, comprising 70% of the patients examined; it shows characteristic to-and-fro motion of the food-contrast mixture, resulting in a reservoir function of the isoperistaltic segment and intermittent emptying into the duodenum. In type II, incomplete local ring contractions can be observed in the isoperistaltic segment, with reservoir function and intermittent emptying. In type III emptying results from overflow. The operative technique and clinical results are described.
