The devitalization of the stomach by a devascularization technique.
Different parts of the stomach in healthy animals (pigs) were devitalized (devascularized) by eliminating the blood supply and left in situ. In model experiments, parts of the stomach were chosen for the devitalization with respect to most frequent location of carcinomas. The operation technique consisted of a complete ligature of perigastric vessels, bling enclosure of the cranial part of the duodenum with two ligatures with a possible application of a seromuscular suture and transverse cutting of the oral part of the stomach and its enclosing by a suture with a partial invagination of the wall. The passage was renewed by a gastroenteroanastomosis, some of the used modifications of the operation technique according to Billroth II (Schlater-Pólya). A method was mostly proposed with an interposition of the jejunal loop, which bridged the site of the devitalized part of the stomach. In 10 to 20 weeks the stomach tissue was stepwise degraded and it was replaced by fibrous tissue. The operation technique is simple; it could be applicable as a palliative or possibly therapeutic intervention in the case of inoperable tumours in human practice.
