[Interposition of the jejunal loop in the surgical treatment of gastroduodenal ulcer, postprandial syndromes and gastric cancer].

50 cases of interposition of jejunal loop (32 for gastric cancer and 18 for ulcerous pathology) carried out over the last 3 years are reported. From a technical point of view and as an alternative to degastroenteroanastomosis, interposition of the loop is preferred in partial oral end-to-end on the stomach. In neoplastic lesions, Mouchet-Camey type reconstruction was adopted as a routine measure. After describing the complications of the operation and analyzing the causes, the long-term results are evaluated using absorption curves with 131-I labelled oleic acid. The excellent weight increase in the inflammatory forms, and the lack of reflow and dumping in patients subjected to total gastrectomy for cancer, confirm the value of the technique.
