[Radiologic results of an artificial pylorus performed primarily in patients with Billroth II gastric resection].
The authors describe the radiological results after primary execution of an "artificial pylorus". In 18 patients were done a troncular vagotomy, hemigastrectomy (Billroth II) and Braum jejunal anastomosis. In twelve of this patients an "artificial pylorus" were done on the efferent loop, 10 cm distant of the gastroenterostomy and before the jejunal Braun anastomosis. The technique, previously described, was a 3 cm circumferencial ressection of the longitudinal muscular layer and circular layer plicature. The cut edges were approached. A significant delay in gastrojejunal emptying was observed in patients with an "artificial pylorus" caused by the effective presence of a sphincter-like mechanism.
