DOUBLE PYLORIC CHANNEL. ETIOPATHOGENIC AND DIAGNOSTIC CONSIDERATIONS. THE PRESENTATION OF 5 CASES

Abstract

The authors present 5 cases of double pyloric channel diagnosed in the Digestive Endoscopy Unit of the Real Hospital Portugues de Pernambuco, Brazil, out of 8, 000 examinations carried out from September 1973 to July 1980. Two etiopathogenic possibilities are discussed and the authors conclude that, in the light of the clinical and endoscopic findings, all their cases seem to be of acquired origin. In conclusion, they suggest that the terms “double pylorus”and “antrobulbar fistula” are the most appropriate designations for, respectively, the congenital cases and the acquired ones.
