[Hemorrhagic recurrence after operations of azygoportal disconnection].Rev Esp Enferm Apar Dig. 1989 Mar; 75(3):246-51.RE
One of the main drawbacks attributed to azygoportal disconnection operations in the surgical treatment of bleeding esophageal varices is recurrence of hemorrhage. The present paper reviews the results obtained as regards hemorrhage recurrence in 4,975 patients who underwent azygoportal disconnection in 41 series published in the western literature in recent years. An analysis is also made of the factors that, according to different authors, could be related to the failure of these procedures to prevent eventual variceal hemorrhage.
