Bilhariziasis and prolapse of the rectum

Twenty-six cases with complete prolapse of the rectum were investigated. In 8 of these, bilharziasis of the rectum and colon was found to be the cause of the prolapse. The role of bilharziasis in the pathogenesis of this condition is discussed. The age and sex incidence of bilharzial prolapse differs from that of cases without bilharziasis.
