title: [Role of radiologic diagnosis in rectal mucosal prolapse].
abstract: Defecography (DG) is a useful method to detect many morpho-functional deformities of anus and rectum and pelvic floor. We report on a clinical and radiologic study of 165 patients (36 men and 129 women) suffering from defecation disorders and rectal muscosal prolapse (RMP). All the patients had been submitted to clinical examination, endoscopy and double contrast enema to rule out organic colorectal conditions. DG was performed with a dedicated conmode and high-density barium and videorecorded on VHS cassettes to assess the dynamics of evacuation phases and to reduce exposure doses. DG showed single RMP in 28% of cases and multiple RMP in 72% of cases; the condition was isolated in 22% of cases, while in 88% of cases it was associated with other anorectal dysfunctions, such as rectocele (65%), perineal descent syndrome (PDS) (15%), puborectal muscle syndrome (14%) and intussusception (8%). RMP appeared at DG as a wall defect bulging into rectal lumen, which was more evident under straining and during barium evacuation. In 12 patients with multiple RMP, dynamic CT of the pelvis was carried out to study the whole pelvic floor and in 5 cases it showed levator ani diastasis. Fifty-eight patients were submitted to surgery by elastic binding of RMP; DG follow-up showed RMP remission in 47 patients, single RMP relapse in 3 patients and multiple RMP relapse in 3 patients. One patient with PDS and intussusception was submitted to rectopexy and mucosectom.
