Percutaneous transhepatic cholangioscopy for diagnosis and therapy of biliary disorders

Abstract

Objective: The purpose of this study was to determine the incidence of occult rectal prolapse (rectal intussusception) by defecating proctography in patients with clinical rectoceles and defecatory dysfunction. Study Design: Patients who were seen from September 2000 through August 2001 with defecatory dysfunction and clinical rectoceles underwent single contrast defecating proctography. Radiologists who specialized in gastrointestinal fluoroscopy interpreted the results, which were retrieved from a computerized database. Study Design: Sixty patients who met the inclusion criteria were evaluated. Twenty patients (33%) had intussusception; 58 patients (97%) had rectocele; 1 patient (1.7%) had sigmoidocele, and 6 patients (10%) had anismus (paradoxic contraction of the puborectalis). Results: All but 1 case of intussusception was associated with a rectocele radiographically. Anismus was associated with rectoceles radiographically, except in 1 patient for whom it was the sole finding. Conclusion: The data suggest a 33% incidence of occult rectal prolapse in patients with clinical rectoceles and defecatory dysfunction. This is highly clinically significant because one third of patients who are examined for defecatory dysfunction and rectocele may require sigmoid resection rectopexy along with other reconstructive procedures to restore pelvic floor function and prevent symptomatic recurrence.
