Defecography in patients with anorectal disorders: a study in 27 cases.

Defecography of twenty-seven cases of anorectal disorders with an age range from 22 to 86 years, were evaluated from June 1989 to February 1999. There were 24 patients with constipation, 2 patients with incomplete defecation and mucous bloody stool in one case. The defecographic results were analyzed regarding the following 1) anorectal angle, defined both at rest and straining 2) abnormalities of the rectal configuration during straining, including rectocele, intussusception, infolding and ulceration. 3) pelvic floor descent. The results showed abnormal anorectal angle 5 cases, rectocele 15 cases, intussusception of the rectal wall 3 cases, infolding 11 cases, ulceration 7 cases and anal canal constriction 1 case. Consequently, the patients with anorectal disorders were found to have a variety of rectal abnormalities in which the defecography would be the imaging tool in demonstrating them.
