AbstractDefecography 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 constipa
tion, 2 patients with incomplete defecation and mucous bloody stool in one case. The defeco
graphic 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, intus
susception, infolding and ulceration. 3) pelvic floor descent. The results showed abnormal ano
rectal 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.
ronsequently, 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.
