Defecating proctography: local experience.

Between October 1990 to November 1991, defecating proctography was performed on a select group of patients with complaints of persistent constipation or sensation of incomplete evacuation. Out of the 27 patients studied, a high percentage (88.8%) showed some form of anatomical or functional abnormality of the defecating mechanism. As defecating proctography is a relatively new mode of investigation locally, we briefly describe our method and results. These include rectocele formation, intrarectal mucosal prolapse, intussusception and pubo-rectalis paradox. Some of these cases may be amenable to surgical correction.
