Abstract
Rectocele as well as paradoxical sphincter reaction may lead to rectal emptying difficulties and outlet obstruction. Forty-one patients with emptying disturbances and rectocele were investigated with defecography, anorectal manometry, colon transit time, and electromyography. Twenty-nine patients (71 percent) had concomitant paradoxical sphincter reaction, and 13 of these also had increased colon transit time. The functional results after surgical treatment of rectocele are not always satisfactory, probably because patients often have several causes for their emptying disturbances. It is emphasized that careful preoperative investigations are important before surgical treatment of rectocele in patients with emptying difficulties.
