Abstract

Bladder dysfunction thought to be due to partial denervation has been described following radical hysterectomy. Some patients experience acute and chronic rectal dysfunction characterized by difficulty with defecation and loss of defecatory urge. To define this abnormality, anorectal pressure profiles were examined in 15 patients with Stage I carcinoma of the cervix before and after radical hysterectomy. Profiles were done using standard anorectal manometry with a water-infused system. In all patients preoperative manometric profiles were normal; postoperative studies were abnormal in all patients. Features seen include altered relaxation of the internal sphincter, increased distension needed to trigger relaxation, and decreased rectal sensation; external sphincters and resting internal sphincters were unchanged. Postoperatively, 12 patients reported problems with rectal function. A physiologic defect is definable in patients undergoing radical hysterectomy; this suggests disruption of the spinal reflex arcs controlling rectal emptying. These physiologic abnormalities correlate with the clinical symptomatology experienced by some patients. Continuing definition and evaluation of management options in this situation should be useful in developing effective therapy for rectal dysfunction following radical hysterectomy.

    It has been demonstrated that direct injury to the parasympathetic nerves lateral to the vaginal fornix and in the broad ligament of the uterus are responsible for post-hysterectomy constipation [29]. Since RH involves extensive dissection of the pelvic structures, it is probably to cause more damage to the innervations of rectum than would simple hysterectomy [30]. Recently Park et al. [31] confirmed that deficit of rectal sensory function is the characteristic pathophysiology in patients experiencing constipation after RH [31].
