A three-year prospective assessment of rectocele repair using porcine xenograft.
OBJECTIVE
To prospectively evaluate clinical outcome of rectocele repair using xenograft 3 years after surgery.


METHODS
Twenty-three patients who completed evaluation preoperatively and 1 year after surgery were assessed at a 3-year follow-up. Clinical examination was performed preoperatively, and at the 1- and 3-year follow-ups, with the pelvic organ prolapse quantification system. Symptom assessment was performed with a validated bowel function questionnaire including questions on sexual function.


RESULTS
There were no graft-related complications during the 3 years following surgery. Preoperatively, all patients had stage II prolapse of the posterior vaginal wall and a rectocele verified at defecography. At the 1-year follow-up, 11 of 29 patients (38%) had rectocele of stage II or more, and 4 patients were reoperated. At 3-year follow-up 7 of 23 patients (30%) had rectocele of stage II or more. When including the 4 early anatomical recurrences, a total of 11 of 27 patients (41%) had rectocele of stage II or more at 3-year follow-up. Preoperatively, all patients reported varying degrees of rectal emptying difficulties and symptoms of bowel dysfunction. There was a significant decrease in rectal emptying difficulties (P < .01), sense of incomplete evacuation (P < .01), need for manually assisted defecation (P < .05), and symptoms of pelvic heaviness (P < .001) at the 3-year follow-up compared with preoperatively. Cure of rectal emptying difficulties was reported by fewer than 50% of patients. There were no significant changes in anal incontinence scores or symptoms of sexual dysfunction at the 3-year follow-up compared with preoperatively.


CONCLUSIONS
Rectocele repair using porcine dermal graft was associated with an unsatisfactory anatomical cure rate and persistent bowel-emptying difficulties in the majority of patients 3 years postoperatively.
