Does surgery resolve outlet obstruction from rectocele?

In order to ascertain whether plastic surgery for rectocele is of value in the treatment of outlet obstruction, a retrospective study was made of 21 women complaining of difficulty in expelling faeces: 13 patients (group A) underwent surgery with transanal longitudinal plication of the anterior rectal wall (Block's technique), and 8 patients (group B) had colpoperineoplasty which, in 2, was associated with bladder-neck suspension following the Raz-Peyrera technique for urinary incontinence. The mean follow-up was 24.2 +/- 18.7 and 36.8 +/- 17.8 months respectively. In 11 group A patients (80.9%) and 6 group B patients (75%) cure, or an improvement, was achieved. Of the remaining 4 patients (19%), recurrent rectocele was found in 2 (one group A and one group B) and intestinal transit time tests detected colonic constipation in one group A and in one group B patient. It is concluded that surgery can resolve outlet obstruction from rectocele, but Block's technique is preferable because it is more straight-forward and easier.
