Results of transperineal levator-plasty in treatment of symptomatic rectocele

Abstract

A rectocele is a herniation of the anterior rectal wall through the rectovaginal septum into the vagina. The most important risk factors are a previous hysterectomy, obstetic injuries and the descending perineum syndrome. In some patients the rectocele becomes symptomatical because of defecation disorders. The patients have to give manual vaginal or perineal help during defecation. Radiological parameters like the size of the rectocele or retention of barium only have limited value for the clinical evaluation. In a high percentage we find simultaneous symptoms of fecal incontinence. Transperineal anterior levatorplasty makes it possible to close the rectocele. This procedure has a positive influence on defecation and continence. In a prospective study we performed anterior levatorplasty in 35 female patients having a rectocele in combination with rectal outlet obstruction. Subjective improvement of the defecation disorder was found in 74%. Only 1 patient complained of deterioration. No patient needed manual vaginal help postoperatively. Patients who needed perineal help preoperatively had worse results. Patients who did not need any manual help preoperatively nevertheless reported an improvement postoperatively. Fifteen of 20 patients, who suffered from fecal incontinence preoperatively, reported a better continence postoperatively (75%). Even in patients with incontinence the anterior levatorplasty is a good method for rectocele repair, as it improves rectal emptying and simultaneously provides therapy for fecal incontinence.
