Safety and efficacy of sacrospinous vault suspension.

The objective of the study was to determine the success rate and complications of sacrospinous vault suspension when performed by an experienced surgeon. Retrospective data collection was performed for 293 women who had undergone sacrospinous vault suspension at Mount Sinai Hospital, Toronto, between November 1993 and 19 December 1998. Primary outcome measures were complication rates (acute and long term) and success rate, with failure defined as any degree of vault prolapse requiring repeat operation, any degree of symptomatic isolated vault prolapse, or any vault prolapse at or beyond the introitus. Statistical analysis was performed using simple descriptive techniques. During the study period, 305 sacrospinous vault suspensions were performed; however, 12 cases were excluded because of inaccessible records. This study therefore comprised the remaining 293 cases: 129 at the time of vaginal hysterectomy, 5 with transvaginal cervical stump excision, 155 for post-hysterectomy vault prolapse, and 4 without hysterectomy. Two hundred had follow-up of 1 year or more, with maximum follow-up 5 years. Of these 200, there were 6 failures (3%). There were no acute hemorrhages and no deaths. There was a complaint of postoperative right buttock pain in 18 of the 293 procedures (6.1%), with this persisting on a chronic basis in 3 patients. Eight patients complained of new-onset postoperative dyspareunia. Nine patients had postoperative stress urinary incontinence, and 14 patients had de novo anal incontinence. Postoperatively, there were 17 patients with a cystocele and 7 with a rectocele. There were three other complications: one pelvic hematoma at the sacrospinous suspension site, one right foot drop which spontaneously resolved, and one case of pain in the right sciatic nerve distribution which spontaneously resolved. Forty-three patients complained of anal incontinence preoperatively, and 38 (88.4%) had the symptoms resolved postoperatively. It was concluded that, when performed by a surgeon experienced in the procedure, sacrospinous vault suspension is safe and effective, with a successful result at 1 year in more than 90% of cases, and rare major complications.
