Vaginal repair of a sigmoidocele.

Sigmoidocele is an uncommon accompaniment of pelvic prolapse. It is difficult to detect a sigmoidocele during clinical pelvic examination, and as a consequence a sigmoidocele may be unexpectedly encountered during vaginal repair of pelvic prolapse. The author has discovered and repaired a sigmoidocele during vaginal surgery in 4 patients with either complete procidentia or vaginal vault eversion. The procedure involves a modification of the bilateral sacrospinous vaginal vault fixation using two additional sutures to suspend the sigmoid colon from the sacrospinous ligament. Clinical and functional results have been excellent. This is the first description of a vaginal approach to the repair of a sigmoidocele.
