Abstract

Longitudinal vaginal septum, a rare congenital fusion defect of mullanan ducts rarely causes dystosia of labour and total uterine prolapse. Several surgical techniques were developed for repair of prolapse but no consensus has been reached on one type of operation1.

Case Report

A 25 years old female was admitted with a few months history of uterine prolapse. She was married 4 years ago and had her first coitus 5-6 months laterbecause of pain. She could not get pregnant earlier than 3 years alter her marriage although she wanted to . Labour pains began at term but the delivery process did not begin although pain lasted long. In the hospital where she was admitted before the vaginal septum was excised and a 3900 g live baby was delivered. Her postpartum and puerperal period was uneventful and sexual intercourse painless after birth of her baby. One year later she developed uterine prolapse. On gvnaecological examination, she had total uterine prolapse with remnants of septum on the anterior and posterior part of vagina 1 cm in width and 4 cm in length (Figure).

The patient had no symptoms of stress urinary inconti­nence. Being diagnosed as total uterine prolapsus, she was hospitalized. No pathological findings were noticed in routine examination. Superior and inferior abdominal ultrasonogra­phy and IVP were done to exclude a general connective tissue weakness and any other abnormality. No abnormalities were noted. Nichol’s operation tcchnique2 was chosen to protect reproductive functions of the young patients. Through an infraumbilical median incision the abdomen was opened. The pentoneum was opened 2 cm at the upper third of sacrum. A longitudinal tunnel containing 1/3 of sacrum was established by using a long and curved kidney stone forceps. An 4x8 cm wide prolene mesh was folded longitudinally four times (like a ligament) and was attached to the cervix bilaterally between uterosacral ligaments by using two 0 prolene sutures. The other edge was passed through the tunnel and alter elevating the uterus, it was fixed with two sutures to the periosteum of the sacrum bilaterally. Peritoneum reapproximated covering the prolene strap throughout its length. Afterward the Retzius space was entered. Burch operation was done by bilaterally placing three 0 vicryl sutures at a side that was passed through the perivaginal facia and Cooper ligament. The abdomen was closed anatomically. Gynaecological examination done on the 2nd. 6th and 12th postoperative months was satisfactory.

Discussion

Longitudinal vaginal septum is the fusion defect of Mullerian ducts. It may be partial or complete and it can be at inferior, middle or superior part of the vagina. Sometimes it covers every part of the vagina and two cervices and two uteruses may accompany it. It may lead to infertility and recurrent abortions. Inferiorly placed septum should be operated because it makes coitus difficult3. In our case also, the septum was in the inferior part of vagina; difficulty in coitus andinfertility were mentioned in her history. Edward and Gale4 described as an inherited autosomal dominant abnonnality associated with urinary incontinence due to bladder neck abnormalities together with hand abnor­malities. Johanson- Blizzard Syndrome, is inherited autoso­mal recessively with a longitudinal vaginal septum5. Several factors arc responsible for uterine prolapse. The most common cause being destruction of pelvic supportive tissues, ligaments, facias, muscles and nerves which can occur during vaginal delivery. Multiparity is also an important factor. Damage is seen mostly during operative deliveries with head and shoulder distosia and prolonged labour1. In our case, these reasons did not exist, whereas there was a vaginal septum which rarely causes dystocia. At present, developments in obstetrics, common prac­tice of caesarean section, use of contraception widely led to a decrease inmultiparity which also caused a decrease in uterine prolapses. The type of prolapse seen in multiparous women can also be seen in nulliparous together with congenital clongatio collie2. In some cases of total uterine prolapse, stress urinary incontinence does not occur owing to folding of urethrovesical function and urethra during stress3. This symptom was not seen in our case. We added Burch colpo suspension to the operation aiming for stress urinary incontinence prophylaxis, presuming that attaching the vagina to Cooper ligament will provide an additional support. In young patients with total prolapse whose uterus should remain, the types of operations to be preferred are as follows; Modified Gilliam Doleres Suspension operation1 with uterosacral ligament plication and culdeplasty may be com­bined with suprapubic colpourethropcxy and/or appropriate colporaphies. In Richardson and Ulfelder technique3, utemsacral ligament is attached to sacrospinal ligament transvaginally. Manchester operation1 with cervical amputa­tion, anterior plication of cardinal ligament, with appropriate colporaphies can provide proper support in patients with elongatio collie. This operation is usually done in Europe. In Williams’6 transvaginal technique, cardinal and uterosacral ligaments are first shortened and then attached to anterior part of cervix. This operation is not usually preferred. In all these operations which are aimed at preservation of fertility, there is a probability of recurrence. By the time the patient decides to have no more pregnancies, additional operations may become necessary. In our case, instead of fascia lata strap defined by Nichols3, prolene strap was used. The disadvantage of these operations is progression of cystocele and rectocele. Colporraphy is required, if there is a recurrence of vaginal prolapse but vaginal approach cannot be used. If hysterectomy is necessary, it may have to be performed transabdominally. Prolapse can be seen after menopause also. Besides the weakness in supportive tissue due to lack of estrogen, causes leading to an increase in intraabdominal pressure such as chronic obstructive respiratory disease, obesity, pelvic tu­mour, ascites, excessive exercise, heavy lifting, using firm corsets and straining at defecationwhich is due to anal stenosis or retrovert uterus also may contribute to the formation of prolapse. Parks et al. 7 suggested straining while defecation may be due to neuropathy affecting the pelvic floor muscles. Factor such as chronic constipation, chronic cough, obesity; excessive exercise and any congenital connective tissue weakness were not observed in this case. There was soft tissue distosia (longitudinal vaginal septum) in her history which is rare instead of more common causes such as shoulder dystosia and cephalopelvic disproportion that cause total uterine prolapse in young patients.In antenatal follow-up of pregnancy, a vaginal examination will decrease morbidity. If vaginal septum is established, it should be operated in the second trimester.
