About

319 Women undergoing hysterectomy for benign (not cancer) indications were randomly allocated to 2 types of surgery (Total (TAH) and Subtotal (SAH)) abdominal hysterectomy 15 years ago. They were followed by questionnaire at time of surgery and up to 5 years (not yet published) after the surgery and evaluated regarding following outcomes: Urinary incontinence, pain, bowel problems, per and postoperative complications, sexuality, quality of life, pelvic organ prolapse and vaginal bleeding. Now the investigators are conducting a 15 year follow up with the same out-come measures but also including physical examinations regarding Urinary incontinence, voiding difficulties, pelvic organ prolapse and problems with the cervix. The investigators' hypothesis is that several of the out-come measures will be present in more cases than earlier due to age and menopausal changes. The investigators expect more urinary incontinence in the subtotal group as this was seen at earlier follow ups. The investigators expect to find more women with pelvic organ prolapse with the physical examination than by questionnaire alone, possibly with a higher incidence in the subtotal group.

Full description

The study included women who were offered a hysterectomy for benign uterine disease such as: metrorrhagia, menorrhagia, fibroids, endometriosis,and pelvic pain. Women in need of hysterectomy for malignant disease or because of prolapse of the uterus were not included. They were followed up by a questionnaire covering all outcome measures as described above. Background information was registered in a second questionnaire prior to surgery. All gynaecological departments in Denmark were invited to join the trial. 11 departments contributed randomized patients to the trial.

the results up to 1 year after surgery have been published, links can be found in the citation list. The results from the 5 year follow up have not yet been published.

The questionnaire used in this trial consists of the validated SF-36 (Short Form 36) quality of life questionnaire as well as a thorough questionnaire regarding the outcome measures described elsewhere. The entire questionnaire was validated prior to the beginning of the trial.

A second questionnaire has been added in the 15 year follow up: PFDI-20(Pelvic Floor Distress Inventory 20). The investigators included this, as it is more thorough regarding pelvic organ prolapse and in particular a "bother" measure than the original questionnaire.

The 20 min. pad-weighing test has been tested against the 1 hour gold-standard used by the ICS (International Continence Society) and has been found to give comparable results.

---

319 participants in 2 patient groups

Total hysterectomy

Active Comparator group

Description:

removal of the entire uterus including the cervix. open abdominal surgery. No specific procedures were asked of the surgeon. They were free to do the procedure the way they were used to doing it.

Treatment:

Procedure: Total Hysterectomy

Subtotal Hysterectomy

Experimental group

Description:

removal of the uterine body only leaving the cervix in situ. The surgeon was free to do the procedure as he was used to. The only direction was that the cervical canal should be electrocoagulated.

Treatment:

Procedure: Subtotal hysterectomy
