apical prolapse, sacrospinous Ligament Fixation
Brief summary
SSLF is typically a suture-based attachment of the vaginal apex to the sacrospinous ligament, either unilaterally or bilaterally. It is usually accomplished with specially designed equipment in English-language scientific literature. However, these instruments either reusable or disposable are relatively expensive and difficult in accessibility, and are not yet widely applied around China. Typical Asian smaller pelvis offers us an optional repair procedure with conventional surgical instruments instead of special instrument.
Detailed description
Apical prolapse is defined as descent of the uterus and cervix, the cervix alone, or the post-hysterectomy vaginal cuff down to the hymen, lower vagina, or past the introitus. Among 684,250 POP procedures that were performed in 15 Organization for Economic Co-operation and Development (OECD) countries in 2012, apical compartment repairs represented 20% of these procedures. Sacrospinous ligament suspension (SSLF) as a typical native tissue repair procedure is one of the most widely used vaginal procedures for correcting apical prolapse. SSLF is typically a suture-based attachment of the vaginal apex to the sacrospinous ligament, either unilaterally or bilaterally usually with specially designed equipment such as Deschamps ligature carrier or Miya hook. However, these instruments are expensive and are not yet widely applied in China. Typical Asian smaller pelvis offers us an optional repair procedure with conventional surgical instruments instead of special instrument. Previous pilot study from Peking Union Medical College Hospital showed promising curative results with conventional surgical instruments in Chinese female patients. The investigation may show us a feasible, economic and effective modified procedure for Asian patients with medium compartment prolapse. This is a multi-center, prospective clinical trial. Previous studies using conventional surgical instruments for 1-year follow-up showed objective cure rate was 98%, subjective satisfaction was 94%, Considering that the objective cure rate may decrease in multicenter trials, it is assumed that the objective cure rate of multicenter trials can reach 95%. When the sample size is at least 79 patients, 80% of the test efficiency can verify that the objective cure rate is higher than the target value when the bilateral α=0.05. The missing rate was about 10%. The incidence of SSLF failure requiring other operations method due to deep pelvic cavity and unsatisfactory exposure by conventional instruments was about 5%. The final number of cases included in this study should be 100 cases. Ischial spinous fascia fixation (ISFF) will be the replacement procedure if SSLF will not be accomplished by conventional surgical instruments due to unsatisfactory exposure of spinous fascia. The research units will collect perioperative data and complete unified format case report form (CRF) for all selected patients for further analysis. A total of at most 9 months will be required to complete the study after starting up.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Success rate of SSLF with conventional instruments | up to 36 months after operation | 1. Symptomatic prolapse below grade II occurred at 3 months after operation, and the severest indication point in POP-Q evaluation was taken as the criterion. No vaginal swelling sensation, that is answer no for PFDI-20 Questionnaire Question 3, Do you often see or feel vaginal tumors come out?. 2. The patient's self-perception symptoms is improved or improved significantly, that is answer 1 or 2 for the PGI-C questionnaire. 3. There is no need of further treatment for prolapse, such as reoperation or pessary. 4. Pelvic MRI evaluation on postoperative 3 months follow-up |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| visual analogue scales | within 3 days after operation | postoperative pain evaluation esp. hip pain by visual analogue scales (VAS). Visual Analogue Scale (VAS) is a self-report measure consisting simply of a 10 centimeter line with a statement at each end representing one extreme of the dimension being measured (most often intensity of pain) |
| symptomatic improvement using validated instruments(PFIQ-7) | up to 36 months after operation | Relief of symptoms using validated instruments, pelvic floor impact questionnaire short form 7(PFIQ-7)。PFIQ-7 scores 0-300, the higher the severer negative influence on patient. |
| Postoperative recurrence | from 3 months after operation up to 36 months after operation | Evaluation on the prolapse of the anterior, middle and posterior pelvic confirms POP-Q II degrees and above. |
| symptomatic improvement using validated instruments(PISQ-12) | up to 36 months after operation | Relief of symptoms using validated instruments, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire short form(PISQ-12), PISQ-12 scores 0-48, the higher, the severer negative influence on patient. |
| symptomatic improvement using patient global impression of change (PGI-C) | up to 36 months after operation | Relief of symptoms using patient global impression of change (PGI-C)， PGI-C scores 1-7, the higher, the the severer negative influence on patient. |
| symptomatic improvement using validated instruments(PFDI-20) | up to 36 months after operation | Relief of symptoms using validated instruments, pelvic floor distress inventory short form 20(PFDI-20), PFDI-20 scores 0-300, the higher the severer negative influence on patient. |
