Comparison of Posterior and Anterior Approach to Sacrospinous Ligament Apical Fixation - Randomized Controlled Trial

Pelvic Organ Prolapse, Surgical Procedure, Unspecified

Pelvic organ prolapse (POP) is a common problem among women. Apical prolapse (AP) is a prolapse of the uterus, or vaginal cuff, in women post hysterectomy. Apical fixation to the sacrospinous ligament (SSLF) was first introduced in 1968 by K.RICHTER. .In a large review study, the subjective cure rate after SSLF ranged from 70 to 98%, while objective cure rate was 67-97%. The success rates of SSLF in a randomized study comparing SSLF to uterosacral ligament fixation after two years were 63.1%. In women with combined apical and anterior wall prolapse, SSLF can be performed in two ways: anterior access through the anterior vaginal wall or posterior approach through the posterior vaginal wall. A retrospective comparison of the two methods was performed, demonstrating some efficacy to the anterior approach over the posterior approach mainly in respect to the vaginal length. From the literature review to date, no comparisons were made between the methods in a randomized controlled trial. Objective: To compare the success rates between two approaches (anterior and posterior) for SSLF

Pelvic organ prolapse (POP) is a common problem among women and its incidence is rising due to population aging. Approximately 11-19% of women will undergo surgery for pelvic organ prolapse (POP) or urinary incontinence during their lifetime and approximately 30% will need repeat surgery during their lifetime .Apical prolapse (AP) is a prolapse of the uterus, or vaginal cuff, in women post hysterectomy. The severity of the prolapsed organ can be graded according to the POP-Q classification .There are several approaches to apical fixation, some of which are done vaginally and include fixation by sutures to the uterosacral ligament (USLF) or the sacrospinous ligament (SSLF). A mesh can be used for ligament fixation as well. The abdominal approach is also an option, the sacro-colpo-pexy fixation using a Y mesh. Apical fixation to the SSL was first introduced in 1968 by K.RICHTER. medical devices such as the Capio that assist in performing SSLF were also developed with ease. In a review article that included 2,390 women undergoing SSLF subjective cure rate ranged from 70 to 98%, while objective cure rate was 67-97% .Such fixation in combination with posterior or anterior wall repair, especially after hysterectomy, showed a 94% objective cure rate at 7-year postoperative follow-up. A randomized study (The OPTIMAL randomised trial) comparing SSLF with USLF found no preference for either method. Success rates were measured according to three criteria - 1) no significant vaginal dome or one of the vaginal walls 2) no vaginal bulge symptoms 3) no need for repeated surgery within two years of the original surgery. According to this study, the success rates of SSLF after two years were 63.1%. Among women with anterior vaginal wall prolapse and AP, SSLF can be performed in two ways: anterior access, ie dissection through the anterior wall of the vagina or fixation through the posterior wall of the vagina. A retrospective comparison of the two methods was performed, demonstrating some efficacy in anterior approach in terms of vaginal length and postoperative apical fixation with less reference to healing rates or impact on the anterior compartment, compared with a posterior approach. From the literature review to date, no comparisons were made between the methods in a randomized controlled trial. Objective: To compare the success rates of two approaches (anterior and posterior) for SSLF
