| Popis: | OBJECTIVE The aim of the study was to compare the efficacy and safety of the tissue anchoring system (TAS) kit versus the traditional technique for sacrospinous ligament fixation (SSLF) to treat apical vaginal wall prolapse. METHODS A prospective randomized controlled multicenter study of noninferiority involving women with apical prolapse (C-point≥+1). Primary outcome is surgical success as C-point≤-4 at the 1-year follow-up. Secondary outcomes are success according to the composite criteria as C-point≤-4, Ba-point ≤0, and Bp-point ≤0; POP-Q measures of the vaginal compartments; intraoperative findings, complications; reoperation rate; hospital stay; and quality of life and sexual functioning (PISQ-12). It was estimated that 50 individuals per group would yield an 80% power for a noninferiority margin of 15%. RESULTS Ninety-nine women were randomized: TAS (n = 55) and traditional SSLF (n = 44). The groups' preoperative data were similar. Drop-out rate was 11% for 12-month follow-up. Success rates were 90% for TAS and 80% for traditional SSLF (P = 0.0006; absolute difference, 9.8%; 90% confidence interval, -5.2 to 24.8) with the sensivity analyses per-protocol considering only the subjects that completed the 12-month follow-up and 80% versus 73%, respectively (P = 0.0048; absolute difference, 7.3%; 90% confidence interval, -9.6 to 24.2) by sensivity analyses considering the total number of participants randomized and treated with drop-out cases as failure. We detected shorter intraoperative time to dissect and reach the SSL, shorter length of hospitalization, lower rates of urinary tract infection, and lower pain scores in the first 30 days postoperative in the TAS compared with the traditional SSLF groups (P < 0.05). There was an improvement in women's quality of life that did not differ between groups. CONCLUSIONS The modified technique of SSLF using the TAS kit is noninferior to the traditional technique for the treatment of apical compartment in 12-month follow-up. |
