Sacrospinous ligament fixation (SSLF) is one of the most used native tissue approaches for apical suspension with a high rate of perioperative complications. This study aimed to review cases undergoing a modified SSLF and assess its perioperative adverse events. It was a retrospective study of 168 consecutive patients undergoing modified transvaginal SSLF at a single tertiary center from 2017 to 2021. The sutures were placed on the sacrospinous ligament (SSL) approaching the sacrum through natural spaces under direct vision. Moreover, it was performed bilaterally. Patient demographics and perioperative complications were reviewed. The median age was 65 years, and 85.7% (144/168) had stage III–IV prolapse. Among the 168 patients undergoing this modified SSLF, 161 were for uterovaginal prolapse, and seven were for posthysterectomy vaginal vault prolapse. 83.9% (135/161) patients were concomitant with hysterectomy, and 70.2% (118/168) were with anteroposterior colporrhaphy. The median operation time was 82 min (interquartile range [IQR], 61–100 min), and the median intraoperative blood loss was 50 ml (IQR, 30–50 ml). Two cases had pelvic hematoma, and both were cured after expectant treatment. No patient required a homologous blood transfusion, and none complained about buttock or lower limb pain 2 weeks postoperatively. Nor did injury of the ureters, bladder, or rectum occur intraoperatively. This modified transvaginal SSLF procedure was safe and had no severe perioperative complications.
