Original publication title: Long-Term Complication: Colovaginal Fistula Nine Years after Laparoscopic Sacrocolpopexy.
Plain-English summary
A woman in her seventies developed a rare condition called a colovaginal fistula, which is an abnormal connection between the colon and the vagina, nine years after having surgery to support her pelvic organs. She noticed a yellow, foul-smelling discharge from her vagina, and tests showed that she had a rectovaginal fistula, but there was no sign of diverticular disease, which is a different issue. A team of specialists performed surgery to remove the damaged mesh from her previous operation and fixed the affected part of her colon. After one year, she was completely healed and no longer had any unusual discharge. This case shows that complications can occur many years after surgery, and careful monitoring and prompt treatment are important for recovery.
Abstract
<h4>Background</h4>Colovaginal fistula (CVF) is a rare, late complication of laparoscopic sacrocolpopexy that significantly impairs quality of life. We report a case occurring 9 years postoperatively to highlight its presentation and management.<h4>Case</h4>A G3P3 woman in her seventies presented with yellow, foul-smelling vaginal discharge 9 years after laparoscopic total hysterectomy with sacrocolpopexy. Colonoscopy revealed a rectovaginal fistula; histology excluded diverticular disease. A multidisciplinary team performed laparoscopic removal of the eroded mesh and sigmoid resection with primary anastomosis. At 1-year follow-up the vagina was completely healed and the patient reported no further abnormal discharge.<h4>Conclusion</h4>CVF may arise almost a decade after sacrocolpopexy. A high index of suspicion, prompt multidisciplinary surgery and long-term surveillance are essential for optimal outcomes.
