Persistent ischiorectal fistula secondary to rectal extrusion of posterior vaginal mesh: Case report.

Introduction And Hypothesis: Vaginal mesh has been used for years to try to improve the results of pelvic organ prolapse surgery, but current evidence does not confirm this improvement and instead describes serious and frequent adverse events.

Clinical Case: 64-year-old patient with rectal extrusion of posterior vaginal mesh placed 8 years earlier, and persistent left ischiorectal fistula refractory to surgery. She required 5 surgeries, carried out jointly between gynecology and general surgery, to solve, firstly, the bilateral perianal abscess secondary to extrusion of the posterior vaginal mesh into the rectum and then the persistent left ischiorectal fistula, despite the removal of the material prosthetic. Finally, the fistula was solved by injection of platelet-rich plasma.

Conclusions: Vaginal mesh complications often need a multidisciplinary approach, and treatment may require multiple approaches and more than one surgical procedure. In the case of a persistent fistula refractory to surgery, after removing the mesh, non-invasive regenerative therapies that promote vascular growth and tissue regeneration could be considered such as platelet-rich plasma.
