  • Associated factors include postoperative fever, hematoma formation / failure to maintain adequate hemostasis, poor physical condition, insufficient preoperative vaginal preparation, difficultly with surgical procedure, use of intraperitoneal vaginal drains and packs
Clinical features
  • Occurs two months to eight years after surgery
  • May present with watery vaginal discharge, lower abdominal pain, dyspareunia
