A Case of Vesicovaginal Fistula Repair with Rectus Abdominus Myofascial Interposition Flap after Radical Hysterectomy and Radiation Therapy

摘要

Vesicovaginal fistulas (VVFs) caused after radiation are difficult to repair and require interposition of non-irradiated, well-vascularized tissue between urinary bladder and vagina. A 48-year-old female suffered cervical cancer and underwent radical hysterectomy followed by radiation therapy which caused VVF. The initial surgical repair performed 3 months after development of VVF, was unsuccessful because of the absence of peritoneum or omentum to interpose between urinary bladder and vagina probably due to history of cesarean section and radical hysterectomy. The second surgical repair was performed 15 months after the first surgery utilizing a rectus abdominus myofascial (RAM) interposition flap. Fifteen months after the second operation, she remains free from incontinence. This case suggests that RAM is useful even for postradiation VVF.
