Case report: diagnosis and management of peritoneovaginal fistula.

Fallopian tube vaginal fistula, a form of peritoneovaginal fistula, is an uncommon cause of persistent vaginal leakage after hysterectomy. Fallopian tube vaginal fistula resulting in peritoneal leakage has been reported in conjunction with a prolapsed fimbria. Herein is presented a case of fallopian tube vaginal fistula without a visibly prolapsed tubal fimbria. The patient was a 43-year-old woman with a 6-year history of cyclic vaginal leakage with onset shortly after vaginal hysterectomy. Examination using a vaginal speculum revealed a clear vaginal fluid but no distinct lesion or mass in the vagina, and bimanual examination did not reveal a vesicovaginal or ureterovaginal fistula. Laparoscopic surgical exploration revealed a densely adherent fallopian tube attached to the vaginal cuff, forming a fallopian tube vaginal fistula.
