Spontaneous vaginoperitoneal fistula as a rare complication of carcinoma ovary: a case report.

Background: Spontaneous vaginoperitoneal fistula formation in a case of carcinoma ovary is a very rare occurrence and has never been reported.

Case Presentation: A 55-year-old postmenopausal lady presented with complaints of abdominal distention and mass coming out of the vagina for the last 10 days. On examination, she had tense ascites, uterovaginal prolapse and hard, fixed mass felt anteriorly on per-rectal examination. Biochemical investigations and radiological imaging suggested advanced stage ovarian neoplasm. She was planned for neoadjuvant chemotherapy. During the second cycle of chemotherapy, she developed spontaneous vaginoperitoneal fistula which was confirmed on exploratory laparotomy where interval debulking surgery was performed in collaboration with gastro-surgeons on a semi-emergency basis. The postoperative course was uneventful.

Conclusion: Spontaneous vaginoperitoneal fistula is a rare complication and should be kept in mind while managing advanced ovarian neoplasm.
