Recurrent chorioamnionitis and second-trimester abortion because of an enterouterine fistula

BACKGROUND: Chorioamnionitis, a common cause of second-trimester abortion, is usually secondary to an ascending infection. Recurrent chorioamnionitis with second-trimester abortion secondary to an occult enterouterine fistula has not been reported previously. CASE: A 26-year-old Indian woman, para 0-0-2-0, presented with two spontaneous second-trimester losses. Her third pregnancy carried to 24 weeks, but she delivered after the development of pneumonia, bacteremia, preterm labor, and chorioamnionitis. The patient passed melena containing blood clots after the delivery. After the last pregnancy, laparoscopy and laparotomy revealed an ileal-uterine fistula and a foreign body (necrotic cartilage). The blind loop of bowel was resected and the fistulous tract excised. CONCLUSION: Our patient's recurrent pregnancy wastage was caused by chorioamnionitis secondary to an enterouterine fistula resulting from foreign body ingestion. A complete reversal of this problem is anticipated.
