RESUMO
OBJECTIVE: To investigate the prenatal ultrasonographic manifestations of fetal congenital omphalo-enteric fistula with intestinal prolapse and improve the understanding and diagnosis of this disease.METHODS: A retrospective analysis of the prenatal ultrasonographic features was performed in 2 cases of fetal congenital omphalo-enteric fistula with intestinal prolapse comnfirmed after surgery between July 2016 and September 2017 in First Affiliated Hospital of Fujian Medical University,and the ultrasonographic manifestations were compared with postnatal looks and intraoperative conditions.Characteristics of prenatal ultrasonographic manifestations were summarized.RESULTS: Both cases were misdiagnosed as omphalocele by prenatal ultrasonography.Congenital omphalo-enteric fistula with intestinal prolapse was verified by surgery after delivery.A narrow pedicle,special bowel-shape and incomplete capsule were its prenatal ultrasonic characteristics.CONCLUSION: Fetal congenital omphalo-enteric fistula with intestinal prolapse is rare,but has particular prenatal ultrasonographic manifestations. Strengthening the understanding of the disease,reducing misdiagnosis and improving prenatal ultrasound diagnosis will provide help for prenatal counseling and clinical choice for time of delivery.
