Ultrasonographic features of fetal gastric duplication / 中华超声影像学杂志

ABSTRACT

Objective To analyze the ultrasonic and clinical features of fetal gastric duplication. Methods Ultrasonographic apperance of 12 fetal stomach duplication cases were reviewed and followed up. Results The age of 12 fetal gestational duplication cases ranged from 19 weeks to 36 weeks. All cases were cystic-type,and 11 cases of gastric duplication were diagnosed by antenatal ultrasonography. Eleven cases were normal labored,2 patients were cured after surgical management. One case was misdiagnosed to be bile duct cyst, and was induced in 1 week after diagnosis because of simultaneous combination of hydrocephalus in bilateral ventricle. Stomach duplication prenatal sonographic findings were cysts near the stomach with thickened wall in local enlarged images. The cystic wall included 3 layers of strong-weak-strong hierarchical structure as normal stomach wall. Conclusions Fetal stomach duplication has characteristic ultrasound features,and can be definitively diagnosed prenatally. Early diagnosis is of great importance for prenatal consultation and timely treatment after birth.
