The most common ultrasound findings were dilated bowel\/stomach (77.3%), polyhydramnios (30.7%) and whirlpool\/snail sign (28.4%). Median gestation at diagnosis was 31.9\u00a0weeks (IQR 27\u201334) and mean gestation at delivery was 34.5\u00a0weeks (SD 2.8). Underlying aetiology included intestinal malrotation (15.9%), cystic fibrosis (14.8% of all cases, 32.5% of tested cases) and abnormal mesenteric fixation (12.5%).
