Prenatal sonographic findings in a fetus with congenital isolated ileal atresia.

Most cases of isolated nonduodenal bowel atresia are thought to be due to ischemic events from hypotension, vascular accident, volvulus, intussusception and cocaine. We present a case of isolated ileal atresia suggested using results of prenatal sonography which showed multiple markedly dilated fluid-filled intestinal loops with changeable shapes and positions secondary to active peristalsis. Postnatal oral contrast radiography demonstrated obstruction located at the ileal level. Exploratory laparotomy confirmed isolated ileal atresia. Primary end-to-end anastomosis was done. The infant endured the procedure well. Cases with multiple intestinal atresia always have fatal prognosis, even after surgery. Cases of isolated intestinal atresia usually have better prognosis and deserve more attention. Early diagnosis and early intervention are both important for good outcomes.
