Austin and Homsy attempted to streamline the antenatal diagnosis of cloacal exstrophy by a retrospective analysis of antenatal scans of affected patients. Features present in more than 50% of cases (major criteria) include nonvisualization of the bladder, a large midline anterior abdominal wall defect or a cystic anterior wall structure, a large omphalocele, and myelomeningocele. Features present in less of 50% of cases (minor criteria) are ascites, lower extremity de-
fects, renal anomalies, widened pubic arches, narrow thorax, hydrocephalus, and a single umbilical artery . In 1999, Hamada et al. added the visualization of the elephant trunk-like protrusion of the proximal midgut as a minor criterion .
At the Fetal Care Research Foundation in Chennai India, 57,993 pregnancy ultrasound scans were performed between January 1998 and December 2004, and 5,825 anomalies were detected. Twenty-five fetuses were noted to have the body stalk anomaly, 7 had vesical exstrophy, and 5 were antenatally detected to have cloacal exstrophy. In a retrospective review of these latter five ultrasounds, the following were identified: omphalocele (4/5), nonvisualization of the bladder (4/5), lower-limb anomalies (4/5), infraum-bilical body wall defect (4/5), renal anomalies (3/5), meningomyelocele (2/5), narrow thorax (2/5), single umbilical artery (1/5), hydrocephalus (1/5), ascites (1/5), and widened pubic arch (1/5). Prolapse of the small bowel, giving the elephant-trunk deformity, was noted in one case (Fig. 14.2).
