Imperforate anus associated with atresia of the transverse colon: a case report

We describe here a rare case of association of imperforate anus with transverse colon atresia in a male neonate. Preoperative X-ray studies demonstrated: a) a distended loop in the epigastrium with fluid levels on plain A/P upright radiography, b) absence of pelvic intestinal gas on the invertogram 16 hours later. A three-stage operative approach was undertaken comprising resection of the atretic loop and colostomy, posterior sagittal anorectoplasty a few months later, and finally closure of the colostomy. The postoperative outcome was good. The association of these anomalies should be kept in mind in neonates with anal atresia and abdominal distention.
