The intestinal atresia is a common cause of neonatal bowel obstruction, but the colonic atresia is an uncommon cause of neonatal intestinal obstruction. We present a newborn with congenital colon atresia who underwent laparotomy, revealing a colonic atresia type III. We recommend resection of the dilated proximal colon with primary anastomosis end to end if the patient is not perforated or in bad general conditions.
