Perforation cæcale néonatale inaugurale du diagnostic d’un mégacôlon congénital

Spontaneous intestinal perforations are rare in a full term new-born. We report the case of an infant born at 41 weeks’ gestation who, three days after birth, had pneumoperitoneum revealing congenital megacolon. Surgical exploration showed diastatic perforation of the cecum associated with a disparity in rectosigmoid caliber. The patient underwent emergency caecostomy after peritoneal washing. Histological examination of the biopsy specimens confirmed the diagnosis of congenital megacolon. The postoperative course was simple and radical treatment was performed six months later.
