Congenital colonic stenosis: a case of late-onset.
OBJECTIVE
Colonic atresia and stenosis are rare causes of intestinal obstruction in the infant. Only 1.8%-15% of intestinal atresias occur in the colon. Congenital colonic stenosis is even less common than colonic atresia. Only 10 cases have been reported in Literature since 1966 and only one late-onset case has been reported in Literature until now. We describe the case of a 4-month-old baby coming to our attention because of an intestinal subocclusion due to a congenital colonic stenosis of the ascending colon.


METHODS
A 4-month-old baby came to our attention for persistent abdominal distension, reduction of bowl function and decaying of overall clinical conditions. A plain abdominal radiograph showed distended intestinal loops with air-fluid levels and no gas in the rectum. During the barium enema the contrast medium appeared to completely fill the lumen of the colon up to the ileo-cecal valve and Cecum appearing higher than normal. Beyond the ileo-cecal valve, the contrast medium showed an abnormal hypotonic dilatation of the small intestinal loops. Suspecting an organic intestinal obstruction, an explorative laparotomy was deemed necessary and at halfway in the ascending colon a stenosis was found.


RESULTS
The post-operative course was uneventful and the patient is currently in good clinical conditions, has a normal diet and is thriving.


CONCLUSIONS
Considering both the Literature and our own experience, it is wise to reckon the congenital colonic stenosis as a rare but possible cause of complete or partial intestinal obstruction not only in the newborn but also throughout the first year of life.
