Abstract

|
|
Necrotizing enterocolitis is a severe inflammatory disease of the intestine and is the main cause of death in infants, mostly occurring in premature infants. Intestinal obstruction may occur during the medical treatment of necrotizing enterocolitis. A common cause of intestinal obstruction is intestinal stricture, and entero-enteric fistulas may form in the proximal portion of the intestinal stricture. Several mechanisms may be suggested for the development of entero-enteric fistula. Intestinal ischemia and subsequent necrosis do not become intestinal perforation over time, causing an inflammatory reaction, and are attached to the adjacent intestine, forming a fistula. Alternatively, a subacute perforation may be sealed off by the adjacent intestine, resulting in fistula formation. Entero-enteric fistulas are closely related to distal stricture and occurs when there is a localized perforation rather than a generalized perforation. Fistulas can be diagnosed via contrast enema examination or distal loopogram, and surgical resection is required. Here, I report a case of a preterm infant with an entero-colonic fistula secondary to necrotizing enterocolitis. The patient had abdominal distention and bloody stool and was confirmed to have rotavius enteritis. Plain abdominal radiographs showed pneumatosis intestinalis. The patient received medical treatment for necrotizing enterocolitis. While the symptoms were improving, he vomited again, and intestinal obstruction was suspected.
Gastrografin enema was performed due to intestinal obstruction, and an enterocolonic fistula was found.
