Abstract: An intestinal fistula is defined as an abnormal passage that connects the intestine to another intra-abdominal organ,the abdominal cavity,or the body surface.Due to the presence of intestinal contents,digestive enzymes,bacteria,and fecal matter,intestinal fistulas can lead to severe complications such as sepsis and short bowel syndrome (manifested by dehydration,electrolyte imbalances,and malnutrition).The etiology of intestinal fistulas can be broadly classified into four categories:postoperative,traumatic,disease-related,and congenital.Among these,the first three are more commonly encountered,whereas congenital intestinal fistulas are relatively rare.

Key words: enterocolic fistula, congenital, pediatric, diagnosis and treatment
