Introduction:

Congenital abnormal bands (CAB) have different abdominal manifestations in children. Diagnosis and treatment are surgical.

Clinical case:

A five-year-old patient with history of episodes of intestinal obstruction from 16 months of age, which were resolved by conservative management, despite requiring hospitalization. Hirschsprung’s disease was suspected, but studies were not performed to confirm the diagnosis. For acute abdomen was taken to surgery; during the procedure we found a CAB, which caused internal hernia and dilated intestinal loops. We proceeded to perform the CAB resection and end-to-side anastomosis. Subsequently, the patient had adequate clinical evolution.

Conclusions:

The diagnosis of CAB can be difficult, given the nonspecific clinical picture and because imaging studies are not useful. Thus, CAB should be part of the differential diagnosis in children with evidence of intestinal obstruction.
