Core Tip
Core tip: Gastrocolic fistulas (GFs) are rare, occult and potentially life-threatening complications in Crohn’s disease (CD), which can indicate the active status of CD and predict a future surgery within a short period. Ultrasound is one of the first-line modalities to evaluate CD. Oral agent contrast-enhanced ultrasound (OA-CEUS) may be helpful in reducing the possibility of a missed diagnosis of GF. Only a few cases of GF have been reported in the current literature. Surgery is the definitive treatment for GF. It is important to identify and manage GF in a timely manner. This paper describes a GF secondary to CD detected by OA-CEUS when endoscopy and computed tomography missed the diagnosis.
