Diagnosis

• In almost all cases, doctors first choose to perform a barium contrast study of the small intestine.



• Upper GI tract endoscopy may be useful in detecting areas of concern in the immediate upper GI tract.



• A CT scan of the abdomen or an abdominal ultrasound may help to visualize bulky tumors and to rule out any spread of the cancer to adjacent lymph nodes and distant organs such as the liver.



• Colonoscopy may help diagnose tumors involving the lower areas of the small bowel.
