Symptoms
Adenocarcinoma may cause bleeding into the intestine, which shows up as blood in the stool, and obstruction, which in turn may lead to crampy abdominal pain, expansion (distention) of the abdomen, and vomiting.
A doctor may use an endoscope (a flexible viewing tube) passed through the mouth and down to the duodenum and part of the jejunum (the upper section of the small intestine) to locate the tumor and perform a biopsy (remove a tissue sample for examination under a microscope). A doctor can sometimes see tumors of the ileum (the lower section of the small intestine) by passing a colonoscope (an endoscope used to view the lower part of the digestive tract) through the anus, through the entire large intestine, and up into the ileum. A barium x-ray can show the entire small intestine and may be used to outline the tumor. A wireless video capsule camera can also be used to show tumors of the small intestine. Arteriography (an x-ray taken after a radiopaque dye is injected into an artery) of the intestinal arteries may be performed, especially if the tumor is bleeding. Similarly, radioactive technetium can be injected into the artery and observed on x-rays as it leaks into the intestine. This procedure helps locate sites where the tumor is bleeding. The bleeding can then be corrected surgically. Sometimes exploratory surgery is needed to identify a tumor in the small intestine.
