A thin flexible tube with a camera is inserted in the mouth to see the esophagus, stomach, and first part of the small intestine while the child is under general anesthesia, usually as an outpatient. The test is used to diagnose eosinophilic esophagitis, gastroesophageal reflux, celiac disease, peptic ulcer disease, gastric infections and inflammatory bowel disease. It’s also used to look for causes of poor growth, and regurgitation. Small pieces of tissue, about the size of a pinhead, are usually taken for testing under the microscope. Through this approach, the doctor is able to actually see inside the GI tract to determine possible problem areas.
A flexible tube with a camera is used to look into the last part of the intestines (colon and terminal ileum). The test helps evaluate polyps, inflammatory bowel disease, and other causes of gastrointestinal bleeding. Small tissue samples, the size of a pinhead, are taken. Polyps, which are growths of tissue lining the intestines, might also be removed. The test is done with general anesthesia, usually as an outpatient.
Imaging tests, performed at hospitals or imaging centers, include X-rays (upper GI series, swallowing evaluations), ultrasound, MRI (magnetic resonance imaging), CT (computerized tomography) and nuclear medicine tests.
