A member asked:

Was referred to gastroenterologist for positive fit test (occult blood). was told to do egd/colonoscopy but i refused the tests. anything uninvasive?

A doctor has provided 1 answer

Noninvasive: Noninvasive studies of the colon include a virtual colonoscopy involving ct scanning and an air contrast barium enema. For study of the esophagus and stomach, a barium swallow and upper gi series can be done. However these older studies may miss smaller lesions.
