Diagnosis of Bezoars
Imaging tests Endoscopy Often, a bezoar can be seen on imaging tests, such as X-Ray Studies of the Digestive Tract , Usually, Endoscopy (a visual examination of the digestive tract using a flexible tube called an endoscope) is done to confirm the diagnosis of a bezoar and to exclude a tumor as the cause. During the endoscopy, doctors may remove a piece of a bezoar and examine it under a microscope to see what it is made of, such as hair or plant material. Doctors may try to break the bezoar into pieces and remove it during endoscopy.
