Endoscopic diagnosis of diseases causing vomiting.

Animals that are chronically throwing up can be diagnostic challenges. Endoscopy can be a useful adjunct in the diagnostic and therapeutic approach to many of these patients; however, it is critical that endoscopic examinations be done properly and carefully. Poorly performed endoscopic examinations can miss important lesions, especially when poor biopsy technique results in inadequate tissue samples for the pathologist. Likewise, rough technique (especially when trying to remove foreign objects) can harm the patient.
