Introduction

Endoscopy is the use of an instrument (i. e., the endoscope) to look into a cavity or orifice. Its main value to veterinary gas­troenterology consists of allowing the collection of tissue samples without surgery, although observation of morpholo­gical changes of the mucosal surface or removal of foreign bodies is also useful. Gastroduodenoscopy is the most impor­tant flexible endoscopy technique, although colonoileoscopy can also be important.
