An endoscope is composed of a long thin tube, a light source, camera and viewing eyepiece. In addition, there are two channels within the tube. One is for passing instruments, allowing for the removal of foreign objects, a collection of biopsy samples and removal of small polyps or tumors. Air or water can be passed through the other channel for better viewing of the tissue or organ.
The endoscope allows your veterinarian to diagnose and treat a variety of gastrointestinal disorders. Depending on the symptoms, it is used to look at the inner lining of the esophagus, stomach, intestine, and colon. Endoscopy is used to obtain biopsies, look for cancer of the esophagus or stomach and to remove foreign bodies from the stomach without surgery.
Even though general anesthesia is required for an endoscopic procedure, it is much less invasive for your pet than traditional surgery. The procedure takes less time, there is no surgical incision and there is a low occurrence of complications.
