Types of Procedures

Endoscopy/ Colonoscopy

Endoscopy is a non-invasive, non-surgical diagnostic tool used to visualize the gastrointestinal tract. While animals are under general anesthesia with continuous monitoring, the flexible scope (encased fiber optic cables) will be inserted through the oral cavity (endoscopy) or rectum (colonoscopy) to visualize the tissues for any abnormalities or irregularities. In an endoscopy, the mouth, throat, esophagus, stomach, and upper part of the small intestine can be reached. Colonoscopies are useful to visualize the rectum, large intestine, and last part of the small intestine. The scope is equipped with a light source and camera to visualize the tissues clearly, projecting onto a monitor in a continuous video fashion. With this tool, tiny samples (biopsies) can be collected in order to diagnose any abnormalities of the tissue. Endoscopy can also be used to diagnose and, sometimes, even non-invasively remove foreign objects from the gastrointestinal tract without surgery.

Diseases or clinical signs that may benefit from an endoscopy or colonoscopy include:

  • Weight loss
  • Difficulty swallowing
  • Changes in bowel habits
  • Vomiting
  • Diarrhea
  • Constipation
  • Chronic gastroenteritis
  • Gastric ulceration
  • Inflammatory bowel disease
  • Colonic polyps
  • Gastrointestinal foreign objects and/or obstruction


Rhinoscopy is a non-invasive, non-surgical diagnostic tool used to visualize the nasal passages. This scope is rigid in nature and has a light and camera as well. Samples may also be taken in the nasal passages with this tool to diagnose and abnormalities such as nasal tumors, chronic inflammation, infectious sinusitis, or foreign objects.

Clinical signs that may benefit from a rhinoscopy include:

  • Bloody nasal discharge
  • Chronic nasal discharge
  • Chronic sneezing
  • Difficulty breathing
