What is Endoscopy?

  • An endoscope is tube (flexible or rigid) with a light and camera at the end
  • Endoscopy is a procedure where an endoscope is passed into a certain part of the body to visualize the inside of structures, obtain samples for diagnoses and occasionally treat problems

Applications for Endoscopy

Down the Hatch

  • Upper GI endoscopy uses the flexible scope to go into the esophagus, stomach and the proximal small intestine
  • Foreign body retrieval from the esophagus or stomach
  • Visualization for inflammation (esophagitis, gastritis) and tumors
  • Obtaining biopsies for diagnosis – cancer, inflammatory bowel disease, autoimmune conditions

Know the Nose

  • Flexible Endoscopy is used to view the nasopharynx (throat and back of the nose)
  • Rigid Endoscopy is used to view the front of the nose
  • Useful in visualizing for tumors, foreign bodies and nasal mites
  • Can obtain biopsies for diagnosis of cancers, infections (fungal disease) and inflammatory conditions

Bringing up the Rear

  • Colonoscopy can visualize the large intestinal for polyps, tumors, and inflammatory conditions
  • Again – biopsies can be obtained to make a diagnosis

Take a Deep Breath

  • Bronchoscopy involves using the flexible scope to go down the trachea and into the mainstem bronchi
  • It can be useful for obtaining Bronchoalveolar Lavage samples (washes of the lower airways) for diagnosis and culture

The Urination Station

  • Cystoscopy uses the rigid scope to look up the urethra and into the bladder in the female dog
