Endoscopy is a method of diagnostic imaging that allows for visualization of internal organs without invasive surgery. It is commonly used to image the esophagus and gastrointestinal (GI) tract (upper or lower endoscopies, colonoscopy), nasal cavity (rhinoscopy), lungs (bronchoscopy), vagina and bladder (including urethra and ureters) (cystoscopy), and joints (arthroscopy).  Endoscopy may also be used to explore the abdomen laparoscopically through very small incisions. Biopsy samples are obtained during imaging and foreign objects (such as a rawhide lodged in the esophagus), can possibly be retrieved without resorting to surgery.


Endoscopes come in flexible and rigid forms which are used for different types of imaging.  In general, the flexible scopes are used for imaging the esophagus, GI tract, and the lower respiratory airways with a rigid scope used for other imaging such as the bladder or nasal passages. 


The endoscope has a tiny camera at the end so the Doctor sees an image of your Pet’s tissue.  A small channel runs down the scope and a very small biopsy instrument may be inserted to acquire a sample to be submitted for review by a pathologist or for other diagnostic testing.


For their safety and comfort, your Pet will be placed under general anesthesia to perform an endoscopic procedure. During the procedure, your Pet’s vital signs (heart rate, respiratory rate, temperature, and others) are closely monitored.  Your Pet will need to fast for several hours prior to general anesthesia; endoscopy of the GI tract may also require administration of enemas to totally empty the GI tract and allow complete visualization of it.  Many Patients may go home the same day but for some, the Doctor may recommend they stay overnight with CVSEC to more thoroughly support their recovery from anesthesia and the procedure.


 The Doctor will give an initial assessment of the endoscopic procedure and call once we receive results of any diagnostic testing, which may take several days.
