What is a panendoscopy?
Panendoscopy is a diagnostic test used to examine the upper digestive system, including the esophagus, stomach and first part of the small intestine. In this exam, an individual is given general anesthesia in an operating room so that the entire region of the body can be closely inspected for cancer. Endoscopes are used to look at the throat, larynx, esophagus and possibly the windpipe (trachea) and bronchi.
Panendoscopy for head and neck cancer
If your doctor suspects the presence of head and neck cancer, this more thorough exam will most likely be performed. If any tumors are found, your doctor will remove samples that can be looked at under a microscope.
