endoscopy

noun

1. The examination of a bodily orifice, canal or organ using an endoscope.

   “But less complex scopes also pose contamination risks – and they’re used on far more people: Each year in the United States, doctors perform more than 15 million colonoscopies and 7 million endoscopies of the upper GI tract.”

   “One insurance company, UnitedHealthcare, has announced that starting in June, members with commercial plans seeking gastroenterology endoscopy services – including colonoscopies – will be required to have “prior authorizations” for those services.”
