Comedian Joan Rivers was rushed to a NY area hospital where she is listed in stable condition after she stopped breathing while undergoing a routine endoscopic procedure at an outpatient clinic. An endoscope is a small, flexible tube with a camera and a light at the end of it. The endoscope is passed down a patient's throat by doctors who look for abnormalities (tumors, ulcers, etc.) in the patient's esophagus or the stomach.
Rivers, 81, is pictured above with the late Robin Williams.
