how long does it take to have a colonoscopy and egd on the same day
Endoscopy can take from 15-30 minutes. The procedure can take more or less time and varies from person to person. The patient will be in the Operating Room for 20-45 minutes for an upper endoscopy, and 30-120 minutes for a colonoscopy. Many patients have both an upper endoscopy and colonoscopy under the same anesthesia, which takes 40-120 minutes. http://www.cincinnatichildrens.org/health/info/abdomen/procedure/gi-endoscopy.htm. I had an endoscopy last month and the actual proceduare was only about 10 min because it was normal.
