If you're having keyhole surgery (laparoscopy), the endoscope will be inserted into a small incision your surgeon makes in your skin. An endoscopy usually takes between 15 and 60 minutes, depending on what it's being used for.
The colonoscopy itself only takes about 30 minutes. The prep begins at home the evening before the procedure. The morning of your colonoscopy youll spend about three hours at the clinic or hospital. Then youll return home to rest for the remainder of the day. You can usually return to your usual activities the next day.
