Can Simple and Inexpensive Techniques Enhance Patient Comfort

This research study compares two methods of performing colonoscopy without sedation. The standard method is to insert the colonoscope without adding any water to the colon, and when colonic spasms occur during the examination, waiting for the spasms to subside before continuing with the insertion of the colonoscope. The study method involves putting 200 ml (7 oz) of warm water through the colonoscope into the colon at the beginning of the examination, and when colonic spasms occur during the examination, putting 30 ml (1 oz) of warm water into the spastic area(s) to relax the colonic spasms.
