Research summary
The colonoscopy procedure involves insertion of a thin, flexible tube with a tiny camera inside (colonoscope) passed inside the bowel. To allow passage of the colonoscope and adequate visualisation of the lining of the bowel wall a range of techniques can be used. Water or gas can be inserted into the colon during the procedure in order to open up the collapsed bowel wall to give good views.
In recent years, there is growing evidence that using water, rather than gas may offer benefits in terms of comfort during procedures and being able to find polyps. Very few studies have looked at using a combination of both water and gas during the procedure which is the most widely used technique for performing colonoscopy.
Our aim is to assess whether the use of water on insertion of the colonoscope is a more comfortable and efficient method of performing a colonoscopy rather than using a combination of water and gas.
