An interventional study of Water jet channel and Accessory channel in Colonoscopy and Colon Disease, sponsored by Chih-wei Tseng. Completed at 1 site in Taiwan. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2019-10-29.

This prospective randomized controlled trial compared integrated water jet channel colonoscopy with traditional accessory channel colonoscopy in cecal insertion time among patients undergoing WE method colonoscopy.
When the WE method colonoscopy were done with the accessory channel for both infusing and suctioning of water. The water had to be suctioned or infused alternatively and increaed the insertion time.
With the new designed endoscopy that integrated a separate water jet channel for infusing water, infusing and suctioning of water can be done at the same time. Besides, water jet pumping system could provide a powerful jet to help us open the collapse lumen and keep an appropriate distance between the mucosa and the lens, thus preventing loss of visualization. It will help the colonoscopist to find the way during insertion.
Exclusion Criteria:
The colonoscopy was done with the new designed colonoscopy that integrated a separate water jet channel for infusing water. The dirty water was removed through other accessory channel.
Device: Water jet channel · Device: Accessory channel
The colonoscopy was done with the traditional colonoscopy. Water exchange was done by using the accessory channel for both infusing and suctioning of water.
Device: Accessory channel
The separate water jet channel was used for infusing water.
The accessory channel was used for infusing and/or suctioning water
cecal insertion time
Cecal insertion time was defined as the time from insertion into the rectum to the time when the colonoscope tip passed to a point proximal to the ileocecal valve so that the base of cecum was visible.
Time frame: 2 hours
