Colonoscopy Clinical Trial
Official title:
Division of Gastroenterology, Department of Internal Medicine, Dalin Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Chiayi, Taiwan
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.
