About this study

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.

Inclusion criteria

  • Underwent fully sedative colonoscopy with WE method in the outpatient department

Exclusion criteria

  • Age < 18 years old or > 80 years old
  • Without standard colon preparation
  • Allergy to meperidine or propofol

Treatment and study plan

Water jet channel

Device

The separate water jet channel was used for infusing water.

Accessory channel

Device

The accessory channel was used for infusing and/or suctioning water

Primary outcomes

  1. cecal insertion time

    Time frame: 2 hours

    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.
