NCT ID: NCT04952142 Completed - Clinical trials for Water Exchange Colonoscopy

Minimal Water Exchange Versus Left Water Exchange in Unsedated Colonoscopy

Start date: April 22, 2021
Phase: N/A
Study type: Interventional

Minimal water exchange colonoscopy is theoretically more convenient and faster than water exchange colonoscopy. But few studies compared the differences between the two methods. Therefore, we attempted to evaluate the effect of minimal water exchange colonoscopy prospectively.

NCT ID: NCT03832322 Completed - Colonic Adenoma Clinical Trials

Adenoma Miss Rate With Water Exchange vs Carbon Dioxide Colonoscopy

Start date: July 9, 2018
Phase:
Study type: Observational

This was an observational study comparing consecutive group of WE and CO2 insufflation in terms of right and proximal colon AMR by tandem colonoscopy.

NCT ID: NCT03160859 Completed - Clinical trials for Water Exchange Colonoscopy

Prospective RCT Of Water Exchange (WE) vs. WE Plus Cap-Assisted Colonoscopy

Start date: June 8, 2018
Phase: N/A
Study type: Interventional

This is a study to compare two different, but normally, used methods of colonoscopy in patients undergoing colonoscopy without sedation. There will be two arms in this study: WE (water exchange) control, and WE (water exchange) plus cap (placed at tip of the colonoscope). The patient will prepare himself/herself for the colonoscopy as per normal instructions and he/she will be given the information for the study at that time so that he/she can make a decision to participate in the study. The control method will use water instead of air during insertion of the colonoscope. The study method will use a cap that will fit onto the end of the colonoscope plus water during insertion of the colonoscope. This study will assess if the study method is less painful than the control method.

NCT ID: NCT02665741 Completed - Colon Polyps Clinical Trials

Comparison of Colon Adenoma Detection Rate Using Two Distal Colonoscope Attachments

Start date: January 2016
Phase: N/A
Study type: Interventional

The goal of this study is to compare two FDA approved distal colonoscope attachment devices, in order to identify which device can increase adenoma detection rate the most without increasing procedure time or risk.
