Summary

This trial is testing a new method for colonoscopy that uses water and a small cap to make the procedure less painful and more effective for veterans. The water method for colonoscopy, which involves water infusion instead of air, has been shown to reduce patient discomfort and sedation requirements in several studies.

Who is the study for?
This trial is for male and female Veterans who opt for unsedated colonoscopy, whether it's for screening, diagnosis, or surveillance. Participants must be able to consent and complete questionnaires. Those with a history of certain abdominal surgeries, current heavy medication use, or conditions that complicate colonoscopy are excluded.
What is being tested?
The study compares two methods during a colonoscopy: the Water Exchange (WE) method alone versus WE plus Cap-assisted Colonoscopy (WECAC). The goal is to see if adding a cap reduces pain more than WE alone and if it improves the procedure time and detection rate of adenomas in the proximal colon.
What are the potential side effects?
While not explicitly listed in your information provided, typical side effects from these procedures may include discomfort or mild pain due to gas insufflation, bloating, cramping sensations during insertion of the scope or when using water exchange techniques.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: WE plus cap(WECAC)Experimental Treatment2 Interventions
The procedure of this group is similar with WE group, except a cap will be fitted onto the end of the colonoscope.
Group II: Water exchange (WE)Active Control1 Intervention
This group will have the air in the colon removed and replaced with water to guide the insertion of the colonoscope.

Other Research
The Water Exchange (WE) method reduces Real-time Maximum Insertion Pain (RMIP) by infusing water instead of air during colonoscope insertion, minimizing bowel distension and discomfort. Cap-Assisted Colonoscopy (CAC) adds a cap to the colonoscope, aiding in smoother navigation and reducing mucosal trauma. These techniques are important for RMIP patients as they enhance comfort during the procedure and improve adenoma detection rates, which is vital for effective colorectal cancer screening.
