Clinical Trial Summary

This research study compares two methods of performing colonoscopy without sedation. The standard method is to insert the colonoscope without adding any water to the colon, and when colonic spasms occur during the examination, waiting for the spasms to subside before continuing with the insertion of the colonoscope. The study method involves putting 200 ml (7 oz) of warm water through the colonoscope into the colon at the beginning of the examination, and when colonic spasms occur during the examination, putting 30 ml (1 oz) of warm water into the spastic area(s) to relax the colonic spasms.


Description:

The purpose of the study is to conduct a RCT study to determine the effectiveness of loading the sigmoid colon with warm water and warm water irrigation for dealing with colonic spasms in enhancing patient abdominal comfort during unsedated colonoscopy. The specific aim is to compare Study Treatment of warm water loading and irrigation when spasms occur with Control Treatment of no water loading and waiting for spasms to subside. The proportion of patients complaining of abdominal discomfort and their discomfort score are the primary outcome variables. The secondary outcome variables and co-variables described below will be recorded in a prospective manner to ensure completeness of data collection. In preliminary clinical observation at VA Sepulveda ACC, 25 to 30% of VA patients accept colonoscopy without sedation. The goal of this study is to find ways of further reducing discomfort associated with unsedated colonoscopy.

Gender All
Age group 18 Years to 80 Years
Eligibility Inclusion Criteria:

- Adult male and female

- Adult patients 18 years old in need of colonoscopy for screening or follow up of colonic polyps, and willing to consent to be randomized.

Exclusion Criteria:

- Patients receiving outpatient prescription narcotic treatment [more likely to have discomfort response even with sedation (42)].

- Patients who report excessive anxiety [pre-endoscopy appointment, single question asking how anxious the patient generally is, four point scale (1 = not at all, 2 = slightly, 3 = moderately, 4 = excessively].

- Excessive anxiety is significantly correlated with lack of cooperation during colonoscopy and high dissatisfaction score after the procedure (43).

- Patients with moderate to severe abdominal discomfort, unable to provide informed consent, have a poor bowel preparation (discolored rectal output or feces filled rectal vault), and those who decline to participate, will also be excluded.
