Effectiveness and Safety of the Colonoscopy With "Visualization" Balloon
A Randomized Controlled Trial to Evaluate Effectiveness and Safety of the Colonoscopy With the "Visualization" Balloon
Colonoscopy has become the "gold standard" in detection of colonic polyps and colon cancer. However, colonoscopy causes significant abdominal discomfort and abdominal pain during and after the procedure, requiring intravenous sedation and use of analgesics. The discomfort and pain are mostly caused by air insufflation and intubation difficulties during advancement of the colonoscope in order the reach the cecum.
Study Hypothesis: Use of the "Visualization" Balloon will facilitate advancement of the colonoscope and will eliminate the need for colonic distention with the air or CO2, which can shortened the length of the procedure, reduce patient's discomfort and can decrease amount of sedatives and analgesics used during colonoscopy.
調査の概要
詳細な説明
The goal of this study is to evaluate effectiveness and safety of a "Visualization" Balloon for performance of colonoscopy.
Our hypothesis is that, use of "Visualization" Balloon will decrease colonic distention, patient's discomfort, use of sedatives and analgetics during procedure and will simplify the performance of colonoscopy resulting in shortening of procedure time and increasing the rate of cecal intubation.
Specific aims of the study:
- To compare procedure time and effectiveness of the "Visualization" Balloon colonoscopy with traditional CO2-insufflation colonoscopy.
- To compare safety profiles between traditional CO2-insufflation colonoscopy and colonoscopy using the "Visualization" Balloon.
4 STUDY ENDPOINTS 4.1 Primary Outcome To compare the mean cecal intubation time achieved with "Visualization" Balloon colonoscopy, with the mean cecal intubation time achieved with standard colonoscopy using CO2 insufflation.
4.2 Secondary Outcomes
To compare "Visualization" Balloon colonoscopy with standard CO2-insufflation colonoscopy in regards of:
- Total amount of carbon dioxide (CO2) gas for colonic insufflation used during the procedure.
- Ease of colonoscope insertion.
- The length of the colonoscope when it reaches the cecum. 4 Colonoscope withdrawal time and total procedure time.
5. Cecal intubation rate. 6. Total dosage of analgesics and sedative during procedure. 7. Patient satisfaction: perceived pain and discomfort immediately after the procedure and in 24 hours post procedure.
8. Complications during and after colonoscopy. 9. Polyp detection rate.

Inclusion Criteria:
- The patient is undergoing colonoscopy for colo-rectal cancer screening, polypectomy or for diagnostic workup.
- Subject is able to understand the risks and benefits of participating in the study and must be willing to sign and date the Informed Consent Form for this study approved by the Institutional Review Board (IRB.)
- Age from 17 to 90 years.
- Be willing and able to comply with the requirements of the protocol.
- Be willing to refrain from participating in any other investigational interventional study while enrolled in this study.
- Female subjects must have a negative pregnancy test within the last 24 hours timeline and have no intentions of becoming pregnant during participation in the study, or be sterilized.
Exclusion Criteria:

実験的：Visualization balloon
Colonoscopy performed with the use of "Visualization" balloon
|
The "Visualization" Balloon is a disposable medical device that is used during the advancement of the colonoscope inside the colon.
The intended use of the "Visualization" Balloon is to help insertion of the colonoscope into the colon without the aid of gas (air or CO2) insufflation as with standard colonoscopy.
The "Visualization" Balloon is inserted through the biopsy channel of the colonoscope prior to the colonoscope introduction into the rectum.
The "Visualization" Balloon is an inflatable balloon that opens up the lumen of the gastrointestinal tract, thereby allowing the endoscopist to advance the endoscope inside and to view the gastrointestinal tract through the clear balloon.
