Colonoscope Insertion Trial Protocol

November 30, 2017 updated by: Joseph Anderson, UConn Health

Study to Examine Insertion of 2 Colonoscopes Trial

This research study is about determining how well a Technically Improved Colonoscope from Olympus works in helping the doctor in guiding the scope through the large bowel or colon. When a doctor performs a colonoscopy he guides or inserts the scope from the rectum to the appendix where the small bowel ends and the large bowel begins. There are points during this insertion where there are turns in the colon which can create a loop in the colonoscope. These loops can stretch the colon and create some discomfort and also require special maneuvers by the nurse or patient to help reduce or minimize the loop. Thus, reducing the looping will make it more comfortable for the patient and more efficient for screening for polyps. The purpose of the study is to examine this colonoscope and compare it to the traditional adult colonoscope (Olympus CF-H180). The investigators hypothesis is that this colonoscope will function better with regard to insertion of the scope from the rectum to the cecum.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There will be two arms to the study, the CF-H180 adult colonoscope (Control Arm) and the Olympus Technically Improved Colonoscope (Olympus). (Control Arm). In this protocol the investigators will randomize patients to either the adult colonoscope or to the Olympus Technically Improved Colonoscope (Olympus) arm. The name of the arm (CF-H180 adult colonoscope or Technically Improved Colonoscope) will be in a sealed envelope and opened by the nurse. The endoscopist will be blinded to the scope that will be used.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

35 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients presenting for outpatient colonoscopy between the ages of 35 and 75 years of age
  • The patient population will be open. However, it is known that thin female patients (BMI < 25) and/or past history of diverticular disease and/or gynecological surgery and men & women who are tall (6'+) and patients with constipation are usually difficult candidates for a complete colonoscopy (retroflex in the cecum)
  • Adequate bowel preparation
  • The ability to provide informed consent

Exclusion Criteria:

  • Women that are pregnant
  • Patients with a past history of inflammatory bowel disease
  • Patients with a past history of surgical resection (hemicolectomies, etc)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time to Intubate the Cecum
Time Frame: The outcome was measured during the colonoscopy which was Day 1. The duration of the study was the colonoscopy on Day 1. Once the colonoscopy was finished, the study was over.
The time in seconds that it required to intubate the cecum as defined in our protocol.
The outcome was measured during the colonoscopy which was Day 1. The duration of the study was the colonoscopy on Day 1. Once the colonoscopy was finished, the study was over.
Intubation of Cecum
Time Frame: (day 1) Within time for performance of colonoscopy
The ability of endoscopist to intubate the cecum with enough control of the tip to abut the appendix or begin to retroflex in the cecum.
