Brief Summary

The purpose of this study is to evaluate the effect of the PCCE preparation and procedure on colon cleansing level and excretion rate.

Detailed Description

The evaluation of subjects with suspected colonic disease includes endoscopic imaging by colonoscopy and radiologic imaging such as air-contrast barium enema, or CT colonography. The PillCam® platform offers an alternative approach for endoscopic visualization of the colon using capsule endoscopy, an ingestible device which contains imagers, light sources, a power source and a radio frequency transmitter. Advantages of the PillCam® platform include the elimination of the need for sedation, the minimally invasive, painless nature of the exam, and the ability to pursue normal daily activities immediately following the procedure . Furthermore, compared to standard colonoscopy, the PillCam® platform may be more readily accepted by patients and thereby improving compliance with colorectal cancer screening recommendations.

The PillCam® SB capsule (formerly M2A® Capsule) that was cleared by the FDA in August 2001 for small bowel evaluation has been ingested to date by more than 700,000 people worldwide and is well accepted by patients and physicians as well as the major gastrointestinal professional organizations. However, adequate visualization of the colon cannot be achieved with the standard PillCam®SB capsule because of the anatomical and physiological properties of the colon which are significantly different than the small bowel. Moreover, other issues that limit the evaluation of the colonic mucosa by the standard PillCam® SB procedure include an unsatisfactory level of colon cleanliness and slow progression of the PillCam® SB capsule through the colon during the desired examination time. Therefore, the development and introduction of a specially designed, customized colon capsule combined with a specifically designed capsule colonoscopy procedure allows for more efficient evaluation of the colonic mucosa. This is expected to improve the capability of the PillCam® platform to detect colonic pathologies and to serve as a diagnostic and screening tool for colonic disease. Further details of the PillCam™ Colon Capsule Endoscope (PCCE) can be found in the device description section.

This is a pilot study that is designed to develop the optimal PCCE procedure by measuring the levels of cleanliness and capsule excretion rates. Furthermore, capsule endoscopy and colonoscopy procedures will be compared in regards to the detection of polyps and lesions in the colon.

Eligibility Criteria

Inclusion Criteria

• Subjects over ≥ 50 years of age scheduled for colorectal cancer screening
• Subjects over ≥ 50 years of age with one or more of the following clinical symptoms: rectal bleeding, hematochezia, melena, positive FOBT, recent change of bowel habits, or diarrhea/constipation of recent onset.
• Subject ≥ 18 years of age with one of the following:

• Positive findings (≥ 10 mm polyps) in the colon on a GI radiographic study (BE, CT scan, etc) OR
• Personal history of colorectal cancer (CRC) or adenomatous polyps and ≥5 years since last colonoscopy

Exclusion Criteria

• Subject has dysphagia or any swallowing disorder
• Subject has congestive heart failure
• Patient has significant renal insufficiency, heart disease or any other condition that the investigator would expect to increase the risk of complications from magnesium citrate, such as dehydration or electrolyte imbalance
• Subject has had prior abdominal surgery of the gastrointestinal tract other than uncomplicated procedures that would be unlikely to lead to bowel obstruction based on the clinical judgment of the investigator
• Subject has a cardiac pacemaker or other implanted electro medical device.
• Subject has any allergy or other known contraindication to the medications used in the study
• Subject is expected to undergo MRI examination within 7 days after ingestion of the capsule.
• Subject with any condition believed to have an increased risk for capsule retention such as Crohn's disease, intestinal tumors, radiation enteritis, or NSAID enteropathy,
• Subject with gastrointestinal motility disorders
• Subject has known delayed gastric emptying
• Subject has any condition, which precludes compliance with study and/or device instructions.
• Women who are either pregnant or nursing at the time of screening, or are of child-bearing potential and do not practice medically acceptable methods of contraception such as: surgical sterilization, approved hormonal contraceptives (i.e. birth control pills, Depo-Provera), barrier methods (i.e. condom or diaphragm) used with a spermicide and an intrauterine device (IUD)
• Subject suffers from life threatening conditions
• Subject currently participating in another clinical study

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 75 Years
