PillCam Colon Capsule and CT-colonography in the Evaluation of Patients With Incomplete Conventional Colonoscopy

Summary

Colorectal cancer (CRC) is the second most common cause of cancer-related death in the Western world, with 500000 deaths per year worldwide. Colonoscopy is accepted as a primary CRC screening tool in many countries. As a preventative procedure, its main purpose is to enable the early diagnosis of CRC at a curable stage and to identify and remove pre-malignant adenomas. Cecal intubation is associated with an increased detection rate of advanced neoplasia, as 33-50% of advanced neoplasia is located in the proximal colon. Complete colonic evaluation is therefore a well-recognized measure of colonoscopy quality control. Cecal intubation rates of ≥ 90% of all colonoscopies in routine clinical practice and ≥ 95% in screening colonoscopies are recommended. Unfortunately, the cecal intubation rate in daily clinical practice is often lower than the target of ≥ 90%, with reported percentages varying from 76.9% to 98.4%. This means that after an incomplete colonoscopy, malignant and pre-malignant lesions may be missed if further investigation is not pursued. Several explanatory factors for incomplete colonoscopy have been described. After an incomplete conventional colonoscopy, patients are required to undergo another test to complete the visualization of the colon. Options for incomplete examinations because of anatomic reasons include both radiologic and endoscopic means.

CT Colonography (CTC ) permits to visualise the whole colon, is minimally invasive, does not require sedation and is well accepted by the patient.

The PillCam Colon Capsule Endoscopy (Given® Diagnostic System)offers an alternative approach for endoscopic visualization of the colon in patients with an incomplete conventional colonoscopy. Advantages of the PillCam Colon Capsule Endoscopy (PCCE) include the elimination of the need for sedation, the minimally invasive, painless nature of the exam, no need of X-rays and the ability to pursue normal daily activities immediately following the procedure. This is a study that is designed to evaluate the performance of the PCCE in the evaluation of patients with an incomplete colonoscopy, compared to the CT-colonography. PCCE and CT-colonography procedures will be compared in regards to completeness of the procedure and detection of lesions in the colon that would have been missed by the incomplete conventional colonoscopy.

Interventions

DEVICE

PillCam Colon Capsule Endoscopy (Given® Diagnostic System)

2nd-generation CCE is 11.6x31.5 mm size, slightly bigger than previous capsule. It has 2 images with an angle of view increased to 172° degrees for each image. CCE-2 captures 35 images/sec. when in motion and 4 images/sec. when virtually stationary. Capsule battery life is at least 10 hours. The Recorder is an external receiving/recording and transmitting unit that receives data transmitted by the capsule. The portable Recorder consists of an antenna array which attaches to the body, a receiver and memory for accumulation of data during the exam. Data transmission is done via high capacity digital link. Workstation is a modified standard personal computer for reviewing videos generated from images acquired by the capsule, interpretation, analysis of acquired data and generating reports.
