Colonoscopy is generally agreed to be the best method for detecting and removing pre-cancerous polyps, but some lesions can be missed, especially if they are located behind folds in the lining of the colon or behind flexures (sharp bends) in the colon.
The Third Eye® Retroscope® is a device that can be inserted through the instrument channel of a standard colonoscope to provide an additional, retrograde (or backward) view that reveals areas behind folds and flexures in the colon. Previous studies have shown the device to be effective for detecting additional polyps that could not have been seen with the colonoscope alone.
The purpose of this research is to compare the additional diagnostic yield obtained by using the Third Eye® Retroscope® vs. the diagnostic yield for the standard colonoscope alone in the context of a randomized, controlled study design.
Patients who are scheduled for colonoscopy will be recruited to the study and randomized to one of two groups. Each patient will undergo two "back-to-back" procedures.
Patients in Group A (study group) will undergo a standard colonoscopy followed immediately by a Third Eye colonoscopy. Patients in Group B (control group) will undergo a Third Eye colonoscopy followed immediately by a standard colonoscopy.
Results from the two groups will be analyzed and compared to determine the effectiveness of the Third Eye Retroscope for detecting additional adenomas and other polyps compared with the standard colonoscope alone.

The Third Eye Retroscope is a device that can be used with a colonoscope to improve the ability of a physician to see areas of the colon that may be hidden from the view of the colonoscope...
This is a prospective randomized trial that aimed to compare the short-term clinical outcomes and systemic inflammatory/cytokine responses of endoscopic submucosal dissection versus laparo...
This is a Registry that invites patients undergoing colorectal surgery for colorectal cancer. Epidemiological data is collected. The Registry includes tumor tissue and blood banks for anal...
Correct identification of Lynch syndrome at the time of colorectal cancer presentation is important. We aim to find best ways to screen patients with colorectal cancer in Korea.
The purpose of this study is to produce a user-friendly tool- in the form of a questionnaire - to accurately assess early quality of life in patients after abdominal colorectal surgery fro...
Although the use of endoscopic submucosal dissection (ESD) as a minimally invasive treatment for large superficial colorectal neoplasms is increasing, colorectal ESD remains technically challenging. A...
Flexible sigmoidoscopy (FS) screening reduces colorectal cancer incidence and mortality. Its potential to detect proximal neoplasms depends on colonoscopy referral. We estimated diagnostic performance...
Endoscopic resection of large colorectal lesions is well reported and is the first line of treatment for all noninvasive colorectal neoplasms in many centers, but little is known about the outcomes of...
Colorectal cancer (CRC) incidence and mortality are higher in black vs white populations. The reasons for these disparities are not clear, yet some guidelines recommend screening black persons for CRC...
The subject of colorectal neuroendocrine neoplasms (NENs), subdivided into well-differentiated NENs, termed neuroendocrine tumours (NETs; grade (G) 1 and 2), and poorly-differentiated NENs, termed neu...
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Hereditary nonpolyposis colorectal neoplasms associated with other malignancies, more commonly of ovarian or uterine origin. When also associated with SEBACEOUS GLAND NEOPLASMS, it is called MUIR-TORRE SYNDROME.
A form of LYNCH SYNDROME II associated with cutaneous SEBACEOUS GLAND NEOPLASMS. Muir-Torre syndrome is also associated with other visceral malignant diseases include colorectal, endometrial, urological, and upper gastrointestinal neoplasms.
Clusters of colonic crypts that appear different from the surrounding mucosa when visualized after staining. They are of interest as putative precursors to colorectal adenomas and potential biomarkers for colorectal carcinoma.
