This clinical trial tests a multilevel intervention at the clinic, provider and patient levels, to improve colonoscopy surveillance in patients with high risk colon polyps. Colorectal cancer (CRC) is a common and deadly disease that is largely preventable through the detection and removal of colorectal polyps. One million Americans are diagnosed with high risk polyps of the colon or rectum annually and are at increased risk for CRC; however, uptake of recommended repeat colonoscopy in 3 years to reduce CRC risk is low in this group. This multilevel intervention may work to improve timely colonoscopy screening for patients with high risk colon polyps.
This is a multi-site comparative effectiveness randomized controlled trial (RCT) comparing annual fecal immunochemical testing (FIT) and colonoscopy for post-polypectomy surveillance among adults aged 65-82 with a history of colorectal polyps who are due for surveillance colonoscopy.
The main objective of the study is to determine the ability of the C-Scan system to identify subjects who are at elevated risk for colon polyps. This will be evaluated by comparing the C-Scan data to colonoscopy data. The C-Scan procedure is therefore performed before the colonoscopy procedure, in order to compare these tests and evaluate the C-Scan system's effectiveness. During the C-scan procedure, Subjects will be asked to come for an appointment in a clinic, during this appointment, the C-Scan Track will be placed on the participant's back. The participant will then be asked to swallow the C-Scan capsule whereafter they are free to continue their routine. Participants will start intake of fiber pills 5 days, and contrast agent 48 hours prior to C-Scan capsule ingestion and will continue intake up to the capsule's natural excretion. A standard colonoscopy procedure will be performed within 60 days following C-Scan Cap ingestion.
Complete polypectomy is one of the major factors for effectiveness of colonoscopy to prevent colon cancer. Given the prevalence of the 4-6 mm polyp, and the concern about interval cancers at polypectomy sites, there is a clear and significant need to determine which technique(s) are most appropriate for clinical practice. This study was to compare the three commonly used polypectomy techniques in terms of efficacy and efficiency.
This study will evaluate the safety and effectiveness of the CapsoCam Colon (CV-3) endoscope system for the detection of colonic polyps.
EndoVigilant software device augments existing colonoscopy procedure video in real-time by highlighting colon polyps and mucosal abnormalities. It is intended to assist gastroenterologists in detection of adenomas and serrated polyps. The device is an adjunctive tool and is not intended to replace physicians' decision making related to detection, diagnosis or treatment. This study with an adaptive design measures the clinical benefit (increase in detection of adenomatous and serrated polyps) and increased risk (increased extraction of non-adenomas) during standard colonoscopy procedures when EndoVigilant software device is used.
Patients who have provided informed consented and are scheduled to undergo endoscopic mucosal resection (EMR) of lesions 15mm and larger will be randomized to STSC (80 W, Effect 5) vs APC (preferred settings) vs No Treatment of the perimeter of the EMR site.
The purpose of this study to evaluate and examine whether use of Hybrid Argon Plasma Coagulation (APC) as an adjunct to endoscopic mucosal resection (EMR) will reduce the risk of residual or recurrent neoplasia at 6 months. Hybrid APC is an existing FDA approved device used to assist with ablation of abnormal tissue anywhere in the GI tract.
A prospective outcomes study in patients referred for endoscopic mucosal resection of complex colon polyps.
The primary objective of this multicenter, prospective, randomized study is to assess the diagnostic yield of Colon Capsule Endoscopy (CCE) versus Computed Tomographic Colonography (CTC) in a screening population.
