Filter by:The goal of this clinical trial is to evaluate the diagnostic yield of CADe in a consecutive population undergoing colonoscopy. The main question it aims to answer is the Adenoma Detection Rate (ADR). Participants undergoing colonoscopy for follow-up in a screening setting will be randomized in a 1:1 ratio to either receive Computer-Aided Detection (CADe) colonoscopy or a conventional colonoscopy (CC). GI Genius is the AI software that will be used in the present trial and is intended to be used as an adjunct to colonic endoscopy procedures to help endoscopists to detect in real time mucosal lesions (such as polyps and adenomas, including those with flat (non-polypoid) morphology) during standard screening and surveillance endoscopic mucosal evaluations. It is not intended to replace histopathological sampling as a means of diagnosis.Researchers will compare the CADe group and the CC-group to see if CAD-e can increase the ADR significantly.
The goal of this trial is to determine whether use of a Computer Assisted Detection (CADe) programme leads to an increase in ADR for either units or individual colonoscopists, independent of setting or expertise
Colonoscopy is considered the gold standard for diagnosis of colonic polyps. However, it was reported that colonoscopy could still miss colonic polyps. Many attempts have been made to improve the detection rate of colonoscopy. Artificial intelligence (AI) is a promising new technique to improve detection rate of colonic adenoma. However, it remains uncertain whether whether the combined use of Endocuff and AI assisted examination could help to further improve the adenoma detection rate. This is a prospective randomized trial comparing the use of endocuff with AI, AI alone or conventional colonoscopy examination on adenoma detection rate.
Colorectal carcinoma (CRC) is the third most common cancer in male and female worldwide. In India, it is the fourth most common cause of cancer in males and third most common cancer in female. Age, smoking, colonic adenomatous polyp, family history are traditional risk factor for CRC. The vast majority of CRC results from malignant transformation from adenoma, which is called as adenoma carcinoma sequence. These adenomatous polyps grows slowly over many years and malignant transformation eventually occurs over 10 years. So, the early detection and removal of polyp at early stage should benefit in preventing CRC.
Endoscopic full-thickness resection (EFTR) in the colon using an over-the-scope clip (OTSC) as a closure mechanism is a recent technique that allows the endoscopic resection of colonic lesions that are poor candidates for conventional endoscopic resection techniques. The aim is to study the safety and efficacy of EFTR in colon.
Screening colonoscopy for colorectal cancer is essential to diagnose and remove adenomas, precancerous stages of colorectal cancer. Unfortunately approximately 25 % of all adenomas are missed during the examination. Recently a new colonoscopy accessory, the Endorings-2 (EndoAid Ltd., Casearea, Israel), has been designed to improved the detection of adenomas during colonoscopy (adenoma detection rate). Endorings-2 is a silicone-rubber device that is fitted on the colonoscope and is equipped with circular flexible silicon rings mechanically stretching the colonic folds during withdrawal. This study aims to evaluate the efficacy of Endorings-2 to improve the adenoma detection rate in a prospective, blinded clinical trial. 292 patients with an indication for a screening colonoscopy shall be included (1:1 randomization in standard colonoscopy versus Endorings-2-assisted colonoscopy).
Colonoscopy continues to be the gold standard in detecting precancerous lesions in the colon. It relies on adequate visualization of the bowel wall to see and remove such lesions. Visualization is improved with luminal distention, and a multitude of studies have been done to determine ways to increase this luminal distention. The investigators theorize that positioning in the Right Lateral Decubitus rather than the Left Lateral Decubitus may be a cost free method to increase luminal distention and, hence, improve visualization in colonoscopy. In the Right Lateral Decubitus position, the sigmoid colon and cecum - both parts of the bowel that are not fixed - air used during colonoscopy will rise in a dependent fashion, increasing luminal distention. In the left lateral decubitus position, the bowel collapses, creating an often difficult area to maneuver and visualize. The investigators would like to compare both positions to determine if it affects outcomes in colonoscopy. In particular, cecal intubation rates and adenoma detection rates.
