Filter by:This is an observational registry study collecting data on the clinical performance of the study device (DiLumen™ ) for its intended use. The primary objective is to evaluate functional outcomes of the DiLumen device in humans. The secondary objective is to evaluate safety characteristics of the DiLumen device.
An NBI-based diagnosis requires training and experience. We are developing a system of computerized image recognition, which can detect possible NBI features of polyps, and provide a more objective diagnosis, which allows nonexpert endoscopists to achieve a high diagnostic accuracy.
This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.
Colonoscopy outcome is strictly related to the adenoma detection rate (ADR). An endoscopy withdrawal time >6min has been suggested to increase the ADR since it allows for thorough evaluation of the several hidden areas of the colon. The FUSE, full spectrum endoscopy system, has been demonstrated to reduce the rate of missed lesions due to its wide-angle view. In the present study the authors evaluate the impact of WT on ADR for High Definition Standard Endoscopes with just a single imager to the FUSE endoscope.
Aim of the registry is to evaluate all colon capsule endoscopies performed in Germany. This is to investigate safety, quality assurance and quality control of colon capsule endoscopy.
There have been very limited evidence about the bleeding complication during colon polypectomy for the patients taking warfarin. This study is aimed to analyse the effect of prophylactic hemo-clipping during colon polypectomy for the patients with warfarin consumption. The enrolled subjects are the patients who take warfarin for high thromboembolism risk and should take heparin bridging therapy during colon polypectomy instead of temporary stopping warfarin. The investigators will randomize into two groups; the patient enrolled into group 1 will be performed hemoclipping for all polypectomy lesion irrespective of the presence of immediate bleeding. And the patients enrolled into group 2 will be performed hemoclipping only for the lesion of immediate bleeding during colon polypectomy. The primary endpoint is to compare the rate of delayed bleeding between two groups.
In a RCT in screening colonoscopy subjects, we will determine if chromoendoscopy using a dilute solution of Indigocarmine (IC) delivered by the water method (study method) will improve adenoma detection rate compared with the water method with plain water alone (control method).
In a prospective, randomized, controlled study, two methods (water method vs. air method) of performing colonoscopy will be compared in patients undergoing unsedated colonoscopy for CRC screening. The investigators hypothesize that: 1. Study method increases overall cecal intubation with comparable assessment of current experience and patient willingness to repeat future colonoscopy compared with conventional colonoscopy 2. Study method improves bowel preparation and increases polyp pickup rate
