Filter by:SIC 8000 is indicated for use in gastrointestinal endoscopic procedures for submucosal lift of polyps, adenomas, early-stage cancers or other gastrointestinal mucosal lesions, prior to excision with a snare.
The purpose of this study is to compare the performance of a new prototype colonoscope with a standard colonoscope used world-wide today. The prototype colonoscope is more flaccid with a smaller diameter than the standard colonoscope. The hypothesis to be tested is that the prototype will improve negotiation of sharp bends and inflict less discomfort or pain to the patient. Both colonoscopes are manufactured by the same company.
Does a new colonoscopic viewing technique called narrow band imaging (NBI) help doctors detect more patients with at least one pre-cancerous polyp (adenoma) than conventional colonoscopy using white light alone? May 2007 protocol minor amendment: additional viewing by endoscopists outside St Mark's ro allow assessment of inter- and intra-observer variability.
This is a randomized controlled trial of aspirin and/or folate supplementation for the prevention of the recurrence of neoplastic polyps (adenomas) of the large bowel.
Extensive experimental and observational data suggest that intake of calcium and of vitamin D exert protective effects on colorectal neoplasia. Building on their previous work, the investigators will investigate the chemopreventive effect of vitamin D in the large bowel, to study whether calcium with vitamin D is more effective than calcium alone, and to confirm their positive finding regarding calcium. The goal of this study is the development of chemopreventive combinations that will reduce risk of colorectal neoplasia sufficiently to permit the lengthening of surveillance intervals in most patients and to clarify important issues regarding the mechanisms of colorectal carcinogenesis and chemoprevention.
