Abstract

Recent advance in therapeutic gastrointestinal endoscopy and cryosurgical techniques have caused an interest in creating a cryo-instrument for endoscopic use. The development of a prototype instrument for use in both upper gastrointestinal endoscopy and colonoscopy is described. This instrument is based on the expansion of high pressure carbon dioxide in a series of flexible tubes designed to fit through a 2.6 mm endoscopic accessory channel. This self-enclosed system has been used clinically for cryo-extraction of cauterized colonic polyps. Its potential use for treatment of gastrointestinal malignancies is discussed.
