COLONOSCOPY USING DOUBLE BALLOON ENDOSCOPY

Abstract

With the increase of colon cancer, colonoscopy is getting demanded more. Insertion method of double balloon colonoscopy is explained in this technical review. Double balloon colonoscopy is an easy, safe and reliable method. In this method, the inserting force applied to the endoscope shaft is effectively transmitted to the endoscope tip while preventing the stretching of the colon with a balloon-attached overtube. Because the shape of the colon is arranged to be suitable for insertion by gripping the colon with the balloons, the endoscope can be inserted reliably with minimal pain. Double balloon colonoscopy enables total colonoscopy in difficult cases with regular colonoscopy. It is also useful for colonoscopic treatment because it can provide good control of endoscope tip. For acquiring the skill of insertion, it is important to understand the principle of the method and try to insert the endoscope as gentle as possible.
