Abstract
We have been engaged in making a proper fiber-intestinoscope. The point of our aim is to carry out the intestinoscopy with simple and easy preparation an in gastroscopy or duodenoscopy . So, we adopted the push method, introducing the f iberscope actively from the mouth. Recently we have succeeded in making a fiber-jejunoscope, which could be applied for clinical use with satisfactory results.1) Our fiber-jejunoscope could be inserted distal of the duodenojunal flexure in 25 cases out of 33 and could observe the jejunal mucosa well, but observance of the small lesions and villi was not very satisfactory. It was easy to do aiming biopsy from a large lesion but was difficult from a small target.2) We established the technique of passing the duodenojejunal flexure by using a rigid outer sheath and proved its advantage.3) We consider that the greatest roll of fiber-intestinoscopy is to diagnose enteritis under direct vision with help of biopsy and to make an endoscopic approach to the mechanism of digestion and absorption of the small intestine. For this purpose we would like to improve our technique and instruments further.
