Experience with Small Intestino-Videoendoscopy Using Model XSIF-200 (Olympus)

Small intestino-Videoendoscopy was performed in 5 patients using a small intestino-Videoendoscope (model XSIF-200) first developed by Olympus Optical Co Ltd, Tokyo. The clinical assessment of this scope are : (1)Scope function ; An effective length of the scope is 2,000mm and the channel for insertion of forceps used for biopsy and polypectomy is installed in its flexible part. The distaltip at the flexible part has the up/down and left/right angulation system. (2)Technique ; It can be carried out with the same manner as conventional intestinoscopy. (3)Observation ; The excellent image is provided on a TV monitor, permitting smooth cooperation with examiners for biopsy or polypectpmy. (4)Recordability ; Frozen images are available directly to color print photographing without monitoring and to 16mm still photographing through monitoring. Dynamic images can be used for VTR recording. (5)Safety and durability ; Both are excellent compared with conventional intestino-scope. Conclusion : This small intestino-videoendoscope was found to be superior to the conventional fiberscopes for ordinary observations and endoscopic therapy of small intestinal diseases.
