We devised an esophagofiberscope with a magnifying apparatus (FES-MB, by Machida Co. Ltd.), for the purpose of getting better visions in differentiation on esophageal lesions. This apparatus, attached to the ordinary esophag-ofiberscope, gives the maximum magnification up to 1.7 by 15 times by operating the handle. This was designed to have a hole for the markerof the sport in the magnifiedGastroenterological Endoscopy area. It gavean great improvement on the result of shooting biopsy. In this way this apparatus can be used for the routine esophagoscopy. Various esophageal lesions were shown in the recordings with ordinary esophagof iberscope and with the magnifying apparatus. This apparatus was useful for observing esop-hageal mucosa, especially on reddening, erosion, small vessels around ulceration and magnified mucosal surface after dying mucosa. Detailed observations with magnifica-tion on elevated lesions was also very useful for getting better differential diagnosis. Cancerous surface was shown with characteristic mucosal form. This detailed observation with magnifying endoscope willl become more common in all on the digestive system, and may, in the future, change the course of development of the endoscopy itself.
