Abstract
When we use an ultrasonic micro-probe for lesions in the upper gastro intestinal tract, there may be difficultiy to fill de-aerated water. We apply an optical laser balloon(M&MCo. Ltd)to deal with the difficulties. We attach the optical laser balloon on the tip ofan endoscope and fill de-aerated water in the optical laser balloon via the forceps channelof the endascope. Ta perform endosonagraphy, eve introduced an ultrasonic mitre-probevia the forceps channel of the endoscope. By means of this device, we do not have difficultyto fill water at any places in the upper gastro intestinal tract. we could ebtain theendosbnogram of the lesion with ease, because we could keep an optimal angle and distancebetween the ultrasonic micro-probe and the lesion. Furthermore, patients did not complainapain due to reflex of the de-aerated water during examination. This device will makean innovation in the endosonography by u.tilizing the ultrasonoc micro-probe.
