| [ Summary ] | Whereas there are a number of choices in the treatment of bile duct stones, transpapillary endoscopic treatment is becoming the major one, because of its lower degree of invasiveness. These treatments are endoscopic sphincterotomy (EST) or endoscopic papillary balloon dilation (EPBD), and the two have respective advantages. The factor which has made it possible to perform these treatments in a stable and safe manner is the introduction of the guidewire. However, the length of the guidewire necessary for changing treatment devices through the endoscopic channel is 400 to 450cm. The operation has been presenting problems, such as requiring more than one operational assistant, taking a long time to change devices and a tendency to become unsanitary. To solve these problems, the Rapid Exchange Biliary System has been developed with the concept of "performing rapid changes in the operational devices with a short guidewire". Sphincterotome and special balloons for EPBD have also been developed along this line, and soon endoscopic treatment for bile duct stones may be performed, using a serial procedure. | |
