Endoscopic removal of asymptomatic common bile duct stones (CBDS) is generally recommended. Although many reports have described the risk of complications in endoscopic retrograde cholangiopancreatography (ERCP), no studies have addressed this problem in the context of asymptomatic CBDS.

Among the problems in the application of the high-water-content fluid, erosion induced by a cavitating jet is an important and complex one. A high-velocity jet accompanying cavitation can be observed in hydraulic valves and hydraulic pumps. This paper treats erosion induced by a cavitating jet flowing out from a triangular notch. A pair of test pieces is used in each experiment. The first test piece has a triangular notch from which the fluid flows out, forming a jet. The jet impinges to the second ...
