Abstract: A diagnostic system, method, and a computer-readable storage medium for determining a severity of a gastric condition, such as gastritis, in a subject are disclosed. The diagnostic system includes a processor that obtains an image of a stomach of the subject collected by an endoscope. The processor can compare the subject image with reference normal and abnormal stomach images. If the subject image is abnormal, the processor can generate a subject abnormality image indicative of the differences between the subject image and the normal image. By comparing the generated subject abnormality image with reference abnormality images representative of different severity levels of gastritis, the processor can diagnose the subject as having a particular severity level of gastritis.

Abstract: A treatment tool for an endoscope, includes a sheath which has a center axis along a longitudinal axis; a pre-curved portion which is disposed at a distal portion of the sheath; a knife wire lumen which has a center axis and is formed along the longitudinal axis; a cutting portion which protrudes from an outer circumference surface positioned at an inward side of the curved shape to outside of the pre-curved portion and extends from a distal end portion toward a proximal end portion of the pre-curved portion; a guide wire accommodation portion which is formed along the longitudinal axis of the sheath; a proximal slit formation portion which is communicated from the guide wire accommodation portion to the outside of the sheath; and a distal slit formation portion which is extended from the proximal end of the pre-curved portion to an intermediate portion of the pre-curved portion.

Abstract: An endoscope system includes a direct-view endoscope configured to capture images, a treatment tool configured to be inserted into the endoscope, and a controller comprising hardware, the controller being configured to control a drive device to drive the endoscope and the treatment tool, to control driving of the endoscope to locate the endoscope inserted into a lumen in the vicinity of a nipple, to control driving of the treatment tool to move the nipple using the treatment tool, to acquire a first captured image of the nipple from the endoscope, and to predict a shape of a biliary duct connected to the nipple in the first captured image based on biliary duct shape information comprising a standard image of the nipple that is associated with a standard shape of the biliary duct.

Abstract: A high-frequency treatment tool for an endoscope includes: a sheath formed of a material having an insulation property; a shaft-shaped member formed of a material having conductivity and inserted to advance and retract in the sheath; and an electrode having a conduit line formed to jet forward a fluid supplied into the sheath, and connected to a distal end section of the shaft-shaped member. The electrode has an outer circumferential surface electrically connected to a contacted tissue to perform treatment, and an inner circumferential surface of the conduit line that faces the fluid when the fluid is supplied. An arithmetic average roughness of the outer circumferential surface is larger than an arithmetic average roughness of the inner circumferential surface, and the arithmetic average roughness of the inner circumferential surface is 0.1 μm or less.
