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 medical system including an endoscope configured to electrically drive an endoscopic operation. The endoscopic operation includes at least one of a forward and backward movement of an insertion section, a bending angle of a bending section of the insertion section, and a rolling rotation of the insertion section, the endoscope being configured to capture an endoscope image. The medical system further includes a processor comprising hardware. The processor is configured to control the endoscopic operation to achieve a second positioning subsequent to a first positioning, the first positioning being where the insertion section is positioned with respect to a papillary portion of a duodenum, the second positioning positions a distal end section of the insertion section with respect to a papillary portion of the duodenum based on the endoscope image.
