Cholelithiasis is one of the most common gastrointestinal disorders. Cholelithiasis is divided into gallbladder stone, common bile duct stone, and intrahepatic stone by site of development. Each type develops either secondarily to other conditions or independently. When asymptomatic common bile duct stones are detected, they are highly likely to become symptomatic. Thus, aggressive treatment is basically recommended regardless of the presence or absence of symptoms. Endoscopic treatment of common bile duct stones is established as the first treatment of choice for common bile duct stones at many facilities worldwide. Endoscopic sphincterotomy (EST) is usually performed in Western countries. However, in Japan, endoscopic papillary balloon dilation (EPBD) as well as EST is performed at many institutions. When the stone diameter exceeds the diameter of the EST- or EPBD-treated papilla, they need to be fragmented and removed through the papilla. Lithotripsy procedures include endoscopic mechanical lithotripsy (EML) and peroral cholangioscopy-guided electrohydraulic shockwave lithotripsy. In recent years, endoscopic papillary large balloon dilation (EPLBD) has come into clinical use.
