Biliary stones can be easy or difficult to remove, depending on their dimensions. Understanding bile ducts anatomy, choosing the appropriate devices/extraction technique, developing confidence with biliary lithotripsy, choosing the appropriate size of the sphincterotomy, performing large balloon biliary dilation in appropriate cases and management of failed stones extraction are the basic key issues in the management of biliary stones. Here, we present the case of a 96-year-old female patient who had an episode of cholangitis one week ago and ERCP was performed with a biliary precut to access the bile duct. Since the biliary stones were large, a biliary plastic stent was placed and after unintentional pancreatic duct cannulation, a pancreatic stent was also placed to prevent pancreatitis. ERCP was repeated. The biliary stent was removed since the stones were approximately 12mm in diameter. A biliary balloon dilation was carried out to facilitate the removal. At the end, the pancreatic stent was also removed.
