86-year-old woman who underwent cholecystectomy and ERCP for choledocholithiasis performing
sphincterotomy and stone extraction. She presented to our center for epigastric pain
without infection signs, finding common bile duct (CBD) dilatation and choledocholithiasis
in MR-cholangiopancreatography. ERCP was performed, finding dilatation of common bile
duct (15-17mm) and a 12-15mm stone with radiopaque content like surgical clips, being
unable to define if it was in CBD or cystic duct. After failed attempt of standard
stone extraction, an endoscopic papillary large-balloon dilatation was performed and
stone removed with balloon catheter. Stone was recovered and analysed, confirming
the presence of a surgical clip inside.
