Metal clip as a nidus for formation of common bile duct stone following laparascopic cholecystectomy.

A 83-year-old woman came to our hospital with fever up to 38.5 degrees C, abdominal pain and jaundice. She had undergone a cholecystectomy for symptomatic gallstones in 1992. The endoscopic retrograde cholangiography showed a dilated common bile duct with a free floating surgical clip with stone formation around this foreign body. After endoscopic sphincterotomy the extraction of the foreign body was successful. We found a two cm cholesterol stone the nidus of which was built by a Filshie-clip. The post endoscopic course was uneventful.
