description

We report on a 67-year-old female patient who presented in July 2005 with sudden onset of pain in the right upper abdomen. The patient had undergone cholecystectomy in 1987. Because of recurrrent complaints in the right upper abdomen, a pigtail stent was placed into the common hepatic duct in 2001. When the patients presented now, the laboratory tests including liver enzymes were within normal ranges. Endoscopic retrograde cholangiogi aphy, however, revealed a remaining 10-French, impacted double pigtail endoprothesis that was obstructed by sludge as well as multiple giant bile duct stones of 20 to 30 mm in size. The giant stones could be finally removed by the combined use of ESWL and endoscopic techniques. This case demonstrates that impacted stents may favour the development of giant bile duct stones that may result in clinical symptoms only after prolonged periods of time.
