[Biliary pseudocyst as a rare complication of choledocholithiasis].

Biliary pseudocysts, so-called biliomas are reported to be an extreme rarity and mostly arising posttraumatic. We report on a case of symptomatic choledocholithiasis 7 years after cholecystectomy. The course was complicated by formation of a biliary pseudocyst. The 71-year-old, septic patient could not be operated because of pulmonal and cardiac high risks. He could be treated successfully by conservative procedure via endoscopic papillotomy, stone extraction and percutaneous, sonographic controlled drainage of the biliary pseudocyst.
