title: [Percutaneous treatment of common bile duct lithiasis].
abstract: OBJECTIVE
  Biliary lithiasis in the main bile duct (particularly retained stones) may be treated percutaneously obviating reoperation or endoscopic sphincterotomy. The aim of this study was to determine risks and pitfalls of this approach.
  
  
  METHODS
  Forty-two cases of biliary stones treated percutaneously between 1980 and 1998 were reported. Among them, 28 patients had already a biliary drainage and in 14, a drain was placed into the bile duct by transhepatic way or by punction of the intestinal loop of a bilio-jejunal anastomosis. The means to clear the bile ducts included percutaneous endoscopy and contact lithotripsy. Thirty patients had residual lithiasis (after a surgical intervention), 11 a new lithiasis above a bile duct stenosis and in 1 a bile duct lithiasis with a gallbladder lithiasis.
  
  
  RESULTS
  Morbidity included four complications (9.5%--one severe) and no mortality. After 2.3 +/- 1 courses, desobstruction was complete in 33 cases (78.5%) and partial in one case (2.5%) allowing to optimize the patient for endoscopic sphincterotomy. Desobstruction failed in eight cases (19%), six patients were successfully treated by surgery and 2 by endoscopic sphincterotomy.
  
  
  CONCLUSIONS
  Percutaneous desobstruction of the bile ducts may be proposed as a priority in patients with a biliary drain in place and when endoscopic sphincterotomy is impossible or contraindicated. These manoeuvres have a definitive place in hepato-biliary surgery.
