[Endoscopic therapy of cholangiolithiasis by percutaneous approach. Percutaneous gallstone therapy].
METHODS
In a retrospective study, the results of percutaneous transhepatic therapy of bile duct stones under cholangioscopic control (PTCS) were evaluated in 32 patients in which a endoscopic retrograde stone removal was impossible or failed.


RESULTS
Previous gastric surgery was the most common reason for choosing the percutaneous route (22 cases). Five patients had biliodigestive anastomosis, two pyloric obstructions, and in three patients the retrograde stone removal failed. Complete stone removal was obtained after 3 to 11 (median 5) percutaneous procedures in all cases, in 28 patients by electrohydraulic lithotripsy, and in the remaining 5 cases by mechanical extraction alone. There was no complication due to cholangioscopy and lithotripsy themselves. Two cases had major complications which needed laparotomy (4%, one case had capsular bleeding from the liver, another one had catheter perforation of the duodenum). In addition, three cases (7%) had minor complications which required no therapy during the percutaneous fistula procedure. Two elderly multimorbid patients (4%) died during hospitalisation after successful stone removal not related to the performed procedure.


CONCLUSIONS
The percutaneous transhepatic cholangioscopy (PTCS) and lithotripsy are highly effective techniques for endoscopic treatment of bile duct stones. Because of an increased rate of complications during the fistula procedures, both methods should be restricted to cases with difficult anatomic situation and high risk of surgery.
