[Clinical study on the endoscopical lithotomy in cholecystolithiasis]

Endoscopical lithotomy was carried out in 14 patients with cholecystolithiasis. 6 patients were men and 8 were women (age 40-78). 4 of them underwent endoscopical lithotomy because of their inoperability. The other patients refused surgical operation and wished the procedure. Percutaneous Transhepatic Cholecystic drainage (PTCCD) was performed at the right intercostal space under ultrasonic guide and was dilated to 16 Fr in diameter. After 1-2 weeks, lithotomy by using Percutaneous Transhepatic Cholecystoscopy (PTCCS) started. Nd-YAG laser and/or Electrohydraulic lithotripter were used to fragment stones. Lithotomy was successfully finished without serious complications in all cases. In conclusions, the therapeutic advantage of PTCCS may be expected for cholecystolithiasis.
