Two Cases of Percutaneous Transhepatic Choledochoscopy Treatment of Intrahepatic Duct Stones that Occurred after Living Donor Liver Transplantation / 대한소화기내시경학회지

Percutaneous transhepatic cholangioscopy (PTCS) is the primary treatment option for general cases of intrahepatic duct stones. However, there are no reports on the use of PTCS for intrahepatic duct stones in patients who had undergone living donor liver transplantation (LDLT). We experienced two cases of successful intrahepatic stone removal by the use of PTCS in LDLT patients. With these cases, we have confirmed that PTCS management can be safely performed not only for a general bile duct stone, but also for a bile duct stone that develops in a patient that had previously undergone liver transplantation.

Hepatocellular Carcinoma with Obstructive Jaundice Confirmed by Percutaneous Transhepatic Cholangioscopy (PTCS) and Peroral Cholangioscopy (POCS) / 대한소화기내시경학회지

Jaundice associated with hepatocellular carcinoma usually occurs in the later stages due to the advanced underlying liver cirrhosis or tumor infiltration of the liver parenchyme. In the rare cases, obstructive jaundice presents as the ininitial manifestation of hepatocellular carcinoma. The possible mechanisms of bile duct obstruction associated with hepatocellular carcinoma include extrinsic compression of bile duct by extensive tumor infiltration of the liver or enlarged lymph node, direct tumor invasion of the biliary duct system, and bile duct obstruction by tumor thrombus, necrotic debris, or blood clots. We experienced three cases with hepatocellular carcinoma in whom obstructive jaundice were caused by intraductal involvement of the tumor, which were confirmed by percutaneous transhepatic cholangioscopy(PTCS) and peroral cholangioscopy(POCS). PTCS and POCS finding showed multiple, irreguarly shaped, yellowish soft tissue(chicken fat) and blood clots and, round protruded mass in the ble duct. Biopsy specimens revealed pathologically hepatocelluar carcinoma.
