Ultrasonically guided percutaneous transhepatic cholangiography (UG-PTC), bile drainage (UG-PTBD) and gallbladder drainage procedure (UG-PTGBD), developed by us, were performed in 47, 183 and 36 patients, respectively. In 47 patients UG-PTC was successfully performed 51 times without complications. By UG-PTBD 220 intubations were carried out successfully and four attempts failed (1.8%). The main complication was that the catheter slipped out from the bile duct. It was experienced 27 times (12.3%) in 23 patients (12.4%) from two to 47 days after intubation. UG-PTGBD was successfully performed 36 times. Bleeding from the catheter was experienced in four patients. However, other complications such as cholascos were not experienced. Due to the development of ultrasonic diagnosis and the UG-PTBD procedure, the indications for percutaneous transhepatic cholangiography (PTC) are now limited. For differentiation of jaundice, ultrasonic examination takes over from PTC. For preparation of PTBD, thin needle cholangiography is no longer necessary because UG-PTBD is a single-step procedure without the need for cholangiography. Therefore, the indication for PTC is limited to patients with partial dilatation of intrahepatic bile ducts without jaundice, for example when only the left hepatic duct is dilated due to hepatolithiasis.
