[Comparative assessment of percutaneous transhepatic cholangiodrainage under roentgenoscopy and ultrasound guidance].

In 1990-2000, percutaneous transhepatic cholangiodrainage was performed in 89 patients with obstructive jaundice of tumoral etiology: Groups A (n = 21) under roentgenoscopic guidance and Group B (n = 68) under ultrasound guidance (USG). The efficiency and safety of puncture of the biliary tract were comparatively evaluated in these groups. The technical success of the procedure was achieved in 81.0% of Group A patients and in 98.5% of Group B ones. USG decreased radiation load on the patient and medical staff by three times and the number of needle passes by two times. External-and-internal cholangiodrainages under USG and roentgenoscopy were performed in 55.2 and 23.8%, respectively. The incidence of complications and mortality were 5.9 and 1.5% in Group B and versus 17.6% and 4.8% in Group A. It is concluded that transhepatic cholangiodrainage under USG has some advantage over puncture of the biliary tract under roentgenoscopy.
