Evaluation of percutaneous cholangiography and percutaneous biliary drainage in obstructive jaundice

104 patients with obstructive jaundice were referred for percutaneous transhepatic cholangiography (PTC) and percutaneous transhepatic biliary drainage (PTBD). The effects of PTBD on postoperative morbidity and mortality were evaluated as well as the occurrence of complications. The results were compared to a group of 33 patients with malignant bile duct obstruction operated without preoperative bile drainage. There was no significant difference in the rate of postoperative complications and mortality between these two groups.
