Non-surgical palliative treatment of patients with malignant biliary obstruction--the place of endoscopic and percutaneous drainage.
Non-surgical methods to treat patients with inoperable malignant biliary obstruction are endoscopic retrograde biliary drainage and ultrasound guided percutaneous transhepatic biliary drainage. During a 2 year evaluation a total of 144 patients were admitted with malignant biliary obstruction: 93 with a mid- or distal common bile duct stenosis; 51 patients with a perihilar stenosis. Endoscopic biliary drainage was performed in 123 patients and ultrasound guided percutaneous biliary drainage in 57 patients. An effect on jaundice was seen in more patients after percutaneous biliary drainage (91%) than with endoscopic biliary drainage (70%). However with the percutaneous method only 63% of patients were drained internally. The site of the stenosis seemed to be an important factor. In patients with perihilar obstruction early complications after endoscopic biliary drainage occurred in 41% of drained patients compared with 3% procedure-related and 28% catheter-related complications with ultrasound guided drainage. A major complication of the endoscopic method in perihilar disease was cholangitis due to inadequate drainage.
