[The current value of percutaneous transhepatic biliary drainage].
Percutaneous transhepatic biliary drainage (PTBD) is a well established method in the treatment of obstructive jaundice. Major indications are malignant diseases. PTBD may be necessary preoperatively in cases with severe jaundice or cholangitis or as part of palliative treatment concepts. In the past, it has been proposed that a period of preoperative PTBD may improve the morbidity rates of surgery. Various studies could not prove this theory. The significance of preoperative PTBD has changed, as observed during a 15 years period in our own institution, the indications for preoperative PTBD have decreased by half. At present, the majority of treatments with PTBD are palliative (almost 70 % of all procedures). The diagnostic opportunities of the transhepatic approach (intraductal sonography, cholangioscopy, biopsy) are exploited only in few selected cases. Since the radiological approach ist considered to be invasive and related to serious complications most patients are being referred to endoscopic drainage first. Radiologists are consulted in complicated cases of jaundice and when endoscopic approaches have failed. The retrospective evaluation of more than 1000 procedures over a period of 16 years demonstrates good results with a low rate of serious complications. During the two observed periods of nine and seven years, respectively, there occurred complications like sepsis in 1.9 %/0.5 %, peritonitis in 0.5 %/0.7 %, severe bleeding in 0.5 %/1.5 %, procedure-related death in 0.8 %/0.7 %. The overall rate of serious complications was 5 %/3.4 %. These results are comparable to those of the endoscopic approach with a complication rate of 3.6-14 % and a mortality rate of 0.5 %.
