Randomized Controlled Trial Clinical Trial
Pre-operative percutaneous transhepatic biliary drainage: the results of a controlled trial.
The operative mortality for biliary tract obstruction due to malignancy is high. In 1981 a controlled clinical trial of pre-operative percutaneous drainage was started at the Royal Postgraduate Medical School. At the time of percutaneous transhepatic cholangiography patients were randomized either to laparotomy or to pre-operative percutaneous transhepatic biliary drainage ( PTBD ) followed by laparotomy. ⋯ Five patients required early surgery for complications of PTBD and two died within 30 days of surgery. The mortality for laparotomy was 19 per cent (6/31) compared with 32 per cent (11/34) for drainage plus laparotomy. This trial highlights the hazards of PTBD in high risk patients and has failed to demonstrate a reduction in mortality with the use of pre-operative PTBD .
