[A retrospective study on the use of preoperative percutaneous drainage in uncomplicated obstructive jaundice].

This study concerns a retrospective analysis of the use of preoperative percutaneous biliary drainage in the treatment of obstructive jaundice complicated or not by cholangitis. From 1980 to 1987, 87 patients were selected; among these, only those with bilirubin greater than 5 mg% and an overt indication to surgery were included in the study. It was so possible to match two relatively homogeneous populations, e.g. patients submitted to preoperative drainage vs patients not drained. According to our experience, a preoperative percutaneous biliary drainage does not affect postoperative mortality, incidence of immediate postoperative complications and length of hospitalisation. These results are probably linked to a predominant use of the drainage in absence of infectious complications.
