Technical and clinical data concerning 731 controlled patients submitted to nonsurgical percutaneous biliary drainage (PBD) for preoperative or palliative purposes were collected from eight institutions. Using a computerized analysis program, general and special statistics were obtained, with special attention given to 536 neoplastic cases. Technical success, type, level and nature of the lesions, purpose of drainage, surgery performed, complications, and other clinical and technical information were considered and compared with the clinical results. Statistically significant data were obtained comparing, respectively, bilirubin levels with duration of drainage, survival with type of treatment (PBD alone or followed by radical or palliative surgery), operative with post PBD mortality, survival with type of PBD (external catheter, internal catheter, and endoprosthesis), and complications with type of PBD used.
