Abstract
Eighty-seven publications in English on endoscopic bile duct stenting for palliation of obstructive jaundice were electronically or manually retrieved. Only eight of these studies were found to represent series of more than 20 patients and to include only a single presentation of data from patients published more than once. These eight studies refer to data on 856 patients, of whom 702 are from four open series, whereas 154 are from four randomized trials comparing endoscopic insertion of endoprosthesis to percutaneous stents or surgical by-pass. Endoscopic insertion was successful in about 90% of the patients. Stent diameters were 7-12 French. Patient survival was not affected as it is governed by the natural history of the underlying malignant disease. Endoscopic endoprosthesis was superior to percutaneous stenting and equal to surgical by-pass, but probably less resource consuming. The most important unsolved problem is the tendency to cholangitis and clogging of endoprostheses. Some suggestions concerning questions to be addressed in a more uniform manner in future publications on this subject are presented.
