Percutaneous biliary drainage, as palliation for malignant biliary obstruction, is subject to complications, particularly blockage of the drainage tube. Blockage may occur because of duodenal tumour involvement. In nine patients with blockage of the biliary-duodenal drainage tube, conversion to biliary-jejunal drainage allowed continued internal drainage of bile.
经皮胆道引流作为恶性胆道梗阻的姑息治疗方法，容易出现并发症，尤其是引流管堵塞。堵塞可能是由于十二指肠肿瘤侵犯所致。在9例胆十二指肠引流管堵塞的患者中，改为胆肠引流可使胆汁持续进行内引流。
