In patients with obstruction of the common bile duct caused by primary pancreaticoblliary tumors, Wallstents have been shown to remain patent for a median duration of 273 days (range: 14-363). However, in one study that included both patients with primary pancreaticobillary malignancies and patients with metastatic malignant disease, the reported median Wallstent patency was found to be significantly shorter. We have studied the patency of Wall-stents in patients with metastatic billary obstruction.
