Gianturco expandable metallic biliary stents: results of a European clinical trial

Abstract

Eleven patients with benign strictures (after choledochojejunostomy, n = 10; chronic pancreatitis, n = 1) and 16 with malignant biliary strictures (cancer of the pancreas, n = 7; cholangiocarcinoma, n = 5) were treated with a self-expanding metallic biliary stent. The patients with benign disease had failed treatment with surgical reconstruction and transhepatic balloon dilation. All patients had immediate relief of jaundice and cholangitis. In a follow-up period of 6-21 months, nine of the 11 patients with benign disease had no difficulties with infection, pruritus, or recurrent jaundice. In patients with malignant strictures, the stent produced relief of biliary obstruction unless recurrent tumor invaded the bile ducts. With careful patient selection, this stent appears to be useful in the management of biliary obstruction, particularly in benign disease.
