Uncovered Self-expandable Metal Stent Versus Double Layer Plastic Stent for Malignant Hilar Stricture

2014-08-27 03:13:35 | BioPortfolio


The overall median survival of nonresectable malignant hilar obstruction in most series has been less than 6 months. Most patients with malignant hilar obstruction present with advanced disease, making palliative endoscopic drainage the principal therapeutic option. However, the optimal endoscopic management strategy is contentious. Almost all of the published data comparing plastic and metallic stents relate to distal tumors (those of the pancreas, common bile duct and ampulla). Stent patency, complication rates, and cost-effectiveness have favored metallic stents when compared with plastic stents in patients with distal malignant obstruction expected to live at least 3 to 6 months.

There are few comparative study as to whether self-expanding metallic or plastic stent, especially DLS (double layer plastic stent) are preferable in the technical success, stent patency, and cost-effectiveness for palliating malignant hilar obstruction.

The study was designed to compare the the technical success, stent patency, and cost-effectiveness of self-expandable metal stent and DLS in patients with malignant hilar obstruction.

Medical and Biotech [MESH] Definitions

A mutation named with the blend of insertion and deletion. It refers to a length difference between two ALLELES where it is unknowable if the difference was originally caused by a SEQUENCE INSERTION or by a SEQUENCE DELETION. If the number of nucleotides in the insertion/deletion is not divisible by three, and it occurs in a protein coding region, it is also a FRAMESHIFT MUTATION.

A congenital anatomic malformation of a bile duct, including cystic dilatation of the extrahepatic bile duct or the large intrahepatic bile duct. Classification is based on the site and type of dilatation. Type I is most common.

The largest bile duct. It is formed by the junction of the CYSTIC DUCT and the COMMON HEPATIC DUCT.

The duct that is connected to the GALLBLADDER and allows the emptying of bile into the COMMON BILE DUCT.

Passages external to the liver for the conveyance of bile. These include the COMMON BILE DUCT and the common hepatic duct (HEPATIC DUCT, COMMON).
