Summary of "Endobiliary radiofrequency ablation combined with bilateral metal stent placement for malignant hilar biliary obstruction."

 The effectiveness of endobiliary radiofrequency ablation (RFA) is still uncertain, especially in patients with malignant hilar biliary obstruction (MHBO). We examined the efficacy of endobiliary RFA followed by bilateral self-expandable metal stent (SEMS) placement for unresectable MHBO.

Medical and Biotech [MESH] Definitions

The application, via IMPLANTED ELECTRODES, of short bursts of electrical energy in the radiofrequency range, interspersed with pauses in delivery of the current long enough to dissipate the generated heat and avoid heat-induced tissue necrosis.

A liquid resinous varnish solubilized in a volatile solvent which may be combined with a pigment. It forms a hard, glossy, and protective coating when applied to wood or metal.

Removal of tissue by vaporization, abrasion, or destruction. Methods used include heating tissue by hot liquids or microwave thermal heating, freezing (CRYOABLATION), chemical ablation, and photoablation with LASERS.

Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. It is inherited as an X-linked or autosomal recessive defect. Mutations occurring in many different genes cause human Severe Combined Immunodeficiency (SCID).

Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged.
