Endoscopic bipolar radiofrequency ablation for malignant biliary obstruction
Closed for comments This consultation ended on at Request commenting lead permission
Description
Cancer of the bile duct or pancreas can block the channels that carry bile and digestive fluids from the gall bladder and pancreas to the small intestine (malignant biliary obstruction). This can cause jaundice, nausea, bloating and abdominal pain. The blockage is usually treated by inserting small tubes called stents, which help to keep the channels open and draining properly. But these stents can also become blocked.
In this procedure, a thin tube with a camera on the end (an endoscope) is passed through the mouth to the blockage. A device is then passed through the endoscope and used to deliver heat energy (radiofrequency) to destroy (ablate) the blockage in the channels. This procedure is done before inserting stents or to clear blocked stents. The aim is to reduce symptoms.
