Duodenal Biliary Drainage

Back

A procedure used to diagnose gallstones when suspicion is high but other tests are negative. A thin tube is passed through a nostril down the throat, through the esophagus and stomach, into the duodenum. ... Itcauses the gallbladder to contract and squeeze out bile into the duodenum.

SYMPTOMS

If you are suffering symptoms of a blocked bile duct, such as skin discolouration, itching, nausea and tiredness, a biliary drainage may relieve some of thesesymptoms over time (it often takes a number of days after the procedure for these benefits to become apparent)

CAUSES

The second is that the particles passing through the bile ducts "irritate" the ducts,causing spasm of the muscle within the walls of the ducts (which obstructs the duct) or causing inflammation of the duct so that the wall of the duct swells (which also obstructs the duct).
