Biliary Ductal Dilatation
Biliary Ductal Dilatation: The ducts of the bile from the gallbladder and liver join together to from a common bile duct. This drains into the small bowel and bile is delivered to this point of the small bowel known as the duodenum. Bile aids in the breakdown of food that is undigested. When there is a blockage occurring in the bile duct, these bile ducts turn out to be enlarged and this is referred to as dilated.
Obstruction or dilatation of the bile duct may happen for many reasons as well as always deserves further examination. Common causes consist of gallstones that get disturbed and dislodged from the gallbladder and journeys thru the bile duct to the area where it empties into the duodenum. This is the slimmest portion of the bile duct and often can get impacted or blocked by gallstones at this position. This zone is likewise the area at where the pancreas is drained into the duodenum.
Most individuals with bile ducts dilatation will need an ERCP or “endoscopic retrograde cholangio-pancreatiogram”. This is a test done usually as a process during the day with no hospital stay and is done under sedation that is heavy. It involves injecting dye that goes from the small bowel into the bile duct. During the test, tumors can be biopsied, stones can be removed from the bile duct, and the obstruction can be relieved. Also, an MRCP which is an MRI scan of these bile ducts may further define the reason for these bile ducts to become dilated but is of only diagnostic value. A bile duct that is only slightly dilated can be seen in an individual who have had a previous cholecystectomy and does not need any further investigation. Most other cases of bile ducts dilatation will need referral to a gastroenterologist who concentrates in the technique of ERCP.
