What is the normal size of the common hepatic duct?
The common hepatic duct (CHD) is formed by the junction of the right and left hepatic ducts. It joins the cystic duct to form the common bile duct (CBD). It is approximately 4 cm long and 4 mm in diameter.
How big is the cystic duct?
The cystic duct usually measures 2–4 cm in length and contains prominent concentric folds known as the spiral valves of Heister. The cystic duct frequently exhibits a tortuous or serpentine course. The normal diameter of the cystic duct is variable, ranging from 1 to 5 mm.
Where is the common bile duct?
A tube that carries bile from the liver and the gallbladder through the pancreas and into the duodenum (the upper part of the small intestine). It is formed where the ducts from the liver and gallbladder are joined. It is part of the biliary duct system.
What is cystic dilatation?
Choledochal cysts, are rare congenital dilations (enlargements) of the bile ducts, a network of long tube-like structures that carry bile from the liver to small intestine for digestion.
What is mirizzi?
Mirizzi syndrome is defined as common hepatic duct obstruction caused by extrinsic compression from an impacted stone in the cystic duct or infundibulum of the gallbladder [1-3]. Patients with Mirizzi syndrome can present with jaundice, fever, and right upper quadrant pain.
What causes bile duct cysts?
Bile Duct Cysts The most widely accepted hypothesis is that cystic dilatation is related to an anomalous arrangement of the pancreaticobiliary junction, with a long common channel that allows reflux of pancreatic juice into the biliary tree causing inflammation, ectasia, and ultimately dilatation [9].
What can block your bile duct?
A blockage in any of these tubes is a bile duct obstruction. The most common cause of a bile duct obstruction is a gallstone. Gallstones form inside the gallbladder and can move into the common bile duct, blocking it. Cysts, tumors, inflammation and scarring are other bile duct obstruction causes.
What does biliary pain feel like?
Symptoms. A person with biliary colic typically feels pain in the middle to right upper abdomen. The pain can feel sharp, crampy, or like a constant dull ache. Colic often occurs in the evening, especially after eating a heavy meal.
How long after eating does gallbladder hurt?
The feeling, which usually occurs in the center of the stomach, can begin anywhere from 30 to 60 minutes after a meal. During that time, the pain may travel from the stomach to the upper abdomen and, at times, may radiate through the back and into the shoulder blade. Pain isn’t the only symptom of a gallbladder attack.
Do gallstones hurt more after eating?
Why Does My Gallbladder Hurt After I Eat?: Gallstones or inflammation of various conditions can cause gallbladder pain after eating. Fatty foods tend to make this pain worse, as they stimulate more activity from the organ.
