What is posterior to the common bile duct?
The common bile duct travels initially in the free edge of the lesser omentum, then courses posteriorly to the duodenum and pancreas to unite with the main pancreatic duct to form the ampulla of Vater, which drains at the major duodenal papillae on the medial wall of the D2 segment of the duodenum.
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.
Which part of the common bile duct opens?
👉 For more insights, check out this resource.
The common bile duct is about 6–7 cm long and opens into the duodenum at the ampulla of Vater, having passed through the head of the pancreas and combined with the pancreatic duct.
What is an Enteroenterostomy?
Enteroenterostomy is an anastomosis between one part of the small bowel and another part of the small bowel (jejunum or ileum). It is used to restore bowel continuity after resection of a segment of the bowel or after creation of a Roux-en-Y loop of jejunum or as a part of a Braun loop of jejunum.

Why Hepaticojejunostomy is done?
Hepaticojejunostomy is constructed with the hope of providing adequate drainage to the biliary tract for unimpeded passage of newly formed intrahepatic stones. Intrahepatic strictures proximal to the hepaticojejunal anastomosis impede free drainage of bile and passage of stones.
What are the parts of the common bile duct?
Common Bile duct (CBD), 6.0–8.0 cm long, is generally divided into supraduodenal, retroduodenal, retropancreatic and intraduodenal segments. The supraduodenal CBD lies in the right border of lesser omentum (hepato-duodenal ligament) anterior to portal vein and to the left of hepatic artery proper.
What ducts empty into the common bile duct?
The common hepatic duct and the cystic duct join to form the common bile duct. The cystic duct connects the gallbladder (a small organ that stores bile) to the common bile duct. The common bile duct passes through the pancreas before it empties into the first part of the small intestine (duodenum).
What is Cholecystocholedochal fistula?
Mirizzi syndrome and cholecystocholedochal fistula are two manifestations of the same process that starts with impaction of a gallstone in the gallbladder neck that results in obstruction of the bile duct, causing jaundice. The gallstone may erode into the bile duct, causing cholecystocholedochal fistula.
What causes Hartmann’s pouch?
Hartmann’s pouch is caused by adhesions between the cystic duct and the neck of the gallbladder. As a result, it is classified as a morphologic rather than an anatomic entity [2].
Is the common bile duct part of the gallbladder?
The common bile duct is a small, tube-like structure formed where the common hepatic duct and the cystic duct join. Its physiological role is to carry bile from the gallbladder and empty it into the upper part of the small intestine (the duodenum). The common bile duct is part of the biliary system.
Where do the common bile duct and pancreatic duct empty?
The common bile duct joins with the pancreatic duct to form the ampulla of Vater, which empties into the duodenum.
What is the common bile duct?
The Common Bile Duct is a small tube-like gastrointestinal tract in the organisms that have a gall bladder. The foundation of the bile duct is near the porta hepatis, by the joining of cystic and common hepatic ducts. It measures typically about 7.5 cm (3 inches) in length and about 6 millimeters in diameter. It’s divided into 4 parts:
Where does the superior pancreaticoduodenal artery cross the bile duct?
The superior pancreaticoduodenal artery crosses the bile duct either anteriorly or posteriorly. Medically it’s a source of hemorrhage in the vulnerability of infraduodenal part of the bile duct. Near the middle 2nd part of the duodenum, it comes in touch together with the pancreatic duct.
What is the retroduodenal part of the colon?
Retroduodenal part. Infraduodenal (or pancreatic) part. It’s about 2.5 cm long and descends in the right free margin of the lesser omentum to the right of the hepatic artery appropriate and anterior to the portal vein. It descends behind the initial part of the duodenum with the gastroduodenal artery on its left and IVC on its posterior aspect.
How is bile produced in the gallbladder?
It is produced by the liver and stored and concentrated in the gallbladder until it is needed to help digest foods. When food enters the small intestine, bile travels through the common bile duct to reach the duodenum. Gallstones are hard deposits that form inside the gallbladder when there is too much bilirubin or cholesterol in the bile.
