What causes biliary fistula?
Biliary fistulas are rare complications of lithiasis or neoplasia and are classified as primary and secondary [2]. Internal fistulas are always caused by inflammation and occur mainly as late complications of gallstone or hydatid diseases, like biliobronchial fistulas [3].
What is the first duct that bile enters?
When the liver cells secrete bile, it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts. These ducts ultimately drain into the common hepatic duct. The common hepatic duct then joins with the cystic duct from the gallbladder to form the common bile duct.
What is biliary enteric fistula?
Biliary fistulas are defined as chronic pipe-like ulcers. They can connect the gallbladder with the biliary tree and rarely involve the gastrointestinal tract (internal fistulas) and the abdominal wall (external fistulas) [1.
Where is the biliary enteric fistula?
A biliary fistula is a type of fistula in which bile flows along an abnormal connection from the bile ducts into nearby hollow structure. Types of biliary fistula include: bilioenteric fistula: abnormal connection to small bowel, usually duodenum.
What are the steps of the biliary system?
There are three important functions of the biliary system: Draining the waste products from the liver (into the duodenum) Secreting bile in a controlled-release manner. Transporting bile and pancreatic juices to help break down food in the small intestine.

What is the correct order for the layers of the GI tract wall from innermost to outermost?
The GI tract contains four layers: the innermost layer is the mucosa, underneath this is the submucosa, followed by the muscularis propria and finally, the outermost layer – the adventitia. The structure of these layers varies, in different regions of the digestive system, depending on their function.
What is biliary anastomotic leak?
Biliary anastomotic leak was defined as bile within an intra- or postoperatively placed percutaneous intraperitoneal drain and/or a radiologically confirmed anastomotic leak.
What is biliary bypass surgery?

During this 46 year period, 11,808 patients were operated upon for nonmalignant biliary tract disease, representing an incidence of biliary enteric fistulas of 0.9 per c …
How is a biliary fistula diagnosed?
Patients with suspected biliary fistulas often undergo abdominal ultrasonography or computed tomography (CT) to look for evidence of a biloma, as well as a hepatobiliary iminodiacetic acid (HIDA) scan to diagnose the leak. However, direct cholangiography (most often by ERCP) is the most sensitive test to detect a biliary fistula. 27
What are the different types of biliary fistula?
Types of biliary fistula include: bilioenteric fistula: abnormal connection to small bowel, usually duodenum. thoracobiliary fistula: abnormal connection to pleural space or bronchus (rare). bronchobiliary fistula: pathological communication between a bronchus and the biliary tract (extremely rare).
