What Is Biliary Reconstruction?
Biliary reconstruction refers to surgical procedures that create or restore a connection between the bile ducts and the intestine so that bile produced by the liver can flow normally into the digestive tract.
When Is Biliary Reconstruction Performed?
1. When the Bile Duct Has Been Injured
- Laparoscopic cholecystectomy (gallbladder removal)
- Open cholecystectomy
- Other abdominal surgeries
- Abdominal trauma
2. Stricture and Obstruction of Bile Duct
- Bile duct stones or strictures (choledocholithiasis)
- Gallstones or gallbladder-related strictures (Mirizzi Syndrome)
- Liver stones or infection (hepatolithiasis/cholangitis)
- Bile duct cysts (choledochal cysts)
- Congenital abnormalities of the bile ducts (biliary atresia)
- Bile duct cancer (biliary cancer)
- Gallbladder cancer
- Chronic pancreatitis
3. During or After Other Major Operations
- Whipple's procedure
- Surgery for gallbladder cancer
- Advanced pancreatic cancer surgery
- Liver resection
- Liver transplantation
- During liver transplantation (hepaticojejunostomy)
- Treatment of complications after liver transplantation (redo hepaticojejunostomy)
What Are the Types of Biliary Reconstruction?
- Hepaticojejunostomy / Roux-en-Y Hepaticojejunostomy: The bile duct is connected directly to the small intestine, usually the jejunum, to allow bile to drain into the intestine.
- Loop Hepaticojejunostomy: A loop of the small intestine is brought up and connected to the hepatic bile ducts.
- Choledochoduodenostomy: The common bile duct is connected directly to the duodenum.
- Portoenterostomy / Kasai Operation: This procedure is mainly used for biliary atresia, a congenital condition in which the bile ducts are absent or severely damaged. The intestine is connected to the area at the liver's porta hepatis to allow bile drainage.

Important Principles of Biliary Reconstruction
Several factors are important for a successful reconstruction:
- The surgeon must clearly identify all the proximal bile ducts.
- All ducts should be incorporated in the anastomosis.
- The connection should be positioned appropriately: upward connection/high up anastomosis.
- Connection of the esophageal mucosa with the biliary duct mucosa (mucosa to mucosa anastomosis).
- Tension-free anastomosis.
Possible Complications of Biliary Reconstruction
Possible complications include:
- Bile leakage
- Bleeding
- Ischemia (reduced blood supply) of the bile ducts
- Cholestasis (reduced or blocked bile flow)
- Anastomotic stricture (narrowing at the surgical connection), reported in approximately 4% to 10% of cases
- Secondary biliary cirrhosis
- Biloma
- Abscess
- Sepsis/Septicemia
- Peptic ulcer disease
Conclusion
- Biliary reconstruction is a complex procedure that can be life-saving when normal bile drainage has been severely disrupted.
- The operation must be performed according to established surgical principles.
- Repeated biliary reconstruction can be difficult and may have adverse effects.
- Narrowing at the surgical connection, known as an anastomotic stricture, is an important post-operative complication and requires regular follow-up.
- Better outcomes are generally associated with experienced hepatobiliary surgeons and specialized centers equipped to manage complex biliary disease.
