What Is a Bile Duct Injury?
The bile ducts carry bile from the liver to the intestine. They are essential for normal digestion and many important functions of the liver. The bile ducts can be injured for several reasons. A bile duct injury can cause serious complications and, in severe cases, can become life-threatening.

Causes of Bile Duct Injury
Bile duct injuries can occur:
- During laparoscopic or open cholecystectomy (gallbladder removal). It's estimated that this occurs in approximately 0.5%–1% of cases.
- During surgery involving the stomach, duodenum, liver, pancreas, or colon.
- After abdominal trauma, such as: penetrating/blunt trauma.
Why Do Bile Duct Injuries Occur?
Bile duct injuries may occur due to several different reasons. Possible causes include:
- Congenital abnormalities of the bile ducts (developmental biliary anomaly).
- Difficulty correctly identifying the anatomy during laparoscopic cholecystectomy (unclear anatomy).
- Severe gallbladder inflammation or infection (severe cholecystitis).
- Technical or equipment-related problems.
Symptoms and Complications of Bile Duct Injury
A bile duct injury may cause:
- Bile leakage, biloma (a collection of leaked bile) and biliary peritonitis (inflammation of the abdominal lining caused by bile leakage).
- Bile duct obstruction.
- Jaundice, fever and itching.
- Septicemia.
- Secondary biliary cirrhosis.
When Should Bile Duct Injury Be Suspected?
A bile duct injury should be considered when symptoms develop:
- After laparoscopic cholecystectomy.
- After open cholecystectomy.
- After other abdominal surgery.
- After abdominal trauma.
Tests for Bile Duct Injury
Evaluation may include:
- Abdominal ultrasound.
- Liver function tests.
- Other blood tests.
- Coagulation and Renal profile.
- MRCP.
- ERCP.
- Careful examination must be conducted to check whether the esophagus and blood vessels, in addition to the bile duct, have sustained any injury or trauma (vascular and gastro-intestinal tract injury).
Treatment of Bile Duct Injury
The main goal of treatment is to restore bile flow from the liver to the intestine as quickly and safely as possible.
Treatment may include:
- Biliary reconstruction, connecting the bile ducts to the intestine to restore bile drainage.
- Liver resection and biliary reconstruction in highly complex cases.
- ERCP and bile duct stenting.
Prevention of Bile Duct Injury
- Take extreme care during laparoscopic or open cholecystectomy to correctly identify the bile ducts and surrounding structures and prevent injury to the bile ducts.
- Use the same level of caution during other abdominal surgeries.
- If the anatomy cannot be safely identified during laparoscopic cholecystectomy, the surgeon may need to change the surgical approach, including converting to an open procedure when appropriate.
Conclusion
- Bile duct injury can have serious physical, emotional, financial, and social consequences for a patient.
- Every appropriate precaution should be taken to prevent bile duct injury.
- Early diagnosis and timely referral to an experienced hepatobiliary and pancreatic (HPB) surgeon are essential so that the patient can receive appropriate treatment as early as possible.
