Key facts

Bile duct injuries at a glance.

A short, plain-English summary of what a bile duct injury is, how common it is, how it presents and where it is best treated in the UK.

  • What it is

    Damage to the bile ducts, most often iatrogenic during laparoscopic cholecystectomy, but also seen after liver resection, transplantation, ERCP and abdominal trauma.

  • How common

    Around 0.3 to 0.6% of laparoscopic cholecystectomies, roughly three times higher than the open era. Rarer after liver resection, ERCP or trauma.

  • Classification

    Strasberg A to E for post-cholecystectomy injuries; Bismuth-Corlette used for hilar strictures. The pattern drives management.

  • Presentation

    Recognised intraoperatively (best), early postoperative bile leak with sepsis at days 3 to 7, or late obstructive jaundice weeks to years later.

  • Imaging

    MRCP is the gold-standard non-invasive road map; ERCP and PTC are both diagnostic and therapeutic depending on continuity.

  • Where to be treated

    Outcomes are markedly better at specialist HPB centres. Early referral, before repeated attempts at repair, is the single most important decision.

Why this guide matters

Early recognition changes the story.

The pattern of injury, the timing of recognition and the experience of the team who first repairs it all shape the long-term outcome.

  • Most are iatrogenic

    Around 0.3 to 0.6% of laparoscopic cholecystectomies, roughly three times higher than the open era, plus a smaller share after liver resection, ERCP and trauma.

  • Classification guides treatment

    The Strasberg system (A to E) and the Bismuth-Corlette classification for hilar strictures determine whether endoscopic, radiological or surgical management is right.

  • Specialist HPB care is standard

    Definitive repair at a specialist HPB centre, after sepsis and inflammation have settled, delivers substantially better long-term outcomes than repeated local attempts.

How the diagnosis is made

From suspicion to a defined operative plan.

The steps a UK surgical team will normally follow, in order, so you know what to expect and why each step matters.

  1. 01

    Suspecting

    Recognise the picture

    Suspect a bile duct injury in any patient with unexplained pain, fever, jaundice, wound bile or biliary drainage after biliary or upper GI surgery.

  2. 02

    Suspecting

    Bloods and LFTs

    Obstructive pattern with raised ALP, GGT and bilirubin; inflammatory markers and lactate assess sepsis burden.

  3. 03

    Suspecting

    Ultrasound and CT

    Fast bedside triage for biloma, free fluid, abscess, ductal dilation and any coexistent vascular injury or ischaemia.

  4. 04

    Confirming

    MRCP

    The gold-standard non-invasive study to map ductal anatomy, identify the level of injury and plan reconstruction.

  5. 05

    Confirming

    HIDA if leak uncertain

    Hepatobiliary scintigraphy can confirm a bile leak when imaging is equivocal and continuity is preserved.

  6. 06

    Confirming

    ERCP or PTC

    ERCP defines and often treats partial injuries (Strasberg A and D). PTC is used where the duct is transected and ERCP cannot reach the proximal system.

  7. 07

    Referring

    Urgent HPB referral

    Transfer to a specialist HPB centre without repeated local repair attempts. Outcomes are significantly better when definitive care is delivered by an experienced HPB team.

Typical timeline: suspicion to specialist HPB centre in hours to days, not weeks.

Symptoms

What a bile duct injury looks like.

Early leaks, later obstruction and the features that mean urgent HPB input, not another round of local investigation.

  • Bile leak and biloma

    Localised bile collection or free intraperitoneal bile causing pain, fever, ileus and rising inflammatory markers.

  • Biliary peritonitis

    Diffuse abdominal pain, guarding and sepsis from unrecognised leakage; a surgical emergency.

  • Wound or drain bile

    Bilious drainage from a surgical drain, wound or T-tube in the days after surgery.

  • Obstructive jaundice

    Yellow skin and sclerae, dark urine, pale stools and pruritus from partial or complete duct occlusion.

  • Recurrent cholangitis

    Charcot triad of fever, jaundice and right upper quadrant pain from stricture-related bile stasis and infection.

  • Late anastomotic stricture

    Progressive jaundice or cholangitis months to years after reconstruction, from scar-based narrowing at the join.

  • Secondary biliary cirrhosis

    Long-standing untreated obstruction can drive biliary fibrosis, portal hypertension and, in extremis, liver failure.

  • Red flag - sepsis and coagulopathy

    Hypotension, confusion, oliguria or deranged clotting mean urgent resuscitation, source control and HPB involvement.

Treatment

How bile duct injuries are treated in the UK.

Source control first, then classification-led endoscopic, radiological or surgical treatment at a specialist HPB centre, with a multidisciplinary team behind every decision.

  • Intraoperative repair by HPB surgeon

    When recognised at the index operation and an experienced HPB surgeon is available, primary repair gives the best long-term outcome.

  • Drain, close and refer

    If the operating surgeon is not HPB-trained, place a drain, close the abdomen and transfer immediately. Do not attempt an unfamiliar repair.

  • ERCP with sphincterotomy and stent

    First-line for minor leaks (Strasberg A) and many lateral duct injuries (D); combined with percutaneous drainage of any biloma.

  • Percutaneous drainage of biloma

    Image-guided drainage of collections controls sepsis and buys time before definitive reconstruction.

  • PTC and internal-external drainage

    Used for complete transections or hilar strictures where ERCP cannot reach the proximal ducts; also supports later reconstruction.

  • Roux-en-Y hepaticojejunostomy

    The definitive operation for major injuries (Strasberg E1 to E5) at a specialist HPB centre, usually delayed 6 to 8 weeks until sepsis and inflammation settle.

  • Vascular assessment and revascularisation

    Right hepatic artery injury coexists in around 25% of cases; angiography, selective revascularisation and, if needed, hepatic resection of ischaemic segments.

  • Liver transplantation

    Reserved for end-stage secondary biliary cirrhosis or unreconstructable hilar injury with liver failure; selective listing at a UK transplant centre.

UK specialist HPB centres

Experienced UK centres for bile duct injury reconstruction include the Royal Free, King’s College Hospital, Addenbrooke’s, Queen Elizabeth Hospital Birmingham, the Freeman in Newcastle, St James’s in Leeds, Manchester Royal Infirmary, the Royal Infirmary of Edinburgh and the Northern General in Sheffield.

Red flags

When a bile duct injury needs urgent action.

These are the features that should prompt urgent imaging, admission and an HPB conversation rather than watchful waiting.

  • Postoperative sepsis

    Fever, tachycardia, hypotension or rising lactate after biliary surgery warrants urgent imaging, drainage and HPB discussion.

  • Bile in a drain or wound

    Any bilious fluid after cholecystectomy or hepatobiliary surgery is a bile leak until proven otherwise.

  • Progressive jaundice

    Rising bilirubin after biliary surgery, or new jaundice weeks to years later, needs MRCP and specialist review.

  • Cholangitis

    Charcot triad or Reynolds pentad requires IV antibiotics, resuscitation and urgent biliary drainage.

  • Coexistent vascular injury

    Right hepatic artery injury coexists in around 25% of major bile duct injuries and changes both prognosis and operative plan.

  • Repeated failed local repairs

    Each failed attempt worsens the eventual outcome. Refer to a specialist HPB centre before, not after, further intervention.

  • Signs of secondary biliary cirrhosis

    Ascites, variceal bleeding, encephalopathy or synthetic failure in a patient with a known duct injury needs hepatology and transplant input.

  • Duty of candour

    A recognised complication still requires open, timely disclosure to the patient and family under GMC and NHS duty-of-candour standards.

  • Delayed presentation

    A well-looking patient discharged after cholecystectomy can decompensate rapidly on days 3 to 7. Have a low threshold for reassessment.

Living with it

A staged recovery, supported for the long term.

Four things that make the biggest difference: respect the staged plan, keep up long-term surveillance, protect the liver and accept help with the psychological weight of an iatrogenic complication.

A quiet reminder

Specialist care first, everything else second.

The most consistent predictor of a good long-term outcome is that definitive care is delivered by an experienced HPB team, not the speed of the first repair.

  1. 01 Recovery

    Expect a staged journey

    Sepsis and drainage first, imaging next, definitive reconstruction later. Trying to shortcut the sequence usually makes outcomes worse.

  2. 02 Follow-up

    Long-term surveillance

    After reconstruction, LFTs and clinical review at set intervals to catch anastomotic stricture, cholangitis or biliary cirrhosis early.

  3. 03 Lifestyle

    Alcohol, weight and diet

    Protecting the liver matters. Modest alcohol intake, a healthy weight and prompt treatment of infections all reduce long-term risk.

  4. 04 Support

    Psychological impact is real

    Iatrogenic injury can carry significant psychological weight. Specialist nurse and psychology support is part of a modern HPB pathway.

Frequently asked

Everything we get asked about bile duct injuries.

Quick answers on classification, imaging, reconstruction and where to be treated in the UK.

  • What is a bile duct injury?

    A bile duct injury (BDI) is damage to one of the ducts that carry bile from the liver to the intestine. Most are iatrogenic, occurring during laparoscopic cholecystectomy in around 0.3 to 0.6% of cases, but they can also follow open cholecystectomy, liver resection, transplantation, ERCP or blunt or penetrating abdominal trauma.

  • How are bile duct injuries classified?

    Injuries after cholecystectomy are usually classified using the Strasberg system, A to E: A is a cystic duct or duct of Luschka leak, B is occlusion of an aberrant right hepatic duct, C is transection of an aberrant right hepatic duct, D is a lateral injury to a major duct, and E1 to E5 describe transections or strictures of the common hepatic or common bile duct at varying levels. Hilar strictures are described using the Bismuth-Corlette classification. The pattern determines whether endoscopic, radiological or surgical treatment is appropriate.

  • How does a bile duct injury present?

    There are three typical windows. Intraoperatively, an alert surgeon sees bile where it should not be, and only 15 to 40% of injuries are recognised at the index operation. Early postoperatively (days 3 to 7), patients develop biloma, bile peritonitis, wound bile, fever, jaundice and sepsis. Late presentations, weeks to years afterwards, are dominated by obstructive jaundice, recurrent cholangitis and, if untreated, secondary biliary cirrhosis and portal hypertension.

  • What investigations are needed?

    Liver function tests show an obstructive pattern. Ultrasound and CT identify biloma, free fluid and ductal dilation. MRCP is the gold-standard non-invasive road map of the biliary tree. HIDA scanning can confirm an ongoing leak. ERCP is both diagnostic and therapeutic for minor leaks and lateral injuries, while PTC is used when the duct is completely transected and ERCP cannot reach the proximal system. All patients should be discussed urgently with a specialist HPB centre.

  • How is a major bile duct injury repaired?

    For Strasberg E1 to E5 injuries, the definitive operation is a Roux-en-Y hepaticojejunostomy performed at a specialist HPB centre. It is usually delayed for around 6 to 8 weeks to allow sepsis, biloma and inflammation to settle, giving the reconstruction the best chance of long-term patency. Coexistent right hepatic artery injury, present in around 25% of cases, is assessed with angiography and managed with selective revascularisation or, occasionally, hepatic resection of ischaemic segments.

  • Where in the UK are these injuries best managed?

    UK HPB centres experienced in BDI reconstruction include the Royal Free, King’s College Hospital, Addenbrooke’s, Queen Elizabeth Hospital Birmingham, the Freeman in Newcastle, St James’s in Leeds, Manchester Royal Infirmary, the Royal Infirmary of Edinburgh and the Northern General in Sheffield. The single most important decision is early referral, before repeated local repair attempts, because outcomes and long-term liver function are substantially better when definitive care is delivered by an experienced HPB team.
