Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action Clinical Presentation
Signs of bile leak
- Bilious output from surgical drain
- Abdominal pain (RUQ, diffuse)
- Fever, tachycardia
- Nausea, anorexia
- Jaundice (if obstruction)
- Typically POD 1-7
03Action Diagnostic Workup
Confirm leak and assess extent
- Labs: LFTs, bilirubin, WBC
- CT abdomen: Fluid collection/biloma
- HIDA scan: Confirms active leak
- MRCP: Ductal anatomy
- Measure drain output volume
04Decision Signs of Sepsis/Peritonitis?
Determines urgency
05Warning Urgent Source Control
Septic patient - drain first
- Antibiotics STAT
- CT-guided percutaneous drainage of collections
- Resuscitation
- THEN proceed to ERCP once stable
06Action ERCP Management
First-line intervention
- Sphincterotomy (reduces pressure gradient)
- ± Biliary stent placement
- Stent bridges leak site if possible
- Removes retained stones if present
- Success rate: 90-95%
- Stent removal in 4-6 weeks
07Decision ERCP Successful?
Assess leak resolution
08Action Monitor for Resolution
Post-intervention care
- Decrease in drain output
- Improving LFTs
- Resolving collections on imaging
- Remove drain when output <50 mL/day
- Follow-up ERCP for stent removal
09Outcome Outcomes
Prognosis
- Cystic duct leak: >95% success with ERCP
- Accessory duct leak: Good prognosis
- Major duct injury: Requires surgical repair
- Mortality: <1% for isolated leak
10Action PTC Drainage
If ERCP fails
- Percutaneous transhepatic cholangiography
- External biliary drainage
- Controls leak while awaiting definitive Rx
- May convert to internal drainage
- Path rejoins step 08Shared downstream outcome
11Action Surgical Intervention
Rarely needed for isolated leak
- Indications:
- - Failed endoscopic/percutaneous Rx
- - Major duct injury (Strasberg E)
- - Ongoing peritonitis
- Options: Repair, drain, hepaticojejunostomy
- Path rejoins step 09Shared downstream outcome
12Decision Leak Volume Assessment
Guides management approach
- Low output: <200 mL/day
- High output: >200 mL/day
13Action Low-Output Leak
May resolve spontaneously
- Keep drain in place
- NPO initially, advance diet as tolerated
- Monitor drain output daily
- Most resolve in 1-2 weeks
- ERCP if no improvement in 5-7 days
- Path rejoins step 06Shared downstream outcome
- Path rejoins step 08Shared downstream outcome
14Action High-Output Leak
Requires intervention
- ERCP recommended
- Unlikely to resolve spontaneously
- NPO, IV fluids
- Keep drain for controlled fistula
- Path rejoins step 06Shared downstream outcome

Clinical Safety Information
Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- Must distinguish leak from major duct injury
- Drain output may be misleading
- ERCP success depends on operator experience
- Delayed presentation more complex
