Algorithm Steps

1. ▶

   Start

   Suspected Post-Cholecystectomy Bile Leak

   Bilious drain output or clinical deterioration

   1. ●

      Action

      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
      1. ●

         Action

         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

            Signs of Sepsis/Peritonitis?

            Determines urgency

            1. ⚠

               Warning

               Urgent Source Control

               Septic patient - drain first

               • Antibiotics STAT
               • CT-guided percutaneous drainage of collections
               • Resuscitation
               • THEN proceed to ERCP once stable
               1. ●

                  Action

                  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
                  1. ◆

                     Decision

                     ERCP Successful?

                     Assess leak resolution

                     1. ●

                        Action

                        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

                           Outcome

                           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
                     2. ●

                        Action

                        PTC Drainage

                        If ERCP fails

                        • Percutaneous transhepatic cholangiography
                        • External biliary drainage
                        • Controls leak while awaiting definitive Rx
                        • May convert to internal drainage
                     3. ●

                        Action

                        Surgical Intervention

                        Rarely needed for isolated leak

                        • Indications:
                        • - Failed endoscopic/percutaneous Rx
                        • - Major duct injury (Strasberg E)
                        • - Ongoing peritonitis
                        • Options: Repair, drain, hepaticojejunostomy
            2. ◆

               Decision

               Leak Volume Assessment

               Guides management approach

               • Low output: <200 mL/day
               • High output: >200 mL/day
               1. ●

                  Action

                  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
               2. ●

                  Action

                  High-Output Leak

                  Requires intervention

                  • ERCP recommended
                  • Unlikely to resolve spontaneously
                  • NPO, IV fluids
                  • Keep drain for controlled fistula
