Propensity-matched study: urgent ERCP 0.5% vs 21% mortality
Clear mortality benefit for early drainage
ASGE guideline supports within 48 hours for moderate
Emergent vs urgent ERCP in severe cholangitis
Meta-analysis showed no significant difference in mortality
Adequate resuscitation before procedure improves outcomes
Recurrence prevention
Cholecystectomy if choledocholithiasis etiology
Same admission preferred
Within 2-4 weeks if not same admission
Stent exchange programs
Plastic stents require exchange every 3 months
Metal stents for malignant obstruction longer patency
PSC management
Ursodeoxycholic acid for PSC patients
Endoscopic dilation for dominant strictures
Patient Discharge Instructions
copy discharge instructions
Ascending Cholangitis home care
Antibiotics taken exactly as prescribed until finished
Rest at home for 1-2 weeks or as directed by your team
Low-fat diet initially to reduce biliary stimulation
High-fiber diet long-term to reduce gallstone recurrence
Adequate hydration to prevent bile sludging
No alcohol during antibiotic course and for 48 hours after
Stent or drain care (if applicable)
External biliary drain care instructions from nursing team
Signs of drain malfunction: decreased or absent drainage
Keep stent exchange appointment as scheduled (approximately every 3 months for plastic stents)
Warning signs to return to ER immediately
Fever, chills, or rigors returning
Worsening or new abdominal pain
Skin or eyes turning yellow (jaundice)
Dark urine or pale clay-colored stools
Nausea or vomiting preventing oral intake
Confusion, unusual sleepiness, or feeling faint
Shaking chills (rigors)
Follow-up appointments
GI or liver doctor follow-up within 1-2 weeks
Repeat blood tests to confirm liver enzyme improvement
Cholecystectomy (gallbladder removal) appointment if recommended by your surgeon
Next ERCP or biliary procedure as planned by your gastroenterologist
Diet and lifestyle
Start with clear fluids and advance to low-fat solid foods as tolerated
Avoid fatty, fried, or greasy foods for at least 4-6 weeks
Small frequent meals are better tolerated
Stay well hydrated with water and clear fluids
Medication instructions
Complete the full antibiotic course even if feeling better
Do not take NSAIDs (ibuprofen, naproxen) without checking with your doctor
Acetaminophen (Tylenol) is safe for pain relief at recommended doses
