What are the contraindications for Percutaneous Transhepatic Biliary Drainage (PTBD), Endoscopic Retrograde Cholangiopancreatography (ERCP), and cholecystectomy in a patient with cholangitis?

Contraindications for PTBD, ERCP, and Cholecystectomy in Cholangitis

ERCP is the preferred first-line drainage procedure for cholangitis with minimal absolute contraindications, while PTBD should be reserved for ERCP failures and is absolutely contraindicated in uncorrected coagulopathy, and cholecystectomy timing depends on cholangitis severity with drainage taking priority over surgery in acute settings. 1, 2

ERCP Contraindications

Absolute Contraindications

• Patient inability to tolerate anesthesia or sedation 1
• Suspected or confirmed gallbladder perforation with biliary peritonitis 1
• Hemodynamic instability requiring immediate resuscitation (though ERCP should follow rapidly after stabilization) 2, 3

Relative Contraindications

• Coagulopathy - However, ERCP remains the procedure of choice even in coagulopathy because bleeding risk is significantly lower than PTBD 1
  • Bleeding risk with therapeutic ERCP is 1-2%, primarily from sphincterotomy 1
  • Alternative techniques like balloon sphincteroplasty can be used when coagulopathy cannot be corrected 1
• Large-volume ascites - This is more of a contraindication for PTBD; ERCP can still be performed 1
• Surgically altered anatomy - This makes ERCP technically difficult but not impossible with advanced techniques like balloon enteroscopy-guided drainage 4, 5

Technical Limitations (Not True Contraindications)

• Anatomically inaccessible papilla - May require EUS-guided biliary drainage or PTBD as alternatives 6, 4
• Upper gastrointestinal obstruction - May prevent endoscope passage 4

PTBD Contraindications

Absolute Contraindications

• Uncorrected coagulopathy - PTBD carries approximately 2.5% bleeding risk in normal patients, which increases substantially with coagulopathy 1, 6
• Inability to tolerate anesthesia 1

Relative Contraindications

• Moderate to massive ascites - Initial access into ducts becomes technically challenging and increases complication risk 1
• Nondilated biliary system - Makes technical success more difficult, though still achievable with skinny needle techniques 7

Complications That Make PTBD Less Desirable

PTBD carries significant risks including: 2, 6

• Biliary peritonitis
• Hemobilia
• Pneumothorax
• Hematoma
• Liver abscesses
• Patient discomfort from external catheter

Critical Point: PTBD should only be used when ERCP fails or is not feasible (Recommendation 1B), not as a first-line approach 1, 2, 6

Cholecystectomy Contraindications in Cholangitis Setting

Timing-Based Contraindications

• Active severe (Grade III) cholangitis - Biliary drainage must be performed first; cholecystectomy is deferred until sepsis resolves 2, 8, 3
• Active moderate (Grade II) cholangitis - Early biliary drainage within 24 hours takes priority over cholecystectomy 2, 8, 3

Patient-Based Contraindications

• Critically ill patients with multiple comorbidities unfit for surgery - These patients should receive cholecystostomy instead 1
• Hemodynamic instability despite resuscitation 8, 3
• Severe septic shock - Requires ICU admission, antibiotics within 1 hour, and urgent biliary drainage, not cholecystectomy 2, 8

Anatomic Contraindications

• Gallbladder perforation with diffuse peritonitis - May require open surgical drainage rather than laparoscopic approach 1

Hierarchical Drainage Algorithm for Cholangitis

First-line: ERCP with stent or nasobiliary drain placement (Recommendation 1A) 1, 2, 6

• Success rate >90%, adverse events ~5%, mortality <1% 2

Second-line: PTBD when ERCP fails or is not feasible (Recommendation 1B) 1, 2, 6

Third-line: Open surgical drainage only when both endoscopic and percutaneous approaches are contraindicated or have failed (Recommendation 2C) 1, 6

Emerging alternative: EUS-guided biliary drainage after failed ERCP, particularly useful in altered anatomy 4, 5

Common Pitfalls to Avoid

• Attempting PTBD as first-line when ERCP is feasible - This exposes patients to unnecessary complications 2, 6
• Delaying biliary drainage in severe cholangitis - Dramatically increases mortality; drainage should occur as soon as possible after initial stabilization 2, 6, 3
• Performing cholecystectomy before biliary drainage in active cholangitis - Biliary decompression must take priority 9, 3
• Failing to correct coagulopathy before PTBD - This significantly increases bleeding risk 1
• Delaying antibiotics - Must be given within 1 hour for septic shock or 4-6 hours for less severe cases 2, 8
