Percutaneous Drainage in Acute Cholangitis Management

Introduction to Percutaneous Biliary Drainage

The American College of Radiology recommends percutaneous transhepatic biliary drainage (PTBD) as a second-line approach for managing acute cholangitis when endoscopic retrograde cholangiopancreatography (ERCP) fails or is not feasible due to anatomical limitations or unsuccessful biliary cannulation 1, 2

The World Journal of Emergency Surgery suggests ERCP as the first-line and treatment of choice for biliary decompression in patients with moderate to severe acute cholangitis (Recommendation 1A) 1, 3
Percutaneous transhepatic biliary drainage (PTBD) should be used as a second-line approach when ERCP fails or cannot be performed (Recommendation 1B) 2, 4
Open surgical drainage should only be considered when both endoscopic and percutaneous approaches are contraindicated or have failed (Recommendation 2C) 1, 5

Unsuccessful biliary cannulation during ERCP is an indication for percutaneous drainage 2, 3
Anatomically inaccessible papilla (e.g., surgically altered anatomy) is an indication for percutaneous drainage 2
Failed ERCP despite multiple attempts is an indication for percutaneous drainage 4
When emergent decompression is needed and ERCP expertise is unavailable, percutaneous drainage is indicated 6

The timing of biliary decompression is dictated by the severity of acute cholangitis according to the Tokyo Guidelines grading system 7, 6
Moderate (grade 2) cholangitis requires early decompression (within 24 hours) to significantly reduce 30-day mortality 7, 6

Balloon dilation of strictures can be initiated at the time of initial access, though waiting 2-4 weeks after initial access is generally advisable 7
Large caliber catheters should be used to maintain duct patency and determine minimum diameter for scarring after dilatation 7

PTBD carries significant risks including biliary peritonitis 2, 5, hemobilia 2, pneumothorax 2, hematoma 2, liver abscesses 2, and patient discomfort related to external catheter 2

Percutaneous approaches have been shown to facilitate subsequent endoscopic or surgical intervention 2

There is no consensus on the optimal duration of catheter indwell time after dilatation 7
Studies have shown improved patency with stenting for >6 months compared with <4 months without stenting 7

Antibiotics and fluid resuscitation should be initiated promptly before any drainage procedure 6
For patients with sepsis, appropriate antibiotics should be initiated within 1 hour of diagnosis 7
In less severe cases, antibiotics should be administered within 6 hours of diagnosis 7
The focus in severe biliary sepsis should be on biliary decompression with the least manipulation of the biliary tree possible 7
