Management of Post-Laparoscopic Cholecystectomy Biloma

Rationale for Image-Guided Drainage

The World Society of Emergency Surgery guidelines recommend percutaneous treatment of the collection with drain placement as the appropriate first step for minor bile duct injuries (Strasberg A-D) if no drain was placed during surgery, in patients with confirmed biloma and elevated bilirubin levels, indicating ongoing bile leak 2
Image-guided percutaneous drainage is the most appropriate initial management for patients with post-cholecystectomy biloma and elevated bilirubin levels, to achieve source control and prevent progression to abscess or biliary peritonitis 1, 2

MRCP can be complementary to CT for exact visualization and classification of bile duct injury, but it would delay definitive treatment when the diagnosis is already established, and the WSES guidelines position MRCP as an adjunct to CT, not a replacement for therapeutic intervention 1, 2, 3

The American College of Surgeons and the World Society of Emergency Surgery recommend initiating broad-spectrum antibiotics immediately (within 1 hour) using piperacillin/tazobactam, imipenem/cilastatin, meropenem, or ertapenem, in patients with biloma, to reduce the risk of infection 1, 4
The World Society of Emergency Surgery guidelines suggest monitoring clinical response over 24-72 hours with serial clinical examination and inflammatory markers, in patients with biloma, to assess the effectiveness of treatment 1
If no improvement or worsening occurs, the World Society of Emergency Surgery guidelines recommend proceeding to ERCP with biliary sphincterotomy and stent placement, which becomes mandatory at this stage, to achieve definitive treatment of the bile duct injury 2, 5
The World Society of Emergency Surgery guidelines recommend continuing antibiotics for 5-7 days for biloma management, to ensure complete treatment of the infection 1, 3

The World Society of Emergency Surgery guidelines advise against delaying drainage in symptomatic patients with confirmed biloma, as this risks progression to sepsis, abscess formation, or biliary peritonitis 1, 3
The World Society of Emergency Surgery guidelines warn against assuming the biloma will resolve without intervention, as percutaneous drainage is required for source control, and withholding antibiotics, as patients with biloma require immediate antimicrobial therapy 1, 4, 5
