Overview
Primary intrahepatic lithiasis involves the formation of stones within the liver bile ducts, distinct from extrahepatic biliary tract lithiasis. It often requires specialized interventional radiology or endoscopic approaches for diagnosis and management due to its complexity 4.Diagnosis
Direct cholangiography: Essential for diagnosis, typically performed via percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiopancreatography (ERCP) 4.
Imaging: CT and MRI may provide initial clues but direct visualization is crucial 4.Management
Percutaneous transhepatic stone removal: Highly successful, minimally invasive, and safe method for stone clearance, including fragmentation and removal via baskets 4.
Endoscopic approaches: Considered as alternatives to percutaneous techniques, particularly useful for addressing underlying strictures 4.
Surgical intervention: Reserved for cases where percutaneous or endoscopic methods are not feasible or have failed 4.Special Populations
No specific data provided: The abstracts do not cover primary intrahepatic lithiasis management in pregnancy, pediatrics, elderly, or specific comorbidities 1234.Key Recommendations
Utilize direct cholangiography (PTC or ERCP) for definitive diagnosis of hepatolithiasis 4 (Evidence: Strong).
Percutaneous transhepatic stone removal should be considered as a first-line minimally invasive treatment due to its high success rate in stone clearance 4 (Evidence: Strong).
Evaluate and consider endoscopic techniques as adjunctive or alternative methods, especially for managing associated strictures 4 (Evidence: Moderate).References
