Surgical Management of Hepatocellular Carcinoma with Biliary Complications

The surgical management of hepatocellular carcinoma complicated by bile duct involvement presents unique challenges that encompass tumour biology, patient physiology and operative technique. Biliary complications such as bile duct tumour thrombus and bile duct invasion exacerbate obstructive jaundice, promote cholangitis and compromise hepatic reserve. Successful intervention requires accurate preoperative assessment of liver function, tumour extent and biliary anatomy, followed by tailored strategies that may include anatomical or non-anatomical hepatectomy, bile duct resection with reconstruction, and, in selected cases, liver transplantation. Multidisciplinary planning is essential, integrating hepatobiliary surgeons, interventional radiologists and anaesthetists to optimise perioperative care and minimise morbidity. Advances in imaging and intraoperative navigation have improved resection margins, while adjunctive techniques such as portal vein embolisation and staged hepatectomy expand the pool of patients eligible for curative surgery. Despite the higher risk of early recurrence, curative resection remains the cornerstone of treatment for selected patients, offering the best chance of long-term survival when complete tumour clearance is achieved without compromising postoperative liver function.

Research from Nature Portfolio

Recent studies have illuminated molecular drivers of bile duct invasion and aided development of targeted strategies to prevent tumour thrombus formation. One investigation employed novel animal models to show that overexpression of a stem‐cell marker in liver progenitor cells promotes bile duct tumour thrombus through enhanced secretion of lysosomal proteases. Pharmacological inhibition of these enzymes markedly reduced intraductal invasion and improved survival in preclinical models. This work suggests that adjunctive medical therapies targeting specific protease pathways may complement surgical resection by reducing the risk of biliary spread and postoperative recurrence.

Surgical Management of Hepatocellular Carcinoma with Biliary Complications publication trend

The graph below shows the total number of articles in surgical management of hepatocellular carcinoma with biliary complications across all publications each year (not limited to Nature Index journals).

Technical terms

Hepatocellular carcinoma (HCC): Primary malignancy of the liver arising from hepatocytes, often in the context of chronic liver disease.

Bile duct tumour thrombus (BDTT): Intraductal extension of tumour tissue into the bile ducts, leading to obstructive jaundice and complicating surgical resection.

Curative hepatic resection: Surgical removal of all detectable tumour with a margin of healthy tissue, aiming for complete eradication of malignancy.

Orthotopic liver transplantation: Replacement of the diseased liver with a donor organ in its normal anatomical position, considered in select cases of HCC.

Bile duct invasion (BDI): Direct tumour infiltration of bile duct walls beyond the lumen, associated with poorer prognosis and complex reconstructive requirements.
