Management of bleeding liver tumors

Area of Science:

• Hepatology
• Interventional Radiology
• Surgical Oncology

Background:

• Liver tumors rarely bleed, but when they do, management has shifted from emergency surgery to a multidisciplinary approach.
• Historically, emergency surgery for bleeding liver tumors yielded poor outcomes.
• Recent advancements emphasize timely diagnosis and minimally invasive interventions.

Purpose of the Study:

• To outline the current multidisciplinary management strategy for bleeding liver tumors.
• To detail diagnostic and therapeutic steps for acute bleeding and underlying tumor management.
• To differentiate treatment pathways based on tumor type and patient stability.

Main Methods:

• Initial assessment includes abdominopelvic CT scan to diagnose and control bleeding.
• Arterial embolization is the preferred treatment for active bleeding when hemodynamically stable.
• Surgery, specifically abbreviated laparotomy (damage control) with perihepatic packing, is reserved for severe instability or embolization failure.

Main Results:

• Diagnosis of the underlying tumor, commonly adenoma or hepatocellular carcinoma (HCC), is crucial after bleeding control.
• Liver MRI aids diagnosis, though hematoma may complicate interpretation.
• Resection is indicated for HCC, atypical adenomas, or potentially malignant lesions; benign adenomas require observation until hematoma resolution.

Conclusions:

• Multidisciplinary management, integrating interventional radiology and surgery, has significantly improved outcomes for bleeding liver tumors.
• Timely diagnosis and selective arterial embolization are key to managing acute bleeding.
• Etiological diagnosis and appropriate tumor-specific treatment, including resection or observation, are essential for long-term patient care.
