Liver resection, or hepatectomy, removes part of the liver to treat liver cancer, metastatic tumors, or benign conditions like cysts. Symptoms include jaundice, abdominal pain, weight loss, or fatigue. The procedure, often performed open or laparoscopically, removes diseased tissue while preserving healthy liver, which can regenerate. Open surgery is used for larger or complex tumors. Risks include bleeding, infection, or liver failure, particularly in patients with underlying liver disease. Recovery involves a hospital stay and weeks to months of healing, with dietary support for liver regeneration. Follow-ups monitor liver function and cancer recurrence. Chemotherapy or ablation may be needed for cancer cases. The procedure improves survival for early-stage tumors, leveraging the liver’s regenerative ability, though long-term care focuses on maintaining liver health and preventing recurrence.
