alpps is an emerging hepatectomy procedure that ensures that the tumor is removed and liver failure is prevented, with the potential to completely cure patients with terminal liver cancer. The procedure differs from traditional liver resection in that the surgeon first removes the tumor from the left side of the liver and then cuts off the portal vein of the right side of the liver, reducing the blood supply to the right side of the liver, causing the right side of the liver to shrink due to low blood flow while the left side of the liver grows due to a surge in blood flow. One week after the surgery, the size of the left liver will increase by 70% to 80% compared to its original size. The surgeon will then perform a second hepatectomy to completely remove the right side of the liver, thus removing all the liver tumors. When a liver cancer patient reaches the end stage of the disease and has a large tumor or many tumors of different sizes in the liver, the remaining liver is often very small, resulting in liver failure and death. This prevents patients with liver cancer from dying of liver failure after surgery. Although the surgery does not guarantee that the cancer will not recur, the survival rate is definitely higher than that of traditional liver resection.
