Liver tumors Non cancerous
These do not spread to other parts of the body and need surgical removal if the diagnosis is in doubt or causing symptoms. Hemangiomas are dilated blood channels and if they are incidental finding without any symptom, they can be observed with yearly ultrasounds. They would need surgical removal or blocking the main feeding vessel (Embolization) if causing any symptoms. Focal nodular hyperplasia and adenoma are other non cancerous growths can be observed if the diagnosis is definite.
Hepatoblastoma and hepatocellular carcinoma are the two commonest cancerous tumors in children and adults respectively. Surgical resection is essential for both followed by chemotherapy. Local ablative (burning) therapy using high frequency alternative current (Radiofrequency Ablation) and chemoembolization (Blocking the blood supply for the tumor) can be tried if not suitable for surgery. Liver transplant is an option for unresectable tumors without spread to other parts of the body
Cancer can arise from liver cells (Hepatocellular carcinoma) or spread from other organs such as colon, stomach and pancreas to the liver (Liver metastases). Abdominal pain, weight loss and unexplained fever are the usual presenting symptoms of liver cancer. Liver cancer is more common in people suffering with hepatitis B/C infection or cirrhosis. A stable patient with these conditions can deteriorate suddenly and show jaundice or ascitis when a cancer develops. When diagnosed early, these tumors can be removed by surgery.
For patients whose tumors are successfully resected, the five-year survival is about 30 to 40%. To know more about Liver cancer visit http://www.medicinenet.com
This is caused by echinococcus granulose. This is transmitted to human beings by sheep/dogs. It enters the body by oral route. It can settle any where in the body and the most common sites would be Lungs and liver. It may be silent or present with pain if it is big cyst. It can cause fever, jaundice, itching or swelling of the abdomen. Diagnosis by finding antibodies in the blood and CT scan would easily pick up this bag like structures filled with fluid and cysts. Operative treatment by removal of the cyst followed by medical treatment is the best.
Acute Liver failure
Is a complex multisystem illness that can progress quickly after an insult to the liver leading to brain swelling and other organ failure. The insult can be Medicines like Paracetamol or Herbal Medicines, Virus causing hepatitis (Hep. B,A) or reaction to medication. Some would recover with supportive care but others would not survive without a Liver transplant
Liver transplantation is the only definitive treatment for patients suffering from end stage liver failure or some cases of acute Liver failure. The word transplantation implies to removal of diseased organ and replacement with a healthy one. This is an established method and many people who have had liver transplants now lead normal lives. The liver can be obtained from victims of brain death or from a live donor (a portion of liver). Many of the western countries have an established system for prompt diagnosis and declaration of brain death and to counsel the relatives of the deceased regarding organ donation. These countries also follow a legitimate system of organ allocation to the patients who are wait listed according to prefixed criteria. Majority of the healthy livers for transplantation come from a deceased donor in these countries. This avoids subjecting a healthy live donor to a major surgery. How ever, since the demand for organs is far more than the organs available thousands of patients lose their lives every year. Taking a portion of liver from a live donor can cut down the number of such deaths. Countries like Japan and South Korea have been focusing their efforts on Live donor liver transplantation due to the social and religious constraints faced in establishing system for deceased donor transplantation. These countries have shown excellent results in Live donor transplants
