Cirrhosis - Diagnosis
Screening for HCV. In the March 16, 2004 issue of the Annals of Internal Medicine, the U.S. Preventive Services Task Force recommended against routine screening for the HCV infection in the general population due to low prevalence of the disease. In addition, it "found no evidence that screening for HCV infection in adults at high risk leads to improved long-term health outcomes" and found insufficient evidence to recommend for or against such screening. However, the Task Force did advise testing in those with signs or symptoms of liver disease. The failure to recommend testing in the high-risk population goes against current recommendations made by CDC, NIH and other professional organizations. In response to the study, The American Association for the Study of Liver Diseases issued a statement saying that halting such screening would be a "terrible mistake with grave consequences," pointing out that the study itself underscored some key infection-related data which strongly emphasizes the need for screening in high-risk populations. BiopsyA liver biopsy is the only definite method for diagnosing cirrhosis. It also helps determine its cause, treatment possibilities, the extent of damage, and the long-term outlook. For example, hepatitis C patients who show no significant liver scarring when biopsied appear to have a low risk for cirrhosis. The biopsy may be performed using various approaches including the following: - Percutaneous Liver Biopsy. This approach uses a needle inserted through the abdomen to obtain a tissue sample from the liver. Various forms of needles are used, including those that use suction or those that cut out the tissue. If cirrhosis is suspected, a cutting needle is the better tool. This approach should not be used in patients with bleeding problems, and it must be used with caution in patients with ascites or severe obesity.

- Transjugular Liver Biopsy. This approach uses a catheter (a thin tube) that is inserted in the jugular vein in the neck and threaded through the hepatic vein (which leads to the liver). A needle is passed through the tube and a suction device collects liver samples. This procedure is risky but may be used for patients with severe ascites.
- Laparoscopy. This procedure employs small abdominal incision through which the physician inserts a thin tube that contains small surgical instruments and a tiny camera to view the surface of the liver. This is generally reserved for staging cancer or for ascites with unknown causes.
