liver biopsy

Liver biopsy refers to the operation of cutting a small piece of liver disease tissue for pathological examination in order to clarify the nature of liver disease. It is safer than liver biopsy and has a high positive rate. Treatment of diseases: liver disease Indication 1. In order to confirm or judge the nature of liver lesions, such as tumors, hard changes, and the like. 2. Used to understand the pathological changes of intrahepatic capillary bile duct during bile duct surgery. Surgical procedure When taking the edge of the liver, use the long round needle 7-0 line to suture two stitches on both sides of the lesion, that is, the needle from the liver side of the lesion, the needle from the liver, the wound to the edge of the liver, and then from the liver. The needle at the midpoint between the first needle and the liver margin penetrates the needle of the liver and knots at the edge of the liver. Then, a needle is also sewn on the opposite side of the lesion, so that the two needle sutures are formed into a shape on the liver, and the two knots are not cut off at the same time. The diseased tissue is cut by a sharp-edged knife wedge, and the sutures on both sides are tied and knotted. When there is no cirrhosis, the knotting force should not be too large to prevent the liver tissue from being cut by the suture. In the case of cirrhosis, at the time of liver biopsy, the excised tissue should include 2 hardened nodules. If there is bleeding, you can add suture, hot compress or gelatin sponge compression to stop bleeding. If the lesion is located in the central part of the liver, it can be resected in a fusiform shape, and the needle is sutured by a large round needle. The needle hole is preferably 0.5 to 1 cm from the margin.
