liver injury repair

1. The area of liver laceration and liver contusion and laceration injury is not large, the wound is not deep, and the tissue necrosis is less. 2. Liver injury does not involve the hepatic hilum or important vascular injury in the liver. Treatment of diseases: vascular injury, liver damage Indication 1. The area of liver laceration and liver contusion and laceration injury is not large, the wound is not deep, and the tissue necrosis is less. 2. Liver injury does not involve the hepatic hilum or important vascular injury in the liver. Preoperative preparation 1. The diagnosis of liver injury is determined and should be explored by laparotomy. For those with shock, prepare for preoperative surgery while actively anti-shock treatment, and operate as soon as possible. 2. Give antibiotics, liver protection drugs, oxygen, gastrointestinal decompression, etc. Surgical procedure The right upper abdomen was incision through the rectus abdominis. After laparotomy, the liver injury was detected while rapidly attracting, clearing blood and blood clots. When the bleeding is fierce, the first hepatic hilum should be controlled through the duodenal ligament through the retina through the retina tube, the liver damage wound should be cleaned, the non-viable tissue should be removed, and the active bleeding blood vessels and bile ducts should be clamped. For superficial liver laceration, the silk thread is intermittently sutured, and the seam margin is 1cm. The needle should reach the base of the crack to prevent the dead space and form a hematoma or secondary infection. If there is incomplete or still bleeding, the omentum may be blocked and sutured. Severe liver contusion and laceration, especially when accompanied by large intravascular vascular injury or more tissue inactivation, often requires partial liver, liver segment, liver lobe or hepatic resection. If the condition is critical and cannot be tolerated, or if the condition is not allowed, the common hepatic artery (after the right gastric artery), the left and right hepatic artery, and even the hepatic artery may be ligated to achieve hemostasis; however, the hepatic necrosis is caused by the above ligation. The dangers also increase in turn. For patients who are still unable to stop bleeding and are very critical, a long gauze strip can be used to block the hemostasis and lead out from the other side of the abdominal wall. A hose should be placed under the liver for body position drainage.
