Restrictive portal vena shunting

1 for the treatment of intrahepatic portal hypertension, esophageal varices bleeding quiescent period with splenomegaly hypersplenism; 2 for intrahepatic portal hypertension, esophagogastric varices acute massive bleeding patients, short When the time is combined with non-surgical treatment, emergency surgery should be sought within 24 hours after hemorrhage. 3 For patients with recurrent esophagogastric varices bleeding who have undergone splenectomy and other operations, such as portal vein patency, no thrombosis can be implemented. The operation; 4 patients with liver function classification is ChildA or B. Treatment of diseases: portal hypertension, portal hypertension Indication 1 for the treatment of intrahepatic portal hypertension, esophageal varices bleeding quiescent period with splenomegaly hyperfunction; 2 For patients with intrahepatic portal hypertension and acute massive hemorrhage of esophagogastric varices, when short-term comprehensive non-surgical treatment is ineffective, emergency surgery should be sought within 24 hours after bleeding; 3 For patients with recurrent esophagogastric varices bleeding who have undergone splenectomy and other operations, such as portal vein patency, no thrombosis can also be performed this operation; 4 The patient's liver function classification is Child A or B. Surgical procedure The spleen is removed first after surgery, and then the small intestine is pushed to the lower abdomen to reveal the duodenal ligament and the small omentum hole. The common bile duct is recognized, the posterior peritoneum is cut, and the portal vein is found and separated. 3 weeks diameter, 4cm long. Then cut the lateral duodenum of the duodenum and separate it inward and downward to reveal the inferior vena cava. Separate 1/2 circumference and length 5 cm for anastomosis. In general, the side wall of the portal vein and the inferior vena cava were clamped by a three-winged blood vessel side wall clamp, and a 9 mm diameter shuttle hole was cut in the anterior wall of the two veins. The back wall is continuously valgus sutured with a 3-0 non-invasive needle nylon thread. The general needle spacing is about 1.5 mm, then the outer wall is sutured and the needle is reinforced at both corners. In order to avoid postoperative anastomosis, a plastic ring with a diameter of 1 cm can be placed in the anastomosis to limit the anastomosis.
