We had performed transjugular intrahepatic portosystemic stent shunt (TIPSS) in one hundred and three patients with advanced liver cirrhosis and portal hypertension from July,1993 to January, 1995. TIPSS was carried out successfully in ninty-eight out of 103 cases and the technical success rate was 95.2%. Acute variceal bleeding was immediatly controlled and portal pressure reduced by an average of 1.36±0.02 kPa after TIPSS. The disappearance of gastric cornoary and esophageal varices, the shrinkage of spleen and the reduction of ascite were observed . Three patients died of acute liver failure and one died of variceal redbleeding within 30 days of treatment. Mild encephalohthy was obserbed in 10 cases with TIPSS. At follow-up of 1～22 months, variceal rebleeding and ascite were observed in 6 patients and stenosis of shunt was evident is 12.5% of cases by the subsequent doppler sonography. According to this result, TIPSS is an effective method for the treatment of portal hypertension.
ObjectiveTo investigate the risk factors of postoperative portal vein thrombosis (PVT) after devascu-larization in patients with cirrhotic portal hypertension. MethodsThe clinical data of 40 patients with cirrhotic portal hypertension treated with splenectomy and gastric pericardial devascularization were retrospectively analyzed to investigate the related risk factors. ResultsA total of 12 of the 40 patients suffered from PVT (30.00%). The results of multivariate analysis showed that portal vein diameter, postoperative portal vein velocity, platelet count at 2 weeks postoperatively, and postoperative portal vein pressure were the factors influencing the incidence of PVT after devascularization. Patients with the greater portal vein diameter and platelet count at 2 weeks postoperatively, the lower postoperative portal vein velocity and postoperative portal vein pressure, had higher ratio of PVT (P < 0.05). ConclusionPortal vein diameter, portal vein blood flow velocity, platelet count, and postoperative portal vein pressure were the main risk factors for PVT after surgery in patients with cirrhotic portal hypertension.
ObjectiveTo evaluate clinical efficacy of the modified Sugiura procedure with cardia transection in treatment of recurrent portal hypertension with upper gastrointestinal bleeding. MethodsFrom January 2007 to January 2015, there were 28 cases of recurrent portal hypertension with upper gastrointestinal bleeding were treated by the modified Sugiura procedure with cardia transection in The Second People's Hospital of Yichang and The Zigui County People's Hospital, collecting the clinical data of them and then summarizing the therapeutic effect. ResultsAll cases underwent surgery successfully with no operative death. The operative time was 120-300 minutes with an average of 160 minutes. About surgical blood loss was 100-500 mL, with an average of 210 mL. Two cases suffered from postoperative gastrointestinal bleeding, 6 cases suffered from postoperative gastric dysfunction, and no one suffered from anastomotic leakage, anastomotic stenosis, and portal vein thrombosis. Three cases died in reason of liver failure and hepatic coma. There were 24 cases were followed up for 6-60 months, with the median of 33 months. No recurrence of gastrointestinal bleeding happened during the follow-up period. Sixteen cases underwent gastroscopy in 6 months after surgery, according to the results, the clinical effect was fine. For grade of varicose veinsm, there were 14 cases of grade GⅠ and 2 cases of grade GⅡ. For shape of varicose veins, there were 11 cases of grade F1 and 5 cases of grade F2. ConclusionThe modified Sugiura procedure with cardia transection is a safe and thorough operation for recurrent portal hypertension with bleeding.
OBJECTIVE The purpose of this study was to study the effect of splenopneumopexy for patients with portal hypertension in children. METHODS From March 1993 to April 1998, splenopneumopexy was performed on six children with portal hypertension. Doppler ultrasound and radionuclide were used to demonstrate the portopulmonary shunt after operation. RESULTS The bleeding from the esophageal varices was controlled and the esophageal varices were eliminated gradually. The symptoms pertaining to hypertension were disappeared. The patency of the shunt was maintained without the formation of thrombosis. No pulmonary complication was observed. CONCLUSION The results indicated that splenopneumopexy was a safe and effective procedure for patients with portal hypertension in children.
Anatomical venous distribution around the lower esophagus, gastric cardia and fundus in 100 adult cadavers had been observed. The results showed that the occurrence rate of the left gastric and the right gastric veins were 96% and 92% respectively. Venous distribution in the lesser curvature of the stomach can be classified into five types: the left gastric vein type, the right gastric vein type,the left gastric vein dominant type, the right gastric vein dominant type, and the balance type (of the left and the right gastric veins). The retrogastric veins were found in 73.6% of 100 cadavers showed portacaval anastomoses. From March 1976 to March 1992, we had treated with transthoracic interruption of portoazygous circulation, 52 cases of portal hypertension resulting in bleeding du to rupture of esophageal and venriculi fundus varices ( male 43, female 9). Among the 41 emergency operations, 2 cases died (4.9%), and bleedings were controlled by emergency surgery in 92.6% of cases. 44 of the 50 cases (88%) were followed up. The recurrence of bleeding occured in 5 cases, with a long-term bleeding rate of 11.4%. The authors suggest that anatomical factors might be the reason of inadequacy of portaoazygous interruption, and claim the advantages of transthoracic interruption of portoazygous circulation.
ObjectiveTo analyze risk factors of rebleeding after laparoscopic selective pericardial devascularization combined with splenectomy.MethodsThe clinical data of 147 cases of portal hypertension treated by the laparoscopic selective devascularization combined with splenectomy from February 2014 to September 2018 were retrospectively analyzed. The univariate analysis was used to find the difference between the rebleeding group (n=20) and the non-bleeding group (n=127), then the multivariate logistic regression analysis was selected for screening out the most closely related risk factors for the rebleeding.ResultsThe rebleeding occurred in 20 of 147 patients (13.6%). There were differences in the platelet count, prothrombin time, serum albumin, diameter of main portal vein, classification of liver function, ascites, hepatic encephalopathy, and portal hypertensive gastropathy between the rebleeding group and the non-bleeding group (P<0.050). The classification of liver function ［OR=3.444, 95% CI (1.211. 9.793）, P=0.020］, ascites ［OR=2.859, 95% CI (1.069, 7.645), P=0.036］, hepatic encephalopathy ［OR=4.265, 95% CI（1.121, 16.230）, P=0.033］, and portal hypertensive gastropathy ［OR=6.744, 95% CI (1.675, 27.156), P=0.007］, and platelet count ［OR=4.744, 95% CI (1.073, 20.969), P=0.040］ were the independent factors for the postoperative rebleeding by the logistic regression analysis.ConclusionFor patients with risk factors of rebleeding, preoperative treatment should be actively taken and postoperative prevention of rebleeding should be highly vigilant.
