42 Wistar rats were divided into three groups at random, liver cirrhosis (LC), portal vein stricture (PVS) and sham operation (SO) group. The changes of barrier capability of gastric mucosa in portal hypertensive rats were observed. The results demonstrated: the splanchnic blood flow of the portal hypertensive rats increased, as compared with the normal control group (Ｐ＜0.001), but actually gastric mucosa was under the condition of ischemia. Mucosa of gastric wall glycoprotein and PGE2 of gastric mucosa decreased, as compared with the normal control (Ｐ＜0.01); and more seriously decreased in cirrhotic portal hypertensive rats, there was no significant difference about amount of the basal acid secretion (BAS) among the three groups, but the amount of H＋ backdiffusion (H＋BD) was obviously increased, as compared with the normal control group (Ｐ＜0.001). The amount of H＋BD of cirrhotic portal hypertensive rats was the highest among this three groups. The results suggest that the barrier capability of gastric mucosa with portal hypertension is lower than that of the normal control group and much lower with cirrhotic portal hypertensive rats. The portal hypertensive gastropathy is associated with the lower capability of defense of gastric mucosa. The condition of liver function contributes to the change of barrier capability of gastric mucosa.
Objective To explore the methods， clinical effects， and application value of laparoscopic splenectomy combined with pericardial devascularization. Methods The clinical data of 23 patients with liver cirrhosis and portal hypertension who performed laparoscopic splenectomy combined with pericardial devascularization between july 2009 and july 2012 in our hospital were analyzed retrospectivly. Results In 23 cases， 2 cases were converted laparotomy due to bleeding， 21 cases were successfully performed laparoscopic splenectomy combined with pericardial devascularization. The operative time was 230-380 minutes （average 290 minutes）. The intraoperative blood loss was 300-1 500 mL （average 620 mL）. The postoperative fasting time was 1-3 days （average 2 days）. The postoperative hospital stay was 8-14 days （average 10 days）. Conclusion Laparoscopic splenectomy combined with pericardial devascularization is a feasible， effective， and safe procedure as well as minimally invasive hence is applicable for patients with portal hypertension and hypersplenism．
ObjectiveTo evaluate long-term therapeutic effect of esophagogastric devascularization without splenectomy in treatment of portal hypertension with esophagogastric varices hemorrhage. MethodsThe patients who took esophagogastric devascularization without splenectomy from 2008 to 2013 were followed-up in clinic or through phone. The remission of esophagogastric varices, rebleeding, survival and long-term postoperative complications were observed. ResultsA total of 32 patients were taken esophagogastric devascularization without splenectomy in Peking University People's Hospital from 2008 to 2013. One patient died during the perioperative period. Twenty-three patients were followed-up for 10-81 months with an average 45.5 months, of whom 7 patients had rebleeding, 5 patients died, 3 patients had new onset portal vein thrombosis, 2 patients had esophageal anastomotic strictures. ConclusionEsophagogastric devascularization without splenectomy is an effective method in treatment of portal hypertension with esophagogastric varices hemorrhage in selected patients.
目的 交流断流术加脾肾分流术联合治疗门静脉高压症的体会。方法 对我院1994～2000年采用断流术加脾肾分流术联合治疗的12例门静脉高压症患者资料进行回顾性总结与分析。结果 全组病例均获随访，除1例在术后15个月因肝癌死亡外，其余11例均健在，其中10例生活质量良好，并恢复原来工作，生存时间最短15个月，最长8年，中位生存时间4年。术后均无出血和肝性脑病发生。结论 应用联合术治疗门静脉高压症避免了单一断流术、分流术及脾切除术的缺点，具有术后再出血率低，患者生存质量高及远期生存率高等优点，是一种理想的术式。
Transjugular intrahepatic portosystemic shunt (TIPS) has been used in the treatment of cirrhotic portal hypertension for more than 30 years. With the development of stent technology and clinical practice technology, TIPS is becoming more and more perfect in the treatment of portal hypertension. From the single-use of bare stent in the past to the application of bare stent combined with coated stent or particular Viatorr stent, the patency of stent has been significantly improved. In addition, the selection of stent caliber and the puncture part of shunt gradually reduces the occurrence of hepatic encephalopathy, liver failure and other complications caused by excessive shunt. TIPS technology has the advantages of minimally invasive, safe and reducing portal vein pressure. It has gradually become one of the primary surgical methods in the treatment of portal hypertension, esophagogastric variceal bleeding, intractable ascites, and so on.
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.
目的 探讨肝外型门静脉高压分流术人工血管闭塞后血流重建的诊治方法。方法 对2006年3月至2010年12月期间笔者收治的102例肝外型门静脉高压患者进行了开放手术治疗，其中3例是再次手术患者并对已严重狭窄或闭塞的人工血管进行了血流重建。结果 3例患者人工血管均得以血流重建，分别随访了32、17及30个月，患者均已恢复正常生活。结论 合适的病例选择、合理的手术方案以及术中和术后规范的抗凝治疗是保证门静脉高压分流术后人工血管长期通畅的重要因素。
Objective To investigate the clinical feature and misdiagnosis of 128 patients with Wilson’s disease and proposed the points of diagnosis for this disease. MethodsOne hundred and twenty eight patients with Wilson’s disease from Jan. 1983 to Apr. 2000 of our hospital were reviewed. Their clinical feature and diagnosis condition, such as the first onset symptoms, misdiagnosis conditions and hypersplenism were studied. Results①The first onset symptoms: 64 showed liver dysfunction and 52 presented manifestation of central nerves system (CNS) (Pgt;0.05). ②The age of liver dysfunction was significantly younger (13 years) than that of CNS involved patients (23 years, P＜0.05). ③Patients with the liver damage had enlarged liver (3 cm below the right rib) and hypersplenism and 12 patients had to receive splenectomy. ④Gastroscopy or barium meal showed that esophageal varicose rate was 30.8%（12/39） and 7 patients had large upper gastrointestinal bleeding. Conclusion The age of liver involved patients is significantly younger than that of the CNS involved patients. The liver cirrhosis, hypersplenism and portal hypertension are very common complications of Wilson’s disease and some prevention and cure measures should be taken for these complications.
