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.
ObjectiveTo summarize the recent development of surgical treatment for portal hypertension with hypersplenism. MethodsThe related literatures on various operation treatment of hypertension with hypersplenism at home and abroad in recent years were collected and reviewed. ResultsThere are many operation treatment methods of hypertension with hypersplenism, includes the pericardial devascularization, subtotal splenectomy, partial splenic embolization, spleen radiofrequency ablation, splenic artery ligation, distal splenorenal shunt, and so on. The different operation methods each has its advantages and disadvantages, but there are a certain percentage of the incidence of complications. At the same time, due to the limited understanding of the function of the spleen in portal hypertension, the treatment of "resecting" or "reserving" spleen has always been the hot spot of the academic dispute. ConclusionFor what kind of operation method is the most suitable for the treatment of hypertension with hypersplenism is no fixed conclusion.

Twenty-four patients were followed up for an average of 27 months （8-57 months）. The overal survival rate was 92.6% （25/27）. Conclusion Selective paraesophagogastric devascularization without splenectomy is an effective method for treatment of portal hypertension with upper gastrointestinal hemorrhage.
ObjectiveTo analyze the effect and incidence rate of major postoperative complications of pericardial devascularization in treatment of portal hypertension. MethodsEnglish and Chinese literatures about pericardial deva-scularization in treatment of portal hypertension were searched through Medline, Elsevier, PubMed, CNKI, and WanFang database, and meta analysis was taken in the process by using R-2.15 software. ResultsIn total of 671 literatures were searched and 23 were selected finally according to inclusion criteria and exclusion criteria.The results of meta analysis showed that, the effect of pericardial devascularization in treatment of portal hypertension were as follows:the incidence rate of rebleeding was 21%(95% CI: 0.18-0.24), the incidence rate of hepatic encephalopathy was 4%(95% CI: 0.02-0.06), the incidence rate of ascites was 29%(95% CI: 0.14-0.47), mortality of operation was 3%(95% CI: 0.02-0.04), mortality was 23%(95% CI: 0.15-0.33). ConclusionsThere is a certain incidence rate of complications of pericardial devascularization, of which the most common complication is rebleeding.So, it is necessary to do further improvement and development of pericardial devascularization.
ObjectiveTo investigate impact of splenectomy plus pericardial devascularization on liver hemodynamics and liver function for liver cirrhosis patients with portal hypertension. MethodsThe internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of portal vein and hepatic artery of 42 cases of liver cirrhosis with portal hypertension were measured by Doppler ultrasonic instrument on day 1 before operation and on day 7 after operation. The free portal pressures at different phases (after open abdomen, after splenic artery ligation, after splenectomy, and after devasculanrization) were read from the disposable pressure sensor. Twenty-four healthy people through physical examination were selected as control. Results① The free portal pressure of liver cirrhosis patients with portal hypertension was decreased from (29.12±1.40) mm Hg after open abdomen to (22.71±1.21) mm Hg after splenic artery ligation, and further decreased to (21.32±1.12) mm Hg after splenectomy, but increased to (22.42±1.15) mm Hg after devasculanrization, the difference was statisticly different (all P < 0.01). ② Compared with the healthy people, for the liver cirrhosis patients with portal hypertension, the internal diameter, maximum velocity, minimum velocity, and flow volume of portal vein were significantly enlarged (all P < 0.01), which of hepatic artery were significantly reduced (all P < 0.01) on day 1 before operation; On day 7 after operation, the internal diameter of portal vein was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, and mean velocity of portal vein were significantly enlarged (all P < 0.01), but the internal diameter of hepatic artery was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01). For the liver cirrhosis patients with portal hypertension, compared with the values on day 1 before operation, the internal diameter and the flow volume of portal vein were significantly reduced (all P < 0.01) on day 7 after operation; the internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01) on day 7 after operation. ③ The Child-Pugh classification of liver function between before and after surgery had no significant difference (χ2=1.050, P > 0.05). ④ No death and no hepatic encephalopathy occurred, no thrombosis of splenic vein or portal vein was observed on day 7 after surgery. Conclusionsplenectomy plus pericardial devascularization could decrease portal vein pressure and reduce blood flow of portal vein, while increase blood flow of hepatic artery, it doesn't affect liver function.
