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.
门静脉高压症是慢性肝病的主要合并症之一，它所导致的食管胃底静脉曲张破裂出血死亡率可达30%～50%，是肝硬变患者的主要死亡原因。1概述自1945年Whipple等人倡导门体分流手术治疗门静脉高压症以来，各国学者作出了不懈努力，探求对这种顽症的治疗手段。最近20～30年在治疗方法上出现了许多革新，如内窥镜下曲张静脉硬化剂注射、曲张静脉套扎、门体静脉选择性分流（远端脾肾分流）等。应用β受体阻滞剂心得安来预防或治疗门静脉高压症引起的上消化道出血取得了肯定的疗效。小口径人工血管门静脉下腔静脉搭桥分流减少了门体分流手术后脑病的发生率，而复发出血率几乎可与传统门腔分流术相比。经颈内静脉肝内门体分流术（TIPSS）治疗急性上消化道出血的疗效十分肯定，尤其适用于手术风险大、肝功能差者。肝脏移植作为治疗终末期不可逆性肝病的成熟手段，近年来也越来越多地应用于肝硬变门静脉高压症的治疗，与其它各种治疗手段相比，肝移植可算是对门静脉高压症治疗的一种革命性的变化，一个成功的肝移植一劳永逸地解决了门静脉高压症产生的根源，使门静脉高压症得到根治。
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.
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．
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.
Objective To investigate the effect of vitamin K1 in the function of blood coagulation state, intraopera- tive blood loss, and hemoglobin content of liquid in postoperative drainage in patients with cirrhosis combined with portal hypertension before and after splenectomy combined with the hydrodynamic vein cut-out surgery. Methods In total of 143 cases of cirrhosis combined with portal hypertension who treated in our hospital from January 2010 to October 2015 were prospectively collected, and randomly divided into 3 group, including 51 cases of vitamin K1 group, 45 cases of carbazochrome sodium sulfonate group, and 47 cases of control group. Drug was used form 1 week before surgery to 5 days after surgery (vitamin K1 group: vitamin K1, 0.03 g, intravenous drip; card collaterals sodium sulfonic group: card collaterals sulfonic sodium, 80 mg, intravenous drip; control group: normal saline, 250 mL, intravenous drip). Prothrombin time of patients in 3 groups was detected at 1 week before surgery, 3 days before surgery, 1 day before surgery, 1 day after surgery, 3 days after surgery, and 5 days after surgery; hemoglobin content of liquid in postoperative drainage was detected on 1, 3, and 5 days after surgery. Results In terms of prothrombin time, there was no significant difference at 1 week before surgery and 5 days after surgery (P>0.05); prothrombin time of vitamin K1 group was lower than those of carbazochrome sodium sulfonate group and control group on 3 days and 1 day before surgery (P＜0.05), but there was no significant difference between carbazochrome sodium sulfonate group and control group on 3 days and 1 day before surgery (P>0.05); prothrombin time of vitamin K1 group and carbazochrome sodium sulfonate group was both lower than that of control group on 1 day and 3 days after surgery (P＜0.05), but there was no significant difference between carbazochrome sodium sulfonate group and vitamin K1 group on 1 day and 3 days after surgery (P>0.05). In terms of intraoperative blood loss, intraoperative blood loss of vitamin K1 group was lower than those of carbazochrome sodium sulfonate group and control group (P＜0.05), but there was no significant difference between carbazochrome sodium sulfonate group and control group (P>0.05). In terms of hemoglobin content of liquid in postoperative drainage, it was lower in vitamin K1 group and carbazochrome sodium sulfonate group than that of control group on 1 day and 3 days after surgery (P＜0.05), but there was no significant difference among 3 groups on 5 days after surgery (P>0.05). Conclusion Vitamin K1 is helpful to improve function state of blood coagulation before and after surgery in patients with cirrhosis combined with portal hypertension (from 1 week before surgery to 3 days after surgery), and reduce the intraoperative blood loss; carbazochrome sodium sulfonate can improve function status of postoperative blood coagulation to 3 days after surgery and postoperative blood loss, but has no obvious improvement in the function status of preoperative blood coagulation and introperative blood loss.
Surgerical treatment has been used for portal hypertension over a hundred years, and has evolved from various portosystemic shunts to devascularizations and selective shunts. Selective shunting, which has the advantages of long-term prevention from recurrent variceal bleeding and maintenance of hepatic portal vein perfusion, has developed from single distal splenorenal shunt to various procedures including distal splenocaval shunt, coronary caval shunt, coronary renal shunt, etc. Selective shunting can also be achieved after reconstruction of spontaneous portosystemic shunt. Preoperative portal venous system CT angiography, intraoperative ultrasound Doppler and portal vein pressure measurements may provide patients with a more reasonable treatment of choice.
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.
