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．
【Abstract】ObjectiveTo explore the appropriate surgical management of the primary hepatocellular carcinoma with hypersplenism. MethodsOf 67 patients who has primary hepatocellular carcinoma with hypersplenism, 17 cases had hepatectomy combined with splenectomy, 7 cases had hepatectomy only, and the other 43 patients were treated with hepatic artery embolization and splenic artery embolization. ResultsThe symptoms of hypersplenism disappeared and the hemogram became normal 30 d after operation in 17 patients who had hepatectomy combined with splenectomy, but worsened in 7 patients who only had simple hepatectomy and 6 cases of those patients were treated with splenic artery embolization 3-7 months after operation. In 43 patients treated with hepatic artery embolization and splenic artery embolization, 79%（34/43）had improved hypersplenism symptoms and the hemogram became normal. ConclusionThe treatment of primary hepatocellular carcinoma with hypersplenism should be strived for hepatectomy combined with splenectomy. If the liver mass cannot be resected, hepatic artery embolization and splenic artery embolization should be chosen.
Objective To defect the level of platelet antibody-IgG (PA-IgG) in patients with congestive splenomegaly and hypersplenism and the change of PA-IgG level after splenectomy and subtotal splenectomy. Methods Twenty four cases of congestive splenomegaly and hypersplenism were investigated. Results The level of PA-IgG in 24 cases were higher than normal range (Ｐ＜0.01), while the platelet count were lower than normal range and there was a significant negative correlation between the level of PA-IgG and platelet count (r＝-0.4747, Ｐ＜0.05). After subtotal splenectomy or splenectomy, the level of PA-IgG descended, the platelet count raised and the negative correlation between the level of PA-IgG and platelet count disappeared. Conclusion The results suggest that there is a immunoregulation between PA-IgG and platelet. Perhaps spleen has some relation with the immunoregulation.
Objective To study the effect of splenectomy on the anti-tumor immunity in rats with induced hepatocellular carcinoma (HCC). Methods At the second and fourth month of the induced HCC, the NK cell activity, TNF-α level and total lymphcyte in blood were measured in the group of splenectomy and the control group. Results There were no different in the total lymphcyte and TNF-α in the blood in two groups, but there were significant difference in the NK cell activity between the group of splenectomy and the control group (Ｐ＜0.05). Conclusion There are some change in the anti-tumor immunity after splenectomy in rats, in which NK cell activity is at low level continuously. TNF-α isn′t affected after the second month after splenectomy.
Objective To explore the cause, diagnosis, and treatment methods of portal vein thrombosis （PVT） after splenectomy. Methods The clinical data of 29 patients who were got splenectomy because of portal hypertension or traumatic splenic rupture from August 2002 to August 2008 in our hospital were analyzed retrospectively. Results Tweenty-seven patients with PVT were treated successfully, whose thrombi were absorbed completely or partially. One case died of peritonitis，septic shock，and multiple organ failure. One case died of hematemesis, hepatic coma，and multiple organ failure. Tweenty-four patients were followed up, the follow-up time was 0.5 to 3 years, the average was 2 years. Two cases died of massive hemorrhage, 1 case died of hepatic encephalopathy，and 1 case died of liver failure. Two cases occurred deep venous thrombosis in one year after treatment, and the remaining patients had no recurrence of venous thrombosis. Conclusions PVT have some connection with the raise of blood platelet and the hemodynamic changes of the portal vein system after splenectomy. Standardization of operation, early diagnosis, early line anticoagulant，and antiplatelet adhesion therapy are effective way to prevent and treat PVT.
目的 探讨腹腔镜下脾切除术（LS）治疗特发性血小板减少性紫癜(ITP)的临床效果。方法 我院2003年1月至2008年8月期间行LS治疗ITP患者20例，将术前与术后1、2、7、14、30、90及180 d的血小板计数进行比较。结果 20例ITP患者均顺利完成LS，平均手术时间为156 min，术中出血平均50 ml，平均住院时间为9 d。完全停用药物14例； 4例患者术后需继续服用激素治疗，但激素用量较前明显减少； 无效2例。总有效率为90%。术后1、2、7、14、30、90及180 d的血小板数量分别为(251.6±91.4)×109/L、(312.6±90.1)×109/L、(343.2±103.7)×109/L、(300.0±98.2)×109/L、(175.6±42.6)×109/L、(151.8±42.1)×109/L及(207.0±53.4)×109/L,分别与术前〔(38.3±19.4)×109/L〕比较，经t检验，差异均有统计学意义（P＜0.001）。结论 LS治疗ITP是可行和安全的，手术效果满意。
ObjectiveTo study the results of splenectomy in patients with idiopathic thrombocytopenic purpura. MethodsSeven patients who failed to respond to conservative management were treated with splenectomy and followed up for 6 months to 8 years (1990～1999).ResultsThe presplenectomy patients had symptoms of bleeding and their platelet count on average was 32×109/L. The 3th,7th day and 1th,2th, 6th month after splenectomy, the average platelet count was 191×109/L,354×109/L,317×109/L,200×109/L and 151×109/L respectively. Their platelet recovered to normal during a week in 7 cases (≥100×109/L); In 6 patients the platelet count was normal in the 6th month after splenectomy, the success rate was 6/7, the rate of remission was 1/6. The platelet count after splenectomy was significantly higher than that before splenectomy.ConclusionThere are no correlation between the course of disease before splenectomy and the results of splenectomy. Splenectomy is safe and effective in the treatment of idiopathic thrombocytopenic purpura.
