Objective To analyze the effect of monitoring and modulating the portal vein pressure and blood flow during living donor liver transplantation （LDLT） on preventing small-for-size-syndrome (SFSS). Methods Data of forty-four LDLT recipients between Oct.2007 and Oct.2008 were reviewed. Actual graft-to-recipient weight ratio（GRWR）, portal vein flow and pressure during operation and syndrome of SFSS after operation were recorded. The patients received splenectomy or splenic artery ligation according to actual GRWR, portal vein flow and pressure and WBC. Relationships between patients’ GRWR, portal vein flow, portal vein pressure and occurrence of SFSS were analyzed. Results Six patients received splenectomy and 7 patients received splenic artery ligation to decrease the portal vein flow and pressure during the operation. The portal vein flow and pressure decreased after splenectomy （Plt;0.05）. The portal vein pressure decreased （Plt;0.05） and the portal vein flow had no significant change after splenic artery ligation （P＞0.05）. No SFSS occurred after operation. Conclusion Modulation of portal vein flow and pressure by splenectomy or splenic artery ligation during LDLT operation can decrease the portal vein flow and pressure, and which can prevent the incidence of SFSS.
ObjectiveTo explore perioperative management model of ABO-incompatible liver transplantation. MethodsThe clinical data of ABO-incompatible caderveric liver transplantions without urgency performed in our center from July 2006 to May 2010 were analyzed retrospectively. Four patients had received an ABO-incompatible graft: AB to O in three, AB to A in one. All the cases were diagnosed as end-stage liver disese, one of them was primary hepatocellular carcinoma. ResultsFour survived to now （11 to 19 months） without severe infections and acute rejections. Two experienced coagulative disturbance and one of them had a second exploration. One developed acute renal failure and recovered with help under continuous veno-venous hemofiltration. All the cases were given 20 mg basiliximab two hours before revascularization and on day 4 after operation respectively. Splenectomy was performed in three, intravenous immunoglobulin was given in all more than seven days. Isohemagglutinin titers were basically stable and not relevant to the clinical manifestations. Antibiotic prophylaxis and immunosuppression protocol was same as the ABO compatible transplants except a 3-month-delay for steroid withdrawal. ConclusionABO-incompatible liver transplantation could be performed with appropriate perioperative management, such as basiliximab induction, splenectomy, intravenous immunoglobulin administration, and routine immunosuppression.
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.
Objective To discuss the therapeutic effectiveness of surgical approach to complex intrahepatolithiasis with biliary liver cirrhosis.Methods A case of complex intrahepatolithiasis with biliary liver cirrohosis, portal hypertension was treated with splenectomy and pericardial devascularization plus left hepatectomy and portal cholangio plasty with T tube drainage. Results Follow up one year and a half after operation, no symptom of cholangitis was found, and there is no relapse up to date. Conclusion Combined operation of hepatectomy with splenectomy is an ideal and effective treatment for complex intrahepatolithiasis with biliary liver cirrhosis.
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 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 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.
ObjectiveTo investigate the predictive factors of portal vein thrombosis (PVT) before and after splenectomy and gastroesophageal devascularization for liver cirrhosis with portal hypertension. MethodsSixty-one cases of liver cirrhosis with portal hypertension who underwent splenectomy and gastroesophageal devascularization were enrolled retrospectively. The patients were divided into PVT group and non-PVT group based on the presence or absence of postoperative PVT on day 7. The clinical factors related with PVT were analyzed. ResultsThere were 25 cases in the DVT group and 36 cases in the non-DVT group. The results of univariate analysis showed that the preoperative platelet (P=0.006), activated partial thromboplastin time (P=0.048), prothrombin time (P=0.028), and international normalized ratio (P=0.029), postoperative fibrin degradation product (P=0.002) and D-dimer (P=0.014) on day 1, portal venous diameter (P=0.050) had significant differences between the DVT group and non-DVT group. The results of logistic multivariate regression analysis showed that the preoperative platelet (OR=0.966, 95% CI 0.934-1.000, P=0.048) and postoperative fibrin degradation product on day 1(OR=1.055, 95% CI 1.011-1.103, P=0.017) were correlated with the PVT. The PVT might happen when preoperative platelet was less than 34.5×109/L (sensitibity 80.6%, specificity 60.0%) or postoperative fibrin degradation product on day 1 was more than 64.75 mg/L (sensitibity 48.0%, specificity 91.7%). ConclusionPreoperative platelet and postoperative fibrin degradation product on day 1 might predict PVT after splenectomy and gastroesophageal devascularization for liver cirrhosis with portal hypertension.
ObjectiveTo explore the effect of partial splenic embolization on splenectomy plus devascularization of esophageal and gastric vein. MethodsTwenty three cirrhosis patients with portal hypertension combined the hypersplenism (partial splenic embolization group), who received partial splenic embolization in our hospital from June 2010 to June 2015, as well as 30 cirrhosis patients with portal hypertension combined the hypersplenism without undergoing partial splenic embolization in the same period (non-partial splenic embolization group), were collected retrospectively. All patients underwent splenectomy plus devascularization of esophageal and gastric vein. Comparison of operation time, intraoperative blood loss, intraoperative blood transfusion volume, postoperative total flow of abdominal drainage tube, postoperative gastrointestinal function recovery time, hospital stay, and the incidence of complication was performed. ResultsThe operation time[(3.56±0.70) h vs. (1.78±0.28) h], intraoperative blood loss (900 mL vs. 250 mL), intraoperative blood transfusion volume (800 mL vs. 200 mL), postoperative total flow of abdominal drainage tube (450 mL vs. 150 mL), postoperative gastrointestinal function recovery time[(43.38±18.68) h vs. (27.60±12.39) h], hospital stay (12 d vs. 7 d), and incidence of incision infection[34.8% (8/23) vs. 10.0% (3/30)] of partial splenic embolization group were all higher or longer than those corresponding indexes of non-partial splenic embolization group (P < 0.05). All patients of 2 groups were followed up by telephone visit for 6-58 months, and the median was 28-month. There was no recurrence of gastrointestinal hemorrhage during the follow-up period. ConclusionsSplenectomy is more difficult, and maybe has more intraoperative blood loss and complications for cirrhosis patients with portal hypertension combined the hypersplenism, who received partial splenic embolization ever. For these patents, the recovery time is longer. We should make choice of partial splenic embolization or splenectomy directly according to the patients' situation, to implement individualized treatment, so we can make the biggest benefit for patients.
ObjectiveTo investigate the experience in the treatment of splnic malignant tumors with laparoscopy. MethodsThe clinical data of 51 patients with splnic malignant tumor who underwent splenectomy between January 2009 and July 2015 were retrospectively reviewed. Patients were divided into two groups based on the surgical method: Open splenectomy (OS group, n=18) and laparoscopic splenectomy (LS group, n=33). The preoperative, intraoperative and postoperative data of the patients were collected and analysed, the differences of each index during perioperative period (general information), intraoperative data (operative time, estimated blood loss, the size of spleen, intraoperaive transfusion) and postoprative situation (hospital stays, the first oral intake, postoperative pancreatic fistula, rehaemorrhagia, abdominal infection or pulmonary infection and the like) were compared. ResultsLS group compared with OS group, the operative time of LS group was significantly shorter than that of OS group [(103.64±16.92) min vs. (144.44±31.10) min, P=0.000〕, the amount of bleeding of LS group [M (Q25, Q75): 60 (50, 100)〕was significantly less than the OS group [M (Q25, Q75): 150 (115, 210)〕, P=0.000. The hospitalization time of LS group was significantly shorter than the OS group [(13.61±9.91) d vs. (9.03±3.09) d, P=0.017〕, and the LS group has a lower indication of the postoprative complications of fever and pulmonary infection (P=0.010 and P=0.003). Conciusions Laparoscopic splenectomy is feasible in the treatment of splenic malignant tumors, the employment of laparoscopy can shorten the operative time, has the advantages of less bleeding, the shorten hospital stays, lower indication of postoprative complications, and being worthy of further popularization and application.
