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 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 compare the difference of the changes of platelet counts after splenectomy between the patients with splenic rupture and patients with cirrhosis and portal hypertension, and to analyze the possible reasons and clinical significance. Methods The platelet count of 47 splenic rupture patients and 36 cirrhosis patients who had been carried out splenectomy from July 2008 to December 2009 in our hospital were counted, and the differences in platelet count and it’s change tendency of two groups were compared. Results In the splenic rupture group，the platelet count of all 47 patients increased abnormally after operation, the maxlmum value of platelet count among 300×109/L-600×109/L in 6 cases，600×109/L-900×109/L in 21 cases，and above 900×109/L in 20 cases. In the cirrhosis group，the maxlmum value of platelet count after operation was above 300×109/L in 26 cases，100×109/L-300×109/L in 8 cases，and below 100×109/L in 2 cases. The difference of maxlmum value of platelet count in the two groups had statistic significance（P=0.00）. Compared with the cirrhosis group, the platelet count increased more significant and decreased more slow in splenic rupture group（P＜0.05）.The abnormal days and rising range of platelet count were higher in patient with Child A than Child B and C（P=0.006，P=0.002）. Conclusions The change of platelet count after operation in splenic rupture group was obviously different from cirrhosis group because of the difference of the liver function and body situation of patients. To patients with splenic rupture or cirrhosis, appropriate treatment based on the platelet count and liver function could obtain good therapeutic effect.
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.
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.
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.
【Abstract】Objective To explore the effect and indication of splenectomy in liver transplantation. Methods From January 2001 to April 2006, 260 patients underwent piggyback orthotopic liver transplantation (PBOLT), and 28 patients had undergone combined PBOLT and splenectomy (splenectomy group). These patients were compared to 56 randomly selected non-splenectomy patients from the same transplant period, meaningly two controls were selected for every non-splenectomy case. Two groups were analyzed with respect to rate of infection and survival rate, as well as biopsy-proven acute allograft rejection within 30 days after transplantation. Results Rate of infection in the splenectomy group was higher than that in the non-splenectomy patients (85.7% vs 55.4%, P＜0.05). Acute rejection and survival rates in the splenectomy group were lower than those in the non-splenectomy patients (3.6% vs 14.3%, P＜0.05; 46.4% vs 82.1%, P＜0.05). Conclusion Concomitant splenectomy with PBOLT has a significantly higher patient mortality rate; it is mainly due to its septic complications. At present, unless there is a certain indication for splenectomy, this procedure is not recommended.
Objective To investigate the reasonable indication of splenectomy in radical resection for advanced proximal gastric cancer (APGC). Methods Fifty patients with APGC were studied and classified into total gastrectomy with splenectomy (TGS) group (n=18) and total gastrectomy without splenectomy (TG) group (n=32). The operation time, hospitalized duration, complications, and lymphe node metastasis at the spleen hilus were compared between two groups. Results The operation time, hospitalized duration and subphrenic infection rate in the TGS group were significantly higher than those in the TG group (Plt;0.05). The rate of lymph node metasitasis of No.10 and No.11 in the TG group was not different from that in TGS group (Pgt;0.05). Conclusion Direct spleen and its vessel invasion are the reasonable indication of splenectomy in radical resection for APGC.
Objective To investigate the effects of hand assistant laporoscopic splenectomy plus pericardial devascularization on systemic stress responses. Methods Forty patients with cirrhotic portal hypertension were selected， 20 cases of which were underwent hand assistant laparoscopic splenectomy plus pericardial devascularization (LAP group)， and the other 20 were underwent open splenectomy plus pericardial devascularization (OP group). The levels of blood glucose （BG）, insulin (Ins), triiodothyronine （T3）, tetraiodothyronine （T4）, corticosteroid （CS） and other related clinical data were measured before operation and on day 1-3 after operation, which were compared between two groups. Results There was no statistical significance between two groups on those levels before operation. On day 1 after operation， BG and CS level in both two groups were higher than those before operation (P＜0.05), but they were recovered on day 2 after operation in LAP group (Pgt;0.05), and on day 3 after operation in OP group (Pgt;0.05). BG and CS level in OP group were markedly higher than those in LAP group on day 2 after operation (P＜0.05). On day 1 after operation， Ins, T3 and T4 level of two groups were lower than those before operation (P＜0.05), but they were recovered on day 2 after operation in LAP group (Pgt;0.05) and on day 3 after operation in OP group (Pgt;0.05). Ins, T3 and T4 level in OP group were lower than those in LAP group on day 2 after operation (P＜0.05). There was no significant difference in operation time between two groups (Pgt;0.05). But laparoscopic surgery had more advantages than conventional open surgery such as reducing bleeding quantity in operation, shortening recovery time of bowel and urinary bladder function and the length of stay. Conclusion Compared with laparotomy, the laparoscope not only imposes less impact on physical stress system, but also makes recovery after operation more quickly.
Objective To explore and summarize the curative effect and experience of emergency devascularization for treatment of upper gastrointestinal bleeding due to portal hypertension. Melthods The clinical data of 42 patients with upper gastrointestinal bleeding due to portal hypertension， undergoing emergency devascularization from March 2006 to July 2011 in Shengjing Hospital of China Medical University were retrospectively analyzed. Results Of the 42 cases， 29 patients underwent emergency splenectomy plus esophagogastric devascularization， 8 patients underwent emergency spleen artery ligation plus esophagogastric devascularization， and 5 patients only underwent emergency esophagogastric devascularization. The hemostasis rate at 3 hours after emergent disconnection operation was 100%. One patient died of liver failure on 8 days after operation. Three patients supervened with hemorrhage in abdominal cavity on 2 days after operation， and succeeded in hemostasis by conservative treatment. Other patients were successfullydischarged from hospital after postoperative rehabilitation for 2-4 weeks. All cases were followed up regular in 1 year after operation， 5 patients were lost to follow-up. Among the 36 cases followed up， rehaemorrhagia occurred in 1 patientin 8 months after operation， cured by endoscopic variceal ligation subsequently. A primary liver cancer occurred in 1 patient during physical examination in 7 months after operation， followed by partial hepatectomy. Other patients could complete daily life and work. Conclusions The patients suffering from upper gastrointestinal bleeding due to portal hypertension are likely to benefit from appropriate operations. Decisive emergency devascularization can stop the bleeding rapidly and effectively， and save the lives of those patients.
