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.
ObjectiveTo study the indication and means in dissection lymph nodes of the No.10 and No.11 without splenectomy in radical gastrectomy for gastric cancer. MethodsAccording to the location, type of pathology, clinical and pathological classification, lymphatic drainage and spread of gastric carcinoma togather with the immunological function of spleen, selection of operative procedure without splenectomy should be considered, so the related literatures were reviewed. ResultsRetained spleen had been shown to improve 5year survival of patients with gastric cancer of stage Ⅰ,Ⅱ and Ⅲ,splenectomy had been shown to improve 5year survival of patients with gastric cancer of stage Ⅳ,whose carcinoma was infiltrating splenic and the lymph nodes of the No.10. The complications of different means of dissection of the lymph nodes made no difference.Conclusion Dissection of the lymph node without retained spleen or allogenic spleen transplantation is indicated for the patients with cancer of stage Ⅳ,whose spleen is invaded by the tumor.
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 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.
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.
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 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.
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.
Objective To approach the prognosis after liver transplantation （LT） of liver function for Child grade A in patients with portal hypertension， and to compare with periesophagogastric devascularization with splenectomy （PDS）. Methods The data of 195 portal hypertension cases with Child A caused by hepatitis B cirrhosis who received surgical treatment of PDS （152 cases） or LT （43 cases） in division of liver transplantation center of West China Hospital of Sichuan University from 1999 to 2011 were retrospectively analyzed. The pre-， intra-， and postoperative variables in two groups that including patients’ age， score of Child， score of model for end-stage liver disease （MELD）， total bilirubin （TB），creatinine （Cr）， international normalized ratio （INR）， albumin （Alb）， complications of portal hypertension， amount of intraoperative bleeding and blood transfusion， operative time， and in the ICU and hospital stay time were compared. The postoperative outcomes were statistically analyzed including severe postoperative complications， short-term and long-term survival rates. Results Compared with PDS group， the amount of intraoperative bleeding and blood transfusion of LT group were morer （P＜0.05）， the operative time， in the ICU and hospital stay time of LT group were longer （P＜0.05）. The rate of severe postoperative complications in LT group was higher than that in PDS group 〔18.60% （8/43） vs. 1.97% （3/152），P＜0.05〕. The levels of TB and Cr during the postoperative period in LT group were higher than that in PDS group （P＜0.05）. Although the INR on day 1 after operation in LT group was higher than that in PDS group （P＜0.01）， but the difference disappeared soon on day 7 after operation in two groups （P＞0.05）.The 1-， 3-， and 5-year survival rates of the LT and PDS groups were 90.3%， 86.5%， 86.5%， and 100%， 100%， 100%， respectively， significant difference were observed in both short-term and long-term survival rates between the two groups （P＜0.05）. Conclusion LT offered no significant survival benefit to patients with portal hypertension and Child A due to hepatitis B cirrhosis， whereas PDS could be an effective treatment.
