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.
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 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 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 investigate clinical application value of totally laparoscopic splenectomy via anterior approach. MethodsThe clinical data of 26 consecutive patients underwent totally laparoscopic splenectomy via anterior approach from March 2012 to June 2015 in this hospital were analyzed retrospectively. There were 11 males and 15 females. These patients included 2 cases of traumatic spleen ruptures, 4 cases of idiopathic thrombocytopenic purpuras, 1 case of hereditary spherocytosis, 3 cases of splenic cysts, 5 cases of autoimmunity hemolytic anemias, 2 cases of splenic hemangioma, 1 case of hematolymphangioma, 8 cases of cirrhosis portal hypertensions. The operative time, intraoperative bleeding, postoperative time to out-of-bed activity, the first flatus/bowel motion time, complications, and hospital stay were analyzed retrospectively. ResultsTwenty-six patients were successfully carried out totally laparoscopic splenectomy via anterior approach. The average operation time was 93 min (72-120 min). The average blood loss was 60 mL (10-80 mL). The postoperative time to out-of-bed activity was 24 h. The first flatus/bowel motion time was 2-3 d. The average hospital stay was 7 d (6-9 d). The postoperative pancreatic fistula (Grade A) occurred in 1 patient, who recovered well on day 6 by postoperative drainage management. After 5-32 months of following-up, all patients recovered smoothly without any long-term complications. ConclusionThe preliminary results of limited cases in this study show that totally laparoscopic splenectomy via anterior approach is feasible, safe, and minimally invasive.
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.
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 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.
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.
