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 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.
ObjectiveTo evaluate the operative technique and clinical efficacy of laparoscopic splenectomy (LS) combined with esophagogastric devascularization in treatment of portal hypertension induced by liver cirrhosis. MethodsTwelve cases with esophageal and gastric varices induced by portal hypertension and liver cirrhosis were treated by the LS combined with esophagogastric devascularization in our department from March 2009 to August 2010, which clinical data were analyzed and summarized retrospectively. ResultsThe splenic artery was ligated before the treatment of splenic pedicle in 12 cases, LS combined with pericardial devascularization was successfully performed in 10 cases, 7 cases of which were treated by the level two transection method of splenic pedicle, and 2 cases were converted to open surgery due to intraoperative bleeding. In 10 cases, the operative time was 180-300 min (average 210 min), and intraoperative blood loss was 200-1 000 ml (average 480 ml). The postoperative hospital stay was 8-15 d (average 9 d)， the postoperative complications included plural effusion （lt;300 ml） in 2 cases， mild ascites （lt;300 ml） in 2 cases, and mild pancreatic leakage in 1 case， but all were cured eventually， and no mortality occurred. Followup was conducted in 12 patients for 4 to 20 months (average 7 months), and no rebleeding occurred. ConclusionsLS combined with pericardial devascularization is relatively safe and effective methods in treatment of portal hypertension induced by liver cirrhosis. The keys to success include ligation of splenic artery, and the use of harmonic scalpel combined with ligasure to treat splenic pedicle.

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.
Compared with open surgery, laparoscopic radical resection of the body and tail pancreatic cancer is gradually being accepted due to its shorter hospital stay, reduced intraoperative blood loss, and comparable perioperative and oncological prognosis. The proposal of radical antegrade modular pancreatosplenectomy (RAMPS) has established a standardized approach for resection scope and lymph node dissection in pancreatic body and tail cancers. Studies have confirmed that RAMPS surgery can achieve a higher N1 station lymph node dissection, R0 margin ratio, and satisfactory patient survival rates. Furthermore, RAMPS has demonstrated oncological advantages in terms of postoperative local control. Laparoscopic RAMPS (LRAMPS) has been shown to be technically feasible and to yield long-term oncologic outcomes comparable to open RAMPS. An increasing number of studies have evaluated LRAMPS as the standard surgical modality for resectable body and tail pancreatic cancers. This article discusses the main points and challenges of LRAMPS surgery, and presents some personal experiences.
Objective To summarize the experience of single center for radical antegrade modular pancreatosplenectomy (RAMPS) in the treatment of pancreatic body and tail cancer. Methods The clinical data of 52 patients with pancreatic body and tail cancer who underwent RAMPS surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2013 to December 2016 were retrospectively analyzed. Results All operations of the 52 patients were successfully completed, with no death during hospitalization and 30 days after surgery. The operative time was (463±137) min (198–830 min), the median of intraoperative blood loss was 400 mL (100–2 800 mL), of which 19 cases (36.5%) received intraoperative blood transfusion. The median of hospital stay was 19.5 days (7–58 days). After operation, 18 patients suffered from pancreatic fistula, 5 patients suffered from delay gastric emptying, 7 patients suffered from peritoneal effusion, 3 patients suffered from pleural effusion, 4 patients suffered from abdominal infection, 2 patients suffered from abdominal bleeding. Reoperations were performed in 2 patients. There were 51 patients were followed up for 3–35 months (the median of 18 months) with the median survival time were 16.2 months. During the follow-up period, 21 patients suffered from recurrence or metastasis, of which 8 patients died. The results of Cox partial hazard model showed that, surgical margin ［RR=3.65, 95% CI was (0.06, 5.11), P=0.026］ and adjuvant therapy ［RR=6.43, 95% CI was (1.51, 27.43), P=0.012］ were statistically related with prognosis, the prognosis of patients with negative surgical margin and underwent adjuvant therapy were better than those patients with positive surgical margin and didn’t underwent adjuvant therapy. Conclusions RAMPS is safe and feasible in the treatment of pancreatic body and tail cancer, and it may improve the R0 resection rate. RAMPS combins with adjuvant therapy can contribute to better prognosis.
