Objective
To explore the risk factors of postoperative portal vein system thrombus (PVST) after laparoscopic splenectomy in treatment of portal hypertension and hypersplenism.
Methods
Clinical data of 76 patients with portal hypertension and hypersplenism who underwent laparoscopic splenectomy in the Sichuan Provincial People’s Hospital from January 2012 to January 2017 were analyzed.
Results
There were 31 patients suffered from PVST (PVST group), and other 45 patients enrolled in non-PVST group.There were significant differences on age, diameter of splenic vein, diameter of portal vein, blood flow velocity of portal vein, level of D-dimer, and platelet count between the PVST group and the non-PVST group (P<0.05), but there were no significant difference on gender, Child-Pugh classification, etiology of cirrhosis, operation time, intraoperative blood loss, postoperative complications, and prothrombin time between the two groups (P>0.05). Multivariate logistic regression analysis showed that, patients with age >50 years (RR=1.31, P=0.02), splenic vein diameter >12 mm ( RR=1.29, P<0.01), portal vein diameter >13 mm (RR=1.55, P=0.01), blood flow velocity of portal vein <18 cm/s ( RR=1.47, P<0.01), increases level of D-dimer (RR=2.89, P=0.03), and elevated platelet count (RR=1.82 P=0.02) had higher risk of postoperative PVST than those patients with age ≤50 years, splenic vein diameter ≤12 mm, portal vein diameter ≤13 mm, blood flow velocity of portal vein ≥18 cm/s, normal level of D-dimer and platelet count.
Conclusion
For patients with portal hypertension and hypersplenism who underwent laparoscopic splenectomy, we should pay more attention to the risk factor, such as D-dimer and so on, to avoid the occurrence of postoperative PVST.
Objective
To explore treatment strategy of pancreatic pseudocyst induced left-sided portal hypertension (LSPH) complicated with hypersplenism.
Methods
The clinical data of 49 cases of pancreatic pseudocyst induced LSPH complicated with hypersplenism from January 2010 to June 2015 in this hospital were retrospectively analyzed. Among them, 36 patients who were not complicated with upper gastrointestinal bleeding were designed to splenectomy group and non-splenectomy group based on splenectomy or not. The epidemiological and clinical features, intraoperative and postoperative results of these two groups were compared.
Results
There were 38 males and 11 females with age ranging from 22 to 67 years old. As for 13 patients suffering LSPH complicated with hypersplenism caused by pancreatic pseudocyst with upper gastrointestinal bleeding, one patient didn’t accept splenectomy, then the upper gastrointestinal bleeding recurred and the hypersplenism was not alleviated after operation; Whereas, the hypersplenisms were relieved in the others patients after operation. In the 36 patients without upper gastrointestinal bleeding who were complicated with hypersplenism, 23 patients were performed splenectomy (splenectomy group) and 13 patients were not (non-splenectomy group). In the splenectomy group, the blood loss, operation time, and intraoperative blood transfusion were significantly more than those of the non-splenectomy group (P<0.05). The hospital stay and the discharged laboratory examinations had no significant differences between the splenectomy group and the non-splenectomy group (P>0.05) except for the platelet count. Furthermore, the incidence of the postoperative upper gastrointestinal bleeding was lower (P<0.05) and the relief rate of hypersplenism was higher (P<0.05) in the splenectomy group as compared with the non-splenectomy group.
Conclusions
For pancreatic pseudocyst induced LSPH with hypersplenism, we should be vigilant and early intervent. Usually, primary focus can be treated only. However, splenectomy can effectively relieve hypersplenism and prevent recurrent bleeding for patients with upper gastrointestinal bleeding or patients with close adhesion of pancreas tail and spleen inflammatory lesions and constricting splenic hilus.
ObjectiveTo analyze risk factors of intraoperative massive hemorrhage in patients with pancreatitis-induced sinistral portal hypertension (SPH) and to explore its strategies of treatment.MethodsThe clinical data of patients with pancreatitis-induced SPH admitted to the West China Hospital of Sichuan University from January 2015 to March 2018 were retrospectively analyzed. The intraoperative massive hemorrhage was defined as the blood loss exceeding 30% blood volume. The factors closely associated with the intraoperative massive hemorrhage were analyzed by the forward logistic regression model.ResultsA total of 128 patients with pancreatitis-induced SPH were enrolled in this study, including 104 males and 24 females, with an average age of 47 years old and a median intraoperative bleeding volume of 482 mL. Among them, 93 patients with pancreatitis-induced SPH caused by the pancreatic pseudocyst after acute pancreatitis and 35 caused by the chronic pancreatitis. There were 36 patients with history of upper gastrointestinal bleeding and 46 patients with hypersplenism. Thirty-six patients suffered from the massive hemorrhage. Among them, 30 patients underwent the distal pancreatectomy concomitant with splenectomy, 1 patient underwent the duodenum- preserving resection of pancreatic head, and 5 patients underwent the pseudocyst drainage. The univariate analysis showed that the occurrence of intraoperative massive hemorrhage in the patients with pancreatitis-induced SPH was not associated with the gender, age, body mass index, albumin level, upper gastrointestinal bleeding, hypersplenism, type of pancreatitis, course of pancreatitis, number of attacks of pancreatitis, size of spleen, maximum diameter of lesions in the splenic vein obstruction site, or number of operation (P>0.05), which was associated with the diameter of varicose vein more than 5.0 mm (χ2=19.83, P<0.01), the intraperitoneal varices regions (χ2=13.67, P<0.01), the location of splenic vein obstruction (χ2=5.17, P=0.03), the operation time (t=–3.10, P<0.01), or the splenectomy (χ2=17.46, P<0.01). Further the logistic regression analysis showed that the varicose vein diameter more than 5.0 mm (OR=6.356, P=0.002) and splenectomy (OR=4.297, P=0.005) were the independent risk factors for the intraoperative massive hemorrhage in the patients with pancreatitis-induced SPH.ConclusionsSplenectomy and having a collateral vein more than 5.0 mm in diameter are independent risk factors for intraoperative massive blood loss in surgeries taken on patients with pancreatitis-induced SPH. Attention should be paid to dilation of gastric varices and choice of splenectomy.
Objective
To summarize the effect of the splenectomy in patients with portal hypertension on the occurrence and recurrence of hepatocellular carcinoma.
Methods
The related literatures about the splenectomy in patients with hepatocirrhosis combined with portal hypertension or patients with hepatocellular carcinoma combined with portal hypertension in recent years were reviewed.
Results
At present, most academics considered that, for patients with hepatocirrhosis combined with portal hypertension, splenectomy could reduce the occurrence of hepatocellular carcinoma. For patients with hepatocellular carcinoma combined with portal hypertension, splenectomy+hepatectomy didn’t increase the perioperative mortality, and it could reduce the recurrence rate of hepatocellular carcinoma.
Conclusion
Splenectomy for patients with portal hypertension is safe, and it can inhibit the occurrence and progress of hepatocellular carcinoma, however, the specific mechanism remain needs further study.
ObjectiveTo evaluate the feasibility and safety of laparoscopic radical antegrade modular pancreatosplenectomy through the ligament of Treitz approach for pancreatic body and tail cancer. MethodsOn 13th November 2017, we selected a patient with a suspicious malignant tumor in the body of pancreas but no evidence of metastasis or local invasion of the retroperitoneum for laparoscopic antegrade modular pancreatosplenectomy through the ligament of Treitz approach. The time of operation, the estimated blood loss, and post-operative complications were observed. ResultsThe procedure was completed successfully in 255 min, and the estimated blood loss was 200 mL, there was no need of transfusion and no significant post-operational complications had been observed. No tumor recurrence or distal metastasis was found after a 12 month’s follow-up. ConclusionLaparoscopic radical antegrade modular pancreatosplenectomy through the ligament of Treitz approach is a feasible and safe procedure for pancreatic body and tail malignant tumor in strictly selected patients.
ObjectiveTo summarize the recent development of surgical treatment for portal hypertension with hypersplenism.
MethodsThe related literatures on various operation treatment of hypertension with hypersplenism at home and abroad in recent years were collected and reviewed.
ResultsThere are many operation treatment methods of hypertension with hypersplenism, includes the pericardial devascularization, subtotal splenectomy, partial splenic embolization, spleen radiofrequency ablation, splenic artery ligation, distal splenorenal shunt, and so on. The different operation methods each has its advantages and disadvantages, but there are a certain percentage of the incidence of complications. At the same time, due to the limited understanding of the function of the spleen in portal hypertension, the treatment of "resecting" or "reserving" spleen has always been the hot spot of the academic dispute.
ConclusionFor what kind of operation method is the most suitable for the treatment of hypertension with hypersplenism is no fixed conclusion.
Objective To investigate the effectiveness and safety of low molecular weight heparin combined with aspirin for perioperative prophylactic anticoagulation in patients with lower extremity fracture after splenectomy. MethodsThe clinical data of 50 patients with splenic rupture combined with lower extremity fracture between January 2009 and June 2022 were retrospectively analyzed. All patients were given enoxaparin sodium at 48 hours after splenectomy, and stopped at 24 hours before fracture surgery. After fracture surgery, the patients were divided into aspirin group (group A, 15 cases), low molecular weight heparin group (group B, 16 cases), and low molecular weight heparin combined with aspirin group (group C, 19 cases) according to different anticoagulation regimens. The treatment course was 28 days. There was no significant difference in gender, age, body mass index, cause of injury, fracture site, time from injury to operation, complications, and other general data between groups (P>0.05). The occurrence of venous thromboembolism (VTE) was observed; hemoglobin (Hb), platelet (PLT), D-D dimer, and fibrinogen degradation product (FDP) were recorded before operation and at 1, 3, and 7 days after operation, and the effect of anticoagulation regimen on coagulation function was observed. The incidences of wound complications and bleeding related complications were recorded, and the total perioperative blood loss, hidden blood loss, and overt blood loss were calculated. Results The incidences of VTE in groups A, B, and C were 13.33% (2/15), 12.50% (2/16), and 5.26% (1/19), respectively, and there was no significant difference between groups (χ2=0.770, P=0.680). There was no portal vein thrombosis and no VTE-related death in the 3 groups. There was no significant difference in the levels of Hb, PLT, D-D dimer, and FDP between groups before and after operation (P>0.05); and there was no significant difference in total perioperative blood loss, hidden blood loss, and overt blood loss between groups (P>0.05). No local skin necrosis was found in all patients. In group A, 1 case occurred redness and swelling of incision; in group B, 1 case had incision discharge, redness, and swelling, and 1 case had fat liquefaction; in group C, 1 case had repeated incision exudation accompanied by local tissue redness and swelling, and 1 case had local hematoma. The incidences of adverse incision in groups A, B, and C were 6.66% (1/15), 12.50% (2/16), and 11.76% (2/19), respectively, with no significant difference (χ2=0.302, P=0.860). There were 4 cases of bleeding related complications, including 1 case of incision ecchymosis in groups A and B respectively, with the incidence of 6.66% and 6.25%, respectively; there was 1 case of incision hematoma and 1 case of bleeding in group C, with the incidence of 11.76%; showing no significant difference in the incidence of bleeding related complications between groups (χ2=0.268, P=0.875). Conclusion Perioperative combined use of low molecular weight heparin and aspirin for prevention of anticoagulation in patients with splenic rupture and lower extremity fracture can effectively prevent the occurrence of VTE without increasing the incidence of complications, which is an effective and safe treatment method. However, whether the incidence of VTE can be reduced needs to be further studied by expanding the sample size.
Objective To evaluate the effect of laparoscopic splenectomy （LS） and open splenectomy （OS） forhypersplenism secondary to liver cirrhosis with portal hypertension. Methods Cochrane Central Register of Controlled Trials， Cochrane Database of Systematic Reviews， Medline， Embase， CINAHL， CBM， CNKI， VIP and WanFang database were searched for randomized control trials or retrospective studies related to the effect of LS and OS for hyper-splenism secondary to liver cirrhosis with portal hypertension. Then studies were screened according to the inclusion and exclusion criterias， data were collected， and quality of studies were evaluated. RevMan 5.1.0 software was used for meta-analysis. Results Seventeen retrospective studies and one randomized control trial were enrolled. The results of meta analysis showed that， the estimated blood loss， postoperative hospital stay， rate of postoperative complication， and WBC level on 1 day after operation of LS group were significantly lower or shorter than those of OS group （P＜0.05）. However， there were no significant differences on operative time， WBC level on 7 days after operation， postoperative platelets （1 day and 7 days after operation）， alanine aminotransferase （1 day and 7 days after operation）， and total bilirubin （1 day and 7 days after operation） between LS group and OS group （P＞0.05）. Conclusions LS may be more effective to reduce blood loss， postoperative hospital stay， and rate of postoperative complication in patients with hypersplenism secondary to liver cirrhosis with portal hypertension in comparison to OS. However， the effectiveness of LS on liver function is not clear.

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.
