Predictors of portal vein thrombosis after simultaneous hepatectomy and splenectomy: A single-center retrospective study. Asian J Surg 2024:S1015-9584(24)01503-3. [PMID: 39054154 DOI: 10.1016/j.asjsur.2024.07.131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 03/07/2024] [Accepted: 07/12/2024] [Indexed: 07/27/2024] Open
Abstract
BACKGROUND Although postoperative portal vein thrombosis (PVT) is a frequent complication of splenectomy, few studies have examined PVT after simultaneous hepatectomy and splenectomy (HS). The aim of this study was to clarify the risk factors for and characteristics of PVT after HS. METHODS This retrospective observational study included 102 patients, including 76 with liver cirrhosis (LC) and 26 without, who underwent HS between April 2004 and April 2021. The incidence and location of postoperative PVT detected on contrast-enhanced CT 1 week after surgery were analyzed. In addition, pre- and intraoperative parameters were compared between patients with postoperative PVT and those without in order to determine risk factors for PVT after HS. RESULTS Among the 102 patients, 29 (28.4 %), including 32.9 % with LC and 15.4 % without LC, developed PVT after surgery. Among the 29 patients with PVT, 21 (72.4 %), 4 (13.8 %), and 4 (13.8 %) developed thrombus in the intrahepatic portal vein only, extrahepatic portal vein only, and both the extra- and intrahepatic portal veins, respectively. Multivariable analysis showed that preoperative splenic vein dilatation was an independent risk factor for PVT after HS (odds ratio: 1.53, 95 % confidence interval: 1.156-2.026, P = 0.003). CONCLUSION Our results suggest that splenic vein dilatation is an independent risk factor for PVT after simultaneous HS, and that PVT after HS occurs more frequently in the intrahepatic portal vein. After HS for cases with dilated splenic veins, we should pay particular attention to the PVT development in the intrahepatic portal vein regardless of the type of liver resection.

J Thromb Haemost 2024; 22:1347-1357. [PMID: 38309434 DOI: 10.1016/j.jtha.2024.01.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 01/23/2024] [Accepted: 01/23/2024] [Indexed: 02/05/2024]
Abstract
BACKGROUND Thrombin generation (TG) in the presence of thrombomodulin (TG-TM) in the plasma of patients with cirrhosis (PWC) is tilted toward a hypercoagulable phenotype. Low protein C and elevated factor VIII levels play a role, but other determinants, such as the prothrombin/antithrombin pair, must also be studied. OBJECTIVES The objectives were (i) to quantitatively assess the subprocesses (prothrombin conversion and thrombin decay) and (ii) to understand the underlying mechanism by studying TG dynamics after prothrombin and antithrombin plasma level correction in PWC. METHODS We studied TG-TM in plasma samples of 36 healthy controls (HCs) and 41 PWC with prothrombin and antithrombin levels of <70% and after their correction. We initiated coagulation with an intermediate picomolar concentration of tissue factor. We determined the overall thrombin potential, prothrombin conversion, and thrombin decay. RESULTS TG-TM was increased in PWC compared with HC due to impaired thrombin inhibition. Indeed, thrombin decay capacity (min-1) decreased from 0.37 (0.35-0.40) in HC to 0.33 (0.30-0.37) in the Child-Turcotte-Pugh A (CTP-A; P = .09), 0.27 (0.26-0.30) in the CTP-B (P < .001), and 0.20 (0.19-0.20) in the CTP-C (P < .001) group. Concomitant correction of prothrombin and antithrombin increased endogenous thrombin potential with prothrombin conversion surpassing thrombin decay. By contrast, when we corrected only antithrombin, TG-TM was normalized and even consistent with a hypocoagulable phenotype in the CTP-C group. CONCLUSION Our results highlight that in PWC, hypercoagulability (evidenced in the presence of TM) is due to impaired thrombin decay, whereas low prothrombin levels do not translate into decreased prothrombin conversion, likely due to altered TM-activated protein C negative feedback.

Abstract
Background: Portal vein thrombosis (PVT) is a rare disease with an estimated incidence of 2 to 4 cases per 100,000 inhabitants. The most common predisposing conditions for PVT are chronic liver diseases (cirrhosis), primary or secondary hepatobiliary malignancy, major infectious or inflammatory abdominal disease, or myeloproliferative disorders. Methods: PVT can be classified on the basis of the anatomical site, the degree of venous occlusion, and the timing and type of presentation. The main differential diagnosis of PVT, both acute and chronic, is malignant portal vein invasion, most frequently by hepatocarcinoma, or constriction (typically by pancreatic cancer or cholangiocarcinoma). Results: The management of PVT is based on anticoagulation and the treatment of predisposing conditions. The aim of anticoagulation in acute thrombosis is to prevent the extension of the clot and enable the recanalization of the vein to avoid the development of complications, such as intestinal infarction and portal hypertension. Conclusions: The treatment with anticoagulant therapy favors the reduction of portal hypertension, and this allows for a decrease in the risk of bleeding, especially in patients with esophageal varices. The anticoagulant treatment is generally recommended for at least three to six months. Prosecution of anticoagulation is advised until recanalization or lifelong if the patient has an underlying permanent pro-coagulant condition that cannot be corrected or if there is thrombosis extending to the mesenteric veins.

Abstract
AIM The aim of this study was to evaluate the efficacy and safety of the anticoagulants for the prevention of portal vein system thrombosis (PVST) in patients with cirrhosis after splenectomy and explore the optimal time of anticoagulant administration. METHODS A systematic literature search was performed using PubMed, Embase and China Biology Medicine disc (CBM)databases, so as to screen out studies comparing the prognoses between cirrhotic post-splenectomy patients treated with and without anticoagulants. The parameters that were analyzed included the incidence of PVST and postoperative bleeding. RESULTS With a total of 592 subjects, we included 8 studies (6 observational and 2 randomized trials) that fulfilled the inclusion criteria. We found that the incidence of PVST was significantly lower in the anticoagulation group during the first 6 months of anticoagulant administration. And the largest difference in the incidence of PVST between the anticoagulation and control groups was observed at 3 months (odds ratio 0.17(0.11~0.27); P = 0.767; I2 = 0.0%) and 6 months (OR = 0.21(0.11~0.40); P = 0.714; I2 = 0.0%) postoperatively. The incidence of bleeding was not significantly higher in the anticoagulation group (odds ratio 0.71 (0.30~1.71); P = 0.580; I2 = 0.0%). CONCLUSION Low-molecular weight heparin (LMWH) and warfarin can decrease the incidence of PVST in post-splenectomy cirrhotic patients without an increased risk of bleeding. And the optimal use time of warfarin is 6 months after splenectomy.

Abstract
Portal Vein Thrombosis (PVT), a common complication of advanced liver disease, is defined as an obstruction of the portal vein due to thrombus formation that can extend to the superior mesenteric and splenic veins. It was believed that PVT occurred predominantly due to prothrombotic potential. However, recent studies have shown that decreased blood flow related to portal hypertension appears to increase PVT risk as per Virchow's triad. It is well known that there is a higher incidence of PVTs in cirrhosis with a higher MELD and Child Pugh score. The controversy for management of PVTs in cirrhotics lies in the individualized assessment of risks versus benefits of anticoagulation, since these patients have a complex hemostatic profile with both bleeding and procoagulant propensities. In this review, we will systematically compile the etiology, pathophysiology, clinical features, and management of portal vein thrombosis in cirrhosis.

Abstract
BACKGROUND Portal vein system thrombosis (PVST) is a common postoperative complication brought by laparoscopic splenectomy and pericardial disconnection (LSD) among patients who suffered from portal hypertension and hypersplenism. This research lies mainly in probing into the risk factors of PVST and evaluating the effects of warfarin on PVST prevention. MATERIALS AND METHODS We took 131 individuals who have carried out LSD from January 2015 to January 2021. Patients were divided into warfarin group (n = 68) and aspirin group (n = 63). Meanwhile, thrombosis factors were analyzed in PVST arm (n = 48) and non-PVST arm (n = 83). RESULTS We analyzed the early postoperative anticoagulation effect, 20 patients (29.4%) in the warfarin group developed PVST, and 28 patients (44.4%) in the aspirin group. The chance to PVST during the first year after operation was lower in the warfarin group than in the aspirin group (F = 13.43, P = 0.006). Risk factors for PVST were analyzed, and diabetes, the diameter of the portal vein and splenic vein, and the velocity of portal blood flow were statistically significant between the PVST arm and non-PVST arm (P < < 0.05). Multiple logistic regression analyses have shown that diabetes, portal vein diameter, splenic vein diameter, and the velocity of portal blood flow were the risk factors of PVST. CONCLUSIONS The portal vein diameter, splenic vein diameter, portal vein flow velocity, and diabetes are risk factors for the PVST after LSD. The prophylactic use of warfarin anticoagulation markedly decreases the probability of occurrence of the PVST in patients with portal hypertension after LSD compared to aspirin.

Abstract
Background Portal vein system thrombosis (PVST) is a common and serious complication after splenectomy. Key factors, including wider diameters of the portal vein, decreased liver function, and high flow volume of portosystemic collateral vessel, are recognized PVST risks. Relationships between PVST and altered hemorheology, including increased plasma viscosity, remain unclear. We investigated hemorheological alterations and explored risk factors of PVST in patients with cirrhosis after splenectomy. Material/Methods Data on patients with cirrhosis who underwent splenectomy were collected retrospectively from January 2018 to June 2020. Color Doppler ultrasonography was performed after splenectomy. Hemorheological indexes were compared between groups. Receiver operating characteristic (ROC) analysis was conducted to analyze risk factor cutoff values. Univariate and multivariate analyses were conducted to explore risk factors of PVST. Results A total of 50 patients were divided into a PVST group (n=30) and control group (n=20). Hemorheological indexes of activated partial thromboplastin time, fibrinogen degradation products (FDP), D-dimer, middle shear rates 50 and 30, low shear rates 5 and 1, and hematocrit in the PVST group were significantly higher than those of the control group (P<0.05). FDP and low shear rate 1 were found to be risk factors of PVST after splenectomy by multivariate analysis. ROC analysis showed that the cutoff points for FDP and low shear rate 1 were ≥38.6 ug/mL and ≥16.855 mPa.s, respectively. Conclusions PVST after splenectomy is closely related to hemorheological alteration. FDP and low shear rate 1 may be valuable markers of PVST.

Abstract
BACKGROUND AND AIMS Portal vein thrombosis is a serious adverse event that occurs during liver cirrhosis. We performed a meta-analysis to evaluate the safety and efficacy of anticoagulant therapy and prophylactic anticoagulant therapy in cirrhosis patients with (/without) portal vein thrombosis. METHODS Eligible comparative studies were identified by searching the following electronic databases: PubMed, Embase, Cochrane Library, Web of Science, and CNKI. A meta-analysis was performed to calculate odds ratios and 95% confidence intervals using fixed-effects models. Recanalization and thrombus progression were defined as the primary outcomes. Secondary outcomes included adverse events and death mortality. RESULTS A total of 3479 patients were included in this analysis. Compared with the control group, the recanalization rate in the anticoagulant therapy group was increased (P < 0.00001) in patients with cirrhosis and portal vein thrombosis without increasing adverse events. Multiple use of enoxaparin in small doses is safer than single large doses (P=0.004). Direct oral anticoagulants are more effective (P < 0.00001) and safer than traditional anticoagulants. Prophylactic anticoagulant therapy can effectively prevent portal vein thrombosis formation (P < 0.00001). CONCLUSIONS Anticoagulation therapy can treat or prevent portal vein thrombosis in patients with liver cirrhosis and is a relatively safe treatment.

Abstract
Background Whether hepatocellular carcinoma (HCC) patients with hypersplenism can benefit from splenectomy is unclear. This study aimed at exploring the efficacy and safety of concurrent splenectomy for HCC patients with hypersplenism. Methods PubMed, EMBASE and Web of Science databases were systematically searched to compare data on the combination of hepatectomy or transhepatic arterial infusion (TAI) with splenectomy (the splenectomy group) with data on hepatectomy or TAI alone (the non-splenectomy group) for the treatment of HCC with hypersplenism. Prospective clinical trials or retrospective cohort studies from inception to May 10, 2020 were considered eligible for this analysis. The relevant outcomes, including patients’ demographics, clinicopathologic characteristics, perioperative indices and long-term outcomes, were independently extracted by two investigators. Publication bias for overall survival (OS) and disease-free survival (DFS) was qualitatively assessed by funnel plots and quantitatively evaluated by Begg’s and Egger’s tests. Results Nine retrospective studies including 1,650 patients were analyzed. Short-term outcomes suggested that the incidence rate of postoperative complications, including portal or splenic vein thrombosis [odds ratio (OR) =26.28, P<0.001] and pancreatic injury (OR =14.89, P=0.001), was significantly higher in the splenectomy group, whereas the perioperative mortality rate was similar between the splenectomy and non-splenectomy groups (P=0.541). Long-term outcomes indicated that the occurrence of variceal re-hemorrhage (OR =0.31, P<0.001) and tumor progress or recurrence (OR =0.62, P=0.001) was markedly reduced for patients who underwent splenectomy, while the long-term mortality rates were not statistically different between the two groups (P=0.087). The prognostic evaluation revealed that the OS and DFS were comparable between the splenectomy and non-splenectomy groups [for OS: hazard ratio (HR) =0.77, 95% confidence interval (CI): 0.53–1.13; for DFS: HR =0.87, 95% CI: 0.63–1.19]. Funnel plots suggested an HRs symmetric distribution for OS and DFS. Begg’s and Egger’s tests confirmed that there was no significant HR publication bias for OS and DFS. Conclusions Due to the significant progress in surgical techniques and perioperative care, concomitant splenectomy should be considered as an optional treatment for some HCC patients with hypersplenism.

[PMID: 33883982 PMCID: PMC8056059 DOI: 10.17179/excli2020-3120] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 02/22/2021] [Indexed: 12/20/2022]
Abstract
This study aimed to evaluate the safety and efficacy of rivaroxaban in preventing portal vein system thrombosis (PVST) in patients with liver cirrhosis after splenectomy and pericardial devascularization. 70 cirrhotic patients undergoing splenectomy and pericardial devascularization were randomly assigned to rivaroxaban treatment (n=35) or low-molecular weight heparin (LMWH) plus warfarin treatment (n=35) for 30 days in this randomized controlled trial. The primary endpoint is the PVST formation. Ultrasound doctors and radiologists were blinded to the randomization results. Both groups received routine outpatient inspection every month and were followed for one year. 17 patients (48.6 %) in rivaroxaban group developed PVST, compared with 27 patients (77.1 %) in LMWH plus warfarin group (P=0.025). The incidence of PVST during the first year postoperation was significantly lower in rivaroxaban group than in LMWH plus warfarin group (F=7.901, P=0.006). The intra-group comparisons versus baseline showed the liver function improved from POD 21 to POM 1, and coagulation function improved from POM 2, in rivaroxaban group. In contrast, the liver function improved from POM 1 to POM 2, and coagulation function improved from POM 4, in LMWH plus warfarin group. The prophylactic use of rivaroxaban significantly decreases the incidence of PVST after splenectomy and pericardial devascularization in cirrhotic patients compared to LMWH plus warfarin treatment. Besides, rivaroxaban treatment was safe and effective and associated with better liver and coagulation functions improvement than LMWH plus warfarin treatment.

Abstract
PURPOSE Although decreased antithrombin-III (AT-III) is a risk factor for portal vein thrombosis (PVT) in patients with liver cirrhosis, the association between postoperative PVT and postoperative AT-III levels is unknown in patients undergoing hepatectomy. METHODS Patients who underwent hepatectomy between 2015 and 2018 were retrospectively analyzed. Postoperative PVT was assessed on CT at days 6-9 after hepatectomy. One-to-one propensity score (PS) matching was used to match the baseline characteristics. RESULTS Of the 295 patients included in this analysis, 19 patients (6.4%) were diagnosed with postoperative PVT. The AT-III level on postoperative day (POD) 3 predicted postoperative PVT with a sensitivity/specificity of 74%/59% (AUC, 0.644; cut-off value, 60%; p = 0.032). Multivariate analysis revealed that AT-III levels ≤ 60% on POD3 (OR, 3.01; 95% CI 1.02-8.89; p = 0.046), cirrhosis (OR, 5.88; 95% CI 1.92-18.0; p = 0.002) and right-sided hepatectomy (OR, 4.16; 95% CI 1.45-11.9; p = 0.0079) were significant risk factors for postoperative PVT. After PS matching, 56 patients with and without AT-III supplementation were analyzed. The two groups had a similar incidence of PVT (p = 0.489). CONCLUSIONS Patients with AT-III levels ≤ 60% on POD3 should be carefully followed up regarding postoperative PVT. Our results did not support the efficacy of routine AT-III supplementation for the prophylaxis of postoperative PVT.

Front Med (Lausanne) 2021; 8:630660. [PMID: 33614687 PMCID: PMC7890015 DOI: 10.3389/fmed.2021.630660] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Accepted: 01/13/2021] [Indexed: 11/13/2022] Open
Abstract
Objectives: Portal vein thrombosis (PVT) is a rare and severe clinical phenotype of antiphospholipid syndrome (APS) with a poor prognosis. Anticoagulation therapy is efficient but is associated with potentially severe bleeding episodes, especially for those patients with thrombocytopenia. We conducted this case-control study to explore the clinical features and associated factors of PVT in APS patients, the re-canalization rate of the PVT after anticoagulation and investigate the beneficial effects of early initiation of anticoagulation in patients with APS associated PVT. Methods: We enrolled patients with APS associated PVT as the case group, and age-, and entry-time-matched APS patients without PVT (1:2) as the control group. We explored the associated factors of PVT in APS patients using multivariate logistic regression analysis. The re-canalization rate of the PVT after anticoagulation was analyzed using the survival analysis. Results: A total of 34 patients (8 males and 26 females) with APS-PVT were enrolled, with a median follow-up time of 3 years (1.5, 7 years). Multivariate logistic regression analysis showed that thrombocytopenia (OR 6.4, 95%CI 1.561-26.218, P = 0.01), hypersensitive c-reactive protein >3 mg/L (OR 4.57, 95%CI 1.426-14.666, P = 0.011), anti β2GPI positive (OR 5, 95%CI 1.816-13.772, P = 0.002) and aPL double-positive (OR 4.08, 95%CI 1.312-12.429, P = 0.013) were independent associated factors for PVT in APS. Survival analysis revealed that effective anticoagulation could increase re-canalization rate significantly (log-rank p = 0.001), with better prognosis (lower mortality rate, log-rank p = 0.045). Conclusions: PVT could be the first presentation of APS with insidious onset and atypical clinical symptoms and easily be misdiagnosed. For patients with APS, double aPLs positive, thrombocytopenia, and inflammation could be the associated factors of PVT. Early diagnosis and anticoagulation treatment can bring thrombus re-canalization thereby significantly improving the prognosis.

Abstract
BACKGROUND Post-hepatectomy portal vein thrombosis (PH-PVT) is a severe complication. The risk factors of PH-PVT after laparoscopic and open hepatectomy have not been clarified yet. We aimed to retrospectively investigate the risk factors and outcome of PH-PVT in patients with primary liver cancer. METHODS We enrolled 622 consecutive patients who underwent hepatectomy in our hospital between January 2006 and August 2016. RESULTS Of 21 patients (3.4%) with PH-PVT, 7 had grade I; 13, grade II; and 1, grade III. The patients with PH-PVT were significantly older than those without PH-PVT. Of the 413 patients who underwent open hepatectomy, those who underwent a major right hepatectomy (4.1%) had a slightly higher incidence of PH-PVT. Of the 209 patients who underwent laparoscopic hepatectomy, those who underwent a left lateral sectionectomy (21.2%) and major right hepatectomy (16.7%) had high incidence rates of PH-PVT. The treatment was only observation in five patients, medication with an antithrombotic drug in 15 patients, and reoperation in one patient. PH-PVT diminished in 17 patients. Cavernous transformation and/or stenosis of the portal vein developed in three patients. The patient with grade III PH-PVT after open right hemihepatectomy underwent reoperation but died of hepatic failure. CONCLUSION This study demonstrated that patient age, left lateral sectionectomy were risk factors of PH-PVT. Laparoscopic left lateral sectionectomy and major right hepatectomy might bring about relatively higher risk of PH-PVT. Major right hepatectomy tends to lead to severe PH-PVT. Careful handling of the PV during hepatectomy and early treatment of PH-PVT are necessary.

Abstract
BACKGROUND Ectopic variceal bleeding is a rare but life-threatening complication of portal hypertension (PH). Oxaliplatin-based chemotherapy for colorectal cancer (CRC) is associated with sinusoidal obstruction syndrome of the liver, which can lead to PH. CASE PRESENTATION Here, we report a successful hybrid surgery that included intraoperative obliteration of ileal conduit stomal varices (ICSVs) for a 66-year-old woman with CRC and liver metastasis that had been treated multimodally during the previous 4 years, including 17 courses of oxaliplatin-based chemotherapy. She was admitted to our hospital for massive hemorrhage from an ileal conduct stoma. Image findings showed ICSVs as a part of portosystemic shunt, which were afferently supplied from the superior mesenteric vein (SMV) and drained by the numerous cutaneous veins connected to the left femoral vein. Obliteration of the stomal varices by interventional radiologic techniques alone was inappropriate because of difficulties of cannulating the efferent cutaneous veins. We, therefore, performed hybrid surgery for the ICSV, which included cannulation into the SMV branch and antegrade obliteration of the varices with a 5% solution of ethanolamine oleate with iopamidol under blocking the SMV flow, using a vascular clip and ligation. Hemorrhage in her ileal conduit stoma disappeared completely. CONCLUSION Customized treatment of ectopic varices should be based on their precise vascular anatomy; hybrid surgery with intraoperative angiography is an alternative treatment for ectopic varices such as ICSV.

Abstract
Background Liver cirrhosis occurs in approximately 80–90% of patients with hepatocellular carcinoma (HCC), and hepatic resection may be dangerous because of well-documented liver cirrhosis, which may be accompanied by portal hypertension (PH). Here we report a patient with advanced HCC with gastric varices and PH who experienced a good clinical course after undergoing balloon-occluded retrograde transvenous obliteration (BRTO), percutaneous transhepatic portal vein embolization (PTPE), hand-assisted laparoscopic (HALS) splenectomy, and right lobectomy of the liver. Case presentation A 72-year-old man had two HCCs with gastric varices. CT revealed one tumor (4.5 cm) located in segment 7, involving the right hepatic vein, adjacent to the middle hepatic vein. Another tumor (2.7 cm) was located in segment 6. He first underwent BRTO for gastric varices and PTPE for planned right lobectomy of the liver. To reduce PH, HALS splenectomy was performed, and uncomplicated right lobectomy of the liver was performed 10 weeks after the first visit. He has remained free of recurrence for at least 1 year. Conclusions Our patient underwent uncomplicated BRTO, PTPE, HALS splenectomy, and right lobectomy of the liver for advanced HCC with PH. Controlling portal pressure is important when hepatic resection is required to treat HCC with PH.

Abstract
Background The aim of this study was to evaluate the safety and efficacy of low‐molecular weight heparin (LMWH) in the prevention of portal vein system thrombosis (PVST) after splenectomy. Methods A systematic search was performed using PubMed, EMBASE, Springer and Cochrane Library databases to screen out studies comparing the prognoses between post‐splenectomy patients treated with and without LMWH. The incidences of PVST and bleeding complications were used as parameters to assess the effect of LMWH. Results Six articles met the selection criteria and were included in this study. A total of 740 patients were involved in these six articles, including 336 patients treated with LMWH (LMWH group) and 385 patients not treated with LMWH (control group). The incidence of PVST in the LMWH group was significantly lower than that in the control group (relative risk 1.782 (1.449–2.192); P = 0.285; I2 = 19.7%), while the incidence of post‐operative bleeding in the LMWH group was significantly higher (relative risk 0.592 (0.195–1.799); P = 0.817; I2 = 0.0%). Conclusion LMWH might decrease the incidence of PVST after splenectomy without a potential risk of bleeding.

Abstract
INTRODUCTION We conducted a retrospective study to investigate the progress of the operative outcome after laparoscopic splenectomy (LS), with a special reference to the administration of prophylactic antibiotics (PA). METHODS The study included 123 patients who underwent elective LS. Operative outcomes before and after the operative procedure was standardized and the impact of treatment with PA on surgical-site infection were investigated. RESULTS With regard to complications, wound infection developed in one (0.8%), portal trunk thrombosis in one (0.8%), pancreatic fistula in one (0.8%), postoperative bleeding in two (1.6%), pleural effusion in one (0.8%), and reoperation because of bowel injury in one (0.8%). Although morbidity did not differ between patients in the early (until the end of 2010) and late (after the beginning of 2011) periods, intraoperative blood loss was lower in patients in the late period. During the late period, no patients required conversion to open surgery. The proportion of patients with surgical-site infection did not differ between those who received PA 1 h before the start of surgery and every 3 h during surgery and those who received PA 1 h before the start of surgery, every 3 h during surgery, and twice a day for 24-72 h after surgery. CONCLUSION Operative outcomes after LS improved after the standardization of the operative procedure. The administration of PA 1 h before surgery and every 3 h during surgery seems to be sufficient to prevent surgical-site infection during LS.

Abstract
Small-for-size graft (SFSG) syndrome after living donor liver transplantation (LDLT) is the dysfunction of a small graft, characterized by coagulopathy, cholestasis, ascites, and encephalopathy. It is a serious complication of LDLT and usually triggered by excessive portal flow transmitted to the allograft in the postperfusion setting, resulting in sinusoidal congestion and hemorrhage. Portal overflow injures the liver directly through nutrient excess, endothelial activation, and sinusoidal shear stress, and indirectly through arterial vasoconstriction. These conditions may be attenuated with portal flow modulation. Attempts have been made to control excessive portal flow to the SFSG, including simultaneous splenectomy, splenic artery ligation, hemi-portocaval shunt, and pharmacological manipulation, with positive outcomes. Currently, a donor liver is considered a SFSG when the graft-to-recipient weight ratio is less than 0.8 or the ratio of the graft volume to the standard liver volume is less than 40%. A strategy for transplanting SFSG safely into recipients and avoiding extensive surgery in the living donor could effectively address the donor shortage. We review the literature and assess our current knowledge of and strategies for portal flow modulation in LDLT.

Abstract
RATIONALE Portal vein thrombosis is defined as any thrombosis that develops in the portal vein system. It is considered a very rare and extremely lethal complication of hepatopancreatobiliary surgery. PATIENT CONCERNS Acute portal vein thrombosis after hepatectomy in patients with hepatolithiasisis very rare. Acute portal vein thrombosis is considered as a dangerous complication after hepatectomy. It is easy to ignore the symptom of acute portal vein thrombosis. Once the appropriate time of treatment is past, it would lead to patients' death. DIAGNOSE Acute portal vein thrombosis after hepatectomy in a patient with hepatolithiasis INTERVENTIONS:: We consider anticoagulation therapy and percutaneous transhepatic portal vein puncture and thrombectomy once the diagnosis of acute portal vein thrombosis is confirmed. OUTCOMES The patient's liver function continued to deteriorate, eventually resulting in death. LESSONS Acute portal vein thrombosis after hepatectomy is difficult to diagnose. The management of acute portal vein thrombosis remains controversial according to its severity, location or time of discovering.

Hand-assisted laparoscopic Hassab's procedure for esophagogastric varices with portal hypertension. Surg Case Rep 2017; 3:111. [PMID: 29058164 PMCID: PMC5651531 DOI: 10.1186/s40792-017-0387-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Accepted: 10/17/2017] [Indexed: 11/21/2022] Open
Abstract
Background Laparoscopic surgery for patients with portal hypertension is considered to be contraindicated because of the high risk of massive intraoperative hemorrhaging. However, recent reports have shown hand-assisted laparoscopic surgery for devascularization and splenectomy to be a safe and effective method of treating esophagogastric varices with portal hypertension. The aim of this study is to evaluate the efficacy of hand-assisted laparoscopic devascularization and splenectomy (HALS Hassab’s procedure) for the treatment of esophagogastric varices with portal hypertension. Case presentation From 2009 to 2016, seven patients with esophagogastric varices with portal hypertension were treated with hand-assisted laparoscopic devascularization and splenectomy in our institute. Four men and three women with a median age of 61 years (range 35–71) were enrolled in this series. We retrospectively reviewed the medical records for the perioperative variables, postoperative mortality and morbidity, and postoperative outcomes of esophagogastric varices. The median operative time was 455 (range 310–671) min. The median intraoperative blood loss was 695 (range 15–2395) ml. The median weight of removed spleen was 507 (range 242–1835) g. The conversion rate to open surgery was 0%. The median postoperative hospital stay was 21 (range 13–81) days. During a median 21 (range 3–43) months of follow-up, the mortality rate was 0%. Four postoperative complications (massive ascites, enteritis, intra-abdominal abscess, and intestinal ulcer) were observed in two patients. Those complications were treated successfully without re-operation. Esophagogastric varices in all patients disappeared or improved. Bleeding from esophagogastric varices was not observed during the follow-up period. Conclusion Although our data are preliminary, hand-assisted laparoscopic devascularization and splenectomy proved an effective procedure for treating esophagogastric varices in patients with portal hypertension.

Abstract
BACKGROUND Laparoscopic gastric devascularization(Lap GDS) and splenectomy (SPL) for gastric varices is technically challenging because of highly developed collateral vessels and bleeding tendency. We investigated the feasibility of customization of Lap GDS and SPL based on CT vascular anatomy. METHODS We analyzed 61 cirrhotic patients with gastric varices who underwent Lap GDS and SPL between 2006 and 2014. Lap GDS was customized according to the afferent feeding veins (left gastric vein (LGV) and/or posterior gastric vein (PGV)/short gastric vein (SGV)) and efferent drainage veins (gastrorenal shunt and/or gastrophrenic shunt, or numerous retroperitoneal veins) based on CT imaging. RESULTS Thirty-four patients with efferent drainage veins suitable for balloon-occluded retrograde transvenous obliteration (B-RTO) underwent B-RTO instead of surgical GDS, with subsequent Lap SPL. Among 27 patients with gastric varices unsuitable for B-RTO, 15 patients with PGV/SGV underwent Lap GDS of the greater curvature and SPL, and 12 patients with LGV or LGV/PGV/SGV underwent Lap GDS of the greater and lesser curvature and SPL. The mean operation time was 294 min and mean blood loss was 198 g. There was no mortality or severe morbidity. Gastric varices were eradicated in all 61 patients, with no bleeding or recurrence during a mean follow-up of 55.9 months. The cumulative 3-, 5-, and 7-year survival rates were 92, 82, and 64%, respectively. CONCLUSIONS Lap GDS and SPL customized based on CT vascular anatomy is a safe and effective procedure for treating gastric varices.

Abstract
Objective To determine the best anticoagulation strategy for the patients who underwent splenectomy with cirrhosis through network meta-analysis. Methods We conducted a systematic review of the literature in PubMed, Embase, and the Cochrane Library database. We extracted data on incidence of Portal vein system thrombosis (PVST) from studies that compared various anticoagulation strategies for use with patients who underwent splenectomy with cirrhosis. Network meta-analysis was conducted in ADDIS by evaluating the different incidence of PVST. Consistency and inconsistency models were developed to identify differences among the therapeutic strategies. Cumulative probability was utilized to rank the strategies under examination. Results. A total of 11 studies containing 1153 patients were included in the network meta-analysis. The results revealed that the application of Antithrombin III was the best anticoagulation option for patients who underwent splenectomy with cirrhosis (P = 0.59). The data of consistency and inconsistency models exhibited basically consistent and showed good convergence. Conclusions Application of Antithrombin III seemed to be the best anticoagulation strategy for cirrhotic patients who underwent splenectomy and should be considered a first-choice clinical reference.

Abstract
BACKGROUND Indications for splenectomy (SP) during whole liver transplantation (LT) remain controversial and SP is often avoided because of common complications. We aimed to evaluate specific complications of these combined procedures. METHODS Data were retrospectively analysed. Splenectomy was performed in patients with splenorenal shunt and/or splenic artery aneurysms or hypersplenism. Patients undergoing simultaneous transplantation and splenectomy (LTSP group) were matched to a non-splenectomy group (LT group). RESULTS Between 1994 and 2013, we included 47 and 94 patients in LTSP and LT groups, respectively. The LTSP patients had a higher rate of pre-LT portal vein thrombosis (PVT). The LTSP group had a longer operative time and greater blood loss. Mean follow-up was 101 months and 5-year survivals were identical (LTSP 85% vs LT 88%, p = 0.831). Hospital morbidity and rejection incidence were comparable, whereas de novo PVT (34% vs 2%, p < 0.0001) and infection (47% vs 25%, p = 0.014) rates were higher after SP. CONCLUSION Splenectomy during LT is technically demanding and exposes recipients to a higher thrombosis rate, therefore portal vein patency must be specifically assessed postoperatively. In selected recipients, SP can be performed without increased mortality but at the price of worsening outcome as evidenced by greater risk of infection and PVT.

Abstract
INTRODUCTION Joubert syndrome is characterized by psychomotor developmental delay, hypotonia, oculomotor abnormalities, occasional retinal dystrophy and cystic kidneys, and frequent and often, striking breathing abnormalities, especially in the neonatal period, with panting tachypnea followed by apnea. We report a case of Joubert syndrome with hepatic fibrosis, portal hypertension, and pancytopenia treated by Hassab's operation. PRESENTATION OF CASE Our patient was a 27-year-old woman with a history of tachypnea, muscle hypotonia, and psychomotor retardation shortly after birth and a diagnosis of Joubert syndrome at 2 years of age. At 19 years of age, she was diagnosed with progressive pancytopenia. At 27 years of age, she visited her local doctor for sudden-onset hematemesis. Endoscopy revealed esophageal varices exhibiting the red color sign and no evidence of recent bleeding. Splenomegaly and development of portal collateral circulation were observed on computed tomography scans. The patient was referred to our hospital, where she was diagnosed with Joubert syndrome and hepatic fibrosis, portal hypertension, and hypersplenism. After performing Hassab's operation, the pancytopenia improved, but anticoagulant therapy was required for splenic vein thrombosis. The patient was discharged on postoperative day 25. Two years following surgery, the gastroesophageal varices were controlled, and no progression of the splenic vein thrombosis or hepatic failure was evident. CONCLUSION This is the first case report of Hassab's operation for congenital hepatic fibrosis in a patient with Joubert syndrome, a rare congenital condition. We achieved a favorable clinical outcome.

Abstract
PURPOSE Portal venous system thrombosis (PVST) is a common and potentially life-threatening complication of splenectomy for portal hypertension due to cirrhosis. METHODS A meta-analysis was conducted to study the necessity of pharmacologic prophylaxis of PVST after splenectomy and how to select the feasible treatment method. Articles were searched through the PubMed, EMBASE, Cochrane Library databases, and CNKI. RESULTS Overall, 404 articles were initially identified, and 11 of them were eligible. Among these selected articles, 7 articles were associated with the necessity of anticoagulation for prevention of PVST, while 5 were about the drug selection. We first demonstrated that the incidence of PVST after splenectomy was significantly lower in patients who received the preventive measures than in those who did not (odds ratio [OR]: 0.22, 95% confidence interval [CI]: 0.13-0.39, P < .00001). Then, we compared the new-style treatment with the conventional treatment and found that patients with new therapy method had lower incidence of PVST than those who received conventional treatment (OR: 0.37, 95% CI: 0.27-0.51, P < .00001). Also, some studies (n = 4) reported that early and combination use of anticoagulation drugs can lead to better outcome for patients with splenectomy and devascularization. CONCLUSION Preventative use of anticoagulant drugs might decrease the incidence of PVST after splenectomy in patients with portal hypertension, new anticoagulant drugs such as low-molecular-weight heparin should be used, and early or combination use of anticoagulation drugs might lead to lower PVST incidence for patients.

Abstract
AIM To evaluate the curative effect of surgical therapy of upper gastrointestinal bleeding in patients with portal hypertension and portal vein thrombosis (PVT).
METHODS Fourteen portal hypertensive patients with PVT and 32 portal hypertensive patients without PVT before operation who underwent surgical treatment for upper gastrointestinal bleeding were included in this study. The clinical features, blood clot formation, and rebleeding after surgery were compared between the two groups.
RESULTS Before surgery, clinical data were comparable in the two groups (P > 0.05). Compared with patients without PVT, patients with PVT had comparable blood coagulation, platelet count, white blood cell count, intraoperative blood loss, days of hospitalization, liver function, ascites, hepatic encephalopathy and thrombosis (P > 0.05), but had more serious PVT after surgery (χ2 = 6.45, P < 0.05). After surgery, the rates of rebleeding at 1, 3 and 5 years were 0%, 21.43% and 21.43% for patients with PVT, and 0%, 6.25%, and 6.25% for patients without PVT, and there were no significant differences between the two groups (P >0.05). Conversion to coronary vein-inferior vena cava shunt alone or plus devascularization was needed in five patients with PVT.
CONCLUSION Splenectomy with pericardial devascularization has a good effect in patients with portal hypertension, upper gastrointestinal hemorrhage and PVT, although some cases need conversion to other procedures such as coronary vein-inferior vena cava shunt alone or plus devascularization.

Abstract
Portal vein thrombosis (PVT) frequently occurs in patients undergoing splenectomy because of liver cirrhosis. Whether the use of postoperative anticoagulants can decrease the incidence of PVT in these subjects is inconclusive. Moreover, the safety of the use of postoperative anticoagulants in the aforementioned patients is a concern. This meta-analysis aims to explore the effectiveness and safety of the preventive anticoagulants to prevent PVT in patients undergoing splenectomy because of liver cirrhosis. Four English language databases (i.e., PubMed, Embase, Cochrane Library, and Web of Science) and four Chinese language databases (i.e., Wanfang, CNKI, Cqvip, and CBM) were searched for randomized controlled trials, cohort studies, and case-control studies on the use of preventive anticoagulants to prevent PVT in patients undergoing splenectomy because of liver cirrhosis from their inception to September 15, 2015. The primary outcome was postoperative PVT incidence. The secondary outcomes included postoperative complications and adverse reaction. Study-specific odds ratios were combined to calculate pooled value through a fixed effects model. A total of 17 original studies were included, involving 1,497 patients. This meta-analysis showed that the preventive anticoagulant group had a lower incidence of PVT than the no anticoagulant group (odds ratio, 0.31; 95% confidence interval, 0.23–0.40; P < 0.05). According to the description of limited studies, the upper gastrointestinal hemorrhage mainly occurred in the no anticoagulant group. Meanwhile, the adverse reaction was trivial in the group using anticoagulants, which could easily be released with no special management. Postoperative anticoagulants can effectively decrease PVT incidence in subjects undergoing splenectomy because of liver cirrhosis. These published studies are more prone to show that no serious negative influence of anticoagulants exists in the aspect of safety. However, further studies are still needed.

Abstract
Splenectomy and gastroesophageal devascularization is the most common clinical treatment for upper gastrointestinal bleeding in patients with portal hypertension. Its advantages include exact treatment and little impact on liver function. However, due to the postoperative high blood coagulation state and hemodynamic changes, it greatly increases the incidence of portal vein thrombosis (PVT), which causes serious complications. Ultrasound, CT and MRI are main methods for the diagnosis of PVT. After diagnosis, using anticoagulation, intervention and surgery can achieve effective control and treatment. PVT mostly occurs perioperatively and therapeutic effects are therefore limited, so perioperative PVT prevention is particularly important. It is recommended that anticoagulation drugs be given preoperatively to prevent PVT formation, injury to the vascular endothelium of the portal vein system be avoided intraoperatively to reduce the formation of spleen vein stump and stabilize postoperative portal vein blood flow dynamics, and ultrasound be performed postoperatively to achieve early diagnosis and treatment.

Abstract
A systematic review and meta-analysis were conducted to evaluate the efficacy and safety of early prophylactic anticoagulation for the prevention of portal vein system thrombosis (PVST) after splenectomy. A systematic search of the PubMed, EMBASE, Springer and Cochrane Library databases was performed to identify studies comparing the outcomes in patients receiving or not receiving regular prophylactic anticoagulation after splenectomy. The quality of the included studies was assessed using the Jadad Score and the Newcastle-Ottawa Scale. Heterogeneity was evaluated using the χ2 and I2 tests. The parameters that were analyzed included the incidence of PVST and anticoagulation-associated complications. A total of seven studies qualified for the review, involving 383 and 283 patients receiving or not receiving regular prophylactic anticoagulation, respectively. The incidence of PVST was significantly reduced with an odds ratio (OR) of 0.31 [95% confidence interval (CI), 0.21-0.46; P<0.00001] in the regular prophylactic anticoagulation group compared with the control group. No difference in the incidence of anticoagulation-associated complications was identified between the two groups (OR=0.60, 95% CI, 0.23-1.56; P=0.30). Early prophylactic anticoagulation was associated with a reduced incidence of PVST, although it was not associated with the incidence of anticoagulation-associated complications. These results indicate that prophylactic anticoagulation could be safely administered after splenectomy, even to cirrhotic patients.

Abstract
BACKGROUND Portal venous system thrombosis (PVST) is a life-threatening complication of liver cirrhosis. We conducted a retrospective study to comprehensively analyze the prevalence and risk factors of PVST in liver cirrhosis. MATERIAL AND METHODS All cirrhotic patients without malignancy admitted between June 2012 and December 2013 were eligible if they underwent contrast-enhanced CT or MRI scans. Independent predictors of PVST in liver cirrhosis were calculated in multivariate analyses. Subgroup analyses were performed according to the severity of PVST (any PVST, main portal vein [MPV] thrombosis >50%, and clinically significant PVST) and splenectomy. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. RESULTS Overall, 113 cirrhotic patients were enrolled. The prevalence of PVST was 16.8% (19/113). Splenectomy (any PVST: OR=11.494, 95%CI=2.152-61.395; MPV thrombosis >50%: OR=29.987, 95%CI=3.247-276.949; clinically significant PVST: OR=40.415, 95%CI=3.895-419.295) and higher hemoglobin (any PVST: OR=0.974, 95%CI=0.953-0.996; MPV thrombosis >50%: OR=0.936, 95%CI=0.895-0.980; clinically significant PVST: OR=0.935, 95%CI=0.891-0.982) were the independent predictors of PVST. The prevalence of PVST was 13.3% (14/105) after excluding splenectomy. Higher hemoglobin was the only independent predictor of MPV thrombosis >50% (OR=0.952, 95%CI=0.909-0.997). No independent predictors of any PVST or clinically significant PVST were identified in multivariate analyses. Additionally, PVST patients who underwent splenectomy had a significantly higher proportion of clinically significant PVST but lower MELD score than those who did not undergo splenectomy. In all analyses, the in-hospital mortality was not significantly different between cirrhotic patient with and without PVST. CONCLUSIONS Splenectomy may increase by at least 10-fold the risk of PVST in liver cirrhosis independent of severity of liver dysfunction.

Resveratrol Reduces the Incidence of Portal Vein System Thrombosis after Splenectomy in a Rat Fibrosis Model. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2016; 2016:7453849. [PMID: 27433290 PMCID: PMC4940576 DOI: 10.1155/2016/7453849] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Accepted: 06/07/2016] [Indexed: 01/01/2023]
Abstract
Purpose. To investigate the preventive effect of resveratrol (RES) on the formation of portal vein system thrombosis (PVST) in a rat fibrosis model. Methods. A total of 64 male SD rats, weighing 200–300 g, were divided into five groups: Sham operation, Splenectomy I, Splenectomy II, RES, and low molecular weight heparin (LMWH), with the former two groups as nonfibrosis controls. Blood samples were subjected to biochemical assays. Platelet apoptosis was measured by flow cytometry. All rats were euthanized for PVST detection one week after operation. Results. No PVST occurred in nonfibrosis controls. Compared to Splenectomy II, the incidences of PVST in RES and LMWH groups were significantly decreased (both p < 0.05). Two rats in LMWH group died before euthanasia due to intra-abdominal hemorrhage. In RES group, significant decreases in platelet aggregation, platelet radical oxygen species (ROS) production, and increase in platelet nitric oxide (NO) synthesis and platelet apoptosis were observed when compared with Splenectomy II (all p < 0.001), while in LMWH group only significant decrease in platelet aggregation was observed. Conclusion. Prophylactic application of RES could safely reduce the incidence of PVST after splenectomy in cirrhotic rat. Regulation of platelet function and induction of platelet apoptosis might be the underlying mechanisms.

Abstract
Background. Both splenectomy (SP) and partial splenic embolization (PSE) are used to treat massive splenomegaly (MSM) secondary to hepatitis B-related liver cirrhosis (HB-LC). This retrospective case-control study was conducted to compare the effects of SP and PSE on these patients. Methods. From July 2004 to January 2012, patients with MSM secondary to HB-LC who underwent SP or PSE were 1 : 1 : 1 matched with similar nonsurgery patients, respectively. Intraoperative situation, hematological indices, liver function, HBV DNA level, HBeAg seroconversion rate, morbidity, and mortality at 6 months postoperatively were compared. Results. Operative time, estimated blood loss, blood transfusion rate, severe pain, postoperative stay, and portal vein thrombosis (PVT) rate in the PSE group were significantly superior to the SP group, although SP and PSE were similar in liver function improvement, HBV suppression, morbidity, and mortality at 6 months postoperatively, and SP even improved WBC and PLT counts higher than PSE. Conclusion. Both SP and PSE are effective in improving liver function, increasing WBC and PLT counts, and suppressing replication of HBV for MSM secondary to HB-LC. Although postoperative improvement in WBC and PLT counts by SP can be higher than PSE, PSE is simple and minimally invasive and has a lower incidence of PVT.

Abstract
Tanshinone IIA is extracted from the root of Salvia miltiorrhiza and used in traditional Chinese medicine for its anti-inflammatory activity and antioxidant effects. The aim of the present study was to investigate the potential protective effects of tanshinone IIA against fibrosis in a rat model of cirrhosis and to elucidate the underlying mechanisms. Male Sprague Dawley rats were used as the model of cirrhosis in the present study. In the cirrhotic rats, the extent of fibrosis, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), heme oxygenase-1 (HO-1) protein expression, serum levels of nuclear factor (NF)-κB, tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-PX), and the protein expression levels of phosphorylated-p38 mitogen-activated protein kinase (MAPK) were all significantly increased. However, the serum malondialdehyde (MDA) activity and protein kinase B (Akt) protein expression were suppressed in cirrhotic rats compared with the sham (control) group. Compared with the cirrhotic group, administration of tanshinone IIA reduced the extent of fibrosis, levels of ALT and AST, HO-1 protein expression, serum NF-κB, TNF-α, IL-1β and IL-6 levels, and the activity of SOD, CAT and GSH-PX. Furthermore, administration of tanshinone IIA significantly increased the inhibition of the serum MDA activity and the Akt protein expression in cirrhotic rats compared with those in the cirrhotic group. The protective effect of tanshinone IIA suppresses fibrosis in a rat model of cirrhosis, and reduces inflammation and oxidative stress, via the HO-1, Akt and p38 MAPK signaling pathway.

Abstract
Bariatric surgery reduces mortality for Americans who meet candidacy criteria and have insurance coverage. Unfortunately, some medically suitable candidates are denied or delayed during insurance approval processes. The long-term impact of such care delays on survival is unknown. Using a prospectively maintained bariatric intake database, we identified consecutive applicants who were evaluated and medically cleared by our multidisciplinary care team and for whom insurance approval was requested. We compared survival in those who were initially approved by their insurance carriers (controls) and those who were initially denied coverage (subjects). Mortality was determined using the Social Security Death Index. Kaplan–Meier survival curves were plotted and the log-rank test for significance was applied. From August 2003 to December 2008, 463 patients (391 females, mean age 45 ± 10 years, mean body mass index 52.5 ± 9.4 kg/m2) were medically cleared for a bariatric procedure. Of these, 363 were approved by insurance on initial request, whereas 100 were denied. Given the study's intention to measure the aggregate impact of delays and denials, nine patients who later came to operation after appeal or coverage change were maintained in the subject cohort. During 0- to 113-month follow-up, six subjects (6%) died compared with seven controls (1.9%), corresponding to a statistically significant survival benefit for patients initially approved for bariatric surgery without delay or denial ( P < 0.001). In conclusion, access to bariatric surgical care was impeded by insurance certification processes in 22 per cent of medically acceptable candidates. Processes that delay or restrict efficient access to bariatric surgery are associated with a 3-fold mortality increase.

Abstract
A 69-year-old man was admitted to hospital with abdominal pain. In the four years prior to his presentation, he had undergone repeated transarterial chemoembolizations and injections for hepatocellular carcinoma. He underwent his 8th transcatheter arterial therapy one month prior to admission. Abdominal X-rays and contrast-enhanced computed tomography showed large amounts of small intestinal gas and venous thrombosis from the portal vein to the superior mesenteric vein, respectively. The thrombosis was reduced after anticoagulation therapy (heparin, antithrombin III, danaparoid sodium and warfarin). This is the first case report of paralytic ileus due to superior mesenteric venous thrombosis after transcatheter arterial therapy for hepatocellular carcinoma with an arterioportal shunt.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) is still challenging in patients with liver cirrhosis and portal hypertension. This study was designed to establish safe and less invasive LS in patients with liver cirrhosis and portal hypertension. STUDY DESIGN We analyzed 390 patients with liver cirrhosis and portal hypertension, who underwent LS between 1993 and 2013. Patients were divided into 3 time periods; early (1993 to 2004, n = 106); middle (2005 to 2008, n = 159); and late (2008 to 2013, n = 125). During the middle time period, standardized technique for LS and selection criteria for hand-assisted LS were adopted. Patients with spleen volume ≥ 1,000 mL by CT volumetry, large perisplenic collateral vessels, and/or Child-Pugh score ≥ 9, underwent hand-assisted LS. During the late time period, the selection criteria were refined and patients with spleen volume ≥ 600 mL underwent hand-assisted LS. RESULTS Conversion to open splenectomy decreased (10.4% in the early time period, 1.9% in the middle time period, and 3.2% in the late time period, p = 0.004), median blood loss decreased (300g, 87g, and 98g, respectively, p < 0.001), and the success rate of pure LS tended to improve (87.2%, 89.5%, and 98.0%, respectively, p = 0.110). Mortality was 0% in each time period, Clavien-Dindo grade IIIb or more complications tended to decrease (5.7%, 2.5%, and 0.8%, respectively, p = 0.081), and technique-related complications decreased significantly (10.4%, 3.8%, and 2.4%, respectively, p = 0.014). CONCLUSIONS Laparoscopic splenectomy is now a safe and less invasive approach, even in patients with liver cirrhosis and portal hypertension, because of its technical standardization with the refined selection criteria for pure or hand-assisted LS.

Abstract
The prognostic impact of portal vein thrombosis (PVT) in liver cirrhosis remains controversial among studies, primarily because the risk stratification of PVT is often lacking. A definition of clinically significant PVT should be proposed and actively improved. Moreover, the risk factors for the development of PVT in liver cirrhosis should be fully recognized to screen and identify high-risk patients. Currently, well-recognized risk factors include a reduced portal vein flow velocity, a worse liver function, splenectomy, liver transplantation, and factor V Leiden and prothrombin G20210A mutations. Novel risk factors include an increased flow volume of portosystemic collateral vessel, thrombopoietin receptor agnonists, and non-selective beta-blockers. In contrast to the traditional perspectives, the abnormalities of procoagulant and anticoagulant factors may not contribute to the development of PVT in liver cirrhosis. Further studies should explore the role of other risk factors, such as antiphospholipid antibodies, methylenetetrahydrofolate reductase C677T gene mutation, hyperhomocysteinemia, and myeloproliferative neoplasms.
