Abstract
BACKGROUND Portal vein thrombosis (PVT) is a commonthsn complication after splenectomy in patients with cirrhosis. However, the predictors of postoperative PVT are not known. AIM To investigate the predictors of PVT after splenectomy in patient with cirrhosis. METHODS A total of 45 patients with cirrhosis who underwent splenectomy were consecutively enrolled from January 2017 to December 2018. The incidence of PVT at 1 months, 3 months, and 12 months after splenectomy in patients with cirrhosis was observed. The hematological indicators, biochemical and coagulation parameters, and imaging features were recorded at baseline and at each observation point. The univariable, multivariable, receiver operating characteristic curve and time-dependent curve analyses were performed. RESULTS The cumulative incidence of PVT was 40.0%, 46.6%, and 48.9% at 1 months, 3 months, and 12 months after splenectomy. Multivariable analysis showed that portal vein diameter (PVD) ≥ 14.5 mm and monthsdel end-stage liver disease (MELD) score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy (P < 0.05). Time-dependent curve showed that the cumulative incidence of PVT was significantly different between patients with MELD score ≤ 10 and > 10 (P < 0.05). In addition, the cumulative incidence of PVT in the PVD ≥ 14.5 mm group was significantly higher than that in the PVD < 14.5 mm group (P < 0.05). CONCLUSION Wider PVD and MELD score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy in patient with cirrhosis.

Abstract
BACKGROUND AND AIM Idiopathic portal hypertension (IPH) refers to a relatively rare condition characterized by intrahepatic portal hypertension in the absence of underlying disease such as liver cirrhosis. METHODS We retrospectively reviewed 338 patients with IPH that were diagnosed at the pathological consultation center of our hospital. RESULTS The ratio of male to female patients was 1:1. Mean age at onset was 35.1 ± 16.5 years; male patients on average were 12 years younger than female patients at onset. The median duration from onset to IPH diagnosis was 12 months. In 50 patients, medication use may have been an etiological factor. The most common clinical manifestations were splenomegaly (91.3%) and hypersplenism (68.9%); 57.0% patients presented varicosis, while 25.1% patients had a history of variceal bleeding. Nodular regenerative hyperplasia was found in 22.2% liver biopsies. Among patients for whom laboratory data were available, 65.0%, 50.3%, and 71.4% patients presented leukopenia, anemia, and thrombocytopenia due to hypersplenism. Liver function was mostly in the compensated stage. Female patients showed worse leukopenia and anemia, while male patients were more likely to have abnormal serum transaminase and bilirubin levels. Sixty-seven patients received surgical or interventional treatment. CONCLUSIONS High-quality liver biopsy, detailed clinical information, and expert pathologist are necessary for diagnosis of IPH. IPH can occur concurrently with other liver disease such as hepatitis and drug-induced liver injury. Medication appears to be an important etiological factor for IPH in China. Management approach was largely focused on treatment of portal hypertension and its complications.

Predictors of portal and splenic vein thrombosis after laparoscopic splenectomy: a retrospective analysis of a single-center experience. Surg Today 2018; 48:804-809.

Abstract
PURPOSE Laparoscopic splenectomy (LS) has become the standard operative approach for splenectomy. Portal or splenic vein thrombosis (PSVT) is a serious and common complication after LS, and lethal complications of PSVT can occur when the portal vein is completely occluded by portal vein thrombosis (PVT). We aimed to clarify the predictors of PSVT after LS and to determine which of them were also predictors of PVT. METHODS A total of 56 consecutive patients who underwent elective LS were enrolled in this study. The patients were divided into two groups based on the presence or absence of PSVT after LS. In addition, patients with PSVT were divided into two groups: a PVT group and a non-PVT group. The preoperative and intraoperative clinical data were compared among the groups. RESULTS Thirty (53.6%) patients developed PSVT. The splenic vein diameter was the most useful predictor for the development of PSVT, and 10 mm was an accurate splenic vein diameter cut-off value for use as a predictive factor for PSVT. In addition, the splenic vein diameter was the most useful predictor of the development of PVT from splenic vein thrombosis (SVT), and 14 mm was found to be an accurate cut-off value. CONCLUSION PSVT is a common postoperative complication that is identified on enhanced computed tomography. The splenic vein diameter is not only a predictor of PSVT but also of the development of PVT from SVT.

Diagnosis and treatment guidelines for aberrant portal hemodynamics: The Aberrant Portal Hemodynamics Study Group supported by the Ministry of Health, Labor and Welfare of Japan. Hepatol Res 2017; 47:373-386.

Abstract
Idiopathic portal hypertension (IPH), causing aberrant portal hemodynamics, is a disease with an as yet unidentified cause and no established treatment protocol. The Japanese research group on IPH in Japan was set up in 1975 by the Ministry of Health, Labor and Welfare. Extrahepatic portal obstruction and Budd-Chiari syndrome (BCS) have since been added to the group's research subjects. The aims of the research group are to accurately evaluate the current status of the three diseases in Japan, elucidate their etiology and pathogenesis, and develop new treatments. Due to the long-term efforts of the Japanese research group, aberrant portal hemodynamics has been investigated in a variety of aspects, from epidemiological and pathological studies to molecular biology analyses. As a result, it has been shown that there are abnormal genes in the liver, specific for IPH. In addition, pathological findings of BCS were internationally compared and the difference in findings between Japan and Europe (or North America) has been clarified. Furthermore, it was found that complication rates of hepatocellular carcinoma in BCS were higher in Japan. Based on the research, "Diagnosis and treatment of aberrant portal hemodynamics (2001)", including diagnostic criteria for aberrant portal hemodynamics, was published in 2001. In 2013, it was revised to "Diagnosis and treatment guidelines for aberrant portal hemodynamics (2013)" after the incorporation of diagnosis and treatment in accordance with its current status.

Abstract
For transplant surgeons, end-stage liver disease with portal venous thrombosis and a previous splenorenal shunt (SRS) is a significant challenge during liver transplantation. Thrombosis of the portal vein can be corrected by surgical interventions, such as portal venous thrombectomy or surgical removal of the thrombosed portal vein. Even also placement of a graft between the mesenteric vein and the graft portal vein can be performed. If these maneuvers fail, a renoportal anastomosis (RPA) can be performed to achieve adequate graft inflow. A 51-year-old male patient who had a history of proximal SRS and splenectomy underwent living donor liver transplantation (LDLT) due to cryptogenic cirrhosis. LDLT was performed with RPA using a cadaveric iliac vein graft. The early postoperative course of the patient was completely uneventful and he was discharged 20 d after transplantation. To the best of our knowledge, this was the first patient to receive LDLT with RPA after surgical proximal SRS and splenectomy.

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
The aim of this study is to investigate the efficacy and safety of extracorporeal high-intensity focused ultrasound (HIFU) in treatment of hypersplenism. Fifteen adult dogs, weighing 13-18 kg were divided into three groups: sham group, SVL group undergoing splenic vein ligation (SVL) after laparotomy, and SVL + HIFU group receiving SVL followed by extracorporeal HIFU. Pathologic and hematologic analyses were performed. We also reviewed the clinical data of 19 patients with secondary hypersplenism caused by liver cirrhosis or hepatocellular carcinoma who underwent extracorporeal HIFU. Extracorporeal HIFU significantly diminished the volume of the spleen of animals, coupled with occurrence of coagulation necrosis and fibrosis in the target area. Both platelet and red blood cell counts were significantly restored by HIFU intervention. Similarly, HIFU treatment improved the hematologic parameters in patients with hypersplenism, and no major complications were encountered. Extracorporeal HIFU intervention is effective and safe in managing secondary hypersplenism.
