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
For portal hypertensive patients with splenomegaly and hypersplenism, splenectomy is an effective surgery to relieve the complications. However, patients who have undergone splenectomy often suffer from portal venous system thrombosis, a sequela that requires prophylaxis and timely treatment to avoid deterioration and death. The aim of this study is to investigate the feasibility of predicting post-splenectomy thrombosis using hemodynamic metrics based on computational models. First, 15 portal hypertensive patients who had undergone splenectomy were enrolled, and their preoperative clinical data and postoperative follow-up results were collected. Next, computational models of the portal venous system were constructed based on the preoperative computed tomography angiography images and ultrasound-measured flow velocities. On this basis, splenectomy was mimicked and the postoperative area of low wall shear stress (ALWSS) was simulated for each patient-specific model. Finally, model-simulated ALWSS was statistically compared with the patient follow-up results to investigate the feasibility of predicting post-splenectomy thrombosis using hemodynamic metrics. Results showed that ALWSS could predict the occurrence of post-splenectomy thrombosis with the area under the receiver operating characteristic curve (AUC) equal to 0.75. Moreover, statistical analysis implied that the diameter of the splenic vein is positively correlated with ALWSS (r = 0.883, p < 0.0001), and the anatomical structures of the portal venous system also influence the ALWSS. These findings demonstrated that the computational model-based hemodynamic metric ALWSS, which is associated with the anatomorphological features of the portal venous system, is capable of predicting the occurrence of post-splenectomy thrombosis, promoting better prophylaxis and postoperative management for portal hypertensive patients receiving splenectomy.

Abstract
Background/Aims: To compare laparoscopic splenectomy and esophagogastric devascularization (LSED) with endoscopic variceal ligation (EVL) plus laparoscopic splenectomy (LS) in treating esophagogastric variceal bleeding (EGVB) caused by portal hypertension (PH). Methods: Between January 2015 and May 2022, 87 patients with PH caused by hepatitis B cirrhosis were included in the retrospective study (34 in LSED versus 53 in EVL + LS). Results: The clinical features of both groups were well-matched (P > .05). The EVL+LS group was associated with shorter operation time, lower operative blood loss, faster gastrointestinal (GI) recovery, lower C-reactive protein levels, and shorter hospital stays after operation (P < .05). Operative morbidity was more significant in the LSED group (19 55.9% versus 18 33.9%) (P < .05). On postoperative days 1 and 3, albumin levels were remarkably lower (P < .05) in the LSED group. The mean follow-up was 24.3 months for LSED and 26.5 for EVL+LS. Hematological parameters, hepatic functional status, hepatic hemodynamics, and endoscopy indicated a substantial improvement in both groups (P < .05), but no significant difference was identified (P > .05). There was no discernible difference in the incidence of GI bleeding between the two groups (P > .05). Conclusion: EVL+LS is a safer, simpler, and more minimally invasive treatment of EGVB secondary to PH.

Predictors of Long-Term Rebleeding Risk in Cirrhotic Patients Undergoing Esophagogastric Devascularization and Splenectomy: Impact of Portal Vein Thrombosis and Hemoglobin Levels. Med Sci Monit 2023; 29:e941153. [PMID: 37908069 PMCID: PMC10921968 DOI: 10.12659/msm.941153] [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: 05/18/2023] [Accepted: 08/09/2023] [Indexed: 11/02/2023] Open
Abstract
BACKGROUND Esophagogastric devascularization and splenectomy (EGDS) is widely used to treat patients with portal hypertension in China. This study aimed to determine risk factors that increase risk of rebleeding after EGDS and evaluate the effect of portal vein thrombosis (PVT) on rebleeding rates after EGDS. MATERIAL AND METHODS Clinical data of patients with cirrhosis (n=138) who underwent EGDS between December 2010 and January 2016 were retrospectively analyzed. Patients were assigned to rebleeding or non-rebleeding groups and followed up. Univariate and multivariate Cox regression analyses identified the independent predictors of 3-year and 5-year rebleeding. RESULTS A total of 138 consecutive patients who underwent EGDS and met the inclusion criteria were enrolled. Total bilirubin (HR: 2.392, 95% CI 1.032-5.545, P=0.042) and PVT (HR: 3.345, 95% CI 1.477-7.573, P=0.004) predicted 3-year rebleeding during univariate analysis. Multivariate analysis revealed that PVT (HR: 3.967, 95% CI 1.742-9.035, P=0.001) was an independent predictor. Hemoglobin >87.5 g/L (HR: 3.104, 95% CI 1.283-7.510, P=0.012) and PVT (HR: 2.349, 95% CI 1.231-4.483, P=0.010) were predictors of 5-year rebleeding during multivariate analysis. Albumin >37.5 g/L was an independent predictor of rebleeding in patients with PVT at 3 and 5 years (HR: 3.964, 95% CI 1.301-9.883, P=0.008; HR: 3.193, 95% CI 1.275-7.997, P=0.013, respectively). CONCLUSIONS PVT is associated with increased 3-year and 5-year rebleeding rates after EGDS but not at 10 years. Also, hemoglobin >87.5 g/L predicted rebleeding at 5 years. Albumin has huge prospects as a predictor of rebleeding at 3 and 5 years in patients with PVT.

Eur J Radiol 2023; 168:111016. [PMID: 37742371 DOI: 10.1016/j.ejrad.2023.111016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 07/13/2023] [Accepted: 07/26/2023] [Indexed: 09/26/2023]
Abstract
PURPOSE The morphometry of the hepatic portal vein is of clinical importance, particularly in pre-operative assessments, surgical management, and diagnoses of liver conditions. This systematic review and meta-analysis aimed to characterize the morphometry of the normal portal vein in both pediatric and adult patients. METHODS The study, conducted using the PRISMA guidelines and registered with PROSPERO, utilized the MEDLINE, EMBASE, SCOPUS and Web of Science databases up to May 2020, and updated to May 2023. All studies reporting extractable data on diameter, length, and cross-sectional area (CSA) of the main, left, and right portal veins (PV, LPV, RPV, respectively) were included. The AQUA Tool was used to assess the quality of the included studies. Data analysis included subgroup analyses based on geographical location, sex, age, and imaging modality. RESULTS A total of 122 studies with 11,637 subjects were eligible for inclusion. Overall, the pooled mean diameter of the PV (PVD) was 10.09 mm (95% CI: 9.56-10.62). Significant differences in diameter were found between pediatric (6.60 mm; 95% CI: 5.38-7.82) and adult (10.72 mm; 95% CI: 10.25-11.19) subjects. Additionally, there was a significantly larger PVD measurement from computed tomography (CT) than other imaging modalities: CT, 13.28 mm (95% CI: 11.71-14.84); magnetic resonance imaging (MRI), 10.50 mm (95% CI: 9.35-11.66) and ultrasound (US), 9.81 mm (95% CI: 9.47-10.16). The mean diameters of the LPV and RPV were 8.27 mm (95% CI: 6.78-9.77) and 8.33 mm (95% CI: 6.70-9.95), respectively. Mean PV length in adults is 48.63 mm (95% CI: 35.63-61.64). Mean CSA of the PV was 1.09 cm2. CONCLUSIONS The study obtained aim to improve the understanding of portal vein anatomy, especially with relevance to surgical interventions of the liver in both pediatric and adult patients. Measurements from ultrasound imaging closely approximates the generated pooled PVD mean for pediatric and adult patients. CT imaging, however, significantly exceeded the established 13 mm threshold for adults. For pediatric patients, a threshold of 8 mm is proposed as a diagnostic upper limit for a normal PVD. Although not significant, the PVD decreased from the portal confluence towards its bifurcation.

Abstract
BACKGROUND It was still controversial that whether the increase of splenic vein (SV) diameter increased the risk of portal vein thrombosis (PVT), which was a severe disease with high mortality, in the clinic. PURPOSES This study, using computational fluid dynamics method, aimed to investigate how the increase of SV diameter affects the portal vein hemodynamics under different anatomical and geometric features of the portal venous system, thus how it induced to PVT. METHODS The ideal models of the portal system, including different anatomical structures according to the location of left gastric vein (LGV) and inferior mesenteric vein (IMV), and different geometric morphological parameters models were established to carry out numerical simulation in this study. In addition, the morphological parameters of real patients were measured to verify the numerical simulation results. RESULTS First, the wall shear stress (WSS) and helicity intensity, which were closely related to the occurrence of thrombosis, gradually decreased with the increase of SV diameter in all models. However, the degree of decrease was bigger in following models: (1) the models with LGV and IMV linking to SV compared with them linking to PV; (2) the models with big angle of PV and SV compared with small angle. In addition, the morbidity of PVT was higher when LGV and IMV linked to SV rather than them linked to PV in the real patients. Moreover, the angle of PV and SV was also different between PVT and non-PVT patients (125.53° ± 16.90° vs. 115.03° ± 16.10°, p = 0.01). CONCLUSION Whether the increase of SV diameter will result in PVT is depended on the anatomical structure of portal system and the angle between PV and SV, this is also the reason leading to the clinical controversy that the increase of SV diameter is the risk factor of PVT.

Abstract
PURPOSE To investigate the efficacy, feasibility, and safety of transjugular intrahepatic portosystemic shunt (TIPS) as a treatment for patients with recurrent portal hypertension with variceal bleeding (RPHVB) who have previously undergone open splenectomy and esophagogastric devascularization (OSED). METHODS The data were retrospectively retrieved from 39 cirrhotic RPHVB patients who had undergone OSED from August 2015 to December 2020. All patients were treated with TIPS using the Viabahn stent. RESULTS Out of the 39 patients included in the study, TIPS was successfully performed in 38 patients with a success rate of 97.44%. One patient had a failed attempt due to cavernous transformation of the portal vein (CTPV). Among the 38 patients who underwent TIPS, 33 patients also underwent varicose vein embolization, while the remaining 5 patients only underwent TIPS procedure. A total of 39 Viabahn stents were implanted, with 5 patients receiving stents expanded to their nominal diameter of 8 mm and the remaining 33 patients having their shunt maintained at a diameter of 6 mm. The postoperative hemostasis rate was 97.37% (37/38). The portal vein pressure (PVP) and portal pressure gradient (PPG) decreased significantly from (31.28 ± 6.24) and (20.61 ± 5.14) mmHg to (19.58 ± 4.69) and (9.24 ± 3.07) mmHg, respectively (P < 0.001). During the follow-up period, the rebleeding rate was 6.09% (2/29), while the incidence of hepatic encephalopathy (HE) and shunt dysfunction was 13.79% (4/29) for each. CONCLUSION Transjugular intrahepatic portosystemic shunt is an effective, feasible and safe treatment for RPHVB patients who have previously undergone OSED. A satisfactory clinical outcome could be achieved with a 6 mm-diameter shunt in most patients.

Abstract
Objective Splenectomy is a vital treatment method for hypersplenism with portal hypertension. However, portal venous system thrombosis (PVST) is a serious problem after splenectomy. Therefore, constructing an effective visual risk prediction model is important for preventing, diagnosing, and treating early PVST in hepatolenticular degeneration (HLD) surgical patients. Methods Between January 2016 and December 2021, 309 HLD patients were selected. The data were split into a development set (215 cases from January 2016 to December 2019) and a validation set (94 cases from January 2019 to December 2021). Patients' clinical characteristics and laboratory examinations were obtained from electronic medical record system, and PVST was diagnosed using Doppler ultrasound. Univariate and multivariate logistic regression analyses were used to establish the prediction model by variables filtered by LASSO regression, and a nomogram was drawn. The area under the curve (AUC) of receiver operating characteristic (ROC) curve and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the differentiation and calibration of the model. Clinical net benefit was evaluated by using decision curve analysis (DCA). The 36-month survival of PVST was studied as well. Results Seven predictive variables were screened out using LASSO regression analysis, including grade, POD14D-dimer (Postoperative day 14 D-dimer), POD7PLT (Postoperative day 7 platelet), PVD (portal vein diameter), PVV (portal vein velocity), PVF (portal vein flow), and SVD (splenic vein diameter). Multivariate logistic regression analysis revealed that all seven predictive variables had predictive values (P < 0.05). According to the prediction variables, the diagnosis model and predictive nomogram of PVST cases were constructed. The AUC under the ROC curve obtained from the prediction model was 0.812 (95% CI: 0.756-0.869) in the development set and 0.839 (95% CI: 0.756-0.921) in the validation set. Hosmer-Lemeshow goodness-of-fit test fitted well (P = 0.858 for development set; P = 0.137 for validation set). The nomogram model was found to be clinically useful by DCA. The 36-month survival rate of three sites of PVST was significantly different from that of one (P = 0.047) and two sites (P = 0.023). Conclusion The proposed nomogram-based prediction model can predict postoperative PVST. Meanwhile, an earlier intervention should be performed on three sites of PVST.

Abstract
BACKGROUND Marked changes in hemodynamics have been suggested to be a potential contributing factor to portal vein thrombosis (PVT) development. This study investigated the effect of portal hemodynamics based on the anatomical structure of the portal venous system on PVT development. METHODS The morphological features of portal venous system in patients with PVT and those without PVT subgroups were compared. In addition, idealized PV models were established to numerically evaluate the effect of the variation in the angulation of superior mesenteric vein (SMV) and splenic vein (SV) on the hemodynamics of portal venous system. RESULTS The angle α (angulation of SMV and SV) in patients with PVT was lower than that in patients without PVT (p < 0.0001), which was the only independent risk factor (odds ratio (OR), 0.90 (95% CI 0.84-0.95); p < 0.0001) for the presence of PVT. With the change in angle α, the flow pattern of blood flow changed greatly, especially the helical flow. When α = 80°, helical flow only appeared at the local PV near the intersection of SMV and SV. When α = 120°, most regions were occupied by the helical flow. In addition, the h2 gradually increased with increasing α, when α = 80°, h2 = 12.6 m/s2; when α = 120°, h2 = 29.3 m/s2. CONCLUSIONS The angulation of SV and SMV was closely associated with PVT development. Helical flow changed following the varying angulation of SV and SMV. Therefore, angulation of SV and SMV may help to identify high-risk cohorts for future PVT development earlier.

Nomogram for Predicting Postoperative Portal Venous Systemic Thrombosis in Patients with Cirrhosis Undergoing Splenectomy and Esophagogastric Devascularization. Can J Gastroenterol Hepatol 2022; 2022:8084431. [PMID: 36387035 PMCID: PMC9652084 DOI: 10.1155/2022/8084431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 06/20/2022] [Accepted: 07/21/2022] [Indexed: 11/06/2022] Open
Abstract
OBJECTIVES The aim of the study is to develop a nomogram for predicting postoperative portal venous systemic thrombosis (PVST) in patients with cirrhosis undergoing splenectomy and esophagogastric devascularization. METHODS In total, 195 eligible patients were included. Demographic characteristics were collected, and the results of perioperative routine laboratory investigations and ultrasound examinations were also recorded. Blood cell morphological traits, including the red cell volume distribution width (RDW), mean platelet volume, and platelet distribution width, were identified. Univariate and multivariate logistic regressions were implemented for risk factor filtration, and an integrated nomogram was generated and then validated using the bootstrap method. RESULTS A color Doppler abdominal ultrasound examination on a postoperative day (POD) 7 (38.97%) revealed that 76 patients had PVST. The results of the multivariate logistic regression suggested that a higher RDW on POD3 (RDW3) (odds ratio (OR): 1.188, 95% confidence interval (CI): 1.073-1.326), wider portal vein diameter (OR: 1.387, 95% CI: 1.203-1.642), history of variceal hemorrhage (OR: 3.407, 95% CI: 1.670-7.220), and longer spleen length (OR: 1.015, 95% CI: 1.001-1.029) were independent risk parameters for postoperative PVST. Moreover, the nomogram integrating these four parameters exhibited considerable capability in PVST forecasting. The nomogram's receiver operating characteristic curve reached 0.83 and achieved a sensitivity and specificity of 0.711 and 0.848, respectively, at its cutoff. The nomogram's calibration curve demonstrated that it was well calibrated. CONCLUSION The nomogram exhibited excellent performance in PVST prediction and might assist surgeons in identifying vulnerable patients and administering timely prophylaxis.

Abstract
BACKGROUND In Asia, laparoscopic splenectomy and azygoportal disconnection (LSD) has been widely regarded as a preferential treatment modality for cirrhotic portal hypertension (PH). However, LSD involves high surgical risk, technical challenges, and many potential postoperative complications. Technology optimization and innovation in LSD aiming to solve to these difficulties has scarcely been reported. In this retrospective study, we aimed to evaluate the clinical therapeutic effect of our cluster technology optimization and innovation on LSD for PH. METHODS From February 2012 to January 2020, 500 patients with cirrhosis who had esophagogastric variceal bleeding and hypersplenism underwent LSD in our department. According to different operation periods, patients were divided into the early-, intermediate-, and late-period groups. We collected information regarding clinical characteristics of all patients as well as their preoperative and postoperative follow-up data. RESULTS Compared with the early-period group, operation time and postoperative hospital stay were all significantly different and gradually declined from the intermediate- and late-period groups, respectively (all P < 0.05). Intraoperative blood loss of these three groups was gradually decreased, with significant differences (P < 0.05). The incidences of delayed gastric emptying and diarrhea in the late-period group were all significantly lower than those in the early- and intermediate-period groups, respectively (all P < 0.05). Compared with the early-period group, the incidence of variceal re-bleeding was significantly lower in the intermediate- and late-period groups (all P < 0.05). CONCLUSION Our cluster technology optimization and innovation of LSD not only contributed to faster recovery and fewer complications but also enhanced surgical safety for patients. It is worth promoting this approach among patients with EVB and hypersplenism secondary to cirrhotic PH.

Predictors of portal vein thrombosis after laparoscopic splenectomy and azygoportal disconnection in hepatitis B cirrhosis: a prospective study. Surg Endosc 2022; 36:4090-4098. [PMID: 34518951 DOI: 10.1007/s00464-021-08730-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 09/06/2021] [Indexed: 01/29/2023]
Abstract
BACKGROUND The thrombosis of the main and intrahepatic branches of the portal vein (TMIP) is potentially lethal and deemed a common complication following laparoscopic splenectomy and azygoportal disconnection (LSD) in patients with cirrhosis and portal hypertension (PH). The predictors of TMIP after LSD remain unclear. The aim of this prospective study was to explore the predictive and risk factors for TMIP after LSD in cirrhotic patients with PH caused only by hepatitis B virus. METHODS From September 2014 to March 2017, we enrolled 115 patients with hepatitis B cirrhosis and PH who successfully underwent LSD. Patients were subdivided into a TMIP group and a non-TMIP group. Univariate and multivariate logistic regression analysis was conducted on 24 items of demographic and preoperative data, to explore the risk factors of TMIP. RESULTS Twenty-nine (25.22%) patients developed TMIP on postoperative day (POD) 7 and 26 (22.81%) patients developed TMIP on POD 30. From POD 7 to POD 30, 12 patients who did not have TMIP at POD 7 were newly diagnosed with TMIP, with portal vein diameter 15.05 ± 2.58 mm. Another 14 patients in whom TMIP had resolved had portal vein diameter 14.02 ± 1.76 mm. Univariate analysis and multivariate logistic regression revealed that portal vein diameter ≥ 13 mm [relative risk (RR) 5.533, 95% confidence interval (CI) 1.222-25.042; P = 0.026] and portal vein diameter ≥ 15 mm (RR 3.636, 95% CI 1.466-9.021; P = 0.005) were significant independent risk factors for TMIP on POD 7 and 30, respectively. CONCLUSION Portal vein diameter ≥ 13 mm and ≥ 15 mm were significant independent predictors for TMIP after LSD in patients with hepatitis B cirrhosis and PH on POD 7 and POD 30, respectively. TRIAL REGISTRATION We registered our research at https://www. CLINICALTRIALS gov/ . The name of research registered is "Warfarin Prevents Portal Vein Thrombosis in Patients After Laparoscopic Splenectomy and Azygoportal Disconnection."

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
OBJECTIVE To investigate clinical characteristics and risk factors of patients with Flupirtine-induced liver cirrhosis complicated with upper gastrointestinal bleeding. METHODS A total of 116 patients with liver cirrhosis admitted to our hospital from July 2018 to July 2019 were selected and divided into bleeding group (liver cirrhosis complicated with upper gastrointestinal bleeding, n = 71) and non-bleeding group (liver cirrhosis, n = 45). The clinical data of patients in the two groups were collected, including general data, liver function, urinalysis, coagulation function and imaging data. Univariate analysis and multivariate logistic regression analysis were utilized to find the influencing factors of liver cirrhosis complicated with upper gastrointestinal bleeding. RESULTS Of the 116 patients, 45 patients had upper gastrointestinal bleeding, with an incidence rate of 38.79%, including 18 patients (40.00%) with rupture of esophageal varices, 9 (20.00%) with rupture of gastric varices, 9 (20.00%) of portal hypertensive gastropathy, 8 (17.78%) with peptic ulcer, 1 (2.22%) with acute erosive hemorrhagic gastritis; 14 (31.11%) experienced recurrent hemorrhage within 72 hours after treatment, but no death occurred. There were 45 cases (38.79%) in the bleeding group, and 71 (61.21%) in the non-bleeding group, and the differences in the course of liver cirrhosis, the degree of esophageal varices, peptic ulcer, portal hypertension, non-steroidal drug medication and TP between the bleeding group and non-bleeding group were significant (P < 0.05). Severe esophageal varices, liver cirrhosis, peptic ulcer, portal hypertension, non-steroidal drug medication, and TP ≥ 16 s were found to be risk factors of liver cirrhosis complicated with upper gastrointestinal bleeding by logistic regression analysis. CONCLUSION Clinically, it is necessary to take corresponding intervention measures to reduce the incidence of upper gastrointestinal bleeding in patients with liver cirrhosis and improve the prognosis of patients with liver cirrhosis.

Abstract
Splenectomy, as an effective surgery for relieving complications caused by portal hypertension, is often accompanied by a significantly increased incidence of postoperative thrombosis in the portal venous system (PVS). While the underlying mechanisms remain insufficiently understood, the marked changes in hemodynamic conditions in the PVS following splenectomy have been suggested to be a potential contributing factor. The aim of this study was to investigate the influences of the anatomorphological features of the PVS on hemodynamic characteristics before and after splenectomy, with emphasis on identifying the specific anatomorphological features that make postoperative hemodynamic conditions more clot-promoting. For this purpose, idealized computational hemodynamics models of the PVS were constructed based on general anatomical structures and population-averaged geometrical parameters of the PVS. In the models, we incorporated various anatomorphological variations to represent inter-patient variability. The analyses of hemodynamic data were focused on the spatial distribution of wall shear stress (WSS) and the area ratio of wall regions exposed to low WSS (ALS). Obtained results showed that preoperative hemodynamic conditions were comparable among different models in terms of space-averaged WSS and ALS (all were small) irrespective of the considerable differences in spatial distribution of WSS, whereas, the inter-model differences in ALS were significantly augmented after splenectomy, with the value of ALS reaching up to over 30% in some models, while being smaller than 15% in some other models. Postoperative ALS was mainly determined by the anatomical structure of the PVS, followed by some morphogeometrical parameters, such as the diameter and curvature of the splenic vein, and the distance between the inferior mesenteric vein and splenoportal junction. Relatively, the angles between tributary veins and trunk veins only had mild influences on ALS. In addition, a marked increase in blood viscosity was predicted after splenectomy, especially in regions with low WSS, which may play an additive role to low WSS in initiating thrombosis. These findings suggest that the anatomical structure and some morphogeometrical features of the PVS are important determinants of hemodynamic conditions following splenectomy, which may provide useful clues to assessing the risk of postsplenectomy thrombosis based on medical imaging data.

Abstract
INTRODUCTION Splenectomy and splenic artery embolization are major treatment options for hypersplenism and portal hypertension in liver cirrhosis, but may lead to splanchnic vein thrombosis (SVT), which is potentially lethal. We conducted a systematic review and meta-analysis to explore the incidence of SVT in liver cirrhosis after splenectomy or splenic artery embolization and the risk factors for SVT. METHODS All relevant studies were searched through the PubMed, EMBASE, and Cochrane Library databases. The incidence of SVT in liver cirrhosis after splenectomy or splenic artery embolization was pooled. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS Sixty-six studies with 5632 patients with cirrhosis were included. The pooled incidence of SVT after splenectomy and splenic artery embolization was 24.6% (95% CI 20.2-29.3%) and 11.7% (95% CI 7.1-17.3%), respectively. A meta-analysis of three comparative studies demonstrated that the incidence of SVT after splenectomy was statistically similar to that after splenic artery embolization (OR 3.15, P = 0.290). Platelet count, mean platelet volume, preoperative splenic or portal vein diameter, preoperative or postoperative portal blood velocity, splenic volume and weight, and periesophagogastric devascularization were significant risk factors for SVT after splenectomy. Postoperative use of preventive antithrombotic therapy was a significant protective factor against SVT after splenectomy. CONCLUSIONS SVT is common in liver cirrhosis after splenectomy and splenic artery embolization. Coagulation and hemostasis factors, anatomical factors, and surgery-related factors have been widely identified for the assessment of high risk of SVT after splenectomy. Prophylactic strategy after splenectomy, such as antithrombotic therapy, might be considered in such high-risk patients.

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.

Research Progress in Chinese Medicine Preparations for Promoting Blood Circulation and Removing Blood Stasis for Cirrhotic Patients with Portal Vein Thrombosis Following Splenectomy. Chin J Integr Med 2020; 28:855-863. [PMID: 32691285 DOI: 10.1007/s11655-020-3271-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/15/2020] [Indexed: 02/07/2023]
Abstract
This article presented an overview of the therapeutic effects of Chinese medicine (CM) preparations for promoting blood circulation and removing blood stasis for patients with portal vein thrombosis (PVT) after splenectomy. Based on published clinical researches of CM preparations for PVT after splenectomy in patients with cirrhotic portal hypertension (CPH), this paper evaluated the incidence of PVT, and explored potential active components and mechanisms of CM preparations. Safflower Yellow Injection, Danshen Injection () Danhong Injection (), and Compound Danshen Dropping Pill () achieved good curative effect alone or combined with anticoagulant therapy. In addition, Compound Biejia Ruangan Tablet () and Anluo Huaxian Pill () can also significantly improve the hemodynamic disorders of portal vein system in patients with cirrhosis. Considering the role of CM preparations in ameliorating the incidence of PVT after splenectomy in patients with CPH, we suggested that future research should provide more attention to CM alone or CM combined with anticoagulant for cirrhosis with PVT.

Abstract
Different kinds of complications after splenectomy in hepatolenticular degeneration patients with hypersplenism have been reported in the past decades, but studies on pancreatic fistula and the corresponding targeted prevention and treatment after splenectomy still remain much unexplored. The present work investigated the pathogenic factors of pancreatic fistula after splenectomy and the variation tendency of amylase in drainage fluid, aiming to verify the significance of monitoring amylase in the abdominal drainage fluid in the early diagnosis of pancreatic fistula after splenectomy. One hundred sixty-seven patients with hepatolenticular degeneration and hypersplenism who underwent splenectomy in the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from January 2016 to August 2018 were selected and analyzed. The amylase in the abdominal drainage fluid was monitored routinely after splenectomy. We also conducted the statistics on the incidence of different types of pancreatic fistula and analyzed the influence factors of pancreatic fistula formation. After splenectomy, biochemical fistula occurred in 11 patients (6.6%), grade B fistula in six patients (3.6%), grade C fistula in one patient (0.6%), and the incidence of pancreatic fistula was 4.2 per cent (biochemical fistula excluded). The amylase in the peritoneal drainage fluid was closely concerned with the incidence of pancreatic fistula according to our statistics. Furthermore, by analyzing the different influence factors of pancreatic fistula, Child-Pugh grading of liver function ( P = 0.041), pancreatic texture ( P = 0.029), degree of splenomegaly ( P = 0.003), and operative method ( P = 0.001) were supposed to be closely related to the formation of pancreatic fistula. Monitoring of amylase in peritoneal drainage fluid is regarded as an important physiological parameter in the early diagnosis of pancreatic fistula after splenectomy, which provides effective clinical reference and plays a significant role in preventing the occurrence and development of pancreatic fistula.

Abstract
BACKGROUND Research about the long-term outcomes of oesophagogastric devascularization and splenectomy (OGDS) to treat portal hypertension (PH) is scarce. This study aimed to evaluate the safety and long-term treatment efficacy of OGDS, especially in elderly patients. METHODS During 2010-2016, open splenectomy and oesophagogastric devascularization (OSOD) and laparoscopic splenectomy and oesophagogastric devascularization were performed in 124 (group A) and 29 (group C) patients diagnosed with PH and liver cirrhosis, respectively. All patients aged less than 65 years. Besides, 39 patients aged 65 years or older undergoing open splenectomy and oesophagogastric devascularization were classified into group B. All clinical data were retrospectively analysed. RESULTS Compared with group A, patients in group C had longer operative time, less blood loss and shorter post-operative hospitalization time. However, for perioperative data, there was no significant difference between group A and group B. During post-operative follow-up, compared with pre-operative condition, all haematology and liver function parameters significantly changed, except for alanine aminotransferase. For post-operative complications, only the portal vein system thrombosis rate was significantly higher in group C than group A. No significant difference was found in the overall survival rate among three groups, when non-variceal-rebleeding-related deaths were excluded. CONCLUSION OGDS remains safe and effective to treat PH secondary to liver cirrhosis and it can be performed successfully in elderly patients and achieve a curative effect that is not inferior to young patients.

Abstract
BACKGROUND In distal pancreatectomy (DP), the position of the pancreas division line (PDL) changes depending on the location or nature of the tumor. Here, we investigated the relationship between PDL and postoperative complications after DP. METHODS We retrospectively analyzed data of 140 patients who underwent DP at Tokyo Medical and Dental University Hospital between January 2011 and September 2018. PDL was defined as the distance from the left margin of the portal vein to the edge of the pancreatic stump on the coronal plane of computed tomography. RESULTS The mean PDL was 15.1 (range 0-74.3) mm. PDL was significantly longer in patients with portal venous system thrombosis (PVST) than in those without PVST (47.6 vs. 0 mm, p < 0.001). The PDLlong (≥ 20 mm) group underwent surgery with a significantly shorter duration (253 vs. 294 min, p < 0.001) and experienced a lower volume of blood loss (20 vs. 256.5 mL, p < 0.001) than the PDLshort (< 20 mm) group. Six months after surgery, the increase in HbA1c level was significantly higher in the PDLshort group than in the PDLlong group (0.5 vs. 0.35%, p = 0.041). Except for PVST, there was no significant difference in postoperative complications between the two groups. CONCLUSIONS In DP, pancreas resection with a longer PDL resulted in a significantly shorter duration of surgery, lower estimated blood loss, and superior glucose tolerance than that with a shorter PDL.

Abstract
Portal vein thrombosis (PVT) in patients with liver cirrhosis is a common complication associated with adverse outcomes. Aim. To build a predictive model for PVT in cirrhotic patients. Materials and methods. A single centre case-control study was carried out. From the database of 1512 cirrhotic patients 94 with newly diagnosed PVT based on contrast-enhanced computed tomography were referred to the Case group. Malignant PVT was an exclusion criterion. Patients without PVT were stratified and matched according to sex, age and etiology of cirrhosis; case-control ratio was 1 : 3-4. The prevalence of PVT in the database, clinical, laboratory, instrumental parameters of the groups were evaluated. Logistic regression model was used to estimate association between variables and PVT. Results and discussion. The overall prevalence of PVT was 6.2% with the highest rates among the patients with HBV infection - 16.7%, nonalcoholic steatohepatitis - 15.6%, alcohol abuse in combination with HCV infection - 11.7%. The best predictive model included variables: Child-Pugh classes B-C (coefficient of regression β=1.853, р=0.001), ascites (β=0.460, р=0.003), hepatocellular carcinoma without vascular invasion (β=2.126, р=0.0001), endoscopic band ligation (β=0.774, р=0.003), azygoportal disconnection (β=2.734, р=0.001), portal hypertensive gastropathy (β=0.793, р=0.017), portal vein diameter (β=0.203, р=0.004), and local factors - ulcerative colitis flare, Clostridium difficile enterocolitis, spontaneous bacterial peritonitis, colorectal cancer, splenectomy, cholecystectomy (β=2.075, р=0.017). The model had accuracy 85.8% (95% CI 81.7-89.4%), sensitivity - 55.1% (95% CI 43.4-66.4%), specificity - 95% (95% CI 91.6-97.3%), and AUC - 0.871 (95% CI 0.826-0.916). Conclusion. Child-Pugh classes B-C, severe portal hypertension, hepatocellular carcinoma without vascular invasion, and local factors were estimated as risk factors of PVT in cirrhotic patients.
