RESUMEN
Bleeding events are feared complications in patients with advanced liver diseases and are associated with morbidity and mortality. In this context, gastrointestinal bleeding, particularly upper gastrointestinal bleeding, has a special clinical importance. In addition to endoscopic measures for hemostasis, reducing portal pressure in particular is a key component of treatment. Although the standard coagulation parameters are often altered in patients with liver diseases, optimizing coagulation plays a secondary role. Typically, a bundle of measures are employed in patients with portal hypertensive bleeding, which nowadays in most cases can halt the bleeding and stabilize the situation. The measures include endoscopy, antibiotic treatment, vasopressor treatment and, if necessary, shunt placement (transjugular intrahepatic portosystemic shunt).
RESUMEN
Portopulmonary hypertension is a rare condition with a poor prognosis. Prompt management is essential for liver transplantation eligibility, a potentially curative option. This report presents a case of severe portopulmonary hypertension that resolved with a conservative therapeutic regimen of tadalafil, macitentan, and inhaled treprostinil, which ultimately enabled successful liver transplantation. There was no recurrence of pulmonary hypertension after transplantation, and the patient was weaned off most pulmonary arterial hypertension therapies. This case report is the first to provide evidence that inhaled treprostinil is a safe and effective alternative to continuous intravenous prostacyclins in portopulmonary hypertension.

BACKGROUND: Partial splenic embolization (PSE) has been suggested as an alternative to splenectomy in the treatment of hypersplenism. However, some patients may experience recurrence of hypersplenism after PSE and require splenectomy. Currently, there is a lack of evidence-based medical support regarding whether preoperative PSE followed by splenectomy can reduce the incidence of complications. AIM: To investigate the safety and therapeutic efficacy of preoperative PSE followed by splenectomy in patients with cirrhosis and hypersplenism. METHODS: Between January 2010 and December 2021, 321 consecutive patients with cirrhosis and hypersplenism underwent splenectomy at our department. Based on whether PSE was performed prior to splenectomy, the patients were divided into two groups: PSE group (n = 40) and non-PSE group (n = 281). Patient characteristics, postoperative complications, and follow-up data were compared between groups. Propensity score matching (PSM) was conducted, and univariable and multivariable analyses were used to establish a nomogram predictive model for intraoperative bleeding (IB). The receiver operating characteristic curve, Hosmer-Lemeshow goodness-of-fit test, and decision curve analysis (DCA) were employed to evaluate the differentiation, calibration, and clinical performance of the model. RESULTS: After PSM, the non-PSE group showed significant reductions in hospital stay, intraoperative blood loss, and operation time (all P = 0.00). Multivariate analysis revealed that spleen length, portal vein diameter, splenic vein diameter, and history of PSE were independent predictive factors for IB. A nomogram predictive model of IB was constructed, and DCA demonstrated the clinical utility of this model. Both groups exhibited similar results in terms of overall survival during the follow-up period. CONCLUSION: Preoperative PSE followed by splenectomy may increase the incidence of IB and a nomogram-based prediction model can predict the occurrence of IB.
RESUMEN
Purpose: Limited data exist regarding outcome and morbidity associated with portosystemic shunts in the pediatric transplant population. Our study assesses the outcomes of pediatric patients who underwent a portosystemic shunt procedure, both with and without liver transplantation (LT). Methods: This study retrospectively reviewed the medical records of pediatric patients aged 0-19 years who underwent shunt placement between 2003 and 2017 at a tertiary care center. The analysis included cases of shunt placement with or without LT. Results: A total of 13 pediatric patients were included in the study with median age of 8.8 years. Among the cases, 11 out of 13 (84.6%) underwent splenorenal shunt, 1 (7.7%) underwent a mesocaval shunt, and another 1 (7.7%) underwent a Modified Rex (mesoportal) shunt. Additionally, 5 out of 13 (38.5%) patients had LT, with 4 out of 5 (80.0%) receiving the transplant before shunt placement, and 1 out of 5 (20.0%) receiving it after shunt placement. Gastrointestinal bleeding resulting from portal hypertension was the indication in all cases. A total of 10 complications were reported in 5 patients; the most common complication was anemia in 3 (23.1%) patients. At the most recent follow-up visit, the shunts were functional without encephalopathy, and no deaths were reported. Conclusion: Shunt placement plays a crucial role in the management of patients with portal hypertension. Our study demonstrates favorable long-term outcomes in pediatric patients who underwent shunt placement. Long term shunt outcomes were similar and unremarkable in patients with LT and without LT.
RESUMEN
OBJECTIVES: To investigate the feasibility of non-contrast-enhanced MR angiography (NCE-MRA) in evaluating the morphology and blood supply of left gastric vein (LGV) in patients with gastroesophageal varices. METHODS: Between March 2021 and October 2022, patients with gastroesophageal varices and who underwent NCE-MRA were retrospectively reviewed. In order to evaluate the blood supply of LGV, superior mesenteric vein (SMV) and splenic vein (SV) were visualized separately by using inflow-sensitive inversion recovery sequence. Two radiologists independently assessed the image quality, determined the origination and the blood supply of LGV, and measured the diameter of LGV. The origination and diameter of LGV were compared between NCE-MRA and contrast-enhanced CT. Differences in blood supply were compared between LGVs with different originations. RESULTS: A total of 53 patients were enrolled in this study and the image quality was categorized as good or excellent in 52 patients. No significant differences were observed in visualizing the origination and the diameter of LGV between NCE-MRA and contrast-enhanced CT (p > .05). The blood supply of LGV was related to its origination (p < .001). Most LGVs with SV origination were supplied by SV. If LGV was originated from the portal vein (PV), about 70% of them were supplied by both SV and SMV. Compared with LGVs with SV origination, LGVs with PV origination showed more chance to receive blood from SMV (p < .001). CONCLUSION: Non-contrast-enhanced MR angiography appears to be a reliable technique in evaluating the morphology and blood supply of LGV in patients with gastroesophageal varices. CLINICAL RELEVANCE STATEMENT: Non-contrast-enhanced MR angiography provides valuable information for the management of gastroesophageal varices. Especially, it benefits patients with renal insufficiency. KEY POINTS: ⢠Non-contrast-enhanced MR angiography using inflow-sensitive inversion recovery technique can be used for evaluating not only morphology as CT but also blood supply of left gastric vein. ⢠The blood supply of left gastric vein is related to its origination and left gastric vein with portal vein origination shows more chance to receive blood from superior mesenteric vein.

ObjectiveTo investigate the efficacy of percutaneous transhepatic variceal embolization (PTVE) alone or in combination with partial splenic embolization (PSE) in the treatment of portal hypertensive hemorrhage in liver cirrhosis through a meta-analysis. MethodsThis study was conducted according to PRISMA guideline, with a PROSPERO registration number of CRD42023396690. Wanfang Med Online, CNKI, CBM, VIP Databases, PubMed, Embase, the Cochrane Library, and Web of Science databases were searched for articles on PTVE alone or in combination with PSE in the treatment of portal hypertensive hemorrhage in liver cirrhosis published up to December 23, 2022. The articles were selected based on inclusion and exclusion criteria, and related data were extracted. The RevMan 5.4.1 statistical analysis software was used to perform the meta-analysis. ResultsEight articles were finally included, with a total sample size of 592 cases, among which there were 316 cases in the PTVE+PSE group and 276 cases in the PTVE group. The meta-analysis showed that compared with the PTVE group, the PTVE+PSE group had significantly lower postoperative portal vein pressure (standardized mean difference [SMD]=-1.75, 95% confidence interval [CI]: -2.33 to -1.16, P<0.05), postoperative diameter of the portal vein (SMD=-0.87, 95%CI: -1.64 to -0.10, P<0.05), postoperative rebleeding rate (odds ratio [OR]=0.17, 95%CI: 0.11 — 0.28, P<0.05), mortality rate (OR=0.13, 95%CI: 0.04 — 0.37, P<0.05), and incidence rate of postoperative portal hypertensive gastrointestinal disease (OR=0.17, 95%CI: 0.07 — 0.45, P<0.05], as well as a significantly higher postoperative platelet level (SMD=0.79, 95%CI: 0.52 — 1.06, P<0.05), while there were no significant differences between the two groups in the incidence rates of postoperative ascites. ConclusionCompared with PTVE alone, PTVE combined with PSE can effectively reduce the rebleeding rate and mortality rate of portal hypertensive hemorrhage in liver cirrhosis, the incidence rate of portal hypertensive gastrointestinal disease, and portal vein pressure, and it can also shorten the diameter of the portal vein and increase platelet level. Therefore, it is an effective interventional method for the treatment of portal hypertension hemorrhage in liver cirrhosis.
RESUMEN
Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
RESUMEN
ObjectiveTo investigate the influencing factors for overt hepatic encephalopathy (OHE) in patients with hepatitis B cirrhosis after transjugular intrahepatic portosystemic shunt (TIPS), and to construct an individualized risk prediction model. MethodsA total of 302 patients with hepatitis B cirrhosis who underwent TIPS in Department of Gastroenterology, The General Hospital of Western Theater Command, from January 2017 to December 2021 were enrolled, and according to the presence or absence of OHE after surgery, they were divided into non-OHE group with 237 patients and OHE group with 65 patients. The two groups were compared in terms of general data, laboratory markers, Child-Turcotte-Pugh (CTP) score, MELD combined with serum sodium concentration (MELD-Na) score, and albumin-bilirubin (ALBI) score before surgery. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The univariate and multivariate logistic regression analyses were used to identify the influencing factors for OHE after TIPS in patients with hepatitis B cirrhosis, and independent influencing factors were used to construct a nomogram model. The receiver operating characteristic (ROC) curve analysis and the calibration curve analysis were used to evaluate the discriminatory ability and calibration of the model, and the decision curve analysis and the clinical impact curve (CIC) were used to evaluate the clinical effectiveness of the model . ResultsAge (odds ratio [OR]=1.035, 95% confidence interval [CI]: 1.004 — 1.066, P<0.05), white blood cell count (WBC)/platelet count (PLT) ratio (OR=33.725, 95%CI: 1.220 — 932.377, P<0.05), international normalized ratio (INR) (OR=5.149, 95%CI: 1.052 — 25.207, P<0.05), and pre-albumin (PAB) (OR=0.992, 95%CI: 0.983 — 1.000, P<0.05) were independent predictive factors for OHE after TIPS in patients with hepatitis B cirrhosis. The nomogram model constructed based on age, WBC/PLT ratio, INR, and PAB had an area under the ROC curve of 0.716 (95%CI: 0.649 — 0.781), with a sensitivity of 78.5% and a specificity of 56.1%. ConclusionThe nomogram model constructed based on age, WBC/PLT ratio, INR, and PAB can help to predict the risk of OHE after TIPS in patients with hepatitis B cirrhosis.
RESUMEN
BACKGROUND: Spleen stiffness measurement (SSM) performed by transient elastography at 100 Hz is a novel technology for the evaluation of portal hypertension in advanced chronic liver disease, but technical aspects are lacking. We aimed to evaluate the intraexamination variability of SSM and to determine the best transient elastography protocol for obtaining robust measurements to be used in clinical practice. METHODS: We analyzed 253 SSM exams with up to 20 scans for each examination, performed between April 2021 and June 2022. All SSM results were evaluated according to different protocols by dividing data into groups of n measurements (from 2 to 19). Considering as reference the median SSM values across all the 20 measurements, we calculated the distribution of the absolute deviations of each protocol from the reference median. This analysis was repeated 1,000 times by resampling the data. Distributions were also stratified by etiology (chronic liver disease versus clinically significant portal hypertension) and different SSM ranges: < 25 kPa, 25-75, and > 75 kPa. RESULTS: Overall, we observed that the spleen stiffness exam had less variability if it exceeded 12 measurements, i.e., absolute deviations ≤ 5 kPa at 95% confidence. For exams with higher SSM values (> 75 kPa), as seen in clinically significant portal hypertension, at least 15 measurements are highly recommendable. CONCLUSIONS: Fifteen scans per examination should be considered for each SSM exam performed at 100 Hz to achieve a low intraexamination variability within a reasonable time in clinical practice. RELEVANCE STATEMENT: Performing at least 15 scans per examination is recommended for 100 Hz SSM in order to achieve a low intraexamination variability, in particular for values > 75 kPa compatible with clinically significant portal hypertension. KEY POINTS: ⢠Spleen stiffness measurement by transient elastography is used for stratification in patients with portal hypertension. ⢠At 100 Hz, this method may have intraexamination variability. ⢠A minimum of 15 scans per examination achieves a low intraexamination variability.

OBJECTIVES: The study of postoperative liver decompensation after microwave ablation (MWA) for hepatocellular carcinoma (HCC) in patients with clinically significant portal hypertension (CSPH) is still lacking. The purpose of the present study was to compare the postoperative liver decompensation after MWA and laparoscopic resection (LR) for HCC in patients with CSPH. METHODS: The present retrospective study enrolled 222 HCC patients with CSPH who underwent MWA (n = 67) or LR (n = 155). Postoperative liver decompensation, complications, postoperative hospital stays, and overall survival were analyzed. Factors associated with postoperative liver decompensation were identified. RESULTS: After propensity score matching, the postoperative liver decompensation rate was significantly lower in the MWA group than that in the LR group (15.5% versus 32.8%, p = 0.030). The multivariable regression analysis identified that type of treatment (MWA vs. LR, odds ratio [OR] 0.44; 95% confidence interval [CI], 0.21-0.91; p = 0.026) and Child-Pugh B (OR, 2.86; 95% CI, 1.24-6.61; p = 0.014) were independent predictors for postoperative liver decompensation. The rate of complications for patients in the MWA group was significantly lower than that in the LR group (p < 0.001). And MWA showed shorter postoperative hospital stays than LR (3 days vs. 6 days, p < 0.001). Overall survival rate between the two groups was not significantly different (p = 0.163). CONCLUSION: Compared with laparoscopic resection, microwave ablation has a lower rate of postoperative liver decompensation and might be a better option for HCC patients with CSPH. CLINICAL RELEVANCE STATEMENT: Microwave ablation exhibited a lower incidence of postoperative liver decompensation in comparison to laparoscopic resection, thereby conferring greater advantages to hepatocellular carcinoma patients with clinically significant portal hypertension. KEY POINTS: â¢Postoperative liver decompensation rate after microwave ablation was lower than that of laparoscopic resection for hepatocellular carcinoma in patients with clinically significant portal hypertension. â¢Microwave ablation showed shorter postoperative hospital stays than laparoscopic resection. â¢Microwave ablation had fewer complications than laparoscopic resection.
RESUMEN
La colangiopatía portal hace referencia a anomalías colangiográficas que se producen en pacientes con cavernomatosis portal, siendo progresiva, cursando con enfermedad biliar sintomática y anomalías graves de las vías biliares. Y, representa una complicación infrecuente de la hipertensión portal. Se describe el caso de un hombre de 53 años, con historia de larga data de hipertensión portal nocirrótica y cavernomatosis portal, quien presentó un episodio de enfermedad biliar obstructiva sintomática, y en estudios se documentó tejido fibrótico de extensión periportal ascendente con compresión extrínseca del colédoco distal y dilatación de la vía biliar extra e intrahepática. Por lo que se procedió a colangiopancreatografía retrógrada endoscópica, realizándose tratamiento paliativo, con papilotomía pequeña y colocación de endoprótesis biliar plástica, siendo exitoso por ausencia de complicaciones procedimentales, y mejoría clínica y parámetros bioquímicos. Finalmente, recibiendo de alta con indicación de seguimiento prioritario para recambios periódicos de endoprótesis biliares, y valoración por hepatología. La colangiopatía portal es una entidad rara que debe sospecharse en sujetos con hipertensión portal de origen no-cirrótico, con hallazgos imagenológicos de estenosis, angulaciones o dilataciones segmentarias, su tratamiento debe ser individualizado, y la terapia endoscópica es de elección en enfermedad biliar sintomática.
Portal cholangiopathy refers to cholangiographic abnormalities occurring in patients with portal cavernomatosis, being progressive, presenting with symptomatic biliary disease and severe biliary tract abnormalities. And, it represents an infrequent complication of portal hypertension. We describe the case of a 53-year-old man with a long history of non-cirrhotic portal hypertension and portal cavernomatosis, who presented an episode of symptomatic obstructive biliary disease, and studies documented fibrotic tissue of ascending periportal extension with extrinsic compression of the distal common bile duct and dilatation of the extra and intrahepatic biliary tract. Therefore, endoscopic retrograde cholangiopancreatography was performed, and palliative treatment with small papillotomy and placement of a plastic biliary endoprosthesis was successful due to the absence of procedural complications, and clinical improvement and biochemical parameters. Finally, the patient was discharged with indication of priority follow-up for periodic replacement of biliary stents, and evaluation by hepatology. Portal cholangiopathy is a rare entity that should be suspected in subjects with portal hypertension of non-cirrhotic origin, with imaging findings of stenosis, angulations or segmental dilatations, its treatment should be individualized, and endoscopic therapy is of choice in symptomatic biliary disease.
RESUMEN
OBJECTIVE: For transjugular intrahepatic portosystemic shunt (TIPS) creation, ultrasound guidance for portal vein puncture is strongly recommended. However, outside regular hours of service, a skilled sonographer might be lacking. Hybrid intervention suites combine CT imaging with conventional angiography allowing to project 3D information into the conventional 2D imaging and further CT-fluoroscopic puncture of the portal vein. The purpose of this study was to assess whether TIPS using angio-CT facilitates the procedure for a single interventional radiologist. METHODS: All TIPS procedures from 2021 and 2022 which took place outside regular working hours were included (n = 20). Ten TIPS procedures were performed with just fluoroscopy guidance and ten procedures using angio-CT. For the angio-CT TIPS, a contrast-enhanced CT was performed on the angiography table. From the CT, a 3D volume was created using virtual rendering technique (VRT). The VRT was blended with the conventional angiography image onto the live monitor and used as guidance for the TIPS needle. Fluoroscopy time, area dose product, and interventional time were assessed. RESULTS: Hybrid intervention with angio-CT did lead to a significantly shorter fluoroscopy time and interventional time (p = 0.034 for both). Mean radiation exposure was significantly reduced, too (p = 0.04). Furthermore, the mortality rate was lower in patients who underwent the hybrid TIPS (0% vs 33%). CONCLUSION: TIPS procedure in angio-CT performed by only one interventional radiologist is quicker and reduces radiation exposure for the interventionalist compared to mere fluoroscopy guidance. The results further indicate increased safety using angio-CT. CLINICAL RELEVANCE STATEMENT: This study aimed to evaluate the feasibility of using angio-CT in TIPS procedures during non-standard working hours. Results indicated that the use of angio-CT significantly reduced fluoroscopy time, interventional time, and radiation exposure, while also leading to improved patient outcomes. KEY POINTS: ⢠Image guiding such as ultrasound is recommended for transjugular intrahepatic portosystemic shunt creation but might be not available for emergency cases outside of regular working hours. ⢠Transjugular intrahepatic portosystemic shunt creation using an angio-CT with image fusion is feasible for only one physician under emergency settings and results in lower radiation exposure and faster procedures. ⢠Transjugular intrahepatic portosystemic shunt creation using an angio-CT with image fusion seems to be safer than using mere fluoroscopy guidance.

OBJECTIVES: Hepatic hydrothorax (HH) is a predictor of poor survival in cirrhosis patients. However, whether HH increases the mortality risk of cirrhosis patients treated with transjugular intrahepatic portosystemic shunt (TIPS) is unknown. Our objective was to evaluate the influence of HH on the survival of cirrhosis patients after TIPS. METHODS: Cirrhosis patients with portal hypertension complications were selected from a prospective database of consecutive patients treated with TIPS in Xijing Hospital from January 2015 to June 2021. Cirrhosis patients with HH were treated as the experimental group. A control group of cirrhosis patients without HH was created using propensity score matching. Survival after TIPS and the related risk factors were analysed. RESULTS: There were 1292 cirrhosis patients with portal hypertension complications treated with TIPS, among whom 255 patients had HH. Compared with patients without HH, patients with HH had worse liver function (MELD, 12 vs. 10, p < 0.001), but no difference in survival after TIPS was observed. After propensity score matching, 243 patients with HH and 243 patients without HH were enrolled. There was no difference in cumulative survival between patients with and without HH. Cox regression analysis showed that HH was not associated with survival after TIPS, and main portal vein thrombosis (> 50%) was a prognostic factor of long-term survival after TIPS in cirrhosis patients (hazard ratio, 1.386; 95% CI, 1.030-1.865, p = 0.031). CONCLUSION: Hepatic hydrothorax does not increase the risk of death after TIPS in cirrhosis patients. KEY POINTS: ⢠Hepatic hydrothorax is a decompensated event of cirrhosis and increases the risk of death. ⢠Hepatic hydrothorax is associated with worse liver function. ⢠Hepatic hydrothorax does not increase the mortality of cirrhosis treated with TIPS.

BACKGROUND/AIMS: The utility of Baveno-VII criteria of clinically significant portal hypertension (CSPH) to predict decompensation in compensated advanced chronic liver disease (cACLD) patient needs validation. We aim to validate the performance of CSPH criteria to predict the risk of decompensation in an international real-world cohort of cACLD patients. METHODS: cACLD patients were stratified into three categories (CSPH excluded, grey zone, and CSPH). The risks of decompensation across different CSPH categories were estimated using competing risk regression for clustered data, with death and hepatocellular carcinoma as competing events. The performance of "treating definite CSPH" strategy to prevent decompensation using non-selective beta-blocker (NSBB) was compared against other strategies in decision curve analysis. RESULTS: One thousand one hundred fifty-nine cACLD patients (36.8% had CSPH) were included; 7.2% experienced decompensation over a median follow-up of 40 months. Non-invasive assessment of CSPH predicts a 5-fold higher risk of liver decompensation in cACLD patients (subdistribution hazard ratio, 5.5; 95% confidence interval, 4.0-7.4). "Probable CSPH" is suboptimal to predict decompensation risk in cACLD patients. CSPH exclusion criteria reliably exclude cACLD patients at risk of decompensation, regardless of etiology. Among the grey zone, the decompensation risk was negligible among viral-related cACLD, but was substantially higher among the non-viral cACLD group. Decision curve analysis showed that "treating definite CSPH" strategy is superior to "treating all varices" or "treating probable CSPH" strategy to prevent decompensation using NSBB. CONCLUSION: Non-invasive assessment of CSPH may stratify decompensation risk and the need for NSBB in cACLD patients.

Budd-Chiari syndrome (B-CS) is a rare disease caused by hepatic vein outflow obstruction, and its etiology is complex and inconclusive. Current studies suggest that vascular dysplasia, gut microbiota and trace element imbalance may be related to the pathogenesis of B-CS, and the development of high-throughput sequencing technology may help to clarify the exact pathogenesis of B-CS. The symptoms of B-CS are not specific and rely mainly on imaging methods to establish the diagnosis, so there is an urgent need to find new noninvasive biological diagnostic markers. In addition, there are many pathological types and different criteria of B-CS, which mostly can′t fully reflect the pathophysiological changes of B-CS patients and guide clinical treatment. Therefore, we recommend pathophysiological classification according to the hemodynamic changes and collateral circulation compensation of B-CS, and then develop personalized treatment strategies for stratified management different from the traditional early diagnosis and treatment protocols. This article summarizes and discusses the above contents.
RESUMEN
Objective:To explore the value of a new inflammatory index in predicting portal vein thrombosis in cirrhotic patients with Portal hypertension.Methods:This study was a single center cross-sectional study. The patients with portal hypertension who underwent portal vein computed tomography (CT) examination and hepatic vein pressure gradient (HVPG) measurement in the Minhang District Central Hospital of Shanghai from January 2019 to February 2023 due to cirrhosis were included. They were divided into thrombosis group and non thrombosis group according to whether portal vein thrombosis was combined or not. The predictive value of Monocyte lymphocyte ratio (MLR), neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR) and systemic immune inflammatory index (SII) for portal vein thrombosis was determined by logistic regression analysis and receiver operating characteristic (ROC) curve.Results:A total of 122 patients were ultimately included and were divided into a thrombus group of 20 and a non thrombus group of 102 based on portal vein CT results. The MLR and PLR of patients in the thrombotic group were significantly higher than those in the non thrombotic group ( P=0.038 7, P=0.040 7). There was no significant difference in hemoglobin, platelets, leukocytes, neutrophils, lymphocytes, monocyte, NLR, SII, albumin, alanine aminotransferase (ALT), total bilirubin, creatinine, prothrombin time, D-dimer, and C-reactive protein between the two groups (all P>0.05). The diagnosis model of portal vein thrombosis was constructed by logistic regression model. It was found that the area under the ROC of MLR combined with D-dimer and ascites was 0.900, the sensitivity was 0.850, and the specificity was 0.431. Conclusions:The new inflammatory index (including MLR and PLR) is significantly increased in cirrhotic patients with portal vein thrombosis. MLR combined with D-dimer and ascites can predict portal vein thrombosis in cirrhotic patients.
RESUMEN
Objective:To study the risk factors of early postoperative portal vein thrombosis (PVT) after salvage devascularization for failed endoscopic therapy.Methods:A retrospective analysis was conducted on the clinical data of 525 cirrhotic patients who underwent pericardial devascularization for portal hypertension and esophagogastric variceal bleeding at the Department of General Surgery, Beijing Ditan Hospital, Capital Medical University from January 2012 to January 2022. There were 435 males and 90 females, aged 47(37, 58) years old. These patients were divided into two groups based on whether PVT occurred after devascularization: the PVT group ( n=225) and the non-PVT group ( n=300). Clinical data including gender, age, portal vein diameter and postoperative platelet elevation level (PPEL) were studied and the related factors of PVT were analyzed by univariate analysis. Factors with statistically significant differences were included in logistic regression analysis. Results:Univariate analysis showed that the significant risk factors of PVT were the scores of the model of end-stage liver disease, platelets, portal vein diameter, endoscopic therapy, operation duration, surgical bleeding volume, intraoperative blood transfusion and PPEL on the first and third postoperative days (all P<0.05). Multivariate analysis showed that portal vein diameter ≥13 mm ( OR=6.000, 95% CI: 3.418-10.533), endoscopic injection ( OR=1.894, 95% CI: 1.196-2.998), operation duration ≥ 180 min ( OR=8.520, 95% CI: 5.333-13.554), PPEL ≥ 20×10 9/L on the first postoperative day ( OR=2.125, 95% CI: 1.306-3.456) and PPEL≥50×10 9/L on the third postoperative day ( OR=1.925, 95% CI: 1.192-3.109) increased the risk of PVT (all P<0.05). Conclusion:The diameter of portal vein, endoscopic treatment, operation duration and PPEL on the first and third days after operation were independent risk factors of early postoperative PVT development.
RESUMEN
We wished to summarize the clinical features of common variable immunodeficiency (CVID) complicated by non-cirrhotic portal hypertension (NCPH) and to deepen our understanding of it. The case data of CVID complicated with NCPH admitted to Peking Union Medical College Hospital from January 1983 to May 2021 were analyzed retrospectively to summarize their clinical characteristics. Six patients with CVID combined with NCPH (three of each sex; 16-45 years) were assessed. Four patients had portal hypertension. All patients had anemia, splenomegaly, a normal serum level of albumin and transaminases, and possibly increased levels of alkaline phosphatase and gamma-glutamyl transpeptidase. Two patients were diagnosed with esophagogastric fundic varices by gastroscopy. Two patients underwent splenectomy (which improved hematologic abnormalities partially). Four patients had autoimmune disease. Two cases were diagnosed with nodular regenerative hyperplasia (NRH) upon liver biopsy. Six patients were administered intravenous immunoglobulin-G (0.4-0.6 g/kg bodyweight) once every 3-4 weeks as basic therapy. Often, CVID complicated with NCPH has: (1) The manifestations of portal hypertension as the primary symptom. (2) Autoimmune-related manifestations. Imaging can provide important diagnostic clues. The etiology may be related to hepatic NRH and splenomegaly due to recurrent infections.
RESUMEN
Objective:To evaluate the clinical efficacy of laparoscopic splenectomy and azygoportal disconnection (LSD) with intraoperative endoscopic variceal ligation (LSDL) in the treatment of esophagogastric variceal bleeding (EVR).Method:In this study,90 cirrhotic patients with esophagogastric variceal bleeding (EVB) were divided to receive either LSD ( n=45) or LSDL ( n=45) from Jan 2020 and Dec 2021. Results:There were no significant differences in estimated blood loss, incidence of blood transfusion, time to first flatus, off-bed activity and postoperative hospital stay between the two groups (all P>0.05). Compared with LSD group, operation time was longer in LSDL group[ (140±21) min vs. (150±19) min, t=2.420, P=0.018]. LSDL was associated with significantly decreased EVR rate in one year follow-up (2% vs. 18%, P=0.030). Univariate analysis and multivariate logistic regression revealed that LSDL was a significant independent protective factor for EVR as compared with LSD ( P<0.05). Conclusion:LSDL procedure is not only technically feasible and safe, it also contributed to lower postoperative EVR risk than single LSD.
