Background Endoscopic variceal ligation (EVL) is a widely accepted treatment for esophagogastric varices in patients with portal hypertension. It is used for urgent treatment and prophylactic treatment of esophagogastric varices not only in adults, but also in pediatric patients. However, major life-threatening adverse events such as early rebleeding can occur. Although early rebleeding after EVL among children and adolescents has been reported, the risk factors remain obscure. This study evaluated the risk factors for early rebleeding after EVL in children and adolescents. Methods Subjects were children and adolescents with portal hypertension aged less than 18 years who underwent EVL for esophagogastric varices. Early rebleeding was defined as hematemesis, active bleeding or blood retention in the stomach, confirmed by esophagogastroduodenoscopy from 2 hours to 5 days after EVL. Results A total of 50 EVL sessions on 22 patients were eligible for this study. There were 4 episodes of early rebleeding. No other major adverse events have occurred. Multivariate analysis showed that EVL implemented at cardiac varices just below the esophagogastric junction (EGJ); within 5mm from the EGJ, is the independent factor of higher risk of early rebleeding: odds ratio 18.2 (95% Confidence interval: 1.40-237.0), p=0.02. Conclusions Children and adolescents who undergo EVL for cardiac varices just below the EGJ have a higher risk of early rebleeding than those who do not.

Background and Aim Gastric antral vascular ectasia (GAVE) is observed in patients with liver cirrhosis and portal hypertension. The exact pathophysiologic mechanism that underlies this condition is unknown. In our study, we estimate the prevalence of GAVE in hepatitis C virus (HCV) cirrhosis and attempted to determine if any of the hepatocellular manifestations, liver functions, serum gastrin, abdominal ultrasound and endoscopic picture have a relation to, or could predict, the occurrence of GAVE in cirrhotic patients. Methods This study includes 500 HCV‐related liver cirrhosis patients. According to endoscopic assessment, we detected 30 patients with GAVE (Group 2). From the 470 patients without GAVE, we randomly selected 120 patients (Group 1), to avoid statistical bias, for comparison with Group 2. Comparison included clinical manifestations, laboratory findings, serum gastrin, ultrasound findings, and endoscopic findings (esophageal and/or gastric varices and gastropathy). Results The percentage of GAVE in HCV‐related liver cirrhosis is 0.06%. We can predict GAVE by platelets, palmer erythema, diabetes mellitus (DM), marked ascites > with area under the curve of 0.67, 75.5, 0.62, and 0.40%, and accuracy of 82.5, 72, 70.7, and 79.3%, respectively. There was no correlation found between occurrence of GAVE and endoscopic findings. Also, there was no correlation found between occurrence of GAVE and serum gastrin levels, which reflect another pathophysiology, and we found no statistically significant correlation with GAVE. Conclusions Palmer erythema, low platelets, DM, and ascites might help in the prediction of GAVE. GAVE is not linked to the presence, type or grade of varices, and gastropathy., The percentage of gastric antral vascular ectasia (GAVE) in hepatitis C virus‐related liver cirrhosis is 0.06%. Palmer erythema, low platelets, diabetes mellitus, and ascites might help in the prediction of GAVE. GAVE is not linked to the presence, type or grade of varices, and gastropathy.

Rhythm control strategies in patients with esophageal varices and atrial arrhythmias pose a unique challenge. The left atrium should be imaged for a thrombus prior to attempting cardioversion or ablation, but the presence of varices is a relative contraindication for transesophageal echocardiography. We present a safe, novel technique of evaluating for left atrial thrombus with simultaneous transesophageal echocardiography and esophagogastroduodenoscopy using slim probes in a patient with large, high-risk esophageal varices, and symptomatic atrial flutter with rapid ventricular rates despite medical therapy.

Despite scant evidence, current guidelines indicate that esophageal varices are a relative contraindication to transesophageal echocardiography (TEE). The aim of this study is to compare the risk of gastrointestinal bleeding following TEE among cirrhotic patients with and without endoscopically-documented esophageal varices. This is a retrospective analysis of patients with cirrhosis who underwent upper endoscopy within 4 years of TEE at five institutions between January 2000 and March 2020. Primary outcome was overt gastrointestinal bleeding. Secondary outcomes were hemoglobin decline by at least 2 g/dL or blood transfusion within 48 hours following TEE. Of the 191 patients, 79 (41.4%) had esophageal varices (30.4% large). No patient experienced a primary outcome. Secondary outcomes occurred in 52 (27.2%): 28 (35.4%) with esophageal varices and 24 (21.4%) without varices. After propensity-score covariate adjustment, the odds ratio for a secondary outcome in patients with esophageal varices was 1.49 (95% confidence interval 0.74-2.99). Restricting analysis to those who underwent endoscopy within 1 year of TEE did not significantly alter results. The risk of a secondary outcome was identical between patients who had upper endoscopy prior (27.5%) versus subsequent (26.7%; P = 1.00) to TEE. Conclusions: Among patients with cirrhosis, there was no overt gastrointestinal bleeding after TEE. The likelihood of a 2 g/dL decline in hemoglobin or blood transfusion within 48 hours following TEE was not significantly higher in patients with esophageal varices after controlling for confounders. Patients who underwent upper endoscopy before TEE did not manifest a lower risk of secondary outcomes versus those who had endoscopy after TEE, suggesting that routine preprocedural endoscopy is of marginal utility.

BACKGROUND AND AIM Gastroesophageal varices (GEV) present in compensated advanced chronic liver disease (cACLD) and can develop into high-risk varices (HRV). The gold standard for diagnosing GEV is esophagogastroduodenoscopy (EGD). However, EGD is invasive and less tolerant. This study aimed to develop and validate radiomics signatures based on noncontrast-enhanced computed tomography (CT) images for non-invasive diagnosis of GEV and HRV in patients with cACLD. METHODS The multicenter trial enrolled 161 patients with cACLD from six university hospitals in China between January 2015 and September 2019, who underwent both EGD and noncontrast-enhanced CT examination within 14 days prior to the endoscopy. Two radiomics signatures, termed rGEV and rHRV, respectively, were built based on CT images in a training cohort of 129 patients and validated in a prospective validation cohort of 32 patients (ClinicalTrials. gov identifier: NCT03749954). RESULTS In the training cohort, both rGEV and rHRV exhibited high discriminative abilities on determining the existence of GEV and HRV with the area under receiver operating characteristic curve (AUC) of 0.941 (95% confidence interval [CI] 0.904-0.978) and 0.836 (95% CI 0.766-0.905), respectively. In validation cohort, rGEV and rHRV showed high discriminative abilities with AUCs of 0.871 (95% CI 0.739-1.000) and 0.831 (95% CI 0.685-0.978), respectively. CONCLUSIONS This study demonstrated that rGEV and rHRV could serve as the satisfying auxiliary parameters for detection of GEV and HRV with good diagnostic performance.

Background and Aim Hepatic venous pressure gradient (HVPG), although an important determinant in predicting rebleeding after an episode of acute variceal bleed (AVB), is seldom utilized in clinical practice. We aimed to study the role of liver stiffness measurement (LSM) after variceal bleeding as a potential noninvasive predictor of rebleed. Methods This was a post hoc analysis of clinical trial of patients undergoing HVPG (postbleed HVPG) and LSM (postbleed LSM) assessment within 3–5 days of index AVB. HVPG response was assessed after 4 weeks of pharmacotherapy. Comparative assessment of long‐term rebleeding rates stratified using postbleed LSM, postbleed HVPG, and HVPG response was performed. Decision curve analysis (DCA) was conducted to identify the most appropriate tool for routine use. Results Long‐term clinical and HVPG response data were available for 48 patients post‐AVB, of whom 45 patients had valid postbleed LSM. Rebleeding occurred in 13 (28%) patients over a median follow‐up of 4 years with no early rebleeds. Postbleed LSM >30 kPa and baseline HVPG >15 mm Hg were optimal cutoffs for identifying patients at high risk of rebleeding. Time‐dependent receiver operating characteristic curves and competing risk analysis accounting for death showed similar discriminative values for all three stratification tools. At usual risk thresholds, HVPG response had maximum benefit on DCA followed by postbleed LSM. On DCA, 50–60 additional HVPGs were required to detect one additional patient at high risk of rebleed. Conclusion Liver stiffness measurement during AVB can potentially be used as an alternative to portal pressure indices in decompensated cirrhosis to identify those at high risk of late‐onset rebleed., Liver stiffness measure during the period of acute variceal bleeding predicted rebleeding comparable to hepatic venous pressure gradient measurement and its subsequent response.

Background and aim Secondary prophylaxis (SP) of variceal rebleeding was reported to improve outcomes of hepatocellular carcinoma (HCC) patients, but the optimal endoscopic approach is not well defined. We compared outcomes in HCC patients who underwent SP by endoscopic ultrasound-guided cyanoacrylate obturation (EUS-CYA) versus no SP. Methods Between 2014 and 2018, 30 consecutive patients with inoperable HCC and recent endoscopically controlled variceal bleeding were prospectively recruited. Twenty-seven patients with persistent varices ≥ 3 mm on endoscopic ultrasound underwent EUS-CYA for SP. Thirty-three HCC patients treated by esophagogastroduodenoscopy-guided CYA obturation (EGD-CYA) alone for acute variceal bleeding between 2009 and 2013 were identified from a prospective gastrointestinal bleed registry as standard of care controls for comparison. Outcome measures were death-adjusted cumulative incidence of rebleeding, bleeding-free survival, technical success, and procedure-related adverse events of EUS-CYA. Results The majority of patients in both groups had advanced HCC, portal vein thrombosis, and Child-Pugh B cirrhosis. EUS-CYA was successful in all 27 patients with no radiographic evidence of cyanoacrylate-lipiodol embolization. Significantly lower 30- and 90-day death-adjusted cumulative incidence of rebleeding (14.8% vs 42.4%, P = 0.023 and 18.5% vs 60.6%, P = 0.002, respectively) and significantly higher variceal bleeding-free survival at 3 and 6 months (51.9% vs 21.2%, P = 0.009, 40.7% vs 15.2%, P = 0.010, respectively) were observed in the EUS-CYA group when compared with standard of care group. Conclusions Secondary prophylaxis by EUS-CYA reduced rebleeding rate and improved variceal bleeding-free survival in patients with inoperable HCC and variceal bleeding when compared with no SP. Randomized studies are needed to confirm the benefits of EUS-CYA for this difficult-to-treat population.

Background & aims The American Association for the Study of Liver Diseases recommends the use of a 2-grade classification system (small and large) to describe the size of oesophageal varices (OV). Data on observer agreement (OA) on this system are currently lacking. We aimed to evaluate this classification and compare it to the widely used 3-grade classification (grade 1 'small', grade 2 'medium', grade 3 'large') among operators of variable experience. Methods High-definition video recordings of 100 patients with cirrhosis were prospectively collected using standardised criteria. Nine observers of variable experience performed independent evaluations of the videos in random order. OV were scored using both systems. All assessments were repeated a year later by the same observers to assess intra-observer agreement. Results Interobserver agreement (all observers) using the 2-grade and the 3-grade system was k = 0.71 (95% CI: 0.64-0.78) and k = 0.73 (95% CI: 0.66-0.79) respectively. When using the 2-grade system, intra-observer agreement between hepatologists (n = 3), luminal gastroenterologists (n = 3) and trainee gastroenterologists (n = 3) was k = 0.89 (95% CI: 0.86-0.91), k = 0.72 (95% CI: 0.67-0.77), and k = 0.74 (95% CI: 0.67-0.8) respectively. With the 3-grade system; intra-observer agreement between the same three subgroups were k = 0.9 (95% CI: 0.87-0.92), k = 0.73 (95% CI: 0.68-0.78), k = 0.77 (95% CI: 0.71-0.82) respectively. Conclusions There was no difference in OA between the 2-grade and 3-grade classification systems. Hepatologists had significantly higher levels of consistency in grading OV. This may have implications to create alternative training models for residents and fellows in the recognition and grading of OV.

Aim Esophagogastric variceal hemorrhage is a cause of poor prognosis in patients with biliary atresia (BA). To prevent variceal hemorrhage, simple and reliable screening methods for high-risk esophagogastric varices (HR-EGV) are needed. We evaluated the efficacy of liver stiffness (LS) and spleen stiffness (SS) as measured by 2-D shear wave elastography (2D-SWE), which was reported to be more accurate than transient elastography, for detecting HR-EGV in children with BA. Methods Thirty-four children with BA were enrolled. Both LS and SS were measured by 2D-SWE. The presence of large esophageal varices or esophageal varices of any size with red wale marking and/or the presence of gastric varices along the cardia were defined as HR-EGV. Clinical data were collected and previously reported prediction indices for varices were calculated. Results Liver stiffness and SS were obtained from all patients. Fourteen patients showed HR-EGV. Significantly different variables between patients with and without HR-EGV were as follows: spleen diameter (116 mm vs. 95 mm), clinical prediction rule (104.7 vs. 124.7), King's variceal prediction score (78.8 vs. 99.4), aspartic aminotransferase-to-platelet ratio index (2.03 vs. 0.98), LS (2.63 m/s vs. 1.87 m/s), and SS (4.44 m/s vs. 3.69 m/s). The highest area under the receiver operating characteristic curve for detecting HR-EGV was that for SS (0.900), and the cut-off SS of 4.12 m/s yielded 92.9% sensitivity and 90% specificity. The intraclass correlation coefficient for intra-observer reproducibility was 0.828. Conclusions Spleen stiffness from 2D-SWE offered the most accurate predictor of HR-EGV in BA children.

BACKGROUND Nonmalignant portal vein thrombosis is a significant event in the course of cirrhosis that can contraindicate liver transplantation and even impact survival after the surgical procedure. Risk factors are not completely known or validated and are still debated. AIM To identify in patients with cirrhosis the risk factors for portal vein thrombosis that are assessable in clinical practice. METHODS Between January 2014 and February 2017, 108 outpatients with cirrhosis and no portal vein thrombosis (78% Child A) were enrolled. Doppler ultrasound was performed every 3 or 6 months, for a median follow up of 19 months. RESULTS Portal vein thrombosis developed in 11 patients. Nonselective beta-blockade (hazard ratio [HR] 10.56; 95% confidence interval [CI]: 1.35-82.73; P = 0.025), and medium or large-sized oesophageal varices (HR 5.67; 95% CI: 1.49-21.63; P = 0.011) at baseline were associated with portal vein thrombosis development. Although heart rate (P

Aims The liver function of patients with hepatitis C virus (HCV) infection who obtained sustained virologic response (SVR) has been known to improve after HCV eradication. However, a predictor of liver function after SVR has not been definitively identified. The aim of this retrospective study was to identify a predictor of deteriorated liver function and Fibrosis-4 (FIB-4) index after SVR was achieved by direct-acting antiviral (DAA) treatment. Methods This study retrospectively enrolled 248 patients who obtained SVR by DAA treatment. None of the patients developed hepatocellular carcinoma during this study. Liver function was assessed at the end of treatment (EOT) and at 24, 48, 72, and 96 weeks after EOT. Results At 96 weeks after EOT, the serum aspartate aminotransferase and alanine aminotransferase levels were significantly decreased from those at EOT. The platelet count was significantly increased from 14.9 × 104 /μL at EOT to 17.1 × 104 /μL at 96 weeks after EOT. Ten patients showed an increased FIB-4 (>1.00) index. Multivariate analysis with 171 patients who underwent endoscopic assessment revealed that the presence of varices was an independent predictor of deterioration in the FIB-4 index (odds ratio, 5.56; P = 0.041). Conclusion Most of the study patients who obtained SVR showed improved liver function after EOT. Patients without increasing platelet counts after SVR due to DAA therapy should be evaluated for complications induced by portal hypertension.

Background Total pancreatectomy may be necessary to achieve margin-negative resection for pancreatic cancer. However, despite the desirability of saving the spleen, the feasibility, safety, and oncological outcomes of spleen-preserving total pancreatectomy have not been studied in patients with malignancy involving the pancreatic neck or proximal body. The aim of this study was to report the efficacy of spleen-preserving total pancreatectomy using the Warshaw technique for patients with pancreatic malignancies. Methods A retrospective analysis of patients who underwent total pancreatectomy for malignant pancreatic diseases between December 2006 and January 2018 focused on comparing the clinical outcomes between conventional operations with splenectomy and spleen-preserving total pancreatectomy using the Warshaw technique. Results Thirty-eight patients among a total of 59 total pancreatectomies had the spleen preservation by the Warshaw operation. In this series, the pancreatic ductal adenocarcinomas resected with the Warshaw technique were of smaller tumor size but had greater rates of vascular invasion, resulting in the more frequent vascular resection. No patients had splenic complications requiring splenectomy, but two patients intended to have the Warshaw operation were converted to splenectomy because of splenic malperfusion. Asymptomatic perigastric varices were noted in 4 patients. Postoperative morbidity and mortality were comparable between the Warshaw and conventional operation groups. Recurrence-free and overall survival was similar in both groups. Conclusion In patients with pancreatic malignancy, total pancreatectomy with preservation of the spleen using the Warshaw technique achieves outcomes comparable with conventional total pancreatectomy with splenectomy in selected patients.

OBJECTIVES To analyze the clinical significance of using hepatic transit time (HTT) to evaluate portal vein pressure in gastroesophageal varices patients. METHODS For the observation group, we enrolled 50 gastroesophageal varices patients who had received esophagogastric variceal embolization in our hospital between January 2015 and February 2018. Patients without liver disease populated the control group and were recruited during the same time period. All patients underwent contrast-enhanced sonography. In the observation group, free portal pressure (FPP) was detected during esophagogastric variceal embolization with ultrasound guidance. Differences in hepatic artery-hepatic vein transit time (HA-HVTT), portal vein-hepatic vein transit time (PV-HVTT), and parenchyma-hepatic vein transit time (PA-HVTT) were compared between groups. Correlations between HA-HVTT, PV-HVTT, PA-HVTT, and FPP in the observation group were analyzed using the Pearson coefficient and linear regression analysis. RESULTS HA-HVTT (t = 5.078; P

Objectives To review available information regarding in-office procedures for benign vocal fold lesions (BVFL). Methods PubMed term search on office/awake laryngeal procedures for any of the following specific lesions: Reinke's edema (RE), polyps, nodules, varices, vocal process granuloma, and vocal fold (VF) scar. Results In-office ablative and nonablative laser procedures have been described for BVFL, including RE, polyps, varices, and granuloma. Fiber-based lasers used include potassium titanyl phosphate, pulsed dye laser, and more recently CO2 . In-office intralesional steroid injection (ISI) for BVFL targets the inflammatory process involved with the lesion and may induce regression of polyps, nodules, RE, and granuloma. Botulinum toxin-induced "voice rest" has been described as adjunctive treatment for refractory VF nodules or vocal process granuloma. Most in-office techniques for treating BVFL rely on induction of lesion regression rather than complete lesion removal, as in conventional operative microsurgery. When treating VF scarring, in-office procedures aim to alter the wound-healing process; ISI targets the inflammatory phase and angiolytic lasers target the proliferative phase. Conclusion In-office procedures for BVFL apply new technology that can potentially lower risk and cost. Although numerous case series have shown the potential of these procedures, data that thoroughly compares outcomes with those of microlaryngoscopic techniques is needed.

Background Approximately 40% to 95% of people with liver cirrhosis have oesophageal varices. About 15% to 20% of oesophageal varices bleed within about one to three years after diagnosis. Several different treatments are available, including, among others, endoscopic sclerotherapy, variceal band ligation, somatostatin analogues, vasopressin analogues, and balloon tamponade. However, there is uncertainty surrounding the individual and relative benefits and harms of these treatments. Objectives To compare the benefits and harms of different initial treatments for variceal bleeding from oesophageal varices in adults with decompensated liver cirrhosis, through a network meta-analysis; and to generate rankings of the different treatments for acute bleeding oesophageal varices, according to their benefits and harms. Search methods We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers until 17 December 2019, to identify randomised clinical trials (RCTs) in people with cirrhosis and acute bleeding from oesophageal varices. Selection criteria We included only RCTs (irrespective of language, blinding, or status) in adults with cirrhosis and acutely bleeding oesophageal varices. We excluded RCTs in which participants had bleeding only from gastric varices, those who failed previous treatment (refractory bleeding), those in whom initial haemostasis was achieved before inclusion into the trial, and those who had previously undergone liver transplantation. Data collection and analysis We performed a network meta-analysis with OpenBUGS software, using Bayesian methods, and calculated the differences in treatments using odds ratios (OR) and rate ratios with 95% credible intervals (CrI) based on an available-case analysis, according to National Institute of Health and Care Excellence Decision Support Unit guidance. We performed also the direct comparisons from RCTs using the same codes and the same technical details. Main results We included a total of 52 RCTs (4580 participants) in the review. Forty-eight trials (4042 participants) were included in one or more comparisons in the review. The trials that provided the information included people with cirrhosis due to varied aetiologies and those with and without a previous history of bleeding. We included outcomes assessed up to six weeks. All trials were at high risk of bias. A total of 19 interventions were compared in the trials (sclerotherapy, somatostatin analogues, vasopressin analogues, sclerotherapy plus somatostatin analogues, variceal band ligation, balloon tamponade, somatostatin analogues plus variceal band ligation, nitrates plus vasopressin analogues, no active intervention, sclerotherapy plus variceal band ligation, balloon tamponade plus sclerotherapy, balloon tamponade plus somatostatin analogues, balloon tamponade plus vasopressin analogues, variceal band ligation plus vasopressin analogues, balloon tamponade plus nitrates plus vasopressin analogues, balloon tamponade plus variceal band ligation, portocaval shunt, sclerotherapy plus transjugular intrahepatic portosystemic shunt (TIPS), and sclerotherapy plus vasopressin analogues). We have reported the effect estimates for the primary and secondary outcomes when there was evidence of differences between the interventions against the reference treatment of sclerotherapy, but reported the other results of the primary and secondary outcomes versus the reference treatment of sclerotherapy without the effect estimates when there was no evidence of differences in order to provide a concise summary of the results. Overall, 15.8% of the trial participants who received the reference treatment of sclerotherapy (chosen because this was the commonest treatment compared in the trials) died during the follow-up periods, which ranged from three days to six weeks. Based on moderate-certainty evidence, somatostatin analogues alone had higher mortality than sclerotherapy (OR 1.57, 95% CrI 1.04 to 2.41; network estimate; direct comparison: 4 trials; 353 participants) and vasopressin analogues alone had higher mortality than sclerotherapy (OR 1.70, 95% CrI 1.13 to 2.62; network estimate; direct comparison: 2 trials; 438 participants). None of the trials reported health-related quality of life. Based on low-certainty evidence, a higher proportion of people receiving balloon tamponade plus sclerotherapy had more serious adverse events than those receiving only sclerotherapy (OR 4.23, 95% CrI 1.22 to 17.80; direct estimate; 1 RCT; 60 participants). Based on moderate-certainty evidence, people receiving vasopressin analogues alone and those receiving variceal band ligation had fewer adverse events than those receiving only sclerotherapy (rate ratio 0.59, 95% CrI 0.35 to 0.96; network estimate; direct comparison: 1 RCT; 219 participants; and rate ratio 0.40, 95% CrI 0.21 to 0.74; network estimate; direct comparison: 1 RCT; 77 participants; respectively). Based on low-certainty evidence, the proportion of people who developed symptomatic rebleed was smaller in people who received sclerotherapy plus somatostatin analogues than those receiving only sclerotherapy (OR 0.21, 95% CrI 0.03 to 0.94; direct estimate; 1 RCT; 105 participants). The evidence suggests considerable uncertainty about the effect of the interventions in the remaining comparisons where sclerotherapy was the control intervention. Authors' conclusions Based on moderate-certainty evidence, somatostatin analogues alone and vasopressin analogues alone (with supportive therapy) probably result in increased mortality, compared to endoscopic sclerotherapy. Based on moderate-certainty evidence, vasopressin analogues alone and band ligation alone probably result in fewer adverse events compared to endoscopic sclerotherapy. Based on low-certainty evidence, balloon tamponade plus sclerotherapy may result in large increases in serious adverse events compared to sclerotherapy. Based on low-certainty evidence, sclerotherapy plus somatostatin analogues may result in large decreases in symptomatic rebleed compared to sclerotherapy. In the remaining comparisons, the evidence indicates considerable uncertainty about the effects of the interventions, compared to sclerotherapy.

Background Approximately 40% to 95% of people with cirrhosis have oesophageal varices. About 15% to 20% of oesophageal varices bleed in about one to three years of diagnosis. Several different treatments are available, which include endoscopic sclerotherapy, variceal band ligation, beta-blockers, transjugular intrahepatic portosystemic shunt (TIPS), and surgical portocaval shunts, among others. However, there is uncertainty surrounding their individual and relative benefits and harms. Objectives To compare the benefits and harms of different initial treatments for secondary prevention of variceal bleeding in adults with previous oesophageal variceal bleeding due to decompensated liver cirrhosis through a network meta-analysis and to generate rankings of the different treatments for secondary prevention according to their safety and efficacy. Search methods We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and trials registers until December 2019 to identify randomised clinical trials in people with cirrhosis and a previous history of bleeding from oesophageal varices. Selection criteria We included only randomised clinical trials (irrespective of language, blinding, or status) in adults with cirrhosis and previous history of bleeding from oesophageal varices. We excluded randomised clinical trials in which participants had no previous history of bleeding from oesophageal varices, previous history of bleeding only from gastric varices, those who failed previous treatment (refractory bleeding), those who had acute bleeding at the time of treatment, and those who had previously undergone liver transplantation. Data collection and analysis We performed a network meta-analysis with OpenBUGS using Bayesian methods and calculated the differences in treatments using hazard ratios (HR), odds ratios (OR) and rate ratios with 95% credible intervals (CrI) based on an available-case analysis, according to National Institute of Health and Care Excellence Decision Support Unit guidance. Main results We included a total of 48 randomised clinical trials (3526 participants) in the review. Forty-six trials (3442 participants) were included in one or more comparisons. The trials that provided the information included people with cirrhosis due to varied aetiologies. The follow-up ranged from two months to 61 months. All the trials were at high risk of bias. A total of 12 interventions were compared in these trials (sclerotherapy, beta-blockers, variceal band ligation, beta-blockers plus sclerotherapy, no active intervention, TIPS (transjugular intrahepatic portosystemic shunt), beta-blockers plus nitrates, portocaval shunt, sclerotherapy plus variceal band ligation, beta-blockers plus nitrates plus variceal band ligation, beta-blockers plus variceal band ligation, sclerotherapy plus nitrates). Overall, 22.5% of the trial participants who received the reference treatment (chosen because this was the commonest treatment compared in the trials) of sclerotherapy died during the follow-up period ranging from two months to 61 months. There was considerable uncertainty in the effects of interventions on mortality. Accordingly, none of the interventions showed superiority over another. None of the trials reported health-related quality of life. Based on low-certainty evidence, variceal band ligation may result in fewer serious adverse events (number of people) than sclerotherapy (OR 0.19; 95% CrI 0.06 to 0.54; 1 trial; 100 participants). Based on low or very low-certainty evidence, the adverse events (number of participants) and adverse events (number of events) may be different across many comparisons; however, these differences are due to very small trials at high risk of bias showing large differences in some comparisons leading to many differences despite absence of direct evidence. Based on low-certainty evidence, TIPS may result in large decrease in symptomatic rebleed than variceal band ligation (HR 0.12; 95% CrI 0.03 to 0.41; 1 trial; 58 participants). Based on moderate-certainty evidence, any variceal rebleed was probably lower in sclerotherapy than in no active intervention (HR 0.62; 95% CrI 0.35 to 0.99, direct comparison HR 0.66; 95% CrI 0.11 to 3.13; 3 trials; 296 participants), beta-blockers plus sclerotherapy than sclerotherapy alone (HR 0.60; 95% CrI 0.37 to 0.95; direct comparison HR 0.50; 95% CrI 0.07 to 2.96; 4 trials; 231 participants); TIPS than sclerotherapy (HR 0.18; 95% CrI 0.08 to 0.38; direct comparison HR 0.22; 95% CrI 0.01 to 7.51; 2 trials; 109 participants), and in portocaval shunt than sclerotherapy (HR 0.21; 95% CrI 0.05 to 0.77; no direct comparison) groups. Based on low-certainty evidence, beta-blockers alone and TIPS might result in more, other compensation, events than sclerotherapy (rate ratio 2.37; 95% CrI 1.35 to 4.67; 1 trial; 65 participants and rate ratio 2.30; 95% CrI 1.20 to 4.65; 2 trials; 109 participants; low-certainty evidence). The evidence indicates considerable uncertainty about the effect of the interventions including those related to beta-blockers plus variceal band ligation in the remaining comparisons. Authors' conclusions The evidence indicates considerable uncertainty about the effect of the interventions on mortality. Variceal band ligation might result in fewer serious adverse events than sclerotherapy. TIPS might result in a large decrease in symptomatic rebleed than variceal band ligation. Sclerotherapy probably results in fewer 'any' variceal rebleeding than no active intervention. Beta-blockers plus sclerotherapy and TIPS probably result in fewer 'any' variceal rebleeding than sclerotherapy. Beta-blockers alone and TIPS might result in more other compensation events than sclerotherapy. The evidence indicates considerable uncertainty about the effect of the interventions in the remaining comparisons. Accordingly, high-quality randomised comparative clinical trials are needed.

This case report describes a 13-year 10-month-old girl who underwent a deceased-donor split LT for primary diagnosis of biliary atresia at the age of 12 months, who presented with a lower GI bleed. Ultrasound and CT revealed a venous vascular anomaly involving the cecum and ascending colon, with communication of the SMV and pelvic veins consistent with a CEPS. Associated varices were noted in the pelvis along the uterus and urinary bladder. These findings were confirmed by trans-hepatic porto-venography, which was diagnostic and therapeutic as a successful embolization of the CEPS was performed using micro-coils. There were no complications following the procedure and no further GI bleeding occurred, illustrating the efficacy of this treatment option for CEPS. We discuss the literature regarding the presenting complaint of GI bleeding post-LT, CEPS as a rare cause of GI bleeding and its association with PV, and the classification and treatment of CEPS.

Background Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including bleeding (haemorrhage) from oesophageal and gastrointestinal varices. Variceal bleeding commonly occurs in children with chronic liver disease or portal vein obstruction. Prevention is therefore important. Primary prophylaxis of variceal bleeding in adults is the established standard of care because of the results of numerous randomised clinical trials demonstrating the efficacy of non-selective beta-blockers or endoscopic variceal ligation in decreasing the incidence of variceal bleeding. However, sclerotherapy is the only endoscopic prophylactic option currently available in infants weighing less than 10 kg of bodyweight due to the size of the endoscopic ligator. Objectives To assess the benefits and harms of sclerotherapy versus any type of beta-blocker for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis. Search methods We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, PubMed, Embase Elsevier, LILACS (Bireme), and Science Citation Index Expanded (Web of Science) in February 2019. We scrutinised the reference lists of the retrieved publications and performed a manual search from the main paediatric gastroenterology and hepatology conferences (NASPGHAN and ESPGHAN) abstract books from January 2008 to December 2018. We searched ClinicalTrials.gov, FDA, EMA, and WHO, for ongoing clinical trials. There were no language or document type restrictions. Selection criteria We planned to include randomised clinical trials irrespective of blinding, language, or publication status, assessing sclerotherapy versus any type of beta-blocker for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis. We planned to include quasi-randomised and other observational studies retrieved with the searches for randomised clinical trials for report of harm. Data collection and analysis We planned to collect and summarise data from randomised clinical trials as described in our protocol, using standard Cochrane methodologies. Main results We found no randomised clinical trials assessing sclerotherapy versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis. Authors' conclusions Randomised clinical trials assessing the benefits or harms of sclerotherapy versus beta-blockers for primary prophylaxis of oesophageal variceal bleeding in children and adolescents with chronic liver disease or portal vein thrombosis are lacking. Therefore, trials with adequate power and proper design, assessing the benefits and harms of sclerotherapy versus beta-blockers on patient-relevant clinical outcomes such as mortality, failure to control bleeding, and adverse events are needed. Unless such trials are conducted and the results become published, we cannot make any conclusions regarding the benefits or harms of the two interventions.

Background Current guidelines favour the use of bleeding stents over balloon tamponade (BT) for refractory variceal bleeding (VB) from oesophageal varices. However, data on the efficacy and safety of self‐expandable metal SX‐ELLA Danis stents (SEMS) are limited. Methods Cirrhotic patients receiving SEMS for VB at four tertiary care centres were included in this retrospective multicentre study. Rates of failure‐to‐control bleeding (within 5 days) and bleeding‐related mortality (6 weeks) were assessed. Results SEMS controlled VB in 79.4% (27/34) of patients. In the rest of patients, other rescue treatments including endoscopic band ligation (EBL, n = 3), SEMS renewed (n = 2) or Linton (n = 2) were applied; however, VB was only controlled in one patient. Early rebleeding within six weeks occurred in 17.6% (6/34) patients. Median SEMS dwell time was three (IQR:6) days. Overall n = 13/34 (38.2%) patients died with SEMS in situ. After SEMS removal, rebleeding and bleeding‐related death occurred in n = 7 (35%) and n = 5 (14.7%) patients respectively. Only 32.4% (10/34) patients did not experience any rebleeding within six weeks after SEMS removal. Bleeding‐related mortality was 47.1% (n = 16/34) and the median survival after SEMS placement was 2.1 months. Notably, no patient received an early transjugular intrahepatic portosystemic shunt (TIPS). The most common adverse events were stent dislocations (n = 13; 38.2%), while ulcers/necrosis of the oesophageal mucosa was seen in only four (11.8%) patients. Conclusion SEMS controlled refractory VB in most patients. However, bleeding‐related mortality remained high. While SEMS dislocations were frequent, ulcers/necrosis of the oesophagus was rare. Further studies should investigate whether the wider use of early TIPS reduces bleeding‐related mortality after SEMS placement.

Background Cirrhosis was previously perceived as a haemorrhagic disease state due to frequent associations with coagulopathy and bleeding. However, the coagulopathy of cirrhosis is complex with defects in both procoagulant and anticoagulant factors. Derangements in common laboratory indices of coagulation do not accurately reflect bleeding risk or protection from thrombotic events. Aims To assess the rate of pharmacological prophylaxis for venous thromboembolism (VTE) among hospital inpatients with cirrhosis and analyse factors associated with prophylaxis being inappropriately withheld. Methods A retrospective cohort study was performed in a tertiary teaching hospital. Patients included were admitted for greater than 48 h with discharge diagnosis codes corresponding to chronic liver disease and/or cirrhosis. The use of VTE chemoprophylaxis with enoxaparin was assessed in cirrhotic patients and non-cirrhotic controls. Patient data collected included contraindications to prophylaxis, known high-risk varices, international normalised ratio (INR), creatinine, bilirubin, haemoglobin and platelet count. Results Of 108 patients with cirrhosis eligible for VTE prophylaxis, 61 (56.5%) received prophylaxis compared to 104 (96.3%) non-cirrhotic patients. Platelets and INR were significantly different between those who did and did not receive VTE prophylaxis. On multivariate analysis, platelet count and INR were independent predictors for VTE not being administered. Conclusion The administration of chemoprophylaxis in accordance with the hospital guidelines was suboptimal in patients with cirrhosis. Platelet count and INR were independent predictors of prophylaxis use. Our results suggest persistent misperceptions that prolonged INR and thrombocytopenia predict bleeding risk in cirrhosis.

BACKGROUND AND AIM To investigate prognostic value of varices on computed tomography (CT) and redefine surrogate criteria for clinically significant portal hypertension (CSPH). METHODS We retrospectively enrolled 241 patients with compensated cirrhosis who underwent hepatic venous pressure gradient (HVPG) measurement from 2008 to 2013. Using CT and upper endoscopy findings obtained within 3 months from HVPG measurement, patients were classified into three groups: presence of standard surrogate for CSPH, defined as presence of varices on upper endoscopy and/or splenomegaly associated with thrombocytopenia (Group 1, n = 139); varices on CT without standard surrogate for CSPH (Group 2, n = 41); and free from both (Group 3, n = 61). HVPG value and overall survival (OS) rates were compared among three patient groups. Revised surrogate for CSPH was defined as presence of standard surrogate and/or presence of varices on CT (i.e. both Group 1 and Group 2). RESULTS Mean HVPG value in Group 2 was significantly higher than that in Group 3 (10.3 mmHg vs 6.5 mmHg, P

Background and aims The Baveno VI criteria enable non-invasive screening for esophageal varices. However, these criteria were established based on studies examining a large proportion of patients with viral hepatitis and relatively few patients with non-alcoholic fatty liver disease (NAFLD). Furthermore, because vibration-controlled transient elastography (VCTE) has a high incidence of measurement error, improved criteria are needed. We aimed to develop criteria based on magnetic resonance elastography (MRE) even among patients with NAFLD. Methods We performed a cross-sectional analysis of patients who had undergone MRE and/or VCTE as well as an esophagogastroduodenoscopy. The patients were classified as having either a low risk or a high risk of varices. The optimal cut-offs for ruling out esophageal varices were calculated for the MRE and VCTE liver stiffness measurement (LSM), the platelet count in an estimation cohort, and the cut-offs were then evaluated using validation cohorts composed of patients who had undergone only MRE or VCTE. Results The study included 627 patients (39% with NAFLD). The optimal cut-off values for the MRE-LSM and the platelet count were 4.2 kPa and 18.0 × 104 /μL, respectively. An MRE-LSM of 4.2 kPa plus a platelet count of 18.0 × 104 /μL had a negative predictive value of 1.00 for both low-risk plus high-risk varices as well as for high-risk varices in a validation cohort, enabling the presence of varices to be ruled out. Conclusions Magnetic resonance elastography might enable a safer avoidance of screening endoscopy, with a smaller measurement error, among patient populations with a high prevalence of NAFLD.

Introduction: Conclusive data on the accuracy and clinical applicability of non-invasive screening tests for oesophageal varices (OV) in patients with compensated cirrhosis remain lacking. We conducted this study to identify currently available tests, estimate their diagnostic performance and then exemplify how these could be utilized in clinical practice. Materials and methods: A systematic literature search was performed to identify all primary studies that reported accuracy using oesophagogastroduodenoscopy (OGD) as the gold standard. Sources searched included Ovid MEDLINE, Ovid EMBASE and The Cochrane Library databases. Results: Twenty-one studies with a total of 2471 patients were identified. Several tests were evaluated in more than three studies. Platelet count/spleen diameter ratio (PSR) had the highest summary area under the curve for detection of any size OV of 0.85 (95% confidence interval 0.78–0.92). At a cut-off of 909 (n = 4 studies) and prevalence rates of 10, 20, 30, 40 and 50% for OV, PSR screening correctly avoided the need for OGD in 70, 62, 55, 47 and 39% of patients, respectively. Conclusions: PSR appears to be the most accurate and validated non-invasive screening test for OV in patients with compensated cirrhosis. At a cut-off of 909, PSR could be clinically useful to avoid OGDs in a significant proportion of patients.

Background The need for a blood transfusion, defined as hemoglobin

Background and aim Acute upper gastrointestinal bleeding (UGIB) in cirrhosis is associated with significant morbidity and mortality and can be classified as acute variceal bleeding (AVB) or non-variceal bleeding (NVB). Differences in mortality, hospital length of stay (LOS), and 30-day readmission have yet to be determined. As such, the study aimed to evaluate differences in these clinical outcomes in cirrhotic patients admitted with UGIB. Methods This retrospective study included all cirrhotic patients hospitalized for UGIB who underwent upper endoscopy from July 2014 to July 2016. AVB was defined as the presence of varices on endoscopy with high-risk stigmata such as cherry-red spots. Mortality, intensive care unit admission, hospital LOS, and 30-day hospital readmission were recorded and compared among patients with AVB and NVB. Results A total of 116 patients with cirrhosis were included, 73 with AVB and 43 with NVB. Patients with NVB were older than those with AVB (60.4 ± 11.1 vs 55.0 ± 9.5, P = 0.006) whereas patients with AVB were more likely to have known esophageal varices (64.4% vs 37.2%, P = 0.007). Patients with AVB and NVB had similar mortality (15.1% vs 9.3%, P = 0.57), hospital LOS (4.9, interquartile range: 3.6-6.9 days vs 5.0, interquartile range: 2.7-8.3 days), and 30-day readmission rates (19.2% vs 30.2%, P = 0.18). Severity of clinical presentation was associated with increased LOS and overall mortality, including the need for intensive care unit admission, but these were not associated with 30-day readmission rates. Conclusion There were no differences in clinical outcomes, including mortality, in cirrhotic patients admitted with AVB and NVB.

Lumbar epidural varices are a rare cause of radicular pain mimicking lumbar disc herniation or other cyst-like masses including sequestrated disc herniation, facet joint synovial cyst, or perineural cyst. We report a case of a 36-year-old woman presenting with lumbar radicular pain caused by a lumbar epidural varix. Lumbar magnetic resonance imaging (MRI) revealed a cystic lesion in the ventral epidural space posterior to the right L4 body. Surgery was conducted and histopathology confirmed the diagnosis of an epidural varix. Lumbar epidural varices and other lumbar cystic lesions can commonly cause radicular pain. Physicians will benefit from increased awareness of epidural varices as a cause of lumbosacral radicular pain and the associated radiologic findings supporting differential diagnosis. In particular, careful interpretation of MRI scans may help ensure proper diagnosis of an epidural varix versus other cystic lesions. LEVEL OF EVIDENCE: V.

Background & aims Anticoagulants are commonly indicated in cirrhotic patients due to high rate of (pro)thrombotic conditions. Low molecular weight heparin (LMWH) is safe in patients with esophageal varices. However, the safety of LMWH is unknown in patients undergoing prophylactic endoscopic variceal ligation (EVL). To define the 4-week risk of bleeding and death after prophylactic EVL in cirrhotic patients continuously treated with LMWH. Methods All EVLs performed at a tertiary Italian Center from 2009 to 2016 were retrospectively reviewed. Patients treated with LMWH were classified as on-LMWH; the remaining as no-LMWH. Endoscopic characteristics at first and index EVL (that preceding an endoscopy either showing a bleeding episode or the absence of further treatable varices) and clinical events within 4 weeks from the procedures were recorded. Results and conclusions Five hundred fifty-three EVLs were performed in 265 patients (in 215 as a primary prophylaxis): 169 EVLs in 80 on-LMWH and 384 in 185 no-LMWH (4.9 ± 1.1 vs 4.8 ± 1.0 bands/session, respectively; P = .796). Six patients bled (2.2%) without between-groups difference (3.8% on-LMWH vs 1.6% no-LMWH, Log-rank P = .291). Large varices with red marks (100% vs 51.4%, P = .032), number of bands (5.6 ± 0.5 vs 4.6 ± 1.2, P = .004), underlying portal vein thrombosis (66.7% vs 23.6%, P = .033), and creatinine (2.2 ± 2.7 vs 1.0 ± 0.8 mg/dL, P = .001) at index EVL were significantly different between bleeders and non-bleeders. Six patients died within 4-week from index EVL, without between-groups difference (2.5% on-LMWH vs 2.2% no-LMWH, Log-rank P = .863). LMWH does not increase the risk of post-procedural bleeding and does not affect survival of cirrhotic patients undergoing prophylactic EVL.

Background and aim Minimal hepatic encephalopathy (MHE) predicts poor prognosis and could reflect an advanced liver disease. We aimed to assess whether MHE could be a surrogate marker of a further liver disease. Methods Prospective multicenter study including 320 cirrhotic patients, followed for up to 5 years, which were classified at baseline in compensated cirrhosis without (stage 1) and with varices (stage 2), one decompensating event (stage 3), and any second decompensating event (stage 4). Cirrhosis progression was defined by a transition towards a different stage (competing events: liver transplant due to hepatocellular carcinoma and non-liver-related death). MHE was detected by critical flicker frequency and psychometric tests. Results Minimal hepatic encephalopathy was diagnosed in 18.2% (57/314) of patients. Cirrhosis progression occurred in 38.1% (122/320) of patients, while liver transplant was required in 10.9% (35/320), and 19.1% (61/320) died. In competing risk regression, MHE was associated with disease progression: model 1 {subhazard ratio [sHR] 2.34 [95%confidence interval (CI) 1.58-3.46]; P = 0.0001}; model 2 [sHR 2.18 (95%CI 1.43-3.33); P = 0.0001]; model 3 [sHR 2.48 (95%CI 1.63-3.76); P = 0.0001]. The annual incidence rate of progression was higher in MHE patients: stage 1 (19.4 vs 5.6 cases per 100 person-years); stage 2 (26.8 vs 15.6); stage 3 (45.7 vs 16.5); and stage 4 (40.7 vs 12.8). MHE showed a higher cumulative incidence of disease progression from the first year in decompensated and the third year in compensated cirrhosis. Conclusion Minimal hepatic encephalopathy was associated with cirrhosis progression and showed a higher cumulative and annual incidence rate of disease progression. MHE could be a surrogate marker of disease progression, irrespective of cirrhosis status, identifying patients at risk of suffering a more aggressive cirrhosis form.

The outcome of compensated cirrhosis may vary considerably and cannot be predicted by routinely performed tests at present. The aim of this study was to evaluate possible predictors of clinical evolution in patients with Child-Pugh (C-P) class A cirrhosis because of untreatable causes by analysing clinical/biochemical/instrumental parameters evaluated at the time of diagnosis and during the subsequent long-lasting follow-up.Two hundred and seventy-two consecutive C-P class A cirrhotic patients (155 males; median age 63 years, range 34-81) were analysed. All patients were followed up for a median time of 96 months (range 21-144) through periodically performed clinical/biochemical/ultrasonographic and esophagogastroduodenoscopic examinations.During the follow-up, 97 individuals (36%) were clinically stable, 104 (38%) developed hepatocellular carcinoma (HCC) and 71 (26%) progressed towards C-P class B/C without developing cancer. One hundred and thirty-one patients (48%) died or underwent liver transplantation. Multivariate regression analysis showed that clinical stability was significantly associated with older age (P .001), the absence of diabetes (P = .04) and of oesophageal varices (P .001), serum albumin3.5 gr/dL (P = .01) and gamma globulin1.8 gr/dL (P = .01). HCC development was significantly associated with younger age (P = .01) and serum gamma globulin values ≥1.8 gr/dL (P .001). C-P score progression was associated with oesophageal varices (P .001), lower serum albumin (P = .03) and cholesterol (P = .01) values, and hypergammaglobulinemia (P = .02). Death was associated with younger age (P .001) and hypergammaglobulinemia (P = .01). Multivariate Cox regression analysis and Kaplan-Meier's survival test confirmed that gammaglobulinemia ≥1.8 g/dL was a significant predictor of death (P .02, and P .01 respectively).Hypergammaglobulinemia identifies C-P class A cirrhotic patients at higher risk of disease progression, HCC development and death.

We read with interest the research study by Dr Abe and colleagues and congratulate the authors on their excellent results with complete eradication of varices in 91 patients after endoscopic ultrasonography (EUS) and endoscopic injection sclerotherapy (EIS).1 Esophageal varices recurred in one third of patients but the addition of argon plasma coagulation (APC) consolidation treatment in a subgroup resulted in significantly lower variceal recurrence.

Aim Portosystemic shunts aggravate liver function by decreasing portal blood flow. The usefulness of balloon-occluded retrograde transvenous obliteration (B-RTO), a standardized therapeutic procedure for gastric fundal varices (GFV), for the improvement of liver function was evaluated in cirrhotic patients with or without varices. Methods The subjects were 161 patients with portosystemic shunts. A balloon catheter was inserted into the shunts, followed by the injection of 5% ethanolamine oleate through the catheter under balloon inflation. The balloon was kept inflated for 6 to 48 h. Results B-RTO was performed as a therapy for GFV in 112 patients and for the improvement of liver function in 49 patients. The targets were splenorenal shunts in 104 patients (93.6%) in the former group and 33 patients (67.3%) in the latter group, and the procedures were successfully completed in 109 (97.3%) and 39 (79.6%) patients, respectively. In both groups, the serum albumin levels were increased and the serum ammonia levels were decreased at more than 1 month after the procedures, compared with the baseline levels, whereas significant improvements in the Child-Pugh scores and prothrombin times were only seen in the latter group. In these patients, the portal blood flows evaluated using Doppler ultrasound were increased at 1 week after the procedures, compared with the baseline levels. Conclusions B-RTO is a useful therapeutic procedure for improving liver function even in patients without GFV by increasing the portal venous flow with successfully targeted, uncommon portosystemic shunts.

Background Laparoscopic spleen-preserving distal pancreatectomy for low-grade malignant pancreas tumours was recently demonstrated and can be performed with splenic vessel preservation (SVP) or splenic vessel resection (SVR). Whether one approach is superior to another is still a matter of debate. Methods A systematic literature search (PubMed, Embase, Science Citation Index, Springer-Link and Cochrane Central Register of Controlled Trials) was performed. Pooled intra- and post-operative outcomes were evaluated. Stratified and sensitivity analyses were performed to explore heterogeneity between studies and to assess the effects of the study qualities. Results A total of six studies were included. There was no significant difference for SVR and SVP in terms of overall post-operative complications and the pooled odds ratio (OR) was 0.87 (95% confidence interval (CI) 0.55-1.38, I2 = 25%). Meta-analysis on the pooled outcome of intraoperative operative time and blood loss favoured SVR; the mean differences were 18.64 min (95% CI 6.91-30.37 min, I2 = 21%) and 65.67 mL (95% CI 18.88-112.45 mL, I2 = 48%), respectively. Subgroup analysis showed a decrease incidences in perigastric varices (OR = 0.07, 95% CI 0.03-0.18, I2 = 29%) and splenic infarction (OR = 0.16, 95% CI 0.08-0.32, I2 = 0%) in SVP. Conclusion For selected patients who underwent laparoscopic spleen-preserving distal pancreatectomy, an increased preference for the SVP technique should be suggested considering its short-term benefits. However, in case of large tumours that distort and compress vessel course, SVR could be applied with acceptable splenic ischaemia and perigastric varices.

Endocervical varices are a rare cause of obstetrical hemorrhage. Usually presenting in the second and third trimesters, bleeding varices often require pregnancy termination or indicated preterm birth via cesarean delivery. Our patient experienced variceal hemorrhage at 12 weeks' gestation in a dichorionic twin pregnancy conceived through in vitro fertilization. A low-lying placenta resolved at 19 weeks followed by variceal regression at 22 weeks' gestation. Endocervical varices causing first-trimester hemorrhage may regress with resolution of a coexisting low placental implantation, permitting planned vaginal delivery, despite progressive hemodynamic changes of pregnancy. © 2017 Wiley Periodicals, Inc.

Background and aim Esophageal variceal bleeding is a life-threatening complication of liver cirrhosis. Upper gastrointestinal endoscopy was the gold standard for the diagnosis of esophageal varices (EVs). The study aimed to evaluate the accuracy of contrast-enhanced computed tomography (CT) in the diagnosis of EVs and moderate-severe EVs in patients with liver cirrhosis. Methods Medical records in cirrhotic patients who were admitted to our hospital between June 2012 and June 2014 were retrospectively reviewed. Two observers reviewed the contrast-enhanced CT scans to evaluate the presence and diameter of EVs. Area under curve (AUC), sensitivity, and specificity were calculated. Results A total of 52 cirrhotic patients were included in our study. According to the endoscopic results, 13.5% of these patients did not have any EVs, 11.5% had mild EVs, and 75% had moderate-severe EVs. The AUC of contrast-enhanced CT scans for the diagnosis of EVs was 0.835. The sensitivity and specificity were 95.56% and 71.43%, respectively. The AUC of contrast-enhanced CT scans for the diagnosis of moderate-severe EVs was 0.821. When the cut-off value for the diameter of EVs on contrast-enhanced CT scans was 3.9 mm, the sensitivity and specificity were 89.74% and 69.23%, respectively. Conclusions Contrast-enhanced CT scans had a moderate diagnostic accuracy for EVs in liver cirrhosis. It might be useful to decrease the use of upper gastrointestinal endoscopy in clinical practice.

Variceal haemorrhage is a major complication of portal hypertension that still causes high mortality in patients with cirrhosis. Improved knowledge of the pathophysiology of portal hypertension has recently led to a more comprehensive approach to prevent all the complications of this condition. Thus, optimal treatment of portal hypertension requires a strategy that takes into account the clinical stage of the disease and all the major variables that affect the risk of progression to the next stage and death. In patients with compensated liver disease, the correction of factors influencing the progression of fibrosis, in particular aetiologic factors, is now feasible in many cases and should be achieved to prevent the development or progression of gastroesophageal varices and hepatic decompensation. Once gastroesophageal varices have developed, non-selective beta-blockers remain the cornerstone of therapy. Carvedilol provides a greater decrease in portal pressure and is currently indicated as a first-choice therapy for primary prophylaxis. The treatment of acute variceal haemorrhage includes a combination of vasoactive drugs, antibiotics and endoscopic variceal band ligation. In high-risk patients, the early use of transjugular intrahepatic portosystemic shunt (TIPS) lowers the risk of re-bleeding and improves survival. Transjugular intrahepatic portosystemic shunt is the choice for uncontrolled variceal bleeding; a self-expandable metal stent or balloon tamponade can be used as a bridging measure. The combination of non-selective beta-blockers and endoscopic variceal band ligation reduces the risk of recurrent variceal bleeding and improves survival. In these cases, statins seem to further improve survival. Transjugular intrahepatic portosystemic shunt is indicated in patients who rebleed during secondary prophylaxis.

Portal hypertension is a clinical syndrome characterized by splenomegaly, with or without hypersplenism, and esphagogastric varices. Non‐cirrhotic portal hypertension (NCPH) belongs to the presinusoidal sub category of portal hypertension. We present the case of a young 35‐year‐old male who had presented with two episodes of upper gastrointestinal bleed. On endoscopy, he was found to have large esophageal varices. On general physical examination, there were diffuse hyperpigmented papules and nodules all over the body, with palmoplantar thickening. His liver function tests were normal. Computed tomography of the abdomen showed a dilated portal and splenic vein with splenomegaly and normal liver size and histopathology showed non‐cirrhotic portal fibrosis (NCPF). He had history of intake of oral indigenous medications for skin lesions. On investigating, patient was found to have chronic arsenicosis, which was likely the underlying etiology for NCPF as well. Hence, while evaluating patients of NCPF, it is imperative to rule out the use of indigenous medications, especially in the Indian scenario., We present a 37‐year‐old male who had upper gastrointestinal bleed and was found to have non cirrhotic portal hypertension. His examination revealed typical raindrop pigmentation of the palms and soles, which led us to the diagnosis of chronic arsenicosis as the cause of portal hypertension.

Pulmonary vein stenosis (PVS) is a rare disease that can cause haemoptysis. Acquired PVS is indicated as a complication associated with cardiac catheter intervention; however, the maze procedure has not been reported to induce PVS. Here, we describe the diagnosis and treatment strategy for the first case of PVS with haemoptysis due to the maze procedure. A 56-year-old man who underwent the maze procedure seven years previously was referred for repeated haemoptysis. Contrast-enhanced computed tomography (CT) revealed complete occlusion of the left superior pulmonary vein. Bronchoscopy revealed localized bronchial congestion and varices. He was diagnosed with PVS due to the maze procedure, and he underwent catheter-balloon angioplasty. After treatment, haemoptysis disappeared and bronchial congestion and varices improved. History of cardiac ablation (surgical or catheter intervention) and localized bronchial congestion findings might facilitate the accurate diagnosis of PVS with haemoptysis. Catheter-balloon angioplasty is a minimally invasive treatment for PVS.

PVT is the most frequent vascular complication after LT in small children, and a higher incidence has been observed in those transplanted for biliary atresia or with a LLSG. Thrombosis of the PV causes extrahepatic portal hypertension and is associated with splenomegaly and the development of venous neo-collaterals, including gastro-oesophageal varices and splenorenal shunts. It has also been incidentally suggested in the literature that patients who have had a Roux-en-Y loop for a biliary reconstruction may present with a cavernomatous transformation of the distal portion of the loop. In this study, 13 children with CEPH caused by thrombosis of the PV after LT were analysed. The study evidenced the development of two types of hepatopetal venous networks: (a) a large cavernoma along the Roux loop and around the biliary anastomosis, and (b) a network of neo-collaterals in the gastro-duodeno-pancreatic area that connected to the intrahepatic portal branches directly through the liver capsule. These hepatopetal venous networks between the venous system of the surrounding organs or the omentum and the intrahepatic portal branches can be identified by radiologists. The relevance for the transplanting physician and the transplant surgeon is discussed.

BACKGROUND: The presence of oesophageal varices is associated with the risk of upper gastrointestinal bleeding. Endoscopic variceal ligation is used to prevent this occurrence but the ligation procedure may be associated with complications. OBJECTIVES: To assess the beneficial and harmful effects of band ligation versus no intervention for primary prevention of upper gastrointestinal bleeding in adults with cirrhosis and oesophageal varices. SEARCH METHODS: We combined searches in the Cochrane Hepato‐Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, LILACS, and Science Citation Index with manual searches. The last search update was 9 February 2019. SELECTION CRITERIA: We included randomised clinical trials comparing band ligation verus no intervention regardless of publication status, blinding, or language in the analyses of benefits and harms, and observational studies in the assessment of harms. Included participants had cirrhosis and oesophageal varices with no previous history of variceal bleeding. DATA COLLECTION AND ANALYSIS: Three review authors extracted data independently. The primary outcome measures were all‐cause mortality, upper gastrointestinal bleeding, and serious adverse events. We undertook meta‐analyses and presented results using risk ratios (RRs) with 95% confidence intervals (CIs) and I(2) values as a marker of heterogeneity. In addition, we calculated the number needed to treat to benefit (NNTTB) for the primary outcomes . We assessed bias control using the Cochrane Hepato‐Biliary domains; determined the certainty of the evidence using GRADE; and conducted sensitivity analyses including Trial Sequential Analysis. MAIN RESULTS: Six randomised clinical trials involving 637 participants fulfilled our inclusion criteria. One of the trials included an additional small number of participants (< 10% of the total) with non‐cirrhotic portal hypertension/portal vein block. We classified one trial as at low risk of bias for the outcome, mortality and high risk of bias for the remaining outcomes; the five remaining trials were at high risk of bias for all outcomes. We downgraded the evidence to moderate certainty due to the bias risk. We gathered data on all primary outcomes from all trials. Seventy‐one of 320 participants allocated to band ligation compared to 129 of 317 participants allocated to no intervention died (RR 0.55, 95% CI 0.43 to 0.70; I(2) = 0%; NNTTB = 6 persons). In addition, band ligation was associated with reduced risks of upper gastrointestinal bleeding (RR 0.44, 95% CI 0.28 to 0.72; 6 trials, 637 participants; I(2) = 61%; NNTTB = 5 persons), serious adverse events (RR 0.55, 95% CI 0.43 to 0.70; 6 trials, 637 participants; I(2) = 44%; NNTTB = 4 persons), and variceal bleeding (RR 0.43, 95% CI 0.27 to 0.69; 6 trials, 637 participants; I² = 56%; NNTTB = 5 persons). The non‐serious adverse events reported in association with band ligation included oesophageal ulceration, dysphagia, odynophagia, retrosternal and throat pain, heartburn, and fever, and in the one trial involving participants with either small or large varices, the incidence of non‐serious side effects in the banding group was much higher in those with small varices, namely ulcers: small versus large varices 30.5% versus 8.7%; heartburn 39.2% versus 17.4%. No trials reported on health‐related quality of life. Two trials did not receive support from pharmaceutical companies; the remaining four trials did not provide information on this issue. AUTHORS' CONCLUSIONS: This review found moderate‐certainty evidence that, in patients with cirrhosis, band ligation of oesophageal varices reduces mortality, upper gastrointestinal bleeding, variceal bleeding, and serious adverse events compared to no intervention. It is unlikely that further trials of band ligation versus no intervention would be considered ethical.
