The role of endoscopy in the management of variceal hemorrhage

Impact of sarcopenia on variceal rebleeding in patients after endoscopic therapy: a multicenter retrospective cohort study based on propensity score matching

BACKGROUND

Sarcopenia is a common complication of liver cirrhosis and can be used for predicting dismal prognostic outcomes. This study aimed to evaluate the role of sarcopenia in rebleeding and mortality of liver cirrhosis patients after endoscopic therapy.

METHODS

The liver cirrhosis patients who received endoscopic treatment were enrolled. Propensity score matching (PSM) was used to overcome selection bias. Two-year rebleeding episodes and mortality after endoscopic therapy were recorded.

RESULTS

A total of 109 (32.4%) sarcopenia patients were reported. Before PSM, the frequency of rebleeding was significantly higher in the sarcopenia group relative to the non-sarcopenia group (41.3% vs. 15.9%, p < 0.001). Moreover, the multivariable analysis revealed that sarcopenia (p < 0.001, HR:2.596, 95% CI 1.591-4.237) was independently associated with a 2-year rebleeding episode. After PSM, the sarcopenia group exhibited an increased rebleeding rate as compared with non-sarcopenia group (44.4% vs. 15.3%, p < 0.001). According to multivariable analysis, sarcopenia (p < 0.001, HR:3.490, 95% CI 1.756-6.938) was identified as a significant predictor for 2-year rebleeding.

CONCLUSION

Sarcopenia was significantly associated with a high 2-year rebleeding rate in liver cirrhosis patients after endoscopic treatment. Therefore, the precise evaluation of a patient's nutritional status, including sarcopenia becomes mandatory before endoscopic treatment.

Proton Pump Inhibitors in Patients with Cirrhosis: Pharmacokinetics, Benefits and Drawbacks

PURPOSE OF REVIEW

This review explores the pharmacokinetics, benefits, and risks of proton pump inhibitors (PPIs) in cirrhotic patients, focusing on the appropriateness of their use and potential adverse effects.

RECENT FINDINGS

Recent studies highlight significant pharmacokinetic alterations in PPIs among cirrhotic patients, with marked increases in lansoprazole and pantoprazole exposure and relatively stable levels of esomeprazole. While effective for managing acid-related disorders and post-band ulcer rebleeding, evidence supporting PPI use for portal hypertension-related bleeding is lacking. Emerging research suggests potential adverse effects such as hepatic decompensation, spontaneous bacterial peritonitis, hepatic encephalopathy, and increased mortality, possibly linked to dysbiosis and bacterial translocation. PPI use in cirrhotic patients alters pharmacokinetics significantly, with esomeprazole potentially safer in advanced cirrhosis. The review advises caution in routine PPI use beyond acid-related conditions due to limited evidence and substantial risks. It underscores the need for careful risk-benefit assessments and exploration of alternative therapies. Future research should aim to identify safer management strategies for portal hypertension complications and to develop evidence-based guidelines for PPI use in patients with cirrhosis.

The diagnostic accuracy of triphasic abdominal CT in detecting esophageal varices

BACKGROUND

In Tanzania, triphasic abdominal Computed Tomography (CT) is a more accessible and non-invasive alternative for diagnosing esophageal varices, though its accuracy has not been thoroughly evaluated, therefore this study aimed to determine the diagnostic accuracy of triphasic abdominal CT in detecting esophageal varices using esophagogastroduodenoscopy (OGD) as the gold standard among patients with upper gastrointestinal bleeding at Muhimbili National Hospital (MNH).

METHODS

This cross-sectional study was conducted at MNH from January 2021 to May 2023. We sampled upper gastrointestinal bleeding patients who underwent both OGD and triphasic abdominal CT using non-probability consecutive sampling. The sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and accuracy of triphasic abdominal CT were assessed against OGD findings.

RESULTS

In a study of 200 participants, esophageal varices were detected in 54% by OGD and 53.5% by CT. We observed 105 true positives, 2 false positives, 90 true negatives, and 3 false negatives. Triphasic abdominal CT demonstrated a sensitivity of 97.2%, specificity of 97.8%, PPV of 98.1%, NPV of 96.8%, and an accuracy of 97.5%. Extraluminal findings included portal venous thrombosis in (22%), splenic collateral (51.5%), ascites (32%), hepatocellular carcinoma (13%), and periportal fibrosis (32%).

CONCLUSION

Triphasic abdominal Computed Tomography can be used as a reliable and non-invasive alternative modality for diagnosing and screening esophageal varices in resource-limited settings.

New sights in ectopic varices in portal hypertension

Ectopic varices and associated bleeding, although rare, pose a significant risk to patients with portal hypertension, carrying a relatively high mortality rate. These varices can occur in various anatomical regions, excluding the gastroesophageal region, which is typically associated with portal vein drainage. The limited data available in the literature, derived mostly from case reports and series, make the diagnosis and treatment of ectopic variceal bleeding particularly challenging. Furthermore, it is crucial to recognize that ectopic varices in different sites can exhibit variations in key decision-making factors such as aetiology and vascular anatomy, severity and bleeding risk and hepatic reserve. These factors significantly influence treatment strategies and underscore the importance of adopting individualized management approaches. Therefore, the objective of this review is to provide a comprehensive overview of the fundamental knowledge surrounding ectopic varices and to propose site-oriented, stepwise diagnosis and treatment algorithms for this complex clinical issue. A multidisciplinary treatment approach is strongly recommended in managing ectopic varices. In addition, to enhance clinical reference, we have included typical case reports of ectopic varices in various sites in our review, while being mindful of potential publication bias.

The Value of Follow-Up Liver Stiffness Changes Measured by Virtual Touch Quantification Elastography for Predicting Recurrence of Gastroesophageal Varices after Endoscopic Injection Sclerotherapy on Cirrhotic Patients

Background and Aims

Recurrence of gastroesophageal varices (GEVs) after sclerotherapy is a public health problem. However, mass screening of recurrence of GEVs through gastroscopy is a high-cost procedure. We aim to evaluate the changes in liver stiffness (LS) over time after endoscopic injection sclerotherapy (EIS) and determine its value in predicting the recurrence of GEVs.

Methods

One hundred and thirty-five patients with GEVs who underwent EIS treatment were included in this study. The patients were divided into two groups, namely, the nonrecurrence and recurrence groups, based on endoscopic findings at 6 months after discharge. LS measurements were obtained on five occasions. Repeated measure analysis of variance was employed to assess LS differences at different time points and compare them between the two groups.

Results

The LS values during the 6-month postdischarge period were consistently higher than the baseline value (measured on the day of hospitalization). The recurrence group demonstrated sustained elevated LS levels throughout the 6-month follow-up period, while the nonrecurrence group showed a gradual decline in LS. The difference in LS trend between the two groups was statistically significant (P = 0.04). The area under the curve (AUC) values for LS differences were 0.806, with a corresponding 95% confidence interval (CI) of 0.640-0.918 and a cut-off value of 0.556, indicating their potential utility in predicting GEV recurrence.

Conclusions

Longitudinal assessment of LS values in post-EIS patients can provide valuable information for predicting the recurrence of GEVs.

Esophageal Stent in Acute Refractory Variceal Bleeding: A Systematic Review and a Meta-Analysis

Background: Acute esophageal variceal bleeding accounts for up to 70% of upper-gastrointestinal bleeding in cirrhotic patients. About 10-20% of patients with acute variceal bleeding have refractory bleeding that is not controlled by medical or endoscopic therapy, and this condition can be life-threatening. Balloon tamponade is a long-standing therapy which is only effective temporarily and has several complications, while transjugular intrahepatic portosystemic shunt (TIPS) and liver transplantation may not be readily available at some centers. The use of self-expandable metal stents (SEMSs) in refractory esophageal variceal bleeding has been studied for effectiveness and adverse events and has been recommended for use as a bridge to a more definitive treatment. Aim: To investigate the effectiveness and safety of SEMSs in managing refractory variceal bleeding. Methods: A systematic search of the MEDLINE, EMBASE, and Cochrane library databases was performed from inception to October 2022 using the following terms: "esophageal stent", "self-expandable metal stents", "endoscopic hemostasis", "refractory esophageal varices", and "esophageal variceal bleeding". Studies were included in the meta-analysis if they met the following criteria: (1) patients' age older than 18 and (2) a study (or case series) that has at least 10 patients in the study. Exclusion criteria included (1) non-English publications, (2) in case of overlapping cohorts, data from the most recent and/or most appropriate comprehensive report were collected. DerSimonian-Laird random-effects meta-analysis was performed using the meta package in R statistical software(version 4.2.2). Results: Twelve studies involving 225 patients with 228 stents were included in the analyses. The mean age and/or median age ranged from 49.4 to 69 years, with a male-to-female ratio of 4.4 to 1. The median follow-up period was 42 days. The mean SEMS dwell time was 9.4 days. The most common cause of acute refractory variceal bleeding in chronic liver disease patients included alcohol use followed by viral hepatitis. The pooled rate of immediate bleeding control was 91% (95% CI 82-95%, I2 = 0). The pooled rate of rebleeding was 17% (95% CI 8-32%, I2 = 69). The pooled rate of stent ulceration was 7% (95% CI 3-13%, I2 = 0), and the pooled rate of stent migration was 18% (95% CI 9-32%, I2 = 38). The pooled rate of all-cause mortality was 38% (95% CI 30-47%, I2 = 34). Conclusions: SEMSs should be primarily considered as salvage therapy when endoscopic band ligation and sclerotherapy fail and can be used as a bridge to emergent TIPS or definitive therapy, such as liver transplantation.

Guidelines for the Management of Esophagogastric Variceal Bleeding in Cirrhotic Portal Hypertension

To standardize the diagnosis, treatment, and management of esophagogastric variceal bleeding (EVB) in patients with cirrhotic portal hypertension, the Chinese Society of Hepatology, the Chinese Society of Gastroenterology, and the Chinese Society of Digestive Endoscopy of the Chinese Medical Association brought together relevant experts, reviewed the latest national and international progress in clinical research on EVB in cirrhotic portal hypertension, and followed evidence-based medicine to update the Guidelines on the Management of EVB in Cirrhotic Portal Hypertension. The guidelines provide recommendations for the diagnosis, treatment, and management of EVB in cirrhotic portal hypertension and with the aim to improve the level of clinical treatment of EVB in patients with cirrhotic portal hypertension.

Evaluation of liver and splenic stiffness by acoustic radiation force impulse for assessment of esophageal varices

BACKGROUND

In routine clinical practice, assessment of portal hypertension (PHT) among patients with liver cirrhosis is done by a upper gastrointestinal endoscopy (UGIE); however, its invasive nature limits its use. Recent advances in ultrasound imaging make it possible to evaluate the tissue stiffness of the liver and spleen reflecting the severity of underlying fibrosis. Liver stiffness and spleen stiffness can be used to predict the presence of esophageal varices/PHT among cirrhotic patients.

AIM

To predict the presence or absence of esophageal varices by measuring the stiffness of the liver and spleen by ultrasonography (USG)-based acoustic radiation force impulse (ARFI).

METHODS

This cross-sectional study included 90 subjects with liver cirrhosis. Liver and splenic stiffness were measured along with the USG abdomen, UGIE and aspartate aminotransferase to platelet ratio index (APRI).

RESULTS

Liver and spleen stiffness were significantly higher in cirrhotic patients compared to chronic hepatitis B. The best cut-off value of liver stiffness (LS) obtained by the receiver operating characteristic (ROC) curve was 2.16 m/s for predicting esophageal varices (AUROC 0.78, p 0.0002). The best cut-off value of splenic stiffness (SS) obtained by the ROC curve was 3.04 m/s for predicting esophageal varices (AUROC 0.698, p 0.0274). When both LS and SS were taken together, the accuracy in predicting esophageal varices increased to 92.22%. An equation to predict "esophageal varices = (0.225 LS + 0.377SS) - 0.555" was derived.

CONCLUSION

LS and SS values of ≥ 2.16 m/s and 3.04 m/s, respectively, predict esophageal varices independently; however, combined assessment is better with 92% accuracy.

Comparison Between Pantoprazole Intermittent Dosing and Continuous Infusion in Suspected Upper Gastrointestinal Bleeding Prior to Endoscopy: Impact of a Pharmacist-Driven Protocol to Reduce Utilization of Pantoprazole Continuous Infusion

BACKGROUND

Current practice for patients with suspected or confirmed upper gastrointestinal bleeding (GIB) is to utilize a proton pump inhibitor (PPI) bolus followed by a continuous infusion for 72 hours. Literature has shown similar outcomes with intermittent bolus dosing compared to continuous infusion. Substitution would lead to reduced costs and utilization of resources.

METHODS

This was a retrospective case-control study conducted via chart review. Utilizing electronic healthcare record reports, patients in the control arm were screened for inclusion if they received a pantoprazole continuous infusion from December 1, 2020, to March 31, 2021. A total of 38 patients were included in the control arm. Patients in the experimental arm were screened for inclusion with pantoprazole intermittent therapy from January 1, 2022, to June 30, 2022. A total of 60 patients were included in the experimental arm. The primary outcome was a 30-day GIB recurrence. Secondary outcomes included 30-day hospital readmission, 30-day Clostridioides difficile (C. difficile), hospital length of stay (LOS), and number of pantoprazole vials utilized.

RESULTS

There was a 65% reduction in the 30-day GIB recurrence in the intermittent bolus arm compared to the continuous infusion arm. Thirty-day hospital readmission was 57% lower in the intermittent bolus arm compared to the continuous infusion arm. The LOS between the two arms was almost identical with the median being five days for the intermittent bolus arm and the median being four days for the continuous infusion arm. The 30-day C. difficile infection rate had 5% of patients acquiring C. difficile in the intermittent bolus arm and 2.5% in the continuous infusion arm. The intermittent bolus arm used 55% fewer pantoprazole vials than the continuous infusion arm.

CONCLUSION

In hospitalized patients, the utilization of pantoprazole intermittent bolus is not only comparably efficacious but potentially represents a safer and economically advantageous alternative compared to the current guideline recommendation of a 72-hour pantoprazole continuous infusion. Further studies could provide more robust data to support our findings and challenge the current recommendation for patients who meet the indication criteria.

Deep learning to predict esophageal variceal bleeding based on endoscopic images

OBJECTIVE

Esophageal varix (EV) bleeding is a particularly serious complications of cirrhosis. Prediction of EV bleeding requires extensive endoscopy experience; it remains unreliable and inefficient. This retrospective cohort study evaluated the feasibility of using deep learning (DL) to predict the 12-month risk of EV bleeding based on endoscopic images.

METHODS

Six DL models were trained to perform binary classification of endoscopic images of EV bleeding. The models were subsequently validated using an external test dataset, then compared with classifications performed by two endoscopists.

RESULTS

In the validation dataset, EfficientNet had the highest accuracy (0.910), followed by ConvMixer (0.898) and Xception (0.875). In the test dataset, EfficientNet maintained the highest accuracy (0.893), which was better than the endoscopists (0.800 and 0.763). Notably, one endoscopist displayed higher recall (0.905), compared with EfficientNet (0.870). When their predictions were assisted by artificial intelligence, the accuracies of the two endoscopists increased by 17.3% and 19.0%. Moreover, statistical agreement among the models was dependent on model architecture.

CONCLUSIONS

This study demonstrated the feasibility of using DL to predict the 12-month risk of EV bleeding based on endoscopic images. The findings suggest that artificial intelligence-aided diagnosis will be a useful addition to cirrhosis management.

Outcomes of Nonvariceal Upper Gastrointestinal Bleeding in Patients With Cirrhosis: A National Analysis

GOALS

We sought to evaluate hospital outcomes of cirrhosis patients with nonvariceal upper gastrointestinal bleeding (NVUGIB).

BACKGROUND

NVUGIB is common in patients with cirrhosis. However, national outcome studies of these patients are lacking.

STUDY

We utilized the 2014 Nationwide Readmission Database to evaluate NVUGIB in patients with cirrhosis, further stratified as no cirrhosis (NC), compensated cirrhosis (CC), or decompensated cirrhosis (DC). Validated International Classification of Diseases, Ninth Revision, Clinical Modification codes captured diagnoses and interventions. Outcomes included 30-day readmission rates, index admission mortality rates, health care utilization, and predictors of readmission and mortality using multivariable regression analysis.

RESULTS

Overall, 13,701 patients with cirrhosis were admitted with NVUGIB. The 30-day readmission rate was 20.8%. Patients with CC were more likely to undergo an esophagogastroduodenoscopy (EGD) within 1 calendar day of admission (74.1%) than patients with DC (67.9%) or NC (69.4%). Patients with DC had longer hospitalizations (4.1 d) and higher costs of care ($11,834). The index admission mortality rate was higher in patients with DC (6.2%) than in patients with CC (1.7%, P <0.001) or NC (1.4%, P <0.001). Predictors of 30-day readmission included performing an EGD >1 calendar day from admission (OR: 1.21; 95% CI, 1.00 to 1.46) and DC (OR: 1.78; 95% CI, 1.54 to 2.06). DC was a predictor of index admission mortality (OR: 3.68; 95% CI, 2.67 to 5.05).

CONCLUSIONS

NVUGIB among patients with DC is associated with higher readmission rates, mortality rates, and health care utilization compared with patients with CC and NC. Early EGD is a modifiable variable associated with reduced readmission rates. Early identification of high-risk patients and adherence to guidelines may improve clinical outcomes.

Transjugular intrahepatic portosystemic shunt with or without variceal embolization to prevent variceal rebleeding: an updated meta-analysis

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is an established treatment for portal hypertension complications. Still, the role of adjuvant variceal embolization is a matter of debate. Thus, we aim to evaluate the efficacy and safety of TIPS with variceal embolization versus TIPS alone to prevent variceal rebleeding.

RESEARCH DESIGN AND METHODS

We used PubMed, CENTRAL, and OVID to search for all randomized controlled trials (RCTs) and comparative observational studies up to 17 June 20221117 June 2022. We pooled binary outcomes using risk ratios (RRs) presented with 95% confidence intervals (CIs) using RevMan 5.4.

RESULTS

We included 11 studies (two RCTs and nine observational studies) with 1024 patients. Pooled RR favored TIPS with embolization in preventing variceal rebleeding (RR 0.58, 95% CI: 0.44, 0.76); however, there was no difference between the two groups regarding shunt dysfunction (RR 0.92, 95% CI: 0.68, 1.23), encephalopathy (RR 0.88, 95% CI: 0.70, 1.11), and death (RR 0.97, 95% CI: 0.77, 1.22).

CONCLUSIONS

TIPS with embolization can be an effective strategy for preventing variceal rebleeding; however, our results should be interpreted cautiously as most data were observational and the technical quality of the embolization is questionable. Further RCTs are required using the proper techniques of embolization and comparing TIPS with embolization with other treatment modalities such as endoscopic ligation, and balloon-occluded retrograde transvenous obliteration.

Timing of endoscopy in patients with cirrhosis and acute variceal bleeding: a single-center retrospective study

BACKGROUND

The optimal timing of endoscopy in liver cirrhosis with acute variceal bleeding (AVB) remains controversial in current guidelines and studies.

METHODS

Consecutive patients with liver cirrhosis and AVB were screened. The timing of endoscopy was calculated from the last presentation of AVB or the admission to endoscopy. Early endoscopy was defined as the interval < 12 h, < 24 h, or < 48 h. A 1:1 propensity score matching (PSM) analysis was performed. Five-day failure to control bleeding and in-hospital mortality were evaluated.

RESULTS

Overall, 534 patients were included. When the timing of endoscopy was calculated from the last presentation of AVB, PSM analysis demonstrated that the rate of 5-day failure to control bleeding was significantly higher in early endoscopy group defined as < 48 h (9.7% versus 2.4%, P = 0.009), but not < 12 h (8.7% versus 6.5%, P = 1.000) or < 24 h (13.4% versus 6.2%, P = 0.091), and that the in-hospital mortality was not significantly different between early and delayed endoscopy groups (< 12 h: 6.5% versus 4.3%, P = 1.000; <24 h: 4.1% versus 3.1%, P = 1.000; <48 h: 3.0% versus 2.4%, P = 1.000). When the timing of endoscopy was calculated from the admission, PSM analyses did not demonstrate any significant difference in the rate of 5-day failure to control bleeding (< 12 h: 4.8% versus 12.7%, P = 0.205; <24 h: 5.2% versus 7.7%, P = 0.355; <48 h: 4.5% versus 6.0%, P = 0.501) or in-hospital mortality (< 12 h: 4.8% versus 4.8%, P = 1.000; <24 h: 3.9% versus 2.6%, P = 0.750; <48 h: 2.0% versus 2.5%, P = 1.000) between early and delayed endoscopy groups.

CONCLUSION

Our study could not support any significant association of timing of endoscopy with cirrhotic patients with AVB.

Endoscopic Advances in Hepatology

Endoscopy is and remains an indispensable tool in diagnosing and managing liver disease and its complications. Due to the progress in advanced endoscopy, endoscopy has become an alternative route for many surgical, percutaneous, and angiographic interventions, not only as a backup tool when conventional interventions fail but increasingly as a first-line choice. The term endo-hepatology refers to the integration of advanced endoscopy in the practice of hepatology. Endoscopy is key in the diagnosis and management of esophageal and gastric varices, portal hypertensive gastropathy, and gastric antral vascular ectasia. Endoscopic ultrasound (EUS) can be used for the evaluation of the liver parenchyma, liver lesions, and surrounding tissues and vessels, including targeted biopsy and complemented with new software functions. Moreover, EUS can guide portal pressure gradient measurement, and assess and help manage complications of portal hypertension. It is crucial that each present-day hepatologist is aware of the (rapidly increasing) full spectrum of diagnostic and therapeutic tools that exist within this field. In this comprehensive review, we would like to discuss the current endo-hepatology spectrum, as well as future directions for endoscopy in hepatology.

Analysis of Complications and Risk Factors Other than Bleeding before and after Endoscopic Treatment of Esophagogastric Variceal Bleeding in Patients with Liver Cirrhosis

Objective. To identify any concomitant complications other than bleeding (COTB) before and after endoscopic treatment of esophagogastric variceal bleeding (EGVB) in liver cirrhosis patients and explore the underlying risk factors. Materials and Methods. Cirrhotic patients complicated with EGVB, who underwent interventional endoscopic treatments in our hospital from November 2017 to August 2020, were enrolled in this study. Clinical data were retrospectively analyzed for COTB at admission and within 2 years of the first endoscopic treatment. Patients were screened for potential risk factors of COTB before and after the treatment. Univariate analysis was performed to identify clinical factors of secondary complications, and statistically significant factors were included in the multivariate Cox and logistic regression analyses. Results. Of the 547 patients with cirrhosis, 361 individuals had COTB in the first endoscopic treatment. In this cohort, the top 3 prevalent incidences were portal vein thrombosis (PVT) or spongiosis, cholelithiasis, and pathogenic infections. The COTB did not occur at admission in 171 liver cirrhosis patients but happened at the follow-up. Higher Child-Pugh scores indicated potential risks of multiple concurrent complications, including bleeding. Risk factors for concomitant PVT or cavernous changes after endoscopic treatment of EGVB, pathogenic infections, and cholelithiasis could prolong the cirrhosis symptoms, while noncholestatic cirrhosis patients might have a lower risk than posthepatitis B cirrhosis patients, in the context of a higher degree of EGV and serum level of D-D and a lower blood calcium level. Conclusions. Clinical treatment and interventions can be tailored to avoid other complications during and after EGVB treatment, which can affect the outcome and prognosis of bleeding symptoms.

Diagnosis and Management of Esophagogastric Varices

Acute variceal bleeding (AVB) is a potentially fatal complication of clinically significant portal hypertension and is one of the most common causes of acute upper gastrointestinal bleeding. Thus, esophagogastric varices represent a major economic and population health issue. Patients with advanced chronic liver disease typically undergo an upper endoscopy to screen for esophagogastric varices. However, upper endoscopy is not recommended for patients with liver stiffness < 20 KPa and platelet count > 150 × 10⁹/L as there is a low probability of high-risk varices. Patients with high-risk varices should receive primary prophylaxis with either nonselective beta-blockers or endoscopic band ligation. In cases of AVB, patients should receive upper endoscopy within 12 h after resuscitation and hemodynamic stability, whereas endoscopy should be performed as soon as possible if patients are unstable. In cases of suspected variceal bleeding, starting vasoactive therapy as soon as possible in combination with endoscopic treatment is recommended. On the other hand, in cases of uncontrolled bleeding, balloon tamponade or self-expandable metal stents can be used as a bridge to more definitive therapy such as transjugular intrahepatic portosystemic shunt. This article aims to offer a comprehensive review of recommendations from international guidelines as well as recent updates on the management of esophagogastric varices.

Effects of postoperative use of proton pump inhibitors on gastrointestinal bleeding after endoscopic variceal treatment during hospitalization

BACKGROUND

Endoscopic variceal treatment (EVT) is recommended as the mainstay choice for the management of high-risk gastroesophageal varices and acute variceal bleeding in liver cirrhosis. Proton pump inhibitors (PPIs) are widely used for various gastric acid-related diseases. However, the effects of PPIs on the development of post-EVT complications, especially gastrointestinal bleeding (GIB), remain controversial.

AIM

To evaluate the effects of postoperative use of PPIs on post-EVT complications in patients with liver cirrhosis during hospitalization.

METHODS

Patients with a diagnosis of liver cirrhosis who were admitted to the Department of Gastroenterology of the General Hospital of Northern Theater Command, treated by an attending physician between January 2016 and June 2020 and underwent EVT during their hospitalization were included. Logistic regression analyses were performed to explore the effects of postoperative use of PPIs on the development of post-EVT complications during hospitalization. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.

RESULTS

A total of 143 patients were included. The incidence of post-EVT GIB and other post-EVT complications was 4.90% and 46.85%, respectively. In the overall analyses, postoperative use of PPIs did not significantly reduce the risk of post-EVT GIB (OR = 0.525, 95%CI = 0.113-2.438, P = 0.411) or other post-EVT complications (OR = 0.804, 95%CI = 0.413-1.565, P = 0.522). In the subgroup analyses according to the enrollment period, type and route of PPIs after the index EVT, use of PPIs before the index EVT, use of vasoactive drugs after the index EVT, indication of EVT (prophylactic and therapeutic), and presence of portal venous system thrombosis, ascites, and hepatocellular carcinoma, the effects of postoperative use of PPIs on the risk of post-EVT GIB or other post-EVT complications remain not statistically significant.

CONCLUSION

Routine use of PPIs after EVT should not be recommended in patients with liver cirrhosis for the prevention of post-EVT complications during hospitalization.

The effect of prophylactic antibiotics in acute upper gastrointestinal bleeding patients in the emergency department

BACKGROUND

Currently, prophylactic antibiotics are recommended only for cirrhotic patients with acute upper gastrointestinal bleeding (AUGIB); however, the benefit for other AUGIB patients remains undetermined. We aimed to compare the clinical outcomes between patients with AUGIB with and without prophylactic antibiotics to identify the population that requires this therapy.

METHODS

Patients with AUGIB admitted between 1st January 2019 and 31st December 2021 in the Emergency Department of Peking Union Medical College Hospital were enrolled. Patients were divided into the antibiotic and non-antibiotic groups. The primary outcome was in-hospital mortality, and the secondary outcome was the onset of new infection. The risk factors for mortality and infection were analyzed, and stratification analysis of prophylactic antibiotics was performed. Continuous data were analyzed using the t-test or nonparametric rank sum test, and categorical data were analyzed using the Chi-square test or Fisher's exact test. Indicators with significant differences between the groups were included for logistic regression analysis. A P-value <0.05 was considered statistically significant.

RESULTS

A total of 392 individuals were included, among them, 281 patients received prophylactic antibiotics, and 111 patients did not receive prophylactic antibiotics. The mortality rates were significantly lower in the antibiotic group than in the non-antibiotics group (6.41% vs. 17.12%, P=0.001). The risk factors for infection were varicose veins (P=0.045) and endotracheal intubation (P=0.005) in the prophylactic antibiotic group, and endoscopic treatment (P=0.010) in the non-prophylactic antibiotic group. Stratified analyses showed that patients with age ≥ 65 years, endotracheal intubation, endoscopic treatment, and AUGIB of variceal etiologies benefited from prophylactic antibiotics.

CONCLUSION

AUGIB patients may benefit from prophylactic antibiotics to decrease mortality, especially those aged ≥ 65 years and those with endotracheal intubation, endoscopic treatment, and variceal etiologies.

Balloon-Occluded Esophageal Variceal Obliteration Procedure: A Novel Technique Report from Three Centers

Introduction: Esophageal variceal bleeding (EVB) is a potentially fatal complication of cirrhosis. The purpose of the present study was to evaluate the safety and efficacy of a novel technique of balloon-occluded esophageal varices (EVs) obliteration (BEVO) for EVs classified as F2 (medium size, F2-EVs) and F3 (large size, F3-EVs). Materials and Methods: Between December 2020 and December 2021, a total of 73 consecutive patients with EVs were treated using BEVO. An injection of sclerosant was administered via direct puncture of the varices during balloon occlusion. Immediate postprocedural Doppler endoscopic ultrasonography (EUS) was conducted to evaluate the blood flow in the EVs. Several factors, including the technical success, controlling of acute bleeding, intraoperative bleeding at the injection site, variceal eradication, variceal recurrence, and BEVO-related complications, were assessed. Results: BEVO was successfully performed in all patients. Immediate hemostasis was achieved in 100% (25/25) of patients with active EVB. The incidence of injection site intraoperative bleeding presenting as oozing and spurting bleeding was 76.71% (56/73) and 8.22% (6/73), respectively. Based on Doppler EUS and endoscopic examination, EVs were completely eradicated in 71 out of 73 patients (97.26%) after three sessions. A total of 3 (4.11%) patients were diagnosed with EV recurrence during follow-up after complete EV eradication. Retrosternal chest discomfort (13.70%; 10/73) and abdominal bloating (2.74%; 2/73) were spontaneously relieved after a few days. No serious BEVO-related complications were observed. Discussion: BEVO is a convenient and effective treatment for obliterating F2 and F3 EVs. Clinical Trial Registration No. ChiCTR2000039974.

Update on the management of upper gastrointestinal bleeding

Upper gastrointestinal bleeding is a common emergency presentation requiring prompt resuscitation and management. Peptic ulcers are the most common cause of the condition. Thorough initial management with a structured approach is vital with appropriate intravenous fluid resuscitation and use of a restrictive transfusion threshold of 7-8 g/dL. Pre-endoscopic scoring tools enable identification of patients at high risk and at very low risk who might benefit from specific management. Endoscopy should be carried out within 24 h of presentation for patients admitted to hospital, although optimal timing for patients at a higher risk within this period is less clear. Endoscopic treatment of high risk lesions and use of subsequent high dose proton pump inhibitors is a cornerstone of non-variceal bleeding management. Variceal haemorrhage results in higher mortality than non-variceal haemorrhage and, if suspected, antibiotics and vasopressors should be administered urgently, before endoscopy. Oesophageal variceal bleeding requires endoscopic band ligation, whereas bleeding from gastric varices requires thrombin or tissue glue injection. Recurrent bleeding is managed by repeat endoscopic treatment. If uncontrolled bleeding occurs, interventional radiological embolisation or surgery is required for non-variceal bleeding or transjugular intrahepatic portosystemic shunt placement for variceal bleeding.

Mastering Core Recommendations during HEPAtology ROUNDS in Patients with Advanced Chronic Liver Disease

Efficient and thorough care of hospitalized patients with advanced chronic liver disease is of utter importance to improve outcomes and optimize quality of life. This requires understanding current evidence and best practices. To facilitate focus on up-to-date knowledge and a practical approach, we have created the HEPA-ROUNDS mnemonic while outlining a practical review of the literature with critical appraisal for the busy clinician. The HEPA-ROUNDS mnemonic provides a structured approach that incorporates critical concepts in terms of prevention, management, and prognostication of the most common complications frequently encountered in patients with advanced chronic liver disease. In addition, implementing the HEPA-ROUNDS mnemonic can facilitate education for trainees and staff caring for patients with advanced chronic liver disease.

Association of endoscopic variceal treatment with portal venous system thrombosis in liver cirrhosis: a case-control study

BACKGROUND

The association of endoscopic variceal treatment (EVT) with portal venous system thrombosis (PVST) in liver cirrhosis is still unclear.

METHODS

PVST was assessed by contrast-enhanced CT or MRI in 406 cirrhotic patients from our prospective database. Case and control groups, which are defined as patients with and without PVST, respectively, were matched at a ratio of 1:1 according to age, gender, Child-Pugh class, and MELD score. History of EVT was reviewed. Logistic regression analysis was used to identify the risk factors for PVST. Odds ratios (ORs) were calculated. Subgroup analyses were further performed in terms of degree and location of PVST.

RESULTS

Overall, 109 patients each were included in case and control groups. The case group had a significantly higher proportion of patients who had undergone EVT than the control group (53.2% versus 18.3%; p < 0.001). In detail, the case group had significantly higher proportions of patients who had undergone EVT for controlling bleeding (45.9% versus 14.7%; p < 0.001), endoscopic variceal ligation (EVL) alone (19.3% versus 9.2%; p = 0.033), and EVL combined with endoscopic cyanoacrylate glue injection (24.8% versus 5.5%; p < 0.001). EVT was independently associated with PVST (OR = 4.258; p < 0.001). In subgroup analyses, EVT remained independently associated with partial PVST (OR = 10.063; p < 0.001), complete PVST/fibrotic cord (OR = 4.889; p = 0.008), thrombosis within main portal vein (OR = 5.985; p < 0.001), and thrombosis within superior mesenteric and splenic veins (OR = 5.747; p < 0.001).

CONCLUSIONS

EVT may lead to a higher risk of PVST, especially more severe PVST, in liver cirrhosis. Screening for and prophylaxis of PVST after EVT should be further explored.

Variceal Bleeding: Beyond Banding

Despite advances in the management of complications of portal hypertension, variceal bleeding continues to be associated with significant morbidity and mortality. While endoscopic variceal band ligation remains first line therapy for treating bleeding and high-risk non-bleeding esophageal varices, alternate therapies have been explored, particularly in cases of refractory bleeding. The therapies being explored include stent placement, hemostatic powder use, over-the-scope clips and others. For gastric variceal bleeding, endoscopic ultrasound-guided therapies have recently emerged as promising interventions for hemostasis. The aim of this article is to highlight these alternative therapies and their potential role in the management of gastric and esophageal variceal bleeding.

Prophylactic cyanoacrylate injection for gastric extension of esophageal varices: a randomized controlled trial

Aim of the study

Gastric variceal bleeding is more severe and fatal than esophageal bleeding. Injection of cyanoacrylate into bleeding gastric varices is recommended, but prophylactic injection is debatable. Aim of this study is to evaluate prophylactic cyanoacrylate injection into gastric extension of esophageal varices type 2 (GOV2).

Material and methods

This randomized controlled trial included 75 patients (3 groups) with risky or bleeding esophageal varices and non-bleeding GOV2. Group A received a cyanoacrylate GOV2 injection, esophageal variceal band ligation (EBL), and β-blocker (BB); group B received EBL and BB; and group C received EBL. Follow-up for ≥ 24 weeks to check for bleeding or death was performed.

Results

Baseline variables were comparable among the 3 groups. During follow-up (median, 37.5 weeks), increasing gastric extension and or bleeding risk signs were significantly lower in group A (0%) than B (12%) and C (32%) (p < 0.001). Bleeding occurred more in groups B (24%) and C (24%) than in A (8%) (p = 0.2). Gastric extension size was an independent predictor of bleeding (p = 0.03). Portal hypertensive gastropathy (PHG) decreased in groups A (24%) and B (24%) more than in C (8%) (p = 0.5). Mortality rates were 0.0% in group A, 8% in B, and 4% in C (p = 0.2).

Conclusions

Prophylactic cyanoacrylate injection into GOV2 before EBL significantly decreased the varix size and risk signs for bleeding with a statistically insignificant tendency to decrease the bleeding rate. A large gastric extension was an independent predictor of bleeding. Adding β-blockers can potentially decrease PHG and bleeding risk. An independent study with a larger sample size is recommended to confirm the rate of bleeding and test the mortality difference.

Validation of the EVendo score for the prediction of varices in cirrhotic patients

BACKGROUND

Screening endoscopy for varices may be deferred when the calculated EVendo score is ≤3.90. This novel score has not been validated in an external cohort. This study aimed to assess the performance of the EVendo score and compare it with the Baveno VI criteria.

METHODS

We identified and calculated this score in all cirrhotic patients who underwent screening endoscopy for the first time with laboratory tests and liver stiffness measurements within 6 months of the endoscopy date.

RESULTS

In total, 103 patients were included. An EVendo score of ≤3.90 identified patients with no gastroesophageal varices (GEV) and varices needing treatment (VNT) with sensitivities of 82% and 83% and specificities of 57% and 34%, respectively. The negative predictive value for VNT was 94%. A comparison with the Baveno VI criteria in Child-Turcotte-Pugh-A patients showed spared endoscopy and missed VNT rates with EVendo score cutoffs of ≤3.9 and ≤4.5 and the Baveno VI criteria of 25%, 33%, and 16.6% and 1.7%, 1.7%, and 0%, respectively.

CONCLUSIONS

EVendo score is reliable in clinical practice for predicting GEV and VNT. The number of spared endoscopies was higher than that with the Baveno VI criteria; however, there were more missed VNT cases.

Endoscopic Treatment of Esophageal Varices

Acute variceal bleeding is a complication of portal hypertension, usually due to cirrhosis, with high morbidity and mortality. There are 3 scenarios for endoscopic treatment of esophageal varices: prevention of first variceal bleed, treatment of active variceal bleed, and prevention of rebleeding. Patients with cirrhosis should be screened for esophageal varices. Recommended endoscopic therapy for acute variceal bleeding is endoscopic variceal banding. Although banding is the first-choice treatment, sclerotherapy may have a role. Treatment with Sengstaken-Blakemore tube or self-expanding covered metallic esophageal stent can be used for acute variceal bleeding refractory to standard pharmacologic and endoscopic therapy.

Safety and Feasibility of Early Oral Nutrition after Endoscopic Treatment for Patients with Liver Cirrhosis: A Historical-prospective, Comparative-Effectiveness Study

BACKGROUND

This study aimed to evaluate the safety and efficacy of early oral nutrition (EON) after endoscopic treatment compared with parenteral nutrition (PN) for patients with gastroesophageal variceal bleeding varices as cirrhotic complications.

METHODS

This historical-prospective study enrolled patients from Qilu Hospital of Shandong University in China with gastroesophageal varices as cirrhotic complications and undergoing endoscopic therapy. A total of 197 patients who fasted for 4 h after treatment were prospectively enrolled as the oral nutrition group whereas those who fasted for more than 48 h were retrospectively matched in a ratio of 1:1 as the parenteral nutrition group. The primary endpoint was variceal re-bleeding, whereas the secondary endpoints were mortality and adverse events during the 42-day follow-up. Hospitalisation duration and expenses, levels of inflammatory factors, defecation time, and the satisfaction of patients were evaluated.

RESULTS

During the 42-day follow-up, no significant difference was observed in the rate of variceal re-bleeding (P = 0.586) and morality (P = 1.000) between the oral nutrition group and the parenteral nutrition group. However, the average days of hospitalisation (P < 0.001) and expenses (P < 0.001) were significantly decreased in the oral nutrition group. Furthermore, C-reactive protein lever (P = 0.002) and defecation time (P < 0.001) were lower, whereas the satisfaction rate was higher (P < 0.001) in the oral nutrition group than those in the parenteral nutrition group. Linear regression analysis showed that tissue adhesive dosage was related to diet time (P = 0.038, 95% CI: 0,135-4.516).

CONCLUSIONS

EON was proven to be safe, feasible, and hence, recommended after endoscopic treatment in patients with cirrhosis. This article is protected by copyright. All rights reserved.

Risk Factors for Esophageal Collateral Veins in Cirrhosis with and without Previous Endoscopic Esophageal Variceal Therapy

BACKGROUND

Portosystemic collateral vessels are a sign of portal hypertension in liver cirrhosis. Esophageal collateral veins (ECVs) are one major type of portosystemic collateral vessels, which increase the recurrence of esophageal varices and bleeding after variceal eradication. However, the risk factors for ECVs were still unclear.

METHODS

We retrospectively screened cirrhotic patients who had contrast-enhanced computed tomography (CT) images to evaluate ECVs and upper gastrointestinal endoscopic reports to evaluate gastroesophageal varices at our department. Univariate and multivariate logistic regression analyses were performed to explore the independent risk factors for ECVs. Odds ratios (ORs) were calculated. Subgroup analyses were performed in patients with and without previous endoscopic variceal therapy which primarily included endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS).

RESULTS

Overall, 243 patients were included, in whom the prevalence of ECVs was 53.9%. The independent risk factors for ECVs were hepatitis C virus infection (OR = 0.250, p = 0.026), previous EVL (OR = 1.929, p = 0.044), platelet (OR = 0.993, p = 0.008), and esophageal varices needing treatment (EVNTs) (OR = 2.422, p = 0.006). The prevalence of ECVs was 60.8% (73/120) in patients undergoing EVL, 50% (10/20) in those undergoing EIS, and 47.5% (48/101) in those without previous endoscopic variceal therapy. The independent risk factors for ECVs were the use of nonselective beta-blockers (OR = 0.294, p = 0.042) and EVNTs (OR = 3.714, p = 0.006) in subgroup analyses of patients with and without previous endoscopic variceal therapy, respectively.

CONCLUSIONS

The presence of ECVs should be closely associated with the severity of portal hypertension in liver cirrhosis. Risk of ECVs might be increased by previous EVL.

Comparative study for predictability of type 1 gastric variceal rebleeding after endoscopic variceal ligation: High-frequency intraluminal ultrasound study

BACKGROUND

The efficacy of endoscopic ultrasonography for the follow-up of gastric varices treated with endoscopic variceal ligation (EVL) has not been established.

AIM

To evaluate the diagnostic correlation of esophagogastroduodenoscopy (EGD) and high-frequency intraluminal ultrasound (HFIUS) for type 1 gastric varices (GOV1) after EVL and to identify the predictability for rebleeding of EGD and HFIUS.

METHODS

In liver cirrhosis patients with GOV1, we performed endoscopic follow-up using EGD and HFIUS synchronously after EVL for hemorrhage from GOV1. Endoscopic grading and red color signs were analyzed using EGD, and the largest variceal cross-sectional areas were measured using HFIUS. In addition, 1-year follow-up was performed. Variceal rebleeding was defined as the presence of hematemesis, hematochezia, or melena without other evidence of bleeding on endoscopic follow-up.

RESULTS

In 26 patients with GOV1, variceal cross-sectional areas on HFIUS of GOV1 was poorly correlated with EGD grading of GOV1 (r = 0.36). In 17 patients who completed the 1-year follow-up, variceal cross-sectional areas on HFIUS was a good predictor of subsequent rebleeding, whereas EGD grading was not a predictor of subsequent rebleeding.

CONCLUSION

HFIUS measurement is more predictive of GOV1 rebleeding than EGD grading, so HFIUS measurement may be necessary for endoscopic follow-up after EVL in patients with GOV1.

Outcomes of early versus delayed endoscopy in cirrhotic patients with acute variceal bleeding: a systematic review with meta-analysis

OBJECTIVES

Endoscopy is the mainstay treatment option for acute variceal bleeding (AVB) in liver cirrhosis. However, the optimal timing of endoscopy in such patients remains unclear.

METHODS

PubMed, EMBASE and Cochrane Library databases were searched. We compared the mortality, incidence of rebleeding, length of stay, endoscopic hemostasis, need for salvage and units of transfusion between cirrhotic patients with AVB who underwent early and delayed endoscopy. Meta-analyses were performed by using a random-effect model. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Subgroup analysis was performed in studies where early endoscopy was defined as <12 h.

RESULTS

Nine retrospective studies involving 2824 patients were included. The early endoscopy group had a significantly lower overall mortality than the delayed endoscopy group in overall analysis (OR = 0.56, 95% CI, 0.33-0.95, P = 0.03), but the difference between them was NS in subgroup analysis (OR = 0.72, 95% CI, 0.38-1.38, P = 0.33). In-hospital (OR = 0.77, 95% CI, 0.26-2.32, P = 0.65) and 6-week (OR = 0.78, 95% CI, 0.42-1.47, P = 0.45) mortality were not significantly different between them. Overall rebleeding was not significantly different between early and delayed endoscopy groups in both overall (OR = 0.88, 95% CI, 0.51-1.51, P = 0.63) and subgroup (OR = 1.04, 95% CI, 0.55-1.95, P = 0.90) analyses. In-hospital (OR = 1.41, 95% CI, 0.67-2.96, P = 0.37) and 6-week (OR = 0.93, 95% CI, 0.40-2.17, P = 0.86) rebleeding remained not significantly different between them. Additionally, the length of stay, endoscopic hemostasis, need for salvage and units of transfusion were not significantly different between them.

CONCLUSIONS

Early endoscopy may improve the survival of cirrhotic patients with AVB, but has no remarkable benefit on the prevention of rebleeding. These findings should be further validated by high-quality studies.

Baveno criteria perform better than expanded Baveno and Rete Sicilia Selezione Terapia-Hepatitis C virus criteria for predicting varices needing treatment

BACKGROUND AND AIMS

Endoscopy is the gold standard for the detection and staging of varices. Baveno, expanded Baveno, and Rete Sicilia Selezione Terapia-hepatitis C virus (RESIST-HCV) criteria predict varices non-invasively in patients with cirrhosis. We assessed the performance of these criteria for predicting varices needing treatment (VNT).

METHODS

Consecutive patients with compensated cirrhosis due to viral etiologies evaluated between January 2014 and May 2017 were included in this retrospective analysis of a prospectively maintained database. VNTs were defined as either large varies or small varices with red color signs on endoscopy. Performance characteristics to predict VNTs were estimated for the three criteria and spared endoscopy rate (SER) and missed VNT rates were determined.

RESULTS

Two hundred and ninety-five treatment-naïve cirrhosis patients, etiology hepatitis B (n = 154) or hepatitis C (n = 141), mean age 43.1 ± 13.2 years, 127 (43.1%) males were included. The median liver stiffness measurement (LSM) and platelet counts were 19.7 (interquartile range [IQR]: 14.8-28.8) kPa and 119 (IQR: 80-160) × 103/mm3, respectively. The SER and missed VNT rates were as follows-for Baveno criteria: 18.3% and 6.2%; expanded Baveno: 35.3% and 29.2%; and for RESIST-HCV criteria: 37.3% and 22.9%. The sensitivity, specificity, positive predictive value, and negative predictive value were 93.7%, 21.9%, 18.9%, and 94.7% for Baveno criteria; 70.8%, 42.3%, 19.3%, and 88.1% for expanded Baveno; and 77.1%, 44.5%, 21.3%, and 90.9% for RESIST-HCV criteria, respectively.

CONCLUSION

Baveno criteria are useful to avoid screening endoscopies in patients with cirrhosis of viral etiologies. In contrast, although expanded Baveno criteria and RESIST-HCV criteria spare more endoscopies, a high missed VNT rate limits their applicability.

Prognostic factors associated with upper gastrointestinal bleeding based on the French multicenter SANGHRIA trial

Background and study aims  Prognostic and risk factors for upper gastrointestinal bleeding (UGIB) might have changed overtime because of the increased use of direct oral anticoagulants and improved gastroenterological care. This study was undertaken to assess the outcomes of UGIB in light of these new determinants by establishing a new national, multicenter cohort 10 years after the first. Methods  Consecutive outpatients and inpatients with UGIB symptoms consulting at 46 French general hospitals were prospectively included between November 2017 and October 2018. They were followed for at least for 6 weeks to assess 6-week rebleeding and mortality rates and factors associated with each event. Results  Among the 2498 enrolled patients (mean age 68.5 [16.3] years, 67.1 % men), 74.5 % were outpatients and 21 % had cirrhosis. Median Charlson score was 2 (IQR 1-4) and Rockall score was 5 (IQR 3-6). Within 24 hours, 83.4 % of the patients underwent endoscopy. The main causes of bleeding were peptic ulcers (44.9 %) and portal hypertension (18.9 %). The early in-hospital rebleeding rate was 10.5 %. The 6-week mortality rate was 12.5 %. Predictors significantly associated with 6-week mortality were initial transfusion (OR 1.54; 95 %CI 1.04-2.28), Charlson score > 4 (OR 1.80; 95 %CI 1.31-2.48), Rockall score > 5 (OR 1.98; 95 %CI 1.39-2.80), being an inpatient (OR 2.45; 95 %CI 1.76-3.41) and rebleeding (OR 2.6; 95 %CI 1.85-3.64). Anticoagulant therapy was not associated with dreaded outcomes. Conclusions  The 6-week mortality rate remained high after UGIB, especially for inpatients. Predictors of mortality underlined the weight of comorbidities on outcomes.

Cap-Assisted Endoscopic Sclerotherapy vs Ligation in the Long-Term Management of Medium Esophageal Varices: A Randomized Trial

Compared with endoscopic variceal ligation (EVL), cap-assisted endoscopic sclerotherapy (CAES) improves efficacy in the treatment of small esophageal varices (EVs) but has not been evaluated in the management of medium EVs. The aim of this study was to compare CAES with EVL in the long-term management of patients exhibiting cirrhosis with medium EVs and a history of esophageal variceal bleeding (EVB), with respect to variceal eradication and recurrence, adverse events, rebleeding, and survival.

Endoscopic Ultrasound-Guided Coil Embolization With Absorbable Gelatin Sponge Appears Superior to Traditional Cyanoacrylate Injection for the Treatment of Gastric Varices

Gastric variceal (GV) bleeding is a feared complication of cirrhosis. Traditional endoscopic treatment with cyanoacrylate (CYA) injection can be challenging. Alternatively, endoscopic ultrasound (EUS)-guided delivery of hemostatic coils has shown high therapeutic success without the complications profile of CYA alone. Our aim was to compare the clinical outcomes of EUS-guided coil embolization with endoscopic CYA injection for the treatment of GV.

Transjugular intrahepatic portosystemic shunt in patients treated with a balloon tamponade for variceal hemorrhage without response to high doses of vasoactive drugs: A real-world multicenter retrospective study

OBJECTIVE

To evaluate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) and non-TIPS therapy (endoscopy and/or nonselective beta-blockers [NSBB]) in patients with cirrhosis and active variceal hemorrhage who did not respond to high-dose vasoactive drugs and required balloon tamponade for hemostasis.

METHODS

Medical records of cirrhotic patients who did not respond to high-dose vasoactive drugs and required balloon tamponade for hemostasis at five university hospitals in China between January 2011 and December 2018 were reviewed. Treatment outcomes were compared between the TIPS and the non-TIPS groups.

RESULTS

Treatment failure of variceal hemorrhage within 5 days was reported in six patients of the non-TIPS group (N = 70) and none of the TIPS group (N = 66) (P = .028). The TIPS group had a higher 1-year variceal rebleeding-free rate compared with the non-TIPS group (95.5% vs 60.0%, P < .001). One patient treated with TIPS and nine with non-TIPS therapy experienced rebleeding within 5 days and 6 weeks after the intervention (P = .009). The cumulative 1-year survival rate was higher in the TIPS group than in the non-TIPS group (93.9% vs 78.6%, P = .01). The TIPS group had a higher incidence of hepatic encephalopathy within one year compared with the non-TIPS group (18.2% vs 4.3%, P = .026).

CONCLUSION

For patients with cirrhosis and active variceal bleeding who do not respond to high-dose vasoactive agents and require a balloon tamponade for hemostasis, TIPS may be an appropriate treatment choice.

Initial Experience With Endoscopic Ultrasound-guided Coil Placement for Pediatric Gastric Variceal Hemostasis

BACKGROUND

Gastric variceal (GV) bleeding is among the most morbid sequelae of portal hypertension, with mortality ranging from 30% to 50%. Pediatric data focused on endoscopic approaches to management are needed. The present study represents the first pediatric case series of endoscopic ultrasound (EUS)-guided coil placement within feeding vessels as monotherapy for management of GV bleeding.

METHODS

Using our prospectively maintained endoscopy database, we identified patients 18 years and younger who underwent EUS-guided coil placement for management of GV bleeding from 2008 to 2018. Demographics, indication, procedural interventions/findings, and available clinical outcomes data were analyzed.

RESULTS

Twelve patients (median age 15, range 11-18 years) underwent EUS-guided coil placement for GV bleeding. All had portal hypertension, with EV in 58.3% and prior GV bleeding with attempted endoscopic management in 75%. Coil placement was accomplished using a linear echoendoscope and a 19-gauge needle. A mean of 2.75 (± 0.43) coils were placed in each patient (4, 6, 8, and 10 mm Nester Embolization Coils, Cook Medical, Bloomington, Indiana, USA). Immediate hemostasis was achieved in all patients, and 25% of patients developed recurrent gastric varices at a median of 5.5 months following the initial EUS-guided coil placement (range 4-6 months) over the median 12 month follow-up period.

CONCLUSIONS

The present study establishes the feasibility and efficacy of EUS-guided coil placement as monotherapy for GV bleeding in children and adolescents. The technique was technically successful, with primary hemostasis achieved in all patients. EUS-guided embolization with coils may represent an alternative to current approaches for management of highly morbid GV bleeding.

Impact of variceal eradication on rebleeding and prognosis in cirrhotic patients undergoing secondary prophylaxis

BACKGROUND

Endoscopic therapy has been widely applied to prevent variceal rebleeding, but data addressing the effect of endoscopic variceal eradication (VE) are lacking. We aimed to clarify the clinical impact of VE and reveal the long-term incidence and mortality of gastrointestinal rebleeding.

METHODS

This prospective study included 228 cirrhotic patients who underwent secondary prophylaxis for variceal bleeding and achieved VE through a systematic procedure we proposed as endoscopic sequential therapy (EST). Rebleeding rates before and after VE were compared and cumulative incidence of rebleeding and mortality were calculated using the Kaplan-Meier method. A logistic regression model and P for trend were used to investigate the optimal time limit for VE.

RESULTS

During a median (interquartile range) follow-up duration of 33.0 (23.0-48.75) months, rebleeding was identified in 28 patients (12.3%) after VE and in 27 patients (11.8%) during endoscopic sessions. The cumulative incidence of rebleeding before and after VE was 8.4% and 1.8% at 6 months, and 14.9% and 4.0% at 1 year respectively (P<0.001). The long-term incidence of all-cause/variceal rebleeding following VE was 10.4%/9.1%, and 31.5%/23.5% at 2 and 5 years respectively. Eleven patients (4.8%) died and the 5-year mortality was 9.3%. VE achieved within 6 months was associated with fewer rebleeding events compared to VE achieved after 6 months (5.5% vs. 20.0%, P=0.002), while logistic regression revealed an overall increasing trend in the odds ratio of rebleeding (vs. patients with VE time ≤6 months) for patients with 6< VE time ≤12 months and VE time >12 months (P for trend <0.001).

CONCLUSIONS

VE further reduces rebleeding based on routine endoscopic prophylaxis and improves long-term prognosis. VE within 6 months seems to be the optimal timing and should therefore be advocated.

Endoscopic thermocoagulation hemostasis for acute non-varicose upper gastrointestinal hemorrhage: a randomized controlled study

OBJECTIVE

This study evaluated the application of the bipolar electrocoagulation catheter via a peripheral-to-central (3 + 1) technique, relative to directly pressing only at the center of the bleeding site (direct-stroke), to effect endoscopic hemostasis of acute non-varicose gastrointestinal bleeding (ANVUGIB).

METHODS

Patients (n = 148) with endoscopically diagnosed ANVUGIB were randomly apportioned to receive treatment by 3 + 1 (n = 78) or direct-stroke (n = 70) application of the bipolar electrocoagulation catheter. The 3 + 1 strategy required pressing at3 narrowly restricted sites equidistant peripheral and center to the site of bleeding. The rates of initial success, hemostasis time, and number of compressions were compared according to intention-to-treat (ITT) or per protocol (PP).

RESULTS

The ITT (PP) rate of initial hemostatic success in patients receiving the 3 + 1 catheter was 91.02% (95.9%); and for the direct-stroke group was 71.42% (76.9%). For Forrest IIa lesions specifically, these rates were respectively 91.70% (97.1%) and 63.9% (67.6%). The ITT (PP) hemostasis times of the 3 + 1 and direct-stroke groups were 10.96 ± 3.28 (10.65 ± 2.90) and 14.27 ± 6.58 (14.12 ± 6.67) min; and the number of compressions numbered 5.73 ± 1.98 (5.42 ± 1.46) and 6.47 ± 2.82 (6.16 ± 2.47).

CONCLUSION

During thermocoagulation treatment of ANVUGIB via bipolar electrocoagulation catheter, the 3 + 1 strategy showed a significantly higher rate of successful initial hemostasis relative to the direct-stroke technique, and shorter hemostasis time, with no increase in total procedural steps.

Association of portal venous system thrombosis with endoscopic variceal treatment: a systematic review and meta-analysis

The association of endoscopic variceal treatment (EVT) with the development of portal venous system thrombosis (PVST) in liver cirrhosis remains uncertain. A systematic review and meta-analysis aimed to investigate the incidence of PVST after EVT and to explore the association of EVT with the development of PVST in liver cirrhosis. All relevant studies were searched via the PubMed, EMBASE, and Cochrane Library databases. The incidence of PVST in patients treated with and without EVT was pooled. Risk ratios with 95% confidence intervals (CIs) were calculated. Heterogeneity among studies was calculated. Meta-regression, sensitivity, and subgroup analyses were used to analyze the source of heterogeneity. Thirteen studies involving a total of 833 patients were included. The pooled incidence of PVST after EVT was 10.4% (95% CI, 4.9-17.7%). There was a statistically significant heterogeneity (I2 = 83.3%, P < 0.0001). Meta-regression, sensitivity, and subgroup analyses did not find the source of heterogeneity. Four studies compared the incidence of PVST between patients treated with and without EVT. The incidence of PVST was significantly higher in the EVT group than that in the no-EVT group (risk ratio: 2.23; 95% CI, 1.11-4.49; P = 0.02). The heterogeneity was not statistically significant (I2 = 0%, P = 0.43). In conclusion, PVST after EVT may not be scare, and EVT may increase the risk of PVST in liver cirrhosis.

Treatment of upper gastrointestinal bleeding in 2020: New techniques and outcomes

The clinical outcome of upper gastrointestinal bleeding has improved due to advances in endoscopic therapy and standardized peri-endoscopy care. Apart from validating clinical scores, artificial intelligence-assisted machine learning models may play an important role in risk stratification. While standard endoscopic treatments remain irreplaceable, novel endoscopic modalities have changed the landscape of management. Over-the-scope clips have high success rates as rescue or even first-line treatments in difficult-to-treat cases. Hemostatic powder is safe and easy to use, which can be useful as temporary control with its high immediate hemostatic ability. After endoscopic hemostasis, Doppler endoscopic probe can offer an objective measure to guide the treatment endpoint. In refractory bleeding, angiographic embolization should be considered before salvage surgery. In variceal hemorrhage, banding ligation and glue injection are first-line treatment options. Endoscopic ultrasound-guided therapy is gaining popularity due to its capability of precise localization for treatment targets. A self-expandable metal stent may be considered as an alternative option to balloon tamponade in refractory bleeding. Transjugular intrahepatic portosystemic shunting should be reserved as salvage therapy. In this article, we aim to provide an evidence-based comprehensive review of the major advancements in endoscopic hemostatic techniques and clinical outcomes.

Noninvasive scores for the prediction of esophageal varices and risk stratification in patients with cirrhosis

The primary purpose of variceal screening in patients with cirrhosis is to detect gastroesophageal varices at high risk of hemorrhage and implement preventative intervention(s). It was previously recommended that all patients with cirrhosis undergo initial and periodic longitudinal variceal screening via upper endoscopy. However, there has been growing interest and methods to identify patients with cirrhosis who may not have clinically significant portal hypertension and therefore be unlikely to have varices requiring intervention or benefit from upper endoscopy. Because the population of patients with compensated advanced chronic liver disease continues to grow, it is neither beneficial nor cost-effective to perform endoscopic variceal screening in all patients. Therefore, there is ongoing research into the development of methods to non-invasively risk stratify patients with cirrhosis for the presence of high-risk esophageal varices and effectively limit the population that undergoes endoscopic variceal screening. This is particularly important and timely in light of increasing healthcare reform and barriers to healthcare. In this review, we discuss and compare, with respect to test characteristics and clinical applicability, the available methods used to non-invasively predict the presence of esophageal varices.

Clinical utility of viscoelastic testing in chronic liver disease: A systematic review

BACKGROUND

Conventional coagulation tests are widely used in chronic liver disease to assess haemostasis and to guide blood product transfusion. This is despite the fact that conventional tests do not reliably separate those with a clinically significant coagulopathy from those who do not. Viscoelastic testing such as thromboelastography (TEG) correlate with bleeding risk and are more accurate in identifying those who will benefit from blood product transfusion. Despite this, viscoelastic tests have not been widely used in patients with chronic liver disease outside the transplant setting.

AIM

To assess the utility of Viscoelastic Testing guided transfusion in chronic liver disease patients presenting with bleeding or who require an invasive procedure.

METHODS

PubMed and Google Scholar searches were performed using the key words “thromboelastography”, “TEG” or “viscoelastic” and “liver transplantation”, “cirrhosis” or “liver disease” and “transfusion”, “haemostasis”, “blood management” or “haemorrhage”. A full text review was undertaken and data was extracted from randomised control trials that evaluated the outcomes of viscoelastic test guided transfusion in those with liver disease. The study subjects, inclusion and exclusion criteria, methods, outcomes and length of follow up were examined. Data was extracted by two independent individuals using a standardized collection form. The risk of bias was assessed in the included studies.

RESULTS

A total of five randomised control trials included in the analysis examined the use of TEG guided blood product transfusion in cirrhosis prior to invasive procedures (n = 118), non-variceal haemorrhage (n = 96), variceal haemorrhage (n = 60) and liver transplantation (n = 28). TEG guided transfusion was effective in all five studies with a statistically significant reduction in overall blood product transfusion compared to standard of care. Four of the five studies reported a significant reduction in transfusion of fresh frozen plasma and platelets. Two studies showed a significant reduction in cryoprecipitate transfusion. No increased risk of bleeding was reported in the three trials where TEG was used perioperatively or prior to an invasive procedure. Two trials in the setting of cirrhotic variceal and non-variceal bleeding showed no difference in control of initial bleeding. In those with variceal bleeding, there was a statistically significant reduction in rate of re-bleeding at 42 d in the TEG arm 10% (vs 26.7% in the standard of care arm P = 0.012). Mortality data reported at various time points for all five trials from 6 wk up to 3 years was not statistically different between each arm. One trial in the setting of non-variceal bleeding demonstrated a significant reduction in adverse transfusion events in the TEG arm 30.6% (vs 74.5% in the control arm P < 0.01). In this study there was no significant difference in total hospital stay although length of stay in intensive care unit was reduced by an average of 2 d in the TEG arm (P = 0.012).

CONCLUSION

Viscoelastic testing has been shown to reduce blood product usage in chronic liver disease without compromising safety and may enable guidelines to be developed to ensure patients with liver disease are optimally managed.

Quality indicators in gastroscopy. Gastroscopy procedure

Within the project "Quality indicators in digestive endoscopy", pioneered by the Spanish Society for Digestive Diseases (SEPD), the objective of this research is to suggest the structure, process, and results procedures and indicators necessary to implement and assess quality in the gastroscopy setting. First, a chart was designed with the steps to be followed during a gastroscopy procedure. Secondly, a team of experts in care quality and/or endoscopy performed a qualitative review of the literature searching for quality indicators for endoscopic procedures, including gastroscopies. Finally, using a paired analysis approach, a selection of the literature obtained was undertaken. For gastroscopy, a total of nine process indicators were identified (one preprocedure, eight intraprocedure). Evidence quality was assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification scale.

Positive consequences of splenectomy for patients with schistosomiasis-induced variceal bleeding

BACKGROUND

Patients with hepatic schistosomiasis are at high risk of gastroesophageal variceal bleeding, which is highly torrential and life threatening. This study aimed to assess the effects of splenectomy on patients with schistosomiasis-induced variceal bleeding, especially those influences related to overall survival (OS) rate.

METHODS

From January 2005 to December 2018, 112 patients with schistosomiasis-induced varices were enrolled. In that period, all the patients with hepatic schistosomiasis who received endoscopic treatment for primary and secondary prophylaxis of gastroesophageal variceal bleeding were found eligible. The patients were divided into splenectomized group (n = 44, 39.3%) and control group (n = 68, 60.7%).

RESULTS

Multivariate regression analysis of OS showed that splenectomy, hepatic carcinoma, and times of endoscopic treatment were independent prognostic factors for OS. Kaplan-Meier analysis revealed that the 5-year OS rate was 82.7% in splenectomized group versus 53.2% in control group (P = 0.037). The rate of no recurrence of variceal bleeding during 5-year (56.8% vs. 47.7%, P = 0.449) indicated that there was no significant difference between the two groups. Patients who received splenectomy had increased risk of portal vein thrombosis (52.3% vs. 29.4%, P = 0.012) and decreased proportion of severe ascites (20.5% vs 50.0%, P = 0.002).

CONCLUSION

Splenectomy prior to endoscopic treatment provides a superior long-term survival for patients with schistosomiasis-induced variceal bleeding.

The role of antibiotics in upper gastrointestinal bleeding among cirrhotic patients without major complications after endoscopic hemostasis

BACKGROUND AND AIM

Antibiotic prophylaxis should be instituted for cirrhotic patients with upper gastrointestinal bleeding (UGIB), but the benefit on compensated patients remains undetermined. We aimed to compare the clinical outcomes between cirrhotic patients without major complications with UGIB with and without antibiotic prophylaxis.

METHODS

We conducted this population-based cohort study by using Taiwanese Longitudinal Health Insurance Database 2000 (LHID2000, between 1997 to 2013), aged 18 years or older with a hospital discharge diagnosis of cirrhosis (n = 64,506), UGIB (n = 7,784), and endoscopic therapy (n = 2,292). After strict exclusions, 1205 patients were enrolled and were divided into antibiotic exposure (n = 558) and non-exposure (n = 647) groups. The outcomes were rebleeding and mortality.

RESULTS

After completing the analysis adjusted by death, the rebleeding rates within 4 weeks were significantly lower in patients with antibiotic prophylaxis (3.05% versus 6.03%, P = 0.0142) and those with endoscopic therapy (0.72% vs 3.09%, P = 0.0033) but not significant after 3 months and onwards. Male patients aged > 55, high CCI score ≧ 4, and UGIB of variceal etiologies were benefited from rebleeding. The use of antibiotics did not significantly impact 6-week mortality (adjusted hazard ratio: 1.07, 95%CI: 0.41~2.75; P = 0.8943). Old age, multiple comorbidities, and UGIB of variceal etiologies were risk factors of all-cause mortality.

CONCLUSIONS

The current study suggested that cirrhotic patients without major complications who suffered from UGIB were benefited by the use of antibiotics to prevent rebleeding within 4 weeks after endoscopic treatment of UGIB especially for those with age > 55, high CCI score ≧ 4, and UGIB of variceal etiologies.
