Secondary prophylaxis for esophageal variceal bleeding

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.

The prognostic evaluation of ALBI score in endoscopic treatment of esophagogastric varices hemorrhage in liver cirrhosis

To analyze the independent risk factors for recurrent bleeding and death within 1 year after endoscopic treatment of esophagogastric varices hemorrhage (EGVB) in patients with liver cirrhosis, and to validate the predictive value of ALBI score for recurrent bleeding and death within 1 year after endoscopic treatment of EGVB in patients with liver cirrhosis. A total of 338 patients with EGVB who received endoscopic treatment for the first time in the Department of Gastroenterology, First Affiliated Hospital of Nanchang University from January 1, 2016 to March 1, 2020 were selected. A database was established to analyze the patients' demographic data, surgical variables and postoperative outcomes. All patients were contacted and followed up to verify the predictive value of ALBI score for recurrent bleeding and mortality. 130 patients had rebleeding within 1 year after surgery (38.5%). 66 patients died within 1 year after surgery (19.5%). Patients with ALBI grade 3 had significantly higher rebleeding and mortality rates than those with grades 1 and 2. The AUC was used to compare the predictive value of the four scores for rebleeding and mortality within one year after endoscopic surgery. Both ALBI scores had the largest AUC. The ALBI score has certain predictive value for rebleeding and mortality within 1 year after endoscopic therapy in patients with cirrhotic EGVB.

Mushroom Sign: Complete Esophageal Obstruction After Esophageal Variceal Band Ligation With Successful Removal of Variceal Band

Esophageal varices due to portal hypertension are treated with endoscopic variceal band ligation (EVBL), a minimally invasive procedure with potential complications, such as pain, bleeding, and stricture formation. Rarely, complete esophageal obstruction can occur secondary to edema of the mucosa. Most cases can be managed conservatively, but intervention is necessary for severe symptoms with a risk for aspiration and airway compromise. Since EVBL is such a common procedure, it is important for clinicians to be aware of this rare but severe complication. An 80-year-old woman presented with severe dysphagia and chest discomfort after a recent EVBL. Esophagogastroduodenoscopy revealed esophageal mucosal edema and complete obstruction of the esophageal lumen. The band was removed with a loop cutter with subsequent balloon dilation to relieve the obstruction.

Management of severe peri-operative bleeding: Guidelines from the European Society of Anaesthesiology and Intensive Care: Second update 2022

BACKGROUND

Management of peri-operative bleeding is complex and involves multiple assessment tools and strategies to ensure optimal patient care with the goal of reducing morbidity and mortality. These updated guidelines from the European Society of Anaesthesiology and Intensive Care (ESAIC) aim to provide an evidence-based set of recommendations for healthcare professionals to help ensure improved clinical management.

DESIGN

A systematic literature search from 2015 to 2021 of several electronic databases was performed without language restrictions. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used to assess the methodological quality of the included studies and to formulate recommendations. A Delphi methodology was used to prepare a clinical practice guideline.

RESULTS

These searches identified 137 999 articles. All articles were assessed, and the existing 2017 guidelines were revised to incorporate new evidence. Sixteen recommendations derived from the systematic literature search, and four clinical guidances retained from previous ESAIC guidelines were formulated. Using the Delphi process on 253 sentences of guidance, strong consensus (>90% agreement) was achieved in 97% and consensus (75 to 90% agreement) in 3%.

DISCUSSION

Peri-operative bleeding management encompasses the patient's journey from the pre-operative state through the postoperative period. Along this journey, many features of the patient's pre-operative coagulation status, underlying comorbidities, general health and the procedures that they are undergoing need to be taken into account. Due to the many important aspects in peri-operative nontrauma bleeding management, guidance as to how best approach and treat each individual patient are key. Understanding which therapeutic approaches are most valuable at each timepoint can only enhance patient care, ensuring the best outcomes by reducing blood loss and, therefore, overall morbidity and mortality.

CONCLUSION

All healthcare professionals involved in the management of patients at risk for surgical bleeding should be aware of the current therapeutic options and approaches that are available to them. These guidelines aim to provide specific guidance for bleeding management in a variety of clinical situations.

PPI efficacy in the reduction of variceal bleeding incidence and mortality, a meta-analysis

Objective

To review the efficacy and safety of proton pump inhibitors (PPIs) in gastroesophageal varices (GEVs).

Methods

We searched PubMed MEDLINE, Scopus, and Web of Science for studies that measured the effect of PPI for prophylaxis and treatment of post-band ligation ulcers up to July 20, 2021. We included studies that measured the effect of PPI as treatment or prophylaxis for post-band ligation ulcers; articles that were published in peer-reviewed international journals and had enough data for qualitative and quantitative analysis were included with no language restriction. Heterogeneity was evaluated using the inconsistency (I2) and chi-squared (χ2) test. I2 > 50% was considered substantial heterogeneity in the studies, and a P value less than 0.05 was considered statistically significant. The data was continuous, and we used the standardized mean difference (MD) and risk ratio (RR) with a 95% confidence interval to assess the estimated effect measure.

Results

A total of 7 studies with 2030 patients were included in our study of which 1480 participants were males (72%) and 550 females (18%). Mean age was 59.7 years old. Rebleeding post-band ligation was compared between PPI and placebo with significant favor for PPI (p = 0.00001). The pooled risk ratio was 0.53 (95% CI of 0.41, 0.68); furthermore, bleeding-related death at a 1-month period was compared between PPI and placebo with significant favor for PPI (p = 0.00001). The pooled risk ratio was significant at 0.33 (95% CI of 0.20, 0.53). The length of hospital stay postoperative was compared between PPI and placebo with cumulative mean difference of 0.13 (95% CI of −1.13, 1.39), yet without significance.

Conclusions

The study suggests a twofold reduction in the risk of bleeding and a threefold reduction in the risk of bleeding-related death with the use of PPI following EVL.

A Liver Stiffness Measurement-Based Nomogram Predicts Variceal Rebleeding in Hepatitis B-Related Cirrhosis

Background

Cirrhosis esophageal variceal rebleeding is a major complication of chronic cirrhosis. The hepatic venous pressure gradient (HVPG) can predict the risk of rebleeding in patients with cirrhosis and has a good correlation with liver stiffness measurement (LSM). However, there are currently few studies based on liver stiffness to predict the risk of rebleeding in patients with liver cirrhosis. This study is aimed at exploring whether liver stiffness can predict rebleeding in patients with hepatitis B virus-related cirrhosis and developing an easy-to-use nomogram for predicting the risk of rebleeding in patients with liver cirrhosis undergoing secondary prevention.

Methods

A prospective analysis of 289 cirrhosis patients was performed. Univariate and multivariate analyses were used to identify independent prognostic factors to create a nomogram. The performance of the nomogram was evaluated by using a bootstrapped-concordance index and calibration plots.

Results

Use of a nonselective beta-blocker (NSBB) drug, LSM, hemoglobin, and platelet count were identified as factors that could predict rebleeding. We created a nomogram for rebleeding in cirrhosis by using these risk factors. The predictive ability of the nomogram was assessed by the C-index (0.772, 95% CI 0.732–0.822). The results of the calibration plots showed that the actual observation and prediction values obtained by the nomogram had good consistency.

Conclusions

LSM can predict the risk of rebleeding in patients with cirrhosis, while the nomogram is a conventional tool for doctors to facilitate a personalized prognostic evaluation.

Number of endoscopic sessions to eradicate varices identifies high risk of rebleeding in cirrhotic patients

Background and aims

Risk stratification to identify patients with high risk of variceal rebleeding is particularly important in patients with decompensated cirrhosis. In clinical practice, eliminating gastroesphageal varices thoroughly after sequential endoscopic treatment reduces the rebleeding rate, however, no simple method has been build to predict high risk of variceal rebleeding. We conducted this study to explore the value of the number of endoscopic sessions required to eradicate gastroesphageal varices in identifying high risk of rebleeding.

Patients and methods

Consecutive cirrhotic patients received sequential endoscopic therapy between January 2015 and March 2020 were enrolled. Endoscopic treatment was performed every 1–4 weeks until the eradication of varices. The primary endpoint was variceal rebleeding.

Results

A total of 146 patients were included of which 60 patients received standard therapy and 86 patients underwent sequential endoscopic treatment alone. The cut-off value of the number of sequential endoscopic sessions is 3.5 times. Variceal rebleeding was significant higher in patients with endoscopic sessions > 3 times versus ≤ 3 times (61.5% vs. 17.5%, p < 0.001). Variceal rebleeding of patients with endoscopic sessions ≤ 3 times was significant lower than patients with > 3 times in group of standard therapy (19.6% vs. 88.9%, p < 0.001) and endoscopic therapy (15.9% vs. 47.1%, p = 0.028) respectively.

Conclusion

The number of sequential endoscopic sessions required to eradicate the varices is related to the risk of variceal rebleeding in patients with cirrhosis. If three times of endoscopic treatment can not eradicate the varices, a more aggressive treatment such as TIPS should be seriously considered.

Endoscopic therapy + β-blocker vs. covered transjugular intrahepatic portosystemic shunt for prevention of variceal rebleeding in cirrhotic patients with hepatic venous pressure gradient ≥16 mmHg

BACKGROUND AND OBJECTIVE

Currently, monitoring hepatic venous pressure gradient (HVPG) have been proved to be the best predictor for the risk of variceal bleeding. We performed the study to evaluate the effect of endoscopic therapy + β-blocker vs. covered transjugular intrahepatic portosystemic shunt (TIPS) for the prevention of variceal rebleeding in cirrhotic patients with HVPG ≥16 mmHg.

METHODS

Consecutive cirrhotic patients with HVPG ≥16 mmHg treated with endoscopic therapy + β-blocker or covered TIPS for variceal bleeding were retrospectively gathered between April 2013 and December 2018. The variceal rebleeding rate, survival, and incidence of overt hepatic encephalopathy (OHE) were compared.

RESULTS

A total of 83 patients were analyzed, of which 46 received endoscopic therapy + β-blocker and 37 covered TIPS. During a median follow-up of 12.0 months, the rebleeding rate (32.6 vs. 10.8%, P = 0.017) and rate of OHE (2.2 vs. 27.0%, P = 0.001) showed significant differences between the two groups, while liver transplantation-free survival (93.5 vs. 94.6%, P = 0.801) was similar. Preoperative and postoperative Child-Turcotte-Pugh scores were similar in either group. In addition, no significant differences of rebleeding rate (25.0 vs. 21.3%, P = 0.484) and survival (97.2 vs. 91.5%, P = 0.282) were observed between patients with 16 mmHg ≤ HVPG < 20 mmHg and HVPG ≥ 20 mmHg.

CONCLUSION

Covered TIPS was more effective than endoscopic therapy + β-blocker in preventing rebleeding in patients with HVPG ≥16 mmHg but did not improve survival. TIPS also induce more OHE.

Increase in Free Hepatic Venous Pressure Response to Beta-Blockers Predicts Variceal Bleeding in Cirrhotic Patients

Background and Aims

Nonselective beta-blockers (NSBBs) are the main drug to prevent portal hypertension. It could alter free hepatic venous pressure (FHVP); however, the significance is unknown. This prospective study was to explore the change of FHVP after use of NSBBs and its predictive value for gastroesophageal varices (GOV) bleeding in cirrhotic patients. Patients and Methods. Cirrhotic patients with medium-large GOV between September 2014 and January 2019 were enrolled. After initial hepatic venous pressure gradient (HVPG) measurement, patients received oral NSBBs. Seven days later, the secondary HVPG was examined to evaluate the FHVP alteration and hemodynamic response. The variceal bleeding between patients with FHVP increased and decreased/unchanged was compared.

Results

A total of 74 patients were enrolled, and 62 patients completed the secondary HVPG measurement and was followed up. The cumulative bleeding rate was significantly higher in patients with FHVP increased ≥ 1.75 mmHg than those with FHVP decreased/unchanged (54.5% vs. 22.5%, p = 0.021), while there was no significant difference in bleeding between HVPG responders and nonresponders (32.6% vs. 37.5%, p = 0.520). For HVPG responders, variceal bleeding in patients with FHVP increased ≥ 1.75 mmHg was significantly more than that in patients with FHVP decreased/unchanged (57.9% vs. 28.6%, p = 0.041). Cox regression analysis showed that change of FHVP was an independent predictor of variceal bleeding.

Conclusion

Increase ≥ 1.75 mmHg in FHVP responding to beta-blockers in cirrhotic patients with GOV indicates high risk of variceal bleeding. Besides HVPG response, change of FHVP should also be valued in hemodynamic evaluation to beta-blockers. This trial is registered with Chinese Clinical Trial Registry ChiCTR-IPR-17012836.

Proton-pump-inhibitor use associated with lower short-term rebleeding and mortality in patients receiving esophageal variceal band ligation: a retrospective cohort study

BACKGROUND

The impact of proton-pump inhibitor (PPI) therapy on subsequent hemorrhage and mortality after variceal hemorrhage is unclear.

AIM

Evaluate the associations of PPI use with upper gastrointestinal bleeding (UGIB) and death within 30 days of undergoing esophageal variceal band ligation (EBL) separately in inpatient and outpatient settings.

METHODS

Retrospective review of cirrhotic patients with variceal hemorrhage who underwent EBL between 2005 and 2018. Endoscopic findings, PPI use at admission (inpatients only), PPI use at discharge (inpatients and outpatients), and adverse outcomes data (liver transplant, UGIB, transjugular intrahepatic portosystemic shunt, and death within 30 days of discharge or death during hospitalization) were reviewed.

RESULTS

A total of 446 patients (164 inpatients, 282 outpatients) were included. The most commonly observed outcomes were death within 30 days of discharge in inpatients (12.8%), UGIB within 30 days of discharge in inpatients (21.3%), and UGIB within 30 days of discharge in outpatients (8.5%). For inpatients, prescription of PPI at discharge was associated with a lower risk of bleeding within 30 days (odds ratio: 0.30, P = 0.025) and death within 30 days (odds ratio = 0.16, P = 0.002). No other significant associations of PPI with death or UGIB were reported.

CONCLUSION

Post-EBL PPI therapy is associated with reduced risk of bleeding and death within 30 days after variceal hemorrhage in hospitalized patients.

Role of band ligation for secondary prophylaxis of variceal bleeding

AIM

To summarize and critically examine the role of band ligation in secondary prophylaxis of variceal bleeding in patients with cirrhosis.

METHODS

A literature review was performed using the MEDLINE and PubMed databases. The search terms consisted of the words “endoscopic band ligation” OR “variceal band ligation” OR “ligation” AND “secondary prophylaxis” OR “secondary prevention” AND “variceal bleeding” OR “variceal hemorrhage” AND “liver cirrhosis”. The data collected from relevant meta-analyses and from the most recent randomized studies that were not included in these meta-analyses were used to evaluate the role of endoscopic band ligation in an effort to demonstrate the most recent advances in the treatment of esophageal varices.

RESULTS

This study included 11 meta-analyses published from 2002 to 2017 and 10 randomized trials published from 2010 to 2017 that evaluated the efficacy of band ligation in the secondary prophylaxis of variceal bleeding. Overall, the results proved that band ligation was superior to endoscopic sclerotherapy. Moreover, the use of β-blockers in combination with band ligation increased the treatment effectiveness, supporting the current recommendations for secondary prophylaxis of variceal bleeding. The use of transjugular intrahepatic portosystemic shunt was superior to combination therapy regarding rebleeding prophylaxis, with no difference in the survival rates; however, the results concerning the hepatic encephalopathy incidence were conflicting. Recent advances in the management of secondary prophylaxis of variceal bleeding have targeted a decrease in portal pressure based on the pathophysiological mechanisms of portal hypertension.

CONCLUSION

This review suggests that future research should be conducted to enhance current interventions and/or to develop innovative treatment options with improved clinical endpoints.

Consensus conference on TIPS management: Techniques, indications, contraindications

The trans jugular intrahepatic Porto systemic shunt (TIPS) is no longer viewed as a salvage therapy or a bridge to liver transplantation and is currently indicated for a number of conditions related to portal hypertension with positive results in survival. Moreover, the availability of self-expandable polytetrafluoroethylene (PTFE)-covered endoprostheses has dramatically improved the long-term patency of TIPS. However, since the last updated International guidelines have been published (year 2009) new evidence have come, which have open the field to new indications and solved areas of uncertainty. On this basis, the Italian Association of the Study of the Liver (AISF), the Italian College of Interventional Radiology-Italian Society of Medical Radiology (ICIR-SIRM), and the Italian Society of Anesthesia, Analgesia and Intensive Care (SIAARTI) promoted a Consensus Conference on TIPS. Under the auspices of the three scientific societies, the consensus process started with the review of the literature by a scientific board of experts and ended with a formal consensus meeting in Bergamo on June 4th and 5th, 2015. The final statements presented here were graded according to quality of evidence and strength of recommendations and were approved by an independent jury. By highlighting strengths and weaknesses of current indications to TIPS, the recommendations of AISF-ICIR-SIRM-SIAARTI may represent the starting point for further studies.
