Safety and efficacy of common endoscopic treatments in patients with decompensated liver cirrhosis

Predictive Factors of Post-ERCP Hepatic Decompensation in Patients with Cirrhosis: A Retrospective Case-Control Study

BACKGROUND AND AIM

Endoscopic retrograde cholangiopancreatography (ERCP) is a crucial diagnostic and therapeutic procedure in patients with cirrhosis; however, it carries the risk of post-procedural hepatic decompensation. This study aims to identify predictive factors associated with post-ERCP hepatic decompensation in patients with cirrhosis to better inform clinical decision-making and minimize adverse outcomes.

METHODS

A retrospective analysis was conducted on patients with cirrhosis undergoing ERCP. Clinical, biochemical, and procedural variables were evaluated to determine their association with hepatic decompensation. Multivariate analysis was performed to identify independent predictors.

RESULTS

A total of 277 patients with cirrhosis who underwent an ERCP were included. The cohort had a mean age of 63.4 years, with a male predominance (65.3%) and various etiologies of cirrhosis, including alcohol-related (39.3%) and hepatitis C (11.4%). Post-ERCP complications occurred in 26.7% of patients. The most common complications were hepatic decompensation events (18.4%), sepsis (10.8%), and cholangitis (6.1%). Patients with complications had significantly higher baseline MELD scores, INR, chronic kidney disease (CKD) and history of ascites, hepatic encephalopathy, and hepatorenal syndrome (HRS). A Multivariate analysis revealed that factors such as higher MELD score, ascites, hepatic encephalopathy, and stent placement were associated with post-ERCP complications. Subgroup analyses indicated that patients who developed hepatic decompensation events (ascites, SBP, or HRS) had a more severe liver dysfunction at baseline, as reflected by a higher MELD score and INR, and prior episodes of ascites and hepatic encephalopathy.

CONCLUSION

Pre-procedural liver function parameters and procedural factors are crucial predictors of post-ERCP hepatic decompensation in patients with cirrhosis. Key risk factors include higher MELD score, CKD, history of ascites, and hepatic encephalopathy. Careful pre-procedural evaluation and management are essential to reduce these risks.

Endoscopic resection of early esophageal neoplasia in patients with esophageal varices: a systematic review

Although endoscopic resection (ER) is recommended as first-choice treatment for early esophageal neoplasia, patients with esophageal varices are considered a high-risk group owing to an increased risk of bleeding. This systematic review aimed to evaluate the effectiveness and safety of ER in this specific patient category.We searched for studies reporting on clinical outcomes of ER in the presence of esophageal varices, irrespective of study design or follow-up time. End points included the incidence of prophylactic measures to reduce the risk of variceal hemorrhage, radical and curative resection rates, and adverse events.After screening 2371 studies, 42 studies (including our own unpublished cohort) with a total of 186 patients were included in this systematic review. Endoscopic band ligation (72/186; 39%) and endoscopic injection sclerotherapy (22/186; 12%) were the prophylactic measures most widely adopted to eradicate varices prior to ER. Other frequently described prophylactic measures included direct varix coagulation during ER (18/186; 10%) and the placement of a transjugular intrahepatic portosystemic shunt prior to ER (9/186; 5%). While the radical and curative resection rates were high (86% and 72%, respectively), the periprocedural and delayed bleeding risks were reported to be relatively low (6% and 3%, respectively). In all studies, no procedure-related mortality was observed.ER appeared to be a safe and effective treatment option in selected patients with concurrent early esophageal neoplasia and esophageal varices, provided that a tailored approach of adequate prophylactic measures to prevent bleeding is applied.

Applicability of Child-Turcotte-Pugh Score in Anticipating Post-ERCP Adverse Events in Patients With Cirrhosis: A Systematic Review and Meta-analysis

Limited objective data exist on the comparison of post-endoscopic retrograde cholangiopancreatography (ERCP) complications in patients with cirrhosis based on the severity of the disease. We evaluated the effectiveness of the Child-Turcotte-Pugh (CTP) score system in anticipating the risk of post-ERCP complications in patients with cirrhosis. The PubMed, Scopus, Embase, and Cochrane databases were searched from inception through September 2022 to identify studies comparing post-ERCP complications in patients with cirrhosis based on CTP score. Odds ratios (ORs) and their associated 95% CIs were pooled using a random-effect model to calculate effect size. The reference group for analysis was the CTP class C patient group. Seven studies comprising 821 patients who underwent 1068 ERCP procedures were included. The CTP class C patient population exhibited a higher risk of overall post-ERCP adverse events compared with those with class A or B (OR: 2.87, 95% CI: 1.77-4.65, P = 0.00 and OR: 2.02, 95% CI: 1.17-3.51, P = 0.01, respectively). Moreover, CTP class B patients had a significantly higher complication rate than CTP class A patients (OR: 1.62, 95% CI: 1.04-2.53, P = 0.03). However, no statistically significant differences were found in the occurrence of specific types of complications, including bleeding, pancreatitis, cholangitis, perforation, or mortality across the three CTP groups. We demonstrated that the CTP classification system is a reliable predictor of ERCP complications in patients with cirrhosis. Consequently, caution should be exercised when performing ERCP in patients classified as CTP class C.

Endoscopic Submucosal Dissection for Treatment of Early-Stage Cancer or Precancerous Lesion in the Upper Gastrointestinal Tract in Patients with Liver Cirrhosis

(1) Background: Endoscopic submucosal dissection (ESD) has been widely accepted as the standard method for treating early-stage cancer or precancerous lesions in the upper gastrointestinal tract; however, it may be difficult in patients with liver cirrhosis due to clinical challenges such as coagulation dysfunction, presence of gastroesophageal varices, etc. We aimed to demonstrate the safety and efficacy of ESD in these populations. (2) Methods: The clinical data of patients were retrospectively collected and analyzed. Inclusion criteria of the study were: a. patients with liver cirrhosis; b. patients who underwent ESD; c. patients who were diagnosed with early-stage cancer or precancerous lesions in the upper gastrointestinal tract. (3) Results: Eight patients were enrolled from April 2019 to April 2023, of whom three were male and five were female, with ages ranging from 43 to 70 years old. Seven lesions were located in the stomach and one other lesion was in the esophagus. ESD was performed successfully in all eight patients, and the resected lesion size ranged from 2 to 6 cm. Only one patient encountered postoperative complications, namely, chest pain and fever. No recurrence was noticed during a follow-up of 3 to 45 months. (4) Conclusions: ESD may serve as a safe and effective method for treating upper gastrointestinal early-stage cancer or precancerous lesions in patients with liver cirrhosis.

Safety of endoscopic retrograde cholangiopancreatography (ERCP) in cirrhosis compared to non-cirrhosis and effect of Child-Pugh score on post-ERCP complications: a systematic review and meta-analysis

BACKGROUND/AIMS

The safety of endoscopic retrograde cholangiopancreatography (ERCP) in hepatic cirrhosis and the impact of Child-Pugh class on post-ERCP complications need to be better studied. We investigated the post-ERCP complication rates in patients with cirrhosis compared with those without cirrhosis.

METHODS

We conducted a literature search of relevant databases to identify studies that reported post-ERCP complications in patients with hepatic cirrhosis.

RESULTS

Twenty-four studies comprising 28,201 patients were included. The pooled incidence of post-ERCP complications in cirrhosis was 15.5% (95% confidence interval [CI], 11.8%-19.2%; I2=96.2%), with an individual pooled incidence of pancreatitis 5.1% (95% CI, 3.1%-7.2%; I2=91.5%), bleeding 3.6% (95% CI, 2.8%-4.5%; I2=67.5%), cholangitis 2.9% (95% CI, 1.9%-3.8%; I2=83.4%), and perforation 0.3% (95% CI, 0.1%-0.5%; I2=3.7%). Patients with cirrhosis had a greater risk of post-ERCP complications (risk ratio [RR], 1.41; 95% CI, 1.16-1.71; I2=56.3%). The risk of individual odds of adverse events between cirrhosis and non-cirrhosis was as follows: pancreatitis (RR, 1.25; 95% CI, 1.06-1.48; I2=24.8%), bleeding (RR, 1.94; 95% CI, 1.59-2.37; I2=0%), cholangitis (RR, 1.15; 95% CI, 0.77-1.70; I2=12%), and perforation (RR, 1.20; 95% CI, 0.59-2.43; I2=0%).

CONCLUSION

Cirrhosis is associated with an increased risk of post-ERCP pancreatitis, bleeding, and cholangitis.

Incidence and Cross-Continents Differences in Endoscopic Retrograde Cholangiopancreatography Outcomes Among Patients With Cirrhosis: A Systematic Review and Meta-Analysis

Background

There are conflicting data on the frequency and variability of endoscopic retrograde cholangiopancreatography (ERCP) outcomes in patients with cirrhosis. Our aim was to systematically review the literature on the incidence of post-ERCP adverse events in cirrhotic patients and to examine the differences across continents.

Methods

We searched PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases to identify studies reporting adverse events after ERCP in patients with cirrhosis from conception to September 30, 2022. The random effects model was used to calculate odds ratios (ORs), mean differences (MDs), and confidence intervals (CIs). A P value < 0.05 was considered statistically significant. Heterogeneity was assessed using the Cochrane Q-statistic (I²).

Results

Twenty-one studies that included 2,576 cirrhotic patients and 3,729 individual ERCPs were analyzed. The pooled overall rate of adverse events after ERCP in patients with cirrhosis was 16.98% (95% CI: 13.06-21.29%, P < 0.001, I² = 86.55%). ERCPs performed in Asia had the highest ERCP adverse events with an overall complication rate of 19.90%, while the lowest overall adverse events were in North America at 13.04%. The pooled post-ERCP bleeding, pancreatitis, cholangitis and perforation were 5.10% (95% CI: 3.33-7.19%, P < 0.001, I² = 76.79%), 3.21% (95% CI: 2.20-5.36%, P = 0.03, I² = 42.25%), 3.02% (95% CI: 1.19-5.52%, P < 0.001, I² = 87.11%), and 0.12% (95% CI: 0.00 - 0.45, P = 0.26, I² = 15.76%), respectively. The pooled post-ERCP mortality rate was 0.22% (95% CI: 0.00-0.85%, P = 0.01, I² = 51.86%).

Conclusions

This meta-analysis shows that the overall complication rates after ERCP, bleeding, pancreatitis, and cholangitis are high in patients with cirrhosis. Because cirrhotic patients are more likely to have post-ERCP complications, with significant cross-continent variations, the risks and benefits of ERCP in this patient population should be carefully considered.
