The Changing Scenario of Screening and Surveillance of Esophageal Varices

Role of liver transient elastography in detecting cirrhosis with esophageal and gastric varices and evaluating variceal severity

OBJECTIVE

To explore the application and clinical value of liver transient elastography (TE) in diagnosing and assessing the degree of liver cirrhosis combined with esophageal and gastric varices (EGV).

METHODS

We chose 136 patients with cirrhosis and EGV admitted to the Liver Disease Department of our hospital from December 2022 to December 2024. The patients were divided into mild EGV (n = 71), moderate EGV (n = 40), and severe EGV (n = 25) based on the gastroscopic results, and another 50 cases of healthy physical examination at the same period were admitted into the control group. All cases underwent liver TE, biochemical parameters, and immune parameters examination to observe the diagnostic efficacy of liver TE in cirrhosis combined with EGV and the degree of varices.

RESULTS

The differences in TBIL, ALT, AST, PTA, and other biochemical parameters between all of groups were not statistically significant (P > 0.05). The differences were not statistically significant for the four groups of IgM, IgG, and other immune indices (P > 0.05). There was no significant difference in blood flow among these groups (P > 0.05). The interior diameter (ID) of the portal vein, blood flow velocity, and liver stiffness values were significant (P < 0.05). Portal vein ID, blood velocity, and liver stiffness values showed well diagnostic efficacy in cirrhosis with EGV, and liver stiffness values were the best in evaluating cirrhosis with EGV (P < 0.05). Liver stiffness values were more effective in assessing the degree of varices in cirrhosis combined with EGV and the best in diagnosing cirrhosis combined with severe EGV (P < 0.05).

CONCLUSION

The application of liver TE has a high value in diagnosing cirrhosis combined with EGV and their degree of varices, especially in identifying severe curves, which has good clinical value.

Screening and surveillance of oesophageal varices in patients with HCV-positive liver cirrhosis successfully treated by direct-acting antiviral agents

BACKGROUND & AIMS

limited evidence is available to guide hepatologists regarding endoscopic surveillance of oesophageal varices (EV) in Hepatitis C Virus (HCV)-positive cirrhotic patients achieving a sustained virologic response. To address these issues, we conducted a long-term prospective study on 427 HCV-positive cirrhotic patients successfully treated by Direct Antiviral Agents (DAAs).

METHODS

Patients were divided into two groups according to their baseline Baveno VI status: Group 1 (92, 21.5%, favourable Baveno VI status) and Group 2 (335, 78.5%, unfavourable Baveno VI status). Each patient underwent baseline endoscopy and was endoscopically monitored for a median follow-up of 65.2 months according to Baveno VI recommendations.

RESULTS

About 4.3% of Group 1 patients showed baseline EV compared with 30.1% of Group 2 patients (p < .0001). No patients belonging to Group 1 without baseline EV developed EV at follow-up endoscopy compared with 6.5% in Group 2 patients (p = .02); 69/107 (64.5%) patients with baseline EV showed small varices. During the endoscopic follow-up, EV disappeared/improved in 36 (33.6%), were stable in 39 (36.4%) and worsened in 32 (29.9%) patients, all belonging to Group 2 (p = .001). Improvement in Baveno VI status was observed in 118/335 (35.2%, p < .0001) of Group 2 patients and among those without pre-therapy EV, none developed EV throughout the follow-up.

CONCLUSIONS

HCV-positive cirrhotic patients cured by DAAs showing baseline favourable Baveno VI status and no worsening during follow-up can safely avoid endoscopic screening and surveillance. Patients having unfavourable Baveno VI status without baseline EV who improve their status may suspend further endoscopic surveillance.

Postsustained Virological Response Management in Hepatitis C Patients

The introduction of direct-acting antiviral agents (DAA) has revolutionized management and care of patients with chronic hepatitis C virus (HCV) infection, leading to cure rates higher than 90% in patients with advanced liver disease as well. Viral eradication has been associated with longer survival, reduced mortality from both hepatic and extrahepatic causes, improvement in liver function, and reduced incidence of HCV-related extrahepatic diseases. While patients with mild fibrosis can safely be discharged after achievement of a sustained virological response, patients with advanced fibrosis and cirrhosis remain at risk of developing complications of liver disease, thus requiring regular and life-long surveillance. Major complications of cirrhosis that need to be monitored are hepatocellular carcinoma onset and development or progression of clinically significant portal hypertension.
