Patients with early-stage cirrhosis may also experience an enlargement of the portal vein. At this time, patients will need to complete related auxiliary examinations, such as electronic gastroscopy and abdominal color ultrasound, to rule out other complications caused by cirrhosis, such as esophageal and gastric variceal bleeding, or ascites associated with cirrhosis. It is crucial for early-stage cirrhosis patients to identify the cause as soon as possible and undergo etiological treatment, which sometimes can be very effective. For alcohol-related cirrhosis, abstaining from alcohol is necessary. If the cause is viral, such as chronic hepatitis B, antiviral treatments like entecavir are required.
