Brief Summary:
The purpose of the study is to compare the effect of HVPG-guided individualized therapy and non-HVPG guided traditional therapy in cirrhotic patients for secondary prophylaxis.

Condition or disease Intervention/treatment Phase
Gastroesophageal Varices Cirrhosis Procedure: HVPG-guided therapy Other: routine therapy Drug: Carvedilol Phase 4

Detailed Description:
The study is a randomized controlled trial of Zelen-design. Patients randomly enter two treatment groups: 1) the HVPG group and 2) the non-HVPG group. Treatment allocation is by block randomization with an equal number for both groups. The results are concealed in opaque envelopes.After randomization, patients will have a second chance to decide if they want to stay in the current group.Patients can switch to another group according to their will. If they are in the HVPG group，they will receive HVPG measurement before treatment. If they are in the non-HVPG group, they start treatment without HVPG measurement and receive endoscopic treatment plus Carvedilol.The mortality rate and rebleeding rate will be analyzed.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: HVPG group
HVPG-guided therapy
 Procedure: HVPG-guided therapy

Patients with an HVPG over 20mmHg will be suggested to receive transjugular intrahepatic portocaval shunt (TIPS) or surgical shunt operation.

Patients with an HVPG between 16 and 20mmHg can choose either endoscopic treatment or TIPS according their willingness and indication.

Patients with an HVPG below 16mmHg will be treated by endoscopy plus Carvedilol, until endoscopic treatment fails.


Drug: Carvedilol
Patients in HVPG group with HVPG below 16mmHg and all patients in non-HVPG group will take Carvedilol 12.5mg/d if they have no contraindications.
non-HVPG group
routine therapy
 Other: routine therapy
Patients start treatment without HVPG measurement and receive endoscopic therapy plus Carvedilol.

Drug: Carvedilol
Patients in HVPG group with HVPG below 16mmHg and all patients in non-HVPG group will take Carvedilol 12.5mg/d if they have no contraindications.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Mortality rate [ Time Frame: through study completion, an average of 1 year ]
    The investigators observe the mortality events in both groups during the study


Secondary Outcome Measures :
  1. Rebleeding rate [ Time Frame: through study completion, an average of 1 year ]
    The investigators observe the rebleeding events in both groups during the study

  2. Adverse Events [ Time Frame: through study completion, an average of 1 year ]
    The investigators observe any severe adverse events caused by HVPG measurement, endoscopic procedures,use of Carvedilol, surgical operations or TIPS

  3. Total cost [ Time Frame: through study completion, an average of 1 year ]
    The investigators calculate the total cost of treatment of each patient during the study
