Effects of Somatostatin on Post-endoscopic Portal Hemodynamic in Cirrhotic Patients With Esophageal Gastric Varices

August 31, 2011 updated by: Yunsheng Yang

Investigator Sponsored Study of Effects of Somatostatin on Post-endoscopic Portal Hemodynamic in Cirrhotic Patients With Esophageal Gastric Varices

The main complications of cirrhosis are ascites, esophageal varices and hepatic encephalopathy. About 30% to 70% patients with cirrhosis occur esophageal varices, and the most common complication is ascites. Somatostatin is used to treat esophageal for a long time, otherwise it could aslo prevent ascites. In the study, the investigators explore the effects of somatostatin on post-endoscopic portal hemodynamic in cirrhotic patients with esophageal gastric varices.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

126 patients will be enrolled in the study, 63 subjects will be randomized into the group A and the other will be into the group B.

Group A: endoscopic therapy and somatostatin treatment. Group B: endoscopic therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Portal vein blood flow volume
Time Frame: change from baseline in portal vein blood flow volume after 7 days treatment

Note:

  1. Portal vein blood flow volume will be measured by doppler ultrasound device.
  2. Values are the mean of three consecutive measurements.
  3. Frequency: PVF will be measured on baseline, day1, day 5 and day 7.
  4. All doppler studies will be carried out by a single experienced examiner who will be blinded to patient allocation.
change from baseline in portal vein blood flow volume after 7 days treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Portal vein diameter (PVD mm)
Time Frame: change from baseline in PDV after 7 days treatment
Portal vein diameter will be measured by doppler ultrasound device.
change from baseline in PDV after 7 days treatment
Mean portal vein blood velocity (PVV cm/s)
