Abstract
Objectives: It has not been established that endoscopic treatment on cirrhotic patients with esophageal varices affects their portal blood flow. To evaluate the change of portal blood flow after the endoscopic treatment, we measured the portal blood flow before and after repeated endoscopic treatment of patients with esophageal varices. Methods: 31 patients (male: female=27: 4) with liver cirrhosis and esophageal varices which were higher than grade F1 according to Sabbas method were included. Portal blood flow(cross sectional area of portal vein, mean portal flow velocity, flow volume of portal vein) was measured using color doppler ultrasonography (SD 2000® Aloka, Japan) before and after the eradication of esophageal varices by repeated endoscopic treatment. The results were then statistically compared. Results: The measured cross sectional area of the portal vein, mean portal flow velocity, and flow volume of the portal vein were 0.77 ± 0.14 cm2, 11.6 ± 2.1 cm/sec, and 756 ± 183 ml/min respectively before eradication of esophageal varices and 0.56 ± 0.12 cm2, 13.5 ± 3.21 cm/sec, and 967 ± 93 ml/min respectively after eradication of esophageal varices (p>0.05). The values did not show statistical differences. Conclusion: Endoscopic treatment on cirrhotic patients with esophageal varices did not affect their portal blood flow.
