There are two different kinds of postoperative follow\u2010up: prophylactic or on\u2010demand endoscopic program of varices eradication. This program implies risks and costs and only proves necessary in 6\u201329% of cases. This study was designed to assess portal vein Doppler ultrasound data in these patients, and to verify correlations with progression in the number and size of varices, as well as the appearance of red spots and rebleeding during the postoperative period after EGDS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data on portal vein Doppler ultrasound from 146 patients with schistosomal portal hypertension and previous history of upper digestive bleeding due to esophagogastric varices rupture was analyzed. All subjects underwent EGDS and were analyzed before and after the procedure and compared postoperatively at four time points: 1 year, 2 years, up to 5 years, and up to 10 years. The following portal hemodynamic parameters were analyzed: diameter and mean blood flow velocity. Variceal size and number, presence of red spots, and rebleeding were all determined by endoscopic examination.
