Background: There is little information in the literature on the diagnosis of esophagogastric varices via ultrasonic microprobe (UMP). Methods: Twenty‐one patients with esophageal varices (five cases F3; 16 cases F2) were studied. First, ultrasonographic observation of the cardiac area using deaerated water through the biopsy channel (the water repletion method) was performed followed by the balloon sheath method using MH‐246R (3.2 mm in diameter; Olympus, Tokyo, Japan). Results: The vessel images of intramural gastric varices were delineated in all 21 patients with both the water repletion method and the balloon sheath method. The overall features of perigastric collateral veins were obtained in 14 of 21 patients (66.7%) using the water repletion method and in 18 of 21 patients (85.7%) with the balloon sheath method. Vessel images of communicating veins were obtained in 10 of 21 patients (47.6%) with the water repletion method and in 17 of 21 patients (81.0%) with the balloon sheath method. Conclusion: We conclude that detailed evaluation of esophageal varix hemodynamics in the cardia is most successfully accomplished by using the balloon sheath method of UMP in conjunction with the water repletion method.
