Comparative study for predictability of type 1 gastric variceal rebleeding after endoscopic variceal ligation: High-frequency intraluminal ultrasound study

Figure 4 Comparison of high-frequency intraluminal ultrasound estimates of largest variceal cross-sectional area between patients with or without post-endoscopic variceal ligation variceal bleeding. The mean largest variceal cross-sectional area (CSA) of type 1 gastric varices patients who experienced post-endoscopic variceal ligation (EVL) bleeding was significantly greater than that of patients who did not experience post-EVL bleeding (22.2 ± 7.7 mm² vs 11.2 ± 9.2 mm², respectively; P = 0.03). Horizontal bars represent median values, and the upper and lower ends of the bars represent quartile values. EUS: Endoscopic ultrasound.
