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

Table 3 Comparison of high-frequency intraluminal ultrasound and esophagogastroduodenoscopy for variceal rebleeding

Endoscopic modality		GOV1, n = 17 (100%)
		Rebleeding (+), n = 6 (35%)	Rebleeding (–), n = 11 (65%)	P value
HFIUS	≥ CSA cutoff value1	5 (29)	2 (12)	0.02
	< CSA cutoff value1	1 (6)	9 (53)
EGD	Grade 1 with RCS	2 (12)	2 (12)	0.58
	Grade 0 or 1 without RCS	4 (24)	9 (53)

¹The cutoff value for the largest cross-sectional area was 17.2 mm². With these cutoff values, the sensitivity and specificity were 83% and 82%, respectively, for post-endoscopic variceal ligation type 1 gastric varices bleeding. The receiver operating characteristic curve had an area below the curve of 0.83 ± 0.10, which was statistically significant (P = 0.03).
