Evaluation of transabdominal ultrasound after oral administration of an echoic cellulose-based gastric ultrasound contrast agent for gastric cancer

Table 1 Detection rates for gastric cancer and high-grade intraepithelial neoplasia using TUS-OCCA

Gastric cancer and premalignant lesions	Detection rates		Total
Gastric cancer and premalignant lesions	Group S	Group U
High grade intraepithelial neoplasia	6/6	0/4	6/10 (60 %)
Stage T1a early gastric cancer	14/14	2/10	16/24 (67 %)
Stage T1b early gastric cancer	18/18	2/8	20/26 (77 %)
Advanced gastric cancer (stage T2 ~ T4)	146/146	82/82	228/228 (100 %)
Total	184/184 (100 %)	86/104 (83 %)	270/288 (94 %)

TUS-OCCA, transabdominal ultrasound after oral administration of an echoic cellulose-based contrast agent. The difference in the detection rates between Groups S and U (100 % vs. 83 %) was significant (p < 0.05, Fisher’s exact test)
