Core Tip
Core tip: Endoscopic ultrasound (EUS) is the best option for staging early esophageal squamous cell carcinoma (ESCC). However, the accuracy of EUS for staging ESCC is not good and diverse. There is no other report about sub-staging T1 disease as T1a or T1b by EUS for ESCC. This study indicated that accuracy demonstrated by EUS for sub-staging T1a and T1b ESCC was only about 70%. Therefore, the technique of EUS requires further refinement to enhance its diagnostic accuracy for staging early ESCC. The results in this study indicated that EUS can stage and sub-stage early ESC pre-operatively whereas this modality need to be improved.
