Key Points

This research aims to evaluate the effectiveness of diagnosing subserosa invasion in malignant gallbladder tumors.
Evaluated irregular lateral high-echoic layer (LHEL) as an indication of SS invasion.
Analyzed the presence of deep hypoechoic area combined with LHEL.
Used endoscopic ultrasonography for diagnosis.
Identified LHEL as a significant echoic indication of SS invasion alongside deep hypoechoic area.
Suggests a potential improvement in SS invasion diagnosis methods.

Abstract

The reader noted that a deep hypoechoic area is the main echoic indication of subserosa (SS) invasion of malignant gallbladder tumors. In this study, we evaluated an irregular lateral high-echoic layer (LHEL) as the main indication of SS invasion. If the presence of a deep hypoechoic area combined with an irregular LHEL is considered, the diagnosis of SS invasion may be improved.
