Evaluating the Additional Value of Endoscopic Ultrasonography for Depth Assessment of Esophagogastric Junction Adenocarcinoma.

ABSTRACT:

Objectives

Endoscopic ultrasonography (EUS) is sometimes used to assess the depth of invasion in esophagogastric junction adenocarcinoma (EGJA); however, its diagnostic performance in EGJA remains unclear. This study aimed to evaluate the additional value of EUS to conventional endoscopy (CE) in assessing invasion depth.

Methods

In this single-institution retrospective study, we compared the diagnostic performance of CE alone with that of CE + EUS for preoperative depth assessment of early-stage EGJA. In addition, we examined the clinicopathologic features associated with incorrect depth assessment.

Results

The study included 93 cases of early-stage EGJA. Comparing the diagnostic performance for diagnosing submucosal cancer (CE vs. CE + EUS), CE + EUS had a significan
