The capacity of endoscopic ultrasound (EUS) to distinguish the different wall layers of the gastrointestinal (GI) tract and the possibility to obtain samples of suspicious lesions or lymph nodes by means of EUS-guided fine-needle aspiration (EUS-FNA), make EUS an ideal staging modality for GI cancers. After an endoscopic and histological diagnosis of gastric cancer (GC), an accurate preoperative evaluation is essential to choose the correct management decision, because for this malignancy various and radically different stage-oriented therapies can be performed. Even if EUS is inserted in the last guidelines for the management of GC as an essential pretherapeutic staging modality, in the literature the reported accuracy, the imaging features and the performances of the technique are variable. In this review, we synthesize the current status and the imaging findings of EUS when describing and staging GC, with a particular attention to the early GC that represents till today a diagnostic and therapeutic challenge. Currently, the EUS study is mandatory for the preoperative staging, to assess with a good accuracy the tumor depth of wall invasion, the presence of suspicious lymph-nodes and of ascites (predictive of peritoneal involvement). The main limitations for a correct EUS staging remain some features of the lesion or its localization, so more attention should be paid when these characteristics are present.
