Gastric subepithelial lesions (SELs) are often detected incidentally during upper gastrointestinal endoscopy. Although most SELs are benign, endoscopic differentiation between malignant and benign lesions is important. Endoscopy is useful to determine the location, color, consistency, mobility, surface characteristics, and approximate size of gastric SELs. EUS can distinguish between intraluminal lesions and extraluminal compression and confirm the exact size, layer of origin, echogenicity, and homogeneity of SELs. Accurate understanding of the endoscopic and EUS features of gastric SELs is useful to effectively design an appropriate management plan and thereby minimize the rate of unnecessary surveillance or overtreatment.
胃黏膜下病变（SELs）常在进行上消化道内镜检查时被偶然发现。尽管大多数SELs是良性的，但区分恶性和良性病变在内镜检查中很重要。内镜检查有助于确定胃SELs的位置、颜色、质地、活动度、表面特征以及大致大小。超声内镜（EUS）可以区分腔内病变和腔外压迫，并确认SELs的确切大小、起源层次、回声性和均匀性。准确了解胃SELs的内镜和EUS特征有助于有效制定合适的管理方案，从而将不必要的监测或过度治疗率降至最低。
