摘要 目的探讨共聚焦内镜对早期胃癌内镜黏膜下剥离术(endoscopic submucosal dissection,ESD)治疗范围确定的可行性及准确度。方法选择经普通胃镜检查加组织活检确诊为胃癌,并经超声胃镜检查病变局限于黏膜层的患者25例。用共聚焦内镜对病灶黏膜进行多部位扫描,找到正常黏膜与癌变黏膜的分界线,并对分界线用氩离子血浆凝固术(APC)进行标记,沿APC标记界限行ESD治疗,将剥离黏膜送病理科,对病灶组织由浅至深逐层切片,对所有组织切片进行逐层观察,并检查病灶切除的完整性。结果经共聚焦内镜标记的早期胃癌黏膜切除完整,癌灶边缘有一圈少许正常黏膜组织,深层癌灶剥离完全。结论共聚焦内镜能清晰地区分癌变胃黏膜和正常黏膜结构,为早期胃癌的ESD提供有效的治疗界限,为早期胃癌的完整切除提供安全保障,避免了单纯在普通胃镜下靠经验估计的盲目性。
