改良微血管及表面结构分型对早期胃癌诊断的临床意义

目的 探讨改良的微血管及表面结构分型(RVS)对诊断早期胃癌的临床意义。方法 回顾性分析住院且符合纳入标准的早期胃癌（EGC）及癌前病变患者60例，男性46例（76.67%），女性14例(22.33%)，平均年龄(61.03±9.87)岁, 共计病灶63处。观察符合纳入标准患者的年龄、性别、病变部位、内镜下形态分型、放大结合窄带成像内镜下微结构和微血管形态和内镜下诊断结果及病理诊断结果。结果 病理诊断胃部肿瘤性病变内镜下最常见的形态是Ⅱ型，最常见的部位为贲门和胃窦。微血管及表面结构分型（VS分型）、RVS分型均对EGC有很高的诊断价值。结论 放大结合窄带成像（ME NBI）及其镜下RVS分型有助于胃肿瘤性病变与非肿瘤性病变的鉴别，且对 EGC有很高的诊断价值。

Clinical significance of reform vessel plus surface classification in diagnosis of early gastric cancer

Objective To explore the clinical significance of reform vessel plus surface classification(RVS) in the diagnosis of early gastric cancer(EGC). Methods Totally 60 cases of EGC and precancerous lesions were retrospectively analyzed, with 46 males (76.67%) and 14 females (22.33%). The average age of patients was (61.03±9.87) years old, and their total lesions were 63. The relationship among patients' age, gender, lesion location, and endoscopic morphological classification of lesions were observed and analyzed. Results The most common endoscopic appearance was type Ⅱ form. And the most common sites of the lesions were cardia and antrum of the stomach. Both vessel plus surface classification(VS) and RVS had high diagnostic value for EGC diagnosis. Conclusion Magnifying endoscopy with narrow band imaging(ME NBI) and RVS classification can help identify gastric neoplasms and non neoplastic lesions, and they also have high diagnostic value for EGC.
