基层医院56例早期胃癌胃镜下表现的分析

目的探讨早期胃癌(EGC)普通胃镜下的表现,为提高基层医院EGC的检出率提供参考。方法回顾性分析我院确诊的早期胃癌56例患者的内镜下表现,包括发生部位、大小、分型及各型表现以及亚甲蓝着色特征。结果 56例患者中,病灶位于胃窦部22例(39.3%),胃体部18例(32.1%),胃角部10例(17.9%),贲门部6例(10.7%)。单个病灶直径为0.5~2.6 cm,平均(1.28±1.36)cm。Ⅰ型(隆起型)12例(21.4%),Ⅱ型(平坦型)36例(64.3%),其中Ⅱa型(浅表隆起型)10例(17.9%),Ⅱb型(浅表平坦型)2例(3.6%),Ⅱc型(浅表凹陷型)24例(42.9%),Ⅲ型(溃疡型)2例(3.6%)。56例患者经亚甲蓝染色后,病变黏膜呈黑色或深蓝色48例(85.7%),浅蓝色6例(10.7%),不着色2例(3.6%)。结论 EGC好发于胃窦部,以Ⅱc型为主,多数病变亚甲蓝染色呈深蓝色。

Gastroscopic manifestation of 56 patients with early gastric cancer in primary hospital

Objective To explore the gastroscopic manifestation of early gastric cancer（EGC） and provide references for improving the detection rate of EGC in the primary hospital. Methods The gastroseopic manifestation of 56 patients with EGC including the site, size,typing and other represent of every types, and dyeing by methylene blue were analyzed retrospectively. Results Among the 56 patients, there were 22 （39.3%）patients＇ lesion located in gastric antrum, 18 （32.1%） cases in gastric body, 10 （17.9%） cases in gastric angle ,and 6 （ 10.7% ） cases in cardiac part. The diameter of the lesions was 0.5 - 2.6 cm, with a average of （ 1.28 ±1.36 ） em. There were 12（21.4% ） patients with type I （protrude type） ,36 patients（64.3% ） with type Ⅱ （flat type） including 10 patients（ 17.9% ） with type Ⅱ a （ superficial protrude type） ,2 （ 3.6% ） patients with type Ⅱ b （ superficial flat type） ,24 （42.9%） patients with type Ⅱ c （ superficial concave type） , and 2 （ 3.6% ） patients with type m. The lesions of 48 （ 85.7% ） cases showed black or dark blue after methylene dyeing,6 （ 10.7% ） cases showed light blue, and 2 （3.6%） cases were not colored. Conclusion EGC is easy to generate in gastric antrum, majored in type Ⅱ c, and showed black or dark blue after methylene dyeing.
