Analysis on 462 Cases of Erosive Gastritis

目的探讨糜烂性胃炎(EG)在内镜下的形态、分布及预后.方法对1997年1月～2003年12月经内镜确诊的462例糜烂性胃炎进行分析.结果462例中,男性336例,女性126例,男女之比2.67:1.隆起糜烂型185例,占40.04%;平坦糜烂型277例,占59.96%.胃窦部363例,占总数的78.57%;其中隆起糜烂型173例,占47.66%;平坦糜烂型190例,占52.34%,两型之间差异无显著性(P＞0.05).胃高位99例,占总数的21.43%;其中隆起糜烂型12例,占12.12%;平坦糜烂型87例,占87.88%;胃窦部隆起糜烂型占47.66%(173/363),胃高位隆起糜烂型占12.12%(12/99);隆起糜烂型和平坦糜烂型HP感染率分别为83.78%和27.08%,差异有非常显著性(χ2=142.68,P＜0.01).结论胃窦部与胃高位糜烂性胃炎的发病率均以男性为主,其中隆起糜烂型好发于胃窦部,而胃高位以平坦糜烂型为主.

[Objective] To study the shape, distribution and prognosis of erosive gastritis （EG） under the endoscope. [Methods] Analysis was done on 462 cases of erosive gastritis diagnosed by endoscope since Jan. 1997 to Dec. 2003. [Results] Among the 462 cases, 336 cases were males and 126 cases were females with a ratio of 2.67 ： 1 ; 185 cases were swell erosive type （ 40.04% ） ; 277 cases were fiat erosive type （59.96% ） ; 363 cases were located at the antrum of the stomach （78.57% ）, among which 47.66% were swell erosive type （173 cases）, 52.34% were fiat erosive type. No significant difference was found between the two types （ P 〈 0.05） . 99 cases {21.43% ） were located at high part of stomach, among which 12 cases {12.12% ） were swell and erosive type and 87 cases （87.88% ） were fiat and erosive type. There were significant difference between the two types （ P 〈 0.01 ） . 47.66% （ 173/363 ） of the swell erosive type were located at the antrum of stomach, 12.12% （ 12/99） were at high part of stomach. The difference was significant between the two parts （ P 〈 0.01 ）. [ Conclusion] Both the erosive gastritis that are located at the antrum and at high part of stomach mainly occur among males. Swell erosive type usually attacks the antrum of the stomach, while fiat erosive type usually attacks the high part of the stomach.
