目的 :探讨胃镜对胃下垂的诊断方法。方法 :常规胃镜检查 ,依据胃窦宽度、运动状态及幽门口开放度等 ,将胃窦动力状态区分为胃窦弛缓型、胃窦紧张型、返流型及正常型。同时测量门齿～幽门间距 ,并计算门齿～幽门间距 /身高比值。结果 :胃下垂患者中胃窦弛缓型占 77.5 % (31/ 40 ) ,对照组为 2 6 .7% (8/ 30 )。胃下垂患者门齿～幽门平均间距为 81.9cm ,门齿～幽门间距 /身高比值为 0 .5 19+0 .0 16 ,对照组平均间距为 74.5cm ,门齿～幽门间距 /身高比值为 0 .433± 0 .0 2 2 ,两组比值比较 ,差异非常显著 (P <0 .0 1)。结论 :胃镜对胃窦动力状态的观察及计算门齿～幽门间距 /身高比值 ,可为胃镜诊断胃下垂提供重要依据。
Objective: To explore the diagnosis of gastroscopy on gastric ptosis. Methods: According to the conventional gastroscopy, the dynamic state of gastric antrum was divided into gastric antrum relaxation, gastric antrum tension, reflux and normal type according to the width of gastric antrum, exercise status and the open degree of pylorus. Simultaneous measurement of incisors ~ pylorus spacing, and calculate the incisors ~ pylorus spacing / height ratio. Results: The gastric anastomosis accounted for 77.5% (31/40) in the patients with gastric ptosis and 26.7% (8/30) in the control group. The average distance between incisors and pylorus in patients with gastroptosis was 81.9 cm, the ratio of distance from dentition to pylorus was 0. 5 19 +0 0 16, the average distance between control group was 74.5 cm and the ratio of incisors to pylorus was 0.433 ± 0 .022, the difference between the two groups was significant (P <0.01). Conclusion: The observation of gastroscopy to the dynamic state of gastric antrum and the calculation of the ratio of the distance from the gate to the pylorus can provide an important basis for the diagnosis of gastroptosis by gastroscopy.
