胃癌患者胃排空的研究

Study on Gastric Emptring in patients with Gastric Cancer

目的实时超声观察胃排空是研究胃运动功能安全、无损伤、重复性好的方法。胃癌患者可能存在胃运动功能障碍。本研究通过观察胃癌患者的胃液体排空，探讨胃癌患者的胃运动功能。材料与方法胃液体排空时间测定，通过对胃窦体积的观察，测定28例胃癌及23例正常人的胃排空时间。所用仪器为日本产ALOKA256型线阵式实时超声显像仪，探头频率3．5MHz。结果胃癌患者的胃液体排空时间为53．75±8．67min，较正常对照组的43．70±10．38min显著延迟（P＜0．05）。结论胃癌患者存在着明显的胃液体排空延迟，表明存在胃运动功能障碍。

Objective To observe gastric emptying time with ultrasound, to study the gastric motor funciton (GMF) in patients with gastric cancer (GC) and normal subjects. Materials and Methods A total of 51 subjects were examined including 23 normal subjects and 28 patients with GC. Assessed gastric emptying time (GET) based on measurements of the antrum volume by real - time ultrasound method. Ultrasound examinaton were performed with a high -resolution real-time scanncer (ALOKA 256) with a 3.5 mHZ linear array transducer. Results The GET of patients with gastric cancer was 53.75±8.67min, while the GET of the control groups was 43.75± 10. 38 min(P < 0.05).Conclusions There was singificant delay of GET in GC patients, which was resulted of GMF inpediment.
