[目的]探讨胃癌患者阻抗式胃动力学指标特点。[方法]采用阻抗式胃动力诊疗仪对健康成人、良性溃疡及胃癌患者进行空腹及标准餐后阻抗式胃动力检测,记录胃运动节律、平均振幅、频段能量比等指标。[结果]①胃癌与胃溃疡患者的胃动力明显异于健康成人;②胃癌与胃溃疡患者在胃运动节律、平均振幅、胃动力总评对比差异无统计学意义(P>0.05);③进展期胃癌与胃溃疡对比,差异有统计学意义,尤其是BorrmannⅡ、Ⅲ型胃癌与胃溃疡患者对比,在胃运动节律、胃动力总评两方面差异具有统计学意义(P<0.05);④胃癌患者餐前平均振幅均明显高于健康成人及胃溃疡患者(P<0.05)。[结论]与健康成人对比,胃癌患者存在明显的胃动力学异常,与胃溃疡患者对比,进展期胃癌胃动力学存在明显差异。
[Objective] To investigate the characteristics of impedance gastric motility in patients with gastric cancer. [Method] The fasting and standard postprandial gastric motility test was performed on healthy adults, benign ulcer patients and gastric cancer patients by impedance gastric power therapy instrument. The indexes of gastric motor rhythm, average amplitude and frequency energy ratio were recorded. [Results] ① The gastric motility of patients with gastric cancer and gastric ulcer was significantly different from that of healthy adults. ② There were no significant differences in gastric motor rhythm, average amplitude and total gastric motility between patients with gastric cancer and gastric ulcer (P> 0.05) Gastric cancer and gastric ulcer, the difference was statistically significant, especially Borrmann Ⅱ, Ⅲ type gastric cancer and gastric ulcer patients compared with gastric motor rhythm, total gastric motility in two aspects was statistically significant difference (P <0.05); ④ gastric cancer patients meal Before the average amplitude were significantly higher than healthy adults and patients with gastric ulcer (P <0.05). [Conclusions] Compared with healthy adults, gastric cancer patients have obvious abnormal gastric motility. Compared with patients with gastric ulcer, gastric motility in advanced gastric cancer has significant difference.
