摘要
目的 :探讨正常儿与胃食管反流 (GER)患儿的胃肌电活动特点 ,认识小儿GER的病因及病理生理特征 ,为治疗提供客观依据和指导。方法 :对 2 0例正常儿及 2 0例GER小儿进行胃电图监测 ,记录主功率 (DP)、主频率等指标。结果 :GER患儿主频值明显减低 ,胃电节律紊乱 ,以胃动过速为主。GER患儿大多存在胃动力障碍。结论 :胃动力障碍 ,胃 -幽门窦 -十二指肠蠕动不协调是造成GER的主要因素。
Objective: Our aim was to investigate the behavior of gastromyoelectric in patients with GER and healthy children, and the characteristics of pathogenesis and pathophysiology of GER children. Methods: In 20 healty and 20 children with GER, we recorded the correlated indices including dominant power(DP), dominant frequency (DF) of electrogastrogram. Results: Compared with healthy children, DF in GER children was obviously decreased. Gastric electrical rhythm in GER children was disordered, and mainly displayed as tachygastria. Most of GER children suffered from obstacle of gastric power. Conclusion: Obstacle of gastric power and incoordinated peristalsis of stomach-pylorus-duodenum are main causes of GER. Electrogastrogram can objectively reflect the variation of gastricmyoelectric action and gastric power, and can provide guide for diagnosis and therapy for GER.
