本研究采用内镜测压术，检测８０例证属脾胃虚弱型和肝胃不和型的慢性胃炎患者幽门括约肌压力变化。结果，脾胃虚弱型患者幽门括约肌收缩振幅降低、收缩频率减慢，而肝胃不和型患者幽门括约肌收缩振幅增高、收缩间期延长，与正常对照组比较均具非常显著意义（Ｐ＜０．０１）。表明幽门括约肌压力参数变化可作为慢性胃炎辨证分型的胃动力学参考指标，并可指导临床治疗用药和疗效评定。
In this study, endoscopic manometry was used to detect changes in pyloric sphincter pressure in 80 patients with chronic gastritis characterized by spleen-stomach weakness and liver-stomach disharmony. As a result, the contraction amplitude of pyloric sphincter was decreased and the frequency of contraction was slowed down in patients with spleen-stomach weakness, but the contraction amplitude of pyloric sphincter was increased in patients with liver-stomach disharmony. The contractile interval was prolonged, which was significant compared with the normal control group (P <0. 01). Pyloric sphincter pressure parameters that can be used as a chronic gastritis Syndromes of gastric motility reference index, and can guide the clinical treatment of medication and efficacy evaluation.
