Abstract:
To investigate the influence of pressures change in gastric fundus in patients with reflux esophagitis (RE) to lower esophageal sphincter (LES) and motor function of lower esophagus. With gastro esophageal manometric catheter designed by the authors,the LESP and function of lower esophagus were synchronously measured,while the pressure in the gastric fundus was continuously increased, in 13 patients with RE and 8 healthy volunteers. The results showed that LESP and lower esophagus motor function of the RE group was significantly lower than that of the healthy group when the stomach was empty or when the pressure in the gastric fundus was increased.Whereas in the RE group, LES showed continuous relaxation,and frequent and transient lower esophageal sphincter relaxation (TLESR) were observed. It suggested that RE is an upper digestive tract motor disorder disease caused by various factors,the main mechanisms underlying RE are lower basic LES pressure and lower esophagus motor function. The LES showed continuous relaxafion and frequent and transient TLESR when the stomach is inflated.
