目的探讨24 h食管持续pH监测对诊断胃食管反流的临床意义。方法用自制佩带式24 h食管pH监测系统,对82有例胃食管反流症状的患者和40例无上消化道症状的正常人进行了常态下24 h食管pH监测。结果国人24h食管pH监测指标的正常阈值:食管pH<4次数<22.11;pH<4总时间的%<1.89;站立位pH<4时间%<2.42;卧位pH<4时间%<1.0;pH<4大于5 min以上次数0次;综合指标总计分<15。24 h食管持续pH监测各项参数GERD组明显高于正常组差别显著(P<0.01)。结论 24 h食管pH监测对诊断GER有重要意义,综合指标总计分的高低与反流症状轻重有关,是判断生理性和病理性反流的重要指标。
Objective To investigate the clinical significance of 24 h continuous esophageal pH monitoring in the diagnosis of gastroesophageal reflux disease. Methods A homemade 24-h esophageal pH monitoring system was used to monitor esophageal pH at 24 h in 82 patients with gastroesophageal reflux symptoms and 40 normal controls without upper gastrointestinal symptoms. Results The normal thresholds for 24-hour esophageal pH monitoring in Chinese people were as follows: esophageal pH <4 times <22.11; pH <4% of total time <1.89; standing pH <4 time% <2.42; <4 more than 5 min 0 times; comprehensive indicators total score <15.24 h esophageal continuous pH monitoring parameters GERD group was significantly higher than the normal group significant difference (P <0.01). Conclusion The 24-h esophageal pH monitoring is of great significance for the diagnosis of GER. The total score of the comprehensive indexes is related to the severity of reflux symptoms and is an important index for judging the physiological and pathological reflux.
