ABSTRACT
Background:
Nocturnal gastroesophageal reflux (nGER)is associated with severe complication of gastroesophageal reflux disease (GERD),such as esophagitis,esophageal stricture and Barrett's esophagus,and has certain effect on quality of life.Aims:
To study the characteristics of nGER and its influencing factor in patients with GERD.Methods:
GERD patients with typical reflux symptoms (heartburn or/ and regurgitation)and nGER confirmed by MII-pH monitoring were included. Effects of gender,age,BMI,DBI on nGER were analyzed.Results:
In 130 patients with GERD,97 (74. 6%)had nGER. Of the 97 patients with nGER,only 18 (18. 6%)patients complained nocturnal heartburn or/ and regurgitation. During nocturnal period,female and elderly GERD patients had delayed bolus clearance time. Percentage of time with pH < 4 and acid reflux of GERD patients with BMI≥25 kg/ m2 were significantly higher than patients with normal BMI. Nocturnal acid reflux was much lower in patients with DBI≥2. 5 hours than patients with DBI < 2. 5 hours. The weakly acidic reflux could significantly decrease along with the getting longer of DBI.Conclusions:
nGER is prevalent in GERD patients,and weakly acidic reflux is the leading type,however,only a small part of patients having nocturnal reflux symptom. The female and elderly GERD patients have delayed bolus clearance time during nocturnal period. BMI≥25 kg/m2 is associated with nGER. DBI≥2. 5 hours could significantly reduce acid reflux during nocturnal period. DBI should be as long as possible for reducing weakly acidic reflux.
