Abstract
Purpose of the study
Endoscopy Normal Reflux Disease (ENRD) is a common presentation of
reflux disease. These patients are symptomatic but do not have abnormal
endoscopy findings. They may have pathological intraesophageal reflux.
Lifestyle modifications are the mainstay of management of these patients.
Posture plays an important role in their management. It was felt that exact
quantification of reflux pattern with different postures in ENRD cases
should be studied to include it as a part of management of these cases.
Basic Procedures
Fifteen male patients were studied. 24 h ambulatory pH metry was done
for all patients. Half an hour recording was studied for various postures:
supine, supine with 30° head end elevated, upright, right and left lateral
recumbent position. The data of pH metry for half an hour of each of these
postures was studied.
Results and Interpretation
All fifteen patients were ENRD cases and were upright refluxers. None
of them had an abnormal supine reflux pattern. The percentage time of
reflux and the reflux episode duration was significantly low in supine
(P<0.05) and supine with 30° head end elevated (P<0.005).
Conclusion
In our study of 15 upright refluxers, supine with 30° head end elevated
and supine position were the postures associated with least reflux. Posture
can help reduce the reflux significantly and can be used as an effective
means in management.
