This study aimed to examine the clinical features and endoscope imagery of gastroesophageal reflux
disease (GERD) in the elderly. We conducted a cross - sectional study of 96 elderly patients from Bach Mai
hospital’s gastroscopy unit. 58.3% of the patients were female. The mean age was 73.12 + 8.22, with a
range from 60 - 92 years old. The majority of participants suffered from GERD for less than one year (50%).
The most common clinical symptoms were burning (67.7%), epigastric pain (63.5%) and heartburn (63.5%).
Other symptoms included persistent cough (30.2%) and dysphasia (25.0%). The most common risk factors
for GERD were being overweight or obese (40.6%) and alcohol or beer consumption (21.9%). Most of the
patients were found to have pharyngitis grade A (49.9%) or pharyngitis grade B (34.4%). Patients commonly
had accompanying gastritis symptoms. Additionally, the proportion of patients with Barrett’s esophagus was
high at 30.3%. In conclusion, popular signs of GERD in this elderly patient population included burning, epi-
gastric pain and heartburn. Given the high percentage of patients found to have Barrett's esophagus, there
may be a need for continued monitoring of these patients with endoscopy to prevent future complications.

of GERD in the elderly include esophageal
tumors, being male, smoking, advanced age,
and obesity [5]. GERD is a common gastroin-
testinal disorder in the elderly, considerably
affecting patients’ quality of life [6]. Accessing,
close monitoring, and early recognition of
GERD in the elderly are essential to treat the
disease and prevent complications. The aims
of this study were to review the clinical charac-
teristics and endoscopic imaging findings of
GERD in elderly patients in Vietnam.

The rate of Barrett’s esophagus was relatively high (30.3%). Bleeding was rare (1.01%). No
cases of esophageal cancer were detected.
IV. DISCUSSION
Previous research has revealed two com-
mon and typical symptoms of GERD: burning
behind the sternum and heartburn [5; 8]. En-
doscopy, biopsy, 24 hour PH calculation, and
X-ray imaging of the esophagus with contrast
are not common parts of the investigation of
GERD. Therefore, it is difficult to document
accurately disease rates in the community.
Rates of GERD in high income countries were
reported to be between 10 - 48% [15]. In Xian
(China), the proportion of individuals experi-
encing burning behind the sternum at least
once a day was found to be 1.66%, at least
once a week was 4.06% and at least once a
month was 10.98% [16]. In a study by Dent et
al., where residents in Minnesota, USA were
randomly interviewed via telephone, 19.8-
20% of respondents were found to have burn-
ing behind the sternum and/or heartburn every
week. 17.4 - 17.8% of these respondents
reported a single burning sensation occurring
every week; rates of daily acid reflux were 6.3
– 6.6 % [9].
GERD include alcohol consumption, smoking,
being overweight or obese, and several medi-
cations (including calcium channel blockers
and NSAIDs). In our study, 21.9% of patients
with GERD reported a history of alcohol use,
14.6 % reported a history of smoking, 40.6%
of patients reported being overweight or
obese, 18.8% used calcium channel blockers,
and 10.4% used NSAIDs. The rate of alcohol
and tobacco use was lower than that found in
other studies, possibly due to the characteris-
tics of our patient population. Our patients
were 60 years old and above and the majority
were female.
Results of stomach and esophageal endo-
scopy showed the following levels of esophag-
eal injuries, based on the Los Angeles classifi-
cation system: pharyngitis grade A (49.0%),
pharyngitis grade B (34.4%), pharyngitis grade
C (13.5%) and pharyngitis grade D (3.1%).
These results highlighted the fact that in our
patients, GERD developed slowly and gradu-
ally. We found considerable rates of gastroe-
sophageal reflux among the older patients in
our sample, which is consistent with a previ-
ous study by Huang et al [10]. It is also note-
worthy that 30.3% of the patients in our study
had Barrett’s esophagus, one patient was
found to have an esophageal ulcer and 1.04%
of patients had esophageal bleeding. No
patient was found to have esophageal
cancer. The rate of Barrett’s esophagus
among our respondents was relatively high,
which may suggest an association between
the age of a patient with GERD and the risk of
Among the elderly patients in our study,
common clinical symptoms of GERD included
epigastric pain (63.5%), burning (67.7%) and
heartburn (63.5%). Digestive symptoms were
not frequent. Extra - esophageal symptoms
included persistent cough (30.2%), chronic
sore throat (27,1) and dysphasia (25.0%). The
proportion of patients reporting odynophagia
and difficulty breathing were lower than that
found in previous studies, but the rate of eso-
phageal injuries was still high [4; 6; 8; 9]. Pre-
vious research showed that risk factors for

development of Barrett's esophagus. Because
the risk of esophageal cancer is 30 - 120 times
higher in those who experience Barrett’s
esophagus than in those without Barrett’s
esophagus, an endoscopic monitoring pro-
gram is needed for elderly patients with GERD
[4; 11]. Our results showed that 96.9% of
GERD patients had accompanying gastritis,
3% experienced stomach ulcers, 14% had
duodenal ulcers, and 5.2 % experienced duo-
denitis, which are rates comparable with those
found in past studies [12; 13].

V. CONCLUSION
Gastroesophageal reflux disease was
found to occur more frequently in elder
females than in elderly males. The most com-
mon symptoms were burning (67.7%), epigas-
tric pain (63.3%) and heartburn (63.0%). The
most common esophageal injuries were
pharyngitis grade A (49.0%) and grade B
(344%), frequently accompanied by gastritis
(96.9%). 30.3% of patients experienced Bar-
rett’s esophagus, though it was not closely
monitored.
