ABSTRACT
Gastroesophageal reflux is the most common gastrointestinal disorder in the neonatal period, and the main reason
for it is the lack of development in the first months of an infant’s digestive system and it gets improved with the aging
of baby and development of the digestive system. Some studies have shown that there is a relationship between
characteristics of anatomic and esophageal reflux. This study aimed to determine the relationship between the
characteristics and frequency of reflux in infants under one year old with gastroesophageal reflux disease. This
study is a cross-sectional study that was conducted in 2015 in the hospital of martyr Beheshti. In this study, a group
of 120 children with reflux in three age groups less than one month, 1-6 months and 6-12 months were choses and
the relationship between reflux episodes with esophagus anatomic characteristics, including distal esophagus
distention, Hiss angle, internal angle and length of esophagus were examined. The data were analyzed using the
SPSS software and the relationship between the characteristics was compared with the number of reflux in three
groups. According to the results, the frequency of reflux and extent of distention of the distal esophageal, Hiss angle,
Internal Gastro esophageal angle and length of the esophagus, there was a statistically significant correlation (P
<0.001). The correlation between reflux episodes and four parameters, are respectively, 0/95, 0/97, 0/71 and -0/79/.
Also there was a direct relation between the frequency of reflux and extent of distention of the distal esophageal,
Hiss angle, Internal Gastro esophageal angle and an inverse relation with length of the esophagus. The correlation
between the frequency of reflux and esophageal characteristics in separation between all three age groups showed a
statistically significant relationship exists between anatomical esophageal characteristics and reflux frequency.
Based on the results of this study it can be concluded that there is a direct relation between the frequency of reflux
and extent of distention of the distal esophageal, Hiss angle, Internal Gastro esophageal angle and an inverse
relation with length of the esophagus. And the patient’s age does not have a significant effect on the amount of
correlation between reflux episodes and anatomical characteristic.
Keywords: infant reflux, distention of the distal esophagus, Hiss angle, internal angle, the length of the esophagus
