“…T ransabdominal sonography is a noninvasive, simple, quick, and safe technique to visualize the gastroesophageal junction [1][2][3][4][5] and is useful for studying gastroesophageal reflux, esophagitis, hiatal relaxation, esophageal varices, and esophageal involvement by malignant tumors. 3,4,[6][7][8] An understanding of normal sonographic anatomy is fundamental to the study of gastroesophageal abnormalities.…”

“…[32] In our study, abdominal esophagus length was measured in children having GERD to confirm the results of other studies suggesting that with an inadequate length of the abdominal esophagus, the prevalence of GERD is high. [35–37] When discriminating between mild, moderate, and severe GERD on the basis of the number of refluxes per 10 min, we found that only neonates with severe reflux had a significantly shorter abdominal esophagus compared with neonates with mild reflux. Such differences related to GERD severity were found either between other category groups of GER severity in this age group or between any pair comparison in older infants.…”

Background/Aim:This study was conducted to provide sonographic measurements of the abdominal esophagus length in neonates and infants with and without gastroesophageal reflux disease (GERD) and to investigate its diagnostic value. GERD severity was also evaluated and correlated with esophageal length. It is a prospective case-control study.Materials and Methods:This prospective case-control study comprised 235 neonates and infants (120 without reflux and 115 with reflux). There were 40 children without reflux in each of three age categories: less than 1 month, 1–6 months, and 6–12 months. Of the children with reflux, 40 were less than 1 month old; 37, 1–6 months; and 38, 6–12 months. The abdominal esophagus was measured from its entrance into the diaphragm to the base of gastric folds in fed infants. GERD was sonographically diagnosed and confirmed by a barium meal. The number of refluxes during a 10-min period were recorded.Results:Neonates and infants with reflux had a significantly shorter abdominal esophagus than subjects without reflux: the mean difference in neonates, 4.65 mm; 1–6 months, 4.57 mm; 6–12 months, 3.61 mm.Conclusions:Children with severe reflux had a shorter esophagus compared with those with mild and moderate reflux only in the neonate group. Therefore, thinking of GERD and carefully looking for its symptoms is necessary to avoid unnecessary utilization of healthcare resources in children with severe reflux.

“…The gastrointestinal tract is routinely observed by US, because gastric disorders (cancer, submucosal lesions, peptic ulcer) can be clearly visualized on ultrasound screening, when condition of patients is the left lateral decubitus (LLD) position [2]. Moreover, the gastroesophageal junction and gastric antrum are easily demonstrated on US with the patient in the supine position [5][6][7][8]. However, the lesser curvature of the stomach (LCS) is often difficult to observe in the supine position; especially in obese patients, it is difficult to obtain imaging of the LCS.…”

The aim of this study was to evaluate the usefulness of an imaging technique that takes into account the effect of posture change on the stomach in transabdominal ultrasonography (US). A total of 240 adult patients (healthy subjects) underwent gastric US. In all subjects, the lesser curvature of the stomach (LCS) and left liver were measured in two different positions [left lateral decubitus (LLD) and supine]. The maximal length of the LCS was defined as the measured range between the cardial orifice and the left liver tip. The anteroposterior length (L1) and maximal longitudinal length (L2) of the left liver were determined on epigastric longitudinal scans. The mean LCS in the supine and LLD positions was 90.2 +/- 34.7 and 124.4 +/- 44.4 mm, respectively. The mean L1 in the supine and LLD positions was 54.0 +/- 12.7 and 65.6 +/- 14.4 mm, respectively. The mean L2 in the supine and LLD positions was 84.3 +/- 18.5 and 107.0 +/- 25.8 mm, respectively. The results for the measured LCS, L1, and L2 differed significantly between the supine and LLD positions (P < 0.05). This study demonstrated that the LCS could be clearly visualized on longitudinal scanning in the LLD position. Therefore, this position may potentially be more useful for gastric US, even in view of the limitations of this approach.
