Figure 4From: Bioelectronics as a Possible Therapeutic Modality Targeting Sphincteric Dysfunction in Gastrointestinal DisordersChanges in mucosal cross sectional area at gastroesophageal junction during swallowing. This graph shows the changes in the cross sectional area of the mucosa during swallowing in non-GERD subjects and in patients with GERD. The cross-sectional areas were measured by using endoluminal ultrasound placed in the gastroesophageal junction during swallowing. The x axis represents the time from the initiation of swallow, and the y axis represents the cross-sectional areas of the mucosa relative to baseline cross-sectional area at the beginning of swallow. The graph shows that there is less change in the cross-sectional area of the gastric mucosa in GERD patients when compared with non-GERD subjects.Back to article page
