Irritated Esophagus Leading to Acid Reflux

Description

Centered in the upper abdomen, the distal esophagus descends from the pharynx (throat) to meet the stomach at the gastroesophageal junction, where the mucosa is shown inflamed and eroded in keeping with reflux esophagitis from chronic acid exposure. Inferiorly, the gastric cardia and fundus display prominent rugae, with the liver positioned superior and to the patient’s right and the spleen superior and to the patient’s left. Posterior to the stomach, the left kidney and suprarenal (adrenal) gland sit retroperitoneally, while the proximal duodenum and early small intestine extend distally from the pyloric region. Reflux is not just a symptom label. Acid injury at the distal gullet concentrates at the lower esophageal sphincter region and diaphragmatic hiatus, where transient sphincter relaxations or a sliding hiatal hernia can expose squamous epithelium to gastric contents and drive pain, dysphagia, and nocturnal regurgitation. Persistent inflammation can progress to peptic stricture or Barrett esophagus with intestinal metaplasia, and the male demographic is overrepresented in progression to dysplasia and adenocarcinoma. The junction matters. Use this artwork to teach upper gastrointestinal anatomy and GERD pathophysiology in medical and nursing courses, to support patient education on acid reflux and esophagitis, or to illustrate discussions of endoscopic landmarks and anti-reflux surgery (for example, fundoplication) in clinical handouts and publishing. Ideal for gastroenterology, general surgery, and primary care materials. Anatomical accuracy verified by SciePro's Medical Advisory Board.
