Imaging of Nonneoplastic Esophageal Pathologies

The esophagus is an organ which consists of a fibromuscular tube which enables the passage of food. This transmission is aided by peristaltic contractions, from the pharynx to the stomach, where the process of digestion reaches the acme. Efficient transport through the esophagus requires the organ either to be patent and well canalized or to have adequate motility. This consists of coordinating sequential contraction that mobilizes the bolus from above and clears acid and bile reflux from below. Dysfunction of this integrated muscular motion reduces progression of bolus and causes a distressing sense of dysphagia, chest pain, and regurgitation, or leads to other severe conditions (i.e., ab ingestis pneumonia).
