The Contemporary Diagnostic Approaches to Esophageal Symptomatology

Esophageal symptoms, including dysphagia, heartburn, and non-cardiac chest pain, are prevalent concerns in gastroenterology. This review examines the roles of advanced diagnostic modalities such as high-resolution manometry (HRM), pH-impedance monitoring, and EndoFLIP in understanding esophageal physiology and pathology. Here, we discuss the clinical presentations of common esophageal symptoms and explore how structural abnormalities like strictures and motility disorders, including achalasia and esophageal spasms, are assessed using these tools. The diagnostic utility of endoscopy in visualizing mucosal and structural changes is highlighted alongside emerging technologies like artificial intelligence in enhancing detection capabilities. Complementary techniques, such as barium esophagrams and reflux monitoring, provide additional functional and anatomical insights, crucial for comprehensive patient evaluation. The integration of these diagnostic approaches fosters a deeper understanding of esophageal disorders, guiding effective management strategies and improving patient outcomes. This review aimed to highlight the importance of adopting a multimodal diagnostic approach in modern gastroenterological practice.
