초록/해제  
요약Esophageal motility disorders (EMDs) affect a significant portion of the population, yet their mechanisms and progression remain poorly understood, impeding the development of effective treatments. By establishing a comprehensive, mechanics-based understanding of esophageal functions and dysfunctions, we can advance classification and enhance diagnostic capabilities of EMDs. This thesis proposes two novel frameworks to analyze clinical observations and reveal the complex interactions within esophageal physiology. The aim of this work is to pioneer a new area of investigation in esophagology that is based on mechanophysiology. The first framework, termed the Pressure-Cross-Sectional Area (P-CSA) Analysis, is inspired by cardiovascular literature, where pressure-volume (P-V) hysteresis of the left ventricle is used to evaluate cardiac performance. Analogous to the construction of P-V loops in cardiac physiology, the P-CSA framework involves recording and plotting the pressure inside the esophagus and lumen area of the esophagus throughout an esophageal contractile cycle. By extending the principles used for the heart to esophageal physiology, the goal of this framework is to evaluate, quantify, and characterize normal and abnormal esophageal performance. The second framework addresses the underlying mechanisms of EMDs, which are neurologically mediated mechanical dysfunctions. An understanding of how neurological disorders lead to mechanical dysfunctions of the esophagus requires knowledge of the neural circuit of the enteric nervous system. Historically, this has been elusive. Through an organ-scale neuromechanical model, this framework reveals how aberrant neural circuitry influences esophageal contraction patterns, providing insights crucial for the development of targeted pharmacological interventions. This dissertation lays the foundation for a novel approach in esophagology, integrating mechanophysiological principles to develop the first mechanics-guided disease classification and diagnostic protocol for EMDs. By bridging the gap between clinical observations and mechanistic understanding, the frameworks presented in this thesis pave the way for effective, mechanically and neurologically focused diagnostic and treatment strategies.
