This medical book offers an innovative and profound analysis of the immuno-mediated pathogenesis underlying neuromotility disorders such as esophageal achalasia, gastroparesis, and chronic intestinal pseudo-obstruction. Through meticulous research, Dr. Alessio Rosario Marte exposes how mast cell dysregulation leads to atypical manifestations—ranging from nonspecific gastrointestinal dysfunction to more insidious, severe symptoms—long misinterpreted in the field. By shedding light on the interaction between immune cells and gastrointestinal physiology, the book pioneers a critical rethinking of both pathogenesis and targeted therapies, positioning these disorders within an immunological framework previously unrecognized.
