GERD: A New Understanding of Pathology, Pathophysiology, and Treatment transforms the assessment of gastroesophageal reflux disease (GERD) from its present state, which is largely dependent on clinical definition and management, to a more objective scientific basis that depends on pathologic assessment. Sequential chapters in this single-author book describe the fetal development of the esophagus, the normal adult state, and the way exposure to gastric juice causes epithelial and lower esophageal sphincter damage at a cellular level. It allows recognition of the pathologic manifestations of lower esophageal sphincter damage and develops new histopathologic criteria for quantitating such damage. This understanding provides new pathologic criteria for definition and diagnosis of GERD from its earliest cellular stage. Algorithms based on measurement of sphincter damage can identify, even before the onset of clinical GERD, persons who will never develop GERD during life, those who develop GERD but remain with mild and easily controlled disease, and those who will progress to severe GERD with failure to control symptoms, Barrett esophagus and adenocarcinoma. Aggressive early intervention in the last group with the objective of preventing disease progression to its end points of uncontrolled symptoms and adenocarcinoma becomes feasible.

Key Features

  • Provides a new method of assessment of GERD that has never previously been presented, creating a pathway to control
  • Describes a new pathologic test based on standard histology that can define lower esophageal sphincter damage
  • Sequential chapters outline the way GERD progresses from the perspective of the amount of damage to the lower esophageal sphincter
  • Provides new avenues of clinical research and technologic innovations in pathology and treatment aimed at preventing esophageal adenocarcinoma

About the Author

Parakrama Chandrasoma

Parakrama Chandrasoma

Dr. Parakrama Chandrasoma was born in Sri Lanka and received his medical education and initial pathology training in the Medical School of the University of Sri Lanka. He has postgraduate degrees in internal medicine, including the M.D. (Sri Lanka) and Membership of the Royal College of Physicians (UK). He immigrated to the United States in 1978. Upon completing his pathology residency, he assumed duties as Chief of Surgical Pathology at the Los Angeles County + University of Southern California Medical Center He has held this position since. After an initial interest in neuropathology, Dr. Chandrasoma joined Dr. Tom DeMeester’s Foregut Surgery team as pathologist in 1991. This led to a productive study of gastroesophageal reflux disease spanning 16 years and resulting in the development of numerous original concepts relating to the pathogenesis of gastroesophageal reflux disease. Dr. Chandrasoma has written over 140 peer reviewed papers and 6 previous pathology textbooks, including a general text on Gastrointestinal Pathology and a text on Gastroesophageal Reflux Disease, and is a Professor of Pathology at the Keck School of Medicine at the University of Southern California. He is married with three children and lives in Pasadena, California.
