The evolution of oesophageal function testing and its clinical applications in the management of patients with oesophageal disorders

Abstract

The last decade has brought significant technical advances in laparoscopic surgery. In this constantly evolving technological climate, less told is the story of the evolution of diagnostic technology that improved the clinical management of patients with oesophageal disorders. The successful outcome of the laparoscopic treatment of oesophageal disorders is due to a combination of three different factors: the skills and the ability of the foregut surgeon, the high volume of referral, the expertise in the critical evaluation of the oesophageal function tests. This is an art per se, and it is rarely acknowledged in the achievement of the excellent results of surgery. Oesophageal function testing provides the clinician with information that cannot be obtained by the clinical, endoscopic, and radiological evaluation of patients. This expertise, intimately coupled with the other factors, allows the surgeon to better understand the pathophysiology of these diseases and to provide the optimal management. Therefore, it is essential to understand the evolution that this technology is currently undergoing, and how these changes are expanding the current indications for antireflux surgery by identifying additional predictors of successful outcome.
