BackgroundIn the last 2 decades the development of high-resolution manometry (HRM) has changed and revolutionized the diagnostic assessment of patients complain foregut symptoms. The role of HRM before and after antireflux procedure remains unclear, especially in surgical practice, where a clear understanding of esophageal physiology and hiatus anatomy is essential for optimal outcome of antireflux surgery (ARS). Surgeons and gastroenterologists (GIs) agree that assessing patients following antireflux procedures can be challenging. Although endoscopy and barium-swallow can reveal anatomic abnormalities, physiological information on HRM allowing insight into the cause of eventually recurrent symptoms could be key to clinical decision-making.MethodsA multidisciplinary international working group (14 surgeons and 15 GIs) collaborated to develop consensus on the role of HRM pre-ARS and post-ARS, and to develop a postoperative classification to interpret HRM findings. The method utilized was detailed literature review to develop statements, and the RAND/University of California, Los Angeles Appropriateness Methodology (RAM) to assess agreement with the statements. Only statements with an approval rate >80% or a final ranking with a median score of 7 were accepted in the consensus. The working groups evaluated the role of HRM before ARS and the role of HRM following ARS.ConclusionsThis international initiative developed by surgeons and GIs together, summarizes the state of our knowledge of the use of HRM pre-ARS and post-ARS. The Padova Classification was developed to facilitate the interpretation of HRM studies of patients underwent ARS.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
