Dr. Camilleri: There are three really important points to make. The first is that the previous guideline from ACG was published in 2013—a decade ago (Am J Gastroenterol 2013;108[1]:18-37). The second is that there still is an unmet need in terms of diagnosis and treatment. And the third is that there’s interest in the guideline for gastroparesis, with the 2013 guideline being cited over 570 times. Although the European Society of Neurogastroenterology and Motility published a consensus document more recently (United Eur Gastroenterol J 2021;9[3]:287-306), it was based on expert opinion, in contrast to the rigor of the ACG guideline based on extensive literature search and GRADE methodology. In addition, some novel diagnostic and therapeutic approaches have come to the fore over the past decade, and they needed to be summarized for clinicians and patients.
