Abstract
Purpose of review: The gastrocolonic response (GCR), is a physiologic increase in motor activity of the colon, which usually occurs within minutes following meal ingestion. Over the years several triggers that provoke GCR were recognized including gastric dilation, caloric intake, and fat component of the meal. The response is mediated by the vagal nerve and neurohumoral mechanisms, and it can be modified by several pharmacological factors. Assessment of GCR is part of high-resolution colonic manometry studies, performed in patients with suspected colonic dysmotility. This review highlights the physiologic basis of GCR as well as its clinical and diagnostic features and implementation in variable pathological conditions and clinical practice.
Recent findings: GCR has a role in patients with constipation, diabetes, dumping syndrome, bowel hyper and hypomotility and irritable bowel syndrome. Novel sensory triggers for GCR were recently recognized. GCR is a physiological response which is evaluated during colonic manometry studies. Abnormal GCR is a marker of an underlying pathology, which can provide a potential target for treatment.
期刊介绍：
As the field of gastroenterology and hepatology rapidly evolves, the wealth of published literature can be overwhelming. The aim of the journal is to help readers stay abreast of such advances by offering authoritative, systematic reviews by leading experts. We accomplish this aim by appointing Section Editors who invite international experts to contribute review articles that highlight recent developments and important papers published in the past year. Major topics in gastroenterology are covered, including pediatric gastroenterology, neuromuscular disorders, infections, nutrition, and inflammatory bowel disease. These reviews provide clear, insightful summaries of expert perspectives relevant to clinical practice. An Editorial Board of internationally diverse members suggests topics of special interest to their country/region and ensures that topics are current and include emerging research. We also provide commentaries from well-known figures in the field.
