Gastric Alimetry impacts the management pathway of chronic gastroduodenal disorders

BackgroundGastric Alimetry is a new diagnostic tool using non-invasive gastric electrical mapping and symptom logging to identify patient subgroups. This study aimed to propose an initial framework for Gastric Alimetry implementation in the routine management of gastroduodenal disorders, and assess its impact on diagnosis and management. MethodsGastric Alimetry using standard tests (30-min fasted, ~480kCal meal, followed by 4-hr postprandial recording with concurrent symptom logging) was applied to patients presenting with gastroduodenal symptoms. ResultsOverall, 50 patients were evaluated with Gastric Alimetry. The test aided management decisions in 78% of patients (39/50) and aided a change in diagnosis in 40% (20/50), predominantly from a motility disorder to disorders of gut-brain interaction (DGBI). Changes in invasive nutritional support occurred in 18% (9/50). ConclusionGastric Alimetry impacted care in most patients in this first series. Further work to inform clinical utility is now a priority.
