Abstract
Aim: The Ultrasound Meal Accommodation Test (UMAT) is a clinical test used to assess gastric accommodation, gastric emptying, and visceral sensitivity. It has been used as a clinical tool at Haukeland University Hospital, Bergen for more than 20 years.
Material and methods: Five-hundred and nine patients were retrospectively evaluated, 71% females, and 51% were referred from other hospitals or specialists. The aim was to explore the usefulness of UMAT in patients with suspected functional GI disorders (FGID).
Results: One hundred and sixty patients were diagnosed with functional dyspepsia (FD), and 154 patients were diagnosed with irritable bowel syndrome (IBS). The overlap between IBS and FD was 41%. In 36% of FD patients, ultrasound assessment showed impaired gastric accommodation. Of 262 patients filling out all required fields for the FD diagnosis (ROMA II and III), 198 (74%) met the criteria for FD, but only 91 (34%) were later diagnosed with FD by an experienced clinician.
Conclusions: By combining ultrasonography, the symptom response to a standardized meal, and psychological assessment, the UMAT is useful in diagnosis and management of patients with FGID.
