title: The ultrasound meal accommodation test in 509 patients with functional gastrointestinal disorders.
abstract: OBJECTIVE
  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.
  
  
  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.
