    • Abstract:
      Gastroparesis often presents a challenge to the practicing gastroenterologist. Postprandial symptoms with nausea and vomiting may not only lead to nutritional and metabolic consequences, but also significant disruption of social activities that often center around food. The treatment options that affect gastric function are limited and often disappointing. The female predominance, the mostly idiopathic and idiosyncratic nature of the illness, often with some common psychiatric co-morbidity, parallels other functional disorders of the gastrointestinal tract. These parallels have provided the rationale for studies investigating alternative diagnostic features of the gastric emptying test as employed in the clinical setting. Hence, not only the regular cut-offs of 60% or 10% gastric retention of a meal at 2 and 4 h, but also a new concept, the intragastric meal distribution at time 0 (IMD 0 ) is now introduced as a plausible diagnostic feature that should be more aligned with the patients' symptoms as they appear in close connection with the meal. Impaired gastric accommodation with absence of fundic relaxation followed by dumping of the meal into antrum is suggested to be diagnostic for functional dyspepsia and gastroparesis. The diagnostic cut-off is considered when more than 57% of the meal is distributed to the distal part of the stomach immediately on food intake. This new diagnostic feature of the gastric emptying profile lend support to better understanding of the patients' symptoms and provides a new basis for pharmacological treatment options in gastroparesis that may provide an improved quality of life in affected individuals.
