Acute Gastric Dilatation Accompanied by Diabetes Mellitus

A 72-year-old man with diabetic triopathy was hospitalized with methicillin resistant staphylococcus aureus pneumonia. Six hours after the admission, his abdomen was fully expanded. An abdominal X-ray showed gastric dilatation. After insertion of a gastric tube to extract gastric air, his abdomen was flat and gastric dilatation improved. A positive Schellong test and decreased coefficient of RR interval in electrocardiogram variation indicated autonomic neuropathy, which may explain the reason for gastric hypomotility. Acute gastric dilatation in this patient may have occurred due to gastric hypomotility as a result of diabetic autonomic neuropathy in addition to gastric motility inhibition resulting from gastric autonomic nerve stimulation by bacterial toxin.
