Patients are often referred for evaluation of a wide range of GI complaints including dysphagia, abdominal pain, bloating, nausea, constipation or diarrhoea. Many are diagnosed with 'functional' disease when endoscopy or conventional radiological studies fail to identify an anatomic cause for the patient's symptoms. In such cases nuclear medicine offers non-invasive methods for objectively demonstrating disease involving different areas of the gastrointestinal tract. Increasingly scintigraphy is playing a primary role in the evaluation of patients with suspected acute cholecystitis, active gastrointestinal bleeding, gastroparesis, and small and large bowel motility disorders. In addition, it supplements other studies when results are inconclusive in diagnosing oesophageal dysmotility, gastro-oesophageal reflux, acalculous cholecystitis, and postoperative complications of gastrointestinal surgery.

Diabetic gastroparesis is a common problem in diabetics, especially insulin-dependent diabetics. The diagnosis usually is suggested on plain radiographs and confirmed on either upper gastrointestinal barium series or radionuclide gastric emptying studies. The clinical diagnosis is not always easy and some patients may present atypically with right upper quadrant pain simulating acute cholecystitis. In these patients, hepatobiliary scintigraphy may be the initial investigation performed and may first demonstrate unsuspected gastroparesis. Therefore, it is useful for the nuclear medicine physician to be aware of this entity to ensure early diagnosis and prompt treatment. The authors report one such case of diabetic gastroparesis that was diagnosed initially on a Tc-99m hepatobiliary scan.
