Gastroparesis causes gastric emptying disorders in patients with chronic diabetes mellitus and it results from reduced smooth muscle contractility secondary to autonomic dysfunction. Today there has been little objective evidence of improvement in gastric emptying following correction of both uremia and diabetes by combined kidney-pancreas transplantation. We used gastrointestinal symptom scores, solid gastric emptying tests and electrogastrography to evaluate the effect of combined kidney-pancreas transplantation on gastric emptying in 8 uremic diabetic patients. The mean age of the patients was 40 years (range: 30-51 years) and the mean duration of diabetes was 24 years (range: 16-30 years). The patients had been on dialysis up to 24 months. The pretransplant A1 mean was 6.5 before improving to 4.3 after transplantation. All patients were receiving exogenous insulin. Our study data indicate that uremic diabetics have a high prevalence of symptomatic gastrointestinal dysfunction including abnormalities of gastric emptying and gastric electrical activity. Following transplantation, the gastrointestinal symptomatology improved significantly. Significant improvement in the rate of gastric emptying also correlated with improvement in the symptom complex. Gastric electrical activity also improved during the follow-up period.
