Gastric emptying after intestinal resection in Crohn's disease

Gastric emptying, using a liquid meal labelled with 99Tcm DTPA was studied in 6 patients with Crohn's disease who had diarrhoea following resection of the small intestine. Results were compared with those obtained in 6 normal subjects and 6 patients who had classic dumping symptoms following gastric surgery. The rate of gastric emptying of patients with Crohn's disease was similar to that of normal subjects, and differed markedly from gastric emptying in patients with the dumping syndrome (P less than 0 . 001). Diarrhoea in patients with Crohn's disease who have undergone intestinal resection is not due to rapid gastric emptying and would therefore be unlikely to respond to therapeutic measures designed to improve similar symptoms in patients who have the dumping syndrome.
