title: Discrepant pattern of solid and liquid gastric emptying in Chinese patients with type II diabetes mellitus.
abstract: While abnormal gastric emptying has been widely reported in patients with diabetes, its clinical relevance is still uncertain. We conducted scintigraphic gastric emptying studies in patients with Type II diabetes mellitus who had symptoms suggestive of delayed gastric emptying in an attempt to evaluate the incidence of abnormal gastric emptying and to assess the clinical parameters of the different patterns of gastric emptying. Seventy male diabetic patients were included in the study. The patients were divided into four groups according to the results of liquid and solid gastric emptying: group 1, normal liquid and solid emptying (n = 22); group 2, normal liquid but delayed solid emptying (n = 30); group 3, delayed liquid but normal solid emptying (n = 7); group 4, delayed liquid and solid gastric emptying (n = 11). To assess clinical significance, we compared duration of disease, status of blood sugar control, presence or absence of vascular complications and of peripheral neuropathy among the four groups. Of the 70 patients, 18 (25.7%) showed delayed liquid gastric emptying and 41 (58.6%) delayed solid gastric emptying. There were no significant differences in the clinical parameters of the four groups, except that patients with good sugar control were likely to have normal liquid gastric emptying. Based on the results of this study, delayed solid gastric emptying is more common than liquid gastric emptying in symptomatic Type II diabetes mellitus patients. Of the different patterns of gastric emptying, delayed liquid gastric emptying with normal solid gastric emptying is the most unusual. For Type II diabetic patients with symptoms suggestive of delayed gastric emptying, both liquid and solid gastric emptying studies should be performed.
