[Gastric emptying time with 99mTc-resin solid experiment meal].

Half gastric emptying time (GET1/2) was measured by using radionuclide gamma-photography with 99mTc-resin solid experiment meal. The results were as follows: 1. GET1/2 in the normal controls (10 cases) was 51.62 +/- 3.69 minutes. 2. GET1/2 in mild chronic atrophic gastritis (CAG) patients was 51.68 +/- 9.20 Min, not significantly different with the normal controls (P > 0.05). GET1/2 in 15 cases with moderate and severe CAG was 70.39 +/- 14.86 Min, which was apparently longer than that in normal controls (P < 0.01). 3. There was no significant difference in GET1/2 between carcinoma of the gastric corpus, fundus and cardia (50.77 +/- 2.73 Min) as well as the normal controls (P > 0.05). GET1/2 of the cancer of gastric antrum was 89.06 +/- 19.55 Min, being longer than that in normal controls (P < 0.01). 4. No obvious difference was observed between the GET1/2 of patients with corpus and fundus peptic ulcer (55.36 +/- 6.80 Min.) and the normal controls (P > 0.05). It was apparently longer in patients with antral peptic ulcer (76.62 +/- 16.96 Min.) than in patients with ulcers of corpus, fundus and normal controls (P < 0.01). 5. GET1/2 in patients with duodenal ulcer (42.49 +/- 6.26 Min.) was apparently shorter than those with gastric ulcer and normal controls. 6. GET1/2 in diabetic patients was 70.01 +/- 29, 46 Min, it was obviously longer in those patients with autonomic nervous dysfunction (84.03 +/- 22.31 Min.) than that those without (34.14 +/- 7.90 Min.).(ABSTRACT TRUNCATED AT 250 WORDS)
