BACKGROUND: A simplified report of gastric retention values at select times is now recommended for scintigraphic gastric emptying test (GET). AIMS: The purpose of this study was to assess correlation between severity of gastroparetic symptoms and all variables of GET, compared to select variables in clinical use. METHODS: This was a prospective study of patients referred for scintigraphic GET. The Gastroparesis Cardinal Symptom Index questionnaire was obtained prior to the scintigraphy. Variables determined were lag time, half emptying time (T1/2), retention at 30 min, 1, 2 and 4 h. Statistical analysis was by Spearman rank correlation and Wilcoxon rank test with a significance set at p ≤ 0.05. RESULTS: Seven hundred seventeen patients had GET from 03/09 to 03/11. Results are from 325 patients who did not take medications known to affect GET were analyzed (64.9 % females, mean age 47 ± 18.9 years, 21.8 % diabetics, 78.2 % non-diabetic, of which 7.6 % were post-surgical, primarily post-fundoplication). Combined gastric retention at 2 and 4 h detected delayed GET in 83.5 % non-diabetics and 76.6 % of diabetics. Rapid GET was present in 11 % of patients at 30 min and 4 % at 1 h. Significant positive correlation was observed between nausea, vomiting, loss of appetite and variables of GET, but not with the half-time of emptying (T1/2). Bloating negatively correlated with retention at 2 h. There was no association between duration of symptoms and GET variables. CONCLUSIONS: Gastroparetic symptoms correlate with different retention times of GET, but not with T1/2. However, symptoms poorly distinguish between categories of gastroparesis or status of gastric emptying. Delayed GE is best detected by 2 and 4 h retention times, while 30 min and 1 h retention times detect rapid GE.
