Prevalence of delayed gastric emptying using various parameters
| Parameter | Prevalence |
| Scintigraphy | |
| Scintigraphic t50 (≥89.8 min) | 38% (9/24) |
| Retention at 60 min (>73%) | 38% (9/24) |
| Retention at 120 min (>32%) | 50% (12/24) |
| Retention at 180 min (>13%) | 54% (12/23) |
| Breath test | |
| BTt50 (>99.5 min) | 57% (13/23) |
| GEC (<3.03) | 55% (12/22) |
| Gastric residual volumes (GRVs) | |
| GRV>150 ml in 24 h | 46% (10/22) |
| GRV>250 ml in 24 h | 27% (6/22) |
BT, breath test; GEC, gastric emptying coefficient; t50, half emptying time.
