Meckel Scan Quality After Antacid Pretreatment
| Observed 99mTc-pertechnetate release | Oral ranitidine, 18–150 mg, n = 19 | Intravenous ranitidine*, 5–62 mg, n = 98 | Intravenous esomeprazole*, 10–40 mg, n = 23 |
|---|---|---|---|
| Absent in duodenal and intestinal lumen | 3 | 23 | 11 |
| Activity in duodenal or intestinal lumen | 3 | 13 | 4 |
| Activity in both duodenal and intestinal lumen | 13 | 62 | 8 |
↵* Esomeprazole resulted in significantly better scan quality than intravenous ranitidine (P = 0.034).
