SummaryAs an intravenous injection is not used in our premedication of infants and children for small bowel biopsy, we investigated what effects oral metoclopramide might have on small bowel biopsy procedure time and fluoroscopy time. Eighteen infants and children were randomized to receive 0.2 mg/kg metoclopramide or placebo orally, 40–45 min before starting the procedure, and the procedure was monitored for the time required for the biopsy capsule to reach the pylorus, to cross into the proximal duodenum, and to reach the biopsy site. Corresponding fluoroscopy times were recorded as well. Mean total procedure time was less for those treated with metoclopramide, 43.7 ± 11 min, than for controls, 86.5 ± 15.5 min (p < 0.005). Mean total fluoroscopy time was also less in treated patients (40.9 ± 11.5 s versus control 84.4 ± 17 s) (p < 0.005). The effect of metoclopramide occurred in the interval for the biopsy capsule to cross the pylorus (15.1 ± 2.7 min versus control 60.8 ± 16.6 min) (p < 0.005) and in fluoroscopy time required (15.1 ± 1.9 s versus control 46 ± 17 s) (p < 0.005). Oral metoclopramide is effective in reducing procedure time for small bowel biopsy, and its predictable action facilitates reduction in fluoroscopy exposure.
