Phosphate enemas were applied for chronic constipation for a long period of time. This study aims to evaluate the effect of a single dose of phosphate enema on bowel movements in patients who suffer from foreign body ingestion. Materials and Methods: Forty consecutive patients admitted to our emergency unit for foreign body ingestion were randomized into two groups. Patients in both groups were followed up with daily imaging and physical examinations. Cases in Group SP received daily doses of sodium phosphate enemas, while Group C did not. Demographics, number of X-rays, radiation dose, and period of the foreign body passage were recorded and compared between two groups. Also, data of patients who ingested pins (Group P) were compared with of those who ingested other materials (Group O). Results: There was no statistical difference between groups (Group SP vs. Group C and Group P vs. Group O) comparing demographics, number of X-rays, total amount of radiation doses (p > 0.05 for all comparisons). The period of foreign body passage was shorter in Group SP (3.4 ± 1.6 days vs. 6.2 ± 3.8 days;p = 0.005). Also, patients who ingested pins were compared to patients who ingested other materials. Pins were ingested by 23 (65%) patients. These were older (16.6 ± 9.4 years vs. 4.8 ± 3.5 years;p = 0.001) and generally females (78.3% vs. 29.4;p = 0.006). Contrary to the other cases, pins were less frequently confirmed in stool in patients who ingested pins (p = 0.02). Conclusion: A single dose of phosphate enema use may hasten the passage of the foreign bodies. Ingestion of pins is the more common especially in young females. The evacuation of pins is generally recognized with direct examination of the stool, so daily imaging may not be necessary for this group of patients.展开更多
