Surgical treatment of multiple magnet ingestion in children: A single-center study

Table 2 Cases experiencing self-discharge of magnetic foreign bodies

Cases without gastroscope, without surgery, whose all magnetic foreign bodies were discharged by themselves
No.	Age (yr)	DBIG (day)	NIM	Type of magnet
1	4	3, 61	2	Disk magnet
2	5	3	3	Magnetic bead
3	5	5	4	Magnetic bead
4	6	2	4	Magnetic bead
5	7	2	2	Magnetic bead
6	8	1	7	Magnetic bead
7	8	3	2	Strip magnet
8	10	2	2	Magnetic bead
Cases of intestinal magnetic residue after gastroscopy, which were discharged by themselves
No.	Age (yr)	DBIG (d) DBGD (d)	NIM/NIMR	Type of magnet
1	10	2/1	3/1	Magnetic bead
2	13	5/4	4/2	Magnetic bead

¹The child swallowed two magnets at different times, which were discharged on the third and sixth days after swallowing. DBIG: Days between ingestion and discharge; DBGD: Days between gastroscopy and discharge; NIM: Number of ingested magnets; NIMR: Number of intestinal magnetic residues.
