Data including demographic characteristics, types of foreign bodies, imaging findings, complications, and treatment methods were collected. Foreign bodies were classified into six categories. Retention time was defined as the interval from the confirmed or most suspected time of ingestion to the time of imaging examination. Interobserver agreement for ultrasound interpretation was assessed using Cohen's\n                      <jats:italic>\u03ba<\/jats:italic>\n                      between two senior radiologists.

Magnetic beads were most common (54.9%), followed by coins (12.7%) and water-absorbing beads (8.5%). The small intestine was the main impaction site (41.5%). Complications occurred in 50 patients (70.4%): perforation in 32 (45.1%) and obstruction in 26 (36.6%). Magnetic beads caused perforation in 71.8%; water beads caused obstruction in 100%. Ultrasound effectively detected radiolucent foreign bodies, whereas plain radiography did not. Independent risk factors for complications included sharp\/corrosive foreign bodies (OR\u2009=\u20095.12), retention time &amp;gt;24\u2005h (OR\u2009=\u20094.87), upper gastrointestinal location (OR\u2009=\u20093.21), and symptomatic presentation (OR\u2009=\u20093.94) (all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.01). Magnetic beads independently predicted complications (OR\u2009=\u20096.43,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001). Surgery was required in 69.0%, endoscopy in 12.7%, and spontaneous passage in 18.3%.
