Abstract:

Coins (86 cases, 74.8%) were the major foreign bodies in metal foreign body of upper digestive tract, followed by button batteries (11 cases, 9.6%), magnetic balls (8 cases, 7.0%), and others (10 cases, 8.6%). The main clinical symptoms were nausea, vomiting, abdominal pain, chest pain, and foreign body sensation, and button battery ingestion and magnetic balls were easy to produce complications.The primary retention sites of metallic foreign bodies were the gastric fundus (75 cases, 65.2%), followed by upper esophageal segment (38 cases, 33.0%) and lower esophageal segment(2 cases, 1.7%).Conclusions:In children′s metal foreign body of upper digestive tract, coins are the most common foreign bodies that are easily retained in the stomach fundus.Button batteries are prone to cause severe complications and should be removed timely.The self-made metallic foreign body extractor in our department can remove coins, batteries, magnetic balls, nails, chains, party emblems and other metallic foreign bodies.It can shorten the operation time, improve the removal efficiency, and featured by active search, strong adsorption, no mucosal damage and removal with the endoscope, which can be widely used in the clinical treatment of metallic foreign bodies.
