Acute esophageal coin ingestions: is immediate removal necessary?

AIMS: Coins are the most commonly encountered foreign body ingestions presenting to the emergency department (ED). The purpose of our study was to retrospectively evaluate a new institutional protocol implemented in 1998, in which healthy patients with acute (less than 24 h) coin ingestions located below the thoracic inlet, were observed at home with next-day follow-up. If repeat radiographs revealed a persistent esophageal foreign body, then the coin was removed.

METHODS: The charts of all patients who presented to the ED with a complaint of esophageal foreign body were reviewed from 1 January 1998 until 31 December 2001. Patients were excluded if they had non-acute ingestions, known esophageal pathology, severe symptoms such as stridor or inability to tolerate oral fluids, or incomplete records.

RESULTS: Of 31 patients with esophageal coin ingestions, 16 had coins above the thoracic inlet. Three of these patients were asymptomatic and all experienced spontaneous coin passage into the stomach within 2 h of ED presentation while awaiting coin removal. There were eight eligible patients with coins located below the thoracic inlet. Three of five patients with mid-esophageal coins experienced spontaneous coin passage while the remaining two required coin removal on next-day follow-up for persistent esophageal coins. Three of three patients with distal-esophageal coin ingestions experienced spontaneous coin passage. There were no complications in any of the patients who underwent delayed coin removal either due to the procedure itself or to a delay in therapy.

CONCLUSIONS: Patients with acute esophageal coin ingestions may experience spontaneous coin passage and therefore, patients with coins located below the thoracic inlet with minor symptoms may be candidates for next-day follow-up. If repeat radiographs reveal a persistent esophageal coin, then the coin should be immediately removed. Furthermore, asymptomatic patients with coins above the thoracic inlet should undergo repeat radiographs in 2-5 h, as spontaneous coin passage may occur. Our protocol may also be more convenient and cost-effective as patients can be observed at home.
