Pediatricians and emergency room specialists are routinely faced with the challenge of management of young patients who are suspected to have accidentally swallowed foreign objects. These objects can become a pathologic esophageal or airway foreign body. The persisting esophageal foreign body, one that does not pass spontaneously through the gastrointestinal tract, is suspected based on patient history and clinical symptoms. These often include regurgitation, drooling and unrelenting discomfort worsened by attempts to swallow. However, there are times when persisting esophageal foreign body is asymptomatic. This report describes the utility of using a contrasted esophagram in identifying the presence of a large but asymptomatic persistent radiolucent esophageal foreign object, a ‘‘Lego Man’’.
A 10-year old male whose past medical history was significant only for Attention Deficit Hyperactivity Disorder presented to the Emergency Department six hours after having swallowed a “Lego Man” that he felt may have passed completely. Apart from mild generalized throat discomfort, he was asymptomatic at the time of presentation and at the time of specialty examination: he had no respiratory complaints, no drooling, no dysphagia, nor chest pain. He brought with him an example of the “Lego Man” (Figure 1).
Because it was unclear if this material was radio-opaque or radio-lucent, a plain film of an identical ‘‘Lego Man’’ alone on a radiographic plate was obtained. This demonstrated a partially radiopaque foreign object (Figure 2). Because of the possibility of some degree of radio-opacity based on the plain film, the emergency department obtained a formal posterior-anterior chest radiograph, a formal lateral chest radiograph, and then a KUB radiograph to evaluate for a possible enteric “Lego Man.”
These imaging studies did not reveal the location of the
foreign object (Figure 3).
In this case of an asymptomatic patient with clearly
negative imaging and work up with overall satisfied parents,
the provider was met with the diagnostic dilemma of observant
discharge versus recommendation for further pursuit of the
foreign body with a computed-tomography (risks being cost
and radiation exposure) or operative diagnostic esophagoscopy,
(risks being cost, anesthesia risks and a potentially unnecessary
invasive procedure). A third diagnostic option was entertained:
obtaining barium esophagram. Considering the large size of the
foreign object and the relatively lower cost and X-ray exposure
associated with this imaging modality, the decision was made to
pursue this option. This imaging study clearly outlined the “Lego
Man,” persisting in the cervical esophagus (Figure 4).
The patient subsequently underwent therapeutic operative
esophagoscopy in the operating room. This revealed the
“Lego Man” lodged in the cervical esophagus, just below the
upper esophageal sphincter. The “Lego Man” was removed
atraumatically with very scant excoriation of the esophageal
mucosa. The patient did well in the recovery room and was
discharged home in stable condition.
Pediatric specialists routinely face the challenge of evaluation
and management of young patients who are suspected to have
accidentally swallowed potentially dangerous foreign objects.
The persisting esophageal foreign body is suspected based upon
a parent-provided patient history (most often) and on active
clinical symptoms, which usually include obvious regurgitation,
drooling and unrelenting discomfort worsened by attempts to
swallow. However, there are times when persisting esophageal
foreign body is asymptomatic. In clinical practice, every
otolaryngologist has removed meat impacted for days on end;
our practice has reported disc batteries sitting for days [Evans
& Panella]; and this investigator has observed stricture with
proximal esophageal dilation after a dime was present for an
estimated 6 months. In the setting of an unreliable history and / or an asymptomatic patient, the diagnostic challenge is further
Many foreign objects will pass through the alimentary
tract without causing any harm, however there is a real risk of
morbidity and even mortality with any esophageal foreign object.
Our greatest concern remains the disc battery, wherein “time
is tissue” and sequelae are significant, i.e. tracheoesophageal
fistula, aortic rupture. However, acute upper airway obstruction,
failure to thrive and aspiration of refluxate into the airway
with subsequent aspiration pneumonia remain important
consequences of the undiagnosed esophageal foreign body.
Therefore, each patient should be appropriately worked up and
managed to avoid these, and other, possible sequela.
Beyond history and physical examination, imaging studies
increasingly play a critical role in the first line of assessment as a
part of the medical decision making process. Used appropriately,
imaging can guide further management . The vast majority of
esophageal foreign bodies are radiopaque (coins) , and the
utility of plain radiograph for this diagnosis is well documented.
Radiolucent foreign objects, such as plastic, organic material
and glass, present greater challenge with plain films that can
provide a false sense of reassurance. The internationally popular
Lego is considered a radiolucent plastic toy, based upon its
relative invisibility on radiograph at physiologic settings .
Retrospectively, our radiologists were able to capture “Lego
Man’s” image with the potentially false reassurance of radioopacity
because the image was obtained separate from the
patient and the X-ray was coned specifically for the toy.
Studies have suggested that spiral CT serves as an alternative
imaging modality to identify the presence of radiolucent foreign
objects in the esophagus or trachea . Spiral CT does require
a cooperative child and a thorough interpretation. As an
alternate, providers may forego imaging and proceed directly
to the operating room. This raises several concerns in the
parent-doctor discussion. One concern is NPO-status and airway
management in the acute foreign body. Another is the parental
concern for performing a potentially unnecessary and possibly
costly invasive diagnostic test.
In the modern era, parents are carefully following their
child’s risk: benefit analysis regarding studies and interventions.
Publications reporting increased concerns for unnecessary
anesthesia experience permeate both the scientific literature
and the lay press. As the deductibles for third-party payers have
increased, parents have more carefully rationed the distribution
of the healthcare dollars. And culturally, the last 20 years have
demonstrated a shift away from paternalistic medicine towards
joint medical care planning in partnership with parents. These
interactive forces add challenges for the provider who is working
to make a safe, efficient, and cost-effective decision regarding the
optimal acute evaluation and management of the asymptomatic
patient (Table 1).
It is well documented that pricing varies with locality and the contracted
payor-biller relationship. This reflects assessments of billing patterns
prior to institution of “facility fee” charges in addition to surgical
anesthetic and operative time fees.
This case illustrates that even an asymptomatic patient
deserves a high index of suspicion for persistent esophageal
foreign body, and barium esophagram can be critical in
identifying the presence of such an object for surgical decision
making. Though availability of urgent fluoroscopy may be
limited, there is overall lower radiation exposure than a CT scan
[6-8], it is less costly than a negative operative endoscopy ,
and it may be safer than observant discharge.
