tertiary care academic hospital. Population: 7,089 adults (age >18 years), including 949 (15%) advanced elderly (age >75 years), who underwent flexible bronchoscopy between January 1995 and June 2007.
in those patients with foreign body aspiration (FBA) (n = 20), a comparison of multiple clinical characteristics based on defined age groups (group 1, age <75 years and group 2, age >75 years) was performed.
FBA requiring bronchoscopic removal was greater than three and a half times more likely in patients aged >75 years compared to those younger (OR 3.78, CI 1.4-10: P <0.05). Flexible bronchoscopy was 87.5% effective in the removal of foreign bodies in the advanced elderly and associated with no increase in adverse events.
bronchoscopic removal of foreign bodies is more likely in the advanced elderly when compared to those younger. This implies that this population may be most at risk. Flexible bronchoscopy is a safe and effective initial diagnostic and therapeutic approach in this age group.

ABSTRACT: To evaluate the efficacy and safety of fibreoptic bronchoscopy in the elderly, the bronchoscopy records of 1000 patients were retrospectively reviewed. Of these, 423 were in-patients aged 65 years or over. This population was further subdivided into 'young' elderly (65-74 years old) and 'old' elderly (75+ years old). The indications for bronchoscopy in each group were similar and included haemoptysis, chest radiographic changes suggestive of collapse or consolidation, and hilar or paratracheal shadowing. The results in each group were also comparable and bronchoscopy was not tolerated in only five. A visible tumour was present in 165 patients. We conclude that, like upper gastrointestinal endoscopy, fibreoptic bronchoscopy in the elderly is safe, well tolerated and has a significant diagnostic yield.Age and Ageing 08/1987; 16(4):229-33. · 3.11 Impact Factor

ABSTRACT: The flexible fiberoptic bronchoscope was used to treat bronchial foreign bodies in 33 adults. The length of time that the foreign body was in the lung was less than 1 wk in six (acute group), more than 1 month in 21 (chronic group), and uncertain in two (uncertain group), and the foreign body was an endogenous broncholith in four patients (broncholith group). The foreign bodies were nonfragile, solid matter in most cases and they frequently had sharp projections on them. Granulations around the foreign body were common in the chronic group, but there was no correlation between the length of time the foreign body was in the lung and the amount of granulation or the number of the bronchoscopies needed for diagnosis or management. The granulations did not bleed easily on biopsy or during removal of the foreign body. In fact, they receded if several pieces were removed, making the foreign body much easier to recognize and to retrieve in the next bronchoscopy (about 1 wk later). After removal of the foreign body, the residual granulations regressed, and the bronchial lumen became more patent. The mortality, morbidity, and complication rates were very low, whereas the success rate was high. We conclude that flexible fiberoptic bronchoscopy is practical and safe in retrieving bronchial foreign bodies in adult patients.The American review of respiratory disease 01/1990; 140(6):1734-7. · 10.19 Impact Factor

ABSTRACT: The safety and usefulness of fibreoptic bronchoscopy in the elderly was assessed retrospectively in 204 consecutive patients aged 70 and over. One third of patients were examined as day cases. A bronchial tumour was seen in 67% patients, and biopsies showed malignancy in 78% of these cases. Certain knowledge of a diagnosis of bronchial carcinoma helped in the management of the elderly patient. Fibreoptic bronchoscopy proved to be safe in the presence of marked ventilatory impairment. A prospective questionnaire study in 114 patients showed that most patients found the procedure acceptable and would agree to a repeat if necessary and this was largely independent of age.Age and Ageing 06/1981; 10(2):127-31. · 3.11 Impact Factor

Objectives: to define the likelihood and establish the overall safety and effectiveness of flexible bronchoscopy in the removal
of foreign bodies in the advanced elderly compared to those younger.
Design: a retrospective case–control analysis.
Setting: tertiary care academic hospital.
Population: 7,089 adults (age >18 years), including 949 (15%) advanced elderly (age >75 years), who underwent flexible
bronchoscopy between January 1995 and June 2007.
based on defined age groups (group 1, age <75 years and group 2, age >75 years) was performed.
Results: FBA requiring bronchoscopic removal was greater than three and a half times more likely in patients aged >75 years
compared to those younger (OR 3.78, CI 1.4–10: P <0.05). Flexible bronchoscopy was 87.5% effective in the removal of
foreign bodies in the advanced elderly and associated with no increase in adverse events.
Conclusion: bronchoscopic removal of foreign bodies is more likely in the advanced elderly when compared to those
younger. This implies that this population may be most at risk. Flexible bronchoscopy is a safe and effective initial diagnostic
and therapeutic approach in this age group.

Foreign body aspiration (FBA), defined as the introduction
of a large particulate material into the tracheobronchial tree,
is a rare event that increases with age [1–4]. Despite this age
association, the risk of FBA in older adults remains poorly
defined. The presence of cerebrovascular disease, heart

phagia, dementia or sedating medication that affect the level
of consciousness all have been suggested to predispose older
adults to aspiration [5–9]. Whether these conditions affect
the likelihood of FBA remains unknown. Without prompt

choscopy (FB) is regularly performed to confirm and iden-
tify foreign bodies and is effective in FBA removal [12–14].
Althoughlarge case studies on FBA in adults havebeen pub-
lished [1–4], there is no specific literature addressing bron-
choscopic removal of foreign bodies in older adults despite
previous reports that bronchoscopy in this age group is gen-
erally safe and well tolerated [15–21]. The most common
indications reported for FB in older adults are pneumonia,
pulmonary infiltrates and possible neoplasm . Institu-
tional experience at Wake Forest University Baptist Medical
Center (WFUBMC) suggested that both diagnostic and ther-
apeutic bronchoscopic removal of foreign bodies occurred
study was designed to determine whether the very old were
more likely to undergo bronchoscopic removal of foreign
bodies and whether FB provides a safe and effective method
of foreign body removal in this age group. We reviewed the
last 12.5 years of experience at WFUBMC with therapeutic
bronchoscopy for the removal of foreign bodies (January
A retrospective case–control study examining broncho-
scopies related to FBA in very old adults was performed
at WFUBMC, a tertiary care academic medical centre.
Procedural logbooks from the bronchoscopy laboratory
were reviewed, documenting all adult bronchoscopies,
defined as age 18 years or older, from January 1995 to
June 2007. All procedures with the indication of FBA, both
suspected and known, were identified. A review of the paper
chart or electronic medical record was then performed to
verify whether suspected cases were true FBA events. Only
clearly documented or proven FBA events were included in
the final analysis. After all cases were identified, the medical
record was reviewed, and the following clinical characteristic
data were collected: age, gender, nature of material aspirated,
the presence or absence of radiological changes, presenting
symptoms, the presence of possible contributing risk factors
(underlying neurological disease, congestive heart failure or
pulmonary disease), the mechanism of foreign body removal
(flexible vs. rigid bronchoscopy), device (s) utilised for
removal, dosage and type of sedation utilised, complications
of bronchoscopy and outcome of the FBA event (survival).
Lastly, age and gender for all adult bronchoscopies per-
formed at WFUBMC during this same time period were
documented for comparison. Bronchoscopic procedures
identified due to recording errors or when the information
was protected. Safety of bronchoscopy was assessed by
reviewing procedural documentation (beginning from start

The clinical characteristics of patients are summarised in
Table 1. Between the two groups, choking was the only sta-
tistically significant presenting symptom, occurring in 50%
Fatal and non-fatal FBA occur rarely but are more often
present in the extremes of life (i.e. the very young and very
old) [1–4, 22]. The exact incidence of FBA in older adults
is not known. It is presumed that many cases go unrecog-
nised or resolve (expectorated) without medical attention.
Thus, defining the true incidence of FBA is not practical.
This study is the first to attempt to define the likelihood
of bronchoscopic removal of foreign bodies as it relates to
older age. Bronchoscopy performed to remove foreign bod-
ies was more than three and a half times as likely to occur in
those ≥75 years of age compared to those <75 years. This
implies that the likelihood of FBA may also be higher in
this age group compared to younger patients. Other studies
have suggested this as well. In a large 33-year retrospective
analysis of 60 adult patients, Limper et al. found that 42%
of FBA events requiring bronchoscopic removal occurred in
the seventh decade of life with a median age of 60 years .
with FBA and found that 19/43 events (40%) occurred in
the sixth decade . Baharloo and colleagues described their
and found a peak incidence occurring in the sixth decade of
life (28% of all adult cases) .
The 40% prevalence of FBA identified in the very old
adults in this study is in agreement with Limper, but does
differ by suggesting a higher median age than previously
reported (72 years compared to 60 years) . The increase of
an ageing population since Limper’s study may explain this
identified in this study is similar to previous studies (1.4–
2.86 FBA events/year) [1–4]. The peak prevalence of FBA
events occurred in the age group of 75–84 years and is also
comparable to Limper’s findings .
FB as an initial approach to foreign body removal was
safe and efficacious in both groups. The success of FB in
the removal of foreign bodies achieved in this study is sim-
ilar to previous reports [12–14]. More importantly, no dif-
ferences were found in procedure-associated complications
findings suggest that FB should be considered as the initial
diagnostic procedure as well as the therapeutic modality of
choice in the removal foreign bodies in very old adults. To
our knowledge, this is the first study to address the safety of
FB in FBA in older adults.
In reviewing clinical characteristics, choking was found
to occur only in group 2 patients and achieved a statistical
significance when compared to group 1. Choking combined
with intractable cough is commonly referred to as ‘pene-
tration syndrome’. Limper’s study suggested an occurrence
of penetration syndrome in both children and adults which
was reported in 49% of cases at initial presentation . It is
unclear in this study why penetration syndrome was found
patients’ symptoms. Although choking, cough and dyspnoea
do occur frequently, no symptom is reliably sensitive or spe-
cific for FBA. A presumptive diagnosis of FBA was based
upon a witnessed event or the patient history in the majority
of the cases presented in this study. Without a supportive
history, the diagnosis of FBA was often delayed by days to
month. An eventual diagnosis of FBA was obtained only
after persistence of respiratory symptoms, suggestive radio-
logical changes or an increased clinical suspicion. Therefore,
practitioners who care for very old adults should maintain a
