cine subspecialties such as cardiology and gastroen- terology.

ABSTRACT. Flexible bronchoscopy is an essential, established and expanding tool in respiratory medicine. Its practice, however, needs to be.
Considering these studies together with previous publications, it is notorious that although a large percentage of microbiological studies prove negative, flexible bronchoscopy makes a significant contribution to patient clinical management in almost one-half of all cases in which the technique is indicated.
There are practically no strict contraindications to bronchoscopy in the Intensive Care Unit.
Nevertheless, there are situations characterized by a marked increase in risk in which the advisability of bronchoscopy should be assessed on an individualized basis, according to the benefit expected from the procedure. In this context, serious coagulation disorders, very severe and refractory hypoxemia, intense hemodynamic instability despite the use of vasoactive drugs, uncontrolled arrhythmias or acute myocardial ischemia are all situations in which bronchoscopy is not advisable except when its use implies important potential benefit e.
Patient ventilation with a tube under 8mm in diameter is likewise not a formal contraindication. In fact, with adequate material and adopting the pertinent precautions, 7-mm and even smaller tubes allow us to perform bronchoscopy with fiber bronchoscopes of standard size and offering similar efficacy and safety results.
In addition, there are bronchoscopes of smaller caliber that allow us to maintain a good number of the commented indications in Pediatric Intensive Care Units. The most common indication of flexible bronchoscopy in the two mentioned studies was the collection of respiratory samples for microbiological study in patients with clinically or radiologically suspected respiratory infection. An early and specific etiological diagnosis of nosocomial pneumonia or ventilator associated pneumonia, or in patients with comorbidities or immune suppression, is of great prognostic relevance.
In this sense it should be remembered that bronchial aspiration, and particularly bronchoalveolar lavage and telescopic protected catheter bronchial brush, are the most widely used techniques.
In any case, it is necessary to apply the required quality controls in each procedure, in order to guarantee that the bacterial burden is representative. Bronchoalveolar lavage implies an important dilution effect; consequently, in order to assume probable pneumonia, we must perform a cell count squamous epithelial cells and percentage of neutrophils and inflammatory cells that allows the sample obtained to be regarded as optimum.
The obtainment of biopsies via bronchoscopy can also be useful in application to both endobronchial lesions bronchial biopsy and to lung parenchyma transbronchial biopsy.
In the present case, the isolated high level of GGT could indicate chronic alcohol consumption, with the possible aspiration of the kernel during an episode of intoxica-tion, the patient reporting the consumption of cherry liqueur.
If the patient does not recall the episode of aspiration, the diagnosis may be missed and the FB may be detected during a flexible bronchoscopy performed in order to investigate symptoms ascribed to other pathologies such as hemoptysis, chronic cough, relaps-ing pneumonia, or uncontrolled asthma 6.
Rigid bronchoscopy performed under general anes-thesia is the traditional method used to remove FB, allowing for a better visualization and using various available extraction tools. Smaller FB are extracted through the rigid bronchoscope and the larger ones are clamped with rigid forceps, being brought to the end of the bronchoscope and extracted together with it.
Fluoroscopy is also a useful tool. The disadvantages of the rigid bron-choscopy are represented by a longer learning curve and the possibility of complications such as laryngeal spasm, bleeding or laryngeal tracheal dilation 7. It remains strongly indicated in impacted foreign bodies, in asphyx-iating ones and after multiple attempts of extraction by flexible bronchoscopy.
An important step when deciding to use the flexible bronchoscope is to evaluate the need for an endotracheal tube to secure the airway. It can be with-drawn along with the bronchoscope when the FB has an increased size. Depending on the nature of the aspirated object, the necessary tools for removal are the following: In the case of sharp objects, these could be extracted by pointing the sharp edge towards the forceps to avoid damage to the airway wall.
Laryngospasm, stridor and obstruction of the airway are some of the complications that may occur. Local anesthesia of vocal cords, along with conscious sedation with anxiolytics and narcotics are necessary to prevent complications and ensure patient comfort.
The possibility of extraction under these conditions is a great advantage for using the flex-ible bronchoscope. The remaining granulation tissue may require a three-week cortisone treatment and nebu-lisers. In cases of remnant granulation tissue cryother-apy, electrocauterization or plasma argon coagulation can be used for its removal.
In conclusion, flexible bronchoscopy is the gold standard method for the diagnosis of FB aspiration, but it can also be reliable for the extraction, even though rigid bronchoscopy is the gold standard method used in the management of these cases.

Case presentation A year old patient diagnosed with COPD-asthma overlap and arterial hypertension was referred for the evaluation of a calcified mass in the intermediate bron-chus as seen on a native computer tomography of the thorax.
Discussion A detailed medical history that raises clinical suspi-cion of aspiration is an essential step in the diagnosis of tracheobronchial FB.
