serious infection, bronchoscopy may be performed to get better samples from a particular area of the lung. These samples can be looked at in a lab to try to find. With the development of new instruments and the refining of new techniques, flexible bronchoscopy has become one of the most frequently. British Thoracic Society guideline for diagnostic flexible bronchoscopy in adults. I A Du Rand,1 J Blaikley,2 R Booton,3 N Chaudhuri,4 V Gupta,2 S Khalid,5 S.

Having said so, there are potential scenarios in which this additional information may become valuable. Endobronchial ultrasound versus mediastinoscopy for mediastinal nodal staging of non-small-cell lung cancer. A Fogarty balloon 60 , endobronchial blocker or a balloon dilator may be used to tamponade the airway to control the bleeding while the bronchoscope is thawing ex vivo. Successful endobronchial foreign body retrievals are also carried out using flexible bronchoscopy. Hence, considering that it also has a more favorable safety profile in comparison with transbronchial biopsies , EBUS-TBNA is likely the initial method of choice to diagnose stages I and II sarcoidosis. Revised ESTS guidelines for preoperative mediastinal lymph node staging for non-small-cell lung cancer. With the evolution of pulmonology over the years, there has been a simultaneous evolution in the indications and applications of flexible bronchoscopy.

Due to the small number of cases encountered, there is no standard in the management of these cases.

Recent advances in diagnostic bronchoscopy

Therapeutic methods include flexible or rigid bronchoscopy. Flexible bronchoscopy can be used successfully in non-life-threatening cases, in the case of intubated patients or in those with cervical instability 2. Therefore, it could represent the cornerstone of the diagnosis, but should only be considered as a treatment method if the bronchologist has the necessary experi-ence and skill, as well as a thoracic surgery service with staff available and resuscitation equipment nearby 5.

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. On clinical grounds, the patient experienced persistent cough with mucopurulent expectoration, with a lack of steady improvement following appropriate bronchodilator therapy.

Pulmonary function tests showed a mixed airway disease, with mild restriction and mod-erate obstruction. The chest X-ray appearance was one of a small quantity pleurisy with an elevated right hemidiaphragm. The patient refused the flexible bronchoscopy at first, but returned after one month with worsened symptoma-tology and he accepted the examination.

A foreign body was found inclavated in the right lower lobe bronchus, a cherry pit Figure 2 , surrounded by granulation tissue with distal secondary suppuration. The FB was mobilized proximally, in the intermediate bronchus, and then, with the use of the Dormia basket, the cherry pit was tightly grasped Figure 3 and successfully removed, together with the bronchoscope.

A detailed medical history that raises clinical suspi-cion of aspiration is an essential step in the diagnosis of tracheobronchial FB. Knowing the timing of the event and the nature of the FB makes it easier to extract it.

In patients with neurological and psychiatric disorders, with a possible decrease of the pharyngeal and glottic protective reflexes, FB aspiration may be suspected incase of a sudden onset of respiratory symptoms. 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.

Flexible Bronchoscopy is an ideal training manual for all respiratory and pulmonary physicians, as well as trainees and residents working in the field of respiratory medicine, who need to develop the skill of interventional bronchoscopy.

The evolution of flexible bronchoscopy: From historical luxury to utter necessity!!

Flexible Bronchoscopy , Third Edition Editor s: Francis Turner Jr. First published: Print ISBN: This number of the journal presents two studies 1,2 that describe the experience of two Spanish Intensive Care Units with flexible bronchoscopy..

Globally, both studies confirm that the technique is useful, with both diagnostic microbiological studies of respiratory infection, identification of the origin of hemoptysis, etc. Likewise, flexible bronchoscopy has been shown to be very effective as an aid to other procedures such as selective intubation or visual control during percutaneous tracheostomy.

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 8 mm 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.
