When treating patients with lung illnesses, clinicians and medical professionals need a bronchoscopy as a key tool. Flexible bronchoscopy has become a crucial technique for the diagnosis and treatment of patients with lung illnesses. In therapeutic circumstances, rigid bronchoscopy can be especially beneficial. This exercise explains the bronchoscopy indications and contraindications and emphasises the function of the interprofessional team in the treatment of patients with airway illnesses.
A flexible bronchoscope with a fibre optics system, camera, and light source enables direct, in-the-moment observation of the airways. The respiratory system can be examined using it, starting with the nose or oral cavities and moving on to the sub-segmental bronchi [1]. Ultrasonographic examination of mediastinal structures, such as lymph nodes, as well as the pulmonary periphery is made possible by advanced bronchoscopic techniques, such as endobronchial ultrasonography.
Hemoptysis, persistent, unexplained cough, stridor, mediastinal or hilar lymphadenopathy, lung cancer nodal staging, pulmonary infiltrates, pneumonia, atelectasis, suspected tracheomalacia, suspected tracheoesophageal fistula, and post-lung transplant surveillance [2]. Removal of foreign objects, placement of tracheal and bronchial stents, balloon dilatation of airway stenosis, ablation or debulking of endobronchial tumours, management of persistent air leak or bronchopleural fistula, challenging intubations, bronchoscopic lung volume reduction surgery, bronchial thermoplasty for asthma, whole lung lavage, and as an adjunct during percutaneous tracheotomy are all examples of procedures where this By isolating the bleeding lung with a bronchial blocker during bronchoscopy, hemoptysis can be temporarily controlled, although the procedure has a low therapeutic yield.
In the operating room, rigid bronchoscopy was used for therapeutic purposes. Under general anaesthesia, a rigid bronchoscope was introduced into the airway. An automatic jet ventilator was used to ventilate the patients. The stiff bronchoscope's principal lumen was used to introduce a rigid telescope, a flexible bronchoscope, and other tools. Controlled Radial Expansion (CRE) pulmonary balloon dilators were used to dilate the airways. With flexible or rigid forceps, or by coring out with a rigid bronchoscope, tumour debridement was carried out. Atomic Plasma For tumour ablation or hemostasis, coagulation and rigid or flexible electrocautery were used as the main heat modalities. In a few instances, the potassium-titinyl-phosphate laser was also employed [3].
Patients with both malignant and nonmalignant pulmonary illnesses are at an increased risk for central airway obstruction (CAO), which has been linked to severe morbidity and a poor prognosis. It may also develop as a consequence of nonmalignant conditions such post-intubation tracheal stenosis and post-lung transplantation airway stenosis. It has been observed to impact up to 20–30% of patients with primary or metastatic lung cancer [4]. The effectiveness of present procedures has not been proved, nor is optimal management strategies clearly defined. Radiation therapy and chemotherapy are currently the main therapeutic methods used to treat malignant CAO, while bronchoplasty and surgical removal of the primary lesion are typically used to treat nonmalignant CAO.
When the hazards of the procedure outweigh the advantages, bronchoscopy should not be done. The prescribing pulmonologist does a case-by-case risk-benefit analysis. Severe baseline hypoxia, hemodynamic instability, a recent myocardial infarction, serious hypoxia, an uncooperative patient, a severe bleeding condition, or an inexperienced operator is only a few examples of contraindications. Patients with lung cancer and those who have developed pulmonary metastases from other cancers, such as breast, colon, and renal cell cancer, frequently experience malignant airway obstruction. Malignant airway obstruction can be classified as endobronchial, extrinsic compression, or mixed patterns. Endobronchial obstruction can be treated with ablative methods that damage tissue. Lasers, electrocautery, argon plasma coagulation (APC), photodynamic treatment, microdebriders, and cryotherapy are examples of ablative procedures. For patients with extrinsic compression, stents are the main treatment option. Usually, numerous modalities are needed for mixed patterns. The kind of bronchoscopy employed (flexible vs. rigid), preferred ablative technique (e.g., laser vs. electrocautery), and stent strategy and preference differ greatly between bronchoscopists' practises (eg, silicone vs metal).
Since the majority of patients have advanced, incurable disease, therapeutic bronchoscopy for malignant central airway blockage is primarily a palliative intervention. The majority of patients gain from changes in quality of life rather than length of life, even if therapeutic bronchoscopy in this scenario may in fact modestly lengthen life for some patients (e.g., allowing them to get off the ventilator). It is crucial to take into account both technical success and the following effect on dyspnea and health-related quality of life when comparing the efficacy of different therapeutic bronchoscopy procedures [5].
The potential improvements in HRQOL must then be compared to the intervention's dangers. In this investigation, we discovered that while technique varied significantly between centres, technical success was typically attained. The rate of technical achievement varied between centres, but these variances were not very significant. Technical achievement, however, did not necessarily translate into a significant reduction in dyspnea. Patients with lobar disease had a lower likelihood of improving, whereas those who were more breathless at baseline had a higher likelihood. Similar to this, individuals who had more dyspnea at baseline had the greatest improvements in HRQOL, whereas those with lobar illness showed less improvement. Higher ASA scores and lower ASA scores were both linked to an improvement in HRQOL.
