Abstract
Pediatric lung transplantation represents a treatment option for children with advanced lung disease or pulmonary vascular disorders who are deemed an appropriate candidate. Pediatric flexible bronchoscopy is an important and evolving field that is highly relevant in the pediatric lung transplant population. It is thus important to advance our knowledge to better understand how care for children after lung transplant can be maximally optimized using pediatric bronchoscopy. Our goals are to continually improve procedural skills when performing bronchoscopy and to decrease the complication rate while acquiring adequate samples for diagnostic evaluation. Attainment of these goals is critical since allograft assessment by bronchoscopic biopsy is required for histological diagnosis of acute cellular rejection and is an important contributor to establishing chronic lung allograft dysfunction, a common complication after lung transplant. Flexible bronchoscopy with bronchoalveolar lavage and transbronchial lung biopsy plays a key role in lung transplant graft assessment. In this article, we discuss the application of bronchoscopy in pediatric lung transplant evaluation including historical approaches, our experience, and future directions not only in bronchoscopy but also in the evolving pediatric lung transplantation field. Pediatric flexible bronchoscopy has become a vital modality for diagnosing lung transplant complications in children as well as assessing therapeutic responses. Herein, we review the value of flexible bronchoscopy in the management of children after lung transplant and discuss the application of novel techniques to improve care for this complex pediatric patient population and we provide a brief update about new diagnostic techniques applied in the growing lung transplantation field.

Abstract
Transbronchial biopsy (TBB) is one of the commonly performed procedures by pulmonologists in everyday practice. Although the procedure has a very low-risk profile, complications often develop in certain patients. Pneumothorax is one such complication pertaining to TBB. As only a small percent of procedures get complicated by pneumothorax, handful of cases have been reported with its delayed occurrence in the past 5 decades. The purpose of our report is to highlight another uncommon yet interesting case of delayed iatrogenic pneumothorax in an immunocompromised patient after TBB. Although the chain of events behind the pathophysiology of delayed pneumothorax largely remain a mystery, its development has been linked to altered immune mechanics as they are frequently recognized in immunocompromised patients.

Abstract
RATIONALE AND OBJECTIVES To determine the utility of routine postbronchoscopy chest radiography to detect pneumothorax. MATERIALS AND METHODS This retrospective quality improvement cohort study was approved by the Institutional Review Board. All outpatients (n = 1443) who underwent protocol-driven postbronchoscopy chest radiography in one health system from January 2010 to July 2017 were identified by electronic medical record query. The prevalence of pneumothorax (with 95% confidence intervals [CI]) and clinical outcome were determined following coded review of chest radiography reports and review of the electronic medical record. The effect of smoking and lung disease on risk of pneumothorax was determined with Chi Square tests. RESULTS Of 1443 subjects undergoing interventional bronchoscopy, 6% (93/1443) were current smokers, 35% (505/1442) were former smokers, and 35% (540/1443) had known lung disease. Pneumothorax prevalence was 3.4% (49/1443; 95% CI: 2.6%-4.5%) following any intervention and 4.1% (42/1032; 95% CI: 3.9%-5.5%) following transbronchial intervention. In those without known pre-existing pneumothorax or a confirmed false positive diagnosis, the real overall pneumothorax rate was 2.9% (42/1443; 95% CI: 2.1%-3.9%). The risk of pneumothorax did not differ based on smoking history (p = 0.99) or history of lung disease (p = 0.19). Of 49 subjects with pneumothorax, 13 were symptomatic, and 10 had a change in management including chest tube placement (N = 2), inpatient admission (N = 3), and/or observation (N = 7). No pneumothorax-related intervention was performed in asymptomatic patients. CONCLUSION Pneumothorax following interventional outpatient bronchoscopy is uncommon, usually asymptomatic, and often clinically insignificant. Asymptomatic postbronchoscopy patients are very low risk and may not need routine imaging.

Abstract
Objective To identify bronchoscopy-related complications and discomfort, meaningful complication rates, and predictors. Method We conducted a systematic literature search in PubMed on 8 February 2016, using a search strategy including the PICO model, on complications and discomfort related to bronchoscopy and related sampling techniques. Results The search yielded 1,707 hits, of which 45 publications were eligible for full review. Rates of mortality and severe complications were low. Other complications, for instance, hypoxaemia, bleeding, pneumothorax, and fever, were usually not related to patient characteristics or aspects of the procedure, and complication rates showed considerable ranges. Measures of patient discomfort differed considerably, and results were difficult to compare between different study populations. Conclusion More research on safety aspects of bronchoscopy is needed to conclude on complication rates and patient- and procedure-related predictors of complications and discomfort.

Abstract
BACKGROUND Fiberoptic bronchoscopy (FOB) with transbronchial biopsy (TBB) is complicated by a pneumothorax in 1-4% of cases. Performance of routine post-TBB chest radiography (CXR) results in an extremely low diagnostic yield but nevertheless is the common clinical practice prevailing today. It has previously been suggested that routine post-TBB CXR could be avoided in asymptomatic patients. OBJECTIVE The objective of this study was to prospectively assess the feasibility and safety of this approach. METHODS The study group included 201 consecutive patients who underwent FOB with TBB at our institution between January 2009 and September 2014. All subjects completed a preprocedural, a 2-hour postprocedural, and a 24- to 48-hour postprocedural symptom questionnaire (chest pain, dyspnea, and cough). Post-TBB CXR was ordered by the treating physician only if indicated. All cases of pneumothorax were documented. Additionally, the following information was recorded: sex, age, immune status, indication for FOB, total number of biopsies done, lobe sampled, and pulse oxygen saturation. RESULTS Sixteen CXRs were ordered by the treating physician due to suspected pneumothorax (8%). Early-onset pneumothorax (i.e. within 2 h of TBB) was diagnosed radiologically in 6 patients (3%). Two late-onset pneumothoraxes (1%) were diagnosed more than 24 h after TBB. No pneumothoraxes of clinical significance were diagnosed among asymptomatic patients without significant oxygen desaturation events. CONCLUSIONS Among asymptomatic patients without significant desaturation events, pneumothorax is rare and usually of negligible clinical significance. Therefore, performance of routine CXR after TBB is not necessary and can be safely avoided in this category of patients.

Abstract
BACKGROUND Pneumothorax (PTX) following flexible bronchoscopy (FB) and transbronchial lung biopsy (TBLB) occurs in 1% to 6% of cases. Chest radiography (CXR) is therefore routinely requested to detect PTX following TBLB. The objective of this study was to prospectively evaluate the accuracy of ultrasound (US) in the detection of post-TBLB PTX. METHODS Consecutive patients undergoing elective FB at a tertiary care hospital were included in the study. A real-time US was used to rule out PTX immediately after FB. PTX was defined by the absence of lung sliding and the presence of "lung point" and "stratosphere" sign. In cases of PTX, US was repeated at 2-hour intervals, and the resolution or progression of PTX was assessed based on dynamic shifts of the "lung points." RESULTS A total of 379 FB procedures and 113 TBLB were performed during the study period. PTX occurred in 8 (2.1%) patients. US detected all cases of PTX, whereas CXR missed 1 PTX. The sensitivity, specificity, and overall accuracy for US were 100% as compared with sensitivity of 87.5% and accuracy of 99.6% for the CXR group. Shift of the "lung point" below the mid-thoracic line implied the progression of PTX and hence favored intervention (performed in 3 cases), whereas conservative management was done in cases where "lung point" shifted above mid-thoracic line. CONCLUSIONS This study demonstrates a good sensitivity of US in detecting PTX following TBBL. Bedside US may become the method of choice for diagnosing, monitoring, and managing PTX after TBLB.

Abstract
BACKGROUND Diagnostic bronchoscopy has been considered as a safe and effective procedure. Endobronchial ultrasound with a guide sheath (EBUS-GS) for the diagnosis of peripheral pulmonary lesions (PPLs) is becoming a common procedure, but reports about its safety are missing. OBJECTIVES The aim of this study was to evaluate the safety profile of EBUS-GS for the diagnosis of PPLs. METHODS All patients with PPLs who underwent EBUS-GS between September 2012 and August 2014 at the National Cancer Center Hospital were included. Postprocedural complications and the durability of devices were retrospectively reviewed. RESULTS During the study period, EBUS-GS procedures were performed for 965 PPLs. The overall complication rate was 1.3% (13/965): 0.8% (8/965) for pneumothorax and 0.5% (5/965) for pulmonary infection. There was no significant hemorrhage, air embolism, tumor seeding or procedure-related death, and there was no breakage of the guide sheath. Only four radial probes were broken during the study period without any adverse reactions. CONCLUSIONS EBUS-GS is a tolerable procedure, and the devices are durable.

Abstract
BACKGROUND AND STUDY OBJECTIVE Pneumothorax following flexible bronchoscopy (FB) with transbronchial biopsy (TBB) occurs in 1 to 6% of cases. Routine chest radiography (CXR) following TBB is therefore requested by most pulmonologists in an attempt to detect complications, particularly pneumothorax. The objective of this study was to determine if routine CXR after bronchoscopy and TBB is necessary. PATIENTS AND METHOD The study group included 350 consecutive patients who underwent FB with TBB at our institution between December 2001 and January 2004. Routine CXR was performed up to 2 h after the procedure in all cases. Additionally, the following information was recorded in all patients: sex, age, immune status, indication for bronchoscopy, total number of biopsies done, segment sampled, pulse oxygen saturation, and development of symptoms suggestive of pneumothorax. RESULTS Pneumothorax was diagnosed radiologically in 10 patients (2.9%). Seven patients had symptoms strongly suggestive of pneumothorax prior to CXR, including four patients with large (> 10%) pneumothorax. The other three patients were asymptomatic, with only minimal pneumothorax (</= 10%), which resolved completely 24 to 48 h later. CONCLUSIONS We conclude that routine CXR after bronchoscopy with TBB is necessary only in patients with symptoms suggestive of pneumothorax. In asymptomatic patients, pneumothorax is rare and usually small, so routine CXR is not necessary in this category of patients.

Abstract
STUDY OBJECTIVE To evaluate the clinical significance and cost effectiveness of routine chest radiographs in the postanesthesia care unit (PACU). DESIGN Prospective study. SETTING University hospital. PATIENTS 100 patients who were admitted to the PACU following various surgical procedures, and in whom a postoperative chest radiograph was routinely performed. INTERVENTIONS Chest radiograph was taken in each study patient soon after admission to the PACU. The indications for postoperative chest radiograph were: thoracotomy (30 patients), thoracoscopy (7), central vein catheterization (CVC) (75), pulmonary artery catheterization (3), and mechanical ventilation (36). A staff anesthesiologist examined each patient, evaluated each chest radiograph, and decided if a treatment action was to be taken. A chest radiologist later evaluated each chest radiograph, and her interpretation was compared with the anesthesiologist's interpretation to assess if this may affect patient management. MEASUREMENTS AND MAIN RESULTS The anesthesiologist found eight abnormal chest radiographs (8%): three with pulmonary congestion, four in whom the CVC was in the right atrium, and one with malpositioned CVC. In four patients (4%), the chest radiographic findings directly affected patient management. The radiologist confirmed the anesthesiologist's interpretation and found four additional abnormalities: one pulmonary congestion, one malpositioned CVC, and two chest radiographs, each with a small pneumothorax. CONCLUSIONS Abnormal chest radiographic findings resulted in a change in the management of only 4% of the patients. Therefore, the yield of a routine postoperative chest radiograph in the PACU is low. Performing a chest radiograph for a specific indication rather than on a routine basis, may decrease work load and save expenses. Postoperative chest radiography can be safely evaluated by a staff anesthesiologist.

Abstract
The objective of our study was to determine the safety of transbronchial biopsy (TBB) in nonhospitalized patients. The design was a prospective study of the consecutive cases from July 1987 until September 1988 in the setting of a university hospital of the third level with 1,800 beds. The patients were a consecutive sample of 169 patients who had 184 procedures of fiberoptic bronchoscopy (FOB) with TBB performed. They suffered from different diseases: lung nodules or masses, diffuse interstitial disease, alveolar condensation, etc. An FOB with TBB was performed in immunocompetent outpatients, who were kept under observation for four hours and then had a chest roentgenogram taken afterwards. We contacted them again after 72 hours to rule out delayed complications. In three cases, more than 100 ml of blood were obtained during the FOB, without significant hemoptysis being recorded in those patients during the observation period; chest pain occurred in 15 patients during the TBB; pneumothorax occurred in two patients (1 percent), one of whom required admission to the hospital, without requiring chest tube drainage. Other complications are reported (bronchospasm, parenchymal hemorrhage, and pneumonia). In conclusion, we consider the TBB to be a technique with a low incidence of complications for outpatients, so therefore we do not believe that admission to the hospital is mandatory for this type of patient, although we do recommend a longer observation period.

Abstract
The objective of this study was to determine if flexible FOB could be performed safely without premedication other than topical anesthesia. A total of 281 procedures performed during a 12-month period at a VA medical center were reviewed. Ninety-one procedures performed without premedication were compared with 190 procedures performed with premedication. Complications occurred in 5 percent of patients in each group. Statistical analysis revealed no significant differences in age, spirometry, P(A-a)O2 or SaO2 between both groups. Despite the proven safety of outpatient FOB without sedation, many bronchoscopists administer complicated premedication regimens and employ ambulatory surgery beds or recovery rooms to monitor patients before and after procedures. These results support a simplified approach to routine FOB which would include no premedications and greater use of outpatient facilities resulting in decreased expenditures without compromising patient care, safety or comfort.
