Abstract Background Patients with an anterior mediastinal mass are at risk of perioperative respiratory collapse. Case presentation A 74-year-old woman with a large anterior mediastinal mass that led to partial tracheal collapse (shortest diameter, 1.3 mm) was scheduled for tracheobronchial balloon dilation and stent placement under general anesthesia. Although veno-venous extracorporeal membrane oxygenation (V-V ECMO) had been established, maximum flow was limited to 1.6 L/min, and general anesthesia induction was followed by hypoxia probably due to inadequate ventilation. A flexible bronchoscope was inserted through the tracheal lumen that was being compressed by the anterior mass; this not only increased tracheal patency but also enabled positive pressure ventilation and resulted in recovery from hypoxia. Scheduled procedures were successfully performed without complications. Conclusion We describe a case wherein tracheal patency was transiently maintained by inserting a flexible bronchoscope in a patient with an anterior mediastinal mass.

Abstract Background It is uncommon for a bronchial stump-related complication to develop during the remote postoperative period in a case of obstructive pneumonia owing to migration of the suture material. Here, we describe a case of bronchial obstructive pneumonia that developed owing to migration of the suture material in the airway 8 years after pulmonary resection. Case presentation A 34-year-old woman underwent left lower lobectomy for a pulmonary carcinoid tumor (pT1bN0M0-stage IA) in 2010. She experienced obstructive pneumonia, and chest computed tomography revealed a mass protruding from the bronchial stump to the bronchial lumen in 2018. After treatment for pneumonia, flexible bronchoscopy showed the presence of a fibrous suture material (Teflon pledget) completely obstructing the left second carina. A week later, the Teflon pledget obstructing the bronchial lumen was removed using a flexible bronchoscope with the patient under general anesthesia. The procedure was completed without removing the small amount of granulation tissue because the bronchial lumen opened after removing the Teflon pledget. She has remained asymptomatic for 1 year after removal. Conclusions In this case, the complication of obstructive pneumonia developed owing to migration of the non-absorbable suture materials used to suture the bronchial stump. Bronchoscopic management of this rare complication comprised endobronchial removal with the patient under general anesthesia. Given our experience with this case, we believe that such conservative management should allow for excellent results in most instances and avoid the need for reoperation.

Abstract Background The microbiota of the lower respiratory tract in patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD) has not been fully evaluated. We explored the role of the lung microbiota in NTM-PD by analyzing protected specimen brushing (PSB) and bronchial washing samples from patients with NTM-PD obtained using a flexible bronchoscope. Results Bronchial washing and PSB samples from the NTM-PD group tended to have fewer OTUs and lower Chao1 richness values compared with those from the control group. In both bronchial washing and PSB samples, beta diversity was significantly lower in the NTM-PD group than in the control group (P = 2.25E-6 and P = 4.13E-4, respectively). Principal component analysis showed that the PSBs and bronchial washings exhibited similar patterns within each group but differed between the two groups. The volcano plots indicated differences in several phyla and genera between the two groups. Conclusions The lower respiratory tract of patients with NTM-PD has a unique microbiota distribution that is low in richness/diversity.

Extracorporeal membrane oxygenation (ECMO) is helpful in providing ventilatory support when other conventional methods of ventilation fail. We report a case of successful management of advanced tracheal malignancy with impeding airway obstruction where veno-venous ECMO (VV-ECMO) was instituted prior to performing critical endotracheal procedure. After securing the VV-ECMO through right jugular vein and left femoral vein under local anaesthesia, the tracheal stent placement was conducted under flexible bronchoscope and fluoroscope control. Oxygenation and carbon dioxide levels were maintained by the ECMO. VV-ECMO is a useful adjunct in the management of subglottic difficult airway obstruction due to complex tracheal pathology where conventional ventilation may not be possible or adequate.

Steerable Needle

Abstract Bronchoscopic diagnosis and intervention in the lung is a new frontier for steerable needles, where they have the potential to enable minimally invasive, accurate access to small nodules that cannot be reliably accessed today. However, the curved, flexible bronchoscope requires a much longer needle than prior work has considered, with complex interactions between the needle and bronchoscope channel, introducing new challenges in steerable needle control. In particular, friction between the working channel and needle causes torsional windup along the bronchoscope, the effects of which cannot be directly measured at the tip of thin needles embedded with 5 degree-of-freedom magnetic tracking coils. To compensate for these effects, we propose a new torsional deadband-aware Extended Kalman Filter to estimate the full needle tip pose including the axial angle, which defines its steering direction. We use the Kalman Filter estimates with an established sliding mode controller to steer along desired trajectories in lung tissue. We demonstrate that this simple torsional deadband model is sufficient to account for the complex interactions between the needle and endoscope channel for control purposes. We measure mean final targeting error of 1.36 mm in phantom tissue and 1.84 mm in ex-vivo porcine lung, with mean trajectory following error of 1.28 mm and 1.10 mm, respectively.

Introduction: In many pulmonary diseases, despite radiological & clinical investigations, laboratory tests and function studies, the diagnosis becomes difficult. Bronchoalveolar Lavage (BAL) is a minimally invasive method in which cells are collected from bronchial and alveolar spaces for cytology. This is facilitated by using a flexible bronchoscope with which a biopsy is taken following BAL. Bronchoscopy with BAL when used appropriately can offer correct diagnosis which in turn aids in proper management of the patient. Aim: To find the concordance of BAL findings with the histopathological features of Transbronchial Lung Biopsy (TBLB) in non-neoplastic lung diseases. Materials and Methods: It was a retrospective study conducted in Kempegowda Institute of Medical Sciences, Bengaluru, Karnataka. A total of 40 patients presenting with clinico-radiological findings, suggesting a non-neoplastic lung disease in the year 2019, undergoing bronchoscopy with BAL and concurrent TBLB were chosen. The BAL fluid was processed and differential count of cells was done to classify according to the American Thoracic Society Guidelines. Concordance was checked between the diagnoses made on TBLB and BAL analysis. Results: In the present study, a total of 40 cases were included of which 13 (32.5%) cases showed neutrophilic, 16 (40%) cases showed lymphocytic, 5 (12.5%) cases showed eosinophilic and 6 (15%) cases showed normal cellular distribution on BAL cytology. Diagnoses on studying TBLB included nine cases of Nonspecific Interstitial Pneumonia, seven cases of Usual Interstitial Pneumonia, six cases of Bronchiolitis Obliterans Organising Pneumonia, three cases of Bronchiolitis, two cases each of pulmonary tuberculosis and granulomatous inflammation. There was one case each of actinomycosis, sarcoidosis, lung abscess and mucor mycosis. Normal histology was noted in seven cases. The sensitivity of BAL fluid analysis was found to be 84.84% and the concordance was 80%. The Kappa value obtained was 0.71 indicating good agreement/concordance between BAL cytology and TBLB. Conclusion: The data from the current study suggest that differential cell counts in BAL provide diagnostic information of fundamental importance in frequently occurring non-neoplastic lung diseases in the community.
