Erratum

In the article titled “Role of antifibrotic drugs in the management of post-COVID-19 interstitial lung disease: A review of literature and report from an expert working group”, published on pages 177-186, Issue 2, Volume 39 of Lung India[], the third author’s name is incorrectly written as “Sahajal Dhoori.” The correct author’s name should read as “Sahajal Dhooria.”

The “How to cite this article” section should read correctly as ”Salvi SS, Ghorpade D, Dhooria S, Dhar R, Dumra H, Chhajed PN, et al.

Sir,

We have previously described a barrier enclosure device use to limit aerosol dispersion during high aerosol-generating procedures such as flexible bronchoscopy and endotracheal intubation to protect health-care workers.[12] While using the barrier enclosure device, one may occasionally encounter difficulty in sampling lesions located either distally or in the upper lobes posterior segment. Furthermore, there is a restriction of hand movements due to the enclosure device.[34] Herein, we describe an instance where we encountered difficulty in accessing a lesion located posterior to the trachea.

A 62-year-old lady presented with cough and fever for 2 months. She was diagnosed with renal cell carcinoma (RCC) 2 years back and was treated with nephrectomy followed by chemotherapy. On evaluation, the computed tomography of the thorax revealed a heterogenous retro tracheal mass [Figure 1, panel A]. We considered recurrence of RCC versus other causes (tuberculosis, lung carcinoma) and performed endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA). Such posteriorly located lesions can be accessed with EBUS by changing the position of the bronchoscopist to the side of patient and directing the EBUS scope to face posteriorly. However, the barrier enclosure device precluded the access at this location. We performed the EBUS TBNA using the side oblong ports in the barrier enclosure device. The patient was initially intubated with the EBUS scope using the main port at the head end of the patient. Subsequently, the operator stood to the right side of the patient. The EBUS scope was manipulated and directed posteriorly using the oblong aperture on the right side of the barrier device to localize the lesion. Once the lesion was located with EBUS, the needle was inserted into the lesion with the operator remaining in the same position. We completed the procedure without any complications. Our experience suggests that barrier enclosure devices (with suitable modifications) can be used to perform EBUS at difficult target locations without compromising on the safety of health-care workers during the pandemic.
