Abstract





Background. Transbronchial lung cryobiopsy (TBLC) is a relatively new technique recommended for sampling of lung parenchyma in patients with suspected interstitial lung disease (ILD) and as an alternative to surgical lung biopsy. A more recently introduced technique is endobronchial ultrasound-guided transbronchial mediastinal lymph node lymph node cryobiopsy (EBUS-TMC) to enable tissue biopsy of mediastinal lymph nodes. However, there are no data on the feasibility of implementing these techniques in a resource-limited African setting, where there is a chronic bed shortage and same-day discharges are preferable.


Objectives. To determine the feasibility and diagnostic yield of TBLC and EBUS-TMC in a resource-limited African setting.


Methods. We performed an audit of lung and lymph node cryobiopsy procedures performed at the E16 Respiratory Clinic at Groote Schuur Hospital, Cape Town, South Africa. Indications, diagnostic performance outcomes and lessons learned were documented and analysed.


Results. Sixteen patients underwent 19 cryobiopsy procedures that were performed under general anaesthesia (n=11 TBLC, n=8 EBUS- TMC, including 3 patients in whom both TBLC and EBUS-TMC were concurrently performed). The main indications were evaluation of ILD and suspected lymph node malignancy. The diagnostic yield was 63.6% for TBLC (n=7/11; 2 nonspecific interstitial pneumonia, 2 sarcoidosis, 1 espiratory bronchiolitis-ILD, 1 organising pneumonia, 1 nonspecific chronic inflammation) and 50.0% for EBUS-TMC (n=4/8; 1 plasmacytoma, 1 lymphoma, 1 cryptococcus infection, 1 patient with both cryptococcus infection and tuberculosis). Of the patients, 2 had moderate bleeding and 3 had mild bleeding, and 14 were discharged on the day of the procedure.


Conclusion. TBLC and EBUS-TMC, with avoidance of surgical lung biopsy in most patients and same-day discharge in most patients, are feasible in an African setting. These data inform clinical practice and programme implementation in resource-limited settings.
