Аннотация
BACKGROUND: Transbronchial lung cryobiopsy (TBLC) is useful for diagnosing diffuse parenchymal lung diseases (DPLD). To prevent bleeding during TBLC, the balloon occlusion method has been recommended. However, displacement can occur occasionally, especially with a 4-Fr balloon. We aimed to investigate whether the use of a 6-Fr balloon would allow tamponade at a more proximal position and decrease balloon displacement in TBLC under flexible bronchoscopy.
METHODS: We retrospectively reviewed 20 patients with DPLD who underwent TBLC using the modified balloon occlusion method between June 2019 and May 2021.
RESULTS: The median number of TBLCs was three (range, 2-5). The most common balloon placement site was the right basal bronchus (14 patients). Mild and moderate bleeding was seen in 10 patients each. Successful balloon occlusion was achieved in all patients without dislocation.
CONCLUSION: The modified balloon occlusion method in TBLC under flexible bronchoscopy might be a reasonable option for bleeding prevention.
