Background. The treatment of lung abscess and infectious pulmonary bullae usually requires long-term antibiotic therapy, mainly due to the lack of a safe and easy drainage technique. Transbronchial drainage using the endobronchial ultrasonography and guide sheath (EBUS-GS) technique may be useful for the drainage of infectious lesions in the lung. Methods. We retrospectively analyzed data from the medical records of patients with lung abscess or infectious pulmonary bullae treated with transbronchial drainage using the EBUS-GS technique. Results. Between September 2016 and February 2020, we found seven cases, including four cases of lung abscess and three of infectious pulmonary bulla. In six of the cases, a guide sheath was inserted into the infectious lesion, and transbronchial drainage was performed successfully. The amount of drained pus was 5-50 ml. The infectious lesions reduced rapidly after drainage. In two of the six cases, anaerobic bacteria were detected in the pus culture. Conclusion. Transbronchial drainage by EBUS-GS may be useful for the treatment and detection of pathogens in lung abscesses and infectious pulmonary bullae.
