Central or Proximal Lung Abscess After Endoscopic Catheter Drainage Has Not Resolved
Clinical Scenario
This protocol applies to a lung abscess located centrally or proximally — not a peripheral lesion — where a bronchial airway communicates with the abscess cavity (bronchial sign). The presence of a bronchial airway connection is the key anatomical feature that distinguishes this group and determines which drainage approach is appropriate.
Previous Step Did Not Achieve the Expected Goal
Endoscopic catheter drainage (ECD) was the indicated prior step for this anatomical configuration. ECD involves flexible bronchoscopic placement of a pigtail catheter into the abscess cavity via the communicating airway, with aspiration, lavage, and continuing drainage. The goal of ECD is clinical and radiological evidence of improvement, with resolution of the abscess. When that resolution has not been achieved, this protocol defines the structured next step.
Next-Step Approach (Partial Overview)
For patients who have not responded to the drainage-based approach, a surgical intervention targeting the involved lung tissue is indicated. The extent of resection is tailored to the individual case.
The complete structured regimen — including patient selection criteria, procedural detail, and goals — is available in the full protocol.
Treatment Goals
The clinical targets are improvement of symptoms and signs of infection, and improvement of radiographic findings.

- ECD can be done for central and proximally located abscesses.
- The primary factor in choosing ECD over PTTD is the location of the abscess, and the presence of a bronchial airway leading to the abscess for successful ECD.
- Surgery is indicated in patients who fail to improve after receiving an adequate course of antibiotics either alone or in combination with percutaneous catheters or endoscopic drainage.
- Surgical management ranges from wedge resection to lobectomy or even pneumonectomy.
- The response may be monitored by observing improvement of symptoms and signs of infection, and improvement of radiographic findings.
