Tunneled Pleural Catheters: An Effective Nonsurgical Alternative for Nonexpandable Lung in Chronic Pleural Infection.

BACKGROUND

Open window thoracostomy (OTW) is the standard of care for debilitated patients with chronic pleural infection and nonexpandable lungs (NEL) who are not candidates for major surgical intervention. Tunneled pleural catheters (TPC) offer tremendous treatment potential in this setting based on their efficacy in malignant pleural effusion and NEL. We aim to assess the efficacy, safety, and health care utilization of TPC in this setting.

METHODS

We retrospectively evaluated patients who underwent TPC procedures for the long-term management of chronic pleural infection and NEL who were not candidates for major surgical intervention. Clinically, complete treatment success was defined as fever abatement, normalization of white cell count, and stoppage of antimicrobial therapy without requiring surgical intervention. It is deemed a partial success if chronic antimicrobial suppression is still needed.

RESULTS

There were 20 patients who had TPC placed for chronic pleural infection with NEL. Clinical and partial treatment success was achieved in 9/17 and 8/17 patients, respectively, excluding 3 patients who were placed on comfort measures only. The median change in pleural volume was -218 mL. The median length of stay after TPC placement was 4.5 days. TPC was removed in 8 patients due to successful obliteration of pleural space in a median duration of 46.5 days. Four patients passed away with TPCs in place, 7 retained TPCs at the last health care system contact, and 1 patient had OTW due to TPC failure.

CONCLUSION

This exploratory study suggests that TPC is an effective and safe intervention for the management of patients with chronic pleural infection and NEL lung who are not candidates for surgical intervention.
