Background:
Malignant and nonmalignant pleural effusions (NMPEs) such as those due to hepatic hydrothorax have been successfully treated with an indwelling pleural catheter (IPC) with a low complication rate. There is no literature on the utility or safety of this treatment modality for NMPE post lung resection. We aimed to assess the utility of IPC for recurrent symptomatic NMPE secondary to post lung resection in lung cancer patients over a period of 4 years.
Methods:
Patients who underwent lobectomy or segmentectomy as part of the treatment plan for lung cancer between January 2019 and June 2022 were identified, these patients were screened for post-surgical pleural effusion. A total of 422 underwent lung resection, of which 12 had recurrent symptomatic pleural effusions requiring IPC placement and were selected for final analysis. The primary end points were improved symptomatology and successful pleurodesis.
Results:
Mean time to IPC placement was 78.4 days post-surgery. The mean length of IPC catheter was 77.7 days standard deviation (SD) 23.8. All 12 patients achieved spontaneous pleurodesis (SP), there was no second pleural intervention or re-accumulation of fluid on follow up imaging in any of the subjects after IPC removal. Two patients (16.7%) had skin infection related to catheter placement that was managed with oral antibiotics, there were no cases of pleural infections that required catheter removal.
Conclusions:
IPC is a safe and effective alternative in managing recurrent NMPE post lung cancer surgery with high rate of pleurodesis and acceptable complication rates.
Insights
Indwelling pleural catheters (IPCs) effectively manage recurrent nonmalignant pleural effusions after lung cancer surgery. This safe treatment offers a high rate of spontaneous pleurodesis with manageable complications.
Area of Science:
- Thoracic Surgery
- Pulmonology
- Oncology
Background:
- Nonmalignant pleural effusions (NMPEs) are common after lung resection.
- Limited data exists on indwelling pleural catheter (IPC) use for NMPEs post-lung resection.
- Hepatic hydrothorax is a known NMPE treated with IPCs.
Purpose of the Study:
- To evaluate the safety and efficacy of IPCs for recurrent symptomatic NMPEs in lung cancer patients post-surgery.
- To assess the rate of pleurodesis and complication rates associated with IPC use in this population.
Main Methods:
- Retrospective analysis of lung cancer patients undergoing lobectomy or segmentectomy from January 2019 to June 2022.
- 12 patients with recurrent symptomatic pleural effusions requiring IPC placement were included.
- Primary endpoints: improved symptomatology and successful pleurodesis.
Main Results:
- Mean time to IPC placement was 78.4 days post-surgery.
- All 12 patients achieved spontaneous pleurodesis (SP) without re-accumulation of fluid.
- Two patients (16.7%) experienced manageable skin infections; no pleural infections occurred.
Conclusions:
- IPCs are a safe and effective treatment for recurrent NMPEs following lung cancer surgery.
- High rates of pleurodesis and acceptable complication profiles were observed.
- IPC offers a viable alternative for managing post-surgical pleural effusions.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
Clinical Manifestations:

Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
