Pneumothorax Safety of Pleural-Depth-Trimmed Hookwires for Lung Nodule Localization

Taiwan1,072 participantsStarted 2015-09-01

Plain-language summary

The goal of this observational study is to learn about the pneumothorax risk associated with the Pleural-Depth-Trimmed Hookwire (PDTH) technique in patients undergoing Preoperative CT-Guided Lung Nodule Localization (POCTGL). The main question it aims to answer is: Does the specialized PDTH technique increase the risk of iatrogenic pneumothorax compared to dye-only localization in a setting utilizing advanced puncture guidance?. Participants were a retrospective cohort of patients who underwent POCTGL procedures between 2015 and 2022, and their procedural data and post-procedural complications were analyzed.

Inclusion Criteria: * Consecutive series of patients who underwent Preoperative Computed Tomography-Guided Lung Nodule Localization (POCTGL) at our medical center between September 2015 and January 2022. * All included procedures were performed in patients who subsequently underwent Video-Assisted Thoracoscopic Surgery (VATS) lung resection on the same day. Exclusion Criteria For the primary Generalized Estimating Equations (GEE) analysis: * Nodules localized after a pneumothorax event occurred (n=59) were excluded. Exclusion Criteria For the Propensity Score Matching (PSM) analysis: * Nodules localized after a pneumothorax event (n=59). * Nodules that were not the first localized nodule during the POCTGL procedure (n=495). * Nodules associated with a previous ipsilateral VATS (n=16).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
