Objectives: The main drawback of the hook-wire technique for locating ground glass nodules before video assisted thoracoscopic surgery (VATS) resection is the risk of the hook dislodging during single lung ventilation as the lung collapses. In order to reduce the friction of the thread in the wall, the investigators modified the technique by first positioning a catheter in the chest wall and introducing the carrying needle through the catheter. The objective was to evaluate the success rate and complications of this technique.

Material and Methods : the investigators retrospectively included all patients undergoing VATS resection of solitary lung nodules after localization using the sliding wire technique.

Inclusion Criteria

- All patients who underwent VATS for pulmonary nodule resection in the thoracic surgery department of Nice University hospital after pre-operative hook-wire insertion using the sliding-wire technique

Exclusion criteria: None

Patients of the university hospital of Nice, France
