Background: The widespread use of chest CT has increased the number of detected pulmonary nodules. Nodules with intermediate risk of malignancy warrant further evaluation with PET-CT or sampling. Although sampling with conventional bronchoscopy presents lower complication rates compared to transthoracic needle biopsy (TTNB), it is limited by the inability to reach distal airways. To overcome this shortcoming, a new bronchoscopic technique named robotic bronchoscopy (RB) has emerged.
Methods: A literature review was used to clarify the rationale behind RB emergence, describe RB procedure, and summarize data regarding its efficacy and safety.
Results: The FDA has approved three RB platforms for clinical use. RB is safe, presenting a mortality and complication rate of 0% and 0-8.1%, respectively. Common complications include pneumothorax (0-5.7%) and minor bleeding (0-3.2%). However, its diagnostic yield remains lower than that of TTNB.
Conclusions: RB is a promising bronchoscopic technique that aims to overcome the limitations of conventional bronchoscopy and improve upon the current techniques of guided bronchoscopy for the investigation of pulmonary nodules. Despite the lower complication rate, current evidence suggests a lower diagnostic yield compared to TTNB. Additional studies are required to adequately evaluate the role of RB in the diagnosis of pulmonary nodules.

Background: Accurate preoperative positioning is the key to the success of thoracoscopic surgery for small pulmonary nodules. There are many methods for locating pulmonary nodules in clinical practice, but there are currently few research reports on the value of medical adhesive localization.
Objective: To compare the clinical value of two positioning methods, medical adhesive and metal spring coil, in the preoperative application of VATS through retrospective analysis.
Background: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare interstitial lung disease primarily affecting young to middle-aged smokers. While traditionally linked to tobacco use, there is growing evidence that cannabis use may contribute to PLCH.
Methods: We present a case of a 52-year-old male with PLCH associated with heavy cannabis use.
One-stage versus two-stage video-assisted thoracic surgery for synchronous bilateral pulmonary nodules: protocol for a single center, non-randomized clinical trial (OTVATS-1).

Department of General Thoracic Surgery, China-Japan Friendship Hospital, Beijing, China.
Background: Previous retrospective studies demonstrated both one-stage and two-stage video-assisted thoracic surgery (VATS) for bilateral pulmonary nodules were safe and feasible in selected patients. However, prospective data is still lacking. The purpose of this trial is to prospectively compare the prognostic and perioperative outcomes between one-stage and two-stage VATS for synchronous bilateral pulmonary nodules.

The widespread adoption of high-resolution computed tomography (CT) screening has led to increased detection of small pulmonary nodules, necessitating accurate localization techniques for surgical resection. This review examines the evolution, efficacy, and safety of various localization methods for small pulmonary nodules. Studies focusing on localization techniques for pulmonary nodules ≤30 mm in diameter were included, with emphasis on technical success rates and complication profiles.

Non-invasive assessment of pulmonary nodule malignancy remains a critical challenge in lung cancer diagnosis. Traditional methods often lack precision in differentiating benign from malignant nodules, particularly in the early stages. This study introduces an approach using multifractal spectrum analysis to quantitatively evaluate pulmonary nodule characteristics.
