Abstract

Abstract : Purpose of review: Over the last decades, in addition to the traditional fluoroscopy, various and innovative guidance systems have been adopted in clinical practice for transbronchial approach to peripheral pulmonary lesions (PPLs). The aim of this article is to summarize the most recent data on available guidance systems and sampling tools, evaluating also advantages and limitations of each technique. Recent findings: Although several studies have been published over the last years, large randomized studies comparing the different techniques are scanty. Fluoroscopy is the traditional and still most widely utilized guidance system. New guidance systems (electromagnetic navigation bronchoscopy, ultrasound miniprobe, cone beam computed tomography) seems to provide a better sensitivity, especially for small lesions not visualized by fluoroscopy. Among the sampling instruments, there is a good evidence that flexible transbronchial needle provides the better diagnostic yield and that sensitivity may increase if more than one sampling instrument is used. Summary: Even if great progress has been done since the first articles on the transbronchial approach to PPLs, better scientific evidence and more reliable randomized trials are needed to guide interventional pulmonologists in choosing the best technique according to different clinical scenarios and source availability.
