Application of Electromagnetic Navigation Bronchoscopy in the early diagnosis and treatment of lung cancer: a narrative review

The diagnosis of lung cancer has long been a problem facing clinicians worldwide, and the emergence of electromagnetic navigation bronchoscopy (ENB) has played a critical role in the early diagnosis of lung cancer. Compared with other types of biopsy techniques (e.g., transthoracic needle biopsy, bronchoscopy, thoracoscopic biopsy, and thoracotomy), ENB guarantees high diagnostic accuracy and safety. In recent years, with the continuous development of ENB technology, the scope of its epitaxy has also expanded. This technology is no longer a simple auxiliary diagnosis test but an innovative technology that simultaneously assists in surgical treatment, opening new avenues of research for the treatment of early-stage lung cancer. However, ENB, as a human-mediated operating system, has some limitations and uncertainties in its actual clinical application and promotion, which need to be addressed as we continue to develop ENB technology. In response to the bottleneck in developing ENB technology in current clinical diagnosis and treatment, relevant scientific research and development personnel and clinicians have also performed continuing exploration and improvement of methods. However, to completely overcome the limitations of ENB, more technological innovations are needed. In this review, we describe the current major clinical application directions, application advantages, and limitations of ENB.
