          Abstract

          Recent advances in bronchoscopy, such as transbronchial biopsy (TBB) using endobronchial ultrasonography with a guide sheath (EBUS-GS), have improved the diagnostic yield of small-sized peripheral lung lesions. In some cases, however, it is difficult to obtain adequate biopsy samples for pathological diagnosis. Adequate prediction of the diagnostic accuracy of TBB with EBUS-GS is important before deciding whether bronchoscopy should be performed.

          CT-guided needle biopsy of lung lesions: a survey of severe complication based on 9783 biopsies in Japan.

          Kiyoshi Mori, Yasuo Nakajima, Shuji Adachi … (2006)
          The aim of our study was to update the rate of severe complications following CT-guided needle biopsy in Japan via a mailed survey. Postal questionnaires regarding CT-guided needle biopsy were sent out to multiple hospitals in Japan. The questions regarded: the total number and duration of CT-guided lung biopsies performed at each hospital, and the complication rates and numbers of pneumothorax, hemothorax, air embolism, tumor seeding, tension pneumothorax and other rare complications. Each severe complication was followed with additional questions. Data from 9783 biopsies was collected from 124 centers. Pneumothorax was the most common complication, and occurred in 2412 (35%) of 6881 cases. A total of 39 (35%) hospitals reported 74 (0.75%) cases with severe complications. There were six cases (0.061%) with air embolism, six cases (0.061%) with tumor seeding at the site of the biopsy route, 10 cases (0.10%) with tension pneumothorax, six cases (0.061%) with severe pulmonary hemorrhage or hemoptysis, nine cases (0.092%) with hemothorax, and 27 cases (0.26%) with others, including heart arrest, shock, and respiratory arrest. From a total of 62 patients with severe complications, 54 patients (0.55%) recovered without sequela, however one patient (0.01%) recovered with hemiplegia due to cerebral infarction, and the remaining seven patients (0.07%) died. This is the first national study documenting severe complications with respect to CT-guided needle biopsy in Japan. The complication rate in Japan is comparable to internationally published figures. We believe this data will improve both clinicians as well as patients understanding of the risk versus benefit of CT-guided needle biopsy, resulting better decisions.

            Rapid on-site cytologic evaluation during endobronchial ultrasound-guided transbronchial needle aspiration for diagnosing lung cancer: a randomized study.

            Masahiko Ando, N Murata, Hideo Saka … (2012)
            Although rapid on-site cytologic evaluation (ROSE) is widely used during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), its role remains unclear. The purpose of the present study was to evaluate the efficacy of ROSE during EBUS-TBNA in the diagnosis of lung cancer. One hundred and twenty patients highly suspected of having lung cancer who had hilar/mediastinal lymphadenopathy or a tumor adjacent to the central airway were enrolled in this study and randomized to undergo EBUS-TBNA with or without ROSE. Twelve patients with visible endobronchial lesions were excluded in the analysis. Thus, a total of 108 patients (55 in the ROSE group, 53 in the non-ROSE group) were analyzed. Additional procedures including EBUS-TBNA for lesions other than the main target lesion and/or transbronchial biopsy in the same setting were performed in 11% of patients in the ROSE group and 57% in the non-ROSE group (p < 0.001). Mean puncture number was significantly lower in the ROSE group (2.2 vs. 3.1 punctures, p < 0.001), and mean bronchoscopy time was similar between both groups (22.3 vs. 22.1 min, p = 0.95). The sensitivity and accuracy for diagnosing lung cancer were 88 and 89% in the ROSE group, and 86 and 89% in the non-ROSE group, respectively. No complications were associated with the procedures. ROSE during EBUS-TBNA is associated with a significantly lower need for additional bronchoscopic procedures and puncture number. Copyright © 2013 S. Karger AG, Basel.

              Diagnostic yield of combined bronchoscopy and endobronchial ultrasonography, under LungPoint guidance for small peripheral pulmonary lesions.

              Motohiro Tamiya, Norio Okamoto, Shinji Sasada … (2013)
              The yield of biopsy performed during bronchoscopy is reduced if the lesion is smaller than 30 mm. We evaluated the performance of a new diagnostic technique combining endobronchial ultrasonography with a guide sheath (EBUS-GS) and a virtual bronchoscopic navigation system, LungPoint (Broncus Technologies, Inc., Mountain View, CA, USA), for the diagnosis of small (≤30 mm) peripheral pulmonary lesions (PPL).
