Description of Event or Problem

OLYMPUS REVIEWED A LITERATURE TITLED "COMPUTED TOMOGRAPHY BRONCHUS SIGN SUBCLASSIFICATION DURING RADIAL ENDOBRONCHIAL ULTRASOUND-GUIDED TRANSBRONCHIAL BIOPSY: A RETROSPECTIVE ANALYSIS." THIS WAS A RETROSPECTIVE STUDY OF CONSECUTIVE PATIENTS WHO UNDERWENT RADIAL ENDOBRONCHIAL ULTRASOUND TRANSBRONCHIAL BIOPSY (REBUS-TBB) FOR PERIPHERAL PULMONARY LESIONS BETWEEN NOVEMBER 2015 AND OCTOBER 2017. PATIENTS WITH CENTRAL PULMONARY LESIONS (PPLS) WITH EVIDENCE OF ENDOBRONCHIAL INVOLVEMENT, THOSE WHO UNDERWENT RE-EXAMINATION FOR THE SAME LESION, THOSE WITH UNKNOWN FINAL DIAGNOSIS DUE TO LOSS AT FOLLOW-UP, AND THOSE WITH LACK OF EVALUATION BY HIGH RESOLUTION CT (HRCT) IMAGING OF LESIONS THAT WERE LESS THAN 1MM IN THICKNESS WERE EXCLUDED. THE STUDY CONCLUDES THAT CT BRONCHUS SIGN SUBCLASSIFICATION MAY PROVIDE USEFUL INFORMATION TO FACILITATE THE SELECTION OF BRONCHOSCOPIC TECHNIQUES FOR ACCURATE DIAGNOSIS OF PPLS. REBUS-TBB GENERALLY HAD AN ACCEPTABLE DIAGNOSTIC PERFORMANCE IN CT-BS GROUP I. HOWEVER, TYPE IC IS EXCEPTIONAL, AND IT MAY BE USEFUL TO OBTAIN LARGER SAMPLES WITH A 1.9 MM FORCEPS (OR CONSIDER CRYOPROBES). REBUS-TBB IS NOT EXPECTED TO PROVIDE SUFFICIENT DIAGNOSTIC PERFORMANCE IN CT-BS GROUP II; THEREFORE, NEWER GUIDED BRONCHOSCOPIC TECHNIQUES APPROPRIATE FOR EACH BRONCHUS TYPE SHOULD BE CONSIDERED. OVERALL, 9 PATIENTS PRESENTED WITH PNEUMOTHORAX, AMONG WHOM FIVE REQUIRED CHEST TUBE DRAINAGE AND TWENTY-EIGHT DEVELOPED PULMONARY INFECTION. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS PNEUMOTHORAX - 9 PATIENTS PULMONARY INFECTION - 28 PATIENTS.
