    Description of Event or Problem · 0

    OLYMPUS MEDICAL SYSTEMS CORP. (OMSC) RECEIVED A LITERATURE TITLED "ENDOBRONCHIAL ULTRASOUND-GUIDED MEDIASTINAL LYMPH NODAL CRYOBIOPSY IN PATIENTS WITH NONDIAGNOSTIC/INADEQUATE RAPID ON-SITE EVALUATION A NEW STEP IN THE DIAGNOSTIC ALGORITHM."    LITERATURE SUMMARY THIS PROSPECTIVE STUDY AIMED TO EVALUATE THE DIAGNOSTIC YIELD OF EBUS-GUIDED MEDIASTINAL CRYOBIOPSY (EBUS-MCB) IN PATIENTS WITH NONDIAGNOSTIC RAPID ON-SITE EVALUATION (ROSE). SECONDARY AIMS INCLUDED AN ASSESSMENT OF THE SAFETY OF THE PROCEDURE. A TOTAL OF 46 PATIENTS WERE INCLUDED. OF THE 46 CASES WHERE EBUS-MCB WAS PERFORMED, A DEFINITE DIAGNOSIS WAS ACHIEVED IN 33 (71.7%) CASES. OF THE 32 CASES WITH A NONDIAGNOSTIC ROSE, EBUS-MCB CONFIRMED THE DIAGNOSIS IN 19 (59.3%) CASES. THUS, THE ADDITIVE DIAGNOSTIC YIELD OF EBUS-MCB OVER EBUS-TBNA WAS IN 14/32 CASES (43.7%). THE ADDITIONAL TIME REQUIRED FOR PERFORMING CRYOBIOPSY IN THE STUDY WAS 11 ± 2 MINUTES. BACKGROUND: ENDOBRONCHIAL ULTRASOUND-GUIDED TRANSBRONCHIAL NEEDLE ASPIRATION (EBUS-TBNA) IS CONSIDERED THE INVESTIGATION OF CHOICE FOR SAMPLING MEDIASTINAL NODES. A MAJOR DRAWBACK OF EBUS-TBNA IS ITS LOWER DIAGNOSTIC YIELD FOR LYMPHOMA AND BENIGN DISEASES. EBUS-GUIDED MEDIASTINAL CRYOBIOPSY (EBUS-MCB) IS A NOVEL TECHNIQUE THAT PROVIDES LARGER NODAL BIOPSY SAMPLES, WITH AN ACCEPTABLE SAFETY PROFILE. THIS STUDY AIMED TO EVALUATE THE DIAGNOSTIC YIELD OF EBUS-MCB IN PATIENTS WITH AN INCONCLUSIVE RAPID ON-SITE EVALUATION (ROSE). METHODS: THIS IS A PROSPECTIVE STUDY OF PATIENTS WHO UNDERWENT EBUS-TBNA FOR UNDIAGNOSED MEDIASTINAL LYMPHADENOPATHY. PATIENTS IN WHOM ROSE DID NOT YIELD A DIAGNOSIS (NONDIAGNOSTIC ROSE) OR ROSE REVEALED SCANTY ATYPICAL CELLS (INADEQUATE ROSE) WERE SUBJECTED TO EBUS-MCB. THE DIAGNOSTIC YIELD, ADEQUACY, AND COMPLICATIONS OF EBUS-MCB WERE ANALYZED. RESULTS: OF THE 196 PATIENTS UNDERGOING EBUS-TBNA, 46 PATIENTS UNDERWENT EBUS-MCB. THIRTY-TWO CASES UNDERWENT EBUS-MCB FOR A NONDIAGNOSTIC ROSE. EBUS-MCB CONFIRMED THE DIAGNOSIS IN 19/32 (59.3%) CASES. THE ADDITIVE DIAGNOSTIC YIELD OF EBUS-MCB OVER EBUS-TBNA WAS 43.7% (14/32 CASES). IN ALL 14 CASES WHERE EBUS-MCB WAS PERFORMED FOR AN INADEQUATE ROSE, THE MATERIAL OBTAINED BY EBUS-MCB WAS ADEQUATE FOR ANCILLARY STUDIES. MINOR BLEED WAS NOTED IN 13/46 CASES, WHICH SETTLED WITH CONSERVATIVE MEASURES. ONE CASE HAD A MODERATE BLEED, REQUIRING A CRYOEXTRACTION OF THE BLOOD CLOT FROM THE AIRWAYS. CONCLUSION: EBUS-MCB HAS A DIAGNOSTIC YIELD OF 59.3% WHEN PERFORMED IN CASES WITH A NONDIAGNOSTIC EBUS-ROSE. THE TISSUE OBTAINED BY EBUS-MCB IS ADEQUATE FOR ANCILLARY STUDIES. THE STUDY PROPOSE EBUS-MCB AS AN ADDITIONAL DIAGNOSTIC STEP IN CASES WITH AN INCONCLUSIVE ROSE WHILE PERFORMING EBUS-TBNA. LARGER STUDIES ARE, HOWEVER, NEEDED BEFORE EBUS-MCB CAN BE INCORPORATED IN THE DIAGNOSTIC ALGORITHM FOR THE EVALUATION OF MEDIASTINAL LESIONS. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS MILD BLEEDING (13), MODERATE BLEEDING (1).
