  OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "FEASIBILITY OF MODIFIED ENDOBRONCHIAL ULTRASOUND-GUIDED INTRANODAL FORCEPS BIOPSY: A RETROSPECTIVE ANALYSIS." THE RETROSPECTIVE STUDY WAS TO ASSESS THE FEASIBILITY OF THE MODIFIED EBUS- INTRANODAL FORCEPS BIOPSY (IFB) TECHNIQUE, WHICH COMBINES STANDARD-SIZED FORCEPS WITH STANDARD ENDOBRONCHIAL ULTRASOUND (EBUS) TRANSBRONCHIAL NEEDLE ASPIRATION (TBNA) EQUIPMENT. A TOTAL OF 195 PATIENTS WERE INCLUDED. IFB WAS TECHNICALLY SUCCESSFUL IN 177 OF 195 CASES (90.8%). THE DIAGNOSTIC ACCURACY WAS 99.5% (193 OF 194 CASES). ONE PATIENT WAS LOST TO FOLLOW-UP. UNIVARIABLE ANALYSES DID NOT IDENTIFY ANY FACTORS INVOLVED IN TECHNICAL IFB FAILURE. AMONG THE DIAGNOSED CASES, THREE (1.5%) WERE DIAGNOSED. THE MEDIAN (RANGE) HISTOLOGICAL SCORES OF TBNA AND IFB SPECIMENS WERE 1.50 (0¿2) AND 1.67 (0¿2), RESPECTIVELY, WHICH WERE SIGNIFICANTLY DIFFERENT (P = 0.032). IN CONCLUSION, MODIFIED EBUS-IFB, COMBINING STANDARD-SIZED FORCEPS AND THE USUAL EQUIPMENT FOR EBUS TBNA, IS FEASIBLE WITH FEW MAJOR COMPLICATIONS. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS: PNEUMONIA - 1 PATIENT, PNEUMOTHORAX REQUIRING THORACIC DRAINAGE - 1 PATIENT, MINOR BLEEDING - 25 PATIENTS.
