Event or Problem Description
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 this literature article requires 4 reports.The related patient identifiers are as follows: -(b)(6).This medwatch report is for patient identifier (b)(6).There is no report of any olympus device malfunction in any procedure described in this study.
