Correction to g3 of the initial medwatch.The aware date should be 29-dec-2021.This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.It has been over 9 years since the subject device was manufactured.Based on the results of the investigation, a definitive root cause could not be established.The suggested phenomenon was presumed to be due to the following: ·because of inappropriate device handling, the biopsy channel was deformed.And the biopsy channel was clogged with an endo therapy accessory, because the user inserted the endo therapy accessory into the biopsy channel while the biopsy channel was deformed.·during the procedure performed before detection of the suggested event, a way of using an endo therapy accessory by the user was not appropriate, and then, the biopsy channel was clogged with the endo therapy accessory.Users can detect the suggested event properly by handling the device in accordance with the following instructions for use (ifu): "·inspection of the instrument channel - insert the endotherapy accessory through the biopsy valve.Confirm that the endotherapy accessory extends smoothly from the distal end.Also make sure that no foreign objects come out of the distal end.".Users can decrease/prevent the suggested event by handling the device in accordance with the following ifu: "·do not strike, hit, or drop the endoscope¿s distal end, insertion tube, bending section, control section, universal cord, or endoscope connector.Also, do not bend, pull, or twist the endoscope¿s distal end, insertion tube, bending section, control section, universal cord, or endoscope connector with excessive force.The endoscope may be damaged and could cause patient injury, burns, bleeding, and/or perforations.It could also cause parts of the endoscope to fall off inside the patient.·do not coil the insertion tube or universal cord with a diameter of less than 12 cm.Equipment damage can result.·if insertion or withdrawal of endotherapy accessories is difficult, straighten the bending section as much as possible without losing the endoscopic image.Inserting or withdrawing endotherapy accessories with excessive force may damage the instrument channel or endotherapy accessories and could cause some parts to fall off and/or cause patient injury.".Olympus will continue to monitor field performance for this device.
