This report is being updated to report additional information reported by the customer and investigation findings.New information is reported in h6, and h10.Since the subject device was not sent to olympus, there was no device inspection result.According to the endoscopic support specialist who examined the device onsite, there was peeling of the adhesive rubber glue and scape marks on the insertion tube.Repair history review: the subject device has not been repaired within the past one year.The device history record (dhr) for the reported serial number was reviewed.It is confirmed that the device met all design and safety specification when it was shipped.The instructions for use shipped with the device provides the user with the following information related to the reported event: 4.1 precautions: do not retrieve the stent through the instrument channel of the endoscope.A stent or piece(s) of a stent may stay in the instrument channel or the suction channel of the endoscope even after reprocessing.It may cause incomplete reprocessing, and pose an infection control risk, cause equipment damage, or reduce performance.Operation manual: 3.8 inspection of the endoscopic system: inspection of the instrument channel and forceps elevator: 3 insert the endotherapy accessory through the biopsy valve.Confirm that the endotherapy accessory extends smoothly from the distal end of the endoscope.Also, make sure that no foreign objects come out of the distal end of the endoscope.1.4 precautions: all channels of the endoscope, including the instrument channel, and all accessories used with the endoscope during the patient procedure, such as all valves, must be reprocessed after each patient procedure, even if the channels or accessories were not used during the patient procedure.Insufficient reprocessing of these components may pose an infection control risk to patients and/or operators.[conclusion root cause of the suggested event was not specified.Consideration according to investigation findings, we presumed that the suggested event occurred by the following mechanism.I) when the user retrieved the stent through biopsy channel during previous ercp, a part of the stent got caught in the channel and remained there.Ii) since user¿s reprocessing was different from ifu recommendation, the stent caught in the channel was not removed.Iii) the presence of the stent inside the channel could not be detected due to inadequate inspection prior to use.The stent caught in the biopsy channel could have been detected during inspection prior to use since ifu (operation manual) states as follows: operation manual: 3.8 inspection of the endoscopic system: inspection of the instrument channel and forceps elevator: 3 insert the endotherapy accessory through the biopsy valve.Confirm that the endotherapy accessory extends smoothly from the distal end of the endoscope.Also, make sure that no foreign objects come out of the distal end of the endoscope.Moreover, ifu (reprocessing manual) states as follows: 1.4 precautions: all channels of the endoscope, including the instrument channel, and all accessories used with the endoscope during the patient procedure, such as all valves, must be reprocessed after each patient procedure, even if the channels or accessories were not used during the patient procedure.Insufficient reprocessing of these components may pose an infection control risk to patients and/or operators.
