after period of scope use two: ((b)(6) 2020-(b)(6) 2021) there is leakage from biopsy channel.Channel cover has deep scratches.Deep scratches.The ob-lens is chipped.The rubber glue is chipped.Physical inspection of the device after period of scope use three: ((b)(6) 2021- (b)(6) 2021) small black debris was noted at 170mm from the distal end opening.A kink was found on the channel wall of the connecting tube, approximately 65mm from the suction cylinder.A kink was confirmed in suction channel located approximately 120mm from the opening of the connector.The opening of the auxiliary channel at the distal end side has debris.Scratches were present on the insertion tube close to the boot.A kink was confirmed in lg-tube near control section.The scope passed leakage test.An endoscopic support specialist (ess) provided education to the facility on four different occasions between (b)(6) 2019 and (b)(6) 2021.((b)(6) 2019, (b)(6) 2020, (b)(6) 2020, and (b)(6) 2021.The purpose of the education: review scope handling and reprocessing of scopes.Session: general overview and demonstration of handling scopes during procedures and while transporting, along with reprocessing (pre-clean through drying).Lastly, common scope repairs olympus receives from the user were reviewed.No gaps in reprocessing procedures were observed during these times.Third party lab culturing of the scope showed: insertion section: positive: bacillus subtilis air/water channel: positive: negative biopsy channel: positive: pseudomonas aeruginosa (not specified whether it was cppa or not) auxiliary water channel: positive: brevibacillus species the customer approved destructive testing of the device to help determine root cause.Results of destructive testing performed (b)(6) 2021 showed: 1- evaluation of disassembled scope connector: trace of the previous repair and water invasion 2-evaluation of disassembled control section: suction channel is kinked.No evidence of water invasion, internal corrosion, or adhered debris 3-evaluation of suction channel and air/water channel: performed leakage test by soaking.No leakage found.4-evaluation of bending section: braids: no abnormality.Biopsy channel distal end side: slightly stained.5-evaluation of biopsy channel: no leakage confirmed by soaking.White debris and black debris inside the channel.6-evaluation of biopsy channel white debris: protein like spectrum was detected by fourier transform infra-red spectography (ft-ir).7-evaluation of biopsy channel black debris: the debris had black are and translucent black area.Black area: possibly silicone related black debris such as black silicone rubber translucent area part: possibly calcium soap, product of hard water and fatty acid 8-evaluation of glue between cover body and cover: no trace of corrosion or debris confirmed at glue no debris found at channel opening of biopsy channel no trace of corrosion or debris confirmed at glued area of all channels or pipe on cover body 9-evaluation of glue between control body and cover-area 2 debris noted at channel opening of auxiliary water channel confirmed seepage of glue fixing cover in channel.Seepage of glue occurs at assembly.No abnormality such as narrowed channel.No debris other than the glue.10-evaluation of lever mount: white dot like stains in the channel.Unable to analyze by energy-dispersive x-ray spectography (eds).11-evaluation of suction cylinder and air/water cylinder: trace fragments of cleaning brush.No corrosion or adhered debris 12-evaluation of inside the nozzle: no debris in the nozzle 13-evaluation of connecting mouthpiece on auxiliary water channel in control section: brown debris around the mouthpiece.Eds result: molycote & organic substance, rusty iron & organic substance.Ft-ir result: organic substance is possibly mixture of carboxylic salt and rust, originated from chemical solution and/or tap water.White powder inside the mouthpiece: unable to analyze by eds.Conclusion summary: the definitive root cause of the reported events cannot be specified.Olympus received the scope as an adverse event complaint after period of the scope use three and the following information was provided.According to the information from the user, reprocessing procedures conducted by the user was not deviated from instructions for use (ifu).Although the subject scope had been used for over 200 patient procedures during the same time period the cluster occurred, only the six patients were infected.Moreover, each infection was identified at various time.After the scope was used for patient, the subject scope was repaired for leakage by olympus.The result of culture test was negative when the test was performed at the user facility, when culture test was performed by the third-party labs, pseudomonas aeruginosa (unspecified if it was cppa) was detected from biopsy channel.White debris was detected from biopsy channel.According to ft-ir analysis, protein like spectrum was confirmed.Additionally, a translucent black debris was found in the biopsy channel.We cannot rule out the possibility that the debris remained adhered during reprocessing.The instructions for use warns on insufficient reprocessing as follows: reprocessing manual:1.4 precautions: warning: an insufficiently reprocessed endoscope and/or accessory may pose an infection control risk to the patients and/or operators who touch them.
Manufacturer Narrative
This report is being supplemented to provide additional information based on the legal manufacturer's final investigation (per capa-200413).It has been over 7 years since the subject device was manufactured.Based on the results of the additional investigation, the following was determined: 1.A cluster of six patients had been diagnosed with the same strain of cppa ¿ although the root cause could not be determined, only 6 patients out of 200 in which the device was used were infected.In addition, the reprocessing process conducted by the user did not deviate from the instructions for use (ifu).2.Positive in culture test ¿ although the root cause could not be determined, the result of the culture test was negative when the test was performed at the user facility.In addition, when culture test was performed by the third-party labs, pseudomonas aeruginosa was detected from biopsy channel.Whether it was cppa or not was unknown.3.Debris inside of auxiliary water channel ¿ the foreign material at the channel opening of the auxiliary water channel was the adhesive that fixes the c-cover.It is likely that seepage of glue may have occurred during assembly of the device.The foreign material at the connecting mouthpiece on the auxiliary water channel in the control section may be the mixture of moly cote, carboxylates, and rusts.It could not be determined why the foreign material remained.According to the customer¿s reprocessing process for the areas where foreign material remained, obvious deviation from ifu was not confirmed.4.Small black debris/stain in biopsy channel - although the white and black debris (black part and translucent black part) couldn't be identified, the component analysis indicated that it is likely that the white debris is protein, the black debris (black part) is originated from silicon, and the black debris (translucent black part) is a possibly calcium soap that the mixture of hard water and fatty acid.It could not be determined why the foreign material remained.According to the customer¿s reprocessing process for the areas where foreign material remained, obvious deviation from ifu was not confirmed.5.White stain in the k-mount ¿ although the root cause could not be determined, it was confirmed that there was a white stain at the k-mount.However, the specifics of the white stain could not be identified.It could not be determined why the foreign material remained.According to the customer¿s reprocessing process for the areas where foreign material remained, obvious deviation from ifu was not confirmed.Olympus will continue to monitor field performance for this device.
