    THIS REPORT IS RELATED TO THE FOLLOWING LINKED PATIENT IDENTIFIERS: (B)(6). E1 - INITIAL REPORTER ESTABLISHMENT NAME: (B)(6). SINCE THE LITERATURE STATED "19G OR 22G NEEDLE (EZ SHOT 3 PLUS)", OLYMPUS SELECTED ¿NA-U200H-8019¿ AS THE REPRESENTATIVE MODEL AND INITIATED A COMPLAINT. ATTEMPTS TO OBTAIN ADDITIONAL INFORMATION WERE MADE BUT WERE UNSUCCESSFUL. THE DEVICE WAS NOT RETURNED FOR EVALUATION; THEREFORE, A DEFINITIVE ROOT CAUSE COULD NOT BE DETERMINED. THE MOST PROBABLE CAUSE WAS NOT ESTABLISHED; THE INVESTIGATION FINDINGS DO NOT LEAD TO A CLEAR CONCLUSION AS NO MALFUNCTIONS OF THE SUBJECT DEVICE HAVE BEEN REPORTED AND A CAUSAL RELATIONSHIP BETWEEN THE DEVICE AND THE HEALTH HAZARDS COULD NOT BE ESTABLISHED. SHOULD ADDITIONAL RELEVANT INFORMATION BECOME AVAILABLE, A SUPPLEMENTAL REPORT WILL BE SUBMITTED. OLYMPUS WILL CONTINUE TO MONITOR FIELD PERFORMANCE FOR THIS DEVICE.

    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED ¿TRANSLUMINAL ANTEGRADE DRILL DILATION TECHNIQUE FOR HEPATICOJEJUNOSTOMY STRICTURE WITH CHOLANGIOSCOPIC EVALUATION (WITH VIDEO)¿. BACKGROUND AND STUDY AIMS : BALLOON DILATION AND PLASTIC STENT DEPLOYMENT HAVE BEEN PERFORMED AS HEPATICOJEJUNOSTOMY STRICTURE (HJS) TREATMENT TECHNIQUES UNDER ENDOSCOPIC ULTRASOUND GUIDANCE (EUS). ALTHOUGH THESE TECHNIQUES HAVE SHOWN FAVORABLE CLINICAL RESULTS, THE TREATMENT PERIOD CAN BE LONG BECAUSE STENT DEPLOYMENT IS REQUIRED. IN ADDITION, HJS MAY RECUR EVEN AFTER TREATMENT BECAUSE THE SCAR TISSUE ITSELF REMAINS. TO OVERCOME THESE CHALLENGES, WE DEVELOPED AN EUS-GUIDED ANTEGRADE DRILL DILATION TECHNIQUE FOR TREATING HJS. THE AIM OF THIS STUDY WAS TO EVALUATE THE TECHNICAL FEASIBILITY AND SAFETY OF THIS TECHNIQUE IN TERMS OF THE PRE- AND POST-CHOLANGIOSCOPIC FINDINGS. METHODS: THIS RETROSPECTIVE STUDY INCLUDED CONSECUTIVE PATIENTS WHOSE CONDITIONS WERE COMPLICATED WITH SYMPTOMATIC HJS BETWEEN NOVEMBER 2022 AND FEBRUARY 2023. TRANSLUMINAL ANTEGRADE DRILL DILATION (TAD) USING A NOVEL DRILL DILATOR WAS ATTEMPTED WITHIN 14 DAYS AFTER EUS-GUIDED HEPATICOGASTROSTOMY (HGS). HJS WAS DIAGNOSED WITH CHOLANGIOSCOPY BEFORE TAD, AND RESOLUTION WAS EVALUATED AFTER TAD USING CHOLANGIOSCOPY. RESULTS: TAD WAS ATTEMPTED AT APPROXIMATELY 11 DAYS AFTER EUS-HGS. THE CHOLANGIOSCOPE WAS INSERTED SUCCESSFULLY IN ALL PATIENTS AFTER THIS PROCEDURE. CHOLANGIOSCOPY REVEALED STRICTURE WITHOUT EVIDENCE OF MALIGNANCY IN 19 PATIENTS. IN THE REMAINING THREE PATIENTS, STRICTURE WAS NOT OBSERVED AND THESE PATIENTS UNDERWENT STENT EXCHANGE RATHER THAN TAD. AMONG THE 19 PATIENTS, PASSAGE OF THE GUIDEWIRE ACROSS THE HJS INTO THE INTESTINE WAS UNSUCCESSFUL IN FOUR PATIENTS, AND THE TECHNICAL SUCCESS RATE FOR THIS PROCEDURE WAS 78.9%. TAD WAS SUCCESSFUL IN ALL 15 PATIENTS IN WHOM PASSAGE OF THE GUIDEWIRE WAS ACHIEVED. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS: CHOLANGITIS (1 PATIENT). ABDOMINAL PAIN (2 PATIENTS). CONCLUSIONS: IN CONCLUSION, TAD APPEARS TO BE TECHNICALLY FEASIBLE AND SAFE.
