    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE LITERATURE TITLED "THE EVALUATION OF BILATERAL STENTING USING BRAIDED OR LASER-CUT SELF-EXPANDABLE METALLIC STENT FOR MALIGNANT HILAR BILIARY OBSTRUCTION." THIS RETROSPECTIVE STUDY AIMS TO EVALUATE THE DIFFERENCES IN CLINICAL FEATURES AND THE PROPER USE OF LASER-CUT AND BRAIDED SELF-EXPANDABLE METALLIC STENT (SEMS) PLACEMENTS USING THE STENT-IN-STENT (SIS) METHOD, INCLUDING ENDOSCOPIC REINTERVENTION (ERI), FOR UNRESECTABLE MALIGNANT HILAR BILIARY OBSTRUCTION (UMHBO). A TOTAL OF 78 PATIENTS WERE INCLUDED, 33 IN LASER CUT SEMS AND 45 IN BRAIDED SEMS GROUP. TECHNICAL SUCCESS WAS ACHIEVED IN 32 OF 33 CASES (97.0%) IN THE LASER-CUT GROUP AND IN 43 OF 45 CASES (95.6%) IN THE BRAIDED GROUP (P=1.0). NO SIGNIFICANT DIFFERENCE IN THE CLINICAL SUCCESS RATE WAS NOTED BETWEEN THE TWO GROUPS [LASER-CUT GROUP: 97.0% (32/33); BRAIDED GROUP: 95.6% (43/45), P=1.0]. THE CLINICAL SUCCESS OF ERI WAS ACHIEVED IN ALL TECHNICALLY SUCCESSFUL ERI CASES IN BOTH GROUPS. NO SIGNIFICANT DIFFERENCE IN THE CLINICAL SUCCESS RATE WAS DETECTED BETWEEN THE TWO GROUPS [LASER-CUT GROUP: 60.0% (9/15); BRAIDED GROUP: 85.0% (17/20), P=1.0]. BASED ON THESE RESULTS, THE MEDIAN PROCEDURE TIME OF ERI WAS SIGNIFICANTLY LONGER IN THE LASER CUT GROUP [38 (IQR 22¿55) MINUTES] THAN IN THE BRAIDED GROUP [22 (IQR 19¿37) MINUTES] (P=0.02). TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS PANCREATITIS (4), CHOLECYSTITIS (10), DEATH (UNKNOWN - NOT SPECIFIED). ALL POST-ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY PANCREATITIS (PEP) WERE SUCCESSFULLY MANAGED CONSERVATIVELY AND CHOLECYSTITIS WAS SUCCESSFULLY MANAGED WITH PERCUTANEOUS DRAINAGE. RELATED PATIENT IDENTIFIERS: (ADVERSE EVENTS): (B)(6) EVIS DUODENOVIDEOSCOPE (TJF-200), (B)(6) EVIS DUODENOVIDEOSCOPE (JF-240), (B)(6) EVIS LUCERA DUODENOVIDEOSCOPE (TJF-260V). (DEATHS): (B)(6) EVIS DUODENOVIDEOSCOPE (TJF-200), (B)(6) EVIS DUODENOVIDEOSCOPE (JF-240), (B)(6) EVIS LUCERA DUODENOVIDEOSCOPE (TJF-260V).
