    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "THE ASSESSMENT OF THE ASGE-GRADING SYSTEM OF ERCP: A LARGE-SAMPLE RETROSPECTIVE STUDY." THIS RETROSPECTIVE STUDY AIMED TO ASSESS THE ASSOCIATION BETWEEN THE DEGREE OF DIFFICULTY FOR ERCP AND THE RATES OF SUCCESS AND ADVERSE EVENT, IN TURN DEMONSTRATING THE VALIDITY AND PRACTICALITY OF THIS SYSTEM. A TOTAL OF 20,652 ERCP PROCEDURES PERFORMED DURING THE STUDY PERIOD WERE ANALYZED. THE OVERALL SUCCESS RATE INCREASED FROM 92.8% TO 94.0%, WHILE THE DISTRIBUTION OF PROCEDURES AND THE INCIDENCE OF COMPLICATIONS SHOWED LITTLE VARIATION. THE SUCCESS RATE REVEALED A SIGNIFICANTLY DECREASING TREND WITH INCREASING DIFFICULTY (RANGING FROM 55.6 TO 98.6%), MAINLY FOR BILIARY DISEASES. IN ADDITION, THE DIFFICULTY SCALE WAS NOT ASSOCIATED WITH ANY DIFFERENCES IN THE RATE OF ADVERSE EVENT, EXCEPT FOR THE PANCREATITIS FOR GRADE 1 PROCEDURES, WHICH HAD A LOW INCIDENCE. THIS STUDY CONCLUDED THAT THE ASGE-GRADING SYSTEM CAN HELP PREDICT THE SUCCESS RATE OF ERCP PROCEDURES BUT SHOWED POOR PERFORMANCE IN PREDICTING ADVERSE EVENTS. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENT: COHORT - 1. PANCREATITIS - 511 PATIENTS. BLEEDING - 410 PATIENTS. CHOLANGITIS - 62 PATIENTS. PERFORATION - 26 PATIENTS. COHORT - 2. PANCREATITIS - 536 PATIENTS. BLEEDING - 412 PATIENTS. CHOLANGITIS - 83 PATIENTS. PERFORATION - 32 PATIENTS. THIS LITERATURE ARTICLE REQUIRES 3 REPORTS. THE RELATED PATIENT IDENTIFIERS ARE AS FOLLOWS: (B)(6)/KD-V441M, (B)(6)/JF-240 AND (B)(6)/JF-260V. THIS MEDWATCH REPORT IS FOR PATIENT IDENTIFIER (B)(6). THERE IS NO REPORT OF ANY OLYMPUS DEVICE MALFUNCTION IN ANY PROCEDURE DESCRIBED IN THIS STUDY.
