    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "CURATIVE VALUE OF UNDERWATER ENDOSCOPIC MUCOSAL RESECTION FOR SUBMUCOSALLY INVASIVE COLORECTAL CANCER." THIS WAS A RETROSPECTIVE, OBSERVATIONAL STUDY EVALUATED THE FEASIBILITY OF UNDERWATER ENDOSCOPIC MUCOSAL RESECTION (UEMR) FOR PATHOLOGICALLY INVASIVE COLORECTAL CANCER (PT1-CRC). A TOTAL OF 31 PATIENTS WERE TREATED WITH UEMR AND 32 PATIENTS WERE TREATED WITH CONVENTIONAL ENDOSCOPIC MUCOSAL RESECTION (CEMR). THE ENDOSCOPIC COMPLETE RESECTION RATE WAS 100%. TOTAL EN BLOC RESECTION WAS OBTAINED IN 77%, AND THE VM0, HM0, AND R0 RESECTION RATES WAS 81%, 58%, AND 55%. THE ENDOSCOPIC COMPLETE RESECTION RATE WAS 100% IN CEMR. CEMR SHOWED A SIMILAR EN BLOC (78%), VM0 (78%), HM0 (66%), AND R0 RESECTION RATES (63%). LYMPHO-VASCULAR INVOLVEMENT WAS OBSERVED IN SIX PATIENTS (18%), AND UNFAVORABLE FEATURES FOR LNM WERE SEEN IN 22 PATIENTS (68%) IN THE CEMR GROUP. REGARDING PT1A LESIONS (N = 6), THE VM0 AND CLINICALLY OR PATHOLOGICALLY CURATIVE RESECTION RATES IN CEMR WERE SIMILAR TO THOSE OF UEMR (100%, 67%, AND 100%). UEMR HAS A FEASIBLE VM0 RATE FOR RESECTING PT1-CRC¿ESPECIALLY FOR PT1A CRC¿WITHOUT CHARACTERISTICS OF DEEP SUBMUCOSAL INVASION. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS: UEMR COHORT: DELAYED BLEEDING - 2 PATIENTS, NO PERFORATION OR POST-ELECTROCOAGULATION SYNDROME OCCURRED AFTER EITHER PROCEDURE. ALL THESE ADVERSE EVENTS WERE CURABLE WITH CONSERVATIVE TREATMENT. THE EVENT DATE WAS REPORTED AS THE PUBLICATION DATE OF THE LITERATURE. THIS LITERATURE ARTICLE REQUIRES 2 REPORTS. THE RELATED PATIENT IDENTIFIERS ARE AS FOLLOWS: (B)(6) IS FOR SCOPE MODEL PCF-Q260AZI (B)(6) IS FOR SCOPE MODEL PCF-H290TI 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.
