    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "EFFICACY AND SAFETY OF ONE-STEP KNIFE COMPARED TO CONVENTIONAL INSULATED-TIP KNIFE FOR ENDOSCOPIC SUBMUCOSAL DISSECTION: A PRELIMINARY STUDY WITH PROSPECTIVE DATA COLLECTION AND RETROSPECTIVE REVIEW." THIS PROSPECTIVE DATA COLLECTION AND RETROSPECTIVE REVIEW, AIMED TO COMPARE THE INSULATED TIP TYPE OF ONE STEP KNIFE (OSK) AND CONVENTIONAL KNIFE (CK) IN TERMS OF PROCEDURE TIME AND COMPLICATION RATE. A TOTAL OF 203 PATIENTS WERE INCLUDED IN THE STUDY (OSK (N = 102) & CK (N = 101). THE PROCEDURE TIME OF ESD WAS SHORTER IN OSK GROUP ALL SITUATIONS EXCEPT FOR THE RESECTION OF SUBMUCOSAL CANCER. THE PROCEDURE TIME FOR EACH LOCATION WAS MORE REDUCED IN THE BODY (MEDIAN 14 VS. 19 MIN P<0.01) THAN THE ANTRUM (MEDIAN 10 VS. 14 MIN, P=0.01) IN THE OSK GROUP. THE COMPLICATIONS WERE NOT SIGNIFICANTLY DIFFERENT BETWEEN BOTH GROUPS. IN SUMMARY, OSK IS A SAFE AND EFFECTIVE KNIFE COMPARED TO CONVENTIONAL KNIVES AND SHOWED FASTER PROCEDURE TIME, ESPECIALLY IN GASTRIC BODY LESIONS. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS: BLEEDING - 8 PATIENTS. PERFORATION - 3 PATIENTS. ALL COMPLICATIONS WERE CONTROLLED BY ENDOSCOPIC MANAGEMENT. THIS LITERATURE ARTICLE REQUIRES 2 REPORTS. THE RELATED PATIENT IDENTIFIERS ARE AS FOLLOWS: (B)(6) (FOR KD-611L). (B)(6) (FOR GIF-HQ290). THERE IS NO REPORT OF ANY OLYMPUS DEVICE MALFUNCTION IN ANY PROCEDURE DESCRIBED IN THIS STUDY.
