    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE FOLLOWING ARTICLE: "DETECTION OF SUPERFICIAL ESOPHAGEAL SQUAMOUS CELL NEOPLASIA BY CHROMOENDOSCOPY-GUIDED CONFOCAL LASER ENDOMICROSCOPY" BY JIN HUANG, YUN-SHENG YANG, ZHONG-SHENG LU, ET AL. THE SINGLE-CENTER STUDY WAS AIMED TO DETERMINE THE DIAGNOSTIC POTENTIAL OF CONFOCAL LASER ENDOMICROSCOPY (CLE) COMBINED WITH LUGOL'S IODINE CHROMOENDOSCOPY (LIC) IN DETECTING SUPERFICIAL ESOPHAGEAL SQUAMOUS CELL NEOPLASIA (ESCN) USING A HISTOLOGICAL EXAMINATION OF EN BLOC ENDOSCOPIC RESECTION (ER) SPECIMENS AS THE STANDARD. THE LIC- CLE WAS PERFORMED IN 52 ENROLLED PATIENTS. IN THE SAME PATIENTS, A CHROMOENDOSCOPY-GUIDED BIOPSY WAS PERFORMED BY ANOTHER ENDOSCOPIST, AND THEY WERE COMPARED FOR THE DETECTION RATES. THE REPORTED SENSITIVITY, SPECIFICITY, NEGATIVE PREDICTIVE VALUE, AND POSITIVE PREDICTIVE VALUE OF CHROMOENDOSCOPY-GUIDED CLE WERE 95.7%, 90%, 81.8%, AND 97.8%, RESPECTIVELY. IN CONCLUSION, THE STUDY DEMONSTRATED THAT ESCN COULD BE DIAGNOSED RELIABLY BY LIC-CLE. A TOTAL OF 56 LESIONS IN 52 PATIENTS WERE ENROLLED FOR THE STUDY, INCLUDING 16 FEMALES AND 36 MALES (MEAN AGE, 60.5 YEARS; RANGE, 43-78 YEARS). THE AUTHORS USED MULTIPLE OLYMPUS DEVICES AND DID NOT SPECIFY THE DEVICES USED IN RELATION TO THE ADVERSE EVENTS EXPERIENCED. THEREFORE ALL OLYMPUS DEVICES WILL BE REPORTED. PATIENT IDENTIFIER (B)(6) IS FOR KD-610L; COMPLAINT 2 IS FOR KD-1L; COMPLAINT 3 IS FOR FD-410LR; COMPLAINT 4 IS FOR GIF-H260; COMPLAINT 5 IS FOR CLV-260SL; COMPLAINT 6 IS FOR GIFQ260J. THE ADVERSE EVENTS REPORTED: ENDOSCOPIC HEMOSTASIS WAS PERFORMED EITHER WITH THE KNIFE OR HEMOSTATIC FORCEPS (FD-410LR; OLYMPUS OPTICAL CO., LTD., (B)(4)) WHENEVER BLEEDING WAS NOTED. AFTER DISSECTION, PREVENTIVE ENDOSCOPIC HEMOSTASIS WAS PERFORMED FOR ANY OOZING OR EXPOSED VESSEL. MINOR BLEEDING WAS ENCOUNTERED IN ALL ER PROCEDURES, BUT SUCCESSFUL HEMOSTASIS WAS ALWAYS ACHIEVED USING THERMOCOAGULATION. NO PATIENT EXPERIENCED MASSIVE HEMORRHAGE REQUIRING A BLOOD TRANSFUSION OR POSTPROCEDURAL EMERGENT ENDOSCOPY. NO DELAYED HEMORRHAGE OCCURRED. EXPOSURE OF THE MUSCULAR LAYER DURING ESD OCCURRED IN FOUR CASES, BUT NO OVERT ESOPHAGEAL PERFORATION. TREATMENT NOT SPECIFIED. THIS IS REPORT 1 OF 6 FOR PATIENT IDENTIFIER (B)(6) IS FOR KD-610L.
