    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE FOLLOWING LITERATURE TITLED "TREATMENT RESULTS OF ENDOSCOPIC MUCOSAL RESECTION WITH A LIGATION DEVICE FOR DUODENAL NEUROENDOCRINE TUMORS". LITERATURE SUMMARY: THIS STUDY EXAMINED THE TREATMENT RESULTS OF ENDOSCOPIC MUCOSAL RESECTION WITH A LIGATION DEVICE (EMR-L) FOR THE REMOVAL OF DUODENAL NETS LOCATED IN THE SUBMUCOSAL LAYER WITHOUT METASTASIS. EMR-L CAN BE PERFORMED WITH LESS TECHNICAL SKILL, AND THE LIGATION DEVICE REDUCES THE RATE OF POSITIVE VERTICAL MARGIN. THE EN BLOC RESECTION RATE AND ENDOSCOPIC COMPLETE RESECTION RATE WERE BOTH 100%. COMPLETE RESECTION WAS ACHIEVED PATHOLOGICALLY IN 7 LESIONS (70.0%). THE VERTICAL MARGINS WERE NEGATIVE IN ALL CASES. LYMPHATIC VESSEL INVASION WAS OBSERVED IN THREE PATIENTS, ALL OF WHOM UNDERWENT ADDITIONAL SURGERY WITH LYMPH NODE DISSECTION (ONE OF THEM ALSO EXHIBITED BLOOD VESSEL INVASION AND A POSITIVE HORIZONTAL MARGIN). NO EVIDENCE OF RESIDUAL TUMORS OR LYMPH NODE METASTASIS WAS OBSERVED IN ANY OF THE PATIENTS. NO RECURRENCE WAS OBSERVED IN ANY OF THE 10 PATIENTS (MEAN FOLLOW-UP PERIOD: 18.6 MONTHS). ONE PATIENT (10.0%) EXPERIENCED INTRAOPERATIVE BLEEDING. PERFORATION OCCURRED IN 1 PATIENT (10.0%), BUT THE CONDITION WAS MANAGED WELL BY CONSERVATIVE THERAPY. EMR-L WAS AN ACCEPTABLE METHOD FOR ENDOSCOPICALLY RESECTING SUBMUCOSAL DUODENAL NETS, AND THE NETS RESECTED BY EMR-L WERE TUMOR-NEGATIVE IN THE VERTICAL MARGINS. AN ASSESSMENT BY ULTRASONIC ENDOSCOPY CATHETER PROBES (UM3R) CONFIRMED THE SIZE OF EACH DUODENAL NET AND ITS LOCALIZATION IN THE SUBMUCOSAL LAYER. THE AUTHORS DID NOT SPECIFY WHICH DEVICES CAUSED OR CONTRIBUTED TO THE INTRAPROCEDURAL BLEEDING AND PERFORATION. THEREFORE, THE OLYMPUS PROBE WILL BE REPORTED. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS: INTRAPROCEDURE BLEEDING - (1). PERFORATION - (1). THIS ARTICLE INCLUDES 5 REPORTS AS FOLLOWS: PATIENT IDENTIFIER (B)(6) FOR GIF-Q260J. PATIENT IDENTIFIER (B)(6) FOR NM-610L-0423. PATIENT IDENTIFIER (B)(6) FOR SD-210L-10. PATIENT IDENTIFIER (B)(6) FOR UM-S20-20R. PATIENT IDENTIFIER (B)(6) FOR HX-202LR. THIS REPORT IS 4 OF 5 FOR PATIENT IDENTIFIER (B)(6) FOR UM-S20-20R.
