    Description of Event or Problem · 0

    OLYMPUS REVIEWED THE LITERATURE TITLED "RISK FACTORS FOR LYMPH NODE METASTASIS AND INDICATION OF LOCAL RESECTION IN DUODENAL NEUROENDOCRINE TUMORS". THE PRESENT STUDY AIMED TO INVESTIGATE THE CLINICOPATHOLOGICAL FEATURES OF DUODENAL NEUROENDOCRINE TUMORS (DNETS) WITH A RELATIVELY LARGE NUMBER OF CASES AND IDENTIFY THE RISK FACTORS FOR LYMPH NODE METASTASIS (LNM). IN ADDITION, SHORT- AND LONG-TERM OUTCOMES OF ENDOSCOPIC RESECTION (ER) AND LAPAROSCOPY AND ENDOSCOPY COOPERATIVE SURGERY (LECS) WERE COMPARED TO ESTABLISH THE APPLICATION OF LOCAL RESECTION FOR DNETS. 55 PATIENTS WITH 60 DNETS WERE ENROLLED; DNETS <5 MM WERE TREATED WITH ER AND THOSE OF 5¿10 MM WERE TREATED WITH LECS. LNM WAS PRESENT IN FOUR (8.7%) PATIENTS. NO SIGNIFICANT DIFFERENCES WERE OBSERVED IN TERMS OF COMPLICATION RATES. NO RECURRENCE WAS OBSERVED IN ANY OF THE GROUPS. TYPE OF ADVERSE EVENTS/NUMBER OF PATIENTS: [ENDOSCOPIC RESECTION GROUP (N=18)]. INTRAOPERATIVE PERFORATION- 2 PATIENTS. [LECS GROUP (N=9)]. ABDOMINAL ABSCESS- 1 PATIENT. THE AUTHORS USED 3 OLYMPUS DEVICES AND DID NOT SPECIFY WHICH DEVICE WAS INVOLVED WITH THE ADVERSE EVENTS. PATIENT IDENTIFIER (B)(6): GIF-Q260J. PATIENT IDENTIFIER (B)(6): KD-611L. PATIENT IDENTIFIER (B)(6): KD-650L. THIS REPORT IS 2 OF 3 FOR PATIENT IDENTIFIER (B)(6): KD-611L.
