Event Description

Olympus reviewed the literature titled: "indications for dental floss clip traction during gastric endoscopic submucosal dissection by less-experienced endoscopists." this retrospective study investigated the indications of dental floss clip (dfc) in endoscopic submucosal dissection (esd) performed by less-experienced endoscopists for early gastric cancer.A total of 812 patients were included.The procedure time in the dfc (+) group was significantly shorter than that in the dfc (-) group (95±46 vs.75±31, p<0.01).The procedure time for lesions located in the greater curvature of the upper or middle stomach and lesions >20 mm located in the lesser curvature side of the stomach in the dfc (+) group was significantly shorter than that in the dfc (-) group.Type of adverse events/number of patients: delayed bleeding - 30 patients, perforation - 10 patients.Delayed bleeding was defined as clinical bleeding after esd that required blood transfusion or endoscopic or surgical intervention.Perforation was diagnosed when mesenteric fat or intra-abdominal space was observed during the procedure or when free air was identified on simple chest and abdominal radiographs after esd.Related patient identifiers: (b)(6) - evis lucera gastrointestinal videoscope (gif-q260j).(b)(6) - disposable distal attachment (d-201-11804).(b)(6) - single use electrosurgical knife (kd-611l).(b)(6) - single use electrosurgical hemostatic forceps (fd-410lr).(b)(6) - rotatable clip fixing device (hx-110lr).(b)(6) - clip (hx-610-090).There is no report of any olympus device malfunction in any procedure described in this study.This medwatch is for patient identifier (b)(6).
