Event Description

Olympus reviewed the following literature titled "the use of endoscopic clipping in preventing delayed complications after endoscopic resection for superficial non-ampullary duodenal tumors".This retrospective cohort study described the use of endoscopic clipping in preventing delayed complications after endoscopic resection for superficial non-ampullary duodenal tumors.Patients were divided into 2 groups: the immediate clipping group (icg) and the no clipping group (ncg).Endoscopic mucosal resection (emr) and endoscopic submucosal dissection (esd) were performed using either twin-channel multi-bending gastroscopes (gif-2tq260m; olympus) or conventional gastroscopes (gif-h260 or gif-hq290; olympus).An initial incision was made outside the marks using either a dual knife (kd-655; olympus) or a hook knife (kd-620lr; olympus).After er, the mucosal defect was closed using clips (hx-610-090l; olympus ) delivered by a clip-fixing device (hx 110ur; olympus).A total of 99 lesions from 99 patients were included in this study.Fifty-two patients were allocated into icg and 47 patients were allocated into ncg.Delayed bleeding occurred in 1 patient from icg and in 8 patients from ncg.Delayed perforation occurred in 1 patient from icg and in 3 patients from ncg.There were no procedure-related deaths in both groups.This study concluded that although the use of endoscopic clipping seemed to reduce the risk of developing delayed complications, further studies using a prospective design is required.Type of adverse events/number of patients: delayed perforation (4), delayed bleeding (9), immediately complication (perforation n=1, bleeding n=5).The authors used six olympus devices and did not specify which device was used on the patients with adverse events.Patient identifier (b)(6): gif-2tq260m, we selected "gif-2tq260m" as a representative product.Patient identifier (b)(6): gif-hq290.Patient identifier (b)(6): kd-655l, we selected "kd-655l" as a representative product.Patient identifier (b)(6): kd-620lr.Patient identifier (b)(6): hx-610-090l.Patient identifier (b)(6): hx-110ur.This report is 4 of 6 for patient identifier (b)(6): kd-620lr.
