Event Description

Olympus reviewed the following literature "utility of underwater emr for nonpolypoid superficial nonampullary duodenal epithelial tumors =20 mm."     literature summary.This retrospective study analyzed the utility of underwater endoscopic mucosal resection for nonpolypoid superficial non-ampullary duodenal epithelial tumors =20 mm.A total of 132 patients (emr 21 patients 23 snadet, uemr 60 patients 61 snadet, emrc 45 patients 48 snadet) were included.For endoscopic resection, upper endoscope (gif q240z, gif q260j, gif h260z, or gif-h290t; olympus ) was used.For emr and emrc, saline and/or 10% glycerin solution (glyceol; chugai pharmaceutical ) with indigo carmine was administered for submucosal injection.For snaring of emr and uemr, a 10- to 20-mm electrocautery snare (maj-11, maj-216, snaremaster; olympus or captivator; boston scientific) was used.In emrc, a transparent cap (maj-291 or maj-296; olympus ) with an outer diameter of 14.8 or 16.1 mm was attached to the tip of the endoscope.A half moon braided snare (sd-7p-1; olympus) was used for snaring.Both uemr and emrc had a significantly higher r0 resection rate than emr.Uemr had significantly lower multiple resection and post-bleeding rates than emr.In terms of adverse events, only one (2.1%) patient who underwent emrc presented with intraoperative and postoperative perforation.Postoperative bleeding was defined as overt hematemesis, or a decreased hemoglobin concentration >2 g/dl after the procedure.Emr was involved in rx/1 and piecemeal resection.The recurrence rates of emr, uemr, and emrc were 4.3%, 2.0%, and 6.3%, respectively.This study concluded that the uemr had significantly higher r0 resection and lower post-bleeding rates than emr.Moreover, it was safer than emrc and was associated with a lower incidence of recurrences.The significant results of the retrospective analysis suggest a randomized controlled study with adequate numbers need to be conducted to confirm the superior efficacy of uemr before it is recommended for primary treatment option for snadet measuring =20 mm.The author responded to a request for additional information stating the adverse events were not caused by the olympus devices.Type of adverse events/number of patients endoscopic mucosal resection (emr): postoperative bleeding - 2 patients.Underwater emr (uemr): postoperative bleeding - 1 patient.Cap-assisted emr (emrc): postoperative bleeding - 1 patient.Intraoperative perforation - 1 patient.Delayed perforation - 1 patient.  this article includes 7 reports: patient identifier (b)(6):gif-q240z.Patient identifier (b)(6):gif-q260j or gif-h260z.Patient identifier (b)(6):gif-h290t.Patient identifier (b)(6):maj-11.Patient identifier (b)(6): maj-291 or maj-296.Patient identifier (b)(6): sd-7p-1.Patient identifier (b)(6): maj-216 wire.This report is 4 of 7 for patient identifier (b)(6):maj-11.
