Over-the-scope clip -assisted endoscopic full-thickness resection

- Over-the-scope Clip-Assisted Endoscopic Full-Thickness Resection of Duodenal Bulb Neuroendocrine Tumor. - Endoscopic full-thickness resection (EFTR) it allows for diagnosis and potentially definitive treatment of GI wall lesion. - Traditionally resection is performed first, followed by defect closure with over-the-scope (OTS) clips or endoscopic suture. - OTS clip-assisted technique allows address of the defect prior to full-thickness resection. - 70F with history of obesity and peptic ulcer disease presents 11 months following laparoscopic gastric sleeve. - Referred for upper endoscopy. - Duodenal mass biopsies consistent with well differentiated neuroendocrine tumor. - The patient elected for endoscopic resection. - Procedure tolerated without complication. - Patient was discharged to home from the PACU the same day. Final pathology: - Grade 2 Neuroendocrine tumor - Negative margins - 1X1X0.6 cm Instrument: Full Thickness Resection Device (FTRD System) produced by Ovesco AG (Germany).
