Prophylactic appendiceal retrograde intraluminal stent placement (PARIS)
EMR or endoscopic submucosal dissection (ESD) are highly effective methods for resecting colonic polyps1-4 but are ineffective when removing polyps arising from the appendiceal orifice. Endoscopic full-thickness resection (EFTR) using the full-thickness resection device (FTRD; Ovesco, Tuebingen, Germany) is a favorable approach for the management of such lesions because it overcomes the potential risk of perforation or incomplete resection by deployment of an over-the-scope clip (OTSC) beneath the polyp before resection.Over-the-scope-clip treatment for perforation of the duodenum after endoscopic papillectomy
Endoscopic papillectomy is an alternative to surgery for tumors of the ampulla of Vater. Adverse effects of the procedure, however, include pancreatitis, bleeding, and papillary stenosis, as well as occasional perforations,1 which are sometimes challenging to treat endoscopically. A novel endoscopic closure device, the Over-the-Scope Clip (OTSC; Ovesco Endoscopy, Tübingen, Germany) System, has increased the ability of the therapeutic endoscopist to close gastrointestinal luminal defects and treat gastrointestinal bleeding.Full-thickness resection of subepithelial nodules, allowing for the diagnosis of an unusual case of pneumatosis cystoides intestinalis
A 61-year-old otherwise healthy man was referred to us for further evaluation of multiple firm, large, subepithelial descending colonic nodules. The area of nodularity was found incidentally on a screening colonoscopy and was located in the descending colon near the splenic flexure. The nodules extended over a length of 5 cm and varied in size from 1 cm to 2.5 cm. One nodule was sampled several times; however, examination of biopsy specimens revealed only colonic mucosa with inflammation and architectural distortion.Duodenal endoscopic submucosal dissection for a large protruded lesion located just behind the pyloric ring with a scissor-type knife
Recently, endoscopic submucosal dissection (ESD) has been applied to the treatment of GI lesions to enable en bloc curative resection.1,2 Generally, large tumor size, protruded lesion, poor endoscope maneuverability, and other procedural factors may contribute to the technical difficulties of ESD and periprocedural perforation.3,4 Among ESD procedures for GI lesions, duodenal ESD is the most technically challenging procedure because of the thin wall and narrow lumen of the duodenum, as well as poor maneuverability of the endoscope in the duodenum.Modified over-the-scope clip with telescope endoscopic full-thickness resection for colonic adenoma involving diverticulum
An 82-year-old man who underwent colonoscopy for iron-deficiency anemia was found to have a 15-mm polyp (Paris 0-IIa, type II NICE classification) involving the entire circumferential of the diverticulum in the distal descending colon. Biopsy specimens from this polyp revealed tubular adenoma with high-grade dysplasia. He was referred for endoscopic resection of this polyp (Video 1, available online at www.VideoGIE.org ).
