Endoscopic resection of GI stromal tumor using full-thickness resection device: tips and tricks
Gastrointestinal stromal tumor (GIST) is the most common type of subepithelial lesion (SEL) in the stomach. Management of gastric GISTs varies by size. While all gastric GISTs ≥2 cm should be resected, the need to resect gastric GISTs <2 cm is still controversial given that surgical resection may be too aggressive for small, low-risk GISTs. On the other hand, evidence suggests that even <2-cm GISTs can metastasize.1 In fact, the Canadian guidelines suggest that even GISTs <1 cm should be excised because of the risk of metastases.Rare solitary giant hamartomatous polyp of the stomach removed by endoscopic submucosal dissection
The incidence of solitary gastric hamartomatous polyps (SGHPs) is extremely low, with fewer than 12 cases reported in the literature.1 Common symptoms include abdominal pain, bleeding, and anemia. While most SGHPs are benign, dysplastic changes have been reported.1,2 Hence, large lesions are typically referred for resection.1 In this video, we present a case of an SGHP resected with endoscopic submucosal dissection (ESD) (Video 1, available online at www.giejournal.org ).Endoscopic subserosal dissection for a GI stromal tumor
With the advancements in endoscopic resection techniques, subepithelial tumors (SETs) can be removed by transnatural orifice endoscopy with minimal invasiveness. Currently, available endoscopic procedures include endoscopic submucosal dissection, endoscopic submucosal excavation, endoscopic full-thickness resection, and endoscopic submucosal tunneling dissection, which have all been applied for SET management.1-3 Endoscopic subserosal dissection (ESSD) is a novel method for removal of SETs with origin beyond the muscularis propria layer in the upper GI tract.Hybrid resection of GI stromal tumor with endoscopic submucosal dissection and the full-thickness resection device
GI stromal tumors (GISTs) typically arise from the muscularis propria layer and are commonly seen in the stomach, although they can occur anywhere along the GI tract. Lesions larger than 2 cm should undergo surgical resection, although endoscopic resection can be considered for gastric GISTs 2 to 4 cm in size without high-risk features.1,2 Smaller lesions are monitored conservatively with surveillance EUS examinations, or endoscopically resected in patients who prefer to avoid frequent examinations.Use of helical tack system for management of a high-risk fibrotic peptic ulcer
GI bleeding because of peptic ulcer disease is a well-described entity in its diagnosis and management. Although hemostatic clips and thermal therapy have been the primary tools in bleeding from peptic ulcer disease, some bleeds remain refractory. New data have shown that obliteration of the underlying arterial blood flow is needed to control refractory peptic ulcer bleeding. Although this has been shown with over-the-scope clips, we present a case where GI bleeding is controlled via a helical tack system.Endoscopic rescue of anastomotic dehiscence after urgent gastric bypass revision
Adverse events are rare after bariatric surgery; however, leaks can lead to high morbidity. A large population study demonstrated a rare need for endoscopic management, most commonly endoluminal stent therapy. Unfortunately, many patients eventually needed surgical intervention and patients with stents had a notable rate of readmissions.1 Although stents are a valuable tool, newer technologies have expanded the toolbox to address difficult gastrointestinal adverse events.2,3 We present a challenging case of a gastrojejunal anastomotic disruption in a Roux-en-Y patient after recent urgent surgical revision that was rescued with total endoscopic therapy.Endoscopic management of gastrojejunocolic fistula after endoscopic gastrojejunostomy
Endoscopic ultrasound–guided gastrojejunostomy (EUS-GJ) is an alternative to endoscopic stent placement alone and surgical gastrojejunostomy for the management of gastric outlet obstruction (GOO). Similar technical and clinical success rates have been shown with EUS-GJ and endoscopic stent placement alone with lower rates of reintervention in the EUS-GJ group.1 When compared to the more invasive surgical GJ, EUS-GJ has shown similar rates of clinical success and lower adverse event rates.2,3 Rare EUS-GJ adverse events include perforation, peritonitis, bleeding, stent misdeployment, and migration.Endoscopic full-thickness resection of gastric ulceration with persistent low-grade dysplasia using full-thickness resection device
Endoscopic mucosal resection and endoscopic submucosal dissection (ESD) are well-established treatment methods for resection of precancerous gastric lesions and early gastric cancers.1 Ulcerated or scarred gastric lesions are challenging to resect with EMR or ESD because of submucosal fibrosis and scarring, and hence, carry increased risk for perforation.2
