Bone wax-tipped catheter and 3-way stopcock to optimize hemostatic powder deployment
TC-325 Hemospray (Cook Medical, Winston-Salem, NC, USA) is a highly absorptive mineral powder used for endoscopic hemostasis in the setting of nonvariceal upper GI bleeding. The hemostatic powder is propelled by compressed CO2 through either a 7F or 10F catheter inserted through the working channel of the endoscope.Endoscopic negative pressure therapy for upper gastrointestinal leaks: description of a fashioned device allowing simultaneous enteral feeding
Endoscopic negative pressure therapy (ENPT) represents a modern and effective treatment strategy for gastrointestinal tract wall defects. The intracavitary treatment strategy is based on placing a sponge within the defect cavity (Fig. 1), whereas the intraluminal treatment approach is based on placing a drainage device within the visceral lumen overlapping the defect area (Fig. 2).1 These strategies complement each other and are successful treatments for gastrointestinal perforation and postoperative adverse events in the upper or lower GI tract.Extrabiliary applications of fully covered antimigration biliary metal stents
Endoscopic stent placement in luminal GI strictures is not always feasible with traditional stents. For example, standard luminal stent delivery catheters may not successfully traverse severe strictures, and enteral stents may not be suitable for sites in the GI tract that pose significant adverse events if downstream migration were to occur. We demonstrate extrabiliary applications of specialized, fully covered antimigration biliary metal stents.Dynamic and multifocal clip and band countertraction for endoscopic submucosal dissection
Endoscopic submucosal dissection (ESD) is a challenging technique that bears a significant risk of perforation. Given that standard endoscopy, unlike laparoscopy, does not permit traction, the difficulty of ESD is augmented. Countertraction techniques have been shown to improve the speed of dissection, the rate of R0 resection, and the safety of the procedure.1-3Endoscopic submucosal dissection and submucosal tunneling endoscopic resection for obstructive lipomas of the foregut and hindgut
GI lipomas are rare, benign, submucosal tumors that are usually asymptomatic. The most common location for these lesions is the colon (64%), whereas duodenal lipomas account for only 4% of GI lipomas.1 Large lipomas (>2-4 cm) may cause symptoms such as bleeding, abdominal pain, obstruction, or intussusception.1-16 They typically present as a smooth, slightly yellow, rounded polyp, with a stalk or a broad-based attachment. Diagnosis can be confirmed by EUS, CT scan, or magnetic resonance imaging.“Posterior-like” anterior per-oral endoscopic myotomy
Per-oral endoscopic myotomy (POEM) can be performed by an anterior or a posterior approach to the esophageal wall, depending on the operator's preference. Recent data, however, show that posterior POEM is faster in accomplishing myotomy and in mucosal closure time, with less risk for inadvertent mucosal injury. These advantages are attributed to the axis of the dissection plane, which naturally parallels the endoscope working channel.
