“…Recently, another novel TTSC has been introduced -the dual action tissue (DAT) clip (Micro-Tech Endoscopy, USA, Ann Arbor, Michigan, USA). [9] This clip features two independent arms and is efficacious in closing large resection defects. It cannot be rotated so requires manipulation of the scope dials for positioning and operating the independent jaws can be difficult with endoscope looping.…”

Background & Aims: Endoscopic through-the-scope clips (TTSC) are used for hemostasis and closure. We documented the performance of a new TTSC with anchor prongs. Methods: We conducted a prospective case series of the new TTSC in 50 patients with an indication for endoscopic clipping at 3 hospitals in the USA and Canada. Patients were followed for 30 days after index procedure. Outcomes included defect closure and rate of serious adverse events (SAEs) related to the device or procedure. Results: Fifty patients had 56 clipping procedures. Thirty-four procedures were clipping after EMR in colon (33) or stomach (1), 16 after polypectomy, 2 for hemostasis of active bleeding, and 1 each for fistula closure, post-POEM mucosal closure, or anchoring a feeding tube. Complete defect closure was achieved in 32/33 colon EMR defects and 21/22 other defects. All clips were placed per labeled directions for use. In 41 (82.0%) patients, prophylaxis of delayed bleeding was reported as an indication for endoscopic clipping. There were 3 instances of delayed bleeding. There were no device-related SAEs. The only technical difficulty was one instance of premature clip deployment. Conclusion: A novel TTSC with anchor prongs showed success in a range of defect closures, an acceptable safety profile, and low incidence of technical difficulties.

“…Our group reported the first clinical experience with the DAT clip in various scenarios (i.e. mucosotomy closure after G‐POEM and defect closure in the colon and small intestine), with no adverse events encountered in the first nine cases 42 . More recently, we performed a multicenter prospective study demonstrating low delayed bleeding and high complete closure rate of mucosal defects with the DAT clip after endoscopic resection of large nonpedunculated colorectal lesions 43 .…”

“…The DAT clip catheter is 2.9 mm in width and requires a working channel inner diameter of 3.2 mm and above. The two arms of the DAT clip operate independent of each other, with an overall maximum opening width of 15 mm and 60° angle 42 . Independent opening and closing of each clip arm is controlled by color‐coded handles (Fig.…”

Third‐space endoscopy (TSE) is a subspecialty in interventional endoscopy that exploits the submucosa as a working space for the management of various gastrointestinal diseases. Over recent years, TSE has emerged as a viable alternative to surgery for the treatment of various conditions. The rapid dissemination and adoption of TSE has been largely supported by the advent of novel devices aimed to improve the efficacy and safety of these procedures. In this article, we review some of the recent developments in TSE devices and provide our initial experience with these instruments in clinical practice.
