- Abstract
Background and Aim Existing reusable endoscopic clip devices have some problems regarding opening the device and precise control of clip application. The aim of the present study was to evaluate reusable clip devices for endoscopic treatment. Methods Ability to close a large defect and grip force were evaluated using ex-vivo porcine colon. We assessed clip loading and opening in a non-clinical setting and describe the resulting learning curve. To evaluate clinical utility, data for clip application in 72 post-endoscopic mucosal resection ( EMR) defects in 40 patients were retrospectively analyzed. Results There was no difference in the ability to close a 20-mm full-thickness defect and the grip force comparing the new clip device ( ZEOCLIP®) and a previously used reusable clip device ( EZClip®). Although the time to load the ZEOCLIP was almost same as the EZClip, the time to open the ZEOCLIP was significantly shorter than the EZClip ( P < 0.001). Opening width of the ZEOCLIP was significantly wider than the EZClip ( P < 0.05). We successfully accomplished closure of post- EMR defects by clip application in 72 lesions using ZEOCLIP. Reopening/repositioning and restoring it to the working channel were more frequently carried out in a non-easy location than in an easy location (11/35 [31%] vs 4/37 [11%], P = 0.030; and 21/35 [60%] vs 1/37 [3%], P < 0.001, respectively). Conclusions ZEOCLIP is more quickly and easily opened to its maximum width compared with EZClip, and is feasible for clip application after EMR.
