Traction devices can make it technically easier. In this study, we evaluated a flexible grasper with articulating tip and elbow-like bending (IgE) through a double-balloon surgical platform (DESP), compared with an earlier generation grasper without elbow-like bending (Ig). The reach of Ig\/IgE was investigated at eight locations using a synthetic colon within a 3D model. Using a fresh porcine colorectum, 4\u00a0cm pseudo-polyps were created at the posterior wall of the ascending colon. Fifty-four ESD procedures were performed using three techniques: standard ESD (STD), ESD using Ig (DESP\u2009+\u2009Ig), and ESD using IgE (DESP\u2009+\u2009IgE). IgE was able to reach the full circumference at all the locations, whereas the medial walls proximal to the descending colon were out of Ig\u2019s reach. Compared with the STD, both DESP\u2009+\u2009Ig and DESP\u2009+\u2009IgE showed significantly shorter procedure time (STD vs. DESP\u2009+\u2009Ig vs. DESP\u2009+\u2009IgE\u2009=\u2009median 48.9\u00a0min vs. 38.6 vs. 29.9) and fewer injuries (1.5 vs. 0 vs. 0). Moreover, the DESP\u2009+\u2009IgE had a shorter procedure time than the DESP\u2009+\u2009Ig (p\u2009=\u20090.0025). The IgE with DESP increased instrument reach compared to Ig, and likely represented a traction tool for excision of large pseudo-polyps in the right colon.<\/jats:p>","DOI":"10.1038\/s41598-021-98162-x","type":"journal-article","created":{"date-parts":[[2021,9,21]],"date-time":"2021-09-21T06:22:28Z","timestamp":1632205348000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Use of an endoscopic flexible grasper as a traction tool for excision of polyps: preclinical trial"],"prefix":"10.1038","volume":"11","author":[{"given":"Shinya","family":"Urakawa","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teijiro","family":"Hirashita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuka","family":"Hirashita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lea","family":"Lowenfeld","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krishna C.","family":"Gurram","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Nishimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey W.","family":"Milsom","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,9,21]]},"reference":[{"key":"98162_CR1","doi-asserted-by":"publisher","first-page":"405","DOI":"10.1111\/den.12597","volume":"28","author":"N Patel","year":"2016","unstructured":"Patel, N. et al.
