Adenomatous polyps of the appendix are rare [1] [2]; in some cases polypectomy is unsuccessful and surgical treatment is required [3]. Appendiceal polypectomy at colonoscopy is carried out extremely rarely [4]. This is the first reported case of an adenoma of the appendix resected using a traction device during endoscopy.
A 63-year-old man attended our hospital because of a positive fecal occult blood test. Colonoscopy provided a glimpse of the head of a polyp in the appendix, but it was difficult to visualize the whole polyp ([Fig. 1]). We fabricated a rubber strip-based traction device (modified S-O clip) [5] ([Fig. 2]), which we attached to the head of the polyp. A regular clip was used to grasp the distal nylon loop attached to the traction device, which was then inserted and applied to the colon wall opposite the lesion. The traction applied by the clip pulled on the head of the polyp and made the whole polyp visible ([Fig. 3 a], [Video 1]). Traction device-assisted endoscopic submucosal dissection (ESD), employing a HookKnife (Olympus Medical Systems Co., Tokyo, Japan) and electrocautery, was accomplished without complication after injection of a glycerol solution ([Fig. 3 b]). After ESD, the nylon loop was cut with the HookKnife. The resected specimen showed a subpedunculated polyp, 7 × 6 × 5 mm in size ([Fig. 4 a]). Pathological examination revealed a tubular adenoma ([Fig. 4 b]).

Quality:
In this case report we described successful ESD of an appendiceal polyp with a rubber strip-based traction device. We consider this type of traction device to be useful to resect appendiceal polyps.
