Fig. 3 Images showing best practice technique for closure of the mucosotomy using through-the-scope clips: a the clip (short-dashed line) and mucosal incision (long-dashed line) are not in the same axis, with the clip needing to be rotated anticlockwise by angle θ to achieve optimal closure b the clip and the defect are in the same axis after repositioning of the clip (dash–dotted line) and the hilt of the clip is centered on the incision line; c good position of the closed clip, leading to edge eversion and symmetrical closure.
