The colonoscope shaft loop can be unwound by establishing a loop in the universal cord of the colonoscope to maintain the same endoscopic view during colorectal endoscopic resections.

Keywords: endoscopic colorectal resections, endoscopic mucosal resection, endoscopic submucosal dissection, polypectomy

1. INTRODUCTION

Endoscopists must rotate the endoscope to bring the lesion closer to the forceps hole (typically in a 5–6 o'clock direction) while performing endoscopic colorectal resections. 1 , 2 During this process, a loop is sometimes created in the colonoscope shaft and the endoscopist's hands frequently need to maintain the loop to keep the same endoscopic view, making free hand movement difficult.

Unwinding the colonoscope shaft loop via the universal cord can be used for colorectal endoscopic treatment, such as colorectal endoscopic resections, because it frees the endoscopist's hands while maintaining the same endoscopic view during colorectal endoscopic resections (Figure 1, Video 1).

Colonic polypectomy case depicting the unwinding usage of the colonoscope shaft loop via the universal cord. Polyp of macroscopic type 0–Is, 5 mm in size, and located in the proximal ascending colon; arrow indicates the polyp. (A) Endoscope must be rotated counterclockwise to bring the polyp to the 5 o'clock direction, restricting the endoscopist's hand movement. (B) After unwinding the colonoscope shaft loop via the universal cord, the polyp remains in the 5 o'clock direction; however, the endoscope returns to a neutral position, enabling free hand movement.
