Novel single-operator through-the-scope traction device for endoscopic submucosal dissection: Outcomes of a multicenter randomized pilot ex-vivo study in trainees with limited endoscopic submucosal dissection experience (with video).

ABSTRACT:

Objectives

Endoscopic submucosal dissection is a technically demanding procedure. The pilot study aimed to prospectively evaluate the efficacy and safety of a novel single-operator through-the-scope dynamic traction device among trainees with limited endoscopic submucosal dissection (ESD) experience.

Methods

Randomized, controlled, pilot study comparing traction-assisted ESD (T-ESD) versus conventional ESD (C-ESD) in an ex-vivo porcine stomach model. Trainees were randomized to group 1 (T-ESD followed by C-ESD) and group 2 (C-ESD followed by T-ESD). Lesions were created on the gravity-dependent area of the stomachs. The primary outcome was submucosal dissection speed. Secondary outcomes included differences in en-bloc resection, adverse events, and workload, assessed by the
