One of the main difficulties during endoscopic submucosal dissection (ESD) is the
mobilization of the partially resected lesion in order to improve access to the lesion
edges and the dissection plane. In the current study, the feasibility and safety of
a new “yo-yo technique” to facilitate ESD procedures were evaluated. A total of 17
consecutive patients with gastric lesions were included. A standard hemoclip and snare
were used to pull and push the lesion margins in order to increase the access to the
lesion edges and to the submucosal space. All lesions were resected en bloc, without
perforation or significant bleeding requiring blood transfusion, and all patients
were discharged within 7 days. Resected specimens and lesions were 24 – 58 mm (mean
36 mm) and 18 – 45 mm (mean 25 mm) in size, respectively. The “yo-yo technique” is
feasible, easy, and safe, and allows the lesion to be pulled and pushed during the
ESD procedure. Further use of this technique may lead to the expansion of its indications
to other gastrointestinal regions.
