Closure of post-EMR mucosal defects: to need or not to need, that is the question.

摘要

To the Editor:We read with interest the article by Fujii et al on a novel endoscopic suturing technique to close post-EMR large mu-cosal defects with a figure-of-8-shaped ring (8-ring) and clips. They previously described another method to close the defects with an endoloop and clips to prevent post-EMR delayed bleeding.Because the previous technique requires a double-channel colonoscope, they modified the technique to use a single-channel colonoscope, and they closed the defects successfully, without complications, in 10 lesions. We believe that this technique has some drawbacks, and furthermore, we doubt whether the prophylactic closure could effectively prevent delayed bleeding.
