[Endoscopic full-thickness resection of residual colonic adenoma with fibrosis].

Endoscopic fullthickness resection is a technique that allows in block resection of colonic lesions in patients in whom conventional endoscopic methods such as endoscopic mucosal resection or endoscopic submucosal dissection have failed. We present a case of a 75-year-old man with history of a difficult-to-resect colon adenoma. He had undergone two previous failed attempts of endoscopic mucosal resection due to non-lifting sign in another center. We successfully performed an endoscopic full-thickness resection procedure, avoiding unnecessary surgery.
