SCAR-ENGAGED COLORECTAL LESIONS: ENDOSCOPIC SUBMUCOSAL DISSECTION (ESD) VERSUS A HYBRID RESECTION TECHNIQUE (ENDOSCOPIC UNSCARRING MUCOSAL RESECTION – EUMR)

Scar-engaged colorectal lesions are characterized by absent or inadequate submucosal lifting, posing a serious challenge for curative resection with need for surgery. We propose a hybrid resection technique that we called Endoscopic Unscarring Mucosal Resection consisting in marking, incision, partial dissection, creation of mucosal flaps and snaring until complete removal of the lesion (en bloc or piecemeal depending on...
