[Endoscopic full-thickness resection of adenoma in colon]

A new technique allows endoscopic resection of lesions (< 2.5 cm) as full-thickness resection from the gastrointestinal tract, primarily the colon. The technique is called endoscopic full-thickness resection (eFTR). This case report demonstrates the first eFTR in Denmark using an over the scope clip system. The eFTR was performed in two different cases, one with adenoma relapse and the other with incomplete endoscopic mucosal resection, both with success. Both patients were discharged the following day after eFTR. The histology of the tissue samples from the eFTRs showed no residual neoplastic tissue at the surgical margins.
