Pretraction-assisted endoscopic submucosal dissection for the treatment of a rectal neuroendocrine tumor.

Abstract

Minor rectal neuroendocrine tumors (NETs) can be resected endoscopically using various procedures. Nevertheless, there remains controversy with regard to which of the possible endoscopic approaches is the most effective [1] [2] [3]. As revealed by relevant reports, endoscopic submucosal dissection (ESD) is an effective and safe technique for the treatment of rectal NETs; however, ESD requires physicians to have more surgical skills and operative times are longer than for other endoscopic resection techniques [2]. A pretraction-assisted ESD technique for small rectal NETs was therefore created to simplify the process and facilitate the operation ([Video 1]).
