A novel three traction rings device with endoscopic submucosal dissection (ESD) in the removal of a large superficial duodenal adenoma.

ABSTRACT

Endoscopic treatment is generally recommended for the duodenal epithelial adenoma. Although underwater endoscopic mucosal resection (UEMR) has become established as an effective modality for the superficial duodenal adenoma. However, it is difficult to completely remove a large superficial duodenal adenoma with en bloc resection. Endoscopic submucosal dissection (ESD) is commonly performed to remove a large superficial duodenal adenoma, whereas which is technically challenged with severe adverse events. It has reported that entire traction using clip-and-nylon ring with ESD was effective and safe in the removal of a large rectal sessile serrated adenoma (SSA). Herein, we shared our experience of the novel three traction rings device in the treatment of a large superficial duodenal adenoma.
