Transanal submucosal endoscopic resection (TASER) by TEO system®

Transanal submucosal endoscopic resection: a new endosurgical approach to the resection of giant rectal lesions.

a new endosurgical approach to the resection of giant rectal lesions Transanal surgical and advanced endoscopic resection procedures have the potential to provide complete and successful eradication of rectal lesions [1–3]. However, both approaches have limitations in terms of practicability and safety [3–5]. Transanal submucosal endoscopic resection (TASER) is a new endosurgical approach, whic...

Submucosal Endoscopic Tumor Resection

Transanal endoscopic microsurgery for the resection of submucosal and retrorectal tumors.

BACKGROUND Transanal endoscopic microsurgery (TEM) was originally designed for local endoscopic excision of benign and low-grade mucosal rectal lesions through an endoscopic system. The procedure is particularly challenging for submucosal and retrorectal lesions, as the tumor margins are not well defined. OBJECTIVE To investigate patient and surgical characteristics of TEM as a treatment for ...

Endoscopic Resection for Small Rectal Neuroendocrine Tumors: Comparison of Endoscopic Submucosal Resection with Band Ligation and Endoscopic Submucosal Dissection

Background and Aims. There is no consensus so far regarding the optimal endoscopic method for treatment of small rectal neuroendocrine tumor (NET). The aim of this study was to compare treatment efficacy, safety, and procedure time between endoscopic submucosal resection with band ligation (ESMR-L) and endoscopic submucosal dissection (ESD). Methods. We conducted a prospective study of patients...

Endoscopic resection of small-bowel submucosal nodule.

The options for management of submucosal nodules in the small bowel are limited. A 67-year-old woman presented for evaluation after positive findings from fecal immunochemical testing. Colonoscopy showed a 2-cm submucosal nodule in the terminal ileum. Superficial biopsies from the lesion were unrevealing. Over-thescope clip (OTSC)-assisted resection was planned. An OTSC (size 12/6, type gc) was...
