Prospective feasibility study of a novel rigidizing stabilizing overtube in the resection of complex gastrointestinal polyps.

Background: A novel rigidizing overtube (ROT) was developed to facilitate endoscopic removal of complex gastrointestinal polyps. We aimed to prospectively evaluate the efficacy and safety of the device in the management of large gastrointestinal polyps.

Methods: A prospective, single-center study, conducted between May 2021 and April 2023, enrolled patients undergoing endoscopic resection of colon/duodenal polyps ≥25 mm.

Beyond boundaries: Feasibility of curved linear array echoendoscope in appendiceal neoplasm detection.

We recently read with great interest a study by Zhang in the W. In our practice, we focus specifically on examining appendiceal mucinous neoplasms (AMNs) with endoscopic ultrasound (EUS) using different scopes. AMNs are rare neoplastic lesions characterized by an accumulation of mucin inside a cystic dilatation of the appendix.
