Core Tip
Core Tip: The aim of this study was two-fold: (1) To evaluate the safety and feasibility of the portable disposable large-channel endoscope for gastrointestinal examination and endoscopic submucosal dissection through animal experiments; and (2) To evaluate the quality of the endoscopic images, operational performance, and treatment efficiency. The results showed that the portable disposable large-channel endoscope can be used safely and effectively for gastroscopy and treatment.
