Underwater Endoscopic Mucosal Resection (UEMR) without injection for the resection of an adenoma located at the appendiceal orifice: a challenging approach

Abstract Text Underwater endoscopic mucosal resection (UEMR) has been recognized as a valuable technique for the en bloc resection of larger adenomas or flat lesions which are often more difficult to remove using traditional methods. The use of water for distension facilitates a better separation of the mucosal layer from the underlying submucosa. We present the case of a UEMR for the resection of a large adenoma located in the appendiceal orifice. By minimizing the distortions that can arise from air insufflation, water distension provided a clearer and more stable field of view. This enhanced, without using submucosal injection, the visualization of the lesion's edges, improving the ability to delineate the margins and ensuring that the resection includes the lateral and deep margins. No complications were observed [1] [2] [3] [4].
