Core Tip
Core Tip: Ileocecal laterally spreading tumors with appendiceal tubular adenoma are rare and hard to diagnose due to nonspecific symptoms. Traditionally treated by laparoscopic appendectomy, new research shows endoscopic submucosal dissection can be effective. This case innovatively applied sequential endoscopic submucosal dissection for high-grade dysplastic lesions at the appendiceal orifice, followed by appendectomy preserving the ileocecal valve. This approach improved postoperative quality of life and presents a novel strategy for deep-seated appendiceal lesions, addressing visualization challenges in deep lumen extension.
