Core Tip

Core Tip: Low-grade appendiceal mucinous neoplasms are a class of histologically well-differentiated adenomas. For low-grade appendiceal mucinous neoplasms with mass formation at the appendiceal orifice, if no metastatic lesion is indicated by imaging, the appendix and the mass at the appendiceal orifice should be completely resected. Our technique mainly targeted a mass approximately 1 cm from the opening of the appendix. We made the first pouch 1 cm from the root of the appendix, thus ensuring the anatomical integrity of the ileocecal valve. If conventional cutting closure is used, the anatomy of the ileocecal flap may be destroyed.
