How to Address a Polyp Involving the Appendiceal Orifice

Polyps that involve the appendiceal orifice are currently unable to be fully removed safely colonoscopically as the appendix is unable to be removed with the specimen. Laparoscopic “radical appendectomy” or partial cecectomy has been shown to be a safe method for removing polyps that involve the base of the appendix. For large polyps >2 cm in size, intraoperative colonoscopic monitoring can be used to ensure negative margins following resection.
