Caecal Laterally Spreading Tumour Involving The Appendiceal Orifice: the Challenges of Endoscopic Resection

A 78-year-old female, with no medical/surgical history, was referred because of a granular laterally spreading tumour (LST-G), NICE type 2, extensively involving the cecum and >50 % of the appendiceal orifice (AO), with deep extension in the appendiceal lumen.

Complete piecemeal endoscopic mucosal resection (EMR) was achieved using underwater cold snare and forceps avulsion techniques for the AO, followed by standard and underwater hot snare EMR of the remaining lesion. Histology revealed a low-grade tubulovillous adenoma.

We aim to discuss the challenges and techniques of EMR of LSTs involving the AO, as an alternative to full thickness resection or surgery.
