Innovative endoscopic techniques are attracting increasing attention as an alternative to surgery for early-stage colorectal cancer. One such alternative is endoscopic mucosal resection after endoscopic ultrasound (EUS).

In this video, Akahoshi et al. show the successful removal of a 7-mm, pT1b colorectal cancer (CRC) in the cecum using underwater endoscopic mucosal resection (UEMR) following EUS. However, before this technique can be considered for routine clinical practice, it must be further analyzed for efficacy, safety, and practicality.

Previous studies have shown that R0 resection rates for pT1b CRCs are lower using UEMR (40 %) [1] compared to endoscopic submucosal dissection (ESD) (65 %) [2] or endoscopic full-thickness resection (EFTR) (83 %) [3]. In addition, there is little available research on the safety of UEMR procedures. Finally, although UEMR may seem like a relatively simple procedure compared to ESD and EFTR, the technical challenge and difficulty of image interpretation when performing EUS should not be underestimated.
