Core Tip

Core Tip: The local recurrence of colorectal adenocarcinoma that has been implanted deeply in the submucosal layers is usually missed by colonoscopy, despite that some cases show submucosal elevation. Endoscopic biopsies often give negative results, so endoscopic ultrasound fine-needle aspiration can be used to confirm the diagnosis and give patients a better chance for proper management.
