Core Tip

Core Tip: Colorectal adenoma with submucosal pseudoinvasion has only been studied in a small number of small cases in the current national and international literature. At present, endoscopists diagnose our patient's lesion by electronic staining endoscopy (NBI), magnification endoscopy and ultrasound enteroscopy. A more accurate diagnosis of the depth of infiltration was obtained by pathological support. And if the pathologist misjudges, it will lead to overtreatment in clinical practice.
