Core Tip

Core Tip: This retrospective case-control study evaluated the diagnostic performance of the Japan Narrow-Band Imaging Expert Team (JNET) and pit pattern classifications for neoplastic lesions in patients with ulcerative colitis (UC). The JNET and pit pattern classifications did not show high accuracy in diagnosing the pathology and invasion depth of neoplastic lesions in patients with UC. Endoscopic diagnosis of UC-associated neoplasms tended to be underestimated when compared with pathological results. Endoscopic diagnosis of neoplastic lesions in patients with UC is still difficult, and treatment strategies need to be carefully determined.
