Abstract:
The aim of this investigation was to evaluate the efficacy of Japanese magnifying colonoscopic classifications for ulcerative colitis‐associated neoplasia ( UCAN ). Methods We reviewed the colonoscopy records from 2011 to 2018 at our institutions and identified cases of endoscopically or surgically resected UCAN observed by magnifying narrow‐band imaging ( NBI ) endoscopy and magnifying chromoendoscopy. Association between magnifying endoscopic classification and histopathological findings was investigated retrospectively. Japan NBI expert team ( JNET ) classification and pit pattern classification were applied. Results There were 17 patients who had a diagnosis of UCAN . Tumors of types 2A, 2B and 3 by JNET classification correlated with the histopathological findings of low‐grade dysplasia ( LGD )/high‐grade dysplasia ( HGD ), HGD , and massively submucosal invasive ( mSM ) carcinoma, respectively. Tumors of types III / IV , V I low irregularity, and V I high irregularity/ V N by pit pattern classification were correlated with the histopathological findings of LGD / HGD , HGD , and mSM carcinoma, respectively. Conclusions Japan NBI expert team classification and pit pattern classification may be predictive of the histological diagnosis and invasion depth of UCAN . This needs to be investigated prospectively in a large cohort or in a randomized clinical trial.
