However, the endoscopic diagnosis of UCAN is occasionally challenging and requires a stepwise approach using multiple endoscopic modalities. The worldwide consensus is that a diagnosis of high-grade dysplasia or higher is an indication for proctocolectomy. Although the management of low-grade dysplasia (LGD) remains controversial, the SCENIC consensus statement recommends the complete removal of \"endoscopically resectable\" LGD, followed by monitoring. ESD was developed in Japan, allows for the removal of complex gastrointestinal lesions, facilitates the treatment of LGD, and enables precise pathological evaluations to differentiate between UCAN and sporadic tumors and to determine the grade of dysplasia in UCAN. Close endoscopic surveillance should follow complete endoscopic resection.

In terms of gut bacteria, microbiome diversity decreased significantly while mycobiome diversity increased, along with the enrichment of harmful microbiota and shrinkage of probiotic microorganisms. Therefore, the data suggested that TNBS-induced CD can be roughly divided into two phases: the acute inflammatory phase (weeks 1 to 2) and the chronic inflammatory phase (weeks 3 to 5).
