Core Tip

Core tip: Mucosal healing has been recognized as the treatment goal of ulcerative colitis (UC). Although many previous reports defined mucosal healing as Mayo endoscopic subscore (MES) of 0 or 1, the difference in prognosis between patients with MES 0 and those with MES 1 has scarcely been evaluated. This paper indicated that the relapse rate differed greatly between patients with MES 0 and MES 1, and that the treatment goal of UC should be MES 0. We also demonstrated that a shift from MES 0 to MES 1 in clinically stable UC patients can be predicted by monitoring platelet count.
