Abstract

Background and study aim Endocytoscopy (ECS) is used in the in vivo microscopic inspection of microstructural mucosal features and enables endoscopists to assess the histological severity of ulcerative colitis (UC). The aim of this study was to assess histological healing in UC patients by using ECS. Patients and methods A total of 64 patients in clinical and endoscopic remission who underwent ECS were selected. The correlation between the ECS score and Geboes score at the rectum was evaluated in patients with a Mayo endoscopic score (MES) of 0.?The diagnostic accuracy of the ECS score for histological remission (Geboes score ≤?2) was also assessed. Results The ECS score ranged from 0 to 5 in patients with endoscopic remission on conventional white-light images (MES of 0). The agreement between histological remission regarding the ECS score and the Geboes score had a κ value of 0.72, and the ECS score showed high accuracy for histological remission, with a sensitivity of 0.77, a specificity of 0.97, and a diagnostic accuracy of 0.86. Conclusion ECS can be used to assess histological healing in patients with UC without the need for biopsy specimens.
