The primary endpoint of the study will be to compare the accuracy of two procedures (FICE with target biopsies only, versus conventional white light colonoscopy with recommended targeted and random biopsies) in the endoscopic surveillance of patient with long-standing UC. Accuracy will be measured based on the number of patients with confirmed neoplasia using each technique. The combined histological outcome following the two procedures will represent the gold-standard diagnosis for each patient. Secondary outcomes will be the number of patients with false-positive findings, the number of neoplastic lesions detected, the number of false-positive lesions per patient for each technique and the total time required for each procedure.

Primary Outcome Measures:
  • The primary endpoint of the study will be to compare the accuracy of two procedures (FICE with target biopsies only, versus conventional white light colonoscopy) [ Time Frame: 3 months between FICE and Conventional white light colonoscopy ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The goal is to detect more and earlier neoplastic lesions in order to influence patient management in terms of treatment (potential colectomy) and surveillance. [ Time Frame: 3 months between FICE and Conventional white light colonoscopy ] [ Designated as safety issue: Yes ]
  • To quantify the number of true positive and false positive lesions by comparing the number of targeted biopsies performed for suspicious lesions and the resulting histological findings. [ Time Frame: 3 months between FICE and Conventional white light colonoscopy ] [ Designated as safety issue: Yes ]
