ICD was observed in 1.73% (n = 14) of all patients, including 11 (78.57%) men (aged 63.2\u2009\u00b1\u200912.95\u2009years [range 47\u201390\u2009years]) and three women (60.3\u2009\u00b1\u20094.04\u2009years [range 58\u201365\u2009years]). Most (63.16% [12\/19]) ICD lesions were localized in the sigmoid colon. And the diagnosis was confirmed by eversion using biopsy forceps in 78.95% of them.
