Microscopic colitis (MC) is a chronic inflammatory disease of the colon that presents with chronic, nonbloody watery diarrhea and only few or no endoscopic abnormalities. Histologic examination discriminates lymphocytic colitis (LyC; presence of ≥20 intraepithelial lymphocytes per 100 surface epithelial cells) and collagenous colitis (CC; colonic subepithelial collagen band >10 μm in diameter). MC not otherwise specified describes a subgroup of patients who do not fulfill the diagnostic criteria for either CC or LyC. Population-based epidemiologic data regarding MC are scarce. We aimed to evaluate the clinical presentation at diagnosis, incidence, and prevalence of MC in Cantons of Vaud and Fribourg, Switzerland.
显微镜下结肠炎(MC)是一种慢性结肠炎症性疾病,表现为慢性、非血性水样腹泻,仅有少数或无内镜下异常。组织学检查可区分淋巴细胞性结肠炎(LyC;每 100 个表面上皮细胞中存在≥20 个上皮内淋巴细胞)和胶原性结肠炎(CC;结肠黏膜下胶原带直径>10μm)。非特异性显微镜下结肠炎描述了一组不符合 CC 或 LyC 诊断标准的患者亚组。关于 MC 的基于人群的流行病学数据很少。我们旨在评估瑞士沃州和弗里堡州 MC 的诊断时临床表现、发病率和患病率。
