目的探讨普通内镜结合靛胭脂染色在鉴别瘤性与非瘤性大肠息肉中的价值。方法对124个大肠息肉分别行普通内镜及靛胭脂染色内镜诊断,若息肉表面呈沟槽状、脑回状或分叶状结构则定义为瘤性息肉,若表面光滑或有规则小圆点状小凹就定义为非...目的探讨普通内镜结合靛胭脂染色在鉴别瘤性与非瘤性大肠息肉中的价值。方法对124个大肠息肉分别行普通内镜及靛胭脂染色内镜诊断,若息肉表面呈沟槽状、脑回状或分叶状结构则定义为瘤性息肉,若表面光滑或有规则小圆点状小凹就定义为非瘤性息肉,并与组织学结果比较,比较2种内镜诊断方法鉴别瘤性与非瘤性大肠息肉的诊断准确率、特异性和敏感性。结果靛胭脂染色内镜鉴别瘤性与非瘤性大肠息肉的诊断准确率显著高于普通内镜(85.48% vs 70.16%,P<0.005)。染色内镜鉴别瘤性与非瘤性大肠息肉的敏感性和特异性分别为86.11%、84.62%,显著高于普通内镜的72.22%、67.31%(P<0.05)。结论普通内镜结合靛胭脂染色可较准确地鉴别瘤性与非瘤性大肠息肉,有助于实时指导内镜下对大肠息肉的处理方式。展开更多
坏疽性脓皮病(PG),一种罕见的、非感染性的中性粒细胞性皮肤病,常伴有其他全身疾病,其特征是疼痛性溃疡、边界模糊和外周红斑,其在溃疡性结肠炎(UC)患者中较为少见,是肠外表现的一种。本文将报道一例溃疡性结肠炎合并坏疽性脓皮病诊疗...坏疽性脓皮病(PG),一种罕见的、非感染性的中性粒细胞性皮肤病,常伴有其他全身疾病,其特征是疼痛性溃疡、边界模糊和外周红斑,其在溃疡性结肠炎(UC)患者中较为少见,是肠外表现的一种。本文将报道一例溃疡性结肠炎合并坏疽性脓皮病诊疗过程并进行文献复习,旨在提高临床医生对该疾病的认识以减少误诊、误治。Pyoderma gangrenosa (PG), a rare, non-infectious neutrophil skin disease often associated with other systemic diseases, characterized by painful ulcers, blurred boundaries, and peripheral erythema, is less common in patients with ulcerative colitis (UC) and is one of the extrenteral manifestations. This article reports a case of ulcerative colitis complicated with pyoderma gangrenosa and reviews the literature, aiming to improve the clinician’s understanding of this disease and reduce misdiagnosis and mistreatment.展开更多
