目的:结肠黏膜假性脂肪瘤病是一种罕见的良性内镜表现,具有明显的宏观和组织学特征。病例系列:我们在3个月内观察到8名患者出现了一种前所未有的结肠炎。操作员发现,在结肠镜检查期间,平坦或略微凸起的白色黄色斑块,在所有患者的结肠粘膜中。组织学检查结论为假性脂肪瘤病。经过调查,在此期间,发现消毒机在内窥镜的冲洗循环中出现技术故障。机器固定后没有观察到其他情况。结论:假性脂肪瘤病更多是内窥镜诱发的病变,而不是真实的病理状况。当检测到此类病变时,应仔细检查消毒过程。
假脂肪瘤病是一种罕见且无害的疾病,可发生在消化系统的各个部位。它看起来像扁平或略微凸起的白色或黄色斑块,与正常的肠道组织混合。在显微镜下,它表现为组织层中的空白空间。我们在3个月的时间里在结肠镜检查中发现了几例病例,可能是由内窥镜上使用的消毒剂引起的。发现这些病变应迅速仔细检查消毒程序。
Aim: Colonic mucosal pseudolipomatosis is a rare and benign endoscopic finding with distinct macroscopic and histological characteristics.
Case series: We observed a form of unprecedented colitis in eight patients in a 3-month period. Operators have found, during colonoscopy, flat or slightly raised whitish-yellow plaques, in the colonic mucosa of all patients. Histological examination concluded to pseudolipomatosis. After investigation, the
disinfectant machine was found to have technical malfunctioning of the rinse cycle of the endoscope during this period. No other cases were observed after the machine was fixed. Conclusion: Pseudolipomatosis is more an endoscopically induced lesion than a true pathological condition. A careful check of the disinfection process should be carried out when such lesions are detected.
Pseudolipomatosis is a rare and harmless condition that can occur in various parts of the digestive system. It looks like flat or slightly raised whitish or yellow patches mixed with normal gut tissue. Under a microscope, it appears as empty spaces in the tissue layer. We found several cases during colonoscopy over a 3-month period, likely caused by the
disinfectant used on the endoscope. Finding these lesions should prompt careful inspection of the disinfection procedure.
