内镜病理活检结合抗酸染色在诊断肠结核中的应用

Application of the Combined Technique of Biopsy via Endoscopy plus Acid-fast Staining in the Diagnosis of Intestinal Tuberculosis

为探讨内镜活检病理诊断肠结核的方法及抗酸染色的意义，对经抗酸染色证实的9例肠结核资料进行回顾性分析。结果显示，9例肠镜活检标本，在炎性渗出坏死或黏膜固有层内见上皮样微肉芽肿／上皮样细胞，抗酸染色均找到阳性杆菌。结果表明，在肠镜活检标本中出现上皮样细胞和（或）微肉芽肿时应考虑结核可能，必须行抗酸染色，抗酸染色对肠结核的诊断具有重要意义。

The clinical data of 9 patients with intestinal tuberculosis （TB） whose diseases were confirmed by acid-fast staining were analyzed retrospectively, so as to investigate the method of pathological diagno sing TB and the significance of acid fast staining. As results, epithelioid microgranuloma/epithelioid cells were found in the inflammatory exudate and necrosis or at the lamina propria mucous membrane of the nine biopsy samples via endoscopy,and TB bacillus was also found in acid-fast staining examination. It is suggested that whenever epithelioid cells and/or epithelioid microgranuloma are found in the biopsy sample, possibility of TB may exist,acid-fast staining is necessary to confirm its existence. Acid-fast staining is im portant in the diagnosis of intestinal TB.
