针吸细胞学在肿瘤诊断中的应用,近年来发展迅速,很多基层医院已经开展,受到临床工作者的重视.我院1994年曾作24例体表肿瘤针吸细胞学检查,其中10例作了组织切片对照.良恶性基本相符.(一)针吸技术方法:针吸部位不需要麻醉,皮肤消毒后,医生戴手套,左手固定肿块穿刺部位,右手拿带8—9号针头的20ml注射器进入肿瘤内,进针时操作要熟练,注意避开血管及神经,抽吸物作涂片一张数张,待涂片自然干燥后,用95%酒精固定,HE染色,显微镜下观察.(二)针吸细胞学诊断:欲从小针头吸取物得到正确的细胞学诊断,首先必须熟悉镜下各种细胞形态学特点,认真细致观察并对疾病的临床表现有所认识,和掌握全身各个系统的各种肿瘤类型及瘤样病变,做到心中有数.(三)针吸细胞学临术应用:主要明确体表部位各种包块的性质,肿瘤非肿瘤及肿瘤的良恶性为临床治疗提供依据,如全身浅表淋巴结、乳腺、甲状腺、涎腺、软组织包块等,本方法操作简便,不需要特殊设备,节约开支,对患者损伤少,可及时得出结果.广大基层病理工作者可采用和推广.
The application of needle aspiration cytology in the diagnosis of tumors has developed rapidly in recent years. Many primary hospitals have been developed and have received attention from clinicians. In 1994, our hospital had performed 24 needle aspiration cytology examinations of surface tumors, including 10 cases of The tissue sections were compared. The benign and malignant were basically consistent. (1) Needle suction technique method: Needle anesthesia does not require anesthesia. After skin disinfection, the doctor wears a glove, the left hand fixes the lump puncture site, and the right hand takes a 20ml syringe with an 8-9 needle. Into the tumor, when the needle into the operation to be skilled, pay attention to avoid blood vessels and nerves, aspirates a smear a few, until the smear naturally dry, fixed with 95% alcohol, HE staining, observation under a microscope. ( B) Aspiration cytology diagnosis: To obtain the correct cytological diagnosis from a small needle, it is necessary to first familiarize with the various morphological characteristics of the cells, carefully observe and understand the clinical manifestations of the disease, and master the various systems of the body. A variety of tumor types and tumor-like lesions, to be aware of. (C) needle aspiration cytology Pro surgery applications: mainly to identify the nature of various masses on the body surface, non-tumor tumors and benign and malignant tumors provide clinical treatment Based on Table lymph nodes, breast, thyroid, salivary gland, and other soft tissue mass, this method is simple, requires no special equipment, save money, and less damage to the patient, the outcome can be timely. Grassroots workers employed pathology and promotion.
