压片组织细胞学在术中病理诊断中的价值

An evaluation of squash preparation for intraoperative pathological diagnosis

手术中病理诊断要求准确而及时。目前主要是通过冰冻切片来完成。但由于冰冻切片机价格昂贵而许多中小医院尚未开展。在实际工作中我们发现压片法既快又准确，且又不需冰冻切片机，故很适合在基层医院开展。随机抽取１５４例术中送检组织进行压片诊断，结果与冰冻诊断一致者１３５例（８７．６６％）、不一致者１５例（９．７４％）、４例取材不当。在实践中不断总结，其准确率可逐步提高。

The practice of examining 'rapid' preparations of tissues at the time of surgery has grown up in parallel with the development of modern surgery. The use of cryostat sections for rapid diagnosis is popular, however,modern equipments and techniques are necessary. A simple and rapid diagnostic method, squash preparation, was performed on 154 cases for intraoperative pathological diagnosis. The results showed that 135 cases had the same diagnosis (87.66%) as in cryostat sections, and 15 cases had different diagnosis (9.74%).The other 4 cases could not obtain any diagnosis because of unsatisfied specimens. It is suggested that squash preparation with fine cellular detail and architectural features be of diagnostic value.
