摘要
目的提高快速石蜡切片确诊率。方法选200例快速石蜡切片，通过与常规石蜡切片的诊断结果对照，对每例快速石蜡切片的诊断结果做出评价。分析误诊和未能确诊病例中取材不当的原因并提出纠正方法。结果200例快速石蜡切片确诊186例（93．0％），误诊5例（25％），未能确诊9例（4．5％）。误诊和未能确诊病例中由取材不当所致者10例（71．4％）。取材不当的原因为：①多成份肿瘤取材不全。②未发现隐匿病灶。③未取到良性肿瘤的恶变部位。④未取到受肿瘤侵犯的切线或淋巴结。⑤取材表浅，未达癌灶部位。③所取组织无法用于诊断。结论影响快速石蜡切片诊断的主要原因为取材不当。针对性取材，多点取材和协商取材是纠正取材不当的有效方法。
To raise the accurate rate of immediate paraffin section(IPS). Methods: Comparingwith routine paraffin sections, the diagnoses of 200 chosen cases of IPS werw evaluated and the causes of sampling er imaccuror were analysed in the inaccurate and uncertain cases. Results: The accurate cases were 186 (93 .0%), the inaccurate 5 (2.5%),and the uncertain 9 (4.5%) in 200 cases of IPS. The inaccurate and uncertain cases caused bysampling error were 10(71 .4% ). The canses of sampling or were:①incomplete sampling in multicomponent tu mor, ②neglecting the occult carcinoma, ③obtaining non-canceration tissues of a benign tumor, ④ sampling the nonsectional margin or lymph node not invasived by cancer, ⑤sampling too superficial to reach the cancer and ⑥the pling errors. Purposive sampling, multipoint sampling and consultaive sampling are effective measures for correctingcrrecting sampling errors.
