目的 探讨喉裂开术中行冰冻病理检查诊断可疑喉癌的可行性、必要性和可靠性。分析喉癌病理诊断困难的原因。方法 32例病理诊断困难的喉癌病人,其中13例做过活检,但无阳性结果。采取不等待石腊固定切片的病理报告,直接在喉裂手术下取标本,进行冰冻切片检查确诊,而后行相应的手术。首次冰冻切片报告为阴性者,重复检查1次。结果 术中冰冻切片病理报告与术后病理报告一致者31例,占97.0％。不符合者只有1例。1例首次冰冻病理报告为阴性,经第二次检查纠正。结论 喉癌行病理检查困难,易于延误诊断。在术中进行冰冻切片做喉癌病理检查,结果可靠,可作为手术的依据。如首次检查为阴性,应进行重复检查。
Objective To investigate the feasibility, necessity and reliability of frozen pathological examination in the diagnosis of suspected laryngeal cancer by laryngectomy. Analysis of pathological diagnosis of laryngeal reasons. Methods Thirty - two patients with laryngeal cancer who had difficult pathologic diagnosis were biopsied, but no positive result was found in 13 of them. Take not wait for the paraffin fixed section of the pathological report, directly under the laryngeal surgery to take specimens, frozen section examination confirmed, and then the appropriate operation. The first frozen section of the report was negative, repeat the test 1 times. Results Intraoperative frozen section pathology report and postoperative pathology report consistent with 31 cases, accounting for 97.0%. Only one patient did not meet. One case of the first frozen pathological report was negative, corrected by the second examination. Conclusion The pathological examination of laryngeal carcinoma is difficult and delayed diagnosis. Frozen section in the operation of laryngeal pathology, the results are reliable, can be used as a basis for surgery. If the first test is negative, repeat the test should be carried out.
