肺中叶病变的诊断及外科治疗

Diagnosis and surgical treatment of the middle lobe lesions

作者对５２例肺中叶病变行外科治疗，其中支气管肺癌２７例，肺转移癌３例，错构瘤２例，良性病变２０例（支气管扩张６例，中叶综合征、结核各３例，炎性假瘤、肺动静脉瘘、肺大泡各２例，支气管结石、支气管肺囊肿各１例）。恶性肿瘤占５７．７％。中叶肺癌从发现病变到确诊时间平均为４个月，最长达１．５年。中叶肺切除占６７．３％，中叶部分切除或单纯肿瘤切除占１３．５％，中叶合并其它肺叶切除占１５．４％，右全肺切除占３．８％。作者认为中叶病变复杂，需综合分析方可作出正确诊断。特别指出中叶肺癌误诊率高，确诊不了的中叶病变应及时手术探查，中叶肺癌如能早期诊断及手术治疗，可彻底切除并多保留健康肺组织。

This paper presents 52 cases of the middle lobe lesions including primary bronchogenic carcinomas(27 cases),metastatic carcinomas(3 cases),harmatoma (2 cases)and the benign lesions (20 cases).The malignant tumors constituted 57 7%.The mean time was 4 months from finding the lesions to confirming the diagnosis of the middle lobe carcinomas.The surgical procedures employed included middle lobectomy in 67 3%,partle middle or simple tumorctomy in 13 5%,bilobectomy in 15 4% as well as right pneumonectomy in 3 8%.It has been emphasized that the disease of middle lobe is quite complicated.A correct diagnosis can only be made by analyzing the data obtained by a variety of combined examinations.Error of diagnosis of the middle lobe carcinomas was heigher.If it can been made the diagnosis and surgical treatment earlier,the health lung tissue will been preserved more.
