Abstract
BACKGROUND AND OBJECTIVE: The aim of this study is to analyze the impact on the cough after radical systematic mediastinal lymphadenectomy and prevention of refractory cough with mediastinal fat to fill the residual cavity after radical systematic mediastinal lymphadenectomy. METHODS: Sixty patients clinically diagnosed of lung cancer were selected according to the adopt standardization, from January 2008 to December 2008. All of the patients were divided into two groups randomly: the filling-fat group and the non-filling-fat group. The surgical information such as operation duration time bleeding volume during operation, post-operation bleeding volume were recorded. After one month, FACT-L and LCQ were completed. RESULTS: There are no remarkably differences between the operation duration time, bleeding volume in operation and 1st postoperation day's drainage volume of the two groups. There's significant difference in the scores of cough at night after taking off the chest tube, as well as in the scores of LCQ after one month and in the scores of last items of FACT-L. CONCLUSIONS: Filling the fat of the mediastinal to cover the residual cavity left by completely systematic mediastinal lymphadenectomy can reduce the refractory cough after surgery, and can also improve the quality of the life. It has no effect on the the operation duration time, bleeding volume in operation and 1st post-operation day's drainage volume of the patients.
