ObjectiveTo investigate the pathogeny,diagnosis,treatment and prevention of chylothorax.MethodsFrom February 2006 to June 2015 in our hospital 6 patients were retrospectively analyzed. There were 4 male and 2 female patients. The average age of the patients was 60(44--74)years old,the median age was 62 years old. 4 cases were lung cancer postoperative complications,1 case was esophagus cancer postoperative complications,1 case was trauma complication. Chyloliquid was 420ml--1500ml one day.Results3 patients were cured by conservative treatment,3 patients were cured by surgical treatment.ConclusionIf chylothorax can not be cured by conservative treatment,or chyloliquid was more than 1000ml one day,surgical intervention should be concerned. The surgical operation risk is little,the treatment period is short,and the results are satisfactory. It is worthwhile to select surgical treatment to cure chylothorax in clinical practice.%目的：探讨乳糜胸的病因、临床表现、诊断、治疗以及预防。方法回顾性分析2006年2月至2015年6月乳糜胸患者6例，其中男4例，女2例；年龄44~74岁，中位年龄62岁。肺癌术后并发4例，食管癌术后并发1例，外伤并发1例。乳糜液量420~1500ml/d。结果3例保守治疗获得治愈，3例手术治疗也获得治愈。结论乳糜胸经过保守治疗后不能治愈者，或乳糜液量>1000ml/d，采用手术治疗也可获得治愈，且手术风险小，疗程短，效果好，临床上值得推广。
