肺癌与食管癌术后乳糜胸的比较

目的：探讨肺癌术后乳糜胸（肺癌组）与食管癌术后乳糜胸（食管癌组）的临床特点。方法：回顾分析4084例肺癌术后12例,以及4479例食管癌术后52例乳糜胸的临床特点。结果：肺癌组术后乳糜胸的发生率为0.29％,食管癌组为1.16％。肺癌组术后4d内确诊4例,食管癌组为40例（77％）。肺癌组出现典型乳糜样胸水者占83.3％,而食管癌组为5.8％。肺癌组患者的临床症状及体征明显较食管癌组轻。肺癌组再手术率为16.7％,食管癌组为96.2％。本组所有病例均痊愈出院。结论：肺癌术后乳糜胸的发生率、病因、临床表现、诊断、及治疗与食管癌术后乳糜胸有明显不同。

Clinical features of postoperative chylothorax for lung cancer and esophageal cancer

Objective To define the clinical features of postoperative chylothorax for lung cancer(PCLC), and to compare them with those for esophageal cancer(PCEC). Method We retrospectively analysed clinical characteristics of 12 patients with chylothorax among 4 084 patients receiving resection of lung cancer, as well as 52 in 4 479 patients having resection of esophageal cancer since 1985 at our hospital. Results The incidence of PCLC was 0.29% and that of PCEC was 1.16%. The percentage of diagnosis confirmed within 4 postoperative days was 33.3% for PCLC, and 76.9% for PCEC. The rate of typical chylous pleural effusion was 83.3% for PCLC, and 5.8% for PCEC. Symptoms and signs of PCLC were much milder than those of PCEC. The re-operation rate was 16.7% for PCLC, and 96.2% for PCEC. All patients were discharged uneventfully. Conclusion The incidence, causes, clinical manifestations, diagnosis, and treatment of PCLC is different from those of PCEC.
