METHODS： From January 1998 to December 2001, 73 patients with lower thoracic esophageal carcinoma underwent Ivor-Lewis subtotal esophagectomy with two-field lymphadenectomy. Clinicopathological information, postoperative complications, mortality and long term survival of all these patients were analyzed retrospectively. RESULTS： The operative morbidity and mortality was 15.1% and the mortality was 2.7%. Lymph node metastases were found in 52 patients （71.2%）. Nodal metastases to the upper, middle, lower mediastini and upper abdomen were found in 13 （17.8%）, 15 （20.5%）, 30 （41.1%）, and 25 （34.2%） patients, respectively. Postoperative staging was as follows： stage Ⅰ in 5 patients, stage Ⅱ in 34 patients, stage Ⅲ in 32 patients, and stage Ⅳ in 2 patients, respectively. The overall 5-year survival rate was 23.3%. For NO and N1 patients, the 5-year survival rate was 38.1% and 17.3%, respectively （X^2 = 22.65, P 〈 0.01）. The 5-year survival rate for patients in stages Ⅱ a, Ⅱ b and Ⅲ was 31.2%, 27.8% and 12.5%, repsectively （X^2 = 29.18, P 〈 0.01）. CONCLUSION： Ivor Lewis subtotal esophagectomy with two-field （total mediastinum） lymphadenectomy is a safe and appropriate operation for squamous cell carcinoma of the lower thoracic esophagus.展开更多
