    Abstract:
    Extended lymph node dissection in the neck and upper mediastinum often brings about postoperative pulmonary complications. Since September 1987, we have performed this type of lymph node dissection in 18 patients paying special attention to the preservation of tracheal proper sheath along with left bronchial artery and autonomic nerve branches. We compared their postoperative respiratory and circulatory outcomes with those of 17 patients in whom lymph node dissection was carried out without consideration for these aspects. Tracheal mucosal damage, respiratory functional parameters such as PaO2, AaDO2 and Qs/Qp and actual incidence of pneumonia significantly improved in recent cases undergoing meticulous dissection in the neck and upper mediastinum. However, neither circulatory dynamics nor incidences of recurrent nerve palsy and arrhythmia showed a significant improvement. The postoperative period required for reappearance of cough reflex was shorter in this group of patients, but the difference was not significant. The results indicated that pulmonary disorders occurring frequently after extended lymph node dissection for thoracic esophageal cancer was able to be well controlled by meticulous dissection procedure as mentioned above.
