[Clinical analysis of postoperative recurrent nerve palsy in patients undergoing operation of carcinoma of the thoracic esophagus].
From January 1976 to April 1987, 325 cases of carcinoma of the thoracic esophagus were resected in our department. Among these cases, 25 cases were not included because of direct operative deaths or early hospital deaths, and 300 cases were selected for clinical analysis of postoperative recurrent nerve palsy, which occurred in 75 cases (25.0%). The rate of occurrence of this palsy in the last 6-year period was higher than that in the first 6-year period (34.0% and 15.3%, respectively). It was suggested that the extension of surgical procedures to the cervix and upper mediastinum had contributed to this increase in rate. The sides affected by palsy were as follows: left, 56.0%, right 12.0%, bilateral, 24.0%; unknown, 8.0%. The importance of gentle handling of the left recurrent nerve during operation should be emphasized. The rate of occurrence of palsy in the cases of "Iu" was higher than in cases of "Im" and "Ei" (53.3%, 31.6%, 26.8%, respectively). The rate of occurrence of this palsy was significantly higher in the cases in which cervical anastomosis was performed than in cases in which intrathoracic anastomosis was performed (31.9% and 2.8%, respectively; p less than 0.01). Of the cases complicated by this palsy (Group A), tracheostomy was done in 12.0% of the cases and long-term transnasal tracheal tube cannulation or tube reinsertion done in 29.3%. These rates were significantly higher than the rates for cases who did not develop this palsy (Group B). The rates of occurrence of postoperative pulmonary complications within one month after surgery in Group A and Group B were almost same (24.3% and 21.8%, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
