Abstract
Background: Recurrent laryngeal nerve injury caused by esophageal cancer surgery is worrisome but often temporary; it is unclear when and how the paralysis is resolved. Hoarseness of voice from vocal cord paralysis (VCP) can have detrimental effects on postoperative patients. The aims of this study were to clarify the progress of nerve paralysis related to difficulty in talking after surgery and to assess whether hoarseness influences patient quality of life. Study Design: Between 1985 and 1996, 141 esophageal cancer patients undergoing a resection by the Akiyama procedure were cancer free 1 year after surgery. Among them, 51 patients with VCP on discharge from the hospital were retrospectively reviewed. Their VCPs, body weights, and pulmonary functions were examined yearly. They were given a questionnaire relating to the difficulty in talking 1 year after surgery. Results: VCP on discharge spontaneously healed within 1 year of surgery in 21 patients (41.2%), with the mean duration of difficulty in talking 5.7 months. The remaining 30 patients had persistent VCP 1 year after surgery; 4 VCPs spontaneously healed approximately 2 years after surgery. Eleven of the 30 patients with persistent VCP, who complained of severe hoarseness at 1 year postoperatively from inability to close the glottis during exertion, showed debilitation in performance status, abilities to go up stairs, and swallowing. In the group of patients with severe hoarseness, the percentage of ideal body weight (90.6% ± 11.0%) preoperatively and pulmonary functions at 3 years postoperatively were deteriorated, resulting in 3 patients with repeated aspiration pneumonia. Conclusions: The inability to compensate for aspiration, presenting as severe hoarseness, may be dependent on the preoperative nutritional state of patients along with degree of vocal cord atrophy and a decrease in pulmonary support. Persistent nerve paralysis deteriorates quality of life until it is adequately treated.
