It has been noticed that patients undergoing major lung resection may occasionally develop dysphagia. A prospective study was carried out to evaluate if preoperative or postoperative esophageal motility disorders (EMD) occur in patients subjected to pneumonectomy for lung carcinoma. Twenty-five normal volunteers served as control data and 13 patients, who successfully completed manometry before and after pneumonectomy, were included in the final analysis. Studies were performed using a Gaeltec Model 6 ct/sb, 6-channel intraluminal strain gauge transducer probe. Our results demonstrated that EMD occurred in some patients suffering from lung carcinoma. However, motility disorders were most evident following pneumonectomy. These findings may explain the several anecdotal reports of patients developing dysphagia following lung resection after a variable interval of time.
