The purpose of this study was to retrospectively evaluate the severity and the characteristics of dysphagia using videofluoroscopic swallowing studies (VFSS) in long-lasting dysphagia patients developing after thoracotomy performed for pulmonary resection. Eleven patients (10 men and 1 woman, average age 67 ± 6.6 years; the average operation time in the patients was 507 min) were selected from among patients who developed dysphagia after undergoing thoracotomy for pulmonary resection between January 2009 and December 2012. The videofluoroscopic dysphagia scale (VDS) at 1 month postoperatively was used as a representative of parameters examined by the VFSS. The score on the functional oral intake scale (FOIS) was determined to evaluate the swallowing capacity at 1 and 3 months postoperatively. Most of the patients showed improvement of FOIS score at 3 months postoperatively. The patients showed mainly pharyngeal dysfunction. In spite of preserving the swallowing reflex, abnormalities of the residue in the vallecula and pyriform sinus and penetration were relatively frequent. Perioperative factors (age, %VC, FEV1.0 %, operation time, length of ICU stay) and FOIS were investigated to determine their relationships with the VDS score. While it showed no relationship with the age, lung function, operation time, and length of ICU stay, the VDS score was found to be significantly associated with the FOIS score at 3 months postoperatively. Evaluation by VFSS after lung surgery is useful to predict the prognosis of swallowing difficulty.
