PURPOSE: Swallowing disorders can be secondary to different types of diseases in which, at least initially, patients succeed in establishing voluntary or involuntary compensatory mechanisms that enable them to maintain a sufficient nutritional state. When the compensatory mechanisms become insufficient massive food aspiration into the airways can occur and suffocation may prove to be the main pathology. It has been calculated that in the USA about 8,000-10,000 people die each year due to suffocation. The dynamic radiological examination of swallowing is considered important not only for diagnosis, but also for planning a rehabilitation therapy and type of nutrition for the patient and for verifying the results of the therapy. The aim of this study is to analyse the results of our experience in the use of the digital cineradiography system to evaluate patients with normal and pathological swallowing. MATERIALS AND METHODS: We reviewed the digital cineradiography of 220 patients that at no time had undergone surgery and presented no organic pharyngeal or oesophageal disease (excluding hiatus hernia). All the exams followed a standard protocol that included the dynamic evaluation of the larynx, soft palate, pharynx, and gastro-oesophageal junction with a cineradiographic sequence of 12 frames/second with a 512x1024 matrix. There was also an archive of the film in a post-processing console. The patients received single photograms (printed on laserfilm), videotape recordings or CD-ROM of the dynamic exam. RESULTS: 137 (62%) of the patients did not present swallowing alterations although only 7 patients had a negative examination. In 35 cases hiatus hernia was appreciable while in 69 cases the hernia was associated with gastro-oesophageal reflux. In 23 cases aspecific functional disorders of the oesophagus were demonstrated and in 3 cases achalasia. The remaining 83 patients (38%) (37 males and 46 females, average age 57.02 yrs) presented alterations of the oral and/or pharyngeal stages of swallowing: reduction in soft-palate motility (2 cases), unilateral paralysis of the vocal chords (1 case), incontinence of the bolus during the oral stage (8 cases), lingual movement anomalies (4 cases), subepiglottic penetration (62 cases), asymmetric epiglottic tilt, aspiration of the contrast medium in the airway (17 cases), reduction of laryngeal and hyoid bone movement (9 cases), bolus retained in the valleculae and pyriform sinus (13 cases), cricopharyngeal spasm (6 cases), pharyngeal paralysis (1 case); hiatus hernia was also evident in 20 cases and gastro-oesophageal reflux was associated in 13 of them. Overall, 36% of the cases presented an isolated form while 64% of the cases presented a complex dysfunction with several simultaneous alterations. DISCUSSION AND CONCLUSIONS: The videofluorographic swallow study is an important step in the diagnostic evaluation of a dysphagic patient not only as regards the analysis of the main alteration and its capacity to confirm the presence or absence of contrast medium aspiration in the airway, but also because it provides important information on rehabilitation and nutritional orientation (oral/no oral), as well as on the results of the therapy. The recent diffusion of the digital X-ray equipment has made possible its use for the study of the organic and functional diseases of the upper alimentary tract. Currently a standard protocol for the study of swallowing with digital fluorography is not available. The technique we applied, already verified in a significant number of dysphagic patients, has allowed us to distinguish patients with normal swallowing from those with disorders of the oral and pharyngeal stage, and thus to identify disturbance and establish an appropriate rehabilitation treatment.
