- In laryngectomized patients a tracheo-esophageal artificial fistula can be used to achieve air flow from the trachea to the esophagus during speech. A one-way plastic valve is often used for the fistula. A free jejunal graft between the trachea and the esophagus can also be used. To avoid aspiration the transplant is attached to the submental area giving the graft a siphon-like shape. We performed 23 videoradiographic examinations using high-density barium in 14 such patients. The aim was to evaluate the protective function of these grafts against aspiration. Penetration of the bolus and a small amount of residual contrast material in the ascending limb of the graft was a normal finding. If the standard barium bolus reached the descending limb at any time during the examination, this was a sign of aspiration hazard. To avoid aspiration, the vertex of the speech siphon should be higher than the level of the hypopharyngeal anastomosis.

- The aim of this study was to assess the role of videofluoroscopy in the detection of structural abnormalities of the pharynx and esophagus in patients with different symptoms of impaired deglutition. Dynamic radiographic recording of deglutition was performed in 3193 consecutive patients (1578 men, 1615 women; mean age 54 years) suffering from dysphagia, suspicion of aspiration, globus sensation, and non-cardiac chest pain. We assessed different structural lesions from the oral cavity to the esophagus and classified them into eight categories. Their frequency and association with the different clinical symptoms were evaluated. Videofluoroscopy revealed 1040 structural abnormalities in 833 patients (26%) including mass lesions from the oral cavity to hyoid/larynx (n=66), pharyngeal diverticula (n=181), pharyngeal masses (n=78), other pharyngeal narrowings (n=71), webs (n=98), masses (n=39), and other narrowings (n=73) of the upper esophageal sphincter, esophageal diverticula (n=80), esophageal webs, rings and strictures (n=194), and intrinsic and extrinsic esophageal lesions (n=160). There was a considerable variance of findings for different symptoms. In a large proportion of symptomatic patients videofluoroscopy detects morphological abnormalities along pharynx and esophagus often combined with functional disorders. This fact underlines the role of videofluoroscopy as a diagnostic test for function as well as morphology.
