Purpose. To repropose the importance of videofluoroscopy in the study of esophageal motor disorders, comparing the radiologic and manometric results: the manometric results are considered the reference parameters. Material and methods. From 1996 to 1999, 76 patients (42 males and 34 females), were studied first using manometry and then videofluoroscopy. The patients had symptoms like dysphagia, thoracic pain or both. The manometric study was performed with a perfusional system equipped with 6 tips (4 radial for the study of the esophageal sphincters and 2 placed longitudinally for the study of the esophageal peristalsis). With the patient in a supine position we analysed 5-10 deglutitions with 5 ml water bolus at 20-25°C, administered using a graduated syringe. The radiologic study was performed with a remote-control digital television system, connected to a video recorder. Three 7.5 ml bolues of high density barium suspension (250% weight/volume) were injected orally in the upright position and other three were injected in the prone position following the passage from the oral cavity to the stomach. Results. The comparison of the manometric and videofluoroscopic results suggests that the total sensitivity of the radiological study in the detection of esophageal motor disorders was 92%. In particular dynamic radiologic investigation diagnosed the normal esophageal functionality in 100% of the cases, nonspecific esophageal motility disorders in 89.6%, diffuse esophageal spasm in 100% of the cases, the presence of achalasia in 90%, whereas "nutcraker esophagus" only in 50%. Videofluoroscopy therefore showed high sensitivity in four groups of the five considered. It has some limitations in the diagnosis of initial achalasia, and is not sufficiently sensitive in the diagnosis of "nutcracker esophagus". Conclusions. Videofluoroscopy is a simple method which presents high sensitivity and specificity in the detection of motility disorders of the esophagus and could therefore be proposed as the first diagnostic method in patients with specific symptoms.
