A 65-year old man suffering from dysphagia with aspiration was examined. ENT examination showed a Horner syndrome and cranial nerve palsy with paralysis of the soft palate and one vocal cord (palatolaryngeal hemiplegia, Avellis' syndrome). Pharyngeal manometry and videofluoroscopy depicted an asynergic swallowing with cricopharyngeal achalasia. CT scans of mediastinum, head, neck, and skull base showed no signs of abnormality. MR imaging of the brain stem demonstrated an enrichment of contrast medium in the dorsal region of the upper medulla oblongata in the level of the centre of the glossopharyngeal and vagus nerve. This case demonstrates an uncommon cause of dysphagia which was related to transitory brain stem ischaemia. After a period of three weeks the patients' complaints vanished as well as the clinical features. In a follow-up of MR-imaging three months later no focal enhancement of contrast medium was seen confirming the diagnosis of a brain stem ischaemic lesion.

For precise differentiation between organic and functional disorders of the oesophagus, the gastroenterologist makes use of radiology, endoscopy, and manometry, although a questionnaire may establish the final diagnosis in dysphagia with 95% accuracy. Combined therapy is gaining in increasing importance, such as dilatation of achalasia, bouginage of peptic strictures, implantation of prostheses and sclerosing of varices during endoscopy. For early diagnosis of carcinoma, close interdisciplinary cooperation between the ENT-specialist and the gastroenterologist is mandatory in panendoscopy of the squamous epithelium-lined aero-digestive system.

In the upper aerodigestive tract, carcinogenesis in squamous cell mucosa is characterized by a tendency to field carcinogenesis leading to multicentricity of lesions and synchronous or metachronous multiple tumoral lesions, namely multifocality. During pretherapy broncho-esophagoscopy carried out on ENT-cancer patients, the rate of synchronous second primary cancer is 24%. In 85% of the cases, these second primaries are detected at an early stage (in situ, microinvasive or submucosal carcinoma) and do not give rise to symptoms. Early diagnosis of cancer of the upper aerodigestive tract is possible provided that high risk patients are recognized and screening endoscopy of the whole mucosa is performed in every high risk patient. On the other hand, squamous cell carcinoma and adenocarcinoma may occur with increased frequency in patients with esophageal lesions such as achalasia, caustic stenosis and Barrett's esophagus. The premalignant potential of these three entities is discussed.

The primary cricopharyngealis achalasia (PCA) is a very uncommon functional disorder of the upper oesophageal sphincter (UES) characterized by dysphagia, frequent aspiration, and impaired relaxation of the UES. It should be differentiated from diseases of neuromuscular and ENT origin, from organic causes and other types of cricopharyngeal dysfunction. On suspected oesophageal inlet stenosis, swallow x-ray studies using water-soluble contrast material is performed, followed by oesophagoscopy. If the endoscope cannot pass into the oesophagus, balloon dilatation is performed to reach a diameter of 12-15 mm. This facilitates the passing of the endoscope and helps ruling out organic causes. If the stenotic segment dilates easily, the mucosa is intact, and no mechanical obstruction is discovered, then UES manometry is performed to differentiate from other motility disorders. Extraluminal causes are excluded using endosonography and CT. If PCA is diagnosed, low-pressure (1-1.5 atm) balloon dilatation is continued under fluoroscopic control until a lumen diameter of 18-20 mm is obtained. Efficacy of dilatation is assured clinically as well as with endoscopical, barium swallow and manometric studies. Five out of 28 patients with pharyngo-oesophageal dysphagia were found to have PCA. Patients presented with severe dysphagia and a predisposition to aspiration. The radiographic examination demonstrated stenosis at the UES level, and aspiration. It was possible to introduce the endoscope into the oesophagus only two of the five patients before the dilatation. The manometry was not pathognomonic, its value did not achieve the expectations. In contrast with organic stenoses, UES dilated easily using balloon catheter. Thereafter, the endoscope passed smoothly through the UES in each of cases. Following progressive dilatation--with low pressure (1.5-2 atm) up to 20 mm in diameter-, superficial mucosal damage was observed in one patient only. Patients' complaints ceased after treatment, and the barium swallow showed normal passage. Redilatation was necessary only in one case after following 21 (7-33) months. The authors supposed that the gastrooesophageal reflux plays role in the pathogenesis of PCA. Balloon catheter dilatation is an important diagnostic and at the same time effective, first choice, minimal invasive therapeutic method in PCA.

Swallowing disorders (dysphagia) comprise a common cause of medical consultation and are defined as a subjective sensation of difficulty or abnormality of swallowing. In the initial step, a clear differentiation of dysphagia from odynophagia and globus sensation for further diagnostic procedures is mandatory. The careful questioning of patients symptoms and complaints is often helpful for the differentiation of oropharyngeal and esophageal dysphagia. Oropharyngeal dysphagia is mainly caused by neurological disorders (cerebral ischemia, Parkinson's disease, dementia) or local compression of malignancies, thyroid gland or lymph nodes. In contrast, stenosis of the tubular esophagus (peptic stricture, rings and webs, diverticula, malignancies, infections) can lead to esophageal dysphagia, mostly only after ingestion of solids. Esophageal dysphagia after ingestion of solids and liquids is often caused by motility disorders of the esophagus (achalasia, hypertensive or hypercontractile esophagus). Important diagnostic procedures comprise endoscopy, barium swallow and high-resolution manometry. Overlap syndromes are frequent and need to be supervised interdisciplinary. The diagnostic algorithm and interpretation of exam results is complex. If the results are ambiguous, a reevaluation and, when appropriate, repetition of diagnostics are recommended. Whereas oropharyngeal dysphagia is treated by neurologists or ENT physicians, diagnostic and treatment of esophageal dysphagia is a challenging role for gastroenterologists.
