title: [Zenker's diverticulum--diagnosis and therapy].
abstract: Clinical, x-ray and endoscopic follow-up of patients operated on for Zenker's diverticulum (pharyngo-oesophageal diverticulum) via myotomy and diverticulectomy permits conclusions in respect of functional results of this therapeutic concept and the preoperative diagnosis that our study has proved to be necessary. Usually the diagnosis can be made on the basis of the characteristic anamnesis. It is confirmed by means of an oesophagogram, if necessary with a gastrointestinal passage. Besides visualisation of Zenkers diverticulum, attention must be paid especially to associated neuromuscular functional disturbances of the oesophagus. Preoperative endoscopy is necessary in individual cases only. In respect of therapy, it appears mandatory to perform a sufficiently extended (3-5 cm) myotomy of the pars transversa musculi cricopharyngei because of the frequently seen disturbance of coordination of the pharyngo-oesophageal sphincter, besides removing the diverticulum.
