[Achalasia of the oesophagus; early and late results of dilatation and surgical procedures (author's transl)].

Till now etiology and pathogenesis of achalasia of the oesophagus are unknown. The disease is based on dysfunction of the lower oesophageal sphincter. Early and late results of dilatation and surgical procedures are compared. This review deals with 57 operated patients and 102 dilatated ones (Starck's Dilatator). Late results--25 operated and 22 dilatated patients were evaluated on an average at 9.5 or 8.3 years respectively. In the early stage of achalasia 2 to 3 dilatations are recommended. A cardio-myotomy combined witha fundoplication should be performed in high-graded stenoses and after unsuccessful dilatation.
