[Myotomy (pars fundiformis m. cricopharyngei)in the treatment of Zenker's diverticulum. Report on 32 patients treated between 1972 and 1981].

11 patients were subjected to external operation with invagination of the pouch and myotomy; this procedure was chosen for younger patients, and small pouches with a broad spur. 21 patients were treated by cutting the spur of the diverticulum endoscopically; this intervention was preferred for older patients, and for larger diverticula with a narrow spur. Three of five recurrences were treated endoscopically. There were no complications, stay in hospital was short. Cutting the spur of the diverticulum relieves the cause of the patient's complaints. The endoscopic procedure can be repeated until satisfying results are obtained, even after previous external operations.
