Surgical therapy of Zenker's diverticulum: low risk and high efficiency.

Surgery for the treatment of Zenker's diverticulum was performed at our institution in a total of 43 patients over 6 1/2 years. Cervical myotomy with diverticulectomy was performed in 32 of the patients and myotomy alone in 11. Mortality totaled 0%, with a reversible lesion of the recurrent nerve occurring in 7%. In 60% of the cases investigated preoperatively (N = 40), motility disorders of the upper esophageal sphincter (UES) could be demonstrated using manometry as well as with cineradiography in 92% of the patients. Follow-up studies in 39 of the cases 25 months (mean) postprocedure indicated 82% of the patients to be symptom-free, with the remaining 18% demonstrating a marked improvement. Postoperative manometry as well as cineradiography carried out in 12 patients revealed the presence of UES motility dyscoordination in 8% and 25%, respectively. There were, however, no signs of recurrence of the diverticulum. The high number of patients in our study group demonstrating motility disorders of the UES emphasizes the need for cervical myotomy as part of the surgical therapy for Zenker's diverticulum.     «
