BACKGROUND: Pharyngoesophageal diverticulum presents itself as an uncommon disorder. Thus, choosing the most effective treatment method may be challenging. Surgical treatment remains as the main option. However, establishing the best surgical technique is still controversial. AIM: To evaluate the results of diverticulecomy with chricopharyngeal miotomy and linear stapler closure of the pharynx in a patient sample with Zenker`s diverticulum regarding local and systemic complications. METHODS: Nineteen patients with pharyngoesophageal diverticulum were admitted. All of them presented the clinical conditions required to indicate the surgical procedure. Patients were evaluated with regard to any post-operative complications. This study was conducted retrospectively with patients' data analysis. RESULTS - Patients showed satisfactory results, with no evidence of fistula at the level of the pharyngeal suture. Two out of 19 lost post-operative follow-up and one of them had pharyngeal stenosis reverted with endoscopic dilation. The entire sample reported being satisfied with the procedure emphasizing improvement of the quality of life mainly due to the return of physiological deglutition. CONCLUSION: The diverticulectomy with myotomy and posterior pharyngeal closure with linear surgical stapler proved to be an effective technique, offering a lower risk of post-operative complications and improving the overall quality of life.
