title: Surgical experience of the national institution in the treatment of Zenker's diverticula.
abstract: OBJECTIVE
  To review the 8-year experience of the Department of Esophagogastric Surgery, First Surgical University Hospital in Belgrade in the surgical management of Zenker's diverticula (ZD).
  
  
  METHODS
  Between January 2000 and January 2009, 52 patients underwent surgical procedure for the treatment of ZD. Complete preoperative workup including the symptom evaluation and large variety of structural and functional diagnostic procedures were conducted before the surgery. After the operative treatment patients underwent detailed follow-up in regular intervals up to 3 years.
  
  
  RESULTS
  Preoperative evaluation marked higher incidence of hiatal hernia and pathologic gastroesophageal reflux (GER) among the patients with ZD then in normal population. According to the preoperative evaluation and size of diverticula, as well as due to the intraopertive findings, a variety of surgical procedures were performed, including myotomy alone (n = 2), diverticulopexy and myotomy (n = 36) and diverticulectomy and myotomy (n = 14). Regardless of the operative treatment no salivary cervical fistulas were observed. Late and early postoperative results revealed low incidence in postoperative transitory dysphagia or regurgitation.
  
  
  CONCLUSIONS
  The results of this study show that the open surgical procedures are safe and effective in the treatment of ZD. Cricopharyngeal myotomy remains the essential focus of treatment, while the choice of resecting or suspending the diverticulum is brought upon its size. Complete preoperative investigation must be conducted in ZD patients, and the role of pathologic GER must be taken into account when we discuss the origin of this disorder.
