title: Zenker's diverticulum, a rare cause of upper gastrointestinal bleeding.
abstract: The most common complication of Zenker's diverticulum is aspiration pneumonia, compression of the trachea and esophageal obstruction with large diverticulum, and increased risk of development of carcinoma. Thus bleeding occurs rarely, can be massive and life threatening, with ulceration being the most common cause.
  
  
  METHODS
  We describe a patient with sever upper gastrointestinal bleeding as a result of a Zenker's diverticulum. A 75 year-old woman was referred to the emergency room and hospitalized for hematemesis, melena, asthenia and total dysphagia. In this particular case we preferred open technique because of the diverticulum dimensions and bleeding episode. Left cervicotomy was practiced on the anterior edge of the sternocleidomastoid muscle, being known that Zenker diverticulum extend into the left neck 90% of the time, fact also confirmed by radiology in this case.
  
  
  RESULTS
  Postoperatively, the patient showed a complication free recovery. Five days after treatment the patient resumed nourishment. Several days later our patient was able to return home. Follow-up at 12 months after the operation showed complete recovery. Ulcer of the basis of Zenker's diverticulum is a rare entity and, only a few cases were reported in the literature to date. Omitting thecricomyotomy predisposes to fistula or diverticulum recurrence due to the persistence of a high pharyngeal intraluminal pressure that acts on the posterior wall just proximal to the upper esophageal sphincter.
  
  
  CONCLUSIONS
  Zenker's diverticulum is an unusual site of origin for clinically significant upper gastrointestinal hemorrhage and differential diagnosis must include other more frequent causes of upper gastrointestinal bleeding. In our opinion, classicalsurgical therapy is indicated when distal esophageal imaging cannot be obtained during endoscopic examination, there is a large diverticulum or in an emergency setting when fast control over the bleeding source is required.
