RT Journal Article SR Electronic T1 Results of operative treatment of hypopharyngeal diverticulum. JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 544 OP 547 DO 10.1136/thx.31.5.544 VO 31 IS 5 A1 S Bertelsen A1 A Aasted YR 1976 UL http://thorax.bmj.com/content/31/5/544.abstract AB The so-called hypopharyngeal diverticula may be classified, according to their size, localization, and form, into three stages. Small diverticula (first stage) should not be surgically removed, whereas all other diverticula, that is, those causing symptoms, must be surgically removed as soon after diagnosis as possible. Diverticulectomy performed in one stage is the treatment of choice. A series of patients is reviewed. The risk involved in surgery is found to be of minor degree, and the incidence of complications is low. Radiologically demonstrable recurrence may develop in 10% to 12% of all patients while clinical symptoms of recurrence are seen in only about 2%.
