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%.
所谓下咽憩室可根据其大小、位置和形态分为三个阶段。小型憩室（第一阶段）不应进行手术切除，而所有其他憩室，即那些引起症状的憩室，必须在诊断后尽快进行手术切除。一期憩室切除术是首选的治疗方法。回顾了一系列患者。发现手术风险较小，并发症发生率较低。在所有患者中，10%至12%可能出现放射学可显示的复发，而只有约2%出现复发的临床症状。
