A series of 73 hypopharyngeal (Zenker's) diverticula is reported and the choice of treatment and technique of excision are discussed. The problems of excision include operation on an infected site with limited access but few patients are unfit for the procedure. Preoperatively the sac should be packed and the oesophagus stented. The side of approach is unimportant as the condition is essentially midline. Cricopharyngeal myotomy appears to reduce the recurrence rate, possibly by improving coordination of pharyngeal contraction and upper oesophageal relaxation. The use of electrocoagulation is not recommended as 20% of patients require repeated general anaesthesia and the procedure fails in 13%. For all but the smallest pouches, excision is the treatment of choice.
本文报告了73例下咽（Zenker氏）憩室病例，并讨论了治疗方法的选择及切除技术。切除手术存在的问题包括在感染部位进行手术，手术视野有限，但很少有患者不适合该手术。术前应填塞憩室囊并置入食管支架。由于病变基本位于中线，手术入路的选择并不重要。环咽肌切开术似乎可以降低复发率，可能是通过改善咽部收缩和食管上段松弛的协调性来实现的。不推荐使用电凝法，因为20%的患者需要再次全身麻醉，且该方法有13%的失败率。除了最小的憩室外，对于所有病例，手术切除都是首选的治疗方法。
