Abstract：
BACKGROUND: Zenker\'s diverticulum is an uncommon pathology of the upper oesophageal sphincter whose most frequent symptoms are the association of dysphagia and regurgitation. It is more frequent in advanced ages, and its treatment of choice is surgery in symptomatic cases.
METHODS: A retrospective descriptive study was performed of 27 patients operated in the Otorhinolaryngology service of the Hospital Universitario de Cabueñes between 2007 and 2019 using laser endoscopic surgery.
RESULTS: 27 patients were operated, 70.4% male and 29.6% female, with a mean age of 67 years (range between 30 and 91). The most frequent symptom at diagnosis was dysphagia. No intraoperative complications were observed. One patient (3.7%) presented post-surgical fever, and another patient (3.7%) had a serious complication due to oesophageal perforation secondary to postsurgical emesis. The median hospital stay was 5 days, and the median oral intake was 4 days. Recurrence was observed in 6 patients (22.2%), 4 (14.8%) requiring a second intervention, which was performed using the same technique.
CONCLUSIONS: The surgical treatment of Zenker\'s diverticulum has advanced in recent decades, with endoscopic treatment currently being the choice. Among the surgical options, endoscopic CO2 laser surgery is an effective and safe alternative, although possible complications must be considered. It is also an effective alternative for the treatment of recurrences.

摘要：
背景：Zenker憩室是食管上括约肌的一种罕见病理，其最常见的症状是吞咽困难和反流。它在晚期更频繁，在有症状的情况下，其治疗方法是手术。
方法：对2007年至2019年在Cabueñes医院耳鼻咽喉科服务机构使用激光内窥镜手术的27例患者进行了回顾性描述性研究。
结果：27例患者接受了手术，70.4%男性和29.6%女性,平均年龄67岁（范围在30到91岁之间）。诊断时最常见的症状是吞咽困难。术中无并发症发生。一名病人(3.7%)出现术后发热,另一名患者(3.7%)因术后呕吐继发食道穿孔而出现严重并发症。中位住院时间为5天,中位口服摄入量为4天。6例患者（22.2%）复发，4（14.8%）需要第二次干预，这是使用相同的技术进行。
结论：近几十年来，Zenker憩室的手术治疗取得了进展，内镜治疗是目前的选择。在手术选择中，内镜CO2激光手术是一种有效和安全的选择，尽管可能的并发症必须考虑。它也是治疗复发的有效替代方法。
