BACKGROUND
There is little information on dilation of proximal strictures following surgical and/or radiation therapy for head and neck cancer. We studied the feasibility and efficacy of dilating proximal strictures following therapy for head and neck cancer using Savary Gilliard dilators.
METHODS
Twenty-one consecutive patients with proximal strictures resulting from surgery and/or radiation therapy of head and neck cancer were studied. Savary Gilliard dilation was performed using the standard and a modified method. Dysphagia was graded before and after dilation using a 5-point scale.
RESULTS
Technical success, dysphagia relief, complications, and duration of relief were noted. Technical success was achieved in 20 (95%) patients. Adequate dysphagia relief was obtained in 15/20 (75%) patients, which lasted for 4-36 weeks (median 14 weeks). There were no perforations, bleeding, or deaths. Four patients required repeat dilation after a median interval of 12 weeks.
CONCLUSIONS
Savary Gilliard dilation is a safe and effective method for dilating strictures caused by therapy for head and neck cancer.
背景
关于头颈部癌手术和/或放疗后近端狭窄扩张的信息较少。我们研究了使用Savary Gilliard扩张器对头颈部癌治疗后近端狭窄进行扩张的可行性和疗效。
方法
对21例因头颈部癌手术和/或放疗导致近端狭窄的连续患者进行研究。采用标准方法和改良方法进行Savary Gilliard扩张。扩张前后使用5分制对吞咽困难进行分级。
结果
记录了技术成功率、吞咽困难缓解情况、并发症及缓解持续时间。20例（95%）患者技术成功。15/20例（75%）患者吞咽困难得到充分缓解，持续4 - 36周（中位时间14周）。无穿孔、出血或死亡病例。4例患者在中位间隔12周后需要再次扩张。
结论
Savary Gilliard扩张是一种安全有效的对头颈部癌治疗引起的狭窄进行扩张的方法。
