INTRODUCTION:Between 1982 and 1989, 46 patients had insertion of an Angelchik prosthesis for gastro-oesophageal reflux. Eleven patients (24 per cent) subsequently had the prosthesis removed, all but one for intractable dysphagia.

METHODS:Thirty-six of the original patients were followed by questionnaire, and 32 of these had a barium marshmallow swallow investigation.

RESULTS:A high proportion of patients (20 of 26) with a prosthesis in situ had symptoms of dysphagia. On objective evaluation by marshmallow swallow, the transit time was significantly slower than that of an age-matched control group (P < 0.01), but showed no significant deterioration with time compared with previous postinsertion studies.

CONCLUSION:The Angelchik prosthesis causes long-term dysphagia in a high proportion of patients, severe enough in one-quarter to necessitate its removal. Its continued use cannot, therefore, be recommended.

简介 : 在1982至1989之间,有46例患者插入了用于胃食管反流的Angelchik假体。11名患者 (24%) 随后切除了假体,除一名患者外,所有患者均因顽固性吞咽困难。
方法 : 对36名原始患者进行问卷调查,其中32例进行了钡棉花糖吞咽研究。
结果 : 在原位假体的患者中,有很大比例的患者 (26例中的20例) 有吞咽困难的症状。在棉花糖吞咽的客观评估中,通过时间明显慢于年龄匹配的对照组 (P <0.01),但与先前的插入后研究相比,随着时间的变化没有显着恶化。
结论 : angelchik假体在很大一部分患者中引起长期吞咽困难,四分之一的患者严重到必须将其切除。因此,不建议继续使用。
