【摘要】 目的探讨咽喉反流及胃食管反流在喉癌前病变及喉癌发生中的作用。方法2004年4月～2009年5月北京大学人民医院耳鼻咽喉科就诊并手术切除经病理确诊为声带黏膜不典型增生,经患者同意行24小时双探头pH监测(简称监测)的患者12例,1例喉鳞状细胞癌(T1N0M0)患者。结果13例患者监测,咽喉部pH阳性7例(53.85%),食管部pH阳性8例(61.53%),两者均阳性6例(46.15%),其中7例咽喉部阳性和8例食管部阳性的患者反流症状指数量表阳性均为5例,反流检查计分阳性均为6例。结论咽喉反流及胃食管反流可能是喉癌前病变和喉癌发生的危险因素之一。更多还原

【Abstract】 OBJECTIVE To study the effect of laryngopharyngeal and gastroesophageal reflux on the development of the laryngeal precancerous lesion and cancer.METHODS Twelve patients with vocal fold precancerous lesions and one patient with laryngeal cancer proved pathologically underwent 24-hour dual probe pH monitoring.All patients had been operated on and follow-up.RESULTS Seven of 13 patients(53.85%)showed positive pH monitoring in laryngopharynx,8 of 13(61.53%)patients showed positive pH monitoring in esophagus.Positive pH monitoring in both sites was found in 6 patients(46.15%).Among 7 patients with laryngopharyngeal reflux and 8 patients with gastroesophageal reflux,positive RSI was found in 5 cases and positive RFS was found in 6 cases.CONCLUSION The laryngopharyngeal reflux may be a risk factor in the development of the laryngeal precancerous lesion laryngeal cancer.更多还原
