目的 减少和控制食管癌腔内放疗并发症的发生。方法 用两种方法,方法一治疗中、晚期食管瘤26例。方法二治疗中、晚期食管癌20例。两组病例腔内放疗参考点距离1cm。结果 两组病例食管炎发生率分别为38.5％及10％,差别显著(P<0.05)。食管瘘及食管穿孔大出血发生率无显著差别。 Objective To reduce and control the incidence of complications of endoluminal radiotherapy for esophageal cancer. Methods Two methods were used to treat 26 cases of advanced and advanced esophageal tumors. Method 2 treats 20 cases of advanced esophageal cancer. The distance between the two groups of intracavitary radiotherapy reference points was 1cm. Results The incidence of esophagitis in the two groups was 38.5% and 10%, respectively, with significant differences (P<0.05). There was no significant difference in the incidence of esophageal spasm and esophageal perforation.
