摘　　要：目的：探讨内镜微波凝固治疗晚期食管癌的有效性和安全限度。方法：选择晚期食管癌病人１０例，经电视内窥镜行微波凝固治疗，控制微波工作电流１１０～１２０ｍＡ，输出时间＜１５ｓ，５～７ｄ后手术切除癌肿，标本通过光镜和电镜检查。结果：经微波凝固治疗患者进食情况改善，取得满意的姑息性治疗效果。微波除对突入腔内癌瘤凝固气化外，仍对食管壁肿瘤组织产生杀伤，深度达４ｍｍ。结论：内镜微波凝固治疗晚期食管癌是安全有效的。Aim: To investigate the safety and effectiveness of the EMTC therapy for treating late esophageal carcinoma.Methods: Ten Patients of late esophageal carcinoma were selected and video EMTC therapy was performed under the following conditions: electric current from 110 to 120 mA and each output time within 15 sec.5～7days later,tumors were resected and the specimens were examined through fluorescence and electronic microscopy.Results: Patient's dysphagia conditions were improved obviously after EMTC therapy and satisfactory palliative effectiveness were obtained.Besides the tumors which projected into the esophageal cavity could be coagulated and evaporated,it could distroyed the tumor tissues which invated 4 mm depth into the esophageal wall.Conclusion: EMTC therapy for treating late esophageal carcinoma under video display obtained satisfactory palliative effectiveness and it is safe and effective.
