目的探讨应用电化学疗法治疗中晚期食管癌和贲门癌的临床疗效。方法电化学疗法治疗中晚期食管癌和贲门癌４２例，对其治疗前后的疗效进行比较。结果通过对比电化学治疗前后食管Ｘ线钡餐检查及进食改善情况显示，８８％的患者在接受电化学治疗后进食明显改善，８９％的患者食管狭窄扩大在０．５ｃｍ以上。结论电化学疗法治疗食管癌和贲门癌解除食管梗阻见效快，疗效显著，能恢复患者饮食，可为实施其他治疗创造条件，使其远期生存率提高。
Objective To investigate the clinical efficacy of electrochemotherapy in the treatment of advanced esophageal and cardiac cancers. Methods Electrochemotherapy was used to treat 42 cases of advanced esophageal and cardiac cancers. The curative effects before and after treatment were compared. Results The comparison of esophageal X-ray barium meal examination and eating improvement before and after electrochemical treatment showed that 88% of the patients had significantly improved their food intake after receiving electrochemical treatment, and 89% had an esophageal stricture extending more than 0.5 cm. Conclusion Electrochemotherapy for the treatment of esophageal and cardia cancers can relieve esophageal obstruction with rapid effect and significant curative effect. It can restore the diet of patients and can create conditions for the implementation of other treatments and increase the long-term survival rate.
