超声内镜对食管癌治疗方式的术前评估价值

目的探讨超声内镜在食管癌的临床诊断上的应用价值以及对各种治疗方式的术前评估作用。方法内镜检查57例食管癌，了解癌肿的影像特征、浸润深度及癌旁淋巴结转移情况，并与术后情况进行比较。结果超声内镜显示肿瘤影像特征为不规则的低回声肿块伴部分或全部管壁结构的破坏，对肿瘤浸润深度诊断总符合率为84．2％（48／57），对T分期的诊断总符合率为87．7％（50／57）；对N分期的诊断总符合率为84．2％（48／57）。结论超声内镜对食管癌不同治疗方法的选择、手术方式的确定和预后的评估具有重要的参考价值。

Endoscopic ultrasonography in preoperative assessment of esophageal cancer

Objecfive To explore the value of endoscopic uhrasonography(EUS)in diagnosis and preoperative assessment of esophageal cancer.Methods A total of 57 patients with esophageal cancer were examined by EUS.The image features,depth of invasion and lymph node metastasis obtained by EUS were analyzed and compared with postoperative outcomes.Results Esophageal cancer was characterized as an irregular hypoeehoic mass with partial or total destruction of normal esophageal wall structure under EUS.Compared with post-operative pathological findings,the consistent rates of EUS diagnosis in depth of invasion,T staging,and N staging were 84.2%(48/57),87.7%(50/57)and 84.2%(48/57),respectively.Conclusion EUS exhibited high diagnostic accuracy in T staging of esophageal cancer,which is valuable in managements and prognosis of esophageal cancer.
