Endoscopic ultrasonography in preoperative assessment of esophageal cancer / 中华消化内镜杂志

ABSTRACT

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.
