多原发性食管癌及食管胃双原发癌的诊断与治疗分析

为探讨如何提高多原发性食管癌及食管胃双原发癌的诊断率及生存率，对７８５例食管癌手术治疗患者的资料作了回顾性分析。结果：同时笥多原发性食管癌及食管胃双原发癌２３例，其术前诊断率３９．１％，其中食管钡透诊断率为１３％，胃镜诊断率为５０％，且异时性多原发性食管癌２例诊断亦由肋镜作出。

Diagnosis and Treatment of Multi-primary Esophagus Cancer and Esophagus-stomach Double Cancer

: To study how to increase the diagnosis rate and survival rate of the multi-primary esophagus cancer and esophagus-stomach double cancer. 785 patients with esophagus cancer treated by surgery were analyzed retrospectively. The results showed of the 785 patients 23 cases were diagnosed having synchronous carcinoma with the preoperative diagnostic rate being 39. 1 % (9/23), that of esophagogram being 13% (3/23), that of stomachoscopy being 50% (9/18), and 2 cases having metachronous carcinoma under stomachoscopy. It was suggested that the esophagogram and stomachoscopy were important methods for the improvement of preoperative diagnosis rate. Both methods could not be applied alone. The extensive esophagectomy and the careful histodiagnosis after operation can prevent the loss of diagnosis and the margin of resection from tumor.
