本文报道我科１９７７年至１９８７年手术切除食管癌８７３例，术后切缘癌残留８８例，发生率为１０．１％。术后１、５、１０年生存率为７２．７％、１５．９％、９．２％。分析认为食管癌术后切缘癌残留的主要原因是食管切除长度不足，特别是胸中段食管癌。因此，应当切除足够长度的食管，行食管一胃颈部吻合术和术前放疗，以减少切缘癌残留的发生。 This article reports 873 surgically resected esophageal cancers in our department from 1977 to 1987. There were 88 cases of residual margin after surgery, and the incidence was 10.1%. The 1-, 5-, and 10-year survival rates were 72.7%, 15.9%, and 9.2%. According to the analysis, the main reason for the resection of esophageal cancer after surgical resection is insufficient length of esophageal resection, especially in the mid-thoracic esophageal cancer. Therefore, a sufficient length of esophagus should be removed, an esophageal-gastric neck anastomosis, and preoperative radiotherapy should be performed in order to reduce the occurrence of marginal cancer remnants.
