分析５４例胃癌切除标本断端癌细胞残留（断端阳性）情况。认为降低术后断端阳性率可采取在施行胃贲门癌的近侧根治性切除或全胃切除时，食管切缘距肿瘤的距离≥５ｃｍ；暴露不充分时，可选择胸腹联合切口；十二指肠切除的范围要足够；还需考虑对胃癌生物学行为的研究；胃癌切除术应规范。
Analysis of 54 cases of residual cancer (residual positive end) in the cut end of gastric cancer resected specimens. It is considered that the reduction of the positive rate of postoperative severing can be taken when the proximal radical resection or total gastrectomy of gastric cardia cancer is performed. The distance from the esophageal margin to the tumor is ≥ 5cm; when the exposure is not sufficient, the combined thoracoabdominal incision can be selected; The range of duodenal resection should be sufficient; the study of the biological behavior of gastric cancer must also be considered; the resection of gastric cancer should be standardized.
