作者报告１９８６年７月～１９９３年３月胃癌切除术１５５例，无切端残留癌发生。作者体会避免切端残留癌应注意以下问题：（１）综合判断胃癌的生物学行为作为切除范围的依据；（２）术者亲自做胃镜病灶定位观察，了解癌缘到贲门、幽门的距离和胃体受累情况；术中做胃内导光透照观察辅助确定癌缘；（３）注意十二指肠的合理切除范围；（４）注意食管的合理切除范围；（５）胃体或累及胃体的进展期癌做全胃切除术；（６）需切除４ｃｍ以上食管者附加胸部切口或经胸手术；（７）考虑切端有残留癌可能，应对切缘做快速切片检查。
The authors reported 155 cases of gastric cancer resection from July 1986 to March 1993. There was no cut-off residual cancer. The author’s experience in avoiding cut-end residual cancer should pay attention to the following issues: (1) Comprehensively judge the biological behavior of gastric cancer as the basis of resection scope; (2) The surgeon personally do gastroscope focus observation to understand the distance from cancer edge to cardiac pylorus and stomach Involvement of the body; Intragastric light transillumination during surgery to assist in the determination of the cancer margin; (3) Pay attention to the reasonable range of resection of the duodenum; (4) Pay attention to the range of reasonable resection of the esophagus; (5) Stomach body or involving the stomach The advanced cancer of the body undergoes total gastrectomy; (6) Additional thoracic incision or transthoracic surgery is required to remove more than 4cm of esophagus; (7) Consider the possibility of residual cancer at the cut end, and perform rapid biopsy of the margin.
