目的探讨胃癌切除术切端癌残留的原因及预防手段，减少癌残留的发生。方法回顾性分析我院１９８８年１月至１９９３年４月胃癌切除术切端癌残留３２例。结果胃癌切除术切端癌残留率７．４７％。上切端癌残留１１例，下切端癌残留１７例，上下端均有癌残留４例。根治性胃癌切除术癌残留率５．５％，姑息性胃癌切除术癌残留率１２．６１％，二者经统计学检验有显著差异。远、近端胃切除术切端癌残留率分别为５．８６％及１３．０％，统计学检验二者有显著性差异。癌残留与癌肿的大体类型、大小、分化程度及浸润深度有关（Ｐ＜０．０５）。结论浅表广泛型早癌，弥漫浸润型进展癌，癌肿直径＞５ｃｍ，分化程度低或不良，癌肿侵破浆膜者，易发生癌残留。术中切端冰冻活检，有助于减少胃癌切除术切端癌残留的发生率。
Objective To investigate the reasons and prevention measures of resected carcinomatous lesions of gastric cancer and reduce the occurrence of cancer residuals. Methods A retrospective analysis of 32 patients with residual cancer at the cut end from January 1988 to April 1993 in our hospital. [Results] The residual rate of resected cancer in gastric cancer was 7.47%. There were 11 cases of cancer at the upper end of the cut, 17 cases of cancer at the lower end of the cut, and 4 cases of cancer at the upper and lower ends. The residual rate of cancer in radical gastrectomy was 5.5%, and the residual rate of palliative gastric cancer was 12.61%. There was a statistically significant difference between the two methods. The residual rate of cancer at the distal and proximal gastrectomy was 5.86% and 13.0%, respectively. There was a statistically significant difference between the two groups. Cancer residue was related to the general type, size, differentiation and infiltration depth of cancer (P<0.05). Conclusions Superficial superficial early cancer, diffuse invasive advanced cancer, tumor diameter >5cm, low or poor differentiation, invasion of serosa by cancer, prone to cancer. Intraoperative frozen biopsies will help reduce the incidence of residual cancer in the resected cancer.
