目的研究胃窦癌侵犯十二指肠具体长度,确定胃窦癌根治术中切除十二指肠的确切范围。方法选择有根治指征的胃窦癌患者行胃癌根治术,测定癌细胞侵犯十二指肠的长度,分析肿瘤浸润深度、大体形态、组织学类型、距幽门距离等与十二指肠浸润的关系。结果胃窦癌十二指肠浸润率可达51%,其浸润长度与浸润深度、Borrm ann型、肿瘤分化程度呈正相关,与距幽门距离呈负相关。结论浆膜受侵犯胃癌,Borrm annⅢ、Ⅳ型胃癌,低、未分化腺癌和印戒细胞癌,距幽门环近于1.5 cm的胃窦癌容易浸润十二指肠,手术切除十二指肠长度应大于3 cm。
Objective To study the specific length of the duodenum infiltrating the gastric antrum and determine the exact scope of resection of the duodenum. Methods The patients with gastric cancer who underwent radical gastrectomy underwent radical gastrectomy. The length of the duodenum infiltrating the cancer cells was determined. The depth of invasion, gross morphology, histological type, distance from the pylorus and duodenal infiltration relationship. Results The infiltration rate of duodenum in gastric antrum reached up to 51%. The length of infiltration was positively correlated with the infiltration depth, Borrm ann type, tumor differentiation degree and negatively correlated with the distance from the pylorus. Conclusion Serosal invasion of gastric cancer, Borrm ann Ⅲ, Ⅳ gastric cancer, low, undifferentiated adenocarcinoma and signet ring cell carcinoma, from the pyloric ring nearly 1.5 cm of gastric antrum easily infiltrating the duodenum, resection of the duodenum Length should be greater than 3 cm.
