目的 :提高胰头癌侵犯门静脉和 (或 )肠系膜上静脉 (PV/SMV)的根治性切除率。方法 :对包括受侵的 PV/SMV在内的扩大的胰头十二指肠切除术 11例进行回顾分析。结果 :11例中有8例行血管壁部分切除 ,3例行血管节段切除 ,全组患者均未发生血管栓塞、肠坏死、肝衰竭等并发症 ,近期随访无 1例死亡和复发。结论 :对单纯侵犯 PV/SMV的胰头癌施行包括 PV/SMV在内的胰头十二指肠扩大根治术是可行的
Objective: To improve the radical resection rate of pancreatic cancer invading the portal vein and / or superior mesenteric vein (PV / SMV). METHODS: A retrospective analysis of 11 patients with enlarged pancreatoduodenectomy, including invasive PV / SMV, was performed. Results: In 11 cases, 8 cases were partially resected and 3 cases were performed resection of blood vessel. No complication of blood vessel embolism, intestinal necrosis and liver failure occurred in all the patients. No death or recurrence was found in the recent follow-up. CONCLUSIONS: It is feasible to perform extended pancreaticoduodenectomy, including PV / SMV, in patients with pancreatic head carcinoma that invades PV / SMV alone
