联合门静脉／肠系膜上静脉切除的胰头癌根治术

目的探讨胰头癌侵犯门静脉（portalvein，PV）和（／或）肠系膜上静脉（superior mesentericvein，SMV）时根治切除的可行性。方法回顾分析11例PV／SMV受侵的胰头癌患者临床资料，均行扩大胰十二指肠切除术。其中7例行血管壁部分切除，3例行血管节段性切除及对端吻合，1例行受侵血管切除＋人工血管移植。脾静脉与SMV端侧吻合4例，脾静脉结扎3例。消化道重建采用Child术式。结果本组PV阻断时间平均为18．1（9～32）min。全组患者术后均未发生血管栓塞、肠坏死、肝衰竭等并发症，均康复出院。11例均获随访，时间6～20个月，3例术后1年内死亡，4例术后1—2年死亡，患者平均生存时间15（7～20）个月。结论对单纯侵犯PV／SMV的胰头癌施行联合PV／SMV切除的胰头癌扩大根治术是安全可行的。

Extended Pancreaticoduodenectomy Combined with Resection of the Involved Portal Vein/Superior Mesenteric Vein

Objective To explore the feasibility of radical resection for pancreatic head cancer involving portal vein(PV) and superior mesenteric vein(SMV).Methods The data of 11 cases with pancreatic head cancer involving PV/SMV underwent extended pancreaticoduodenectomy were analyzed retrospectively,including 7 cases of partial resection of the vascular wall,3 cases of segmental resection and end-to-end anastomosis,and 1 case of segmental resection followed by artificial graft transplantation.4 cases underwent end-t...
