背景:迟发性出血(DH)是胰十二指肠切除术(PR)后一种危及生命的并发症,死亡率非常高。然而,关于迟发性出血(DH)危险因素及预后影响因素的分析很少。方法回顾性分析熊本大学(Kumamoto University)1989年2月至2010年2月间共457例接受胰十二指肠切除术患者的资料。延迟性出血定义为术后第5天始出现的手术部位的出血,同时需要患者输入红细胞>2 U,以及接受强化治疗如剖腹手术、动脉栓塞术(TAE)或外科重症监护室治疗。根据人口学资 Background: Delayed hemorrhage (DH) is a life-threatening complication after pancreatoduodenectomy (PR) with very high mortality. However, there is little analysis of the risk factors for delayed bleeding (DH) and the prognostic factors. Methods A total of 457 patients undergoing pancreatoduodenectomy from February 1989 to February 2010 at Kumamoto University were retrospectively analyzed. Delayed bleeding is defined as bleeding from the surgical site that begins on day 5 postoperatively, requiring patients to enter red blood cells> 2 μ U as well as intensive care such as laparotomy, arterial embolization (TAE) or surgical intensive care unit treatment.
