目的探讨保留肝动脉血供的肝血流阻断对肝切除术失血量和肝功能的影响。 方法回顾性分析了2007年9月至2012年12月期间上海交通大学医学院附属第三人民医院118例行肝切除术患者的临床资料，其中68例行保留肝动脉血供的肝血流阻断（保留组），50例采用Pringl法行肝门阻断（阻断组），比较2组的手术失血量、接受输血病例的比例、手术并发症以及术后肝功能恢复情况。 结果全组无围手术期死亡病例。保留组患者的平均手术时间、术中失血量、接受输血患者的比例、术后肠道功能恢复时间以及术后并发症发生率与阻断组相比差异均无统计学意义（P＞0.05）；术后第1天及第5天，谷丙转氨酶及谷草转氨酶水平保留组明显低于阻断组（P＜0.05）。 结论保留肝动脉血供的肝血流阻断法能有效控制肝断面出血，明显保护了肝脏功能，且并未延长手术时间。
ObjectiveTo explore the risk factors of intraabdominal complications (IACs), pancreatic fistula (PF), and operative death after pancreatoduodenectomy (PD), and to provide a theoretical basis in reducing the rates of them. MethodsClinical data of 78 patients who underwent standard PD surgery in The Third People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from Jun. 2003 to Nov. 2011 were collected to analyze the influence factors of IACs, PF, and operative death. ResultsThere were 29 cases suffered IACs (13 cases of PF included), and 6 case died during 1 month after operation. Univariate analysis results showed that IACs and PF occurred more often in patients with soft friable pancreas, diameter of main pancreatic duct less than 3 mm, preoperative biliary drainage, no pancreatic duct stenting, and without employment of somatostatin (P < 0.05), no influence factor was found to be related to operative death. Multivariate analysis results showed that patients with no pancreatic duct stenting (OR=1.867, P=0.000), soft texture of remnant stump (OR=1.356, P=0.046), and diameter of main pancreatic duct less than 3 mm (OR=2.874, P=0.015) suffered more IACs; PF was more frequent in patient with no pancreatic duct stenting (OR=1.672, P=0.030), soft texture of remnant stump (OR=1.946, P=0.042), and diameter of main pancreatic duct less than 3 mm (OR=1.782, P=0.002);no independent factor was found to have relationship with operative death. ConclusionsSoft texture of remnant stump, diameter of main pancreatic duct less than 3 mm, and no pancreatic duct stenting are independent risk factors that should be considered in indications for PD surgery.
