钩突完全切除对胰十二指肠切除术后胰瘘发生率的影响

目的 分析胰十二指肠切除术后胰瘘发生的可能因素,探讨钩突完全切除对降低胰瘘发生率的影响.方法 回顾性分析2004年1月至2009年6月单一手术小组收治并行胰十二指肠切除的68例壶腹周围疾病患者的临床资料.以术后腹腔引流液淀粉酶水平诊断胰瘘并行临床资料分析,对可能造成腹腔引流液淀粉酶异常升高的相关因素:钩突是否完全切除、胰肠吻合方式、胰腺纤维化等进行统计学分析.结果 本组胰瘘发生率为33.8%;单因素分析显示:钩突是否完全切除(P=0.000)及血糖水平(P=0.045)与胰瘘关系密切;多因素分析显示本组病例胰瘘发生的独立危险因素为钩突是否完伞切除(P=0.000,OR=7.771),而胰腺纤维化、吻合方式、疾病类型等均不构成胰瘘发生的独立危险因素.结论 完全切除胰腺钩突能够防止"残留钩突型胰瘘"的发生,进而降低胰十二指肠切除术后胰瘘发生率.

Total resection of pancreatic uncinate process reduces the incidence of pancreatic fistula following pancreaticoduodenectomy

Objective To study the causes of pancreatic fistula following pancreatioduodenectomy, and evaluate the effect of total pancreatic uncinate process resection on the prevention of pancreatic fistula by analyzing the potential aetiology of pancreatic fistula after pancreaticoduodenectomy.Methods The clinical data of 68 patients, who were admitted into the No. 1 ward of Surgical Department of Peking University First Hospital during the period from Jan. 2004 to Jun. 2009, were retrospectively analyzed. The day-average level of amylase higher than 3 times of normal value, as measured from the drainage of peritoneal cavity, serves as the diagnostic criterion of the postoperative pancreatic fistula.Factors relevant to fistula, which result in the abnormal increase of the amylase in the drain, such as the extent of resection of pancreatic uncinate process, the anastomotic manners of pancreas and digestive tract, and the pancreatic fibrosis were statistically analyzed. Results The incidence of pancreatic fistula was 33. 8% according to the diagnostic criterion mentioned above; Single factor analysis showed that the resection extent of uncinate process (P = 0. 000) and the level of serum glucose ( P = 0. 045 ) were correlated with the occurrence of pancreatic fistula. Multivariate analysis identified that the independent risk factor for pancreatic fistula was the resection extent of uncinate process(P =0. 000). Pancreatic fibrosis, the manners of the anastomosis of pancreas and digestive tract were not independent risk factors. Conclusion Total resection of uncinate process could prevent pancreatic fistula from residual pancreatic uncinate process, hence reduce the incidence of pancreatic fistula following pancreaticoduedenectomy.
