Wipple术后胃瘫危险因素的Logistic回归分析

目的探讨Whipple术后胃瘫发生的危险因素。方法2002年1月至2006年4月共对166例患者行Whipple手术,对其临床资料进行分析。以手术后是否发生胃瘫为因变量,进行单因素及多因素非条件Logistic逐步回归分析。结果60例患者术后发生胃瘫,单因素分析显示15个因素中有6个与术后胃瘫发生有关。非条件Logistic逐步回归分析模型共筛出7个术后胃瘫的相关因素。结论术前出现消化道梗阻症状、广泛性淋巴清扫术、术后腹腔感染、术后开始行肠内营养时间、术后血糖水平为术后胃瘫的危险因素;而术前行经皮肝穿刺置管引流（percutaneous transhepatic eholangial drainage,PTCD）及术后总蛋白（terminal protein,TP）水平是术后胃瘫的保护性因素。

Risk factors for postoperative gastroparesis syndrome after pancreaticoduodenectomy with binary logistic regression

Objective To study the risk factors of postoperative gastroparesis syndrome after pancreaticoduodenectomy.Method Clinical data of 166 patients who underwent pancreaticoduodenectomy from January 2002 to April 2006 were analyzed with binary logistic regression in order to explore the risk factors of postoperative gastroparesis syndrome after pancreaticoduodenectomy.Results There were 60 patients occurred postoperative gastroparesis syndrome after pancreaticoduo-decectomy.Among 15 factors,6 factors were proved to be the risk factors of postoperative gastroparesis syndrome after pancreaticoduodenectomy by unitary anylasis;7 factors were proved related factors of postoperative gastroparesis syndrome after pancreaticoduodenectomy by analyzed with binary logistic regression. Conclusions The risk factors are preoperative gastro-intestinal obstruction syndrome,extensive lymphadenectomy,postoperative abdominal cavity infection,starting time of postoperative enteral nutrition, postoperative blood glucose level;The protective factors are preoperative percutaneous transhepatic cholangial drainage(PTCD)and postoperative blood terminal protein(TP)level.
