Objective To study the independent risk factors and treatment situation for intestinal obstruction after abdominal surgery to provide the basis for clinical diagnosis and treatment .Methods 209 cases of abdominal surgery in our hospital from January 2012 to December 2013 were selected and treated by operation .The patients′general information(gender ,age ,disease type) ,anesthesia type ,operation time ,intraoperative operating ,postoperative body temperature operation ,WBC count and blood pressure were performed the statistical analysis .Results Among 209 cases ,40 cases(19 .14% ) of postoperative ileus occurred .Among them ,2 cases(0 .96% )of paralytic ileus were cured after medication therapy ;in 5 cases(2 .39% ) of mechanical ileus ,4 cases were cured with conservative treat-ment and 1 case was cured after surgery ;in 33 cases(15 .19% ) of inflammatory intestinal obstruction ,29 cases were cured by conservative treatment ,4 cases were performed enterolysis after abdominal exploration .The occurrence rate of postoperative intestinal obstruction in the elderly ,non-tumor ,anesthesia with opiod drugs ,long operation time ,hy-poproteinemia ,extensive intestinal adhesion ,higher postoperative body temperature and low WBC count was higher , the differences had statistical significance (P<0 .05) .The Logistic regression analysis showed that the independent risk factors for the occurrence of intestinal obstruction after abdominal surgery were anesthesia with opiod drugs ,op-eration durations ,preoperative complications ,and WBC count ( P< 0 .05 ) .Conclusion Among 209 cases ,40 cases (19 .14% ) of postoperative ileus occurred .Among them ,2 cases(0 .96% )of paralytic ileus were cured after medica-tion therapy ;in 5 cases(2 .39% )of mechanical ileus ,4 cases were cured with conservative treatment and 1 case was cured after surgery ;in 33 cases(15 .19% )of inflammatory intestinal obstruction ,29 cases were cured by conservative treatment ,4 cases were performed enterolysis after abdominal exploration .The occurrence rate of postoperative intes-tinal obstruction in the elderly ,non-tumor ,anesthesia with opiod drugs ,long operation time ,hypoproteinemia ,exten-sive intestinal adhesion ,higher postoperative body temperature and low WBC count was higher ,the differences had statistical significance(P<0 .05) .The Logistic regression analysis showed that the independent risk factors for the occurrence of intestinal obstruction after abdominal surgery were anesthesia with opiod drugs ,operation durations , preoperative complications ,and WBC count(P<0 .05) .%目的：对腹部术后发生肠梗阻的独立危险因素和治疗情况进行研究，为临床诊治提供依据。方法选择2012年1月至2013年12月在该院进行腹部手术的患者209例，所有患者均给予手术治疗，统计分析患者的一般资料（性别、年龄、疾病类型）、麻醉类型、手术时间、术中操作、术后体温、白细胞（WBC ）计数、血压。结果209例患者术后发生肠梗阻40例（19．14％）。其中麻痹性肠梗阻2例（0．96％），给予药物治疗后痊愈；机械性肠梗阻5例（2．39％），经保守治疗后痊愈4例，1例经手术治疗后痊愈；炎性肠梗阻33例（15．19％），经保守治疗后痊愈29例，4例行腹部探查后给予肠粘连松解术治愈。年龄越大、非肿瘤患者、使用阿片类药物麻醉、手术时间越长、低蛋白血症、肠粘连范围越广、术后体温越高、WBC计数越低肠梗阻发生率就越高，差异均有统计学意义（ P＜0．05）。经Logistic回归分析，是否阿片类药物麻醉、手术时间、低蛋白血症、WBC计数为腹部术后发生肠梗阻的独立危险因素（P＜0．05）。结论在腹部手术时尽量避免选择阿片类药物麻醉、缩短手术时间、降低低蛋白血症发生率、保持WBC计数正常，并且及时采取针对性措施对肠梗阻进行治疗，可降低肠梗阻发生率。
