尿流改道早期术后小肠梗阻的多因素分析

目的 探讨影响全膀胱切除尿流改道早期术后小肠梗阻（EPSBO）发生率的潜在因素.方法 1996年1月～2005年1月,因膀胱癌行根治性全膀胱切除尿流改道术171例,多因素统计学方法分析影响EPSBO发生率的因素.结果 多因素logistic回归分析：术中未输血的OR值为6.470,95%CI：1.394～30.021,有统计学意义（P＜0.05）;其余因素如：性别、年龄、术式、手术时间、腹腔内应用防粘连剂等无统计学意义（P＞0.05）.结论 统计学显示,术中未输血是根治性全膀胱切除尿流改道EPSBO发生率升高的独立危险因素.性别、年龄、术式、手术时间等不是影响EPSBO的独立危险因素.腹腔内应用防粘连剂未显示出对EPSBO的保护作用.

Multivariate analysis of early postoperative small bowel obstruction after radical cystectomy and urinary diversion

Objective] To study the potential factors that affect the rate of early postoperative small bowel obstruction (EPSBO) after radical cystectomy and urinary diversion. Methods] From 1996.1 to 2005.1, 171 patients accepted radical cystectomy and urinary diversion for bladder cancer. Perioperative variables were analyzed by multivariate analysis. Results] Multivariate logistic regression analysis indicates non-blood transfusion in operation was an independent risk factor, and it was correlated with a higher EPSBO rate (odds ratio 6.470, 95%CI: 1.394~30.021, P <0.05),other factors, such as age, sex, surgery type, length of operation, using intra-abdominal adhesion prevention barriers, etc, were not statistically significant factors to EPSBO in this study (P >0.05). Conclusions] The statistical results of this study indicate: non-blood transfusion in operation is an independent risk factor to EPSBO after radical cystectomy and urinary diversion. age, sex, surgery type, length of operation, etc, are not risk factors to EPSBO. Using intra-abdominal adhesion prevention barriers is not a preventive factor to EPSBO in this study.
