Objective To study the effect of behavior-changes-in-stages theory on defecation function of lower rectal cancer after sphincter-preserving operation. Methods 84 patients with lower rectal cancer undergoing sphincter-preserving operation from June 2013 to June 2016 were divided into control group (n=42)and intervention group (n=42)according to their willingness to care.The control group implemented routine nursing,mainly for diet intervention,wound care,bowel function training and in the intervention group the behavior-changes-in-stages theory was used.Comparisons were done between the groups in terms of the anus incontinence defecation function and quality of life for 6 months after operation. Result The degrees of anus incontinence and defecation function in the intervention group were both significantly better than those in the control group 6 months after the operation (P<0.05). Conclusions The behavior-change-in-stages plays a significant role in the postoperative rehabilitation.It can significantly reduce the anus incontinence, better the bowel function,improve the quality of life and promote rehabilitation.%目的 探讨基于行为分阶段改变理论为指导的护理干预对低位直肠癌保肛术后患者排便功能及生活质量的影响.方法 选择2013年6月至2016年6月在本院住院的84例低位直肠癌保肛术后患者,根据入院时间分为对照组和干预组,每组各42例.对照组院内进行伤口护理、饮食、生活指导及肛门功能锻炼指导;院外实施电话随访和家访,共6个月.干预组院内和院外实施基于行为分阶段改变理论为指导的护理干预,院外共干预6个月.比较两组患者术后6个月后肛门失禁程度、排便功能和生活质量的差异.结果 干预组术后大便失禁程度轻于对照组;排便功能和生活质量优于对照组(P<0.05,P<0.001).结论 基于行为分阶段改变理论为指导的护理干预可减轻低位直肠癌保肛术后患者大便失禁程度,改善排便功能,进而提高其生活质量.
