摘要
目的:探讨行直肠癌前切除术(Dixon)直肠癌患者的术前术后直肠和肛管功能变化。方法:采用4通道水灌注式肛门直肠压力检测系统,对46例直肠癌患者进行Dixon术前术后直肠肛门压力测定。结果:Dixon术后粪便质地与术前比较,差异无统计学意义,排便次数较术前有所增加,里急后重感明显增加,控制排便的能力较术前有所减弱。肛管静息压、肛管最大收缩压、肛管最大收缩时间均较术前明显降低(均P<0.05)。肛管直肠抑制反射均为阳性,但压力下降值及下降的百分比均较术前有所下降(均P<0.05)。结论:直肠癌患者Dixon术后肛管自制功能和肛管括约功能均有所下降。
Objective To explore the metergasis of patients with rectal cancer before and after Dixon. Methods The pressure of anorectnm about patients（ n =46） with rectal cancer was determined before and after Dixon,using anorectal manometry detection system with four-passage water infusing. Results There was no significant difference in faeces texture after with before Dixon （ P 〉0.05 ）. Defecation frequency and rectal tenesmus feeling were obviously increased, but continence function was weakened. The anal sphincter resting pressure, maximal squeeze pressure and maximal squeeze time were decreased compared to those of before Dixon （ P 〈 0.05 ）. All of the rectal anal inhibitory reflex were positive ,but the value and percentage of drawdown pressure was decreased by compared before Dixon（P 〈 0.05 ）. Conclusion The anal canal function of self-control and sphincter decreased in patients with rectal cancer after Dixon.
