摘　　要： 目的探究肛门测压仪在评估直肠癌保肛手术患者术前后肛门功能中应用。方法选取我院胃肠外科收治的63例行保肛术式的直肠癌患者进行肛肠测压,设为观察组,并选取35例同时期入院体检正常人为对照组,检测术前对照组和观察组及术后1、6、12个月肛门动力学指标。结果正常对照组与观察组术前在肛门静息压(ARP)、肛管最大收缩压(MSP)、直肠静息压(RRP)、直肠初始感觉容量(RVST)、直肠便意感觉容量(UV)、直肠最大耐受容量(MTV)、直肠顺应性(RC)、肛管高压带(HPZ)和直肠肛门抑制反射(RAIR)比较差异无统计学意义(P>0.05)。术后1、6个月肛门排便功能优良率(22.22%和31.75%)明显低于术前(90.48%),差异有统计学意义(χ~2=59.660和45.718,P<0.05),术后12个月与术前比较差异无统计学意义(χ~2=3.037,P>0.05)。术后1、6、12个月患者MTV和RAIR指标明显低于术前,差异具有统计学意义(P<0.05)。患者术后各时期MSP指标与术前比较差异无统计学意义(P>0.05)。结论直肠癌低位前切除术后在短期内能够影响患者肛门功能,肛肠动力学指标客观评价直肠癌低位前切除术术后肛门功能恢复程度。 Objective To explore the application of anal pressure measurement device in evaluating the anal function in patients with rectal cancer before and after anal sphincterpreservation surgery. Methods Anal pressure measurement was performed in 63 patients with rectal cancer who underwent anal sphincterpreservation surgery in the department of anorectal surgery, and 35 normal people were selected as the control group at the same time. The anal dynamic indexes in the control group before surgery and those in patients with rectal cancer at 1 month, 6 months and 12 months after surgery were detected. Results There were no significant differences in ARP, MSP, RRP, UV, RVST, MTV, RC, HPZ and RAIR between the normal control group and patients with rectal cancer before surgery （P〉0.05）. One month and 6 months after surgery, the excellent and good rate of defecation function （22.22%, 31.75%） were significantly lower than that before operation （9048%） （χ^2=59.660, 45.718, P〈0.05）. 12 months after surgery, there were no significant differences （χ^2=3.037, P〉 0.05）. One month, 6 months and 12 months after surgery, MTV and RAIR were significantly lower than those before surgery （P〈0.05） while MSP showed no significant difference （P〉0.05）. Conclusion：Low resection for rectal cancer has effect on anal function in patients in short term, and the anorectal dynamic indexes can be used to evaluate the recovery of anal function after surgery.
