摘　　要：目的:探讨生物反馈训练辅助治疗梗阻性便秘患者对粪便性状、排便时间与排便频度的影响。方法:选取我院收治的90例梗阻性便秘患者,根据随机数字表法分为3组,A组接受常规治疗,B组于常规治疗基础上进行固定式生物反馈训练(FBF),C组于常规治疗基础上进行自适应式生物反馈训练(ABF),比较3组治疗前后肛直肠功能、粪便性状、排便时间、排便频度和临床疗效。结果:治疗后,直肠肛门压力梯度:A组B组>C组(P<0.05),B组与C组肛管静息压、直肠肛门抑制反射阈值显著小于A组(P<0.05),且肛管松弛率显著大于A组(P<0.05);C组粪便性状4~7型占比明显高于其余两组(P<0.05),且B组4~7型占比明显高于A组(P<0.05);排便时间:A组>B组>C组(P<0.05),排便频度:A组<B组<C组(P<0.05);C组总有效率显著高于A组与B组(P<0.05),结论:生物反馈训练尤其是ABF可有效改善梗阻性便秘患者肛直肠功能,在改善粪便性状、缩短排便时间、增加排便频度上具有明显优势,可获得更好的临床疗效。Objective: To investigate the effect of biofeedback training-assisted treatment on the character of fecal, defecation time and defecation frequency of patients with obstructive constipation. Methods: Ninety patients with obstructive constipation treated in the hospital were selected and divided into three groups by the random number table method. Group A was given conventional treatment,group B was given fixed biofeedback training(FBF) based on conventional treatment, and group C was given adaptive biofeedback training(ABF) based on conventional treatment. The anorectal function, fecal characters, defecation time and defecation frequencies before and after treatment and clinical effects were compared among the three groups. Results: After treatment, the order of anorectal pressure from low to high was as follows: group A, group B, group C(P<0.05). The order of paradoxical contraction rate from high to low was as follows: group A, group B, group C(P<0.05). The anal canal rest pressure and anorectal suppression reflex thresholds of group B and group C were significantly smaller than those of group A(P<0.05), and the anal canal relaxation rate was significantly larger than that in group A(P<0.05). The proportion of type 4~7 fecal character was the highest in group C, followed by group B, and was the lowest in group A(P<0.05). The defecation time of group A was the longest, followed by group B, group C(P<0.05), and the defecation frequency of group A was the least, followed by group B, group C(P<0.05). The total effective rate of group C was significantly higher than that of group A or group B(P<0.05). Conclusion: Biofeedback training, especially ABF, can effectively improve the anorectal function of patients with obstructive constipation. It has obvious advantages in improving fecal character, shortening defecation time and increasing defecation frequency.
