Effect of biofeedback therapy combined with Shugang Decoction hip bath on functional anorectal pain

Objective To study the effect of biofeedback therapy combined with Shugang Decoction hip bath in the treatment of functional anorectal pain, and further to explore an effective therapy for such diseases. Methods A total of 100 patients with functional anorectal pain in the Outpatient Department of Jinhua Central Hospital from September 2018 to August 2019 were collected and randomly divided into observation group and control group, with 50 cases each group. The control group received the biofeedback therapy, while the observation group received additional Shugang Decoction on the basis of biofeedback therapy. Pain visual analogue scale(VAS), anorectal manometry, pelvic floor function test, symptom score and clinical efficacy were compared between the two groups. Results After the treatment, the VAS score in the observation group was(1.6±1.0), which was lower than that(2.5±1.3) in the control group, t=3.880, P<0.001; the rectal resting pressure, anal resting pressure and maximum contraction pressure in the observation group were lower than those in the control group, all P<0.05; the relaxation state AVG, rapid contraction AVG Peak, intermittent contraction AVG, and coefficient of variation(CV) in the observation group were better than those in the control group, all P<0.05; the symptom score of the observation group was(14.6±7.0), which was lower than that(18.2±7.6) of the control group, t=2.464, P=0.016; the total effective rate of the observation group(92.0%) was higher than that of the control group(74.0%), χ²=5.741, P=0.017. Conclusion Biofeedback therapy combined with Shugang Decoction hip bath has a significant effect on functional anorectal pain. It can obviously relieve pain of patients, reduce anal and rectal pressure, improve pelvic floor function and reduce symptom scores. It is worthy of clinical implementation.
