Efficacy of self-made Runchangling combined with biofeedback in the treatment of functional outlet obstruction constipation
Objective To explore the efficacy of self-made Runchangling combined with biofeedback in the treatment of functional outlet obstruction constipation(FOOC).Methods A total of 83 FOOC patients who were admitted to Changzhou Hospital of Traditional Chinese Medicine from February 2020 to February 2022 were selected in this study.They were randomly divided into control group(n=41)and observation group(n=42)according to random number table method.The patients were treated with biofeedback for 4 weeks in both groups,and self-made Runchangling was additionally given to the patients in the observation group.The curative effect,TCM symptom scores,anal dynamics indicators,defecation time,defecation interval,72-hour defecation frequency,and the recurrence of FOOC within 3 months after treatment were compared between the two groups.Results The response rate of the observation group was higher than that of the control group(92.86%[39/42],73.17%[30/41],P<0.05).The toaditional chinese medicine(TCM)main symptom score,secondary symptom score and total TCM symptom score were decreased after treatment in both groups,and these scores in the observation group were lower than those in the control group(all P<0.05).The anal maximal contraction pressure(AMCP)and anal rest pressure(ARP)were decreased after treatment in both groups,and the duration of anal canal extrusion was shortened.The above-mentioned three parameters in the observation group were lower than those in the control group(all P<0.05).The defecation time and defecation interval in the observation group were less than those in the control group,and the number of defecation within 72 hours in the observation group was more than that in the control group(all P<0.05).The recurrence rate of the observation group was lower than that of the control group within 3 months after treatment(9.52%[4/42],26.83%[11/41],χ2=4.196,P=0.041).Conclusion Self-made Runchangling combined with biofeedback therapy can improve TCM symptoms and anal dynamics indicators,shorten defecation interval and defecation time,increase defecation frequency,and reduce the recurrence in FOOC patients.
