Clinical Observation of Compound Angelica Injection Combined With Biofeedback in The Treatment of Functional Anorectal Pain
复方当归注射液联合生物反馈治疗功能性肛门直肠痛的临床疗效观察

摘要

目的 研究复方当归注射液联合生物反馈治疗功能性肛门直肠痛的临床疗效。方法 选取2020年6月—2020年11月于湖北省中医院肛肠科门诊治疗的符合纳入标准的功能性肛门直肠痛患者60例作为研究对象，采用随机数表法分为治疗组与对照组，各30例，对照组采用单纯的生物反馈疗法，治疗组在生物反馈疗法的基础上联合复方当归注射长强穴及肛周局部注射治疗，对比2组患者的疼痛视觉模拟评分（VAS）和临床疗效。结果 治疗组治疗后的VAS评分为（2.45±1.88）分，低于对照组的（4.07±2.02）分（t = 3.204，P＜0.05）；治疗组的总有效率（93.33%）高于对照组（70.00%），χ2=4.01，P＜0.05。结论 复方当归注射液联合生物反馈能有效缓解患者疼痛，在治疗功能性肛门直肠痛上明显优于单纯生物反馈疗法，操作简便，价格低廉，微创且又避免了长期使用镇痛药物的毒副作用，有较好的临床实用性。

Abstract

Objective To study the clinical efficacy of compound Angelica injection combined with biofeedback in the treatment of functional anorectal pain.
Methods：A total of 60 patients with functional anorectal pain who were treated in the outpatient department of Proctology, Hubei Hospital of Traditional Chinese Medicine from June 2020 to November 2020 and met the inclusion criteria were selected as the research objects. They were divided into treatment group and control group by random number table method, with 30 patients in each group. The control group received simple biofeedback therapy. On the basis of biofeedback therapy, the treatment group was combined with compound Angelica injection at Changqiang acupoint and local injection around anus. Visual analogue scale (VAS) of pain and clinical efficacy in twogroups were compared.
Results: The VAS score of the treatment group was (2.45±1.88), lower than that of the control group (4.07±2.02)(t = 3.204, P < 0.05). The total effective rate in treatment group (93.33%) was higher than that in control group (70.00%), χ2=4.01, P < 0.05.
Conclusion  : Compound Angelica injection combined with biofeedback can effectively relieve the pain of the patients, and is obviously superior to simple biofeedback therapy in the treatment of functional anorectal pain. It is simple, inexpensive, minimally invasive, and avoids the toxic and side effects of long-term use of analgesics, so it has good clinical practicability.
