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.
