Background: Endometriosis is a chronic gynecological disease that is characterized by the presence of endometrial tissue outside the uterine cavity. The main symptoms include dysmenorrhea, dyspareunia, chronic pelvic pain, and infertility. These symptoms impair the lives of most of the women suffering from the disease. Surgical resection of endometriotic lesions is an effective means of treating dysmenorrhea, but the risk of recurrence is high. Western medicine has limited use for treating it due to side effects and ineffectiveness. The purpose of this study is to verify the effectiveness and safety of acupuncture.
Methods/design: This trial will be carried out in four parts. A total of 106 eligible patients with pelvic pain related to endometriosis will be randomly assigned into two groups, in a 1:1 ratio, as the treatment group or the control group. The participants assigned to the treatment group will be treated with acupuncture treatment at Guanyuan (CV4), Sanyinjiao (SP6), Taichong (LR3), Zhaohai (KI6) and Qichong (ST30) while the control group will receive acupuncture at non-acupoints. The trial will include three menstrual cycles of treatment and three menstrual cycles of follow-up. The primary outcome is pelvic pain that will be assessed by means of a 10-cm visual analog scale (VAS). At each stage, we will evaluate the safety of the acupuncture treatment.
Discussion: The study will compare the effectiveness and safety of acupuncture with comfort needles on pelvic pain related to endometriosis in the hope of providing significant evidence for using acupuncture on pelvic pain related to endometriosis.
