ObjectiveTo evaluate the outcome of surgical or hormone-based pharmacological treatment for deep infiltrating endometriosis (DIE) in patients with pain symptoms.Study DesignA retrospective cohort study of 122 women with DIE of the bowel was conducted: 61 women underwent surgical treatment due to poor pain control and 61 received hormone-based treatment alone for at least six months. Chronic pelvic pain, dysmenorrhea, deep dyspareunia, dyschezia and dysuria were evaluated by a visual analog scale (VAS) to measure pain on a scale from 0 to 10. Dyspareunia was further evaluated using the Deep Dyspareunia Scale (scores of 0-3).ResultsSurgery (n = 61 women) was performed at a mean of 3.3 ± 1.6 years previously, while hormone-based treatment alone (n = 61 women) was used for a mean of 3.0 ± 1.41 years. After surgery, women without a desire to procreate received hormone-based treatment. Before treatment, the most intense endometriosis-related pain in the surgical treatment group and hormone-based treatment group alone were chronic pelvic pain (VAS = 9.48 ± 1.49; 8.57 ± 2.22), dysmenorrhea (VAS = 9.61 ± 1.45; 9.02 ± 1.35) and deep dyspareunia (VAS = 8.04 ± 2.82; 7.47 ± 3.21, respectively), all with mean pain scores of around 8 (0-10) in both groups. Both treatments were effective at reducing all symptoms (p < .001). The surgical treatment proved to be more effective and more enduring at improving chronic pelvic pain (p < .001), dyschezia (p = .003) and deep dyspareunia (p < .001). Regarding deep dyspareunia, using the deep dyspareunia scale, ∼70% of surgically treated women scored 0 or 1 (absent or mild deep dyspareunia) after treatment, compared to scores 2 or 3 (intense dyspareunia) in about 70% of the group using hormone-based treatment (p < .001).ConclusionBoth types of treatment, surgical and pharmacological, effectively improved pain symptoms associated with DIE. However, improvement in chronic pelvic pain, dyschezia and deep dyspareunia was greater and longer-lasting after surgery.
