ORLANDO -- Women with chronic pelvic pain responded as well to medical treatment as they did to surgery, according to a prospective, observational cohort study of 370 patients that was carried out 1 year after treatment, Dr. Georgine Lamvu said at the annual meeting of the South Atlantic Association of Obstetricians and Gynecologists.
About 15% of women report having chronic pelvic pain (CPP) in their lifetime. It is the primary indication for 12% of hysterectomies and 40% of laparoscopies and costs over $2 billion annually, said Dr. Lamvu of the University of North Carolina at Chapel Hill.
The mean pain level score, as assessed by the McGill Pain Questionnaire, was 30, or moderate to severe, in 49% of both medically and surgically treated women who were referred to the university's pelvic pain clinic for evaluation of continued CPP.
Likewise, moderate to severe depression, as measured by the Beck Depression Inventory scale, was diagnosed in 22% of both groups.
Surgical treatment ranged from diagnostic laparoscopy to hysterectomy, and medical treatment consisted of pharmacotherapy, psychotherapy, and physical therapy.
One year later, the mean McGill Pain Questionnaire score had decreased from 30 to 23 in both groups. Overall, depression scores were unchanged in 48%, improved in 32%, and worsened in 20%. However, depression did not predict worse outcome, Dr. Lamvu said. "We were surprised, but that is what we found. Outcomes were similar with both treatment types."
Dr. Lamvu said she is planning further studies that will focus on physician-patient relationships, which may influence outcomes for pain treatment in women with CPP. "There may actually be some biological reasons for the way women respond to pain ...
