Background and aims: Individuals with non-acute pain are challenged with variable pain responses following surgery as well as psychological challenges, particularly depression and catastrophizing. The purpose of this study was to compare pre- and postoperative psychosocial tests and the associated presence of sensitization on a cohort of women undergoing elective laparoscopic surgery for non-acute pain defined as pain sufficient for surgical investigation without persistent of chronic pain.
Methods: The study was a secondary analysis of a previous report (Am J Obstet Gynecol 2014 Oct;211(4):360-8.). The study was a prospective cohort trial of 77 women; 61 with non-acute pain and 16 women for a tubal ligation. The women had the following tests: Pain Disability Index, Pain Catastrophizing Scale, CES-D (Center for Epidemiologic Studies Depression Scale) depression scale and the McGill Pain Scale (short form) as well as their average pain score and the presence of pain sensitization. All test scores were correlated together and comparisons were done using paired t-test.
Results: There were reductions in pain and psychosocial test scores that were significantly correlated. Pre-operative sensitization indicated greater changes in psychosocial tests.
Conclusions: There was a close association of tests of psychosocial status with average pain among women having surgery on visceral tissues. Incorporation of these tests in the pre- and postoperative evaluation of women having laparoscopic surgery appears to provide a means to a broader understanding of the woman's pain experience.
