This prospective study found that 6.2% of women developed new pelvic pain and 16.4% had persistent pelvic pain one year after hysterectomy, identifying preoperative factors associated with these outcomes.

This prospective longitudinal multicenter study in Sweden followed 440 women undergoing benign hysterectomy to determine the prevalence of de novo and persistent pelvic pain one year after surgery, and to assess risk factors. Pain intensity and spatial bodily pain distribution were measured preoperatively, shortly after surgery, and again at one year using a questionnaire plus Margolis pain drawings, and pain sensitivity was evaluated with quantitative sensory testing, with quality of life (EQ-5D-3L, SF-36) and psychological distress (HADS) assessed preoperatively. After hysterectomy, 6.2% developed de novo pelvic pain and 16.4% had persistent pelvic pain, with de novo pelvic pain occurring only in women who had non-pelvic pain only preoperatively; risk factors for de novo pain included longer hospital stay, higher preoperative pain intensity and number of pain areas, anxiety, and low EQ-5D-3L health index. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index, so its relevance to endometriosis/adenomyosis is not directly established in the provided text.

Abstract

BACKGROUND: The objectives were to determine the prevalence of de novo and persistent pelvic pain after benign hysterectomy and to assess risk factors. METHODS: A Swedish prospective multicenter study of 440 women undergoing benign hysterectomy was conducted between October 2011 and March 2017. Measures of pain, the spatial extent of bodily pain, and pain sensitivity were assessed using a self-reporting questionnaire, Margolis's patient pain drawing, and quantitative sensory testing of pain thresholds for pressure, heat, and cold, respectively. Quality of life was evaluated by EQ-5D-3L and SF-36. Psychological distress was assessed by the Hospital Anxiety and Depression Scaleand the Stress-Coping Inventory. Logistic regression models were used to assess risk factors, and the outcome was presented as an adjusted odds ratio (aOR) and 95% confidence interval (CI). RESULTS: Preoperatively, 18.0% of the women reported no bodily pain, 41.5% had pelvic pain, either as the only location (7.0%) or along with pain in other locations (34.5%), and 40.5% had non-pelvic pain only. Postoperatively, 6.2% developed de novo pelvic pain and 16.4% had persistent pelvic pain. De novo pelvic pain developed exclusively in women who preoperatively had non-pelvic pain only. Risk factors for de novo pelvic pain were a long hospital stay (aOR 1.50 (95%CI) 1.02-2.21)), high preoperative pain intensity (aOR 1.25 (95%CI 1.01-1.62)) and a high number of pain areas (aOR 1.15 (95%CI 1.05-1.27)), along with anxiety (aOR 10.61 (95%CI 1.84-61.03)) and low EQ-5D-3L health index (aOR 0.02 (95%CI 0.00-0.31)). Risk factors for persistent pelvic pain were lower age (aOR 0.89 (95%CI 0.81-0.97)), higher number of pain areas (aOR 1.08 (95%CI 1.02-1.14)), and a higher frequency of preoperative pain (aOR 12.75 (95%CI 2.24-72.66)). CONCLUSION: Although hysterectomy appeared to be reasonably effective in curing pelvic pain, a non-negligible proportion of women developed de novo pelvic pain or had persistent pelvic pain. De novo pelvic pain seemed to affect only those who preoperatively had widespread bodily pain. Women at risk for de novo and persistent pelvic pain after hysterectomy could be identified preoperatively. TRIAL REGISTRATIONS: The study was retrospectively registered in ClinicalTrial.gov (NCT01526668) on 01/27//2012.
