Fluoroestradiol PET-MRI imaging for detection of endometriosis lesions and symptom correlation.

Endometriosis is a common cause of infertility, pelvic pain, and dysmenorrhea and there are prior case reports of lesion detection using an 18F-fluoroestradiol (FES) tracer with positron emission tomography (PET). We aimed to further investigate the use of the FES tracer in the context of PET-magnetic resonance (PET-MR) imaging. We administered FES to 6 patients and then imaged them using a Siemens mMR PET-MR scanner. Each patient was taken to surgery within 30 days after imaging, and surgical visualization served as the gold-standard for diagnosis. PET did not prove to be as sensitive as MR (50% per-patient sensitivity versus 67% per-patient and 35% versus 48% per-lesion), and did not show any additional sites over and above MR. When MR was used to localize lesions on PET after imaging, there was insufficient evidence of an association between total tracer uptake and reported pain intensity (P=0.25). FES PET-MR offers no additional value to MR for endometriosis.

Updates on the Surgical Approach to Fibroids: The Importance of Radiofrequency Ablation.

Uterine fibroids are the most common benign neoplasm of the female pelvis and have a lifetime prevalence exceeding 80% among African American women and approaching 70% among Caucasian women. Approximately 50% of women with fibroids experience symptoms which can range from heavy menstrual bleeding and bulk-related symptoms such as pelvic pressure with bladder and bowel dysfunction to reproductive dysfunction (e.g., infertility or obstetric complications) and pain. The choice of treatment is primarily guided by the type of symptoms in the individual patient and whether they prefer to retain fertility. While hysterectomy provides definitive resolution of fibroid symptoms and remains the most common treatment option, this procedure is invasive with a long recovery window. Radiofrequency ablation (RFA) is now emerging as a uterine preserving and minimally invasive therapy for symptomatic fibroids. Since its introduction, growing evidence for safety and efficacy of RFA has been generated with low rates of complications. This review will discuss RFA for the management of symptomatic uterine fibroids with a special focus on technical approaches, short- and long-term outcomes including fertility outcomes.

Myofascial Pain in Hysterectomy Patients.

STUDY OBJECTIVE: To assess the prevalence of myofascial pain in women undergoing uncomplicated, minimally invasive hysterectomy for chronic pelvic pain, to identify clinical and demographic factors associated with preoperative myofascial pain, and examine the association between myofascial pain and postoperative pain in hysterectomy patients. DESIGN: A retrospective cohort study. SETTING: A tertiary care teaching hospital. PATIENTS: A total of 353 adult women who underwent uncomplicated, minimally invasive hysterectomy between January 2014 and 2016. INTERVENTIONS: All women underwent a preoperative pelvic floor examination. Myofascial pain was diagnosed as tenderness and reproduction of pain symptoms in at least 2 of 6 pelvic floor muscles. Demographics, comorbidities, and intraoperative characteristics were compared between women with and without preoperative myofascial pain. MEASUREMENTS AND MAIN RESULTS: Of the 353 women who underwent hysterectomy, the prevalence of myofascial pain was 42.7% (86.0% in patients with chronic pelvic pain [CPP] compared with 13.7% without CPP). Women with myofascial pain were more likely younger, Caucasian, sexually active, and with comorbid pain conditions. Patients with myofascial pain used a greater number of adjuvant pain medications before surgery including opiates (29.5%) but were only half as likely to use muscle relaxants (12.1%) for preoperative pain control. Contrastingly, in women without myofascial pain before surgery, controlled substances such as opiates (8%, p <.01) and benzodiazepines (3%, p <.01) were used at a three- fold lower frequency. Postoperative pain score was higher in patients with myofascial pain, with 37% reporting a visual analog scale score greater than 5 at the routine postoperative visit compared with only 1% of patients without myofascial pain. CONCLUSION: Myofascial pelvic pain must be considered in the evaluation of CPP, especially in surgical candidates. Women with myofascial pelvic use a greater amount of pain medication preoperatively and have higher pain scores postoperatively. Identification of these high-risk patients before surgery may improve pre and postoperative pain management with a multimodal therapy approach.
