Assessment of levator hiatal area using 3D/4D transperineal ultrasound in women with deep infiltrating endometriosis and superficial dyspareunia treated with pelvic floor muscle physiotherapy: randomized controlled trial.

OBJECTIVES: Deep infiltrating endometriosis (DIE) is associated with chronic pelvic pain, dyspareunia and pelvic floor muscle hypertonia. The primary aim of this study was to evaluate the effect of pelvic floor physiotherapy (PFP) on the area of levator ani hiatus during Valsalva maneuver, assessed using transperineal ultrasound, in women with DIE suffering from superficial dyspareunia. METHODS: This was a randomized controlled trial of 34 nulliparous women diagnosed with DIE and associated superficial dyspareunia. After an initial clinical examination, all patients underwent three-dimensional/four-dimensional (3D/4D) transperineal ultrasound to measure the levator hiatal area (LHA) at rest, on maximum pelvic floor muscle contraction and on maximum Valsalva maneuver, and were asked to rate their pain symptoms using a numerical rating scale (NRS). Eligible women were assigned randomly (1:1 ratio) to no intervention (control group, 17 women) or treatment with five individual sessions of PFP (study group, 17 women). Four months after the first examination, all women underwent a second evaluation of pain symptoms and LHA on transperineal ultrasound. The primary outcome measure was the percentage change in LHA on maximum Valsalva maneuver between the baseline and follow-up examinations. The percentage changes in pain symptoms between the two examinations, including superficial and deep dyspareunia, dysmenorrhea, chronic pelvic pain, dysuria and dyschezia, were also evaluated. RESULTS: Thirty women, comprising 17 in the study group and 13 in the control group, completed the study and were included in the analysis. The percentage change in LHA on maximum Valsalva maneuver between the two examinations was higher in the study group than in the control group (20.0 ± 24.8% vs -0.5 ± 3.3%; P = 0.02), indicating better pelvic floor muscle relaxation. After PFP treatment, the NRS score for superficial dyspareunia remained almost unchanged in the control group (median change in NRS (Δ-NRS), 0 (interquartile range (IQR), 0-0)) while a marked reduction was observed in the study group (median Δ-NRS, -3 (IQR, -4 to -2); P < 0.01). Moreover, there was a significant difference between the PFP and control groups with regards to the change in chronic pelvic pain (median Δ-NRS, 0 (IQR, -2 to 0) vs 0 (IQR, 0-1); P = 0.01). CONCLUSIONS: In women with DIE, PFP seems to result in increased LHA on Valsalva maneuver, as observed by 3D/4D transperineal ultrasound, leading to improved superficial dyspareunia, chronic pelvic pain and pelvic floor muscle relaxation. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Pelvic floor muscle assessment on three- and four-dimensional transperineal ultrasound in women with ovarian endometriosis with or without retroperitoneal infiltration: a step towards complete functional assessment.

OBJECTIVES: Previous studies comparing women with deep infiltrating endometriosis (DIE) and healthy controls have underlined an association between pelvic floor muscle (PFM) hypertonic dysfunction and deep lesions. The aim of this study was to compare the morphometry of PFM in women affected by ovarian endometriosis with DIE vs those without DIE in order to assess the impact of retroperitoneal infiltration by the disease on PFM function. METHODS: This was a prospective study conducted between March 2015 and December 2016 on symptomatic women with a clinical and sonographic diagnosis of ovarian endometriosis with or without DIE, scheduled for laparoscopic surgery. We excluded patients with current or previous pregnancy, previous surgery for deep endometriosis, other causes of chronic pelvic pain or congenital or acquired abnormalities of pelvic floor anatomy. Three- and four-dimensional transperineal ultrasound was performed to evaluate PFM morphometry and assess levator hiatal area (LHA) and diameters at rest, during PFM contraction and during Valsalva maneuver. All volumes were analyzed offline by an investigator blinded to the clinical data. RESULTS: One hundred and fourteen patients with ovarian endometriosis were enrolled in the study, 75 with DIE and 39 without DIE. The diagnosis of endometriosis was confirmed by histological examination in all patients. Compared with women without DIE, women with DIE showed a smaller LHA at rest, during contraction and during Valsalva maneuver (P = 0.03, P = 0.03 and P = 0.02, respectively) and a smaller reduction in LHA during PFM contraction (P = 0.04). CONCLUSIONS: Women with ovarian endometriosis who were affected by DIE showed smaller hiatal dimensions than did women without DIE. Considering that PFM dysfunction in patients with DIE could cause pain symptoms and pelvic organ dysfunction, transperineal ultrasound could allow a more complete functional assessment and tailored therapy.

Letrozole combined with norethisterone acetate compared with norethisterone acetate alone in the treatment of pain symptoms caused by endometriosis.

BACKGROUND: The available data on effectiveness of aromatase inhibitors in treating pain symptoms related to endometriosis is limited. We compared the efficacy and tolerability of the aromatase inhibitor letrozole combined with norethisterone acetate versus norethisterone acetate alone in treating pain symptoms. METHODS: This prospective, open-label, non-randomized trial included 82 women with pain symptoms caused by rectovaginal endometriosis. Patients received either a combination of letrozole and norethisterone acetate (group L) or norethisterone acetate alone (group N) for 6 months. Changes in pain symptoms during treatment and in the 12 months of follow-up were evaluated. Side effects of each treatment protocol were recorded. RESULTS: Intensity of chronic pelvic pain and deep dyspareunia significantly decreased during treatment (P < 0.001 versus baseline by 3 months) in both study groups. At both 3- and 6-month assessment, the intensity of chronic pelvic pain (P < 0.001, P = 0.002, respectively) and deep dyspareunia (P < 0.001, P = 0.005, respectively) was significantly lower in group L than group N. At completion of treatment, 63.4% of women in group N were satisfied with treatment compared with 56.1% in group L (P = 0.49). Pain symptoms recurred after the completion of treatment; at 6-month follow-up no difference was observed in the intensity of pain symptoms between the groups. Adverse effects were more frequent in group L than in group N (P = 0.02). CONCLUSIONS: The combination drug regimen was more effective in reducing pain and deep dyspareunia than norethisterone acetate; however, letrozole caused a higher incidence of adverse effects, cost more and did not improve patients' satisfaction or influence recurrence of pain.

Financial impact in the Italian Health Service of laparoscopic versus laparotomic surgery for the treatment of ovarian cysts.

To assess the cost of two procedures for the removal of ovarian cysts, 200 pre-menopausal women were recruited for the surgical removal of ovarian cysts by laparoscopy (n = 100) and laparotomy (n = 100) according to case-control criteria. Patients operated by laparoscopy (mean age +/- SD 32.22 +/- 9.98 years) and laparotomy (mean age +/- SD 29.57 +/- 6.62 years) for ovarian cysts (mean diameters +/- SD 4.98 +/- 3.62 and 4.83 +/- 2.78 cm) had a post-surgical hospital stay of 3.12 +/- 0.41 and 7.25 +/- 1.08 days (P < 0.001) respectively. The total rate of complications occurring in patients operated by laparoscopy was 9 versus 53% (P < 0.001) of those operated by laparotomy; body temperature > 38 degrees C was recorded in 52/100 of patients operated by laparotomy versus 6/100 of those operated by laparoscopy. The mean cost for each pure surgical treatment performed by laparoscopy was US $498.17 versus US $642.47 when it was performed by laparotomy (P < 0.001). The laparoscopic surgical approach is more expensive in the first 36 operations, thereafter becoming cheaper. The mean of the entire overall expenditure was US $1142.08 and US $2138.72 for laparoscopy and laparotomy (P < 0.001) respectively. The entire expenditure for laparoscopy is higher than laparotomy only until eight operations. In conclusion, laparoscopy versus laparotomy has resulted in a saving of US $14,429.3 for 100 operations while the saving on entire costs was US $99,664.8.
