Mild endometriosis of the uterosacral ligaments: a retrospective study of magnetic resonance imaging performance for diagnosis.

RESEARCH QUESTION: What are the diagnostic performances of magnetic resonance imaging (MRI) scans when used to identify mild endometriosis of the uterosacral ligaments (USL)? DESIGN: Monocentric retrospective study of patients who underwent a pelvic MRI followed by laparoscopy for determination of endometriosis between January 2016 and December 2020. Patients were included whether endometriosis of USL was suspected or not, but patients presenting large lesions that left no doubt as to their endometriotic nature on the MRI were excluded. Six criteria for the description of USL on MRI were studied to determine their diagnostic performances in predicting the presence of endometriosis on laparoscopy as follows: asymmetry, thickening, irregularity, straightness, the presence of a nodule or a hypersignal T1 spot. RESULTS: Seventy-seven patients were included. Among the criteria, 'asymmetry' and 'thickening' had the highest sensitivities (0.69 [95% confidence interval 0.54-0.80] and 0.51 [0.40-0.63], respectively) but moderate specificities (0.52 [0.31-0.73] and 0.62 [0.50-0.72]). Conversely, 'irregularity', 'nodule', 'straightness' and 'hypersignal T1 spot' were associated with high specificities (0.81 [0.70-0.89], 0.96 [0.89-0.99], 0.95 [0.87-0.99] and 0.99 [0.93-1.00], respectively) but poor sensitivities (0.22 [0.14-0.33], 0.12 [0.06-0.21], 0.08 [0.03-0.16] and 0.08 [0.03-0.16], respectively). The presence of at least one criterion for the description of the USL was associated with good sensitivity (0.80 [0.66-0.89]) but poor specificity (0.35 [0.16-0.57]). CONCLUSIONS: The results suggest that the identification of minimal changes in the normal appearance of USL should not automatically lead to a conclusion of mild endometriosis at this location.

Using pneumovaginoscopy to perform the removal of a vaginal fibroid.

OBJECTIVE: To describe and assess the feasibility of a novel surgical technique (pneumovaginoscopy) for performing vaginal surgery. DESIGN: Video of a single surgical procedure. SETTING: A university hospital. PATIENT(S): A 42-year-old woman, gravida 2 para 2, presented with chronic pelvic pain. Vaginal examination revealed a 4-cm spherical mass bulging through her posterior vaginal wall. Magnetic resonance imaging identified this mass as either a subserosal pedunculated uterine fibroid (type 7 according to the FIGO classification) or an ectopic fibroid of the posterior vaginal wall (type 8). INTERVENTION(S): The whole procedure was performed using pneumovaginoscopy. The GelPOINT V-Path (Applied Medical, Rancho Santa Margarita, California) which is the device most often used to perform transvaginal natural orifice transluminal endoscopic surgical procedures, was introduced into the vagina to create a pneumovagina. Monopolar scissors were used to create an incision through the posterior vaginal wall to reach the fibroid. Myomectomy was performed using traction movements of the fibroid associated with the dissection of the capsule. The absence of a uterine pedicle at the end of the myomectomy was in favor of an ectopic fibroid of the vagina (type 8 of the FIGO classification). The vaginal defect was closed with interrupted sutures using the access points on the GelPOINT. MAIN OUTCOME MEASURE(S): The procedure was easily and efficiently performed using the pneumovaginoscopy technique and lasted less than an hour. The patient was discharged on postoperative day 1 without any postoperative complications. She was symptom-free at her 2-month postoperative visit. RESULT(S): Compared to the classical vaginal approach, pneumovaginoscopy improves visualization through targeted lighting and close-up vision. This technique is particularly interesting in cases where the vaginal opening is narrow and for lesions located in the upper half of the vagina. Because of the unusual expansion of the vagina, increased caution is required to avoid bladder or rectal injuries. CONCLUSION(S): Pneumovaginoscopy is a novel technique that can be performed for vaginal pathologies with the same device used for transvaginal natural orifice transluminal endoscopic surgery. We described this technique and assessed its feasibility.

Progression of adenomyosis magnetic resonance imaging features under ulipristal acetate for symptomatic fibroids.

RESEARCH QUESTION: What is the evolution of adenomyosis on magnetic resonance imaging (MRI) after a 3-month treatment course of daily 5 mg doses of ulipristal acetate (UPA) for symptomatic fibroids? DESIGN: A monocentric prospective pilot study on patients who underwent a 3-month treatment course of UPA for symptomatic fibroids between January 2014 and December 2017. Patients underwent pelvic MRI shortly before (pre-MRI) and after treatment (post-MRI). The diagnosis of adenomyosis on MRI was defined by the observation of intramyometrial cysts and/or haemorrhagic foci within these cystic cavities and/or a thickening of the junctional zone >12 mm. The progression of adenomyosis was defined by the presence of at least one of the aforementioned criteria of adenomyosis on the pre-MRI and by at least one of the following on the post-MRI: (i) increased thickness of the junctional zone ≥20% and/or (ii) increased number of intramyometrial cysts. The appearance of adenomyosis was defined by the absence of the aforementioned criteria of adenomyosis on the pre-MRI and the presence of at least one of these criteria on the post-MRI. RESULTS: Seventy-two patients were included. The MRI features of adenomyosis progressed for 12 of 15 patients (80.0%) for whom adenomyosis was identified on the pre-MRI. An appearance of adenomyosis was identified after treatment for 15 of 57 patients (26.3%) for whom adenomyosis was not identified on the pre-MRI. CONCLUSIONS: A 3-month treatment course of daily 5 mg doses of UPA could provoke a short-term progression or an emergence of typical adenomyosis intramyometrial cysts on MRI examinations.
