Robotic Surgery for Severe Endometriosis: A Preliminary Comparative Study of Cost Estimation.

STUDY OBJECTIVE: To compare the postoperative outcomes and the overall expenses between conventional laparoscopy and robotic surgery, in a series of consecutive patients managed for only severe endometriosis in our institute. DESIGN: A cohort comparative study. SETTING: Center of Excellence in Multidisciplinary Endometriosis Care. PATIENTS: A total of 175 symptomatic patients undergoing surgery for only severe endometriosis from March 2021 to August 2022. INTERVENTIONS: We treated patients with endometriosis involving the digestive tract such as rectum, sigmoid colon, and ileocecal junction by rectal shaving, discoid resection, or segmental resection (141 surgeries) with or without bladder (23 surgeries), sacral plexus (19 surgeries), and diaphragm involvements (14 surgeries). MEASUREMENTS AND MAIN RESULTS: Postoperative outcomes were evaluated in terms of total surgical time (total surgical room occupancy time and total operating time), hospitalization period, postoperative complications, rehospitalization, and second surgical procedures. A statistically higher total surgical room occupancy (203 minutes vs 151 minutes) and operating time (150 minutes vs 105 minutes) were observed in the robotic group (p = .001). No differences in terms of mean hospital stay (p = .06), postoperative complications (p = .91), rehospitalization (p = .48), and secondary surgical treatment (p = .78) were identified. Concerning the cost analysis only for disposable supply, the cost of colorectal resection was totaled at 2604 euros for the laparoscopic conventional approach vs 2957 euros for the robotic approach (+352.6 euros, +14%). The cost of rectal disc excision was 1527 euros for the laparoscopic conventional approach vs 1905.85 euros (+378 euros, +25%). CONCLUSIONS: Our study confirms the feasibility of the robotic approach for the treatment of severe endometriosis, with however a higher cost of robotic approach. Next studies should identify specific indications for robotic surgery, where technical advantages provided by the technology are followed by objective improvement of patients' outcomes.

Dienogest alone or dienogest combined with estrogens in the treatment of ovarian endometriomas, that is the question. A retrospective cohort study.

PURPOSE: to compare the effects of Dienogest 2 mg (D) alone or combined with estrogens (D + ethinylestradiol 0.03 mg, D + EE; D + estradiol valerate 1-3 mg, D + EV) in terms of symptoms and endometriotic lesions variations. METHODS: This retrospective study included symptomatic patients in reproductive age with ultrasound diagnosis of ovarian endometriomas. Medical therapy for at least 12 months with D, D + EE or D + EV was required. Women were evaluated at baseline visit (V1) and after 6 (V2) and 12 months (V3) of therapy. RESULTS: 297 patients were enrolled (156 in the D group, 58 in the D + EE group, 83 in the D + EV group). Medical treatment leaded to a significant reduction in size of endometriomas after 12 months, with no differences between the three groups. When comparing D and D + EE/D + EV groups, a significant decrease of dysmenorrhea was detected in the D group than in D + EE/D + EV group. Conversely, the reduction of dysuria was more significative in the D + EE/D + EV groups rather than in the D group. Regarding tolerability, treatment associated side effects were reported by 16.2% patients. The most frequent one was uterine bleeding/spotting, significantly higher in the D + EV group. CONCLUSION: Dienogest alone or associated with estrogens (EE/EV) seems to be equally effective in reducing endometriotic lesions mean diameter. The reduction of dysmenorrhea was more significative when D was administered alone, while dysuria seems to improve more when D is associated with estrogens.

Robotic management of isolated endometriosis of sciatic nerve: a reproducible approach that can guide through the labyrinth of pelvic neuroanatomy.

OBJECTIVE: To present the robotic, standardized, and reproducible surgical technique we routinely use in our center to manage isolated endometriosis of the sciatic nerve. DESIGN: Surgical video article. SETTING: Tertiary referral center. PATIENT: A 36-year-old woman suffering from left-sided sciatica pain was diagnosed with an isolated endometriotic nodule of the left sciatic nerve at preoperative assessment. The patient included in this video gave consent for publication of the video and posting of the video online, including on social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, and Scopus), and other applicable sites. INTERVENTION(S): Complete removal of the isolated endometriotic nodule of the sciatic nerve may be performed through a stepwise robotic approach. The surgery starts laterally with the opening of the iliolumbar space between the external iliac vessels and the psoas muscle, as well as the identification of the genitofemoral and obturator nerves. The lumbosacral trunk and emergence of the sciatic nerve were then identified medially and caudally to the obturator nerve. The surgery moves medially with the anterograde dissection of both the internal iliac artery and vein, which allows a safe approach to the posterior and medial limits of the nodule. Ligation of branches of internal iliac vessels directed toward the nodule may be necessary during this step. Isolation and ligation of obturator vessels are frequently required to obtain a bloodless dissection of the lateral limit of the nodule from the lateral pelvic wall. The complete removal of the nodule was then achieved using an alternating approach to all limits of the nodule previously identified, with subsequent release of the sciatic nerve. MAIN OUTCOME MEASURE(S): Description of the relevant pelvic neuroanatomy and the evaluation of robotic routes in the field of pelvic neurosurgery. RESULT(S): The use of standardized techniques together with the advantages of a robotic route can make the radical excision of isolated endometriosis of the sciatic nerve reproducible, feasible, and safe. CONCLUSION(S): Because of the complexity of neuroanatomy and the risk of severe complications, this surgery remains challenging, and patients affected by deep infiltrating endometriosis involving retroperitoneal neural structures should be referred to multidisciplinary management in expert centers.

Sonographic Assessment of Uterine Biometry for the Diagnosis of Diffuse Adenomyosis in a Tertiary Outpatient Clinic.

BACKGROUND: to compare several uterine biometric parameters at transvaginal ultrasound (TVUS) between adenomyosis and non-adenomyosis uteri and evaluate their role for the diagnosis of diffuse adenomyosis. METHODS: prospective observational study conducted between the 1 February 2022 and the 30 April 2022. In this case, 56 patients with TVUS diagnosis of adenomyosis were included. A 1:1 ratio age and parity-matched group of non-adenomyosis patients was selected. We compared sonographic uterine biometric parameters (longitudinal (LD), anteroposterior (APD) and transverse (TD) diameters, volume, simple and complex diameter ratios) and investigated their diagnostic performance. RESULTS: all sonographic parameters were significantly different between the study groups, except for TD/(LD+APD). Optimal cut-off values of APD and LD/APD showed the best sensitivity and specificity. APD diameter equal or superior to 39.5 mm (95% CI, 36.2-42.8) had sensitivity of 0.70 (95% CI, 0.57-0.80), specificity of 0.71 (95% CI, 0.59-0.82) and accuracy of 0.75 (95% CI, 0.66-0.84). LD/APD equal or inferior to 2.05 (95% CI, 1.96-2.13) showed sensitivity and specificity of 0.70 (95% CI, 0.57-0.80) each and accuracy of 0.72 (95% CI, 0.62-0.81). CONCLUSIONS: several biometric uterine parameters at TVUS in fertile-aged women were statistically different between adenomyosis and non-adenomyosis uteri, though their optimal cut-off values showed low accuracy in diagnosing adenomyosis.

The social media effect: the impact of fake news on women affected by endometriosis. A prospective observational study.

OBJECTIVES: Our purpose was to evaluate women's awareness of endometriosis and their ability to identify fake news about endometriosis on the internet. The second outcome was to identify those characteristics which make women more likely to believe in fake news. STUDY DESIGN: This prospective observational study was conducted at our academic outpatient clinic for endometriosis and pelvic pain. We enrolled 172 patients referred to our Center due to the suspicion of endometriosis, who were asked to fill in a two-part questionnaire. The first part included socio-demographic information, the evaluation of anxiety status (STAI Y6 and GAD-7), and endometriosis related-symptoms (EHP-5). The second part of the questionnaire was about fake news: women were asked whether they had encountered six different statings when searching the Internet, and to judge the likelihood that those 6 topics were true. RESULTS: 76.3% of patients found fake news about endometriosis online. Higher STAI-Y6 scores were associated with a higher risk of finding fake news about endometriosis (OR 1.05, 95% C.I. 1.01-1.09, p = 0.013). More than half of patients who came across the news regarding the impossibility of obtaining pregnancy for women affected by endometriosis considered this news moderately or highly credible, 6% of them even considered it completely plausible. No demographic characteristics were associated with thehigher perceived plausibility of the fake news. CONCLUSION: Gynecologists should be aware that some hot topics concerning endometriosis are widely talked about on the web and that many statements found online have no scientific base. Through this knowledge physicians could more easily engage patients by acquiring important insight into their main concerns and doubts, and could provide women with reliable and correct information regarding their disease, dissipating doubts and misconceptions.

Effects of the SARS-CoV-2 pandemic on women affected by endometriosis: a large cross-sectional online survey.

INTRODUCTION: The SARS-CoV-2 pandemic has forced healthcare providers to reorganize their activities to protect the population from infection, postponing or suspending many medical procedures. Patients affected by chronic conditions were among the most affected. In the case of catastrophes, women have a higher lifetime prevalence of post-traumatic stress disorder (PTSD), and those with endometriosis have higher anxiety levels, making them fragile in such circumstances. MATERIALS AND METHODS: In this cross-sectional study, conducted in May 2020, we considered all women aged ≥18 years, followed up at our referral centre for endometriosis. Patients were sent an anonymous 6-section questionnaire via email, containing different validated tools for the evaluation of anxiety levels and the risk of PTSD. A multivariable linear regression was performed to assess the impact of patients' characteristics on the distress caused by the SARS-COV-2 pandemic. RESULTS: Among the 468 women recruited, 68.8% were quite-to-extremely worried about not being able to access gynaecologic care, with almost one-third of them scoring ≥33 on the IES-R. Older age and increased levels of anxiety were associated with higher risks of PTSD (age: b = 0.28, 95% CI = 0.12 - 0.44; GAD-7: b = 1.71, 95% CI = 1.38 - 2.05), with up to 71.8% of patients with severe anxiety (GAD-7 > 15) having an IES-R score ≥33 suggestive for PTSD. Women who could leave home to work showed lower levels of PTSD (b = -4.79, 95% CI = -8.44 to - 1.15, ref. unemployed women). The implementation of telemedicine in routine clinical practice was favourably viewed by 75.6% of women. DISCUSSION: Women with endometriosis are particularly exposed to the risk of PTSD during the SARS-CoV-2 pandemic, especially if they are older or have higher levels of anxiety. Gynaecologists should resort to additional strategies, and telemedicine could represent a feasible tool to help patients cope with this situation.KEY MESSAGESThe COVID-19 pandemic significantly impacted the lives of women with endometriosis, who appeared to have a considerable risk of PTSD.Older age, higher anxiety levels and unemployment were independently associated with the risk of developing PTSD.Clinicians should develop successful alternative strategies to help patients cope with this situation, and telemedicine might represent an applicable and acceptable solution.

Conservative cesarean scar pregnancy treatment: local methotrexate injection followed by hysteroscopic removal with hysteroscopic tissue removal system.

OBJECTIVE: To describe a conservative cesarean scar pregnancy (CSP) treatment in a patient with the desire for future pregnancy. To date, there is no gold standard for the management of a viable CSP. There is a wide range of treatment options that include major surgery and minimally invasive procedures. Moreover, after a minimally invasive treatment, the gestational sac may be visible at ultrasound for >6 months. The described technique may be useful to avoid complications related to the use of energy with a large reduction in operative times. DESIGN: Description of the technique with narrated video footage. SETTING: Academic tertiary hospital. PATIENT(S): A 31-year-old woman with a previous cesarean section was referred to our clinic with lower abdominal pain. Transvaginal ultrasound revealed a gestational sac with a viable embryo located in the anterior isthmic region, suggestive of CSP at 9 weeks of gestation. Appropriate counseling describing the two diametrically opposite clinical management options was performed, and the patient decided to terminate the pregnancy. Informed consent was obtained from the patient. INTERVENTION(S): Hysteroscopy was performed under local anesthesia in an outpatient setting, using a 2.9-mm Hopkins II Forward-Oblique Telescope 30° endoscope (Karl Storz, Tuttlingen, Germany) with a 4.3-mm inner sheath and 5F instruments. A 3.7F needle (Deflux metal needle; Oceana Therapeutics, Edison, NJ) was pushed into the myometrial tissue surrounding the implantation site of the gestational sac at four different points. Six additional injections were performed into the gestational sac, and 50-mg methotrexate was injected. The appropriate follow-up was performed to determine the success of the procedure. ß-Human chorionic gonadotropin was dosed weekly until negative. After 6 weeks, to remove the avascular trophoblastic remnants found at ultrasound evaluation, the patient underwent hysteroscopic removal with a 6-mm TruClear hysteroscopic tissue removal system (Medtronic Parkway, Minneapolis, MN). A contemporary transabdominal ultrasound was performed to minimize surgical risks. MAIN OUTCOME MEASURE(S): Complete and conservative CSP treatment with the absence of surgical complications. RESULT(S): Conservative cesarean scar pregnancy treatment was performed successfully with primary local methotrexate injection followed, after 6 weeks, by hysteroscopic removal of the CSP remnants with the TruClear hysteroscopic tissue removal system. The first procedure lasted 6 minutes, whereas hysteroscopic removal of the CSP lasted 5 minutes. Both procedures were performed in an outpatient setting, and no complications were detected during and after the treatments. The patient reported good health at the 1-month follow-up visit, and the ultrasound showed an empty isthmocele (Fig. 1). CONCLUSION(S): Primary local methotrexate injection followed by hysteroscopic removal of the CSP remnants with the hysteroscopic tissue removal system may be a valuable treatment for women who desire pregnancy in the near future. This combined technique may avoid potential complications, such as thermal-induced myometrial injuries or uterine perforation. Moreover, the operator has the possibility to perform an under-vision procedure with a lower incidence of intraoperative and postoperative bleeding. Because it does not reduce fertility/pregnancy rate, this technique should be a valid option in patients who desire future pregnancy.

Management of Endometriomas.

Ovarian endometriomas affect 17 to 44% of women with endometriosis, and are often associated with pelvic pain and infertility. Treatment options include expectant management, medical and/or surgical treatment, and in vitro fertilization and embryo transfer (IVF-ET). The choice of treatment depends mostly on the associated symptoms. In most cases, surgery is the preferred choice, since endometriomas do not respond to medical treatment, which may only treat associated pain. In case of infertility, IVF-ET may be a suitable alternative to surgery, particularly when there is no associated pain. According to the best available scientific evidence, laparoscopic excision of the endometrioma wall should be considered the procedure of choice. Concerns have been raised as to the possibility that surgical excision may damage the ovarian reserve, but recent evidences demonstrate that part of the damage may be due to the presence of the endometrioma itself. Indication to surgical treatment should balance the possible risks of damaging the ovarian reserve with the advantages of surgery in terms of satisfactory pain relief rates and pregnancy rates, and of obtaining tissue specimen for ruling out the rare cases of unexpected ovarian malignancy. A score system to guide the clinician in the decision to perform or withhold surgery is presented.
