Minimally invasive surgery for ovarian endometriosis as a mean of improving fertility: Cystectomy vs. CO2 fiber laser ablation what do we know so far?

Minimally invasive surgery emerged in the 1980s as a safe and effective technique which requires smaller incisions and, usually, a shorter hospital stay compared to traditional surgery. Since then, minimally invasive surgery has expanded in many surgical specialties. One of its newest application in gynecology stands in the infertility management of young women with unexplained infertility or suspected endometriosis. In these cases, laparoscopy allows to diagnose and treat the disease aiming to increase at best the chances of spontaneous pregnancy or trough assisted reproductive technology. Nowadays, minimally invasive surgical approach of ovarian endometriosis consists of either laparoscopic cystectomy or ablative techniques such as laparoscopic CO2 fiber laser vaporization. Although cystectomy represents the gold standard according to the latest Cochrane review, some endometriosis experts are worried about its detrimental effect on healthy ovarian parenchyma and suggest preferring a less aggressive approach such as CO2 fiber laser vaporization. The aim of this review is to give an overview of the available evidences about the impact of the two surgical procedures on ovarian reserve markers and pregnancy outcome

Case report: optic atrophy and nephropathy with m.13513G>A/MT-ND5 mtDNA pathogenic variant

Isolated complex I deficiency represents the most common mitochondrial respiratory chain defect involved in mitochondrial disorders. Among these, the mitochondrial DNA (mtDNA) m.13513G>A pathogenic variant in the NADH dehydrogenase 5 subunit gene (MT-ND5) has been associated with heterogenous manifestations, including phenotypic overlaps of mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes, Leigh syndrome, and Leber’s hereditary optic neuropathy (LHON). Interestingly, this specific mutation has been recently described in patients with adult-onset nephropathy. We, here, report the unique combination of LHON, nephropathy, sensorineural deafness, and subcortical and cerebellar atrophy in association with the m.13513G>A variant

A Systematic Review of Atypical Endometriosis-Associated Biomarkers

Ovarian endometriosis may increase the risk of malignancy. Several studies have suggested atypical endometriosis as the direct precursor of endometriosis-associated ovarian cancer. We performed an advanced, systematic search of the online medical databases PubMed and Medline. The search revealed n = 40 studies eligible for inclusion in this systematic review. Of these, n = 39 were finally included. The results from included studies are characterized by high heterogeneity, but some consistency has been found for altered expression in phosphoinositide 3-kinase (PI3K)/AKT/mTOR pathway, ARID1a, estrogen and progesterone receptors, transcriptional, nuclear, and growth factors in atypical endometriosis. Although many targets have been proposed as biomarkers for the presence of atypical endometriosis, none of them has such strong evidence to justify their systematic use in clinical practice, and they all need expensive molecular analyses. Further well-designed studies are needed to validate the evidence on available biomarkers and to investigate novel serum markers for atypical endometriosis

The Impact on Ovarian Reserve of CO2 Laser Fiber Vaporization in the Treatment of Ovarian Endometrioma: A Prospective Clinical Trial:

Background In recent years, excisional surgery has been questioned as an ideal surgical approach for endometriomas because it is associated with potential removal of healthy ovarian tissue and loss of ovarian follicles with subsequent reduction of ovarian reserve. The aim of our study was to evaluate the benefits of CO2 laser vaporization through a clinical trial assessing the postoperative changes in ovarian reserve as indicated by antral follicle count (AFC) and anti-Müllerian hormone (AMH). Materials and Methods Fifteen patients undergoing surgery for primary unilateral or bilateral symptomatic endometriomas were enrolled in the study. During surgery, the cystic lining was completely vaporized with CO2 laser fiber (AcuPulse Duo system, Lumenis); before surgery and at 1 and 3 months after surgery, ovarian reserve was evaluated by pelvic ultrasound to determine the AFC, and blood sample to determine AMH levels. Results The AFC of the operated ovary was significantly increased after treatment at 1 and 3 months' follow-up (p = 0.0021; p = 0.005, respectively); the increase is particularly significant in women younger than 35 years (p = 0.012). No statistically significant changes were reported in serum AMH concentrations at 1 or 3 months' follow-up. No recurrences of symptoms and no recurrences of endometrioma were reported. Conclusions These data support the hypothesis that endometrioma vaporization with CO2 laser fiber may be a valid method to preserve ovarian function; however, further studies are required before advocating the routine use of CO2 laser vaporization for the management of ovarian endometriosis

Is the oocyte quality affected by endometriosis? A review of the literature

Abstract Endometriosis is an estrogen-dependent chronic inflammatory condition that affects women in their reproductive period causing infertility and pelvic pain. The disease, especially at the ovarian site has been shown to have a detrimental impact on ovarian physiology. Indeed, sonographic and histologic data tend to support the idea that ovarian follicles of endometriosis patients are decreased in number and more atretic. Moreover, the local intrafollicular environment of patients affected is characterized by alterations of the granulosa cell compartment including reduced P450 aromatase expression and increased intracellular reactive oxygen species generation. However, no comprehensive evaluation of the literature addressing the effect of endometriosis on oocyte quality from both a clinical and a biological perspective has so far been conducted. Based on this systematic review of the literature, oocytes retrieved from women affected by endometriosis are more likely to fail in vitro maturation and to show altered morphology and lower cytoplasmic mitochondrial content compared to women with other causes of infertility. Results from meta-analyses addressing IVF outcomes in women affected would indicate that a reduction in the number of mature oocytes retrieved is associated with endometriosis while a reduction in fertilization rates is more likely to be associated with minimal/mild rather than with moderate/severe disease. However, evidence in this field is still far to be conclusive, especially with regards to the effects of different stages of the disease and to the impact of patients’ previous medical/surgical treatment(s)

Vessel Wall MRI: clinical implementation in cerebrovascular disorders-technical aspects

Vessel Wall MRI (VW-MRI) is an emerging MR sequence used for diagnosis, characterization, and treatment planning of cerebrovascular diseases. Although VW-MRI is not yet routinely used, most papers have emphasized its role in several aspects of the management of cerebrovascular diseases. Nowadays, no VW-MRI sequence optimized for the intracranial imaging is commercially available, thus the Spin Echo sequences are the more effective sequences for this purpose. Moreover, as one of the principal technical requirements for intracranial VW-MR imaging is to achieve both the suppression of blood in vessel lumen and of the outer cerebrospinal fluid, different suppression techniques have been developed. This short report provides the technical parameters of our VW-MR sequence developed over 3-years' experience

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach

: The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice
