FEMaLe: The use of machine learning for early diagnosis of endometriosis based on patient self-reported data-Study protocol of a multicenter trial. PLoS One 2024; 19:e0300186. [PMID: 38722932 PMCID: PMC11081275 DOI: 10.1371/journal.pone.0300186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Accepted: 02/22/2024] [Indexed: 05/13/2024] Open
Abstract
INTRODUCTION Endometriosis is a chronic disease that affects up to 190 million women and those assigned female at birth and remains unresolved mainly in terms of etiology and optimal therapy. It is defined by the presence of endometrium-like tissue outside the uterine cavity and is commonly associated with chronic pelvic pain, infertility, and decreased quality of life. Despite the availability of various screening methods (e.g., biomarkers, genomic analysis, imaging techniques) intended to replace the need for invasive surgery, the time to diagnosis remains in the range of 4 to 11 years. AIMS This study aims to create a large prospective data bank using the Lucy mobile health application (Lucy app) and analyze patient profiles and structured clinical data. In addition, we will investigate the association of removed or restricted dietary components with quality of life, pain, and central pain sensitization. METHODS A baseline and a longitudinal questionnaire in the Lucy app collects real-world, self-reported information on symptoms of endometriosis, socio-demographics, mental and physical health, economic factors, nutritional, and other lifestyle factors. 5,000 women with confirmed endometriosis and 5,000 women without diagnosed endometriosis in a control group will be enrolled and followed up for one year. With this information, any connections between recorded symptoms and endometriosis will be analyzed using machine learning. CONCLUSIONS We aim to develop a phenotypic description of women with endometriosis by linking the collected data with existing registry-based information on endometriosis diagnosis, healthcare utilization, and big data approach. This may help to achieve earlier detection of endometriosis with pelvic pain and significantly reduce the current diagnostic delay. Additionally, we may identify dietary components that worsen the quality of life and pain in women with endometriosis, upon which we can create real-world data-based nutritional recommendations.

Clinical and ultrasound characteristics of deep endometriosis affecting sacral plexus. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2024. [PMID: 38315642 DOI: 10.1002/uog.27602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 12/03/2023] [Accepted: 01/24/2024] [Indexed: 02/07/2024]
Abstract
OBJECTIVES To describe sonomorphological changes and appearance of deep endometriosis (DE) affecting the nervous tissue of the sacral plexus (SP). METHODS This was a retrospective study of symptomatic female patients who underwent radical resection of histologically confirmed DE affecting the SP who had undergone preoperative transvaginal sonography (TVS). Between 2019 and 2023 lesions were described based on the terms and definitions of the International Deep Endometriosis Analysis (IDEA) group. DE affecting the SP was diagnosed on ultrasound by TVS, when sonographic criteria of DE were visualized in conjunction with fibers of the SP and the presence of related symptoms, so-called sacral radiculopathy. Clinical symptoms, ultrasound features and histological confirmation were analyzed for each patient included. RESULTS Twenty-seven patients with DE infiltrating the sacral plexus were identified in 2 contributing tertiary referral centers. Median age was 37 (range, 29-45) years and all of the patients were symptomatic and presented one or more of the following neurological symptoms: dysaesthesia in the ipsilateral lower extremity (n = 17), paraesthesia in the ipsilateral lower extremity (n = 10), chronic pelvic pain radiating in the ipsilateral lower extremity (n = 9), chronic pain radiating in the pudendal region (n = 8), weakness in the ipsilateral lower extremities (n = 3). All DE lesions affecting the SP were purely solid tumors in the posterior parametrium in direct contact with or infiltrating the S1 and/or S2 and/or S3 and/or S4 roots of the SP. The median of the largest diameter of the DE nodules was 35 mm and echogenicity of the DE nodules was in 86% (n=23) non-uniform. All but one of them contained hyperechoic areas. The shape of the lesions was in 89% (n=24)irregular. Only one lesion exhibited lobulated form, all other irregular lesion showed spiculated appearance. 74% (n=20) of the nodules gave an acoustic shadow, all of them internal. With color or power Doppler examination 78% (n=21) of the nodules showed no signal (Color Score 1). The remaining 22% (n=6) of the lesions manifested only a minimal color content (Color Score 2). According to pattern recognition, most DE nodules were a purely solid non-uniform hypoechoic nodule with hyperechoic areas, internal shadows and irregular spiculated contours and poorly vascularized at color/power Doppler examination. CONCLUSION The ultrasound finding of a parametrial unilateral solid non-uniform hypoechoic nodule with hyperechoic areas and possible internal shadowing as well as irregular spiculated contours demonstrating poor vascularization on Doppler examination in proximity or involving the structures of the SP reflects DE affecting these structures.

Abstract
OBJECTIVES To test the accuracy of TVS applying the IDEA approach for suspected rectosigmoid DE and to determine the frequency of other pelvic diseases mimicking DE in patients undergoing surgery. MATERIALS UND METHODS Prospective single center observational study including consecutive women undergoing TVS for clinically suspected rectosigmoid DE followed by conservative or surgical therapy. TVS findings were compared with those obtained by laparoscopy and confirmed histologically. RESULTS Of the 671 included patients, 128 women opted for medical therapy, and 6 patients decided for surgery but did not give consent to participate in the study. 537 women were enrolled in the final analysis. 279 (52 %) exhibited surgically confirmed rectosigmoid DE. The sensitivity and specificity, positive and negative predictive value (PPV, NPV), positive and negative likelihood ratio (LR+/-) and accuracy of TVS for diagnosing DE in the rectosigmoid were 93.5 %, 94.6 %, 94.9 %, 93.1 %, 17.24, 0.07, 94.04 %. 12 women who were clinically suspected for DE and mimicked sonographic signs fulfilling the IDEA criteria did exhibit other pathologies. Diagnoses were as follows: vaginal Gartner duct cyst (3/291;1.0 %), anorectal abscess (3/291; 1.0 %), rectal cancer (2/291;0.7 %), hydrosalpinx (2/291;0.7 %), metastatic endometrial cancer (1/291;0.35 %) and Crohn's disease (1/291;0.35 %). CONCLUSION TVS for diagnosing colorectal DE applying the IDEA criteria is highly accurate for presurgical diagnosis. However, additional pelvic pathologies are encountered in 4-5 % of women attending for suspected rectosigmoid DE. These need to be taken into account when investigating patients for suspected DE.

Laparoscopic natural orifice specimen extraction colectomy versus conventional laparoscopic colorectal resection in patients with rectal endometriosis: a randomized, controlled trial. Int J Surg 2023; 109:4018-4026. [PMID: 37720929 PMCID: PMC10720833 DOI: 10.1097/js9.0000000000000728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 08/21/2023] [Indexed: 09/19/2023]
Abstract
BACKGROUND The conventional laparoscopic approach for the surgical management of deep endometriosis (DE) infiltrating the rectum appears to ensure improved digestive functional outcomes. The natural orifice specimen extraction (NOSE) technique for the treatment of colorectal DE can significantly accelerate postoperative recovery; however, data on gastrointestinal function following conventional laparoscopic segmental bowel resection (CLR) compared with NOSE colectomy (NC) for DE are sparse. MATERIALS AND METHODS Between 30 September 2019 and 31 December 2020, a randomized, open-label, two-arm, parallel-group controlled trial with women aged 18-45 years was conducted at University Hospital.Ninety-nine patients were randomized to CLR or NC, with DE infiltrating at least the muscular layer, at least 50% of the circumference of the bowel, up to 15 cm from the anal verge, exhibiting pain and bowel symptoms and/or infertility. The primary endpoint was bowel function, represented by low anterior resection syndrome (LARS). Secondary parameters included the Endometriosis Health Profile 30 (EHP30), Gastrointestinal Quality of Life Index (GIQLI), Visual Analog Scale (VAS) scores preoperatively and at set times (1 and 6 months, 1 year) following surgery. RESULTS No significant differences were observed in the postoperative LARS scores, VAS, EHP30, and GIQLI between the NC and CLR groups. LARS scores did not reveal significant differences 12 months postoperatively compared to the preoperative values in both groups (CLR group P =0.93 versus NC group, P =0.87). GIQLI scores were significantly improved 12 months after the operation compared with baseline values in the CLR group ( P =0.002) and NC group ( P =0.001). Pain symptoms and quality of life scores significantly improved 12 months postoperatively in both groups. CONCLUSIONS NC is a feasible surgical approach for treating patients with rectal DE. Our study did not show a statistically significant difference between CLR and NC techniques in mid-term digestive and pain outcomes.

Pain, gastrointestinal function and fertility outcomes of modified nerve-vessel sparing segmental and full thickness discoid resection for deep colorectal endometriosis - A prospective cohort study. Acta Obstet Gynecol Scand 2023; 102:1347-1358. [PMID: 37694901 PMCID: PMC10541157 DOI: 10.1111/aogs.14676] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 08/19/2023] [Accepted: 08/21/2023] [Indexed: 09/12/2023]
Abstract
INTRODUCTION There is an ongoing debate on surgical techniques for colorectal deep endometriosis (DE) and their effects on gastrointestinal (GI) function. The aim of this study was to prospectively investigate the differences in pre- and postsurgical GI function, health profiles and pain symptoms in women undergoing colorectal surgery for symptomatic DE either with a modified segmental resection technique, so-called nerve-vessel sparing segmental resection (NVSSR), or full thickness discoid resection (FTDR). Complication rates and fertility outcomes were also evaluated. MATERIAL AND METHODS A total of 162 consecutive patients, 125 (77.2%) of whom underwent NVSSR and 37 (22.8%) FTDR, were evaluated regarding complication rates. Furthermore a lower anterior resection syndrome (LARS) scores, gastrointestinal function-related quality of life index (GIQLI), pain symptoms, endometriosis health profile (EHP-30) parameters were analyzed pre- and post-surgery in a final cohort of 121 patients. RESULTS There was no difference between postsurgical prevalence of LARS in either surgery group (14/98, 14.1% NVSSR; 2/23, 8.6% FTDR), with significantly decreased LARS scores and increased GIQLI values before vs after surgery in both groups (P < 0.001). The overall grade III complication rate was 7/162 (4.3%) with no significant differences between NVSSR and FTDR groups. Overall, EHP-30 and pain scores significantly decreased after a median follow-up of 41 (± 17.6) months (EHP-30 51.1, SD 21.5 vs 12.7, SD 19.3, P < 0.001; dysmenorrhea, dyspareunia, dyschezia all P < 0.001 both cohorts, respectively). The overall life birth rate and postsurgical pregnancy in infertile patients undergoing NVSSR and FTDR was respectively 58.1% in 25/43 patients; 55.6% in 5/9 patients; 56.0% in 14/25 patients and 100% in 5/5 patients. CONCLUSIONS NVSSR and FTDR for symptomatic colorectal DE confer a significant amelioration of GI function reflected by decreased LARS symptoms and increased GIQLI scores with no differences in postsurgical function in between the two techniques. Both techniques confer similar complication rates and effects on pain reduction and health profiles.

Abstract
OBJECTIVE To investigate the feasibility of identifying and measuring the normal sacral plexus (SP) on gynecological transvaginal ultrasound (TVS) examination. METHODS This was a prospective observational study conducted at a single tertiary gynecological referral center, including consecutive women undergoing TVS for various indications between November 2021 and January 2022. A standardized assessment of the pelvic organs was performed and the presence of any congenital or acquired uterine pathology or ovarian abnormality was recorded. Visualization of the right and left SP was attempted in all cases. The success rate and the time needed to identify the SP were recorded and measurements of the SP were made. RESULTS A total of 326 patients were included in the study. In all women, the SP was identified successfully on at least one side. SP were visualized bilaterally in 317 (97.2% (95% CI, 94.4-98.5%)) women. Only the right SP was seen in 3/326 (0.9% (95% CI, 0.2-2.7%)) and only the left in 6/326 (1.8% (95% CI, 0.6-4.0%)) (P = 0.5048). There was no significant difference in the median time required to visualize the right vs left SP (9.0 (interquartile range (IQR), 8.0-10.0) s vs 9.0 (IQR, 8.0-10.0) s; P = 0.0770). The median transverse diameter of the right SP was 15.0 (IQR, 14.2-15.6) mm and that of the left SP was 14.9 (IQR, 14.4-15.6) mm. CONCLUSIONS We describe a novel method which allows for the consistent and rapid identification of the SP on TVS. Integrating assessment of the SP into routine pelvic TVS may be helpful particularly for women suffering from deep endometriosis. © 2023 The Authors.

Variable fragment length allele-specific polymerase chain reaction (VFLASP), a method for simple and reliable genotyping. Mol Cell Probes 2023; 69:101910.

Abstract
Single-nucleotide polymorphism (SNP) is a substitution of a single nucleotide at a specific position in the genome. Until now, 585 million SNPs have been identified in the human genome, and therefore, a widely applicable method is desirable to detect a specific SNP. Herein we report a simple and reliable genotyping assay, which seems to be suitable for medium and small size laboratories, as well, to easily genotype most of the SNPs. In our study, all of the possible base variations (A-T, A-G, A-C, T-G, T-C, G-C) were tested to prove the general feasibility of our technique. The basis of the assay is a fluorescent PCR, in which both allele-specific primers, differing only at the 3' end according to the sequence of the SNP, were present, and the length of one of them was modified with 3 bp by adding an adapter sequence to the 5' end of that primer. The competitive presence of both allele-specific primers excludes the false amplification of the absent allele (which can happen in simple allele-specific PCR (AS-PCR)) and ensures the amplification of the proper allele(s). Unlike other complicated genotyping methods that use of manipulation of fluorescent dyes for genotyping, we apply an approach based on the length of amplicons from different alleles to differentiate between them. In our experiment (named variable fragment length allele-specific polymerase chain reaction (VFLASP)), the investigated six SNP, containing the six available base variations, gave clear and reliable results after detecting the amplicons by capillary electrophoresis.

Abstract
INTRODUCTION Deep infiltrating endometriosis penetrates the peritoneal surface beneath 5 mm. The bowel is affected in 3-37% of the cases. OBJECTIVE The aim of the authors was to analyze the results of the surgical procedures performed for bowel endometriosis. METHOD Between 2009 and 2020, 675 patients underwent bowel endometriosis surgery at the Department of Obstetrics and Gyanecology of Semmelweis University. Four surgical approaches were performed: shaving, discoid, segmental and NOSE resection. RESULTS 182 shaving, 93 discoid, 130 NOSE and 270 segmental bowel resections were performed. Ultra-deep anastomosis was performed in 40 cases. The median operative time was 85 minutes, the shortest intervention lasted 25 minutes, the longest 585 minutes. The average operating time was 260 (± 161.3) minutes for the first, and 114 (± 47.0) minutes for the last ten operations. The average blood loss was 10 (± 20.3) mL. The average hospital stay was 6 (± 2.3) days. Serious surgical complication (Clavien-Dindo III or more severe) developed in 18 cases. In a total of 17 cases sigmoideo- or ileostomy were used. Conversion to laparotomy was necessary in 6 cases. DISCUSSION The same team performed all the interventions, which can show the effectiveness of the surgical techniques instead of the technique of individual surgeons. The complication rate is low in the case of an experienced surgical team, and the operating time decreases significantly in proportion to the number of operations performed. CONCLUSION Bowel endometriosis can be treated safely and effectively with both conservative (shaving or discoid) and radical (segmental or NOSE resection) approach. Orv Hetil. 2023; 164(9): 348-354.

Abstract
STUDY QUESTION How is endometriosis extent described by the #Enzian classification compared to the revised American Society for Reproductive Medicine (rASRM) stages in women undergoing radical surgery for deep endometriosis (DE)? SUMMARY ANSWER The prevalence and severity grade of endometriotic lesions and adhesions as well as the total number of #Enzian compartments affected by DE increase on average with increasing rASRM stage; however, DE lesions are also present in rASRM stages 1 and 2, leading to an underestimation of disease severity when using the rASRM classification. WHAT IS KNOWN ALREADY Endometriotic lesions can be accurately described regarding their localization and severity by sonography as well as during surgery using the recently updated #Enzian classification for endometriosis. STUDY DESIGN, SIZE, DURATION This was a prospective multicenter study including a total of 735 women between January 2020 and May 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS Disease extent in women undergoing radical surgery for DE at tertiary referral centers for endometriosis was intraoperatively described using the #Enzian and the rASRM classification. MAIN RESULTS AND THE ROLE OF CHANCE A total of 735 women were included in the study. Out of 31 women with rASRM stage 1, which is defined as only minimal disease, 65% (i.e. 20 women) exhibited DE in #Enzian compartment B (uterosacral ligaments/parametria), 45% (14 women) exhibited DE in #Enzian compartment A (vagina/rectovaginal septum) and 26% (8 women) exhibited DE in #Enzian compartment C (rectum). On average, there was a progressive increase from rASRM stages 1-4 in the prevalence and severity grade of DE lesions (i.e. lesions in #Enzian compartments A, B, C, FB (urinary bladder), FU (ureters), FI (other intestinal locations), FO (other extragenital locations)), as well as of endometriotic lesions and adhesions in #Enzian compartments P (peritoneum), O (ovaries) and T (tubo-ovarian unit). In addition, the total number of #Enzian compartments affected by DE lesions on average progressively increased from rASRM stages 1-4, with a maximum of six affected compartments in rASRM stage 4 patients. LIMITATIONS, REASONS FOR CAUTION Interobserver variability may represent a possible limitation of this study. WIDER IMPLICATIONS OF THE FINDINGS The #Enzian classification includes the evaluation of DE in addition to the assessment of endometriotic lesions and adhesions of the ovaries and tubes and may therefore provide a comprehensive description of disease localization and extent in women with DE. STUDY FUNDING/COMPETING INTEREST(S) No funding was received for this study. All authors declare that they have no conflict of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
INTRODUCTION The aim of this study was to analyze the available literature by conducting a systematic review to assess the possible effects of nerve-sparing segmental resection and conventional bowel resection on postoperative complications for the treatment of colorectal endometriosis. MATERIAL AND METHODS Pubmed, Clinical Trials.gov, Cochrane Library, and Web of Science were comprehensively searched from 1997 to 2021 in order to perform a systematic review. Studies including patients undergoing segmental resection for colorectal endometriosis including adequate follow-up, data on postoperative complications and postoperative sequelae were enrolled in this review. Selected articles were evaluated and divided in two groups: Nerve-sparing resection (NSR), and conventional segmental resection not otherwise specified (SRNOS). Within the NSRs, studies mentioning preservation of the rectal artery supply (artery and nerve-sparing SR - ANSR) and not reporting preservation of the artery supply (NSR not otherwise specified - NSRNOS) were further analyzed. PROSPERO ID CRD42021250974. RESULTS A total of 7549 patients from 63 studies were included in the data analysis. Forty-three of these publications did not mention the preservation or the removal of the hypogastric nerve plexus, or main rectal artery supply and were summarized as SRNOS. The remaining 22 studies were listed under the NSR group. The mean size of the resected deep endometriosis lesions and patients' body mass index were comparable between SRNOS and NSR. A mean of 3.6% (0-16.6) and 2.3% (0-10.5%) of rectovaginal fistula development was reported in patients who underwent SRNOS and NSR, respectively. Anastomotic leakage rates varied from 0% to 8.6% (mean 1.7 ± 2%) in SRNOS compared with 0% to 8% (mean 1.7 ± 2%) in patients undergoing NSR. Urinary retention (4.5% and 4.9%) and long-term bladder catheterization (4.9% and 5.6%) were frequently reported in SRNOS and NSR. There was insufficient information about pain or the recurrence rates for women undergoing SRNOS and NSR. CONCLUSIONS Current data describe the outcomes of different segmental resection techniques. However, the data are inhomogeneous and not sufficient to reach a conclusion regarding a possible advantage of one technique over the other.

Abstract
Study question
What is the impact of laparoscopic conventional or NOSE colorectal resection on bowel function in patients with deep endometriosis infiltrating the rectum one year postoperatively?
Summary answer
Both conventional and NOSE colectomy improved the functional outcomes and quality of life among patients with deeply invasive rectal endometriosis one year after bowel surgery.
What is known already
Conventional laparoscopic approach to the surgical management of deep endometriosis infiltrating the rectum appears to assure improved digestive functional outcomes. NOSE technique for colorectal disease can significantly reduce the duration of hospital stay, accelerate postoperative recovery with better cosmetic results, and in particular, result in less postoperative pain and fewer complications. However, long-term solid data about gastrointestinal well-being after segmental bowel or NOSE resection for deep endometriosis are still missing.
Study design, size, duration
Between the 1st September 2019 - 31th of December 2020 we performed a 2-arm unblinded prospective randomized trial, enroling 91 patients with deep infiltrating rectal endometriosis up to 15 cm from the anal verge. Patients aged between 18 and 45 years, with deep endometriosis infiltrating at least the muscular layer in depth, and up to 50% of rectal circumference, complaining pain, bowel symptoms and/or infertility were included. The average follow up time was 14±2.6 months.
Participants/materials, setting, methods
Patients were enroled at Semmelweis University, Department of Obstetrics and Gynecology, Budapest, Hungary and had either conventional laparoscopic bowel resection or NOSE resection. Randomization was performed preoperatively using the simple randomization method. The primary endpoint was to assess the bowel function and quality of life by using the Endometriosis Health Profile 30, the Gastrointestinal Quality of Life Index and the Low Anterior Resection Syndrome score preoperatively, 1 month, 6 months, 1 year after the surgery.
Main results and the role of chance
A total of 91 patients were enroled. 39 patients were in the NOSE surgery arm, 49 were in the Conventional laparoscopic surgery arm. One patient was lost to follow-up and we had two cases of drop out from the trial after randomization due to performing non intended disc resection. This cases were excluded from the study. There was no conversion to laparotomy.The overall scores on Gastrointestinal Quality of Life Index (GIQLI), Low Anterior Resection Syndrome scores (LARS) and Endometriosis Health Profile 30 (EHP30) scores did not reveal significant differences between the two groups. LARS scores were improved, but did not reveal significant differences 12 months (T3) after the operation compared with the preoperative (T0) values in both groups (Conventional surgery group: T0=21.41 T3= 17.90; p = 0.934, NOSE surgery goup T0= 26.53 T3= 18.23; p = 0.229). GIQLI scores were significantly improved 12 months after the operation compared with the baseline values in Conventional surgery group T0= 95.44 T3= 111.39 p = 0.002. EHP30 scores were significantly improved concerning pain, emotion well-being, control and powerlessness, self-image, social support and sexuality scale 12 months after the operation compared with the preoperative values in both groups.
Limitations, reasons for caution
An obvious bias of performance is the lack of blinding, however blinding was not feasible due to the clinical nature of our study. We report no imprecision in patient selection, but a potential source of attrition bias in our data occured in a total number of three cases in NOSE-group.
Wider implications of the findings
Our study does not show a statistically significant difference between conventional or NOSE surgery for short and mid-term functional digestive outcomes. Occurrence of longterm bowel dysfunction does not appear to be related to a specific surgical technique.

Abstract
Abstract
In 2005, under the auspices of ESHRE, a group of international experts evaluated the existing best evidence and published the first European guideline on the management of endometriosis. This highly successful project was the first guideline by ESHRE and was adopted by many counties as their national standard. A second, fully-updated edition was presented in 2013.
For the new ESHRE Endometriosis Guideline, published in February 2022, all available evidence for twelve chosen topics was gathered by a senior research specialist. Subgroups comprised of patient representatives and experts in healthcare, reproductive science and epidemiology evaluated the data according to GRADE criteria. Each subgroup wrote a chapter and formulated their recommendations which were then presented by a representative to the core group. There, a provisional document was generated and made available for stakeholder review. The resulting comments were taken into account and where relevant incorporated into the final guideline document for which approval was sought and gained from the ESHRE Executive Committee.
35 PICO (Patients, Interventions, Comparison, Outcome) and seven narrative questions were addressed resulting in 78 Research Recommendations were formulated. Where sufficient scientific evidence was lacking and the Guideline Development Group (GDG) was of the opinion that an important topic needed to be highlighted Good Clinical Practice Points where created based on experts’ experience.
During the process of reviewing the literature it became apparent that large knowledge gaps of the best clinical approach to endometriosis exist. As a result, 30 research recommendations were also produced.
One of the main differences to the 2013 version of the ESHRE guidelines is that laparoscopy is no longer the gold standard for endometriosis per se as there exist sufficient data to support the use of transvaginal ultrasound performed by an experienced operator or MRI can equally identify or rule out ovarian and most of deep endometriosis. However, it is recognised by the GDG that the required imaging standards are not ubiquitously available and for peritoneal disease both sensitivity and specificity using either imaging modalities are still poor. As opposed to the 2013 recommendation, the GDG does not anymore recommend an ultralong protocol for the women with rASRM stage III/IV endometriosis to improve IVF success rates. Furthermore, gonadotropin releasing hormone antagonists seem to be effective in the treatment of endometriosis-associate pain and, where available, could be considered as second-line treatment.
Other changes were specific chapters on endometriosis in adolescents and in menopausal women as the GDG strongly felt that these groups are concerningly underrepresented in clinical care and research. Finally, a chapter focussing on the association of endometriosis with certain forms of cancer namely subgroups of ovarian cancer, breast and thyroid cancer was added to give both patients and clinicians a better insight into the current evidence of this complex topic.
The GDG hope that the new ESHRE Endometriosis Guideline will improve the clinical management of a highly prevalent and heterogenous disease and that the freely-available patient-friendly version of the guideline empowers symptomatic and asymptomatic women to seek the best available advice, support and treatment.

Accuracy of sonography for non-invasive detection of ovarian and deep endometriosis using #Enzian classification: prospective multicenter diagnostic accuracy study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 59:385-391. [PMID: 34919760 DOI: 10.1002/uog.24833] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 11/30/2021] [Accepted: 12/01/2021] [Indexed: 06/14/2023]
Abstract
OBJECTIVE To compare the preoperative detection of endometriosis using transvaginal sonography (TVS) supplemented by transabdominal sonography (TAS) with surgical assessment of disease, using the #Enzian classification for endometriosis. METHODS This was a prospective multicenter diagnostic accuracy study of women undergoing TVS/TAS and radical surgery for deep endometriosis (DE) at different tertiary referral centers. The localization and grade of severity of the endometriotic lesions and adhesions were described according to the criteria of the #Enzian classification, both at preoperative ultrasound examination and during surgery. According to the #Enzian classification, the small pelvis is divided into three compartments for DE: A (rectovaginal septum and vagina); B (uterosacral and cardinal ligaments, parametrium and pelvic sidewalls); and C (rectum). In addition, further locations (F) are classified as adenomyosis (FA), urinary bladder involvement (FB) and ureteric involvement with signs of obstruction (FU). Other intestinal locations (FI) and other extragenital locations (FO) are also included. Ovarian endometriosis and adhesions at the level of the tubo-ovarian unit are listed as O and T, respectively. The #Enzian grade of severity (Grade 1-3) was determined for #Enzian compartments O, T, A, B and C based on the size of the lesion or the severity of the adhesions. Concordance between preoperative assessment using TVS/TAS and evaluation at surgery was assessed. The sensitivity, specificity, positive and negative predictive values and accuracy of TVS/TAS in the detection of endometriotic lesions/adhesions in the different #Enzian compartments were calculated. RESULTS In total, 745 women were included in the analysis. Preoperative TVS/TAS and surgical findings showed a concordance rate ranging between 86% and 99% for the presence or absence of endometriotic lesions/adhesions, depending on the evaluated #Enzian compartment. The concordance rate between TVS and surgery ranged between 71% and 92% for different severity grades, in #Enzian compartments O, T, A, B and C. Determining the presence or absence of adhesions at the level of the tubo-ovarian unit and classifying them accurately as Grade 1, 2 or 3 on TVS was more difficult than determining the presence and severity of endometriotic lesions in #Enzian compartments O, A, B and C. The sensitivity of TVS/TAS for the detection of endometriotic lesions ranged from 50% (#Enzian compartment FI) to 95% (#Enzian compartment A), specificity from 86% (#Enzian compartment Tleft ) to 99% (#Enzian compartment FI) and 100% (#Enzian compartments FB, FU and FO), positive predictive value from 90% (#Enzian compartment Tright ) to 100% (#Enzian compartment FO), negative predictive value from 74% (#Enzian compartment Bleft ) to 99% (#Enzian compartments FB and FU) and accuracy from 88% (#Enzian compartment Bright ) to 99% (#Enzian compartment FB). CONCLUSIONS The localization and severity of endometriotic lesions/adhesions, as described and classified according to the #Enzian classification, can be diagnosed accurately and non-invasively using TVS/TAS. The #Enzian classification provides a uniform classification system for describing endometriotic lesions, which can be used both at TVS/TAS and during surgical evaluation. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
STUDY QUESTION How should endometriosis be diagnosed and managed based on the best available evidence from published literature? SUMMARY ANSWER The current guideline provides 109 recommendations on diagnosis, treatments for pain and infertility, management of disease recurrence, asymptomatic or extrapelvic disease, endometriosis in adolescents and postmenopausal women, prevention and the association with cancer. WHAT IS KNOWN ALREADY Endometriosis is a chronic condition with a plethora of presentations in terms of not only the occurrence of lesions, but also the presence of signs and symptoms. The most important symptoms include pain and infertility. STUDY DESIGN SIZE DURATION The guideline was developed according to the structured methodology for development of ESHRE guidelines. After formulation of key questions by a group of experts, literature searches and assessments were performed. Papers published up to 1 December 2020 and written in English were included in the literature review. PARTICIPANTS/MATERIALS SETTING METHODS Based on the collected evidence, recommendations were formulated and discussed within specialist subgroups and then presented to the core guideline development group (GDG) until consensus was reached. A stakeholder review was organized after finalization of the draft. The final version was approved by the GDG and the ESHRE Executive Committee. MAIN RESULTS AND THE ROLE OF CHANCE This guideline aims to help clinicians to apply best care for women with endometriosis. Although studies mostly focus on women of reproductive age, the guideline also addresses endometriosis in adolescents and postmenopausal women. The guideline outlines the diagnostic process for endometriosis, which challenges laparoscopy and histology as gold standard diagnostic tests. The options for treatment of endometriosis-associated pain symptoms include analgesics, medical treatments and surgery. Non-pharmacological treatments are also discussed. For management of endometriosis-associated infertility, surgical treatment and/or medically assisted reproduction are feasible. While most of the more recent studies confirm previous ESHRE recommendations, there are five topics in which significant changes to recommendations were required and changes in clinical practice are to be expected. LIMITATIONS REASONS FOR CAUTION The guideline describes different management options but, based on existing evidence, no firm recommendations could be formulated on the most appropriate treatments. Also, for specific clinical issues, such as asymptomatic endometriosis or extrapelvic endometriosis, the evidence is too scarce to make evidence-based recommendations. WIDER IMPLICATIONS OF THE FINDINGS The guideline provides clinicians with clear advice on best practice in endometriosis care, based on the best evidence currently available. In addition, a list of research recommendations is provided to stimulate further studies in endometriosis. STUDY FUNDING/COMPETING INTERESTS The guideline was developed and funded by ESHRE, covering expenses associated with the guideline meetings, with the literature searches and with the dissemination of the guideline.

Challenges of and possible solutions for living with endometriosis: a qualitative study. BMC Womens Health 2022; 22:20. [PMID: 35081940 PMCID: PMC8793269 DOI: 10.1186/s12905-022-01603-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 01/14/2022] [Indexed: 12/11/2022] Open
Abstract
Background Endometriosis as a chronic gynecological disease has several negative effects on women’s life, thereby placing a huge burden on the patients and the health system. The negative impact of living with endometriosis (impaired quality of life, diverse medical experiences) is detailed in the literature, however, we know less about patients’ self-management, social support, the meaning of life with a chronic disease, and the needs of patients. To implement a proper multidisciplinary approach in practice, we need to have a comprehensive view of the complexity of endometriosis patients’ life and disease history. Methods Four focus group discussions were conducted between October 2014 and November 2015 by a team consisting of medical and psychological specialists. 21 women (age: 31.57; SD = 4.45) with surgical and histological confirmation of endometriosis were included in the study. Discussions were audiotaped and transcribed verbatim, and a 62,051-word corpus was analyzed using content analysis. Results Four main themes emerged from the analysis: (1) the impact of endometriosis on quality of life, (2) medical experiences, (3) complementary and alternative treatments, and (4) different coping strategies in disease management. All themes were interrelated and highly affected by a lack of information and uncertainty caused by endometriosis. A supporting doctor-patient relationship, active coping, and social support were identified as advantages over difficulties. Finding the positive meaning of life after accepting endometriosis increased the possibility of posttraumatic growth. Furthermore, women’s needs were identified at all levels of the ecological approach to health promotion. Conclusions Our results highlight the need for multidisciplinary healthcare programs and interventions to find solutions to the difficulties of women with endometriosis. To achieve this goal, a collaboration of professionals, psychologists, and support organizations is needed in the near future.

The #Enzian classification: A comprehensive non-invasive and surgical description system for endometriosis. Acta Obstet Gynecol Scand 2021; 100:1165-1175.

Abstract
Advances in preoperative diagnostics as well as in surgical techniques for the treatment of endometriosis, especially for deep endometriosis, call for a classification system, that includes all aspects of the disease such as peritoneal endometriosis, ovarian endometriosis, deep endometriosis, and secondary adhesions. The widely accepted revised American Society for Reproductive Medicine classification (rASRM) has certain limitations because of its incomplete description of deep endometriosis. In contrast, the Enzian classification, which has been implemented in the last decade, has proved to be the most suitable tool for staging deep endometriosis, but does not include peritoneal or ovarian disease or adhesions. To overcome these limitations, a comprehensive classification system for complete mapping of endometriosis, including anatomical location, size of the lesions, adhesions and degree of involvement of the adjacent organs, that can be used with both diagnostic and surgical methods, has been created through a consensus process and will be described in detail-the #Enzian classification.

Abstract
INTRODUCTION There is increasing evidence that intermediate and long-term bowel dysfunction may occur as a consequence of radical surgery for rectal deep endometriosis (DE). Typical symptoms include constipation, feeling of incomplete evacuation, clustering of stools, and urgency. This is described in the colorectal surgical literature as low anterior resection syndrome (LARS). Within this, several studies suggested that differences regarding functional outcomes could be favorable to more conservative surgical approaches, that is, excision of endometriotic tissue with preservation of the luminal structure of the rectal wall when compared with classical segmental resection techniques for DE, especially when performed for low DE. MATERIAL AND METHODS A total of 211 patients undergoing rectal surgery for low DE (≤7 cm from the anal verge) in three different tertiary referral centers between October 2009 and December 2018 were retrospectively reviewed regarding major complications and LARS. From the 211 eligible patients, six women were excluded because of loss to follow-up. Finally, a total number of 205 patients were enrolled for the statistical analysis; 139 with nerve- and vessel-sparing segmental resection (NVSSR) and 66 operated for laparoscopic-transanal disk excision (LTADE) were included. Gastrointestinal functional outcomes of the two procedures were compared using the validated LARS questionnaire. The median follow-up time was 46 ± 11 months. As a secondary outcome, the surgical sequelae were examined. RESULTS We found no statistically significant difference between the incidence of LARS (31.7% and 37.9%, respectively) among patients operated by LTADE when compared with NVSSR (P = .4). The occurrence of LARS was positively associated with the use of protective ileostomy or colostomy (P = .02). A higher rate of severe complications was observed in women undergoing LTADE (19.7%) when compared with patients with NVSSR (9.0%, P = .029). CONCLUSIONS LARS is not more frequent after NVSSR when compared with a more conservative approach such as LTADE in patients undergoing rectal surgery for low DE. To confirm our findings prospective studies are required.

Abstract
Introduction: Bowel endometriosis is when endometrial-like tissue penetrates the bowel serosa, or it reaches the subserous neurovascular plexus. The effect of surgery for colorectal endometriosis on infertility and pregnancy is not fully proven. Aim: The aim of the present study was to analyse the pregnancy outcome and mode of delivery of patients who underwent 'nerve sparing' anterior resection of the colon. Method: Between 2009 and 2017, we operated 121 patients with bowel endometriosis, and built up a prospective database where we assessed their wish of pregnancy, the way of the conception, pathologies during pregnancy and mode of delivery. Statistical analysis: The relationship between endometriosis and pregnancy pathologies was tested by a χ2 probe and Fisher's exact test, additionally the odds ratio (OR) and 95% confidence interval (CI) were determined. For p<0.05, the result was considered significant. Results: Out of 121 bowel endometriosis patients, 48 (39.6%) women got pregnant, 37 (30.5%) of them with in vitro fertilisation. The control group was built from patients who underwent in vitro fertilisation because of andrological factors. We found that women with endometriosis have a significantly higher risk for praeeclampsia (p = 0.023) and placenta praevia (p = 0.045) during pregnancy. Conclusions: Our study is a unique description of pregnancy outcome and mode of delivery after surgery for bowel endometriosis, which, despite the small number of cases, has yielded similar results to the previous multicentric studies.

Abstract
STUDY QUESTION To what extent are pain symptoms, psychological variables (anxiety, depression and distress) and emotion regulation associated with women's health in endometriosis? SUMMARY ANSWER Physical pain symptoms and emotion regulation difficulties via psychological stress negatively affect the health-related quality of life (HRQoL) of women living with endometriosis. WHAT IS KNOWN ALREADY There are some missing links in the definitive treatment and recovery from endometriosis. Women with chronic pain report a decrease in HRQoL and an increase in the frequency of psychological problems, but little is known about the complex relationship between these variables in the context of endometriosis. STUDY DESIGN, SIZE, DURATION This cross-sectional study was conducted between October 2014 and October 2015 on 193 women living with endometriosis. PARTICIPANTS/MATERIALS, SETTING, METHODS The sample consisted of women with a medically confirmed diagnosis of endometriosis who received treatment at the participating clinic. All participants completed the Short Form Health Survey (SF-36), the Hospital Anxiety and Depression Scale, the Perceived Stress Scale and the Difficulties in Emotion Regulation Scale. Spearman's rank correlation was used to explore the associations between the measured variables, and structural equation modeling was used to test the proposed mediation models. MAIN RESULTS AND THE ROLE OF CHANCE The response rate was 46%. In this study, 54.79% of the participants presented with anxiety and 20.3% with depressive symptoms. Pain symptoms, psychological variables and difficulties in emotion regulation were negatively associated with HRQoL. Mediation models revealed that physical pain, psychological stress and difficulties in emotion regulation explained 55% of the variance in the overall HRQoL, 41% of the variation in physical and 55% of the variation in mental HRQoL. Accordingly, severe physical pain (β = -0.39, P < 0.001) was directly, and difficulties in emotion regulation (β = -0.38, P < 0.001) was indirectly related to deterioration in overall HRQoL. Physical pain had a higher direct standardized effect (β = -0.51, P < 0.001) on physical HRQoL, and had no significant direct effect on mental HRQoL. Furthermore, both physical pain (β = -0.07, P < 0.001) and difficulties in emotion regulation (β = -0.46, P < 0.001) had a significant indirect effect on mental HRQoL. LIMITATIONS, REASONS FOR CAUTION The data were heterogeneous with regard to the severity of endometriosis. The validity of this cross-sectional study is limited to correlations; therefore, further longitudinal studies using a more representative sample are needed to explore valid causal relationships. WIDER IMPLICATIONS OF THE FINDINGS The results of this study indicate that HRQoL can be improved through pain management and emotion regulation strategies. The authors believe that HRQoL would increase with concomitant application of physical treatment and psychological care. STUDY FUNDING/COMPETING INTEREST(S) There were no external funding sources for this study, and the authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER Not applicable.

Natural Orifice Specimen Extraction during Laparoscopic Bowel Resection for Colorectal Endometriosis: Technique and Outcome. J Minim Invasive Gynecol 2018; 25:1065-1074. [PMID: 29454144 DOI: 10.1016/j.jmig.2018.02.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 02/07/2018] [Accepted: 02/08/2018] [Indexed: 02/07/2023]
Abstract
STUDY OBJECTIVE To present a detailed description of a modified natural orifice specimen extraction (NOSE) colectomy technique. We also report the postoperative outcomes of our prospective case series when compared with conventional laparoscopic bowel resection in a relatively large series of patients. DESIGN Canadian Task Force classification II-1. SETTING A university tertiary referral center. PATIENTS The last 90 consecutive patients in our care with deep infiltrating endometriosis of the bowel are presented in this study. Patients were diagnosed at the 1st Department of Obstetrics and Gynecology, Semmelweis University, Budapest, Hungary. INTERVENTIONS We performed laparoscopic bowel resection using the transrectal NOSE technique and compared the results of the new operative method (n = 30) with traditional laparoscopic bowel resection (n = 60). MEASUREMENTS AND MAIN RESULTS The median duration of surgery was 121 minutes in the control group and 96 minutes in the NOSE group (p = .005). According to the Clavien-Dindo classification, we observed a severe, grade IIIb or higher, overall complication rate of 3.3% among all 90 patients. In the control group, anastomosis insufficiency occurred in 3.3% of patients (2/60 cases), and in 1 patient with anastomotic leakage a rectovaginal fistula was observed (1.7%). There was no significant difference in the rates of severe postoperative complications (p = .55). The length of hospital stay in the control group was a median of 7 days (range, 5-13 days), whereas in the NOSE group it was 6 days (range, 3-11 days) (p < .001). CONCLUSION According to our findings, the use of NOSE colectomy offers a shorter recovery time and can eventually lead to a shorter surgery duration compared with traditional laparoscopic bowel resection.

Abstract
OBJECTIVE To investigate the usefulness of soluble galectin-9 (Gal-9) in the noninvasive laboratory diagnosis of endometriosis and various gynecologic disorders. DESIGN Prospective case-control study. SETTING University medical centers. PATIENT(S) A total of 135 women of reproductive age were involved in the study, 77 endometriosis patients, 28 gynecologic controls, and 30 healthy women. INTERVENTION(S) Diagnostic laparoscopy and collection of tissue biopsies, peritoneal cells, and native peripheral blood from different case groups of gynecology patients and healthy women. MAIN OUTCOME MEASURE(S) The expression of mRNA and serum concentration of Gal-9. RESULT(S) Semiquantitative reverse transcription-polymerase chain reaction analysis and serum soluble Gal-9 ELISA were performed on three different cohorts of patients: those with endometriosis, those with benign gynecologic disorders, and healthy controls. Differences in the Gal-9 concentrations between the investigated groups and the stability of Gal-9 in the serum and diagnostic characteristics of Gal-9 ELISA were determined by statistical evaluation and receiver operating characteristic (ROC) curve analysis. Significantly elevated Gal-9 levels were found in both minimal-mild (I-II) and moderate-severe (III-IV) stages of endometriosis in comparison with healthy controls. At a cutoff of 132 pg/mL, ROC analysis revealed an excellent diagnostic value of Gal-9 ELISA in endometriosis (area under the curve = 0.973) with a sensitivity of 94% and specificity of 93.75%, indicating better diagnostic potential than that of other endometriosis biomarkers. Furthermore, various pelvic pain or infertility-associated benign gynecologic conditions were also associated with increased serum Gal-9 levels. CONCLUSION(S) Our results suggest that Gal-9 could be a promising noninvasive biomarker of endometriosis and a predictor of various infertility or pelvic pain-related gynecologic disorders.

Abstract
INTRODUCTION A number of the patients suffer from endometriosis increased in the past decades and the cases have became more serious. The most critical complication of bowel endometriosis is the large bowel obstruction. Up to recently, 16 similar case reports of large bowel endomteriosis causing obstruction, with detailed medical history have been published in the literature in English language. PATIENTS Since 2007 535 female have been treated in the 1st Gynaecological Department with endometriosis, out of them three patients from emergency surgery in the history because of large bowel obstruction. RESULTS Symptoms suggesting endometriosis or previous intervention due to endometriosis were detected in 59% (13/21) of the cases. Preoperative ultrasound, computertomography, magnetic resonance imaging did not give correct diagnosis. Colonoscopy was carried out before the primary operation in 61% (13/21) and after the surgery in 24% (5/21) of the cases, but none of them confirmed endometriosis. Although all the patients developed obstruction, only in 5% (1/19) of the patients was the mucosa infiltrated by the endometriosis. CONCLUSIONS In a young female patient, intestinal obstruction can be caused by bowel endometriosis. Identification of colonoscopic signs (rigidity, impression, kinking) of endometriosis may help to avoid unnecessary extension of intestinal resection. Gynaecologists should take part in the operations. Orv. Hetil., 2016, 157(49), 1960-1966.

Abstract
INTRODUCTION AND AIM In the treatment of colorectal endometriosis a multidisciplinary laparoscopic resection is suggested, for this reason the correct selection of bowel infiltration is essential before surgery. PATIENTS AND METHOD Between 2009 and 2015, 383 sigmoidoscopies were performed in patients with endometriosis. Where mucosal invasion was absent secondary signs (wall rigidity, impression, kinking, pain during the examination, suffusion) were analysed. In endoscopically confirmed cases multidisciplinary surgery was performed, the remaining patients were operated by a gynecologic team only. RESULTS Endometriosis was endoscopically confirmed in 224 patients (58.49%), 108 of them underwent multidisciplinary operation, the negative 135 cases received gynaecological surgery. Bowel endometriosis was confirmed in 103 out of 108 cases intraoperatively, while in 8 cases of the sigmoidoscopically negative patients bowel infiltration was diagnosed intraoperatively by the gynaecological team. Complete sigmoidoscopy was performed in 43.47% of the cases. Intraluminal endometriosis was found in 4.91%, secondary signs as rigidity in 38.39%, impression in 45.54%, kinking in 57.14%, pain (in cases of examination without narcosis) in 26.06% and suffusion in 3.82% of the cases was found during sigmoidoscopy. Sigmoidoscopic examination has a 92.8% specificity and 96.2% sensitivity in cases of bowel endometriosis. CONCLUSION Sigmoidoscopy performed by an experienced gastroenterologist is a highly sensitive examination for the diagnosis of bowel endometriosis. Orv. Hetil., 2017, 158(7), 264-269.

Abstract
INTRODUCTION The oncological treatment may damage ovarian function. To prevent this, it is possible to cryopreserve the ovarian tissue, and to keep the samples for long-term storage. The frozen-thawed tissue could be retransplanted after chemo- or radiotherapy. AIM The aim of our study was to examine the effect of cryopreservation on the viability of ovarian tissue. METHOD We analyzed the survival of frozen-thawed donated ovarian tissues. The quality of the follicles and hormone production in fresh and frozen-thawed samples were compared. RESULTS Histological analysis showed that the number of viable follicles was reduced by 23% in the frozen-thawed samples. However, viable follicles still presented in post thawing ovarian tissues. Maximal estradiol production in frozen-thawed tissues was 908 pg/ml and hormone production was similar to the control tissues. The maximal progesterone production was 1.95 ng/ml post thawing, but these values were lower than the progesterone production of fresh tissues. CONCLUSIONS The method of ovarian cryopreservation used in our laboratory was able preserve the viability of follicles in frozen-thawed ovarian tissues. Orv. Hetil., 2016, 157(49), 1947-1954.

Abstract
INTRODUCTION During laparoscopic partial colectomy the specimen can be extracted transrectally. This technique decreases the invasiveness of the surgery, because the abdominal wall incision is avoided. Premises of a new surgical technique are precise technical description as well as a favourable balance of advantages and disadvantages. In this paper the authors review the technique they apply and analyse their first results. PATIENTS AND METHOD 45 laparoscopic bowel resections were performed by a multidisciplinary team between 16th April 2014 and 1st November 2015. Indication of surgery was endometriosis, and the specimen was extracted transrectally in 11 patients. Having ligated both bowel ends proximal and distal to the section infiltrated with endometriosis, and the proximal bowel secured with a laparoscopic bulldog. Then the bowel was resected and the specimen was extracted in a camera bag transrectally. A purse-string suture was placed into the proximal bowel end, and the anvil of the circular stapler--which was introduced transrectally--was inserted into the bowel. After closing the rectal stump, the anastomosis was performed with a circular stapler. We used this technique when the upper third of the rectum or sigmoid colon was infiltrated with endometriosis. RESULTS The difference between the operation time of the two techniques (transabdominal vs. transrectal specimen extraction: 108 min vs. 118 min) was not significant. There was not difference in the WBC count between the first and second postoperative day, and there was not any anastomosis leakage detected either. CONCLUSION By using the above technique, postoperative infections could have been reduced to minimum. Transrectal specimen extraction did not increase postoperative complication The authors believe this is a safe way of specimen extraction after partial colectomy.

Abstract
OBJECTIVE To study single nucleotide polymorphisms (SNPs) involved in angiogenesis (VEGF, PLGF, VEGFR1, VEGFR2, HIF-1α) and plasma levels of the corresponding proteins (VEGF, PLGF, sVEGFR1, sVEGFR2) in women with and without endometriosis. DESIGN Allele frequencies of vascular endothelial growth factor (VEGF) pathway SNPs and plasma levels of the corresponding proteins were investigated in patients with endometriosis and in controls. SETTING University hospital. PATIENT(S) Samples of DNA from 1,931 Caucasian patients were included (1,109 patients with endometriosis and 822 controls). An additional study group included 973 DNA samples from volunteers, self-reported to be healthy without laparoscopic evaluation. INTERVENTION(S) Women who underwent a laparoscopy for subfertility and/or pain and healthy volunteers without laparoscopic evaluation. MAIN OUTCOME MEASURE(S) Functional SNPs of the VEGF, VEGFR1, VEGFR2, HIF-1α genes and Hap Map tagging SNPs of the PLGF gene were genotyped by using iPLEX technology on a Sequenom MassArray and TaqMan SNP Genotyping Assay. The VEGF levels were determined in ethylenediaminetetraacetic acid plasma samples by using Bio-Plex Protein Array System. PLGF, sVEGFR1, and sVEGFR2 levels were measured in ethylenediaminetetraacetic acid plasma samples by using ELISA Quantikine kits. RESULT(S) A significant association was found between the rs2268613 polymorphism in the PLGF gene and PLGF plasma levels. In all study subjects, women with the AA variant of the rs2268613 PLGF gene had significantly lower PLGF plasma levels (median [interquartile range] 9.36 [8.19-10.43] pg/mL) than those with the AG variant (12.1 [11.81-20.84] pg/mL; P(a)=.0085, P(b)=.04), both before and after multiple testing. Plasma levels of VEGF were elevated in endometriosis patients (especially in minimal-mild endometriosis during the menstrual cycle phase) compared with laparoscopic controls but had a moderate diagnostic performance (area under the curve, 0.73) in this discovery dataset. At a cut-off plasma level of VEGF >3.88 pg/mL, minimal-mild stages of endometriosis were diagnosed with a sensitivity of 74% and a specificity of 80% during the menstrual phase of cycle. The associations between the presence of endometriosis and SNPs in PLGF (rs2268614), HIF-1α (rs11549465), and VEGFR1 (rs9582036) genes lost statistical significance after multiple testing. CONCLUSION(S) Genetic variants in the PLGF rs2268613 gene may influence plasma levels of the corresponding protein. Plasma levels of VEGF were elevated in endometriosis patients compared with controls. The associations between the presence of endometriosis and SNPs in PLGF (rs2268614), HIF-1α (rs11549465), and VEGFR1 (rs9582036) genes lost statistical significance after multiple testing.

Abstract
INTRODUCTION Traditional surgeries performed in cases of deep infiltrating endometriosis lead to impaired quality of life. AIM To summarize the postoperative outcome and to compare the rate of postoperative complications after different therapeutic approaches applied in deep infiltrating endometriosis. METHOD The authors analized the articles published between March 31, 2004 and March 31, 2015, in the database http://www.pubmed.org using the following keywords: endometriosis, deep infiltrating, nerve sparing, surgery. RESULTS Non-nerve sparing surgery resulted in temporary urinary dysfunction in 19.1-38.5% of patients, while it occurred in 0.61-33.3% of patients after nerve-sparing surgery. Non-nerve sparing surgical technique resulted in an average of 121 days of need for self-catheretisation. When nerve-sparing surgeries were performed the duration of self-catheterisation varied between 7 to 39.8 days. After nerve sparing surgeries, permanent bladder dysfunction was not detected in any case. CONCLUSIONS Because of the successful treatment of the patients symptoms and the lower postoperative complication rate, nerve-sparing surgical technique leads to a significant improvement of the quality of life.

Abstract
INTRODUCTION The number of patients operated on with endometriosis increases, the urological organ and the bowels are involved in 10-40% of the cases in addition to the gynaecological organs. PATIENTS AND METHODS Sigmoideoscopy detected bowel endometriosis in 224 patients from 383 patients with endometriosis, and 127 patients were operated on from 14.07.2009 to 13.01.2014 at the 1st Gynaecological Department of Semmelweis University, Budapest, Hungary. All the operation was made by the same gynaecologist and surgeon team. RESULTS Segment resection of the bowel was performed in 120 patients, local resection in two patients and shaving in another two cases. The involved part of the bowels were the rectum at 46 patients, rectosigmoid in 68, sigmoid bowel in 30, coecum in 4, appendix in 2 and the small intestine in 2 patients. Bladder resection was carried out in 9 patients, ureter resection in two patients and ureterolysis in 26 cases were done due to infiltration of the urological organs. The laparoscopic operation needed to be converted on one single occasion due to bleeding from the epigastric artery, and a laparoscopic suture of the anastomosis was applied for bleeding in another patient. The specimen was extracted transvaginally in 16 patients and transanally in 13 patients. Anastomotic leakage was detected in two patients and rectovaginal fistula in four patients. All reoperations (creation and closing of the stoma) were done laparoscopically. CONCLUSIONS The treatment of the bowel endometriosis is suggested with segment resection by multidisciplinary team, where the invasivity can be decreased by transanal specimen extraction.

Abstract
INTRODUCTION Due to significant technical evolution complex surgeries can be performed laparoscopically nowadays. However, laparotomy is needed frequently for the extraction of the specimen, which decreases the advantages of laparoscopy. AIM The aim of the authors was to analyse and present their experience on the use of natural orifices and abdominal wall defects for extraction of the surgical specimen. METHOD From 2009 the authors used natural orifices (stomach, vagina, rectum) when viscerotomy was an obligate part of laparoscopic surgery and, in a special gastrointestinal laparoscopic operation, the gate of the inguinal hernia for specimen extraction. RESULTS In 3 patients benign lesions of the stomach were extracted using gastroscope. In 6 patients with bowel endometriosis, in whom the wall of the vagina was completely infiltrated, the resected bowel was extracted transvaginally, and in 5 patients transrectal extraction of the specimen was performed. In 2 patients the inguinal hernia was used for the surgical specimen extraction after laparoscopic sigmoid resection, and in one patient a single-port was inserted into the gate of the hernia during laparoscopic cholecystectomy. Complications occurred only after transvaginal specimen extraction (rectovaginal fistula in 2 patients). CONCLUSIONS Use of natural orifices and abdominal wall defects for surgical specimen extraction further decreases the invasiveness of laparoscopic surgery, if indications made appropriately.

Abstract
The authors report a case of a 27-year-old patient who had deeply infiltrating endometriosis involving the rectum, sigmoid colon and the rectovaginal septum, which was removed by laparoscopic surgery. During surgery the affected bowel segment, the deeply infiltrating nodule of the rectovaginal septum and the posterior vaginal wall were resected and the 12 cm long specimen was removed transvaginally. Postoperative bleeding was noted in the first postoperative day, which was treated laparoscopically, as well. This case history confirms data from the literature showing that the natural orifice specimen extraction procedure can widely be applied during operations for deeply infiltrating endometriosis and that laparoscopic anterior resection is a safe and feasible method for the treatment of colorectal deeply infiltratnig endometriosis. Moreover, perioperative complications can be treated by means of laparoscopic surgery.

Abstract
Epigenetic effects influence the function of genes regulating the main physiological mechanisms. Some of these environmental factors may reduce or inhibit the function of these genes. The environmental effects on gene function may result in a change of the DNA structure leading to non-heritable phenotype changes. Epigenetic factors play an important etiological role in the development of numerous diseases in obstetrics and gynecology. Uterine fibroids probably have a complex etiological background including epigenetic mechanisms. The multifactorial aetiology of endometriosis suggests key roles for immunological and hormonal factors in the development of the diseases. These mechanisms are influenced by epigenetic factors, which may serve as therapeutic targets in the future. The possible in utero origin of polycystic ovary syndrome determines the main directions of research concerning epigenetic factors in the etiological background, with the hope of eventual prevention and/or treatment in the preconceptional period as well as during pregnancy care.

Abstract
INTRODUCTION Deep infiltrating endometriosis is a particular form of endometriosis that penetrates the peritoneal surface or it reaches the subserosal neurovascular plexus. AIM The aim of the authors was to analyze the results of segmental colorectal resections performed for deep infiltrating endometriosis. METHOD Between 2009 and 2012, 50 patients underwent segmental rectum or/and sigmoid resection for endometriosis. RESULTS 21 patients had ultralow rectal resection and 29 patients had low colorectal anastomosis or anterior resection. Concomitant intervention in other organs was required in all cases, including gynecologic procedures (n = 50), additional gynecologic (n = 47), vesical (n = 9) and ureteral (n = 18) resections. The mean number of endometriosis lesions was 2.4±1.8 per patient. In all patients fertility was preserved. Severe surgical complications (Clavien-Dindo stage III or more severe) occurred in 3 patients (6%). CONCLUSIONS The results confirm that segmental bowel resection is an efficient and safe method for the treatment of deep infiltrating colorectal endometriosis. Orv. Hetil., 2014, 155(5), 182-186.

Abstract
Introduction: Endometriosis is one of the most common gynaecological diseases affecting 70 million women worldwide. Aim: The aims of this study were to determinate the diagnostic delay of endometriosis, to assess the effectiveness of surgical and combined therapy and to analyse the quality of life of women suffering from this disease. Method: Of the 240 patients with endometriosis enrolled in the study, 84 patients filled in a prospective as well as a retrospective questionnaire. Results: There was a 3.9 year delay from the onset of symptoms to the definitive diagnosis. Before therapy, 89% of the patients reported endometriosis related pain, while after therapy only 28% in the prospectively investigated months (p = 0.025). There was no significant difference between the outcome of surgical treatment alone and combined operative and medical therapy (p = 0.85). Reduced productivity at work was present in 47% of the patients and 40% of the patients reported impaired personal relationship, too. Endometriosis-associated symptoms generated 0.147 quality-adjusted life years per woman. Conclusions: This study is the first ever prospective survey to investigate the impact of endometriosis on the quality of life in Hungary. The results indicated a long diagnostic delay. Both surgical and combined therapies proved to be efficient. Endometriosis impaired health-related quality of life, but adequate therapy attenuated the severity of symptoms. Orv.

Abstract
STUDY QUESTION Is it possible to replicate the previously identified genetic association of four single-nucleotide polymorphisms (SNPs), rs12700667, rs7798431, rs1250248 and rs7521902, with endometriosis in a Caucasian population? SUMMARY ANSWER A borderline association was observed for rs1250248 and endometriosis (P = 0.049). However, we could not replicate the other previously identified endometriosis-associated SNPs (rs12700667, rs7798431 and rs7521902) in the same population. WHAT IS KNOWN ALREADY Endometriosis is considered a complex disease, influenced by several genetic and environmental factors, as well as interactions between them. Previous studies have found genetic associations with endometriosis for SNPs at the 7p15 and 2q35 loci in a Caucasian population. STUDY DESIGN, SIZE, DURATION Allele frequencies of SNPs were investigated in patients with endometriosis and controls. PARTICIPANTS/MATERIALS, SETTING, METHODS Blood samples and peritoneal biopsies were taken from a Caucasian female population consisting of 1129 patients with endometriosis and 831 controls. DNA was extracted for genotyping. The study was performed at a University hospital and research laboratories. MAIN RESULTS AND THE ROLE OF CHANCE A weak association with endometriosis (all stages) was observed for rs1250248 (P = 0.049). No significant associations were observed for the SNPs rs12700667, rs7798431 and rs7521902. A non-significant trend towards the association of rs1250248 with moderate/severe endometriosis was observed (odds ratio 1.18, 95% confidence interval 0.97-1.44). LIMITATIONS, REASONS FOR CAUTION The inability to confirm all previous findings may result from differences between populations and type II errors. WIDER IMPLICATIONS OF THE FINDINGS Our result demonstrates the difficulty of identifying common genetic variants in complex diseases. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by grants from the Karolinska Institutet and Stockholm City County/Karolinska Institutet (ALF), Stockholm, Sweden, Swedish Medical Research Council (K2007-54X-14212-06-3, K2010-54X-14212-09-3), Stockholm, Sweden, Leuven University Research Council (Onderzoeksraad KU Leuven), the Leuven University Hospitals Clinical Research Foundation (Klinisch onderzoeksfonds) and by the National Scientific Foundation (Fonds voor Wetenschappelijk Onderzoek, FWO).

Abstract
OBJECTIVE Epidemiological data indicate that endometriosis increases the risk of epithelial ovarian cancer (EOC), but the mechanism of cancer transition is unknown. Results from genome-wide association studies (GWAS) and transcriptome sequencing have demonstrated that genes located in the 1p36 region are important in both endometriosis and endometriosis-associated cancer development. Therefore, we tested the hypothesis that SNPs in two tumor-suppressor genes (CHD5 and ARID1A) in the 1p36 region are associated with endometriosis. METHODS Allele frequencies of SNPs were investigated in 1685 Caucasian women consisting of 947 women with endometriosis and 738 controls. Peripheral blood samples were retrieved, DNA extracted and allelic frequencies of SNPs in two tumor-suppressor genes (CHD5 and ARID1A) were analyzed using TaqMan Open Array technique. RESULTS Associations were observed for 3 SNPs in the CHD5 gene: rs1883603 (OR 1.31, 95% CI 1.00-1.71), rs9434741 (OR 1.41, 95% CI 1.16-1.71) and rs17436816 (OR 1.24, 95% CI 1.02-1.50). After correction for multiple comparisons, rs9434741 (CHD5) remained significantly associated with endometriosis (p<0.01). No associations were detected for ARID1A. CONCLUSIONS In this Caucasian population, endometriosis seems to be associated with the tumor-suppressor gene CHD5. Our findings support recent data, suggesting that the 1p36 region plays an important role in endometrios. To validate these data, replication in an independent population is warranted.

Abstract
OBJECTIVE To test the hypothesis that differential surface-enhanced laser desorption/ionization time-of-flight mass spectrometry protein or peptide expression in plasma can be used in infertile women with or without pelvic pain to predict the presence of laparoscopically and histologically confirmed endometriosis, especially in the subpopulation with a normal preoperative gynecologic ultrasound examination. METHODS Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry analysis was performed on 254 plasma samples obtained from 89 women without endometriosis and 165 women with endometriosis (histologically confirmed) undergoing laparoscopies for infertility with or without pelvic pain. Data were analyzed using least squares support vector machines and were divided randomly (100 times) into a training data set (70%) and a test data set (30%). RESULTS Minimal-to-mild endometriosis was best predicted (sensitivity 75%, 95% confidence interval [CI] 63-89; specificity 86%, 95% CI 71-94; positive predictive value 83.6%, negative predictive value 78.3%) using a model based on five peptide and protein peaks (range 4.898-14.698 m/z) in menstrual phase samples. Moderate-to-severe endometriosis was best predicted (sensitivity 98%, 95% CI 84-100; specificity 81%, 95% CI 67-92; positive predictive value 74.4%, negative predictive value 98.6%) using a model based on five other peptide and protein peaks (range 2.189-7.457 m/z) in luteal phase samples. The peak with the highest intensity (2.189 m/z) was identified as a fibrinogen β-chain peptide. Ultrasonography-negative endometriosis was best predicted (sensitivity 88%, 95% CI 73-100; specificity 84%, 95% CI 71-96) using a model based on five peptide peaks (range 2.058-42.065 m/z) in menstrual phase samples. CONCLUSION A noninvasive test using proteomic analysis of plasma samples obtained during the menstrual phase enabled the diagnosis of endometriosis undetectable by ultrasonography with high sensitivity and specificity. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND An early semi-invasive diagnosis of endometriosis has the potential to allow early treatment and minimize disease progression but no such test is available at present. Our aim was to perform a combined mRNA microarray and proteomic analysis on the same eutopic endometrium sample obtained from patients with and without endometriosis. METHODS mRNA and protein fractions were extracted from 49 endometrial biopsies obtained from women with laparoscopically proven presence (n= 31) or absence (n= 18) of endometriosis during the early luteal (n= 27) or menstrual phase (n= 22) and analyzed using microarray and proteomic surface enhanced laser desorption ionization-time of flight mass spectrometry, respectively. Proteomic data were analyzed using a least squares-support vector machines (LS-SVM) model built on 70% (training set) and 30% of the samples (test set). RESULTS mRNA analysis of eutopic endometrium did not show any differentially expressed genes in women with endometriosis when compared with controls, regardless of endometriosis stage or cycle phase. mRNA was differentially expressed (P< 0.05) in women with (925 genes) and without endometriosis (1087 genes) during the menstrual phase when compared with the early luteal phase. Proteomic analysis based on five peptide peaks [2072 mass/charge (m/z); 2973 m/z; 3623 m/z; 3680 m/z and 21133 m/z] using an LS-SVM model applied on the luteal phase endometrium training set allowed the diagnosis of endometriosis (sensitivity, 91; 95% confidence interval (CI): 74-98; specificity, 80; 95% CI: 66-97 and positive predictive value, 87.9%; negative predictive value, 84.8%) in the test set. CONCLUSION mRNA expression of eutopic endometrium was comparable in women with and without endometriosis but different in menstrual endometrium when compared with luteal endometrium in women with endometriosis. Proteomic analysis of luteal phase endometrium allowed the diagnosis of endometriosis with high sensitivity and specificity in training and test sets. A potential limitation of our study is the fact that our control group included women with a normal pelvis as well as women with concurrent pelvic disease (e.g. fibroids, benign ovarian cysts, hydrosalpinges), which may have contributed to the comparable mRNA expression profile in the eutopic endometrium of women with endometriosis and controls.

The burden of endometriosis: costs and quality of life of women with endometriosis and treated in referral centres. Hum Reprod 2012; 27:1292-9.

Abstract
BACKGROUND This study aimed to calculate costs and health-related quality of life of women with endometriosis-associated symptoms treated in referral centres. METHODS A prospective, multi-centre, questionnaire-based survey measured costs and quality of life in ambulatory care and in 12 tertiary care centres in 10 countries. The study enrolled women with a diagnosis of endometriosis and with at least one centre-specific contact related to endometriosis-associated symptoms in 2008. The main outcome measures were health care costs, costs of productivity loss, total costs and quality-adjusted life years. Predictors of costs were identified using regression analysis. RESULTS Data analysis of 909 women demonstrated that the average annual total cost per woman was €9579 (95% confidence interval €8559-€10 599). Costs of productivity loss of €6298 per woman were double the health care costs of €3113 per woman. Health care costs were mainly due to surgery (29%), monitoring tests (19%) and hospitalization (18%) and physician visits (16%). Endometriosis-associated symptoms generated 0.809 quality-adjusted life years per woman. Decreased quality of life was the most important predictor of direct health care and total costs. Costs were greater with increasing severity of endometriosis, presence of pelvic pain, presence of infertility and a higher number of years since diagnosis. CONCLUSIONS Our study invited women to report resource use based on endometriosis-associated symptoms only, rather than drawing on a control population of women without endometriosis. Our study showed that the economic burden associated with endometriosis treated in referral centres is high and is similar to other chronic diseases (diabetes, Crohn's disease, rheumatoid arthritis). It arises predominantly from productivity loss, and is predicted by decreased quality of life.

Abstract
BACKGROUND Endometriosis is a common benign gynaecological disease. Epidemiological studies have demonstrated associations between endometriosis and ovarian cancer. Recent genome-wide association studies of ovarian cancer have identified several single nucleotide polymorphisms (SNPs) in the Basonuclin 2 (BNC2) gene. In this study, we investigated these polymorphism in women with endometriosis. METHODS Six SNPs in and upstream of the BNC2 gene (rs3814113, rs4445329, rs10962656, rs12379183, rs10756819 and rs1339552) were investigated using TaqMan allelic discrimination analysis in a Caucasian population (cases: 798, controls: 351). Allelic frequencies were used as main outcome measure. RESULTS No associations were observed between the analysed SNPs and endometriosis. CONCLUSIONS Our results suggest that the analysed polymorphisms in the BNC2 gene are unlikely to contribute to the previously reported risk of ovarian cancer in women with endometriosis.

Abstract
Az endometriosis korszerű sebészi kezelésének célja a károsodott kismedencei anatómia helyreállításával az endometriosishoz társuló fájdalomtünetek csökkentése, illetve a teherbe esési esélyek javítása. Cikkünkben a különböző elhelyezkedésű kismedencei endometriosislaesiók eltávolításának műtéti lehetőségeit elemezzük. Az endometriosis sebészi kezelése döntően laparoszkópia útján valósul meg, míg a laparotomia alkalmazási köre egyre inkább beszűkült és csak speciális esetekre korlátozódik. A peritonealis endometriosis laesiói reszekció, elektrokoaguláció vagy lézervaporizáció segítségével kezelhetők, amelyek azonos mértékben csökkentik az endometriosishoz társuló fájdalomtüneteket, illetve javítják a teherbe esési esélyeket. Az endometrioma kezelésében hosszú éveken át kétféle műtéti megoldás terjedt el; a cisztatok eltávolítása az úgynevezett strippingtechnika segítségével, valamint a cisztatok megszüntetése az ablatiós műtéti technikával. Napjainkra egyértelműen bebizonyosodott, hogy a stripping előnyösebb az endometrioma ablatiójával szemben mind a fájdalomtünetek csökkenése, mind a reproduktív funkciók szempontjából. A mélyen infiltráló endometriosis kezelése jelenti a legnagyobb kihívást az endometriosis sebészetében. A mélyen infiltráló laesiók eltávolításában a lézertechnika alkalmazásának jut főszerep. A rectovaginalis septum endometriosisa esetén lézer segítségével a mélyen infiltráló laesio biztonsággal és maradéktalanul eltávolítható. Bélendometriosis esetén az érintett bélszakaszt szegmentális reszekcióval, discreszekcióval vagy az úgynevezett shavingtechnikával távolíthatjuk el. Leggyakrabban a szegmentális reszekciót alkalmazzuk, mivel egyedül ez esetben biztosítható a reszekciós szél biztos épsége. Az ureter endometriosisa esetén kisfokú érintettség mellett ureterolysis, míg obstruktív uropathia fennállásakor az ureter reszekciója javasolható. Az endometriosishoz társuló fájdalom hatékonyabb csökkentését célozza a praesacralis neurectomia és az uterusidegrost-ablatio. Ezen beavatkozások klinikai eredményessége azonban nem egyértelmű, az endometriosis kezelésében betöltött pontos szerepük tisztázása további vizsgálatokat igényel. Az endometriosis sebészetében a folyamatosan fejlődő műtéti technikák az endometriosislaesiók egyre teljesebb és hatékonyabb eltávolítását teszik lehetővé, amelynek köszönhetően egyre eredményesebben kezelhetők az endometriosishoz társuló klinikai tünetek és csökkenthető a betegség kiújulásának veszélye.
