Abstract
PURPOSE Patients often undergo repeat surgery for endometriosis, due to recurrent or residual disease. Previous surgery is often considered a risk factor for worse surgical outcome. However, data are scarce concerning the influence of subsequent endometriosis surgery. METHODS A retrospective study in a centre of expertise for endometriosis was conducted. All endometriosis subtypes and intra-operative steps were included. Detailed information regarding surgical history of patients was collected. Surgical time, intra-operative steps and major post-operative complications were obtained as outcome measures. RESULTS 595 patients were included, of which 45.9% had previous endometriosis surgery. 7.9% had major post-operative complications and 4.4% intra-operative complications. The patient journey showed a median of 3 years between previous endometriosis surgeries. Each previous therapeutic laparotomic surgery resulted on average in 13 additional minutes (p = 0.013) of surgical time. Additionally, it resulted in more frequent performance of adhesiolysis (OR 2.96, p < 0.001) and in a higher risk for intra-operative complications (OR 1.81, p = 0.045), however no higher risk for major post-operative complications (OR 1.29, p = 0.418). Previous therapeutic laparoscopic endometriosis surgery, laparotomic and laparoscopic non-endometriosis surgery showed no association with surgical outcomes. Regardless of previous surgery, disc and segmental bowel resection showed a higher risk for major post-operative complications (OR 3.64, p = 0.017 respectively OR 3.50, p < 0.001). CONCLUSION Previous therapeutic laparotomic endometriosis surgery shows an association with longer surgical time, the need to perform adhesiolysis, and more intra-operative complications in the subsequent surgery for endometriosis. However, in a centre of expertise with experienced surgeons, no increased risk of major post-operative complications was observed.

Abstract
STUDY QUESTION What is the additional value of the comprehensive complication index (CCI) and ClassIntra system (classification for intraoperative adverse events (ioAEs)) in adverse event (AE) reporting in (deep) endometriosis (DE) surgery compared to only using the Clavien-Dindo (CD) system? SUMMARY ANSWER The CCI and ClassIntra are useful additional tools alongside the CD system for a complete and uniform overview of the total AE burden in patients with extensive surgery (such as DE), and with this uniform data registration, it is possible to provide greater insight into the quality of care. WHAT IS KNOWN ALREADY Uniform comparison of AEs reported in the literature is hampered by scattered registration. In endometriosis surgery, the usage of the CD complication system and the CCI is internationally recommended; however, the CCI is not routinely adapted in endometriosis care and research. Furthermore, a recommendation for ioAEs registration in endometriosis surgery is lacking, although this is vital information in surgical quality assessments. STUDY DESIGN SIZE DURATION A prospective mono-center study was conducted with 870 surgical DE cases from a non-university DE expertise center between February 2019 and December 2021. PARTICIPANTS/MATERIALS SETTING METHODS Endometriosis cases were collected with the EQUSUM system, a publicly available web-based application for registration of surgical procedures for endometriosis. Postoperative adverse events (poAEs) were classified with the CD complication system and CCI. Differences in reporting and classifying AEs between the CCI and the CD were assessed. ioAEs were assessed with the ClassIntra. The primary outcome measure was to assess the additional value toward the CD classification with the introduction of the CCI and ClassIntra. In addition, we report a benchmark for the CCI in DE surgery. MAIN RESULTS AND THE ROLE OF CHANCE A total of 870 DE procedures were registered, of which 145 procedures with one or more poAEs, resulting in a poAE rate of 16.7% (145/870), of which in 36 cases (4.1%), the poAE was classified as severe (≥Grade 3b). The median CCI (interquartile range) of patients with poAEs was 20.9 (20.9-31.7) and 33.7 (33.7-39.7) in the group of patients with severe poAEs. In 20 patients (13.8%), the CCI was higher than the CD because of multiple poAEs. There were 11 ioAEs reported (11/870, 1.3%) in all procedures, mostly minor and directly repaired serosa injuries. LIMITATIONS REASONS FOR CAUTION This study was conducted at a single center; thus, trends in AE rates and type of AEs could differ from other centers. Furthermore, no conclusion could be drawn on ioAEs in relation to the postoperative course because the power of this database is not robust enough for that purpose. WIDER IMPLICATIONS OF THE FINDINGS From our data, we would advise to use the Clavien-Dindo classification system together with the CCI and ClassIntra for a complete overview of AE registration. The CCI appeared to provide a more complete overview of the total burden of poAEs compared to only reporting the most severe poAEs (as with CD). If the use of the CD, CCI, and ClassIntra is widely adapted, uniform data comparison will be possible at (inter)national level, providing better insight into the quality of care. Our data could be used as a first benchmark for other DE centers to optimize information provision in the shared decision-making process.

Abstract
Background: Deep Endometriosis (DE) classification studies with Enzian never compared solitary (A, B, C, F), and combinations of anatomical locations (A&B, A&C, B&C, A&B&C), in correlation to pain. Therefore, the results of these studies are challenging to translate to the clinical situation.
Objectives: We studied pain symptoms and their correlation with the solitary and combinations of anatomical locations of deep endometriosis lesion(s) classified by the Enzian score.
Materials and Methods: A prospective multi-centre study was conducted with data from university and non-university hospitals. A total of 419 surgical DE cases were collected with the web-based application called EQUSUM (www.equsum.org).
Main outcome measures: Preoperative reported numeric rating scale (NRS) were collected along with the Enzian classification. Baseline characteristics, pain scores, surgical procedure and extent of the disease were also collected.
Results: In general, more extensive involvement of DE does not lead to an increase in the numerical rating scale for pain measures. However, dysuria and bladder involvement do show a clear correlation AUC 0.62 (SE 0.04, CI 0.54-0.71, p< 0.01). Regarding the predictive value of dyschezia, we found a weak, but significant correlation with ureteric involvement; AUC 0.60 (SE 0.04, CI 0.53-0.67, p< 0.01).
Conclusions:TPain symptoms poorly correlate with anatomical locations of deep endometriosis in almost all pain scores, with the exception of bladder involvement and dysuria which did show a correlation. Also, dyschezia seems to have predictive value for DE ureteric involvement and therefore MRI or ultrasound imaging (ureter and kidney) could be recommended in the preoperative workup of these patients.
What’s new? Dyschezia might have a predictive value in detecting ureteric involvement.

Abstract
Abstract
Study question
Can cryopreserved-thawed human ovarian cortex be cultured in vitro to produce growing follicles as efficiently as from fresh samples?
Summary answer
In contrast to fresh samples, cryopreserved-thawed ovarian cortex did not develop morphologically normal growing follicles, even when adding follicular growth stimulators.
What is known already
A multistep culture system has been shown to produce mature oocytes from immature follicles present in the human cortex, without the addition of follicular growth stimulators. However, these promising results were achieved using fresh human ovarian cortex tissue donated from cisgender women, which is not available for the purpose of fertility preservation. It remains unclear whether this multistep culture system can be used to mature follicles from cryopreserved-thawed human ovarian cortex. In addition, the applicability of the culture system to mature follicles in vitro has not been investigated using ovarian tissue from transmasculine people.
Study design, size, duration
Fresh and cryopreserved ovarian cortex tissue isolated from the same transmasculine people were cultured during 8 days (first step of the culture system) with or without the addition of a PI3K/Akt promotor, Sphingosine-1-Phosphate (S1P). The ovarian cortex fragments were collected a day 0 and day 8 for downstream morphological and quantitative analysis of the follicular population. This study also included data of in vitro culture of cryopreserved samples from oncological cisgender women.
Participants/materials, setting, methods
Ovarian cortex tissue was collected from six testosterone user transmasculine people (25,8 ± 4,9 years) and three oncological cisgender women (24,0 ± 6,0 years). Fresh cortex was either directly cultured or previously cryopreserved. All ovarian fragments were cultured in the same conditions for 8 days. After the culture period, follicular population was quantified on histological sections (haematoxylin-eosin) and compared to samples of day 0. Follicular cell types, cell proliferation and apoptosis were assessed by immunofluorescence.
Main results and the role of chance
Fresh ovarian cortex tissue isolated from transmasculine people showed morphologically normal primary follicles (PFs) and secondary follicles (SFs) after 8 days of culture and no antral follicles were observed. Moreover, the addition of the follicular growth stimulator, S1P, to the culture medium significantly increased the number of growing follicles (PFs, P < 0.05; SFs, P < 0.01). The addition of S1P stimulated the emergence of SFs that showed expression of anti-mullerian hormone (AMH), contained proliferative (PCNA+) granulosa cells and showed low levels of apoptotic cells (TUNEL assay). Structurally, these in vitro grown SFs showed an intact basement membrane assessed by the expression of collagen IV. By contrast, using the same culture protocol but starting from cryopreserved-thawed cortex tissue from the same patients resulted in a very low number of viable growing follicles (PFs and SFs) even in the presence of S1P. Lastly, when using the same culture protocol on cryopreserved-thawed samples from oncological cisgender women, we observed a low efficiency of follicular growth, comparable to that observed in cryopreserved ovarian tissue from (age-matched) transmasculine people.
Limitations, reasons for caution
Limitations of this study are: small sample size and lack of fresh cortex tissue from oncological cisgender women. Due to the high variability of follicular density among patients, the use of a larger number of samples is recommended.
Wider implications of the findings
Optimization of culture systems to grow and mature follicles in the ovarian cortex of cryopreserved samples (both from cis and trans persons) is urgently needed. Current culture protocols can be applied to fresh samples, but further characterization is needed to consider this as an alternative in fertility preservation treatment.

Abstract
Current strategies for fertility preservation include the cryopreservation of embryos, mature oocytes or ovarian cortical tissue for autologous transplantation. However, not all patients that could benefit from fertility preservation can use the currently available technology. In this regard, obtaining functional mature oocytes from ovarian cortical tissue in vitro would represent a major breakthrough in fertility preservation as well as in human medically assisted reproduction. In this study, we have used a microfluidics platform to culture cryopreserved-thawed human cortical tissue for a period of 8 days and evaluated the effect of two different flow rates in follicular activation and growth. The results showed that this dynamic system supported follicular development up to the secondary stage within 8 days, albeit with low efficiency. Surprisingly, the stromal cells in the ovarian cortical tissue were highly sensitive to flow and showed high levels of apoptosis when cultured under high flow rate. Moreover, after 8 days in culture, the stromal compartment showed increase levels of collagen deposition, in particular in static culture. Although microfluidics dynamic platforms have great potential to simulate tissue-level physiology, this system still needs optimization to meet the requirements for an efficient in vitro early follicular growth.

Abstract
Objective To study the preferences of women with deep endometriosis (DE) with bowel involvement when they have to choose between conservative (medication) or surgical treatment. Design Labelled discrete choice experiment (DCE). Setting Dutch academic and non‐academic hospitals and online recruitment. Population or Sample A total of 169 women diagnosed with DE of the bowel. Methods Baseline characteristics and the fear of surgery were collected. Women were asked to rank attributes and choose between hypothetical conservative or surgical treatment in different choice sets (scenarios). Each choice set offered different levels of all treatment attributes. Data were analysed by using multinomial logistic regression. Main Outcome Measures The following attributes – effect on/risk of pain, fatigue, pregnancy, endometriosis lesions, mood swings, osteoporosis, temporary stoma and permanent intestinal symptoms – were used in this DCE. Results In the ranking, osteoporosis was ranked with low importance, whereas in the DCE, a lower chance of osteoporosis was one of the most important drivers when choosing a conservative treatment. Women with previous surgery showed less fear of surgery compared with women without surgery. Low anterior resection syndrome was almost equally important for patients as the chance of pain reduction. Pain reduction had higher importance than improving fertility chances, even in women with desire for a future child. Conclusions The risk of developing low anterior resection syndrome as a result of treatment is almost equally important as the reduction of pain symptoms. Women with previous surgery experience less fear of surgery compared with women without a surgical history. Tweetable Abstract First discrete choice experiment in patients with deep endometriosis.

Abstract
Background: Subfertility occurs in 30-40% of endometriosis patients. Regarding the fertilisation rate with in vitro fertilisation (IVF) and endometriosis, conflicting data has been published. This study aimed to compare endometriosis patients to non-endometriosis cycles assessing fertilisation rates in IVF. Methods: A population-based cohort study was conducted at the Leiden University Medical Center. IVF cycles of endometriosis patients and controls (unexplained infertility and tubal pathology) were analysed. The main outcome measurement was fertilisation rate. Results: 503 IVF cycles in total, 191 in the endometriosis group and 312 in the control. The mean fertilisation rate after IVF did not differ between both groups, 64.1%±25.5 versus 63.9%±24.8 (p=0.95) respectively, independent of age and r-ASRM classification. The median number of retrieved oocytes was lower in the endometriosis group (7.0 versus 8.0 respectively, p=0.19) and showed a significant difference when corrected for age (p=0.02). When divided into age groups, the statistical effect was only seen in the group of ≤ 35 years (p=0.04). In the age group ≤35, the endometriosis group also showed significantly more surgery on the internal reproductive organs compared to the control group (p<0.001). All other outcomes did not show significant differences. Conclusion: Similar fertilisation rates were found in endometriosis IVF cycles compared to controls. The oocyte retrieval was lower in the endometriosis group, however this effect was only significant in the age group ≤ 35 years. All other secondary outcomes did not show significant differences. In general, endometriosis patients with an IVF indication can be counselled positively regarding the chances of becoming pregnant, and do not need a different IVF approach.

Abstract
STUDY QUESTION Is electronic digital classification/staging of endometriosis by the EQUSUM application more accurate in calculating the scores/stages and is it easier to use compared to non-digital classification? SUMMARY ANSWER We developed the first digital visual classification system in endometriosis (EQUSUM). This merges the three currently most frequently used separate endometriosis classification/scoring systems (i.e. revised American Society for Reproductive Medicine (rASRM), Enzian and Endometriosis Fertility Index (EFI)) to allow uniform and adequate classification and registration, which is easy to use. The EQUSUM showed significant improvement in correctly classifying/scoring endometriosis and is more user-friendly compared to non-digital classification. WHAT IS KNOWN ALREADY Endometriosis classification is complex and until better classification systems are developed and validated, ideally all women with endometriosis undergoing surgery should have a correct rASRM score and stage, while women with deep endometriosis (DE) should have an Enzian classification and if there is a fertility wish, the EFI score should be calculated. STUDY DESIGN SIZE DURATION A prospective endometriosis classification proof of concept study under experts in deep endometriosis was conducted. A comparison was made between currently used non-digital classification formats for endometriosis versus a newly developed digital classification application (EQUSUM). PARTICIPANTS/MATERIALS SETTING METHODS A hypothetical operative endometriosis case was created and summarized in both non-digital and digital form. During European endometriosis expert meetings, 45 DE experts were randomly assigned to the classic group versus the digital group to provide a proper classification of this DE case. Each expert was asked to provide the rASRM score and stage, Enzian and EFI score. Twenty classic forms and 20 digital forms were analysed. Questions about the user-friendliness (system usability scale (SUS) and subjective mental effort questionnaire (SMEQ)) of both systems were collected. MAIN RESULTS AND THE ROLE OF CHANCE The rASRM stage was scored completely correctly by 10% of the experts in the classic group compared to 75% in the EQUSUM group (P < 0. 01). The rASRM numerical score was calculated correctly by none of the experts in the classic group compared with 70% in the EQUSUM group (P < 0.01). The Enzian score was correct in 60% of the classic group compared to 90% in the EQUSUM group (P = 0.03). EFI scores were calculated correctly in 25% of the classic group versus 85% in the EQUSUM group (P < 0.01). Finally, the usability measured with the SUS was significantly better in the EQUSUM group compared to the classic group: 80.8 ± 11.4 and 61.3 ± 20.5 (P < 0.01). Also the mental effort measured with the SMEQ was significant lower in the EQUSUM group compared to the classic group: 52.1 ± 18.7 and 71.0 ± 29.1 (P = 0.04). Future research should further develop and confirm these initial findings by conducting similar studies with larger study groups, to limit the possible role of chance. LIMITATIONS REASONS FOR CAUTION These first results are promising, however it is important to note that this is a preliminary result of experts in DE and needs further testing in daily practice with different types (complex and easy) of endometriosis cases and less experienced gynaecologists in endometriosis surgery. WIDER IMPLICATIONS OF THE FINDINGS This is the first time that the rASRM, Enzian and EFI are combined in one web-based application to simplify correct and automatic endometriosis classification/scoring and surgical registration through infographics. Collection of standardized data with the EQUSUM could improve endometriosis reporting and increase the uniformity of scientific output. However, this requires a broad implementation. STUDY FUNDING/COMPETING INTERESTS To launch the EQUSUM application, a one-time financial support was provided by Medtronic to cover the implementation cost. No competing interests were declared.

Abstract
OBJECTIVE To study the experiences, considerations, and motivations of patients with endometriosis in the decision-making process for deep endometriosis (DE) treatment options. DESIGN Qualitative study using semi-structured in-depth focus group methodology. SETTING University medical center. PATIENT(S) A total of 19 Dutch women diagnosed with DE between 27 and 47 years of age. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) Focus group topics were disease impact and motives for treatment, expectations of the treatment process, and important factors in the decision process. RESULT(S) Women reported that pain, fertility, and strong fear of complications are important decisive factors in the treatment process. The goal of conceiving a child is considered important, however, sometimes doctors emphasize this topic too much. It emerged that complication counseling is frequently about surgical complications, whereas side effects of hormonal treatments are neglected. Shared decision making and information about treatment options, complications, and side effects are not always optimal, making it difficult to make a well-considered choice. Despite negative experiences encountered after surgery, the positive effect of surgery ensures that most women do not regret their choice. CONCLUSION(S) In the treatment decision process for patients with DE, pain is almost always the most important decisive factor. The wish to conceive and strong fear of complications can change this choice. Doctors should understand the importance of fertility for the majority of women, but, also, if this is not considered paramount, respect that view. To improve shared decision making, exploration of treatment goals, training of healthcare providers, and better patient information provision are desirable.
