Lesion size and location in deep infiltrating bowel endometriosis: Correlation with gastrointestinal dysfunction and pain.

INTRODUCTION: Presence of deep infiltrating bowel endometriosis (DE) is associated with occurrence of dyschezia and gastrointestinal symptoms. The degree of the disease, the lesion length, and the location, that is, lesion-to-anal-verge distance (LAVD) of DE, as well as the severity of the symptoms appear to be correlated. Nevertheless, it is not yet known to what extent the size and LAVD of bowel DE influence the severity of gastrointestinal symptoms. The present study aims to evaluate a possible correlation of lesion location (LAVD) and size (according to the #Enzian classification) with preoperative symptoms. MATERIAL AND METHODS: In this prospective study, premenopausal patients with histologically confirmed DE undergoing modified limited nerve-vessel sparing rectal segmental bowel resection or full-thickness discoid resection were evaluated. Extent of endometriosis was defined according to the #Enzian classification during surgery. The primary outcome measure was the correlation between lesion size and location with the GI function impairment reflected by presurgical lower anterior resection syndrome (LARS) scores; the secondary outcome was differences in presurgical numeric rating scale pain scores of dyschezia, dyspareunia, and dysmenorrhea as well as the impact of concomitant DE of other locations on symptom intensity. RESULTS: Of 162 consecutive patients, 151 were included in the final analysis. No significant correlation was observed between lesion size (#Enzian compartments C1/C2/C3) or LAVD and GI dysfunction reflected by LARS-like symptoms (p = 0.314 and p = 0.185, respectively) or pain symptoms (dyschezia, p = 0.440; dyspareunia, p = 0.136; and dysmenorrhea p = 0.221). Furthermore, no significant correlation was observed between lesion size and GI dysfunction when merging two severity grades (#Enzian compartments C1 plus C2 vs. C3; p = 0.611). In addition, LAVD did not affect the degree of dyschezia (p = 0.892), dyspareunia (p = 0.395), or dysmenorrhea (p = 0.705). Finally, the presence of concomitant DE lesions infiltrating the vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) did not alter the severity of preoperative dyschezia (p = 0.493) or dysmenorrhea (p = 0.128) but showed a trend toward affecting gastrointestinal function (p = 0.078) and was significantly associated with dyspareunia (p = 0.035). CONCLUSIONS: In present study, we could not find a correlation between colorectal DE lesion size and location (LAVD) and gastrointestinal function impairment or intensity of dyschezia and dysmenorrhea. Additional involvement of vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) exerts a significant impact on the degree of dyspareunia in women with colorectal DE.

IVF with reception of oocytes from partner in lesbian couples: a systematic review and SWOT analysis.

The growing utilization of assisted reproductive technology (ART) by the LGBTQ+ community, especially among lesbian couples, challenges societal norms and promotes inclusivity. The reception of oocytes from partner (ROPA) technique enables both female partners to have a biological connection to their child. A systematic review was conducted of the literature on ROPA IVF to provide the latest data and a SWOT analysis was subsequently performed to understand the strengths, weaknesses, opportunities and threats associated with ROPA IVF. Publications from 2000 to 2023 with relevant keywords were reviewed and 16 records were included. Five studies provided clinical information on couples who used ROPA IVF. ROPA IVF provides a unique opportunity for a biological connection between the child and both female partners and addresses concerns related to oocyte donation and anonymity. Weaknesses include limited cost-effectiveness data and unresolved practical implications. Opportunities lie in involving both partners in parenthood, advancing ART success rates and mitigating risks. Threats encompass increased pregnancy complications, ethical concerns, insufficient safety data, legal or cultural barriers, and emotional stress. In conclusion, ROPA IVF offers a promising solution for lesbian couples seeking to create a family in which both partners want to establish a biological connection with their child.

Analyses of All Small Molecule-Based Pentacene/C60 Organic Photodiodes Using Vacuum Evaporation Method.

The vacuum process using small molecule-based organic materials to make organic photodiodes (OPDIs) will provide many promising features, such as well-defined molecular structure, large scalability, process repeatability, and good compatibility for CMOS integration, compared to the widely used Solution process. We present the performance of planar heterojunction OPDIs based on pentacene as the electron donor and C60 as the electron acceptor. In these devices, MoO3 and BCP interfacial layers were interlaced between the electrodes and the active layer as the electron- and hole-blocking layer, respectively. Typically, BCP played a good role in suppressing the dark current by two orders higher than that without that layer. These devices showed a significant dependence of the performance on the thickness of the pentacene. In particular, with the pentacene thickness of 25 nm, an external quantum efficiency at the 360 nm wavelength according to the peak absorption of C60 was enhanced by 1.5 times due to a cavity effect, compared to that of the non-cavity device. This work shows the importance of a vacuum processing approach based on small molecules for OPDIs, and the possibility of improving the performance via the optimization of the device architecture.

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.

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.

Should we stop screening for chronic endometritis?

Chronic endometritis is a poorly understood infectious or inflammatory process, potentially disrupting the correct implantation of a human embryo (Puente et al., 2020). The exact prevalence is a subject of discussion and ranges across the available literature from 2% to almost 60%, with a higher suspicion of the condition being present in women with recurrent early pregnancy loss and recurrent implantation failure (Puente et al., 2020). The impact of chronic endometritis on reproductive outcomes following IVF remains questionable given the lack of proper data convincingly showing an improvement after diagnosis and treatment. This article aims to provide the reader with a critical appraisal of current diagnostic methods, treatments and patient populations to be tested for chronic endometritis.

Differences in intensity and quality of bowel symptoms in patients with colorectal endometriosis : An observational cross-sectional study.

BACKGROUND: Patients suffering from colorectal deep endometriosis (DE) experience gastrointestinal symptoms with almost the same frequency as gynecological pain symptoms. Preoperatively existing gastrointestinal symptoms may translate into pathological gastrointestinal quality of life index (GIQLI) and low anterior resection syndrome scores (LARS). This prospective questionnaire-based case control study aims to assess the prevalence of gastrointestinal complaints reflected by changes in LARS and GIQLI scores in patients with colorectal deep endometriosis prior to surgical treatment and compare those to a healthy control group. METHODS: The study was conducted at the Hospital St. John of God in Vienna and included a total of 97 patients with histologically confirmed colorectal DE with radical surgical treatment and 96 women in whom DE was excluded via transvaginal sonography (TVS) or visually. Gastrointestinal symptoms reflected by LARS and GIQLI scores were evaluated presurgically and in controls. RESULTS: A total of 193 premenopausal patients were included in this study. A mean GIQLI of 90.7 ± 22.0 and 129.4 ± 11.1 was observed among patients and controls, respectively, showing a significantly higher morbidity concerning gastrointestinal symptoms and decreased quality of life (QoL) compared to healthy controls (p < 0.001). The LARS score results demonstrated that 18.6% of the patients with bowel DE presented with a major LARS and 27.8% with a minor LARS presurgically compared to 2.1% and 9.4% of control patients, respectively (p < 0.001). CONCLUSION: Patients with colorectal DE experience a quality of gastrointestinal symptoms translating into a decreased QoL and pathological GIQLI and LARS scores already presurgically. As a consequence, these instruments should be interpreted with caution.

Long-term surgical outcomes of nerve-sparing discoid and segmental resection for deep endometriosis.

INTRODUCTION: The aim of this study was to investigate long-term outcomes in terms of pain, quality of life (QoL), and gastrointestinal symptoms in women following colorectal surgery for deep endometriosis. MATERIAL AND METHODS: In this historical cohort, women who underwent surgical treatment for deep endometriosis by either nerve-sparing full-thickness discoid resection (DR) or colorectal segmental resection (SR) between March 2011 and August 2016 were re-evaluated through telephone interviews about their long-term pain symptoms, subjective overall QoL as rated using a score from 0 (worst) to 10 (optimal), and gastrointestinal outcomes reflected by lower anterior resection syndrome (LARS) following a first postsurgical evaluation (visit 1) published previously and a long-term follow-up evaluation (visit 2). RESULTS: The median long-term follow-up time was 35.4 months at visit 1 and 86 months at visit 2. Of 134 patients, 77 were eligible for final analysis and 57 were lost to follow-up. Compared with presurgical values, QoL scores were significantly increased at both postsurgical evaluation visits in both the SR cohort (scores of 3, 8.5, and 10 at the presurgical visit, visit 1, and visit 2, respectively; p < 0.001) and the DR cohort (scores of 3, 9, and 10, respectively; p < 0.001). Pain scores for dysmenorrhea (SR group scores of 8, 2, and 2, respectively; p < 0.001; DR group scores of 9, 2, and 1, respectively; p < 0.001), dyspareunia (SR group scores of 4, 0, and 0, respectively; p < 0.001; DR group scores of 5, 0, and 1, respectively; p = 0.003), and dyschezia (SR group scores of 8, 2, and 2, respectively; p < 0.001; DR group scores of 9, 2, and 1, respectively; p < 0.001) significantly decreased after surgery and remained stable in both cohorts over the follow-up period. Minor and major LARS, reflecting gastrointestinal function, was observed in 6.5% and 8.1% of the SR group and in 13.3% and 6.7% of the DR group, respectively, at visit 1 and in 3.2% and 3.2% of the SR group and 0% and 0% of the DR group, respectively, at visit 2, without significant differences between the SR and DR groups. CONCLUSIONS: Colorectal surgery for deep endometriosis, either by DR or SR, provides stable and long-term pain relief with low rates of permanent gastrointestinal function impairment.

Rates of severe complications in patients undergoing colorectal surgery for deep endometriosis-a retrospective multicenter observational study.

INTRODUCTION: Surgical experience and hospital procedure volumes have been associated with the risk of severe complications in expert centers for endometriosis in France. However, little is known about other certified units in Central European countries. MATERIAL AND METHODS: This retrospective observational study included 937 women who underwent surgery for colorectal endometriosis between January 2018 and January 2020 in 19 participating expert centers for endometriosis. All women underwent complete excision of colorectal endometriosis by rectal shaving, discoid or segmental resection. Postoperative severe complications were defined as grades III-IV of the Clavien-Dindo classification system including anastomotic leakage, fistula, pelvic abscess and hematoma. Surgical outcomes of centers performing less than 40 (group 1), 40-59 (group 2) and ≥60 procedures (group 3) over a period of 2 years were compared. RESULTS: The overall complication rate of grade III and IV complications was 5.1% (48/937), with rates of anastomotic leakage, fistula formation, abscess and hemorrhage in segmental resection, discoid resection and rectal shaving, respectively, as follows: anastomotic leakage 3.6% (14/387), 1.4% (3/222), 0.6% (2/328); fistula formation 1.6% (6/387), 0.5% (1/222), 0.9%; (3/328); abscess 0.5% (2/387), 0% (0/222) and 0.6% (2/328); hemorrhage 2.1% (8/387), 0.9% (2/222) and 1.5% (5/328). Higher overall complication rates were observed for segmental resection (30/387, 7.8%) than for discoid (6/222, 2.7%, P = 0.015) or shaving procedures (12/328, 3.7%, P = 0.089). No significant correlation was observed between the number of procedures performed and overall complication rates (rSpearman  = -0.115; P = 0.639) with a high variability of complications in low-volume centers (group 1). However, an intergroup comparison revealed a significantly lower overall severe complication rate in group 3 than in group 2 (2.9% vs 6.9%; P = 0.017) without significant differences between other groups. CONCLUSIONS: A high variability in complication rates does exist in centers with a low volume of activity. Major complications may decrease with an increase in the volume of activity but this effect cannot be generally applied to all institutions and settings.

Different segmental resection techniques and postoperative complications in patients with colorectal endometriosis: A systematic review.

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.

Laparoscopic vaginal bead pull-through vaginoplasty technique using dental prosthesis material.

OBJECTIVE: Many reconstructive surgical procedures have been described for vaginal agenesis. Almost all are surgically challenging, multistage, time-consuming or leave permanent scars on the abdomen or skin removal areas. The aim of this study was to introduce a simple and cheaper approach for laparoscopic vaginal bead-pull through. MATERIALS AND METHODS: In this retrospective study, we report a total of six patients with congenital absence of vagina [Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome] who were treated with a laparoscopic vaginal bead pull-through technique between 2018 till 2019 with a dental prosthesis material. RESULTS: Six patients with MRKH syndrome were treated with a laparoscopic vaginal bead pull-through technique. None of the women had any previous treatment. The mean age at the time of surgery was 18.7±3.1 years and mean body mass index was 25 (range, 19-38) kg/m2. None of the patients had any additional malformations. In all patients, normal external genitalia and complete vaginal agenesis were observed during examination. The mean duration of surgery was 72 (range, 55-95) minutes. All patients were discharged on the 3rd postoperative day. No intraoperative complications were encountered. All patients had their urinary catheters removed within 12 hours after surgery. The mean vaginal length at discharge was 10 (range, 8-13) cm and all patients had adequate vaginal diameter, allowing introduction of three fingers easily. At the 12th postoperative month, the mean vaginal length was 9.2±1.6 cm. All patients had complete epithelization. All the women were sexually active one year after surgery. CONCLUSION: The laparoscopic vaginal bead pull-through technique using dental prosthesis material can provide satisfactory results with shorter surgical time and lower cost.

Ultrasound predictors of candidates for segmental resection in pregnants with placenta accreta.

Objective: We aimed to assess the predictive values of individual sonographic findings of abnormal placentation to determine the candidates for segmental resectionStudy design: This was a retrospective review of 43 pregnancies with at least one prior cesarean delivery who received an ultrasound diagnosis of placenta previa or low-lying placenta with suspected abnormal placentation in the third trimester at our institution from 2015 through 2017. Sonographic images were reviewed by an investigator blinded to pregnancy outcome. Sonographic parameters were assessed including loss of retroplacental clear zone, irregularity and width of uterine-bladder interface, smallest myometrial thickness, presence of lacunar spaces, and bridging vessels. Diagnosis of placental invasion was based on histologic confirmation. Parameters were analyzed to predict candidates for conservative approach.Results: There were 27 cases with cesarean hysterectomy where as conservative approach was successful in 16 of the cases. Numbers of transfusions of packed red blood cells (2.6 vs. 1.7), fresh frozen plasma (2.3 vs. 0.9) and mean smallest retroplacental myometrial thickness (1.3 vs. 2.1 mm) were significantly different between the two groups (p < .05). Smallest retroplacental myometrial thickness was a significant predictor for the cases appropriate for successful conservative approach (Area Under Curve, AUC =0.911, p < .001), optimal cut off value was obtained at 1.6 mm with 94% sensitivity and 85% specificity.Conclusions: Our data showed that among some sonographic findings of abnormal placentation, smallest myometrial thickness was a significant predictor to determine candidates for conservative approach.

Impact of treatment satisfaction on quality of life of patients with acromegaly.

PURPOSE: To evaluate satisfaction of acromegalic subjects with their medical treatment and its contribution to their quality of life. METHODS: This cross-sectional study included a total of 159 medications used in 133 subjects with acromegaly (controlled n = 84 and uncontrolled n = 49, female/male: 81/52). Subjects were asked to complete questionnaires on symptoms of depression (BDI) and satisfaction with the medical therapy they received for acromegaly (TSQM). Acromegaly cases also completed Acromegaly Quality of Life Questionnaire (AcroQoL). RESULTS: Subjects on pegvisomant therapy scored lower on convenience (p = 0.007). Cases on combination therapy had lower domain scores for effectiveness, convenience and global satisfaction in comparison to the cases on monotherapy (p = 0.01, p = 0.01 and p = 0.01, respectively). The time elapsed since diagnosis and the duration of medical therapy were positively correlated with effectiveness score (r = 0.2, p = 0.007 and r = 0.2, p = 0.04, respectively). The AcroQoL score was positively correlated with all domains of TSQM (for effectiveness r = 0.2, p = 0.01; for side effects r = 0.3, p = 0.001; for convenience r = 0.3, p = 0.004 and for global satisfaction r = 0.2, p = 0.01). In contrast, the BDI score was inversely correlated with all domains of TSQM (for effectiveness r = -0.3, p = 0.001; for side effects r = -0.2, p = 0.006; for convenience r = -0.3, p < 0.001 and for global satisfaction r = -0.3, p = 0.001). CONCLUSION: In acromegaly, quality of life, status of depression and satisfaction of the subjects with their treatment are intercorrelated.
