Non-alcoholic fatty liver disease (NAFLD) is the most common form of liver disease and leading cause of cirrhosis in the United States and developed countries. NAFLD is closely associated with ...obesity, insulin resistance and metabolic syndrome, significantly contributing to the exacerbation of the latter. Although NAFLD represents the hepatic component of metabolic syndrome, it can also be found in patients prior to their presentation with other manifestations of the syndrome. The pathogenesis of NAFLD is complex and closely intertwined with insulin resistance and obesity. Several mechanisms are undoubtedly involved in its pathogenesis and progression. In this review, we bring together the current understanding of the pathogenesis that makes NAFLD a systemic disease.
Laparoscopic mesh sacropexy (LS) or transvaginal mesh repair (TVM) are surgical techniques used to treat cystoceles. Health authorities have highlighted the need for comparative studies to evaluate ...the safety of surgeries with meshes.
To compare the rate of complications, and functional and anatomical outcomes between LS and TVM.
Multicenter randomized controlled trial from October 2012 to April 2014 in 11 French public hospitals. Women with cystocele stage ≥2 (pelvic organ prolapse quantification), aged 45–75 yr, without previous prolapse surgery.
Synthetic nonabsorbable mesh placed in the vesicovaginal space, sutured to the promontory (LS) or maintained by arms through pelvic ligaments (TVM).
Rate of surgical complications ≥grade II according to the modified Clavien–Dindo classification at 1 yr. Secondary outcomes were reintervention rate, and functional and anatomical results.
A total of 130 women were randomized in LS and 132 in TVM; five women withdrew before intervention, leaving 129 in LS and 128 in TVM. The rate of complications ≥grade II was lower after LS than after TVM, but did not meet statistical significance (17% vs 26%, treatment difference 8.6% 95% confidence interval, CI −1.5 to 18; p=0.088). The rate of complications of grade III or higher was nonetheless significantly lower after LS (LS=0.8%, TVM=9.4%, treatment difference 8.6% 95% CI 3.4%; 15%; p=0.001). LS was converted to TVM in 6.3%. The total reoperation rate was lower after LS but did not meet statistical significance (LS=4.7%, TVM=10.9%, treatment difference 6.3% 95% CI −0.4 to 13.3; p=0.060). There was no difference in symptoms, quality of life, improvement, composite definition of success, anatomical results rates between groups except for the vaginal apex and length, and dyspareunia (in favor of LS).
LS is a valuable option for primary repair of cystocele in sexually active patients. LS is safer than TVM, but may not be feasible in all cases. Both techniques offer same functional outcomes, success rates, and anatomical outcomes, but sexual function is better preserved by LS.
Our study demonstrates that laparoscopic sacropexy (LS) is a valuable option for primary repair of cystocele. LS offers equivalent success rates to vaginal mesh procedures, but is safer with a lower rate of complications and reoperations, and sexual function is better preserved.

Introduction
The aim of this study is to evaluate the utility of digital examination in addition to ultrasonic measurement of cervical length for predicting spontaneous preterm delivery in women with ...threatened preterm labor.
Material and methods
This was a prospective cohort study in Strasbourg University Hospital, France, between January 2013 and January 2015. All women with a singleton pregnancy hospitalized with threatened preterm labor between 23 and 34 weeks of gestation were included. Cases of iatrogenic preterm delivery were excluded. A multivariable logistic regression model to estimate the significant predictive parameters of spontaneous preterm delivery was performed. The primary endpoint of our study was a preterm birth before 34 weeks of gestation.
Results
A total of 395 women were included in our study. The rate of preterm delivery before 34 weeks was 13%. In univariate analysis every single cervical parameter assessed by the digital examination and all the ultrasound parameters were significantly associated with preterm delivery. The final model included five variables predicting preterm birth: visualization of the membranes at the speculum examination (OR 15.8, 95% CI 2.43–146), ultrasound cervical length (OR 0.82, 95% CI 0.75–0.89), signs of inflammation (OR 6.23, 95% CI 2.07–22.9), gestational age on admission (OR 0.84, 95% CI 0.71–1.0), and presence of vaginal infection (OR 4.28, 95% CI 1.52–12.7). None of the cervical parameters assessed by the digital examination provided additional predictive value of preterm delivery.
Conclusion
Our study suggests that digital examination does not add to the information given by vaginal ultrasound evaluation in predicting preterm labor.
Objective
To develop and evaluate a non-invasive surgical assistance based on augmented reality (AR) in the detection of ureters on animal model.
Method
After an experimental prototyping step on two ...pigs to determine the optimal conditions for visualization of the ureter in AR, three pigs were operated three times at 1 week intervals. The intervention consisted of an identification of the ureter, with and without the assistance of AR. At the end of the intervention, a clip was placed on the AR-proposed ureter to evaluate its accuracy. By doing a cone beam computed tomography, we measured the distance between the contrasted ureter and the clips in the acquired volume. Thirteen videos were recorded, allowing subsequent evaluation of the clinical relevance of the device.
Results
The feasibility of the technique has been confirmed. The margin of error was 1.77 mm (± 1.56 mm) for ureter localization accuracy. In order to evaluate the perceived relevance and accuracy in the detection of AR-assisted ureter, 58 gynecological surgeons were shown the videos then questioned. Of the 754 responses obtained (13 videos × 58 surgeons), the ureter was identified in direct vision in 31.2% of cases versus 81.7% in AR (
p
value 3.62 × 10
−7
). When looking at pigs that had already had one or two operations, the ureter was identified in only 16% of cases with direct vision compared to 76.1% with AR (
p
-value 5.48 × 10
−19
). In addition, 67% of surgeons felt that AR allowed them to better identify the ureters and 61% that AR reconstruction was accurate.
Conclusion
This first AR device showed a satisfactory precision in the detection of ureters with a favorable opinion of surgeons. This surgical assistance system could be helpful in the performance of difficult procedures, for example in the case of patients, which have undergone multiple surgeries in the past.
Objective
To describe the possible difficulties encountered in the event of laparoscopic sacrocolpopexy for vaginal vault prolapse and corresponding avoidance strategies.
Methods
Video recordings of ...different laparoscopic sacrocolpopexies for vaginal vault prolapse showing various situations and difficulties. University Teaching Hospital of Strasbourg.
Results
Although laparoscopic sacrocolpopexy for vaginal vault prolapse is becoming more common, achieving a good outcome remains challenging, especially with the vesicovaginal dissection. Bladder injuries are not rare and occur in about 2 to 6% of cases. Vaginal perforation is less common, but remains a risk. This video illustrates possible difficulties encountered and presents various strategies to avoid them. Several tips on exposing structures and following anatomical landmarks are described.
Conclusion
Knowing how to avoid these surgical traps will help trainee urogynecologic surgeons to perform laparoscopic sacrocolpopexy for vaginal vault prolapse.
Background Radio(chemo)therapy is often required in pelvic malignancies (cancer of the anus, rectum, cervix). Direct irradiation adversely affects ovarian and endometrial function, compromising the ...fertility of women. While ovarian transposition is an established method to move the ovaries away from the radiation field, surgical procedures to displace the uterus are investigational. This study demonstrates the surgical options for uterine displacement in relation to the radiation dose received. Methods The uterine displacement techniques were carried out sequentially in a human female cadaver to demonstrate each procedure step by step and assess the uterine positions with dosimetric CT scans in a hybrid operating room. Two treatment plans (anal and rectal cancer) were simulated on each of the four dosimetric scans (1. anatomical position, 2. uterine suspension of the round ligaments to the abdominal wall 3. ventrofixation of the uterine fundus at the umbilical level, 4. uterine transposition). Treatments were planned on EclipseR System (Varian Medical SystemsR,USA) using Volumetric Modulated Arc Therapy. Data about maximum (Dmax) and mean (Dmean) radiation dose received and the volume receiving 14 Gy (V14Gy) were collected. Results All procedures were completed without technical complications. In the rectal cancer simulation with delivery of 50 Gy to the tumor, Dmax, Dmean and V14Gy to the uterus were respectively 52,8 Gy, 34,3 Gy and 30,5cc (1), 31,8 Gy, 20,2 Gy and 22.0cc (2), 24,4 Gy, 6,8 Gy and 5,5cc (3), 1,8 Gy, 0,6 Gy and 0,0cc (4). For anal cancer, delivering 64 Gy to the tumor respectively 46,7 Gy, 34,8 Gy and 31,3cc (1), 34,3 Gy, 20,0 Gy and 21,5cc (2), 21,8 Gy, 5,9 Gy and 2,6cc (3), 1,4 Gy, 0,7 Gy and 0,0cc (4). Conclusions The feasibility of several uterine displacement procedures was safely demonstrated. Increasing distance to the radiation field requires more complex surgical interventions to minimize radiation exposure. Surgical strategy needs to be tailored to the multidisciplinary treatment plan, and uterine transposition is the most technically complex with the least dose received.
To evaluate the impact of laparoscopic excision of lesions on deep endometriosis-related infertility.
Retrospective study.
Endometriosis tertiary referral center (Canadian Task Force II-2).
A group ...of 115 patients who had undergone laparoscopic surgery for infertility with histologic confirmation of deep endometriosis.
Patient medical records and operative reports were reviewed. Telephone interviews were conducted for long-term follow-up of fertility outcomes.
Evaluation of fertility outcome after laparoscopic treatment of deep endometriosis by spontaneous conception and by assisted reproductive technology (ART) correlated with lesion number, size, and location (anterior, posterolateral, pouch of Douglas, and multiple locations). After a mean follow-up of 22 months the overall pregnancy rate was 54.78% (n = 63) with a live-birth rate of 42.6% (n = 49). Among those patients given the chance to conceive spontaneously (n = 70), the overall pregnancy rate was 60% (n = 42): 38.5% (n = 27) spontaneously and 21.4% (n = 15) by ART. The removal of multiple lesions was associated with a higher pregnancy rate after surgery. When comparing isolated lesion size and disease location, there was no difference in pregnancy rate. Furthermore, those patients who underwent surgical eradication of the disease for the first time had a higher pregnancy rate (odds ratio, 4.18).
This study demonstrates that laparoscopic excision of deep endometriosis enhances pregnancy rate, by both spontaneous conception and ART. First surgical treatment of multiple lesions was associated with higher pregnancy rates, whereas isolated lesions influenced the pregnancy rate irrespective of their location and size.
Abstract Objective The widespread diffusion of laparoscopic sacrocolpopexy in the management of female genital organ prolapse is hampered by its presumed length and technical difficulties. The aim of ...our study was to analyse the learning curve of a senior urogynecologic surgeon who was initiated into this technique. Study design The first 48 laparoscopic sacrocolpopexies performed by the same surgeon were analysed retrospectively for pre-operative, operative and post-operative data. At the time of the study, patients were asked about their degree of satisfaction by an anonymous questionnaire. To discover a turning point, the duration of each procedure was reported and the study population was divided into 8 equal groups of 6 interventions each, classed chronologically. Statistical analysis was carried out by Mauchly's sphericity test and then by Student–Newman – Keul's test. Other descriptive statistics were computed with the use of standard methods for means, medians and proportions. Results The mean operative time was of 236.9 min. The learning curve showed a linear decrease in the duration of surgery with a turning point after 18–24 procedures ( p < 0.001). It was marked by 2 (4.1%) minor operative complications (2 cystostomies) and 2 immediate post-operative ones: one port-site hernia and one case of urinary retention. At 1 month, 1 patient (2.2%) presented an erosion of the posterior mesh. The mean follow-up was of 15.8 months. During this period, 2 patients (4.1%) presented with a recurrence of prolapse and 6 (12.5%) with de novo stress urinary incontinence. Forty-five patients (93.7%) answered an anonymous questionnaire regarding satisfaction: 40/45 (88.8%) were totally satisfied, 4 (8.8%) moderately and 1 (2.2%) not satisfied. Conclusions The learning curve of laparoscopic sacrocolpopexy shows a steady decrease in the duration of surgery. A turning point is observed after 18–24 procedures. During the learning curve there is no increased morbidity. Anatomical and functional results at short and medium terms are similar to those reported in the literature.
Introduction: Borderline ovarian tumours (BOT) represent 10–20% of epithelial tumours of the ovary. Although their prognosis is excellent, the recurrence rate can be as high as 30%, and recurrence in ...the infiltrative form accounts for 3% to 5% of recurrences. Affecting, in one third of cases, women of childbearing age, the surgical strategy with ovarian conservation is now recommended despite a significant risk of recurrence. Few studies have focused exclusively on patients who have received ovarian conservative treatment in an attempt to identify factors predictive of recurrence and the impact on fertility. The objective of this study was to identify the risk factors for recurrence of BOT after conservative treatment and the impact on fertility. Material and methods: This was a retrospective, multicentre study of women who received conservative surgery for BOT between February 1997 and September 2020. We divided the patients into two groups, the “R group” with recurrence and the “NR group” without recurrence. Results: Of 175 patients included, 35 had a recurrence (R group, 20%) and 140 had no recurrence (NR group, 80%). With a mean follow-up of 30 months (IQ 8–62.5), the overall recurrence rate was 20%. Recurrence was BOT in 17.7% (31/175) and invasive in 2.3% (4/175). The mean time to recurrence was 29.5 months (IQ 16.5–52.5). Initial complete peritoneal staging (ICPS) was performed in 42.5% of patients (n = 75). In multivariate analysis, age at diagnosis, nulliparity, advanced FIGO stage, the presence of peritoneal implants, and the presence of a micropapillary component for serous tumours were factors influencing the occurrence of recurrence. The post-surgery fertility rate was 67%. Conclusion: This multicentre study is to date one of the largest studies analysing the risk factors for recurrence of BOT after conservative surgery. Five risk factors were found: age at diagnosis, nulliparity, advanced FIGO stage, the presence of implants, and a micropapillary component. Only 25% of the patients with recurrence underwent ICPS. These results reinforce the interest of initial peritoneal staging to avoid ignoring an advanced tumour stage.
