Can unexplained infertility be evaluated by a new immunological four-biomarkers panel? A pilot study

BACKGROUND

Inflammation and oxidative stress are known to be triggering factors for a decrease of the pregnancy rate like maternal immunosuppression. Under these circumstances our study was performed to verify four immunological biomarkers (IMMUNOX Panel) in terms of incidence in a sine-causa infertile population and the overall pregnancy rate when the Panel was showing some non-physiologic values.

METHODS

Sera of 86 women affected by unexplained infertility were screened for the IMMUNOX panel of biomarkers composed by: tumor necrosis factor alpha (TNF-α,) glycodelin (GLY), total oxidative status (TOS), and complement activity toxic factor (CATF). When at least one of the biomarkers tested was showing values outside the physiologic range, the woman was considered IMMUNOX-Positive.

RESULTS

The first data was indented to verify the incidence of the women with an IMMUNOX-positive panel. Results show that 19.8%, 18.6%, 25.6%, and 47.7% were IMMUNOX-positive for GLY, TNF-α, TOS and CATF respectively. The overall incidence of IMMUNOX-positive patients, with at least one biomarker positive was 70,9%. Subsequently we have analysed the correlation between IMMUNOX Panel positivity and the pregnancy rate. The pregnancy rate in a subgroup (N.=55) of the entire population tested (N.=86) was 2.9% and 36.6% for the IMMUNOX-positive and IMMUNOX-negative patients respectively.

CONCLUSIONS

Further validation studies are needed to prove that there is a correlation between unexplained infertility and immunological disorders screened by the IMMUNOX Panel, nevertheless our data shows that this diagnostic approach may be helpful to predict and to identify women at higher risk of IVF cycles failure.

Laparoscopic Versus Open Hysterectomy for Benign Disease in Uteri Weighing >1 kg: A Retrospective Analysis on 258 Patients

STUDY OBJECTIVE

To present a large single-center series of hysterectomies for uteri ≥1 kg and to compare the laparoscopic and open abdominal approach in terms of perioperative outcomes and complications.

DESIGN

A retrospective analysis of prospectively collected data (Canadian Task Force classification II-2).

SETTING

An academic research center.

PATIENTS

Consecutive women who underwent hysterectomy for uteri ≥1 kg between January 2000 and December 2016. Patients with a preoperative diagnosis of uterine malignancy or suspected uterine malignancy were excluded. The subjects were divided according to the intended initial surgical approach (i.e., open or laparoscopic). The 2 groups were compared in terms of intraoperative data and postoperative outcomes. Multivariable analysis was performed to identify possible independent predictors of overall complications. A subanalysis including only obese women was accomplished.

INTERVENTIONS

Total laparoscopic versus abdominal hysterectomy (±bilateral adnexectomy).

MEASUREMENTS AND MAIN RESULTS

Intra- and postoperative surgical outcomes. A total of 258 patients were included; 55 (21.3%) women were initially approached by open surgery and 203 (78.7%) by laparoscopy. Nine (4.4%) conversions from laparoscopic to open surgery were registered. The median operative time was longer in the laparoscopic group (120 [range, 50-360] vs 85 [range, 35-240] minutes, p = .014). The estimated blood loss (150 [range, 0-1700] vs 200 [50-3000] mL, p = .04), postoperative hemoglobin drop, and hospital stay (1 [range, 1-8] vs 3 [range, 1-8] days, p < .001) were lower among patients operated by laparoscopy. No difference was found between groups in terms of intra- and postoperative complications. However, the overall rate of complications (10.8% vs. 27.2%, p = .015) and the incidence of significant complications (defined as intraoperative adverse events or postoperative Clavien-Dindo ≥2 events, 4.4% vs 10.9%, p = .04) were significantly higher among patients who initially received open surgery. The laparoscopic approach was found to be the only independent predictor of a lower incidence of overall complications (odds ratio = 0.42; 95% confidence interval, 0.19-0.9). The overall morbidity of minimally invasive hysterectomy was lower also in the subanalysis concerning only obese patients.

CONCLUSION

In experienced hands and in dedicated centers, laparoscopic hysterectomy for uteri weighing ≥1 kg is feasible and safe. Minimally invasive surgery retains its well-known advantages over open surgery even in patients with extremely enlarged uteri.

Transvaginal contained tissue extraction after laparoscopic myomectomy: a cohort study

OBJECTIVE

To describe the technique and report perioperative outcomes of transvaginal contained extraction of surgical specimens at laparoscopic myomectomy.

DESIGN

Retrospective analysis of prospectively collected data.

SETTING

Two Italian referral centres for gynaecological minimally invasive surgery.

POPULATION

Consecutive patients who underwent laparoscopic myomectomy.

METHODS

Tissue extraction was accomplished following laparoscopic myomectomy in a specimen retrieval bag via a posterior colpotomy incision. If morcellation was necessary, this was performed extracorporeally, using a scalpel within the specimen retrieval pouch, whose edges were exteriorised through the vaginal introitus.

MAIN OUTCOME MEASURES

Intra- and postoperative complications.

RESULTS

A total of 316 women underwent transvaginal specimen retrieval with enclosed manual morcellation. The mean myomectomy specimen weight was 154 ± 128 g, and the mean operative time was 79 ± 26 minutes. No intraoperative complications occurred related to the specimen extraction or morcellation technique, or from rupture of the retrieval bag. Two (0.6%) women had a haemoperitoneum that spontaneously resolved and 16 (5.1%) had fever postoperatively. The final pathological diagnosis was benign in all cases. At the 30-day follow-up, no pelvic infection, vaginal dehiscence, or complaints of dyspareunia were recorded.

CONCLUSIONS

Contained transvaginal extraction of fibroid specimens can be performed safely and efficiently in most women undergoing laparoscopic myomectomy. This technique represents a valuable minimally invasive alternative to intracorporeal morcellation.

TWEETABLE ABSTRACT

Transvaginal contained morcellation at laparoscopic myomectomy is a valuable alternative to intracorporeal morcellation.

The effect of a uterine manipulator on the recurrence and mortality of endometrial cancer: a multi-centric study by the Italian Society of Gynecological Endoscopy

BACKGROUND

Although widely adopted, the use of a uterine manipulator during laparoscopic treatment of endometrial cancer represents a debated issue, and some authors hypothesize that it potentially may cause an increased risk of relapse, particularly at specific sites.

OBJECTIVE

Our aim was to evaluate the risk and site of disease recurrence, overall survival, and disease-specific survival in women who had laparoscopic surgery with and without the use of a uterine manipulator.

STUDY DESIGN

Data were reviewed from consecutive patients who had laparoscopic surgery for endometrial cancer staging in 7 Italian centers. Subjects were stratified according to whether a uterine manipulator was used during surgery; if so, the type of manipulator was identified. Multivariable analysis to correct for possible confounders and propensity score that matched the minimize selection bias were utilized. The primary outcome was the risk of disease recurrence. Secondary outcomes were disease-specific and overall survival and the site of recurrence, according to the use or no use of the uterine manipulator and to the different types of manipulators used.

RESULTS

We included 951 patients: 579 patients in the manipulator group and 372 patients in the no manipulator group. After a median follow-up period of 46 months (range,12-163 months), the rate of recurrence was 13.5% and 11.6% in the manipulator and no manipulator groups, respectively (P=.37). Positive lymph nodes and myometrial invasion of >50% were associated independently with the risk of recurrence after adjustment for possible confounders. The use of a uterine manipulator did not affect the risk of recurrence, both at univariate (odds ratio, 1.18; 95% confidence interval, 0.80-1.77) and multivariable analysis (odds ratio, 1.00; 95% confidence interval, 0.60-1.70). Disease-free, disease-specific, and overall survivals were similar between groups. Propensity-matched analysis confirmed these findings. The site of recurrence was comparable between groups. In addition, the type of uterine manipulator and the presence or not of a balloon at the tip of the device were not associated significantly with the risk of recurrence.

CONCLUSION

The use of a uterine manipulator during laparoscopic surgery does not affect the risk of recurrence and has no impact on disease-specific or overall survival and on the site of recurrence in women affected by endometrial cancer.

Structural Connectivity Analysis in Children with Segmental Callosal Agenesis

BACKGROUND AND PURPOSE

Segmental callosal agenesis is characterized by the absence of the intermediate callosal portion. We aimed to evaluate the structural connectivity of segmental callosal agenesis by using constrained spherical deconvolution tractography and connectome analysis.

MATERIALS AND METHODS

We reviewed the clinical-radiologic features of 8 patients (5 males; mean age, 3.9 years). Spherical deconvolution and probabilistic tractography were performed on diffusion data. Structural connectivity analysis, including summary network metrics, modularity analysis, and network consistency measures, was applied in 5 patients and 10 age-/sex-matched controls.

RESULTS

We identified 3 subtypes based on the position of the hippocampal commissure: beneath the anterior callosal remnant in 3 patients (type I), beneath the posterior callosal remnant in 3 patients (type II), and between the anterior and posterior callosal remnants in 2 patients (type III). In all patients, the agenetic segment corresponded to fibers projecting to the parietal lobe, and segmental Probst bundles were found at that level. Ectopic callosal bundles were identified in 3 patients. Topology analysis revealed reduced global connectivity in patients compared with controls. The network topology of segmental callosal agenesis was more variable across patients than that of the control connectomes. Modularity analysis revealed disruption of the structural core organization in the patients.

CONCLUSIONS

Three malformative subtypes of segmental callosal agenesis were identified. Even the absence of a small callosal segment may impact global brain connectivity and modularity organization. The presence of ectopic callosal bundles may explain the greater interindividual variation in the connectomes of patients with segmental callosal agenesis.

Laparoscopic Versus Open Hysterectomy for Benign Disease in Women with Giant Uteri (≥1500 g): Feasibility and Outcomes

STUDY

OBJECTIVE

To evaluate perioperative outcomes and complications of laparoscopic hysterectomy (LH) in women with giant uteri (≥1.5 kg) compared with open abdominal hysterectomy (AH), which is considered the reference.

DESIGN

A retrospective analysis of prospectively collected data (Canadian Task Force Classification II-2).

SETTING

An academic research center.

PATIENTS

All consecutive women who underwent hysterectomy for uteri weighing ≥1500 g (total = 51) between 2000 and 2015 were analyzed. Twenty-seven (53%) patients had been scheduled for the laparoscopic approach (LH), whereas 24 (48%) had been scheduled for AH.

INTERVENTIONS

Hysterectomy ± mono/bilateral salpingo-oophorectomy.

MAIN OUTCOME MEASURES

Perioperative details, incidence, severity, and type of complications were analyzed according to surgical approach (AH vs LH). We also evaluated the trends over time in terms of perioperative outcomes.

RESULTS

AH was associated with a shorter operative time (97.5 vs 160 minutes, p = .004) compared with LH. Blood loss (200 vs 225 mL, p = .21) and the decrease in postoperative hemoglobin (-1.2 vs -1.1, p = .89) were similar between AH and LH. Intra- and postoperative complications were similar between the 2 groups; however, hospital stay was significantly shorter in the LH group (median = 3 days vs 1 day, p < .001). A significant trend toward a progressive increase in the use of the minimally invasive approach was registered through the years (p = .001). Parallel to this increase, we observed a significant reduction in terms of length of stay. Moreover, a decrease in the total number of complications, mainly because of a decrease in the rate of early minor events, was observed through the years.

CONCLUSIONS

Our experience shows that LH can be considered a feasible procedure, even in cases of uteri ≥1.5 kg, with significant advantages over open surgery in terms of postoperative hospital stay.

Impact of endometriosis on surgical outcomes and complications of total laparoscopic hysterectomy

PURPOSE

Total laparoscopic hysterectomy (TLH) in the case of endometriosis may be extremely challenging. Our aim has been to analyze perioperative details and complications of TLH in women with vs. women without endometriosis.

METHODS

Consecutive women who underwent TLH for endometriosis (endometriosis group) were compared with consecutive patients who had TLH for other conditions (controls) in terms of perioperative outcomes. Patients in the endometriosis group were analyzed, according to the severity of the disease.

RESULTS

One-hundred and twelve women in the endometriosis group, 29 (25.9 %) with minimal-mild, and 83 (74.1 %) with moderate-severe stage disease (rAFS score), respectively, were compared with 572 controls. Conversion rate was 0.8 vs. 0.5 % (P = 0.51), and median operative time was 75 vs. 55 min (pxxx = x) in the endometriosis group vs.

CONTROLS

Intraoperative complications were similar between groups (P = 0.56). Postoperative complications occurred in 10 (12.3 %) women in the endometriosis group vs. 12 (3.3 %) among the controls (P = 0.002). The severity of complications according to Clavien-Dindo classification system was higher in the endometriosis group (Clavien-Dindo >2: 7.5 vs. 1.9 %). The risk of organ lesions, urinary lesions, postoperative complications, and severe adverse events was significantly higher in women with moderate-severe endometriosis vs.

CONTROLS

No differences between patients with minimal-mild endometriosis and controls were found.

CONCLUSION(S)

TLH in the case of endometriosis is associated with longer operative time and an almost fourfold increase in the risk and severity of complications compared with controls. In particular, the adjunctive risk of adverse events is specific for moderate/severe-stage disease but not for minimal/mild endometriosis.

Fertility rates, course of pregnancy and perinatal outcomes after laparoscopic ureterolysis for deep endometriosis: A long-term follow-up study

We evaluated fertility rates, pregnancy course and maternal/neonatal outcomes following laparoscopic ureterolysis for deep endometriosis. Data about women who underwent laparoscopic excision of ureteral endometriosis were analysed. After exclusion of women who underwent hysterectomy/bilateral adnexectomy at initial surgery, and those lost-to-follow-up or with follow-up <1 year, a total of 61 patients were included. Of them, 36 (59%) wished to conceive after surgery. Twenty women became pregnant: nine (45%) of them after assisted reproductive technologies. Twenty-six pregnancies were observed with four (15.6%) miscarriages. Median gestational week at delivery was 38 weeks + 2 days (range, 33 + 1-41 + 6), with three (13.6%) and two (9%) deliveries before 37 and 34 weeks, respectively. Nine caesarean sections were performed (40.9%). Fertility rates after laparoscopic ureterolysis are comparable to those of other women operated for other forms of deep endometriosis. Apart from a higher risk of caesarean and preterm birth, the course of pregnancy and peripartum outcomes appear encouraging.

Laparoscopic fertility-sparing surgery for early ovarian epithelial cancer: A multi-institutional experience

OBJECTIVE

There is as yet limited evidence about fertility-sparing surgery for early ovarian cancer (EOC) carried out laparoscopically. We sought to investigate the safety, adequacy and fertility outcome of ovarian cancer patients who underwent fertility-saving laparoscopic surgical staging using a multi-institutional sample.

METHODS

Prospectively collected data in five gynecologic oncology service databases were searched for epithelial EOC patients undergoing laparoscopic fertility-preserving surgery. Surgical, pathologic, oncologic and reproductive outcome data were analysed.

RESULTS

The study cohort consisted of 65 women. Median age of the patients was 33 (range: 21-42) years. In this cohort 36 (55.4%) and 29 (44.6%) patients were at low risk (FIGO stage IA G1-2) and high-risk (FIGO stage IA G3 or more), respectively. The disease was reclassified to a higher stage in 4 (6.1%) women. After a median follow up period of 38months (range: 2-144), the overall survival was 95.4% and recurrence-free survival 84.6%. Overall, there were 23 pregnancies in 22 women. After ovarian cancer treatment, 64.8% women reported pregnancy intent and 60% of these conceived spontaneously.

CONCLUSIONS

Laparoscopic staging may represent a viable option for premenopausal women seeking fertility preservation in the setting of early ovarian cancer. More research is needed to determine whether laparoscopy may offer reproductive benefits to this particular population.

Laparoscopic vs. open treatment of endometrial cancer in the elderly and very elderly: An age-stratified multicenter study on 1606 women

Objective To investigate in depth the effect of increasing age on the peri-operative outcomes of laparoscopic treatment for endometrial cancer, compared to open surgery, with stratification of patients according to the different definitions of elderly age used in the literature.

METHODS

Data of consecutive patients who underwent surgery for endometrial cancer staging at six centers were reviewed and analyzed according to surgical approach (laparoscopic or open), different definitions of elderly and very elderly age (≥65years, ≥75years, ≥80years), and class of age (<65; ≥65-<75; ≥75-80; ≥80years). Multivariable analysis to correct for possible confounders and propensity-score matching to minimize selection bias were used.

RESULTS

A total of 1606 patients were included: 938 and 668 patients received laparoscopic and open surgery, respectively. With increasing age, fewer patients received laparoscopy (P<0.001 with ANOVA). The percentage of patients who received lymphadenectomy declined significantly in both groups for age ≥80years. Blood transfusions, incidence and severity of post-operative complications, and hospital stay were significantly lower among patients who had laparoscopy both in younger (<65years) and elderly (whether defined as ≥65 or ≥75years) patients, with no effect of age on any of the characteristics analyzed (

ANOVA

P>0.05). The same tendency was observed among very-elderly patients (≥80years). Multivariable and propensity score-matched analysis confirmed these findings.

CONCLUSIONS

Laparoscopy for staging endometrial cancer retains its advantages over open surgery even in elderly and very-elderly patients. Our data strongly suggest that minimally-invasive surgery is advantageous even among subjects ≥80years.

Laparoscopic Management of Ovarian Cancer Patients With Localized Carcinomatosis and Lymph Node Metastases: Results of a Retrospective Multi-institutional Series

STUDY OBJECTIVE

To investigate the feasibility and safety of laparoscopic cytoreduction in ovarian cancer patients with localized carcinomatosis or lymph node involvement.

DESIGN

Retrospective cohort study (Canadian Task Force classification II-2).

SETTING

Multi-institutional study performed in 6 referral gynecologic oncology units.

PATIENTS

Between June 2005 and December 2014, preoperatively presumed early-stage ovarian cancer patients, who accidentally revealed localized carcinomatosis or lymph node involvement at laparoscopic evaluation or at postoperative pathological examination managed by the laparoscopic approach.

INTERVENTIONS

All patients with limited carcinomatosis and/or lymph node metastases underwent complete laparoscopic cytoreduction.

MEASUREMENTS AND RESULTS

Sixty-nine patients were included in the analysis. Twenty-eight (40.6%) patients were staged III C because they had lymph node metastases. Pelvic lymphadenectomy was performed in 75.4% of cases, whereas aortic lymphadenectomy was performed in 79.7% of cases. Lymph node metastases were found in pelvic and aortic regions in 11 and 13 patients, respectively, whereas 4 patients had lymph node metastases in both regions. Twelve (17.4%) patients underwent complete pelvic peritonectomy because of the presence of nodules localized in several pelvic region sites. As of May 2015, the median follow-up was 35 months, and the median disease-free survival was 29 months. The 2-year disease-free survival rate was 77.1%, whereas the 2-year overall survival rate was 90.6%. The median time to recurrence was 26 months (range, 6 -55 months); 15 (21.7%) patients developed recurrence.

CONCLUSION

The present study shows the technical and clinical feasibility of laparoscopic cytoreduction in ovarian cancer patients with limited carcinomatosis or lymph node involvement.

TVT for the treatment of urodynamic stress incontinence: Efficacy and adverse effects at 13-year follow-up

AIM

To assess long-term subjective, objective, and urodynamic outcomes of retropubic mid-urethral slings at 13-year follow-up.

METHODS

This was a prospective observational study. Consecutive women with proven urodynamic stress incontinence were treated with standard retropubic tension free vaginal tape (TVT). Patients with mixed incontinence and/or anatomic evidence of pelvic organ prolapse were excluded. All the included patients underwent preoperative clinical and urodynamic evaluations. During follow-up examinations, women were assessed for subjective satisfaction and objective cure rates. The Cox model was used in order to investigate factors predicting the risk of recurrent stress urinary incontinence (SUI), over the study period.

RESULTS

Overall, 55 patients were suitable for the analysis. At 13-year follow-up, 47 out of 55 (85.5%) patients declared themselves cured (p-for-trend 0.02) and 48 out of 58 (87.2%) were at least improved (p-for-trend 0.07). No significant deterioration of objective cure rates was observed over time (P = 0.29). At the time of the last evaluation, 50 out of 55 (90.9%) women were objectively cured; urodynamic evaluation confirmed this finding in 49 (89.1%) patients. Considering factors predictive of SUI recurrence, we observed that, via multivariate analysis, obesity (HR 7.2; P = 0.01) and maximum detrusor pressure during the voiding phase ≤29 cmH₂ O (HR 8.0; P = 0.01) were the only independent predictors of recurrent SUI.

CONCLUSION

Our data confirmed that TVT is a highly effective and safe procedure also at 13-year follow-up. Interestingly, we observed a significant decrease of subjective satisfaction over time. Neurourol. Urodynam. 36:192-197, 2017. © 2015 Wiley Periodicals, Inc.

Position in the second stage of labour and de novo onset of post-partum urinary incontinence

INTRODUCTION AND HYPOTHESIS

The aim of this study was to evaluate the role of the maternal position at the time of delivery on the onset of de novo symptoms of urinary incontinence (UI) in the post-partum period.

METHODS

This prospective study evaluated the data of consecutive women undergoing labour and delivery, between January 2014 and July 2014. We included only women with a singleton pregnancy undergoing vaginal delivery. During the study period, patients chose to deliver in the position that they considered the most comfortable. The onset of UI was evaluated according to the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-sf).

RESULTS

Overall, 716 primiparous women were included in the study. Sixty women refused the 12-week post-partum interview (8.4%). Women were divided in two groups: 296 women (45.1%) who chose an upright position during delivery (group 1) and 360 women (54.9%) who chose a supine position (group 2). Group 1 had a significantly lower episiotomy rate, but a higher rate of greater than second degree perineal tears. In group 1 we found a significantly lower rate of de novo UI (40.5% vs 48.9%, p = 0.03) and in particular of stress urinary incontinence. Via multivariate analysis, birth position was the only factor correlating with the occurrence of urinary incontinence in the post-partum period (OR: 1.52; 95%CI: 1.06, 2.18; p = 0.02).

CONCLUSIONS

Upright positions at delivery are related to a lower episiotomy rate and a higher rate of greater than second degree perineal tears. Supine positions are an independent risk factor for the onset of de novo UI.
