Intraoperative image-guidance during robotic surgery: is there clinical evidence of enhanced patient outcomes?

BACKGROUND

To date, the benefit of image guidance during robot-assisted surgery (IGS) is an object of debate. The current study aims to address the quality of the contemporary body of literature concerning IGS in robotic surgery throughout different surgical specialties.

METHODS

A systematic review of all English-language articles on IGS, from January 2013 to March 2023, was conducted using PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases. Comparative studies that tested performance of IGS vs control were included for the quantitative synthesis, which addressed outcomes analyzed in at least three studies: operative time, length of stay, blood loss, surgical margins, complications, number of nodal retrievals, metastatic nodes, ischemia time, and renal function loss. Bias-corrected ratio of means (ROM) and bias-corrected odds ratio (OR) compared continuous and dichotomous variables, respectively. Subgroup analyses according to guidance type (i.e., 3D virtual reality vs ultrasound vs near-infrared fluoresce) were performed.

RESULTS

Twenty-nine studies, based on 11 surgical procedures of three specialties (general surgery, gynecology, urology), were included in the quantitative synthesis. IGS was associated with 12% reduction in length of stay (ROM 0.88; p = 0.03) and 13% reduction in blood loss (ROM 0.87; p = 0.03) but did not affect operative time (ROM 1.00; p = 0.9), or complications (OR 0.93; p = 0.4). IGS was associated with an estimated 44% increase in mean number of removed nodes (ROM 1.44; p < 0.001), and a significantly higher rate of metastatic nodal disease (OR 1.82; p < 0.001), as well as a significantly lower rate of positive surgical margins (OR 0.62; p < 0.001). In nephron sparing surgery, IGS significantly decreased renal function loss (ROM 0.37; p = 0.002).

CONCLUSIONS

Robot-assisted surgery benefits from image guidance, especially in terms of pathologic outcomes, namely higher detection of metastatic nodes and lower surgical margins. Moreover, IGS enhances renal function preservation and lowers surgical blood loss.

Return rate following a live birth obtained with ART: frequency and determinants

PURPOSE

To understand how often couples return to ART centres for a second child.

METHODS

Retrospective monocentric cohort study including women who had a first live birth with IVF. The primary objective was to assess the rate of those returning for a second child within five years of the previous pregnancy. The secondary aim was to disentangle the determinants of this rate.

RESULTS

A total of 374 patients were included, of whom 188 returned (50%, 95% CI 45-55%). Among those who did not return (n = 186), four (2%) referred to another ART Center and 24 were unreachable. Of the 158 contacted subjects that did not refer for ART, 53 (34%, 95% CI 27-41%) conceived naturally, 57 (36%, 95% CI 29-44%) abandoned their intent of parenthood, and 48 (30%, 95% CI 24-38%) unsuccessfully attempted natural conception. These 48 women (13%) who expressed interest in a second child but did not undergo ART were compared to those seeking a second pregnancy through ART. Baseline characteristics were similar except for an older age (Median 36, IQR: 34-38 vs 34, IQR: 32-36, p = 0.001). Additionally, in terms of IVF cycle characteristics, women who did not return were more likely to achieve their first pregnancy with a fresh transfer rather than a frozen transfer (75% vs 59%, p = 0.05). They also had a higher number of retrieved oocytes (Median 10, IQR: 7-13 vs 9, IQR: 5-12) and less frequently cryopreserved embryos (27% vs 52%, p = 0.003).

CONCLUSION

The proportion of couples who have conceived with ART and who are interested in having a second child is high. Our results underline the importance of paying more attention to the number of intended children, as this information could influence clinical management.

Women's quality of sleep and in vitro fertilization success

Women undergoing in vitro fertilization (IVF) are emotionally challenged. Anxiety, depression, and sleep disturbances are common complaints. The impact of these symptoms on IVF outcome is however debated. In this study, we aimed at investigating whether sleep quality and psychological health can affect the chances of success of the procedure. Women undergoing IVF were recruited at the time of oocytes retrieval. Women's sleep quality and psychological health was assessed using the Pittsburgh Sleep Quality Index (PSQI), the Fertility Problem Inventory (FPI), and the Hospital Anxiety and Depression Scale (HADS). Baseline characteristics and results of the three scales were compared between women who did and did not succeed. Overall, 263 women were included, of whom 81 had a clinical pregnancy (31%). As expected, successful women were younger, and their ovarian reserve was more preserved. FPI and HADS scores did not differ. Conversely, a statistically significant difference emerged for the PSQI score, the median [interquartile range] in pregnant and non-pregnant women being 4 [3-5] and 5 [3-7], respectively (p = 0.004). The crude and adjusted OR of pregnancy in women with a PSQI > 5 (indicating impaired sleep quality) was 0.46 (95% CI 0.25-0.86, p = 0.02) and 0.50 (95% CI: 0.26-0.94, p = 0.03), respectively. In conclusion, low sleep quality is common in women scheduled for IVF and could influence the success of the procedure.

P-726 Women’s quality of sleep and in vitro fertilization success

Study question

Can sleep quality and psychological health of women undergoing In Vitro Fertilization (IVF) affect the chances of success of the procedure?

Summary answer

Psychological health doesn’t seem to affect IVF outcomes while sleep disturbances are common in women undergoing IVF and could influence the success of the procedure.

What is known already

IVF is saddled with a significant emotional burden causing anxiety, depression, and sleep disturbances. Baseline high levels of stress seem to be negatively associated with IVF success whereas studies evaluating the effect of anxiety and depression are discordant. Investigating sleep disorders in this setting is particularly attracting because of the significant association with anxiety and stress and because it is a simple information to collect. In addition, sleep disorders could negatively affect IVF success, as it does for natural conceptions, due to the well-established association between sleep and the hormonal system. Evidence on this issue is however scant and inconclusive.

Study design, size, duration

This is a single-center prospective cohort study designed to examine whether the sleep quality and psychological health of women undergoing IVF affect the chances of success of the procedure. Two hundred sixty-three women undergoing IVF between September to December 2019 were enrolled. Baseline characteristics and women’s sleep quality and psychological health were compared between women who did and did not have a live birth.

Participants/materials, setting, methods

Inclusion criteria were admission for oocyte pick-up. Women with neurologic or psychiatric disorders, obstructive sleep apnea syndrome, anatomical factors that can reduce embryo implantation and limited understanding of the Italian language were excluded. Women’s sleep quality and psychological health were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Fertility Problem Inventory (FPI), and the Hospital Anxiety and Depression Scale (HADS).

Main results and the role of chance

Overall, 81 women had a live birth (31%). As expected, successful women were younger, and their ovarian reserve was more preserved. No significant group differences were detected for education, employment, parity, smoking status, body mass index and indication to IVF. FPI and HADS scores did not differ. Conversely, our findings revealed that sleep disturbances were associated with lower chances of live birth in IVF: a statistically significant difference emerged for the PSQI score, the median [interquartile range] in pregnant and non-pregnant women being 4 [3-5] and 5 [3-7], respectively (p = 0.004). The crude and adjusted OR of pregnancy in women with a PSQI &gt;5 (indicating impaired sleep quality) was 0.46 (95%CI: 0.25-0.86, p = 0.02) and 0.50 (95%CI: 0.26-0.94, p = 0.03), respectively.

Limitations, reasons for caution

Data were collected during treatment, which did not allow to properly investigate the association between sleep quality, infertility, and IVF itself. Sleep quality was assessed using a self-reported sleep measure (although validated and extensively used by clinicians and researchers), which does not ensure the objectivity of observations.

Wider implications of the findings

The assessment of sleep quality throughout the treatment period should be included as an important part of multidisciplinary clinical management of women undergoing IVF. Sleep quality of candidate mothers should be promoted by the implementation of prevention programmes and targeted interventions.

Anti-Müllerian hormone concentration as an indicator of female general health status: a cross-sectional study

RESEARCH QUESTION

To evaluate the correlation between clinical and hormonal parameters and comorbidity burden in Caucasian women presenting for fertility treatment.

DESIGN

Monocentric cross-sectional study including a cohort of 3163 Caucasian women seeking medical care for fertility treatment. All patients underwent centralized laboratory testing for hormonal assessment. Complete clinical and laboratory data from the entire cohort were retrospectively analysed. Comorbidity burden score was assessed by the Charlson Comorbidity Index (CCI; categorized as 0 versus 1 versus ≥2).

RESULTS

Descriptive statistics and regression models tested the associations between clinical and laboratory parameters and CCI. Among the entire cohort of patients, a CCI = 0 was found in 2977 women (94.1%), and CCI = 1 and CCI ≥2 were found in 113 (3.6%) and 73 (2.3%) patients, respectively. Age (P = 0.009), gravidity (P = 0.001), anti-Müllerian hormone (AMH, P < 0.001) and TSH (P = 0.003) values were significantly different among CCI groups. In regression models, age at presentation and AMH emerged as independent indicators of CCI ≥ 1. Age at presentation <36 years (odds ratio [OR] 1.742, 95% confidence interval [CI] 1.284-2.364) and an AMH concentration ≤2.3 ng/ml (OR 1.864, 95% CI 1.29-2.69) were the most informative cut-off values for CCI ≥ 1 in the study population.

CONCLUSIONS

A younger age at presentation and lower AMH concentrations are significant independent indicators of decreased general health in women requiring clinical evaluation for fertility treatment. As observed for sperm parameters in men, AMH might serve as a proxy of women's general health status.
