Surgical approach to hysterectomy for benign gynaecological disease.

BACKGROUND: Currently, there are five major approaches to hysterectomy for benign gynaecological disease: abdominal hysterectomy (AH), vaginal hysterectomy (VH), laparoscopic hysterectomy (LH), robotic-assisted hysterectomy (RH) and vaginal natural orifice hysterectomy (V-NOTES). Within the LH category we further differentiate the laparoscopic-assisted vaginal hysterectomy (LAVH) from the total laparoscopic hysterectomy (TLH) and single-port laparoscopic hysterectomy (SP-LH). OBJECTIVES: To assess the effectiveness and safety of different surgical approaches to hysterectomy for women with benign gynaecological conditions. SEARCH METHODS: We searched the following databases (from their inception to December 2022): the Cochrane Gynaecology and Fertility Specialised Register of Controlled Trials, CENTRAL, MEDLINE, Embase, CINAHL and PsycINFO. We also searched the trial registries and relevant reference lists, and communicated with experts in the field for any additional trials. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in which clinical outcomes were compared between one surgical approach to hysterectomy and another. DATA COLLECTION AND ANALYSIS: At least two review authors independently selected trials, assessed risk of bias and performed data extraction. Our primary outcomes were return to normal activities, satisfaction and quality of life, intraoperative visceral injury and major long-term complications (i.e. fistula, pelvic-abdominal pain, urinary dysfunction, bowel dysfunction, pelvic floor condition and sexual dysfunction). MAIN RESULTS: We included 63 studies with 6811 women. The evidence for most comparisons was of low or moderate certainty. The main limitations were poor reporting and imprecision. Vaginal hysterectomy (VH) versus abdominal hysterectomy (AH) (12 RCTs, 1046 women) Return to normal activities was probably faster in the VH group (mean difference (MD) -10.91 days, 95% confidence interval (CI) -17.95 to -3.87; 4 RCTs, 274 women; I2 = 67%; moderate-certainty evidence). This suggests that if the return to normal activities after AH is assumed to be 42 days, then after VH it would be between 24 and 38 days. We are uncertain whether there is a difference between the groups for the other primary outcomes. Laparoscopic hysterectomy (LH) versus AH (28 RCTs, 3431 women) Return to normal activities may be sooner in the LH group (MD -13.01 days, 95% CI -16.47 to -9.56; 7 RCTs, 618 women; I2 = 68%, low-certainty evidence), but there may be more urinary tract injuries in the LH group (odds ratio (OR) 2.16, 95% CI 1.19 to 3.93; 18 RCTs, 2594 women; I2 = 0%; moderate-certainty evidence). This suggests that if the return to normal activities after abdominal hysterectomy is assumed to be 37 days, then after laparoscopic hysterectomy it would be between 22 and 25 days. It also suggests that if the rate of ureter injury during abdominal hysterectomy is assumed to be 0.2%, then during laparoscopic hysterectomy it would be between 0.2% and 2%. We are uncertain whether there is a difference between the groups for the other primary outcomes. LH versus VH (22 RCTs, 2135 women) We are uncertain whether there is a difference between the groups for any of our primary outcomes. Both short- and long-term complications were rare in both groups. Robotic-assisted hysterectomy (RH) versus LH (three RCTs, 296 women) None of the studies reported satisfaction rates or quality of life. We are uncertain whether there is a difference between the groups for our other primary outcomes. Single-port laparoscopic hysterectomy (SP-LH) versus LH (seven RCTs, 621 women) None of the studies reported satisfaction rates, quality of life or major long-term complications. We are uncertain whether there is a difference between the groups for rates of intraoperative visceral injury. Total laparoscopic hysterectomy (TLH) versus laparoscopic-assisted vaginal hysterectomy (LAVH) (three RCTs, 233 women) None of the studies reported satisfaction rates or quality of life. We are uncertain whether there is a difference between the groups for rates of intraoperative visceral injury or major long-term complications. Transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) versus LH (two RCTs, 96 women) We are uncertain whether there is a difference between the groups for rates of bladder injury. Our other primary outcomes were not reported. Overall, adverse events were rare in the included studies. AUTHORS' CONCLUSIONS: Among women undergoing hysterectomy for benign disease, VH appears to be superior to AH. When technically feasible, VH should be performed in preference to AH because it is associated with faster return to normal activities, fewer wound/abdominal wall infections and shorter hospital stay. Where VH is not possible, LH has advantages over AH including faster return to normal activities, shorter hospital stay, and decreased risk of wound/abdominal wall infection, febrile episodes or unspecified infection, and transfusion. These advantages must be balanced against the increased risk of ureteric injury and longer operative time. When compared to LH, VH was associated with no difference in time to return to normal activities but shorter operative time and shorter hospital stay. RH and V-NOTES require further evaluation since there is a lack of evidence of any patient benefit over conventional LH. Overall, the evidence in this review has to be interpreted with caution as adverse event rates were low, resulting in low power for these comparisons. The surgical approach to hysterectomy should be discussed with the patient and decided in the light of the relative benefits and hazards. Surgical expertise is difficult to quantify and poorly reported in the available studies and this may influence outcomes in ways that cannot be accounted for in this review. In conclusion, when VH is not feasible, LH has multiple advantages over AH, but at the cost of more ureteric injuries. Evidence is limited for RH and V-NOTES.

Social Support Among Women With Potential Essure-Related Complaints: Analysis of Facebook Group Content.

BACKGROUND: Social support groups are an important resource for people to cope with problems. Previous studies have reported the different types of support in these groups, but little is known about the type of reactions that sharing of personal experiences induce among members. It is important to know how and to what extent members of support groups influence each other regarding the consumption of medical care. We researched this in a web-based Facebook group of women sterilized with Essure. Essure was a device intended for permanent contraception. From 2015 onward, women treated with Essure for tubal occlusion raised safety concerns and numerous complaints. OBJECTIVE: This study aimed to evaluate the use of social support in a Facebook community named "Essure problemen Nederland" (EPN; in English, "Essure problems in the Netherlands"). METHODS: All posts in the closed Facebook group EPN between March 8 and May 8, 2018, were included. In total, 3491 Facebook posts were analyzed using a modified version of the Social Support Behavior Codes framework created by Cutrona and Suhr in 1992. Posts were abstracted and aggregated into a database. Two investigators evaluated the posts, developed a modified version of the Social Support Behavior Codes framework, and applied the codes to the collected data. RESULTS: We found that 92% of messages contained a form of social support. In 68.8% of posts, social support was provided, and in 31.2% of posts, social support was received. Informational and emotional support was the most frequently used form of provided social support (40.6% and 55.5%, respectively). The same distribution was seen with received social support: informational support in 81.5% and emotional support in 17.4% of cases. Our analysis showed a strong correlation between providing or receiving social support and the main form of social support (P<.001). In a total of only 74 (2.2%) cases, women advised each other to seek medical care. CONCLUSIONS: The main purpose of women in the EPN Facebook group was to provide and receive informational or emotional support or both.

Menstrual abnormalities after COVID-19 vaccination in the Netherlands: A description of spontaneous and longitudinal patient-reported data.

AIMS: During the COVID-19 vaccination campaigns, the number of reports of menstrual abnormalities increased rapidly. Here, we describe the nature and potential risk factors associated with menstrual abnormalities based on spontaneously reporting data as well as data from a prospective cohort event monitoring (CEM) study as these are poorly studied. METHODS: Reports of menstrual abnormalities received by the Netherlands Pharmacovigilance Centre Lareb in the spontaneous reporting system between February 2021 and April 2022 were summarized. In addition, logistic regression analysis was performed on the reported menstrual abnormalities in the CEM study to assess the association between person characteristics, prior SARS-CoV-2 infection and use of hormonal contraceptives and the occurrence of menstrual abnormalities after vaccination. RESULTS: We analysed over 24 000 spontaneous reports of menstrual abnormalities and over 500 episodes (among 16 929 included women) of menstrual abnormalities in the CEM study. The CEM study showed an incidence of 41.4 per 1000 women aged ≤54 years. Amenorrhoea/oligomenorrhoea and heavy menstrual bleeding collectively accounted for about half of all abnormalities reported. Significant associations were observed for the age group 25-34 years (odds ratio 2.18; 95% confidence interval 1.45-3.41) and the Pfizer vaccine (odds ratio 3.04; 95% confidence interval 2.36-3.93). No association was observed for body mass index and presence of most comorbidities assessed. CONCLUSION: The cohort study showed a high incidence of menstrual disorders among women aged ≤54 years, and this observation was supported by the analysis of spontaneous reports. This suggests that a relation between COVID-19 vaccination and menstrual abnormalities is plausible and should be further investigated.

Male or female sterilization - the decision making process: Counselling and regret.

OBJECTIVE(S): To analyze the decision-making process of both male and female sterilization in order to improve counselling and prevent regret after sterilization in the future. STUDY DESIGN: An online questionnaire regarding sterilization (counselling, sources of information and regret) was promoted on Facebook, Twitter and LinkedIn. A total of 1107 men and women who had undergone or considered sterilization in the Netherlands filled in the questionnaire. RESULTS: A total of 88.9 % of the sterilized group and 67.4 % in the considered group responded that they felt well informed when they considered sterilization. However, less than half of the participants in both groups knew about all different sterilization methods. In both groups participants reported they consulted their partner the most when they considered sterilization. After sterilization 7.7 % reported having regret. Regret was reported more often when participants were sterilized ≤ 30 years. Most important reasons for regret reported by males were complications, pain, a new wish to conceive and divorce/remarriage. Most important reasons for regret reported by females were pain, complications, a new wish to conceive and menstrual symptoms. A total of 21.1 % in the sterilized and 38.0 % in the considered group responded they would have liked to use a decision aid when they considered sterilization. CONCLUSIONS: Findings of this study provide insight in the decision-making process regarding sterilization. There is a lack of knowledge of different methods of sterilization and 7.7% regrets their sterilization afterwards. Furthermore, the results show an importance of developing a decision aid for couples considering sterilization.

Levonorgestrel-releasing intrauterine system versus endometrial ablation for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding affects the physical functioning and social well-being of many women. The levonorgestrel-releasing intrauterine system and endometrial ablation are 2 frequently applied treatments in women with heavy menstrual bleeding. OBJECTIVE: This study aimed to compare the effectiveness of the levonorgestrel-releasing intrauterine system with endometrial ablation in women with heavy menstrual bleeding. STUDY DESIGN: This multicenter, randomized controlled, noninferiority trial was performed in 26 hospitals and in a network of general practices in the Netherlands. Women with heavy menstrual bleeding, aged 34 years and older, without a pregnancy wish or intracavitary pathology were randomly allocated to treatment with either the levonorgestrel-releasing intrauterine system (Mirena) or endometrial ablation, performed with a bipolar radiofrequency device (NovaSure). The primary outcome was blood loss at 24 months, measured with a Pictorial Blood Loss Assessment Chart score. Secondary outcomes included reintervention rates, patient satisfaction, quality of life, and sexual function. RESULTS: We registered 645 women as eligible, of whom 270 women provided informed consent. Of these, 132 women were allocated to the levonorgestrel-releasing intrauterine system (baseline Pictorial Blood Loss Assessment Chart score, 616) and 138 women to endometrial ablation (baseline Pictorial Blood Loss Assessment Chart score, 630). At 24 months, mean Pictorial Blood Loss Assessment Chart scores were 64.8 in the levonorgestrel-releasing intrauterine system group and 14.2 in the endometrial ablation group (difference, 50.5 points; 95% confidence interval, 4.3-96.7; noninferiority, P=.87 [25 Pictorial Blood Loss Assessment Chart point margin]). Compared with 14 women (10%) in the endometrial ablation group, 34 women (27%) underwent a surgical reintervention in the levonorgestrel-releasing intrauterine system group (relative risk, 2.64; 95% confidence interval, 1.49-4.68). There was no significant difference in patient satisfaction and quality of life between the groups. CONCLUSION: Both the levonorgestrel-releasing intrauterine system and endometrial ablation strategies lead to a large decrease in menstrual blood loss in women with heavy menstrual bleeding, with comparable quality of life scores after treatment. Nevertheless, there was a significant difference in menstrual blood loss in favor of endometrial ablation, and we could not demonstrate noninferiority of starting with the levonorgestrel-releasing intrauterine system. Women who start with the levonorgestrel-releasing intrauterine system, a reversible and less invasive treatment, are at an increased risk of needing additional treatment compared with women who start with endometrial ablation. The results of this study will enable physicians to provide women with heavy menstrual bleeding with the evidence to make a well-informed decision between the 2 treatments.

Incidence of endometrioid and clear-cell ovarian cancer in histological proven endometriosis: the ENOCA population-based cohort study.

BACKGROUND: Several studies have suggested that endometriosis is associated with an increased risk of ovarian cancer, especially for the clear-cell and endometrioid subtypes. However, previous studies lack sufficient power or diagnostic certainty. OBJECTIVE: The objective of the study was to assess the association between histologically proven endometriosis and ovarian cancer in a large population-based cohort study. STUDY DESIGN: We identified 131,450 women with a histological diagnosis of endometriosis between 1990 and 2015 from the Dutch nationwide registry of histopathology and cytopathology (PALGA). For the control cohort 132,654 women with a benign dermal nevus were matched on age and inclusion year with the endometriosis cases. Histological diagnoses of ovarian, fallopian tubes, and peritoneal cancers between January 1990 and July 2017 were retrieved. Incidence rate ratios were estimated for ovarian cancer and its subtypes for the whole follow-up period as well as for women with more than 1 person-year at risk. RESULTS: We found a crude incidence rate ratio of 4.79 (95% confidence interval, 4.33-5.31) and an age-adjusted incidence rate ratio of 7.18 (95% confidence interval, 6.17-8.36) for ovarian cancer overall. Endometrioid and clear-cell ovarian cancer had the highest age-adjusted incidence rate ratio of 29.06 (95% confidence interval, 20.66-40.87) and 21.34 (95% confidence interval, 14.01-32.51), respectively. Median age at ovarian cancer diagnosis was 56 years (interquartile range, 49-63) for the endometriosis cohort and 60 years (interquartile range, 53-67) for the nevus cohort, (P < .05). After excluding women with less than 1 person-year at risk following an endometriosis diagnosis, we found a crude incidence rate ratio of 1.04 (95% confidence interval, 0.91-1.19) and an age-adjusted incidence rate ratio of 1.08 (95% confidence interval, 0.87-1.35) for ovarian cancer overall. However, statistically significant age-adjusted incidence rate ratios of 2.29 (95% confidence interval, 1.24-4.20) for clear-cell ovarian cancer and 2.56 (95% confidence interval, 1.47-4.47) for endometrioid ovarian cancer were found. CONCLUSION: A significantly higher incidence of clear-cell and endometrioid ovarian cancer was found in women with histologically proven endometriosis. Additionally, we found an increased incidence of all ovarian cancer subtypes in histologically proven endometriosis; however, in many of these women, endometriosis and ovarian cancer were diagnosed synchronously after the average menopausal age, which may suggest that the risk of ovarian cancer in endometriosis patients remains, even when clinical endometriosis symptoms are no longer present.

Long-term follow-up after successful Essure sterilization: evaluation of patient satisfaction, symptoms, and the influence of negative publicity.

OBJECTIVE: To evaluate long-term patient satisfaction and symptoms after successful Essure sterilization and the influence of negative publicity on patients' opinion. DESIGN: Survey study. SETTING: Two nonacademic hospitals. PATIENT(S): All 924 women who underwent successful Essure sterilization between 2003 and 2009. INTERVENTION(S): A questionnaire was sent between 2008 and 2010 and in 2018. MAIN OUTCOME MEASURE(S): Patient satisfaction, symptoms, and the influence of negative publicity on patients' opinion of Essure sterilization. RESULT(S): After a median follow-up of 29 months, 689 of 924 women (74.6%) responded to the first questionnaire. Of these women, 673 of 689 (97.7%) was satisfied with their Essure sterilization and 607 of 689 (88.1%) recommended Essure sterilization to other women. Of the 689 women, 71 (10.3%) reported having symptoms after Essure sterilization for which they had to consult a physician. Most reported symptoms were menstrual and abdominal pain. After a median follow-up of 144 months, 317 of 577 women (54.9%) responded to the second questionnaire. A total of 157 of 317 (49.5%) women reported having symptoms and in 51 (16.1%) women the Essure devices were surgically removed. Among these women, 29 (57%) reported that their symptoms disappeared afterward and 33 of 51 (65%) women reported that negative publicity had somehow affected their decision to undergo surgery. CONCLUSION(S): After a follow-up of 144 months, approximately 50% of the women reported having symptoms and 16% underwent Essure removal surgery. Publicity had a negative influence on patients' opinion of Essure sterilization, as well as an effect on the decision-making process regarding Essure removal. These data are important when facing women with possible Essure-related complaints.

Performance of a Haptic Feedback Grasper in Laparoscopic Surgery: A Randomized Pilot Comparison With Conventional Graspers in a Porcine Model.

Background. Compared with open surgery, minimally invasive surgery is limited by reduced sensation of tissue properties. A laparoscopic grasper with integrated haptic feedback technology that improves the ability to sense tissue properties might provide a solution. The force reflecting operation instrument (FROI) is a new laparoscopic grasper, designed to provide information about the interaction forces between the instrument and tissue through resistance in the handle. This pilot study aimed to assess the functionality of the FROI compared with a conventional grasper in an in vivo setting. Methods. In this randomized trial, we used a standard laparoscopic surgical setup to perform laparoscopic surgery in pigs. In all, 11 surgeons performed colorectal, gynecological, or urological procedures, once with the FROI and once with a conventional grasper. Participants were asked to complete the NASA Task Load Index Rating Scale and rate 5 specific features for both graspers. To capture opinions on the overall functionality of the FROI, participants were asked to answer 8 open questions. Results. The surgeons reported that the use of the FROI significantly improved tissue consistency perception, arterial pulse detection, and force control compared with the conventional grasper. No significant differences were found in surgeons' muscular strain or operative time. The most emphasized topics in the open questions were improved soft-tissue handling and importance for complex procedures. Conclusion. Through this first in vivo analysis of the functionality of the FROI, a multispecialty group of laparoscopic surgeons confirmed the added value of haptic feedback technology in a live surgical setting.

Productivity loss due to menstruation-related symptoms: a nationwide cross-sectional survey among 32 748 women.

OBJECTIVE: To evaluate age-dependent productivity loss caused by menstruation-related symptoms, measured in absenteeism (time away from work or school) and presenteeism (productivity loss while present at work or school). METHODS: Design/setting: internet-based, cross-sectional survey conducted in the Netherlands from July to October 2017. PARTICIPANTS: 32 748 women aged 15-45 years, recruited through social media. OUTCOME MEASURES: self-reported lost productivity in days, divided into absenteeism and presenteeism; impact of menstrual symptoms; reasons women give when calling in sick; and women's preferences regarding the implications of menstruation-related symptoms for schools and workplaces. RESULTS: A total of 13.8% (n=4514) of all women reported absenteeism during their menstrual periods with 3.4% (n=1108) reporting absenteeism every or almost every menstrual cycle. The mean absenteeism related to a woman's period was 1.3 days per year. A total of 80.7% (n=26 438) of the respondents reported presenteeism and decreased productivity a mean of 23.2 days per year. An average productivity loss of 33% resulted in a mean of 8.9 days of total lost productivity per year due to presenteeism. Women under 21 years were more likely to report absenteeism due to menstruation-related symptoms (OR 3.3, 95% CI 3.1 to 3.6). When women called in sick due to their periods, only 20.1% (n=908) told their employer or school that their absence was due to menstrual complaints. Notably, 67.7% (n=22 154) of the participants wished they had greater flexibility in their tasks and working hours at work or school during their periods. CONCLUSIONS: Menstruation-related symptoms cause a great deal of lost productivity, and presenteeism is a bigger contributor to this than absenteeism. There is an urgent need for more focus on the impact of these symptoms, especially in women aged under 21 years, for discussions of treatment options with women of all ages and, ideally, more flexibility for women who work or go to school.

Estrogen-Containing Oral Contraceptives Are Associated With Polycystic Liver Disease Severity in Premenopausal Patients.

The association between estrogen-containing oral contraceptives and history of pregnancies with disease severity in women with polycystic liver disease (PLD) is unclear. We performed a cross-sectional cohort study to assess this association by selecting female patients with PLD of which imaging was available prior to any liver volume-reducing therapy. Patients received a questionnaire to collect detailed information on estrogen use and pregnancies. Preplanned subgroup analyses were performed on premenopausal and postmenopausal patients. The questionnaire was returned by 287 of 360 selected patients (80%). There was no significant association between estrogen-containing oral contraceptives and height-adjusted total liver volume (hTLV) in the total group (P = 0.06) and postmenopausal subgroup (P = 0.7). By contrast, each year of exposure corresponds with a 1.45% higher hTLV (P = 0.02) in the premenopausal subgroup, equivalent to a 15.5% higher hTLV for every 10 years of use. Pregnancy duration was not associated with hTLV. In conclusion, patients with PLD should avoid exogenous estrogens.

The impact of menstrual symptoms on everyday life: a survey among 42,879 women.

BACKGROUND: Menstrual symptoms such as dysmenorrhea, heavy menstrual bleeding, and perimenstrual mood disorders are known to be widespread among the general population. From studies in patients with endometriosis and premenstrual disorder, it has been shown that these symptoms can have a large impact on women's quality of life and account for substantial health care use. Furthermore, it is estimated that many women initially do not consult a doctor while facing menstrual symptoms. Consequently, the impact of menstrual symptoms on daily activities in the general population is unknown. OBJECTIVE: To obtain a nationwide overview of menstrual symptoms and their impact on everyday activities. STUDY DESIGN: Nationwide, cross-sectional, internet-based survey among 42,879 women aged 15-45 years, conducted from July to October 2017. OUTCOME MEASURES: presence of menstrual symptoms, pain or intensity score, impact on daily activities. RESULTS: Dysmenorrhea was the most common symptom, with a prevalence of 85%, followed by psychological complaints (77%), and tiredness (71%). During their menstrual period, 38% of all women reported not to be able to perform all their regular daily activities. From the women that had to skip tasks because of their symptoms, only 48.6% told their family that menstrual symptoms were the reason for the transfer of tasks. CONCLUSION: Menstrual symptoms are widespread among the general population. One in 3 women quit daily activities owing to menstrual symptoms. Half of all women did not mention menstrual complaints being the reason for transferring tasks in a family setting. These results must be interpreted with caution owing to the potential for selection bias. However, considering the impact of menstrual symptoms on daily activities in a large group of women, it is time to open the societal dialogue and improve education for both patients and doctors.

Measuring fatigue and stress in laparoscopic surgery: validity and reliability of the star-track test.

BACKGROUND: The star-track test has been assessed as valid and reliable to measure manual dexterity in the context of open surgery. We aimed to determine the construct validity and test-retest reliability of the star-track test for manual dexterity in a laparoscopic setting. MATERIAL AND METHODS: The star-track test was performed in a laparoscopic box trainer. To determine construct validity an open-label, randomized four-period crossover trial was conducted. Alongside a baseline (non-interventional) measurement, interventions involved: physical fatigue, mental stress and a combination of these. The test-retest trial involved two separate (non-interventional) measurements. The primary outcome measures were accuracy, speed and manual dexterity (the integrated measure of accuracy and speed). RESULTS: Participants made significantly more errors when physically fatigued, whereas participants performed the test significantly slower when mentally stressed. Manual dexterity was significantly affected in the case of combined intervention. High test-retest reliability was found for errors (ICC = 0.90) and completion time (ICC = 0.64). Fair test-retest reliability for the integrated measure was found (ICC = 0.37). CONCLUSION: The star-track test is a valid and reliable tool to evaluate the effect of physical fatigue and/or mental stress on the characteristics of manual dexterity in a laparoscopic setting.

Incidence and groups at risk for unexpected uterine leiomyosarcoma: a Dutch nationwide cohort study.

OBJECTIVE: To estimate the risk of uterine leiomyosarcoma in patients undergoing gynecological surgery and also to identify groups at risk for unrecognized uterine leiomyosarcoma. METHODS: A national cohort study was performed evaluating all uterine leiomyosarcoma (ULMS) diagnosed in The Netherlands between January 2000 and September 2015. Cases were identified and supplied by the nationwide network and registry of histo- and cytopathology in The Netherlands (PALGA). Unexpected and expected ULMS were compared. Approval for this study was granted by the Medical Ethics Committee of all participating hospitals and by the review board of PALGA. RESULTS: 262 original cases were included. The overall incidence of ULMS in our study was 0.25% or 1:400 patients. The incidence of unexpected ULMS was 0.12% or 1:865 patients. Preoperatively, a malignancy was unexpected in 46% of the cases and expected in 54%. Abnormal uterine bleeding constituted most of the symptoms. 90% of women underwent abdominal hysterectomy and/or bilateral salpingo-oophorectomy. CONCLUSIONS: Leiomyosarcoma are rare. Women aged 40-50 years with abnormal uterine bleeding are most at risk for unexpected ULMS. In contrast, this risk is low in postmenopausal women. ULMS were highly uncommon in women aged under 40 years.

Noninvasive diagnostic tools for pelvic congestion syndrome: a systematic review.

INTRODUCTION: In the work-up of patients with suspected pelvic congestion syndrome, venography is currently the gold standard. Yet if non-invasive diagnostic tools are found to be accurate, invasive venography might no longer be indicated as necessary. MATERIAL AND METHODS: A literature search in Pubmed and EMBASE was performed from inception until 6 May 2017. Studies comparing non-invasive diagnostic tools to a reference standard in the work-up of patients with (suspected) pelvic congestion syndrome were included. Relevant data were extracted and methodological quality of individual included studies was assessed by the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. RESULTS: Nine studies matched our inclusion criteria. Six studies compared ultrasonography to venography and three studies described a magnetic resonance imaging technique. In using transvaginal ultrasonography, the occurrence of a vein greater than five mm crossing the uterine body had a specificity of 91% (95% CI; 77-98%) and occurrence of pelvic varicoceles a sensitivity and specificity of 100% (95% CI; 89-100%) and 83-100% (95% CI; 66-93%), respectively. In transabdominal ultrasonography, reversed caudal flow in the ovarian vein accounted for a sensitivity of 100% (95% CI; 84-100%). Detection of pelvic congestion syndrome with magnetic resonance imaging techniques resulted in a sensitivity varying from 88 to 100%. CONCLUSIONS: The sensitivity of ultrasonography and magnetic resonance imaging seem to be adequate, which indicates a role for both tests in an early stage of the diagnostic workup. However, due to methodological flaws and diversity in outcome parameters, more high standard research is necessary to establish a clear advice for clinical practice.

Cost-effectiveness of curettage vs. expectant management in women with an incomplete evacuation after misoprostol treatment for first-trimester miscarriage: a randomized controlled trial and cohort study.

INTRODUCTION: Curettage is more effective than expectant management in women with suspected incomplete evacuation after misoprostol treatment for first-trimester miscarriage. The cost-effectiveness of curettage vs. expectant management in this group is unknown. MATERIAL AND METHODS: From June 2012 until July 2014 we conducted a randomized controlled trial and parallel cohort study in the Netherlands, comparing curettage with expectant management in women with an incomplete evacuation of the uterus after misoprostol treatment for first-trimester miscarriage. Successful treatment was defined as a sonographic finding of an empty uterus 6 weeks after study entry, or an uneventful course. Cost-effectiveness and cost-utility analyses were performed. We included costs of healthcare utilization, informal care and lost productivity. Cost-effectiveness planes and cost-effectiveness acceptability curves were estimated using bootstrapping. RESULTS: We included 256 women from 27 hospitals; 95 curettage and 161 expectant management. Treatment was successful in 96% of the women treated with curettage vs. 83% of the women after expectant management (mean difference 13%, 95% confidence interval 5-20). Mean costs were significantly higher in the curettage group (mean difference €1157; 95% C confidence interval €955-1388). The incremental cost-effectiveness ratio for curettage vs. expectant management was €8586 per successfully treated woman. The cost-effectiveness acceptability curve showed that at a willingness-to-pay of €18 200/extra successfully treated women, the probability that curettage is cost-effective is 95%. CONCLUSIONS: Curettage is not cost-effective compared with expectant management in women with an incomplete evacuation of the uterus after misoprostol treatment. This indicates that curettage in this group should be restrained.

The Effect of Screen-to-Screen Versus Face-to-Face Consultation on Doctor-Patient Communication: An Experimental Study with Simulated Patients.

BACKGROUND: Despite the emergence of Web-based patient-provider contact, it is still unclear how the quality of Web-based doctor-patient interactions differs from face-to-face interactions. OBJECTIVE: This study aimed to examine (1) the impact of a consultation medium on doctors' and patients' communicative behavior in terms of information exchange, interpersonal relationship building, and shared decision making and (2) the mediating role of doctors' and patients' communicative behavior on satisfaction with both types of consultation medium. METHODS: Doctor-patient consultations on pelvic organ prolapse were simulated, both in a face-to-face and in a screen-to-screen (video) setting. Twelve medical interns and 6 simulated patients prepared 4 different written scenarios and were randomized to perform a total of 48 consultations. Effects of the consultations were measured by questionnaires that participants filled out directly after the consultation. RESULTS: With respect to patient-related outcomes, satisfaction, perceived information exchange, interpersonal relationship building, and perceived shared decision making showed no significant differences between face-to-face and screen-to-screen consultations. Patients' attitude toward Web-based communication (b=-.249, P=.02 and patients' perceived time and attention (b=.271, P=.03) significantly predicted patients' perceived interpersonal relationship building. Patients' perceived shared decision making was positively related to their satisfaction with the consultation (b=.254, P=.005). Overall, patients experienced significantly greater shared decision making with a female doctor (mean 4.21, SD 0.49) than with a male doctor (mean 3.66 [SD 0.73]; b=.401, P=.009). Doctor-related outcomes showed no significant differences in satisfaction, perceived information exchange, interpersonal relationship building, and perceived shared decision making between the conditions. There was a positive relationship between perceived information exchange and doctors' satisfaction with the consultation (b=.533, P<.001). Furthermore, doctors' perceived interpersonal relationship building was positively related to doctors' satisfaction with the consultation (b=.331, P=.003). CONCLUSIONS: In this study, the quality of doctor-patient communication, as indicated by information exchange, interpersonal relationship building, and shared decision making, did not differ significantly between Web-based and face-to-face consultations. Doctors and simulated patients were equally satisfied with both types of consultation medium, and no differences were found in the manner in which participants perceived communicative behavior during these consultations. The findings suggest that worries about a negative impact of Web-based video consultation on the quality of patient-provider consultations seem unwarranted as they offer the same interaction quality and satisfaction level as regular face-to-face consultations.

The effects of laparoscopic graspers with enhanced haptic feedback on applied forces: a randomized comparison with conventional graspers.

BACKGROUND: Haptic feedback, which enables surgeons to perceive information on interaction forces between instrument and tissue, is deficient in laparoscopic surgery. This information, however, is essential for accurate tissue manipulation and recognition of tissue consistencies. To this end, a laparoscopic grasper with enhanced haptic feedback has been developed: the force reflecting operation instrument (FROI). This study tested the effects of enhanced haptic feedback on force control, tissue consistency interpretation, and the associated surgeons' level of confidence through a randomized controlled crossover experiment. METHODS: A randomized three-period crossover trial was conducted, in which seven surgical residents and 13 medical students participated. The setup involved a box trainer in which slices of porcine organs (lung, small intestine, or liver) were presented. Participants performed three series of blinded palpation tasks involving three different graspers: the conventional grasper, the FROI with enhanced haptic feedback activated, and the FROI with enhanced haptic feedback deactivated. In each series, nine pairs of organ tissues were palpated to compare consistencies. The orders of presenting both instruments and tissues were randomized. RESULTS: The force applied during tissue palpation significantly decreased, by a mean factor of 3.1 with enhanced haptic feedback. Tissue consistency interpretation was significantly improved with more correct assessments and participants answered with significantly more confidence when enhanced haptic feedback was available. CONCLUSION: The availability of enhanced haptic feedback enabled participants to operate with significantly reduced interaction force between instrument and tissues. This observation is expected to have multiple important clinical implications, such as less tissue damage, fewer complications, shorter operation times, and improved ergonomics.

Prevalence of Musculoskeletal Disorders Among Surgeons Performing Minimally Invasive Surgery: A Systematic Review.

OBJECTIVE: The aim of this study was to review musculoskeletal disorder (MSD) prevalence among surgeons performing minimally invasive surgery. BACKGROUND: Advancements in laparoscopic surgery have primarily focused on enhancing patient benefits. However, compared with open surgery, laparoscopic surgery imposes greater ergonomic constraints on surgeons. Recent reports indicate a 73% to 88% prevalence of physical complaints among laparoscopic surgeons, which is greater than in the general working population, supporting the need to address the surgeons' physical health. METHODS: To summarize the prevalence of MSDs among surgeons performing laparoscopic surgery, we performed a systematic review of studies addressing physical ergonomics as a determinant, and reporting MSD prevalence. On April 15 2016, we searched Pubmed, EMBASE, the Cochrane Library, Web of Science, CINAHL, and PsychINFO. Meta-analyses were performed using the Hartung-Knapp-Sidik-Jonkman method. RESULTS: We identified 35 articles, including 7112 respondents. The weighted average prevalence of complaints was 74% [95% confidence interval (95% CI) 65-83]. We found high inconsistency across study results (I = 98.3%) and the overall response rate was low. If all nonresponders were without complaints, the prevalence would be 22% (95% CI 16-30). CONCLUSIONS: From the available literature, we found a 74% prevalence of physical complaints among laparoscopic surgeons. However, the low response rates and the high inconsistency across studies leave some uncertainty, suggesting an actual prevalence of between 22% and 74%. Fatigue and MSDs impact psychomotor performance; therefore, these results warrant further investigation. Continuous changes are enacted to increase patient safety and surgical care quality, and should also include efforts to improve surgeons' well-being.

Ergonomics of laparoscopic graspers and the importance of haptic feedback: the surgeons' perspective.

Haptic feedback is drastically reduced in laparoscopic surgery compared to open surgery. Introducing enhanced haptic feedback in laparoscopic instruments might well improve surgical safety and efficiency. In the design process of a laparoscopic grasper with enhanced haptic feedback, handle design should be addressed to strive for optimal usability and comfort. Additionally, the surgeons' perspective on the potential benefits of haptic feedback should be assessed to ascertain the clinical interest of enhanced haptic feedback. A questionnaire was designed to determine surgeons' use and preferences for laparoscopic instruments and expectations about enhanced haptic feedback. Surgeons were also asked whether they experience physical complaints related to laparoscopic instruments. The questionnaire was distributed to a group of laparoscopic surgeons based in Europe. From the 279 contacted subjects, 98 completed the questionnaire (response rate 35 %). Of all respondents, 77 % reported physical complaints directly attributable to the use of laparoscopic instruments. No evident similarity in the main preference for graspers was found, either with or without haptic feedback. According to respondents, the added value of haptic feedback could be of particular use in feeling differences in tissue consistencies, feeling the applied pressure, locating a tumor or enlarged lymph node, feeling arterial pulse, and limiting strain in the surgeon's hand. This study stresses that the high prevalence of physical complaints directly related to laparoscopic instruments among laparoscopic surgeons is still relevant. Furthermore, the potential benefits of enhanced haptic feedback in laparoscopic surgery are recognized by laparoscopic specialists. Therefore, haptic feedback is considered an unmet need in laparoscopy.

Atypical Endometrial Polyps and Concurrent Endometrial Cancer: A Systematic Review.

OBJECTIVE: To estimate the risk of concurrent endometrial cancer in nonpolypoid endometrium when atypia was diagnosed within an endometrial polyp. DATA SOURCES: MEDLINE, EMBASE, Web of Science, and ClinicalTrials.gov were searched for studies published between 1990 and January 2015 in which 1) women with atypical hyperplastic endometrial polyps underwent a consecutive hysterectomy; or 2) the natural behavior of endometrium with concurrent atypical endometrial polyps was evaluated. METHODS OF STUDY SELECTION: Studies were selected when at least one patient within each study was initially diagnosed with an atypical endometrial polyp for which follow-up pathology was available. RESULTS: Broad searches yielded 2,922 authentic citations, 307 met criteria for full-text evaluation, and 10 met inclusion criteria. Two authors independently reviewed articles and consensus was reached. The final selection included eight retrospective studies reporting on concurrent endometrial cancer in case of atypical endometrial polyps and two follow-up studies on patients conserving their uterus after hysteroscopic resection of atypical endometrial polyps. In total, 127 patients were included with an initial diagnosis of atypical endometrial hyperplasia within polyps. Meta-analysis showed a pooled risk estimate of 5.6% (95% confidence interval [CI] 0.2-17.6%) on concurrent endometrial cancer after resection of an atypical endometrial polyp. CONCLUSION: The pooled risk estimate of 5.6% (95% CI 0.2-17.6%) on endometrial cancer when atypia is found within an endometrial polyp differs from the well-established risk of nonpolypoid atypical endometrial hyperplasia on endometrial cancer of up to 42%. This risk of endometrial cancer is important in the process of shared decision-making regarding follow-up and further treatment.
