The effect of surgery or medication on pain and quality of life in women with endometrioma. A systematic review and meta-analysis

For patients with endometrioma it is unclear what treatment: surgery and/or medication, is more effective in reducing pain and improving quality of life (QoL). This systematic review and meta- analysis aimed to provide an overview of the existing evidence on the effects of surgery and/or medication (i.e. analgesics and/or hormonal medication) on pain and QoL. A search through CENTRAL, MEDLINE and Embase was conducted. The study population had to be women treated for endometrioma. Retrospective or prospective studies reporting about QoL and/or the following types of pain were reviewed: dysmenorrhea, dyspareunia, chronic pelvic pain, and pain that was not well defined in the included article (referred to as pain). We performed a meta-analysis on mean visual analogue scale (VAS) scores and proportions of patients experiencing different types of pain over time. QoL was described narratively. Out of 11.515 articles, 76 studies including 7148 patients were included for the systematic review. The meta-analysis consisted of 52 studies including 4556 patients. No studies compared medication with surgery. And there were no studies on analgesics. Meta-analysis showed that surgery and/or medication often reduced VAS scores and proportions of all types of pain over time. Surgery and medication combined seems more effective in reducing VAS scores of pain compared to surgery alone, but not to medication alone (estimated mean difference = 0.17, p < 0.0001 and -0.98, p = 0.0339). QoL improved after medication (follow up ≤ 12 months) and QoL was unchanged or worsened after surgery and medication combined (follow up ≤ 24 months). However, these were results from a total of 5 studies. Both surgery and medication reduce endometriosis-related pain in patients with endometrioma. However, there is lack of uniform, good quality data comparing surgery with medication to draw firm conclusions. For better-informed treatment decisions, further studies including a standardized core-outcome set at fixed follow-up times, are necessary.

Psychological impact over time of women with pregnancy loss due to gestational trophoblastic disease compared with miscarriage

OBJECTIVES

Pregnancy loss, occurring after miscarriage or after gestational trophoblastic disease, has a psychological impact. Besides pregnancy loss, women diagnosed with gestational trophoblastic disease have to deal with a prolonged period of follow-up and potential advice to postpone a future pregnancy. We studied the severity and course of the psychological impact after gestational trophoblastic disease and miscarriage, to identify whether women with gestational trophoblastic disease need different psychological care.

METHODS

A prospective multicenter study using online questionnaires was performed. Women diagnosed with gestational trophoblastic disease or miscarriage received the following questionnaires directly after diagnosis, and after 6, 6, and 12 months: a self-report questionnaire, the Hospital Anxiety and Depression Scale (HADS), the Impact of Event Scale, and the Reproductive Concerns Scale.

RESULTS

74 women with gestational trophoblastic disease and 76 women with miscarriage were included. At baseline, the proportion of women scoring above the cut-off level for the anxiety subscale of the HADS and for the Impact of Event Scale was significantly higher for women with gestational trophoblastic disease than for women after miscarriage (43.2% vs 28.9%, p=0.02 and 87.8% vs 78.9%, p=0.03, respectively). During follow-up, the differences between both groups vanished and only the Impact of Event Scale after 12 months remained significantly different between women with gestational trophoblastic disease and women after miscarriage (62.7% vs 37.3%, p=0.005). All outcomes, except the Reproductive Concerns Scale, showed a significant decline. However, in women who scored above the cut-off level on the HADS-total or Impact of Event Scale at baseline, and women with psychological or psychiatric history, significant higher scores persisted.

CONCLUSION

Although women with gestational trophoblastic disease at baseline had more anxiety and distress than women after miscarriage, no significant differences were seen using the HADS-total after 12 months. Using the HADS or Impact of Event Scale directly after pregnancy loss is helpful to identify women at risk of remaining psychological symptoms to provide them with extra psychological support.

Predicting the likelihood of successful medical treatment of early pregnancy loss: development and internal validation of a clinical prediction model

STUDY QUESTION

What are clinical predictors for successful medical treatment in case of early pregnancy loss (EPL)?

SUMMARY ANSWER

Use of mifepristone, BMI, number of previous uterine aspirations and the presence of minor clinical symptoms (slight vaginal bleeding or some abdominal cramps) at treatment start are predictors for successful medical treatment in case of EPL.

WHAT IS KNOWN ALREADY

Success rates of medical treatment for EPL vary strongly, between but also within different treatment regimens. Up until now, although some predictors have been identified, no clinical prediction model has been developed yet.

STUDY DESIGN, SIZE, DURATION

Secondary analysis of a multicentre randomized controlled trial in 17 Dutch hospitals, executed between 28 June 2018 and 8 January 2020.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Women with a non-viable pregnancy between 6 and 14 weeks of gestational age, who opted for medical treatment after a minimum of 1 week of unsuccessful expectant management. Potential predictors for successful medical treatment of EPL were chosen based on literature and expert opinions. We internally validated the prediction model using bootstrapping techniques.

MAIN RESULTS AND THE ROLE OF CHANCE

237 out of 344 women had a successful medical EPL treatment (68.9%). The model includes the following variables: use of mifepristone, BMI, number of previous uterine aspirations and the presence of minor clinical symptoms (slight vaginal bleeding or some abdominal cramps) at treatment start. The model shows a moderate capacity to discriminate between success and failure of treatment, with an AUC of 67.6% (95% CI = 64.9-70.3%). The model had a good fit comparing predicted to observed probabilities of success but might underestimate treatment success in women with a predicted probability of success of ∼70%.

LIMITATIONS, REASONS FOR CAUTION

The vast majority (90.4%) of women were Caucasian, potentially leading to less optimal model performance in a non-Caucasian population. Limitations of our model are that we have not yet been able to externally validate its performance and clinical impact, and the moderate accuracy of the prediction model of 0.67.

WIDER IMPLICATIONS OF THE FINDINGS

We developed a prediction model, aimed to improve and personalize counselling for medical treatment of EPL by providing a woman with her individual chance of complete evacuation.

Single- versus double-layer closure of the caesarean (uterine) scar in the prevention of gynaecological symptoms in relation to niche development - the 2Close study: a multicentre randomised controlled trial

BACKGROUND

Double-layer compared to single-layer closure of the uterus after a caesarean section (CS) leads to a thicker myometrial layer at the site of the CS scar, also called residual myometrium thickness (RMT). It possibly decreases the development of a niche, which is an interruption of the myometrium at the site of the uterine scar. Thin RMT and a niche are associated with gynaecological symptoms, obstetric complications in a subsequent pregnancy and delivery and possibly with subfertility.

METHODS

Women undergoing a first CS regardless of the gestational age will be asked to participate in this multicentre, double blinded randomised controlled trial (RCT). They will be randomised to single-layer closure or double-layer closure of the uterine incision. Single-layer closure (control group) is performed with a continuous running, unlocked suture, with or without endometrial saving technique. Double-layer closure (intervention group) is performed with the first layer in a continuous unlocked suture including the endometrial layer and the second layer is also continuous unlocked and imbricates the first. The primary outcome is the reported number of days with postmenstrual spotting during one menstrual cycle nine months after CS. Secondary outcomes include surgical data, ultrasound evaluation at three months, menstrual pattern, dysmenorrhea, quality of life, and sexual function at nine months. Structured transvaginal ultrasound (TVUS) evaluation is performed to assess the uterine scar and if necessary saline infusion sonohysterography (SIS) or gel instillation sonohysterography (GIS) will be added to the examination. Women and ultrasound examiners will be blinded for allocation. Reproductive outcomes at three years follow-up including fertility, mode of delivery and complications in subsequent deliveries will be studied as well. Analyses will be performed by intention to treat. 2290 women have to be randomised to show a reduction of 15% in the mean number of spotting days. Additionally, a cost-effectiveness analysis will be performed from a societal perspective.

DISCUSSION

This RCT will provide insight in the outcomes of single- compared to double-layer closure technique after CS, including postmenstrual spotting and subfertility in relation to niche development measured by ultrasound.

The value of fine needle aspiration cytology diagnosis in ovarian masses in children and adolescents

STUDY QUESTION

Is ovarian cytology a reliable predictor for a malignant ovarian mass?

SUMMARY ANSWER

Cytology of an ovarian mass in children and adolescents cannot be used to exclude malignancy.

WHAT IS KNOWN ALREADY

It is hard to predict malignancy in case of an ovarian mass in a child or adolescent. The most common reason to perform fine needle aspiration cytology (FNAC) is to exclude malignancy. Ovarian cytology has shown varying results in adults, but test performance in a younger population is unknown.

STUDY DESIGN, SIZE, DURATION

This was a retrospective diagnostic test accuracy study. We used a nationwide registry, the PALGA database, to select girls aged 18 or younger with matching ovarian cytology and histology reports available between 1990 and 2014.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Histology diagnoses were classified according to the WHO classification of ovarian pathology. Cytology diagnoses were classified as benign, borderline malignant or malignant. Cases with inconclusive cytology diagnoses were excluded from the analysis of diagnostic accuracy. Diagnostic accuracy was calculated using a 2 × 2 table.

MAIN RESULTS AND THE ROLE OF CHANCE

Included were 552 girls under the age of 18 who had a cytology and a histology report of the same ovary available in the PALGA database. In 523 (94.7%) patients the mass was benign; 19 (3.4%) patients had a borderline malignancy and 9 (1.7%) patients had a malignant tumour. The histology diagnosis was unknown in one patient due to torsion of the ovary. Cytological diagnosis was inconclusive in 96 patients (17.4%). Cytology had a sensitivity of 32.0% and a specificity of 99.8%. Post-test probability of malignancy with positive cytology was 88.9%; the post-test probability of a malignancy with negative cytology was 3.8%, compared with a pre-test probability of 5.5%.

LIMITATIONS, REASONS FOR CAUTION

This study was retrospective, using data gathered over 24 years. Cytology was retrieved during surgery or at the pathology department in 86.6% of the cases and pathologists were not blinded, which can be a cause for bias.

WIDER IMPLICATIONS OF THE FINDINGS

Since the sensitivity is low, FNAC is not a recommended diagnostic tool in children. The post-test probability of a negative test compared with the incidence in our population resulted in a minimal difference not worth an invasive procedure.

Are patient characteristics associated with the accuracy of hysterosalpingography in diagnosing tubal pathology? An individual patient data meta-analysis

BACKGROUND

Conventional meta-analysis has estimated the sensitivity and specificity of hysterosalpingography (HSG) to be 65% and 83%. The impact of patient characteristics on the accuracy of HSG is unknown. The aim of this study was to assess by individual patient data meta-analysis whether the accuracy of HSG is associated with different patient characteristics.

METHODS

We approached authors of primary studies reporting on the accuracy of HSG using findings at laparoscopy as the reference. We assessed whether patient characteristics such as female age, duration of subfertility and a clinical history without risk factors for tubal pathology were associated with the accuracy of HSG, using a random intercept logistic regression model.

RESULTS

We acquired data of seven primary studies containing data of 4521 women. Pooled sensitivity and specificity of HSG were 53% and 87% for any tubal pathology and 46% and 95% for bilateral tubal pathology. In women without risk factors, the sensitivity of HSG was 38% for any tubal pathology, compared with 61% in women with risk factors (P = 0.005). For bilateral tubal pathology, these rates were 13% versus 47% (P = 0.01). For bilateral tubal pathology, the sensitivity of HSG decreased with age [factor 0.93 per year (P = 0.05)]. The specificity of HSG was very stable across all subgroups.

CONCLUSIONS

The accuracy of HSG in detecting tubal pathology was similar in all subgroups, except for women without risk factors in whom sensitivity was lower, possibly due to false-positive results at laparoscopy. HSG is a useful tubal patency screening test for all infertile couples.

The value of medical history taking as risk indicator for tuboperitoneal pathology: a systematic review

BACKGROUND

Guidelines recommend diagnostic laparoscopy in subfertile women with known co-morbidities in their medical history. Aggregated evidence underpinning these recommendations is, however, currently lacking.

OBJECTIVE

The objective of this study was to perform a systematic review and meta-analysis of the available evidence on the association between items reported during medical history taking and tuboperitoneal pathology.

SEARCH STRATEGY

MEDLINE (from 1966 to May 2007), EMBASE (from 1960 to January 2007) and bibliographies of retrieved primary articles.

SELECTION CRITERIA

All relevant studies that compared medical history with the presence or absence of tubal pathology.

DATA COLLECTION AND ANALYSIS

Studies comparing medical history with the presence or absence of tubal pathology were included. A diagnosis of tubal pathology had to be made by hysterosalpingography, laparoscopy or a combination of both. In the absence of invasive tubal testing, tuboperitoneal pathology was considered to be absent in case of intrauterine pregnancy. Homogeneity between studies was assessed, and the association between medical history and tubal pathology was expressed as a common odds ratio with a 95% CI. No language restriction was applied.

MAIN RESULTS

We included 32 studies. In cohort studies, strong associations were found for a history of complicated appendicitis (OR 7.2, 95% CI 2.2-22.8), pelvic surgery (OR 3.6, 95% CI 1.4-9.0) and pelvic inflammatory disease (PID) (OR 3.2, 95% CI 1.6-6.6), and in case-control studies, for a history of complicated appendicitis (OR 3.3, 95% CI 1.8-6.3), PID (OR 5.5, 95% CI 2.7-11.0), ectopic pregnancy (OR 16.0, 95% CI 12.5-20.4), endometriosis (OR 5.9, 95% CI 3.2-10.8) and sexually transmitted disease (OR 11.9, 95% CI 4.3-33.3).

AUTHOR'S CONCLUSIONS

Subfertile women reporting a history of PID, complicated appendicitis, pelvic surgery, ectopic pregnancy and endometriosis are at increased risk of having tuboperitoneal pathology. In these women, diagnostic laparoscopy should be offered early in the fertility work-up.

Identifying subfertile ovulatory women for timely tubal patency testing: a clinical decision rule based on medical history

BACKGROUND

The aim of tubal testing is to identify women with bilateral tubal pathology in a timely manner, so they can be treated with IVF or tubal surgery. At present, it is unclear for which women early tubal testing is indicated, and in whom it can be deferred.

METHODS

Data on 3716 women who underwent tubal patency testing as a part of their routine fertility workup were used to relate elements in their medical history to the presence of tubal pathology. With multivariable logistic regression, we constructed two diagnostic models. One in which tubal disease was defined as occlusion and/or severe adhesions of at least one tube, whereas in a second model, tubal disease was defined as the presence of bilateral abnormalities.

RESULTS

Both models discriminated moderately well between women with and women without tubal disease with an area under the receiver-operating characteristic curve (AUC) of 0.65 (95% CI: 0.63-0.68) for any tubal pathology and 0.68 (95% CI: 0.65-0.71) for bilateral tubal pathology, respectively. However, the models could make an almost perfect distinction between women with a high and a low probability of tubal pathology. A decision rule in the form of a simple diagnostic score chart was developed for application of the models in clinical practice.

CONCLUSIONS

In conclusion, the present study provides two easy to use decision rules that can accurately express a woman's probability of (severe) tubal pathology at the couple's first consultation. They could be used to select women for tubal testing more efficiently.

[An underestimated technique for the management of shoulder dystocia: the all-fours manoeuvre]

In two pregnant women, parturition was complicated by severe shoulder dystocia. Conventional techniques for the management of this complication of labour failed. By means of the all-fours manoeuvre in combination with conventional techniques it was possible to deliver the babies. Both mothers had received epidural anaesthesia, which did not cause any difficulty during the use of the all-fours procedure. Both newborn infants had low 1-minute Apgar scores and suffered from a brachial-plexus injury. No major maternal morbidity was associated with the use of this procedure. These cases emphasize the importance of keeping obstetrical ward personnel well-trained with multidisciplinary simulation sessions, as well as the importance of proper documentation of the management of this complication.

The predictive value of medical history taking and Chlamydia IgG ELISA antibody testing (CAT) in the selection of subfertile women for diagnostic laparoscopy: a clinical prediction model approach

BACKGROUND

Medical history taking as well as Chlamydia antibody titre (CAT) testing are currently used in the selection of patients for diagnostic laparoscopy with tubal patency testing. Most research has focused on the predictive value of CAT in isolation from medical history. We assessed therefore whether the combination of medical history and CAT improves the efficiency of selecting patients for laparoscopy as compared to the use of either medical history or CAT.

METHODS

Data of 207 consecutive subfertile women were used to create multivariable logistic regression models for the prediction of tubal disease as diagnosed by diagnostic laparoscopy.

RESULTS

The model with data of medical history only had an area under the receiver operating characteristic curve (AUC) of 0.65 (95% CI 0.56-0.74). Addition of CAT increased the AUC to 0.70 (95% CI 0.62-0.78) (P = 0.065). CAT was positive in 40 women and showed a sensitivity of 0.37 (95% CI 0.26-0.49) for a specificity of 0.88 (95% CI 0.82-0.93). In CAT positive women, a blank medical history did not decrease the probability of tubal disease. Of the 167 women tested CAT negative, 23 (14%) still had a high probability of disease due to their medical history and 11 of them (48%) showed tubal abnormalities on diagnostic laparoscopy.

CONCLUSIONS

CAT testing adds valuable information to a woman's risk profile based on her medical history. The combination of medical history taking and CAT testing has a better yield for diagnosing tubal disease than either of these alone.
