Endometriosis: the role of magnetic resonance imaging

Several imaging options are available today to diagnose endometriosis. Currently, the two techniques most used are sonography and magnetic resonance imaging (MRI). Three-dimensional (3D) sonography has proved to be particularly sensitive in the diagnosis of endometriosis. In recent years, MRI has emerged as a high reproducible method to explore endometriosis; moreover, its capability to evaluate tissue signal is an extremely powerful system in the differential diagnosis with other pathologies and for the identification of malignant degeneration. The purpose of this paper is to present the state-of-the-art of MRI of endometriosis by performing a review of the literature and showing the epidemiology, pathogenesis, and classification of endometriosis. In this work, the technique that should be used, MR findings of endometriosis and the principles of differential diagnosis are explained.

Focusing on surgery results in infertile patients with deep endometriosis

Infertility is a common problem in patients with endometriosis and the involved mechanisms are still not completely known. The management of infertility in endometriosis patients includes surgery as well as assisted reproductive technology. Laparoscopic surgery has shown better results in infertility patients with endometriosis in comparison to laparotomy procedures. Laparoscopic surgery has proposed benefits in both minimal to moderate diseases. However, while there may be some benefits with severe diseases, there is still not enough evidence to recommend laparoscopic surgery as the recommended surgery when the main goal is to obtain fertility. We performed a MEDLINE search for articles on fertility in women with deep infiltrating endometriosis (DIE) published between 1990 and April 2015 using the following keywords: "endometriosis", "deep infiltrative endometriosis", "infertility", "fertility after surgery", "laparoscopy surgery", "laparotomy", "pregnancy", "fertility outcome", "bladder endometriosis", and "ureteral endometriosis". The aim of this review was to analyze the results of available clinical studies (randomized controlled or not controlled studies; retrospective cohort studies; or case-control and prospective studies) and guidelines on surgical treatment of infertile endometriosis patients, and pregnancy outcomes after surgery.

Reproducibility of two different methods for performing mean gray value evaluation of cyst content in endometriomas using VOCAL

OBJECTIVE

To compare two different methods (manual sampling of the entire cyst and semi-automated spherical sampling from the central part of the cyst) for calculating the mean gray value (MGV) from the cystic content in endometriomas using virtual organ computer-aided analysis (VOCAL).

METHODS

Forty-one volumes from histologically confirmed endometriomas were retrieved from our database and the volumes were analyzed to compare the MGVs obtained via the two modalities. In addition, to evaluate the reproducibility in a sample of 20 volumes, two different observers calculated the MGV from cyst content using VOCAL software. For each method, each examiner analyzed the volumes twice, 3 weeks apart, for assessment of intra-observer agreement. First, manual sampling of the internal contour of all the cysts was performed, and 1 week later semi-automated 2-cm sphere sampling from the central part of the cyst was carried out. In addition, the observers recorded the time spent performing each analysis. Inter- and intra-observer reproducibility was evaluated for each method using intra-class correlation coefficients (ICC).

RESULTS

There was no difference in the mean MGV between manual sampling (22.211 ± 7.541) and the semi-automated modality of sampling (23.840 ± 8.621, p = 0.439). The correlation between manual and semi-automated sampling measurement was high (r = 0.92). According to the ICCs, there was no significant difference in interobserver reliability between manual sampling (0.931; 95 % CI, 0.824-0.973) and the semi-automated modality of sampling (0.924; 95 % CI, 0.809-0.970). Intra-observer reproducibility for both examiners was good (ICC > 0.94). Semi-automated measurements were obtained faster than those obtained by manual evaluation (p = 0.0001 for observer 1 and p = 0.083 for observer 2).

CONCLUSIONS

Both methods seem to be reliable, but the semi-automated method using the sphere should be preferred because it is a less time-consuming procedure.

Observational study on the efficacy of the supplementation with a preparation with several minerals and vitamins in improving mood and behaviour of healthy puerperal women

We investigated whether a formulation containing vitamins and minerals (vit&min) could improve the worsening of mood changes occurring after delivery ("a.d."). The study was performed in 552 healthy non-anaemic puerperal women ("p.w") without risk factors for puerperal depression ("p.d"). They were at their first full-term pregnancy, and spontaneously delivered healthy newborns. The Edinburgh Depression Postnatal scale (EPDS) evaluates the psychological status of "p.w". EPDS was administered the 3rd (visit 1), 15th (visit 2) and 30th (visit 3) day "a.d.". An EPDS >12 indicates a major susceptibility to "p.d". At the same time intervals, haemoglobin, iron and ferritin (haematological parameters) levels were evaluated. After visit 1, the subjects were randomized to vit&min treatment (group A; N.274) or to calcium/vitamin D3 treatment (group B; N.278). In both groups haematological parameters significantly increased without differences between the groups. EPDS score improved in both groups, but in the group A, the EPDS decrease was significantly larger (p < 0.05) in comparison to the group B. This effect is mainly evident in subjects with a basal EPDS ≥ 12. An early examination of psychological condition could select "p.w." with a high susceptibility to neuronal changes occurring postpartum. Vit&min favourably modulates brain functions antagonizing the evolution to "p.d".

Tissue characterization using mean gray value analysis in deep infiltrating endometriosis

OBJECTIVES

To investigate differences in tissue characterization using three-dimensional sonographic mean gray value (MGV) between retrocervical and rectosigmoid deeply infiltrating endometriosis, and to assess intra- and interobserver concordance in MGV quantification.

METHODS

In this retrospective study, stored ultrasound volumes from 50 premenopausal women (mean age, 32 years) with 57 histologically confirmed nodules of deep endometriosis were retrieved from our database for analysis. A single experienced operator had acquired all volumes. For each nodule, the MGV was evaluated using virtual organ computer-aided analysis (VOCAL) software with semiautomated sphere-sampling (1 cm3) from the central part of the nodule. In these patients the MGV was also quantified from the myometrium of the fundal part of the uterus. In addition, two observers calculated the MGV in a subset of 24 volumes in order to quantify inter- and intraobserver agreement using intraclass correlation coefficients (ICC).

RESULTS

Mean MGV was significantly higher in rectosigmoid nodules (n = 34) than in nodules with a retrocervical location (n = 23) (23.863 vs. 17.705; P < 0.001). MGV of the myometrium was significantly higher in comparison with that of nodules in both locations (P < 0.001 for both). Intra- and interobserver measurement reproducibility was excellent (ICC > 0.95).

CONCLUSIONS

Retrocervical and rectosigmoid endometriotic nodules display significantly different MGVs. Measurement of MGV is highly reproducible and its clinical value in the diagnosis and assessment of distribution of deep endometriosis should be assessed in future studies.

Role of imaging in the management of endometriosis

The imaging techniques have a fundamental role in the diagnosis of endometriosis. Ovarian endometriosis (endometrioma) and deep endometriosis can be recognized using transvaginal ultrasound and/or magnetic resonance imaging (MRI). Although transvaginal ultrasound is the first choice of imaging modality when investigating women with pelvic pain, MRI have a role for the wider field of visions. The reproducibility of both techniques has been investigated. The three-dimensional ultrasonography has been proposed. Also studies regarding unusual localizations are reported in the literature. New insights are present about the role of imaging in the detection of the malignant transformations. This review summarizes the current evidence on the diagnostic accuracy of these two techniques in the pre-surgical assessment of endometriosis.

Efficacy and tolerability of a monophasic combined oral contraceptive containing nomegestrol acetate and 17β-oestradiol in a 24/4 regimen, in comparison to an oral contraceptive containing ethinylestradiol and drospirenone in a 21/7 regimen

OBJECTIVES

The primary objective was to assess the efficacy, cycle control and tolerability of a monophasic combined oral contraceptive (COC) containing nomegestrol acetate (NOMAC) and 17β-oestradiol (E2). Effects on acne were evaluated as a secondary objective. Results were compared to those of a COC containing drospirenone (DRSP) and ethinylestradiol (EE).

METHODS

Women (aged 18-50 years) were randomised to receive NOMAC/E2 (2.5 mg/1.5 mg) in a 24/4-day regimen (n=1591) or DRSP/EE (3 mg/30 μg) in a 21/7-day regimen (n=535) for 13 cycles.

RESULTS

Estimated Pearl Indices for NOMAC/E2 and DRSP/EE were 0.38 and 0.81 in women aged≤35 years and 0.31 and 0.66 for all women (18-50 years), respectively. Scheduled withdrawal bleedings were shorter and lighter among users of NOMAC/E2 and were sometimes absent altogether. Intracyclic bleeding/spotting was infrequent in both groups, and decreased over time. Type and frequency of adverse events were similar to those typically reported for COCs.

CONCLUSIONS

These data show that NOMAC/E2 provides high contraceptive efficacy with acceptable cycle control as well as an overall adverse event profile similar to that of DRSP/EE.

The quantitative insulin sensitivity check index is not able to detect early metabolic alterations in young patients with polycystic ovarian syndrome

OBJECTIVE

To verify whether QUICKY is a suitable method for the identification of metabolic deterioration in normal weight patients affected by polycystic ovarian syndrome (PCOS).

DESIGN

Prospective clinical study.

PATIENT(S)

Seventy-nine PCOS normal weight adolescent subjects, 50 eumenorrheic, normal weight, non-hirsute controls matched for age and BMI.

METHOD(S)

Quantitative insulin sensitivity check index (QUICKY) and integrated secretory area under the curve of insulin values (I-AUC) during oral glucose tolerance test were calculated.

RESULT(S)

Seventy-nine PCOS and 50 controls were studied. Normal insulin sensitivity was defined as upper control 95th percentile by QUICKY values <0.31, I-AUC at 180 min < 16,645. When applying the calculated I-AUC cut-off, 41 PCOS were classified as normoinsulinemic and 38 as hyperinsulinemic, whereas using the calculated QUICKY cut-off, only 19 PCOS could be classified as insulin resistant (IR). Fifteen out of the 60 non-IR PCOS presented hyperinsulinemia; fasting glucose and insulin levels and QUICKY were not sufficient to identify these subjects. Thus, QUICKY displayed a low sensitivity (44%) and specificity (91%) in the diagnosis of the metabolic disorder disclosed by I-AUC. CONCLUSIONS.: In young normal weight patients with PCOS the prevalence of early alterations of insulin metabolism are not detectable by QUICKY studies.

[Prevention of postoperative abdominal adhesions in gynecological surgery. Consensus paper of an Italian gynecologists' task force on adhesions]

Adhesions are the most frequent complication of abdominopelvic surgery, causing important short- and long-term problems, including infertility, chronic pelvic pain and a lifetime risk of small bowel obstruction. They also complicate future surgery with considerable morbidity and expense, and an important mortality risk. They pose serious quality of life issues for many patients with associated social and healthcare costs. Despite advances in surgical techniques, the healthcare burden of adhesion-related complications has not changed in recent years. Adhesiolysis remains the main treatment although adhesions reform in most patients. There is rising evidence, however, that surgeons can take important steps to reduce the impact of adhesions. A task force of Italian gynecologists with a specialist interest in adhesions having reviewed the current evidence on adhesions and considered the opportunities to reduce adhesions in Italy, have approved a collective consensus position. This consensus paper provides a comprehensive overview of adhesions and their consequences and practical proposals for actions that gynecological surgeons in Italy should take. As well as improvements in surgical technique, developments in adhesion-reduction strategies and new agents offer a realistic possibility of reducing adhesion formation and improving outcomes for patients. They should be adopted particularly in high risk surgery and in patients with adhesiogenic conditions. Patients also need to be better informed of the risks of adhesions.

The diagnosis of ovarian cancer: is color Doppler imaging reproducible and accurate in examiners with different degrees of experience?

OBJECTIVE

To evaluate the reproducibility and accuracy of color Doppler flow location in indeterminate masses after a gray-scale sonography in the diagnosis of ovarian malignancy.

METHODS

Digitally stored color Doppler sonographic images from a random sample of 130 women with an indeterminate adnexal mass submitted to surgery were evaluated by six different examiners with different degrees of experience. A mass was graded malignant if flow was shown within the excrescences or solid areas. Intraobserver agreement and interobserver agreement according to the level of experience were assessed by calculating the kappa index.

RESULTS

Intraobserver agreement was good for all examiners with different degrees of experience (kappa 0.72-0.89). Interobserver agreement was good to moderate for all operators (kappa 0.48-0.71) irrespective of degree of experience. The accuracy was comparable among different operators.

CONCLUSIONS

Our results indicate that color Doppler imaging for detection of adnexal malignancy seems to be a reproducible method even in moderately experienced examiners.

Improving the preoperative classification of adnexal masses as benign or malignant by second-stage tests

OBJECTIVE

The aim of this study was to establish when a second-stage diagnostic test may be of value in cases where a primary diagnostic test has given an uncertain diagnosis of the benign or malignant nature of an adnexal mass.

METHODS

The diagnostic performance with regard to discrimination between benign and malignant adnexal masses for mathematical models including ultrasound variables and for subjective evaluation of ultrasound findings by an experienced ultrasound examiner was expressed as area under the receiver-operating characteristics curve (AUC), sensitivity and specificity. These were calculated for the total study population of 1938 patients with an adnexal mass as well as for subpopulations defined by the certainty with which the diagnosis of benignity or malignancy was made. The effect of applying a second-stage test to the tumors where risk estimation was uncertain was determined.

RESULTS

The best mathematical model (LR1) had an AUC of 0.95, sensitivity of 92% and specificity of 84% when applied to all tumors. When model LR1 was applied to the 10% of tumors in which the calculated risk fell closest to the risk cut-off of the model, the AUC was 0.59, sensitivity 90% and specificity 21%. A strategy where subjective evaluation was used to classify these 10% of tumors for which LR1 performed poorly and where LR1 was used in the other 90% of tumors resulted in a sensitivity of 91% and specificity of 90%. Applying subjective evaluation to all tumors yielded an AUC of 0.95, sensitivity of 90% and specificity of 93%. Sensitivity was 81% and specificity 47% for those patients where the ultrasound examiner was uncertain about the diagnosis (n = 115; 5.9%). No mathematical model performed better than did subjective evaluation among the 115 tumors where the ultrasound examiner was uncertain.

CONCLUSION

When model LR1 is used as a primary test for discriminating between benign and malignant adnexal masses, the use of subjective evaluation of ultrasound findings by an experienced examiner as a second-stage test in the 10% of cases for which the model yields a risk of malignancy closest to its risk cut-off will improve specificity without substantially decreasing sensitivity. However, none of the models tested proved suitable as a second-stage test in tumors where subjective evaluation yielded an uncertain result.

Simple ultrasound rules to distinguish between benign and malignant adnexal masses before surgery: prospective validation by IOTA group

OBJECTIVES

To prospectively assess the diagnostic performance of simple ultrasound rules to predict benignity/malignancy in an adnexal mass and to test the performance of the risk of malignancy index, two logistic regression models, and subjective assessment of ultrasonic findings by an experienced ultrasound examiner in adnexal masses for which the simple rules yield an inconclusive result.

DESIGN

Prospective temporal and external validation of simple ultrasound rules to distinguish benign from malignant adnexal masses. The rules comprised five ultrasonic features (including shape, size, solidity, and results of colour Doppler examination) to predict a malignant tumour (M features) and five to predict a benign tumour (B features). If one or more M features were present in the absence of a B feature, the mass was classified as malignant. If one or more B features were present in the absence of an M feature, it was classified as benign. If both M features and B features were present, or if none of the features was present, the simple rules were inconclusive.

SETTING

19 ultrasound centres in eight countries.

PARTICIPANTS

1938 women with an adnexal mass examined with ultrasound by the principal investigator at each centre with a standardised research protocol. Reference standard Histological classification of the excised adnexal mass as benign or malignant.

MAIN OUTCOME MEASURES

Diagnostic sensitivity and specificity.

RESULTS

Of the 1938 patients with an adnexal mass, 1396 (72%) had benign tumours, 373 (19.2%) had primary invasive tumours, 111 (5.7%) had borderline malignant tumours, and 58 (3%) had metastatic tumours in the ovary. The simple rules yielded a conclusive result in 1501 (77%) masses, for which they resulted in a sensitivity of 92% (95% confidence interval 89% to 94%) and a specificity of 96% (94% to 97%). The corresponding sensitivity and specificity of subjective assessment were 91% (88% to 94%) and 96% (94% to 97%). In the 357 masses for which the simple rules yielded an inconclusive result and with available results of CA-125 measurements, the sensitivities were 89% (83% to 93%) for subjective assessment, 50% (42% to 58%) for the risk of malignancy index, 89% (83% to 93%) for logistic regression model 1, and 82% (75% to 87%) for logistic regression model 2; the corresponding specificities were 78% (72% to 83%), 84% (78% to 88%), 44% (38% to 51%), and 48% (42% to 55%). Use of the simple rules as a triage test and subjective assessment for those masses for which the simple rules yielded an inconclusive result gave a sensitivity of 91% (88% to 93%) and a specificity of 93% (91% to 94%), compared with a sensitivity of 90% (88% to 93%) and a specificity of 93% (91% to 94%) when subjective assessment was used in all masses.

CONCLUSIONS

The use of the simple rules has the potential to improve the management of women with adnexal masses. In adnexal masses for which the rules yielded an inconclusive result, subjective assessment of ultrasonic findings by an experienced ultrasound examiner was the most accurate diagnostic test; the risk of malignancy index and the two regression models were not useful.

[Short-term effect of an estroprogestin containing ethinylestradiol 20 mcg + drospirenone 3 mg in 24+4 regimen at hormonal and cutaneous level in ovarian hyperandrogenism]

AIM

evaluate the efficacy of an estroprogestin EP containing 20 mcg ethinilestradiol (EE) and 3 mg drospirenone (DRSP) in the treatment of hyperandrogenism.

METHODS

In this study, twenty hyperandrogenic patients were treated with an EP containing EE 20 mcg and DRSP 3 mg in 24+4 regimen for three months. Skin evaluation was performed both quantitatively and qualitatively.

RESULTS AND CONCLUSION

This EP combination showed, after a short-term treatment (three months) to decrease significantly seborrhea, acne, and circulating androgens (testosterone, deidroepiandrosterone sulphate, and androstenedione), while increased sex hormone binding globulin levels. Moreover, this EE 20 mcg/DRSP 3mg EP combination changed some parameters of skin quality, increasing corneometry (a parameter related to skin hydration), and reduced trans epidermal water loss (TEWL, a parameter related to skin evaporation), and erythema (a parameter related to skin inflammation). These results could be taken into account in individualizing the treatment of hyperandrogenic patients.

Prospective external validation of the 'ovarian crescent sign' as a single ultrasound parameter to distinguish between benign and malignant adnexal pathology

OBJECTIVE

To determine the sensitivity and specificity of the 'ovarian crescent sign' (OCS)-a rim of normal ovarian tissue seen adjacent to an ipsilateral adnexal mass-as a sonographic feature to discriminate between benign and malignant adnexal masses.

METHODS

The patients included were a subgroup of patients participating in the International Ovarian Tumor Analysis (IOTA) Phase 2 study, which is an international multicenter study. The subgroup comprised 1938 patients, with an adnexal mass, recruited from 19 ultrasound centers in different countries. All patients were scanned using the same standardized ultrasound protocol. Information on more than 40 demographic and ultrasound variables were collected, but the evaluation of the OCS was optional. Only patients from centers that had evaluated the OCS in > or = 90% of their cases were included. The gold standard was the histological diagnosis of the adnexal mass. The ability of the OCS to discriminate between borderline or invasively malignant vs. benign adnexal masses, as well as between invasively malignant vs. other (benign and borderline) tumors, was determined and compared with the performance of subjective evaluation of ultrasound findings by the ultrasound examiner.

RESULTS

The OCS was evaluated in 1377 adnexal masses from 12 centers, 938 (68%) masses being benign, 86 (6%) borderline, 305 (22%) primary invasive and 48 (3%) metastases. The OCS was present in 398 (42%) of 938 benign masses, in 14 (16%) of 86 borderline tumors, in 18 (6%) of 305 primary invasive tumors (one malignant struma ovarii, one uterine clear cell adenocarcinoma and 16 epithelial carcinomas, i.e. four Stage I and 12 Stage II-IV) and in two (4%) of 48 ovarian metastases. Hence, the sensitivity and specificity for absent OCS to identify a malignancy was 92% and 42%, respectively, and the positive and negative likelihood ratios (LR+ and LR-, respectively) were 1.60 and 0.18. Subjective impression performed significantly better than the OCS. Sensitivity and specificity were 90% and 92%, respectively, LR+ was 11.0 and LR- was 0.10. For discrimination between invasive vs. benign or borderline tumors, the sensitivity for absent OCS was 94%, the specificity was 40%, the LR+ was 1.58 and the LR- was 0.14.

CONCLUSION

This study confirms previous reports that the presence of the OCS decreases the likelihood of invasive malignancy in adnexal masses. However it is a poor discriminator between benign and malignant adnexal masses.

Transvaginal Color Doppler Imaging in the Detection of Ovarian Cancer in a Large Study Population

Introduction:

The aim of the study was to compare the diagnostic accuracy of grayscale sonography and that of color Doppler imaging in the diagnosis of ovarian malignancy in a prospective study by the Sardinia-Navarra group.

Methods:

The study was performed as a collaborative work at the 2 European university departments of obstetrics and gynecology between 1997 and 2007. A total of 2148 pelvic masses in 1997 women on whom transvaginal sonography were performed before surgical exploration were included in the study. An adnexal mass was first studied in grayscale sonography, and any cystic mass in which the echo architecture was not suggestive of benign tumor was categorized as malignant. Second, any solid excrescences or solid portions of the tumor were evaluated with color/power Doppler sonography. A mass was graded malignant if flow was shown within the excrescences or the solid areas and benign if there was no flow or if flow was only peripheral.

Results:

Four hundred sixty-eight masses were malignant. Color Doppler evaluation was more accurate in the diagnosis of adnexal malignancies in comparison with grayscale sonography because of a significantly higher specificity (94% vs 89%, P = 0.001), with similar sensitivity (95% vs 98%, P = 0.44). The pretest probability of ovarian cancer was 22%, and this probability rose to 82% when the diagnosis was suggested by color Doppler evaluation. The diagnostic accuracy of the tests was also dependent on menopausal status.

Conclusions:

The evaluation of vessel distribution by color Doppler sonography in adnexal masses increases the diagnostic accuracy of grayscale sonography in the detection of adnexal malignancies in a large study population.

Obesity-related lipid profile and altered insulin incretion in adolescents with polycystic ovary syndrome

PURPOSE

The objective of this study was evaluate influence of body mass index (BMI), hyperinsulinemia and/or insulin resistance (IR), and androgens on the lipid profile of adolescent polycystic ovary syndrome (PCOS).

METHODS

A total of 71 PCOS and 94 healthy adolescent girls from a Southern Italian region were included in the study. At day 5-8 of menstrual cycle, patients underwent a 75-g oral glucose tolerance test to evaluate insulin levels; lipid and homocysteine levels were also assessed, baseline hormonal assays and ultrasound examination performed, and anthropometric characteristics measured.

RESULT

No differences were observed in the incidence of overweight or obesity and total cholesterol, high-density lipoprotein (HDL) cholesterol level, low-density lipoprotein cholesterol level; triglycerides and homocysteine levels did not differ between PCOS and control groups. All fasting metabolic indexes were similar, whereas insulin secretion after glucose load (I-AUC) was significantly higher in PCOS subjects. Total cholesterol levels were significantly related to waist-hip ratio (WHR). Low-density lipoprotein level was positively correlated with BMI, waist, WHR, and homeostasis model assessment (HOMA) but not I-AUC. Findings obtained for HDL correlated negatively to the same parameters, being also negatively correlated to both fasting insulin and HOMA, but not I-AUC. Moreover, HDL was positively correlated to circulating androstenedione (A) and negatively to circulating testosterone (T) levels. Triglycerides seemed to correlate positively with body BMI, waist, and WHR, and negatively with A levels. Homocysteine levels correlated positively with plasma triglyceride content.

CONCLUSION

In the adolescent population studied, no differences were revealed in lipid profile between PCOS and controls. The PCOS is not a discriminant factor. The anthropometric characteristics resulted in the primary factor influencing the lipid derangement, confirming the importance of treating obesity at an early age to reduce morbidity rates. Hyperinsulinemia and IR, peculiarities of PCOS capable of influencing long-term evolution into cardiovascular diseases and diabetes mellitus, are not associated with worse lipid profile. Young patients should be encouraged and motivated to change their lifestyle, with the aim of losing weight and thus reducing risk of onset of overt dyslipidemia.

Intraoperative sentinel lymph node detection by vital dye through laparoscopy or laparotomy in early endometrial cancer

BACKGROUND AND OBJECTIVES

Recent studies reported the feasibility of intraoperative lymphatic mapping in women with endometrial cancer but none of these studies compared the sentinel lymph nodes (SLNs) detection rates obtainable through laparoscopy or laparotomy. The purpose of this study was to address this issue.

METHODS

Thirty-four patients with clinical stage I-II endometrial cancer were enrolled in this prospective comparative trial. Four milliliters of Patent Blue Violet were injected into the cervix after the induction of general anesthesia. The assessment of SLNs was done in 17 patients through laparoscopy and in 17 patients through laparotomy as first step of systematic pelvic lymphadenectomy. Both SLNs and non-SLNs were evaluated for micrometastases.

RESULTS

The SLNs detection rate was significantly higher (82%) for laparoscopy than for laparotomy (41%; P = 0.008). Pelvic lymph node metastases were present in 6 out of 34 patients (18%) but only 3 (50%) of these patients were correctly identified.

CONCLUSIONS

SLNs detection rate is significantly higher through laparoscopy than through laparotomy after vital dye pericervical injection but intraoperative vital dye pericervical injection is not reliable as part of standard care for predicting lymphatic spread in women with early stage endometrial cancer.

Single access laparoscopy for adnexal pathologies using a novel reusable port and curved instruments

OBJECTIVE

To present our initial experience using single access laparoscopic surgery for the treatment of benign adnexal pathologies.

METHODS

Sixteen patients with benign adnexal pathologies underwent salpingoophorectomy (n=9), ovarian cyst enucleation (n=5), or salpingectomy (n=2) using a laparoendoscopic single site approach with a new multiport reusable trocar and flexible and curved-as well as standard-laparoscopic instruments.

RESULTS

Conversion to a multi-access standard laparoscopic technique was not required in any patient and no intraoperative complications were observed. Postoperatively, one umbilical scar infection was detected. Mean operative time was 42 minutes.

CONCLUSION

Laparoscopic single site enucleation for adnexal pathologies is feasible, safe, and effective, and has good results for cosmetic appearance and postoperative pain. Use of specialized instruments and standardization of the technique affect surgical ergonomy and operating time.

Pregnancy care in two adolescents perinatally infected with HIV

We describe the main issues encountered in pregnancy care in two perinatally infected adolescents with HIV. Despite the young maternal age, both mothers complied well with visits and treatment during pregnancy and delivered at week 38 through elective caesarean section. Both, however, missed the regular gynaecological and the routine HIV visits scheduled after pregnancy. Both infants following HIV exposure were confirmed HIV-negative at the end of tests performed in the first year of life. A growing number of similar cases is expected as perinatally infected children enter adolescence and become sexually active. These two cases indicate the feasibility of an adequate pregnancy care in very young HIV-positive women, but suggest that potential difficulties may be encountered in this population in maintaining optimal care after delivery. Such objectives might be better obtained with a timely transition of adolescents with HIV from paediatric clinics to a multiservice care setting which includes infectious diseases clinics, obstetric and gynaecologic departments and, particularly, counselling and educational services.
