Hysterectomy by transvaginal natural orifice transluminal endoscopic surgery: An Italian initial experience.

Background: The aim of this study is to evaluate the initial feasibility, safety, and outcomes of hysterectomy performed by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) at three institutions in Italy. Materials and methods: All women who underwent vNOTES hysterectomy ± salpingo-oophorectomy for benign indications at three tertiary referral medical centers between July 2019 and April 2021 were included in a retrospective analysis. All vNOTESs were performed with the use of Alexis® and Vpath Gel paths® (Applied Medical). Perioperative data were extracted from patient records. Patient satisfaction and dyspareunia were prospectively inquired about at 60 days and 6 months. Results: Forty-six patients underwent vNOTES in the study period. Indications for surgery included myomas ± metrorrhagia (52.2%), H-Sil/in situ cervical cancer (10.7%), adenomyosis ± metrorrhagia (8.7%), BRCA 1-2 mutations (6.5%), endometrial hyperplasia (6.5%), ovarian cyst + history of breast cancer (6.5%), metrorrhagia (6.5%), and hydatidiform mole (2.2%). The mean operation time was 91.1 (±32.6) minutes. The mean hemoglobin drop was 1.2 (±0.8). The mean visual analog scale at 24 h for post-operative pain was 3.3 (±1.8). Secondary to our limited experience with the surgical technique, we favor discharge only from day 1. The mean length of hospital stay was 2 (±1.4) days. Two conversions to conventional laparoscopy were reported (4.3%), due to an obliterated pouch of Douglas and a preoperative complication. Two post-operative complications were reported (4.3%). Overall, our data on peri- and post-operative outcomes are similar to those already published for vNOTES. Conclusion: Our initial experience suggests that introducing vNOTES as an alternative to conventional surgery is feasible and may offer some advantages in selected women.

Prediction of Tubal Ectopic Pregnancy Using Offline Analysis of 3-Dimensional Transvaginal Ultrasonographic Data Sets: An Interobserver and Diagnostic Accuracy Study.

OBJECTIVES: To assess interobserver reproducibility in detecting tubal ectopic pregnancies by reading data sets from 3-dimensional (3D) transvaginal ultrasonography (TVUS) and comparing it with real-time 2-dimensional (2D) TVUS. METHODS: Images were initially classified as showing pregnancies of unknown location or tubal ectopic pregnancies on real time 2D TVUS by an experienced sonologist, who acquired 5 3D volumes. Data sets were analyzed offline by 5 observers who had to classify each case as ectopic pregnancy or pregnancy of unknown location. The interobserver reproducibility was evaluated by the Fleiss κ statistic. The performance of each observer in predicting ectopic pregnancies was compared to that of the experienced sonologist. Women were followed until they were reclassified as follows: (1) failed pregnancy of unknown location; (2) intrauterine pregnancy; (3) ectopic pregnancy; or (4) persistent pregnancy of unknown location. RESULTS: Sixty-one women were included. The agreement between reading offline 3D data sets and the first real-time 2D TVUS was very good (80%-82%; κ = 0.89). The overall interobserver agreement among observers reading offline 3D data sets was moderate (κ = 0.52). The diagnostic performance of experienced observers reading offline 3D data sets had accuracy of 78.3% to 85.0%, sensitivity of 66.7% to 81.3%, specificity of 79.5% to 88.4%, positive predictive value of 57.1% to 72.2%, and negative predictive value of 87.5% to 91.3%, compared to the experienced sonologist's real-time 2D TVUS: accuracy of 94.5%, sensitivity of 94.4%, specificity of 94.5%, positive predictive value of 85.0%, and negative predictive value of 98.1%. CONCLUSIONS: The diagnostic accuracy of 3D TVUS by reading offline data sets for predicting ectopic pregnancies is dependent on experience. Reading only static 3D data sets without clinical information does not match the diagnostic performance of real time 2D TVUS combined with clinical information obtained during the scan.

Methotrexate vs placebo in early tubal ectopic pregnancy: a multi- centre double-blind randomised trial.

BACKGROUND: In the 21st century, tubal ectopic pregnancies (EPs) are diagnosed earlier in their natural history due to transvaginal ultrasound technology. More women are haemodynamically stable and therefore can be offered non-invasive outpatient management with systemic Methotrexate (MTX). However there is no evidence that MTX is necessary in all these early EPs, as many may resolve spontaneously in the absence of any treatment. To date there are no published randomized trials comparing systemic MTX with a placebo. The aim of this study is to verify if MTX is more effective than the placebo in women with tubal EP and rising/plateauing serum human chorionic gonadotrophin (hCG) levels. METHODS/DESIGN: This is a multi-centre double-blind randomized controlled trial conducted in Australia. Haemodynamically stable women with a confirmed ultrasound diagnosis of tubal EP and a rising/plateauing serum hCG & < 1500 IU/L are eligible for the trial. Women with a declining serum hCG, hCG > 1500 IU/L at 48 hrs, viable tubal EP, severe abdominal pain, evidence of haemoperitoneum on ultrasound, diagnostic uncertainty, non-tubal ectopic pregnancy, or women with contraindications to MTX will be excluded. Systemic MTX in a single dose intramuscular regimen (50mg/m2) is compared to an identical placebo in an outpatient setting. All women will attend for a serum hCG measurement on day 4. Provided patients are haemodynamically stable, they will attend for another blood test on day 7. If a decline in serum hCG > 15% between days 4 - 7 is observed, weekly blood tests will be scheduled until undetectable hCG levels. If serum hCG levels increase or decrease < 15% between days 4 - 7, a second dose of MTX will be given and weekly blood tests will be scheduled until undetectable serum hCG. If any increase in serum hCG > 15% between days 4 - 7 or at any subsequent follow-up, women will be treated with MTX. Primary outcome measure is treatment success, defined as uneventful decline of serum hCG to an undetectable level ( < 5 IU/L) by the initial intervention. Secondary outcome measures are re-interventions (additional systemic MTX injections and/or surgery for haemodynamic instability/trophoblast persistence), treatment complications and length of follow-up. DISCUSSION: This trial will clarify the actual effectiveness of MTX in haemodynamically stable women with an early tubal EPs and rising or plateauing hCG.

The use of power Doppler colour scoring to predict successful expectant management in women with an incomplete miscarriage.

OBJECTIVE: To evaluate whether the use of power Doppler to confirm the presence or absence of blood flow within retained products of conception (RPC) in women with an incomplete miscarriage can predict subsequent successful expectant management. METHODS: Prospective observational study in the Acute Gynaecology and Early Pregnancy Unit (AGEPU) at Nepean Hospital from November 2006 to February 2009. Incomplete miscarriage was defined by the presence of a measurable focus of hyperechoeic material, in three planes, within the endometrial cavity using two-dimensional greyscale transvaginal ultrasound (TVS). Subjective qualitative power Doppler colour scoring (PDCS) of the RPC was performed. The vascularization of the RPC was scored using the colour scoring system of the International Ovarian Tumour Analysis (IOTA) group. PDCS 1 meant absence of vascularity, PCDS 2 represented minimal vascularity, PDCS 3 rather strong vascularity and PDCS 4 very strong vascularity. The correlation between the PDCS and successful expectant management of miscarriage was analysed. The volume of RPC was calculated using the ellipsoid formula and then compared with both the PDCS and the outcome of expectant management. Successful expectant management was defined as the resolution of symptoms and the absence of RPC on follow-up TVS. RESULTS: A total of 1395 consecutive pregnant women underwent TVS. Of them, 198 women were diagnosed with an incomplete miscarriage; 172 were managed expectantly. Complete data were available on 158 cases. In total 84.8% (134/158) were managed successfully whilst 15.2% (24/158) failed expectant management. Of the total, 89% (121/136) of women with a PDCS 1 had successful expectant management compared with 57.1 (8/14) with PDCS 2 and 62.5% (5/8) with PDCS 3. Comparing absence of flow (PDCS 1) to presence of flow (PDCS 2 or more), the rate of success was significantly higher in the first group (89 versus 60.9%, Fisher's exact test P= 0.00136). In the prediction of success, the absence of flow showed a sensitivity, specificity, positive predictive value, negative predictive value and positive likelihood ratio of 90.3, 37.5, 89, 40.9% and 1.445 (95% confidence interval: 1.055-1.979), respectively. There was no correlation between the volume of RPC and the PDCS; and there was no relationship between the volume of RPC and the success of expectant management. CONCLUSIONS: PDCS can predict the likelihood of successful expectant management of incomplete miscarriage. The absence of flow on power Doppler is associated with a significant improvement in the rate of successful expectant management. This new approach may be helpful in quantifying the chances of successful expectant management in those women with an incomplete miscarriage at the primary scan.

Is pouch of Douglas obliteration a marker of bowel endometriosis?

STUDY OBJECTIVE: To estimate the clinical significance of pouch of Douglas (POD) obliteration in women undergoing laparoscopic excision of endometriosis. DESIGN: Prospective study (Canadian Task Force Classification II-2). SETTING: University-affiliated tertiary referral center for endometriosis. PATIENTS: A total of 454 consecutive women who underwent laparoscopic surgery for treatment of pelvic pain or infertility-associated endometriosis between October 2004 and September 2008. INTERVENTIONS: Demographic, historical, and final surgical data were compared between women with and without POD obliteration at laparoscopy. Logistic regression analyses were performed to investigate the predictive value of POD obliteration at laparoscopy with regard to bowel endometriosis. MEASUREMENTS AND MAIN RESULTS: One hundred consecutive women with POD obliteration at laparoscopy were included. 58% (95% confidence interval [CI] 0.48-0.67, n = 58/100) of the women with POD obliteration required bowel surgery compared with 20% (95% CI 0.16-0.25, 72/354) of women without POD obliteration (p <.001). Of the POD obliteration group, 66% (95% CI 0.53-0.76) required bowel shaving, 12% (0.06-0.23) full segmental rectal resection, 9% (0.04-0.19) wedge rectal resection, 5% (0.02-0.14) full segmental rectosigmoid resection and 9% (0.04-0.19) a combination of the above. Bowel endometriosis was histologically confirmed in all women. CONCLUSION: POD obliteration at laparoscopy carries a high risk of bowel endometriosis and bowel surgery. This risk is three times higher than those without POD obliteration. Women with POD obliteration should be managed in tertiary referral centers for the treatment of endometriosis where colorectal input is available.

The use of intra-operative saline sonovaginography to define the rectovaginal septum in women with suspected rectovaginal endometriosis: a pilot study.

Objectives: The aim of this study was to perform saline sonovaginography (SVG) in women with suspected rectovaginal endometriosis (RVE) in order to establish the thickness of the rectovaginal septum (RVS) in this population and to predict the presence or absence of RVE. Methods: Prospective observational pilot study. Women undergoing laparoscopy for possible endometriosis on the basis of history or clinical examination were offered to participate in the study. All women underwent saline SVG during general anesthesia just prior to their laparoscopy. RVS nodules were visualised as hypoechoic lesions of various shapes. The sonologist predicted whether or not a nodule was present in the retrocervical area or in the RVS. The thickness of the posterior vaginal wall ± RVS was then taken at three points in the mid-sagittal plane: at the posterior fornix (retrocervical area), at the middle third of the vagina (upper RVS) and just above the perineal body (lower RVS). The diagnosis of RVE was established using the gold standards of laparoscopy and histological confirmation. The RVS thickness was then compared between women with RVE and the absence of RVE. Results: Twenty-three women were enrolled in the study. Mean age was 38 years (33-44 years). A history of endometriosis was present in 72.7% (8/11). RVE was confirmed in 17.4% (4/23). Visualisation of a hypoechoic nodule at saline SVG demonstrated sensitivity and specificity of 75% and 95%, respectively. All rectovaginal nodules were located in the retrocervical region. Mean diameter (SD) of RVE nodules was 27.3 (± 9.4) mm. Mean thickness of vaginal wall ± RVS at the posterior fornix, at the middle third of the vagina and just above the perineal body was 5.1, 1.4 and 4.0 mm, respectively. These measurements were not significantly different in the presence of a rectovaginal nodule. Conclusions: Using saline SVG, we have established the mean RVS thickness in a small group of women with suspected RVE. Although the numbers are small, there was no correlation between RVS thickness and presence of RVE. The visualisation of hypoechoic lesions at saline SVG seems to be the best ultrasonographic predictor for RVE. SVG is a valuable pre-operative tool for the assessment of RVS and for the prediction of RVE, which allows for the mapping and planning of advanced endometriosis surgery.

Principles and strategies for dealing with complications in laparoscopy.

PURPOSE OF REVIEW: To help surgeons and to make patients become fully aware of the risks of laparoscopic surgery. As complications are an inevitable reality of surgery, we need to be aware of the types of complications in a systematic way, train to respond in an appropriate way, and learn to communicate in a transparent and honest way to deal with complications in laparoscopic surgery. RECENT FINDINGS: This article aims to classify complications associated with laparoscopy according to the different phases in surgery and to promote a comprehensive strategy for dealing with them. SUMMARY: To promote a culture of risk management which delivers the benefits and minimizes the risks associated with laparoscopic surgery.

Mirena intra-uterine system: does it improve long term symptoms in women with chronic pelvic pain and/or endometriosis after laparoscopy? A multicentre randomized controlled trial.

BACKGROUND: Chronic pelvic pain (CPP) is a complex clinical scenario, which affects 15% of women. The published literature lacks a consistent definition of CPP. However according to Vercillini et al., CPP is defined by the duration and type of pelvic pain. CPP is present if the pelvic pain persists for more than 3 months duration and is constant or intermittent, cyclical or noncyclical in nature. Four types of pelvic pain have also been described and these include: cyclical pain during menstruation (dysmenorrhoea), deep dyspareunia, dyschezia and noncyclical pelvic pain. Therefore for the purposes of this study, CPP will be defined by these aforementioned types of pelvic pain and duration. METHODS: Multi-centre randomised controlled trial comparing Mirena IUS versus expectant management in women with CPP and/or dysmenorrhoea who undergo laparoscopic surgery. All women aged 18 - 45 years with CPP scheduled for laparoscopy will be eligible for inclusion. Women with a non-gynecological cause of pelvic pain, contraindications to the use of Mirena IUS, previous hysterectomy, contraindications to laparoscopy and/or general anesthesia, use of hormonal treatment in the preceding three months, underlying gynaecological malignancies or known ovarian cysts other than endometriomata will be excluded. Importantly, all randomised women with endometriosis noted at the time of surgery will have the disease excised laparoscopically. Routine excision of endometriosis at laparoscopy will be performed according to the anatomical location and type (superficial or deep infiltrating endometriosis (DIE)). Women will be followed for up to 24 months after laparoscopic surgery. RESULTS: The primary outcome measure is improvement of pelvic pain and/or of dysmenorrhoea post-laparoscopic surgery for women. Assuming a 30% reduction in pain for the expectantly managed group in order to detect a reduction in pain in the study group of 50% with an alpha of 0.05 and a beta of 0.20, the sample size was estimated at a minimum of 103 women per trial arm. DISCUSSION: This trial will provide evidence to validate the effectiveness or otherwise of progestogen-releasing IUS in treating women with CPP who undergo laparoscopy surgery. The pros and cons of both trial arms will offer guidance to clinicians in making the right treatment choice.

The value of laparoscopic skills courses.

OBJECTIVES: To evaluate the effectiveness of 'hands-on' laparoscopic skills course. METHODS: A prospective observational study conducted between May 2005 and June 2006. All gynaecologists who attended 'hands-on' laparoscopic skills course held over a five-day period were assessed initially and at the end of the intensive course. Subjective assessment involved each attendee self-scoring their own knowledge in laparoscopy in different fields; this was done using visual analog scoring (VAS). Objective assessment was done through multiple choice questions (MCQs) and motor skill tasks. The difference between the performances of each of the candidates at pre- and post-course periods was evaluated using the Wilcoxon signed rank test. P-values < 0.05 represented statistical significance. SETTING: Centre for Advanced Reproductive Endosurgery (CARE), Royal North Shore Hospital, University of Sydney, Sydney, Australia. RESULTS: Twenty-four consecutive gynaecologists have been enrolled in the study - 14 were specialists and ten were obstetrics and gynaecology trainees. Mean age was 44.4 years (range 35-58 years). Pre- and post-course subjective assessment measuring VAS improved significantly for all variables. Objective measurements of pre- and post-course mean MCQ results also improved significantly from 71% to 84.5%, respectively (P-value < 0.0001). There was dramatic improvement in the performing of motor skills in the dry laboratory. CONCLUSIONS: Laparoscopic skills workshops can improve both knowledge base and motor skills. Such courses result in a short-term measurable improvement. Future studies should focus on assessing the impact of such 'hands-on' courses to see if these skills are transferred to the operating room.

Abnormal uterine and post-menopausal bleeding in the acute gynaecology unit.

Abnormal uterine bleeding is one of the most common presentations in the acute gynaecology unit. The general principles of emergency care, including assessment of haemodynamic state, symptomatic relief as well as determination of underlying aetiology, apply to these women. We review different strategies in the diagnosis and investigation of abnormal uterine bleeding in both pre- and post-menopausal women. Transvaginal ultrasound (TVS) with colour Doppler is the cornerstone of initial management. TVS, in experienced hands, can reliably exclude the most common intra-cavitary pathologies including endometrial polyps and submucosal fibroids. Their exclusion, in pre-menopausal women, aids in the diagnosis of dysfunctional uterine bleeding. In post-menopausal women, the endometrial thickness reliably selects those who need further testing. If a thin and regular endometrium is visualised, malignancy is most unlikely. To allow for reliable evaluation of the endometrium, TVS has to be performed before endometrial sampling. Saline infusion sonohysterography (SIS) is most valuable in the detection of focal intra-cavitary lesions. TVS with or without SIS can provide enough information to avoid an unnecessary hysteroscopy. In this review, we will also discuss an evidence-based algorithm for the work-up of women with post-menopausal bleeding.

Recognising gestational trophoblastic disease.

Gestational trophoblastic disease (GTD) is a group of interrelated tumours originating from the placenta. Hydatidiform molar (HM) pregnancy is the most common form of GTD; this includes both partial hydatidiform molar (PHM) and complete hydatidiform molar (CHM) pregnancies. The importance of such a condition derives from its potential for persistent trophoblastic disease; this is noted to be more common after a CHM (10-20%) compared to a PHM (0.1-11%). The recent routine use of high-resolution trans-vaginal ultrasound (TVS) in early pregnancy has improved the recognition and thus pre-surgical diagnosis of molar pregnancy. Pre-surgical recognition aids planning of surgery, decreases intra-operative complications and identifies women with potential persistent trophoblastic disease. Despite the introduction of TVS, its performance in preoperative diagnosis is quite poor. This is primarily because of the histomorphometric features of the hydropic villi. A significant proportion of HM cases demonstrates minimal hydropic change in the first trimester and therefore is likely to remain unidentifiable by ultrasound examination prior to surgical evacuation, even with improved sonographer expertise. The overall sensitivity for the ultrasound diagnosis of HM is 50-86%. Ultrasound diagnosis of CHM can be made in approximately 80% of the cases, whilst ultrasound diagnosis of PHM is less accurate and nearly 70% of cases will be missed. Correlation of the ultrasonographic findings with human chorionic gonadotropin levels can further improve the recognition of HM pregnancy pre-surgery. Although ultrasound can be helpful in the diagnosis of molar pregnancies, histological confirmation is mandatory. Histological confirmation post-curettage is still the gold standard for the diagnosis of GTD. In this article, we critically evaluate the role of TVS in the pre-surgical recognition of GTD.

The management of ovarian pathology in pregnancy.

The extensive use of ultrasound in early pregnancy populations has led to more ovarian lesions being diagnosed incidentally in asymptomatic gravid women. The majority of these lesions are physiological in nature and tend to resolve spontaneously as the pregnancy progresses. Expectant management or a "watch and wait" approach is the benchmark standard of care for a woman with an ovarian mass diagnosed during pregnancy. This approach assumes the woman is relatively asymptomatic, and the likelihood of malignancy is negligible. The prevalence of malignancy in pregnancy is rare indeed, i.e. 1 in 15,000-32,000. It is the discriminatory ability of ultrasound, in experienced hands, to distinguish between benign and malignant ovarian lesions that allow appropriate triaging during pregnancy. Discriminating benign from malignant masses is crucial not only to optimize the management of malignancies, but also to avoid unnecessary intervention that may adversely affect maternal or foetal outcomes. This review will focus on the management of ovarian masses in pregnancy.

What determines the need to morcellate the uterus during total laparoscopic hysterectomy?

STUDY OBJECTIVE: To identify factors associated with the need to perform uterine morcellation during total laparoscopic hysterectomy (TLH). A secondary aim was to establish new cut-offs based on uterine weight for the probability of morcellation. DESIGN: Prospective observational study (Canadian Task Force Classification II-2). SETTING: Tertiary referral laparoscopic unit. PATIENTS: All women scheduled to undergo TLH in the study period were included. INTERVENTIONS: Age, parity, operating time, estimated blood loss, and final uterine weight at histology were recorded. Logistic regression analysis was performed to determine the factors associated with the need to perform uterine morcellation at the time of TLH. Multiple imputation (MI) was used to impute missing values. MEASUREMENTS AND MAIN RESULTS: A total of 112 consecutive women underwent TLH and were included in the final analysis. In all, 56 (50%) of 112 women underwent TLH without morcellation (i.e., it was possible to deliver the uterine specimen vaginally) and 56 (50%) of 112 women underwent TLH with morcellation (i.e., it was not possible to deliver the uterine specimen vaginally and, therefore, morcellation was performed). Median age in each group was 45 and 46 years, respectively. Sixteen (70%) of 23 nulliparous women underwent morcellation compared with 40 (45%) of 89 parous women. Multivariable logistic regression analysis revealed that nulliparity (OR = 6.45, 95% CI = 1.74-23.9) and uterine weight (OR/100-g increase = 4.97, 95% CI = 2.13-11.6) increased the odds of morcellation. All 20 women with a uterine weight of at least 350 g required morcellation. Based on the MI analysis results, uterine weight was at least 350 g in 1 of 5 patients, with 99.5% of the women having uterine weight of 350 g or more that required morcellation. CONCLUSION: Nulliparity and increasing uterine weight are associated with the need to perform uterine morcellation in TLH. Studies are needed to find a reliable method for estimating uterine weight preoperatively.

Sonorectovaginography: a new sonographic technique for imaging of the posterior compartment of the pelvis.

OBJECTIVE: We describe the use of a new sonographic technique for imaging of the posterior compartment of the pelvis: sonorectovaginography. METHODS: Sonorectovaginography uses instillation of fluids (saline solution and ultrasound gel) in the vagina, pouch of Douglas, and rectum for the purpose of creating acoustic interfaces between the vagina, cervix, rectum, and pouch of Douglas. We performed sonorectovaginography in a woman with chronic pelvic pain during laparoscopy. Urinary catheters were introduced into the rectum and vagina. Sterile saline solution was introduced into the abdominal cavity through a laparoscopic trocar and in the rectum via a rectal catheter. The transvaginal probe was then inserted, and sterile ultrasound gel was introduced into the vagina through the vaginal catheter under sonographic guidance. RESULTS: Sonorectovaginography has helped us create acoustic interfaces and enhanced simultaneous visualization of the vaginal walls, posterior vaginal fornix, retrocervical area, rectovaginal septum, rectal wall, and pouch of Douglas. CONCLUSIONS: Imaging of the posterior compartment of the pelvis is of paramount importance for identification of potentially difficult endometriosis cases, such as those complicated by obliteration of the pouch of Douglas or infiltration of the retrocervical area, rectovaginal septum, or vaginal or rectal wall. Sonorectovaginography may prove helpful in evaluating this compartment of the pelvis in women with suspected deep endometriosis. Its reproducibility, tolerability, and accuracy, however, need to be validated prospectively, and normative data for the rectovaginal septum also need to be established.

The hCG ratio can predict the ultimate viability of the intrauterine pregnancies of uncertain viability in the pregnancy of unknown location population.

BACKGROUND: To determine whether hCG ratio at 48 h can predict ultimate viability of intrauterine pregnancies of uncertain viability (IPUVs) in the pregnancy of unknown location (PUL) population. METHODS: Prospective observational study from June 2001 to October 2004. All women classified with PUL had serum hCG levels measured at 0 and 48 h to calculate hCG ratio (hCG 48/hCG 0 h). All women were followed up until final diagnosis: failing PUL, viable and non-viable intrauterine pregnancy (IUP), ectopic pregnancy. Those PULs found to have an IPUV at follow-up transvaginal ultrasound scan (TVS) were included in final analysis. RESULTS: During the study period, 12,572 consecutive first trimester women were scanned. One thousand and three (8%) women were classified PULs. Three hundred and seventy-nine (37.8%) PULs were confirmed IPUVs at follow-up scan. Complete data from 334 IPUVs were analyzed: 82.6% (276/334) viable IUPs and 17.4% (58/334) non-viable IUPs. Median hCG ratio was greater in viable IUPs [2.32, inter-quartile range (IQR) 1.16-4.77] compared with non-viable IUPs 1.83 (IQR 0.97-4.60). Sensitivity, specificity, positive and negative predictive value, positive and negative likelihood ratios of an hCG ratio >2.00 for the prediction of a viable IUP are 77.2%, 95.8%, 86.6%, 90.9%, 15.5, 0.24, respectively. In our population, an hCG ratio >2.00 increases the odds for a viable IUP from 0.42 to 6.46 post-test. CONCLUSIONS: The hCG ratio is significantly higher in those IPUVs which become viable IUPs compared with non-viable IUPs. New cut-offs for the hCG ratio need to be evaluated for the prediction of viability in the IPUV group of PULs.

Is ultrasound the new gold standard for the diagnosis of ectopic pregnancy?

Ultrasound technology and in particular the use of transvaginal imaging has taken the guesswork out of ectopic pregnancy diagnosis. The vast majority of ectopic pregnancies can and should be diagnosed with a high degree of certainty before management is commenced. More and more women with ectopic pregnancy are eligible for nonsurgical intervention because ultrasound has enabled clinicians to make the diagnosis much earlier in its natural history. We believe that laparoscopy, traditionally the gold standard in diagnosis of ectopic pregnancy, should not be used in modern management. There is more and more evidence to support the use of transvaginal ultrasound as the primary diagnostic tool for ectopic pregnancy. In this review we hoped to demonstrate that transvaginal ultrasound is the new gold standard for the diagnosis of ectopic pregnancy.
