BACKGROUND Approximately 15-20% of all clinically confirmed pregnancies end in a miscarriage. Intrauterine adhesions (IUAs) are a possible complication after miscarriage, but their prevalence and the contribution of possible risk factors have not been elucidated yet. In addition, the long-term reproductive outcome in relation to IUAs has to be elucidated. METHODS We systematically searched the literature for studies that prospectively assessed the prevalence and extent of IUAs in women who suffered a miscarriage. To be included, women diagnosed with a current miscarriage had to be systematically evaluated within 12 months by hysteroscopy after either spontaneous expulsion or medical or surgical treatment. Studies that included women with a history of recurrent miscarriage only or that evaluated the IUAs after elective abortion or beyond 12 months after the last miscarriage were not included. Subsequently, long-term reproductive outcomes after expectant (conservative), medical or surgical management were assessed in women with and without post-miscarriage IUAs. RESULTS We included 10 prospective studies reporting on 912 women with hysteroscopic evaluation within 12 months of miscarriage and 8 prospective studies, including 1770 women, reporting long-term reproductive outcome. IUAs were detected in 183 women, resulting in a pooled prevalence of 19.1% [95% confidence interval (CI): 12.8-27.5%]. The extent of IUAs was reported in 124 women (67.8%) and was mild, moderate and severe respectively in 58.1, 28.2 and 13.7% of cases. Relative to women with one miscarriage, women with two or three or more miscarriages showed an increased risk of IUAs by a pooled OR of 1.41 and 2.1, respectively. The number of dilatation and curettage (D&C) procedures seemed to be the main driver behind these associations. A total of 150 congenital and acquired intrauterine abnormalities were encountered in 675 women, resulting in a pooled prevalence of 22.4% (95% CI: 16.3-29.9%). Similar reproductive outcomes were reported subsequent to conservative, medical or surgical management for miscarriage, although the numbers of studies and of included women were limited. No studies reported long-term reproductive outcomes following post-miscarriage IUAs. CONCLUSIONS IUAs are frequently encountered, in one in five women after miscarriage. In more than half of these, the severity and extent of the adhesions was mild, with unknown clinical relevance. Recurrent miscarriages and D&C procedures were identified as risk factors for adhesion formation. Congenital and acquired intrauterine abnormalities such as polyps or fibroids were frequently identified. There were no studies reporting on the link between IUAs and long-term reproductive outcome after miscarriage, while similar pregnancy outcomes were reported subsequent to conservative, medical or surgical management. Although this review does not allow strong clinical conclusions on treatment management, it signals an important clinical problem. Treatment strategies are proposed to minimize the number of D&C in an attempt to reduce IUAs.

BACKGROUND Postoperative recovery is a considerable issue in studies comparing operative techniques of similar effectiveness. In recent years, a shift has occurred toward patient-centered study outcomes such as quality-of-life questionnaires. The objective of this article is to provide a systematic review of the literature on general postoperative, recovery-specific quality-of-life instruments and their measurement properties. METHODS We searched the databases EMBASE.com, Cinahl, PsycINFO, and PubMed for articles reporting on postoperative, recovery-specific quality-of-life instruments. A checklist was used to assess the revealed studies and instruments. Existing quality criteria were applied to the measurement properties to compare the instruments. RESULTS The search strategy identified 620 studies, of which 18 studies reported on 12 different postoperative, recovery-specific quality-of-life instruments. None of the instruments had been validated completely in line with the 8 quality criteria, which were used to assess the measurement properties. Two instruments were clearly superior, which were the Postdischarge surgical recovery scale and the Quality of recovery-40. CONCLUSIONS No fully validated instrument is available for the assessment of general postoperative recovery. We advise to use the Postdischarge surgical recovery scale and the Quality of recovery-40 in future validation and application studies on short-term postoperative recovery.

Incomplete healing of the scar is a recognized sequel of Cesarean section (CS) and may be associated with complications in later pregnancies. These complications can include scar pregnancy, a morbidly adherent placenta, scar dehiscence or rupture. To date there is uncertainty relating to the factors that lead to poor scar healing and how to recognize it. In recent years, there has been an increase in studies using ultrasound that describe scars as deficient, or poorly, incompletely or inadequately healed with few data to associate the morphology of the scar with the functional integrity of the lower segment of the uterus. There have been multiple attempts to describe CS scars using ultrasonography. Different terminology, methods and results have been reported, yet there is still no consensus regarding the prevalence, clinical significance or most appropriate method to describe the appearances of these scars. Developing a test that can predict the likelihood of women having problems associated with a CS scar is becoming increasingly important. On the other hand, understanding whether the ultrasound appearances of the scar can tell us anything about its integrity is not well supported by the research evidence. In this article we present an overview of ultrasound‐based definitions and methods used to describe CS scars. We also present information relating to the performance of alternative techniques used to evaluate CS scars. Having examined the current evidence we suggest a standardized approach to describe CS scars using ultrasound so that future studies can be meaningfully compared. Copyright

OBJECTIVES To assess the cost-effectiveness of transvaginal sonography (TVS) in the diagnostic work-up of women with postmenopausal bleeding. METHODS We performed a decision analysis in which we estimated life expectancy and cost of four strategies for the evaluation of postmenopausal bleeding: TVS (I), TVS and office endometrial biopsy (II), TVS and hysteroscopy (III), and endometrial biopsy (IV). In strategies incorporating TVS, calculations were performed for three different cut-off values between 3 and 9 mm double layer. Expectant management, i.e. no diagnosis or treatment was considered to be the reference strategy to which the other four strategies were compared. Data were obtained from the published literature. In extensive sensitivity analyses, we varied patients age, discount rate, prevalence of endometrial carcinoma and atypical hyperplasia, and costs. RESULTS The strategy with endometrial biopsy and the strategy with TVS followed by endometrial biopsy in case of an increased endometrial thickness were the most cost-effective strategies. The strategy starting with endometrial biopsy was the most cost-effective when the prevalence of endometrial carcinoma was > or =15.3%, whereas the strategy with TVS and endometrial biopsy was the most cost-effective for women in which the prevalence of endometrial carcinoma was lower. In these strategies, a cut-off level for abnormality of 9 mm resulted in lowest cost per life-year gained. CONCLUSIONS TVS is of use in women with postmenopausal bleeding and a probability of endometrial carcinoma below 15%.

Effectiveness of Abdominal Cerclage Placed via Laparotomy or Laparoscopy: Systematic Review

Nicole B. Burger; Hans A.M. Brölmann; J.I. Einarsson; Anton Langebrekke; Judith A.F. Huirne

Preterm delivery remains a primary cause of neonatal morbidity and mortality. One cause of preterm birth is cervical incompetence. In women with a shortened or absent cervix or in those in whom previous vaginal cerclage failed, abdominal cerclage may be recommended. We performed a systematic literature search of PubMed, EMBASE, and the Cochrane database. Thirty-one eligible studies were selected. Six studies (135 patients) reported on the laparoscopic approach, and 26 (1116 patients) on the abdominal approach. Delivery of a viable infant at 34 weeks of gestation or more varied from 78.5% (laparoscopic) to 84.8% (abdominal). Second-trimester fetal loss occurred in 8.1% (laparoscopic) vs 7.8% (abdominal), with no reported third-trimester losses (laparoscopic) vs 1.2% (abdominal). We conclude that abdominal cerclage is associated with excellent results as treatment of cervical incompetence, with high fetal survival rates and minimal complications during surgery and pregnancy. Further studies are needed to differentiate which method is superior.

STUDY OBJECTIVE To evaluate the protocol for confirmation of satisfactory Essure placement using transvaginal ultrasound. DESIGN Prospective multicenter cohort study (Canadian Task Force classification II-2). SETTING Outpatient departments of 4 teaching hospitals in the Netherlands. PATIENTS Eleven hundred forty-five women who underwent hysteroscopic sterilization using the Essure device between March 2005 and December 2007. INTERVENTION Transvaginal ultrasound examination 12 weeks after uncomplicated successful bilateral placement or as indicated according to the transvaginal ultrasound protocol after 4 weeks, and hysterosalpingography (HSG) at 12 weeks to confirm correct placement of the device after 3 months. MEASUREMENTS AND MAIN RESULTS The rate of successful placement was 88.4% initially. In 164 women (15%), successful placement was confirmed at HSG according the protocol. In 9 patients (0.84%), incorrect position of the device was observed at HSG. The cumulative pregnancy rate after 18 months was 3.85 per thousand women. CONCLUSION Transvaginal ultrasound should be the first diagnostic test used to confirm the adequacy of hysteroscopic Essure sterilization because it is minimally invasive, averts ionizing radiation, and does not decrease the effectiveness of the Essure procedure.
