RESUMEN
BACKGROUND: Distinguishing hydatidiform moles (HMs) from nonmolar specimens and the subclassification of HM are important because complete hydatidiform mole (CHM) is associated with an increased risk of development of gestational trophoblastic neoplasia. However, diagnosis based solely on morphology has poor inter-observer reproducibility. Recent studies have demonstrated that the use of p57KIP2 immunostaining improves diagnostic accuracy for CHM. OBJECTIVES: To evaluate the accuracy of p57KIP2 immunostaining compared with molecular genotyping for the diagnosis of CHM. SEARCH STRATEGY: Major databases were searched from inception to March 2017 using the terms 'hydatidiform mole', 'p57', and 'genotyping', with their variations, and the search limit for the relevant study design. SELECTION CRITERIA: Any cross-sectional study, case series, case-control study, cohort study, or clinical trial that evaluated the accuracy of p57KIP2 immunostaining for the diagnosis of CHM compared with genotyping was included. Case reports, narrative reviews, expert opinions, and animal testing were excluded. DATA COLLECTION AND ANALYSIS: Extracted accuracy data were tabulated and pooled using a hierarchical bivariate random effects model. MAIN RESULTS: Bivariate meta-analysis produced a summary sensitivity of 0.984 (95% CI: 0.916-1.000) and specificity of 0.625 (95% CI: 0.503-0.736) with significant heterogeneity for specificity (I2 = 71.8, chi-square P = 0.029). The pooled summary diagnostic odds ratio was 56.54 (95% CI: 11.03-289.74) with no heterogeneity (I2 = 0.00%, chi-square P = 0.67). The diagnostic performance of the test was high with an area under the curve of (AUC) 0.980. CONCLUSIONS: p57KIP2 immunostaining is accurate when diagnosing CHM. It can be used as an adjunct test in a combination algorithmic approach. TWEETABLE ABSTRACT: A meta-analysis to evaluate the accuracy of p57KIP2 compared with genotyping to diagnose CHM.

BACKGROUND: Over the years, hysteroscopy has been increasingly performed for various gynecological disorders. In this study, we present a review of hysteroscopic procedures performed over a 2-year period analyzing the complications associated with it. METHODS: Seven hundred twenty-six hysteroscopic procedures performed at the Department of Gynecology and Obstetrics, University of Kiel over a period of 2 years were reviewed retrospectively using the GynReg database in the department. Indications, intraoperative diagnoses, and complications were particularly highlighted. RESULTS: The most common indications for the procedure were abnormal vaginal bleeding, endometrial ablation, polypectomy, and myomectomy. The most common findings were uterine polyps, submucous myoma, and hyperplastic endometrium. The complication rate was 1.65% of total hysteroscopies. False passage and uterine perforation were the most common acute complications. No late complications occurred. CONCLUSIONS: Correlating our data with that found elsewhere, we find hysteroscopy to be a safe, minimally invasive procedure with a very low rate of complications.
