Early pregnancy losses occur in 10-20% of all pregnancies. Surgical evacuation has always been the mainstay of management of miscarriages. The main aim of this study was to understand the success rate of expectant management of miscarriage with regards to gestational sac size and period of gestation. The secondary outcome was to measure the satisfaction level and the rate of pregnancy after 6 month of expectant management. Patients diagnosed with missed miscarriages were requested to choose between expectant or surgical management. Those decided for expectant management on “wait and watch” approach were assessed weekly up to 5 completed weeks until complete miscarriage was achieved spontaneously. Surgical evacuation was performed if medically indicated or requested by the patients at any time or at the end of fifth week if complete miscarriage was not achieved. Out of 212 cases, 75 (35.4%) opted for expectant management. Complete miscarriage was achieved in 85.3% of subjects by the end of fifth weeks respectively. Mean of Gestational sac size and period of gestation was not found to influence the success rate of complete spontaneous miscarriage in the expectant management. No morbidity was recorded during the five weeks of the study period. Mean satisfaction score was 9.7±8.3. Pregnancy occurred in 47% of patients within 6 months follow up. The Receiver operation characteristic (ROC) curve analysis suggested the end of second week as the cut off for surgical intervention. This study revealed that expectant management of missed miscarriage is a reliable management of missed miscarriage within the first two weeks.
Introduction: Suspicious adnexal masses need to be investigated thoroughly as it may represent ovarian cancer, which is the fourth most common gynaecological cancer in Malaysia. Conventional cross sectional imaging may reveal non-specific findings, thus lead to unnecessary biopsies. 18F-Fluorodeoxyglucose positron emission tomography/ computed tomography (18F-FDG PET/CT) has emerged as a useful tool, for characterization of indeterminate adnexal masses. Most studies have been conducted in Western population, and little information is available in Asian population in general and Malaysian population in particular. Methods: Prospective study of women with suspicious adnexal masses, referred to the Centre for Nuclear Diagnostic Imaging, Universiti Putra Malaysia to undergo pre-operative whole-body contrast-enhanced 18F-FDG PET/CT scans from January 2014 to January 2016. Subjects underwent Contrast-Enhanced Computed Tomography (CECT) scans followed by positron emission tomography (PET) scans using a hybrid scanner. Two radiologists analyzed the CECT and PET/CT images by consensus; blinded to the HPE results. Then the PET/CT findings were correlated with HPE results as the gold standard. Results: 11 whole-body PET/CT scans and 18 adnexal masses (12 HPE-proven malignant lesions and 6 benign lesions) were analyzed. The sensitivity, specificity, PPV, and NPV of CECT alone compared to PET/CT was 91.7%, 50.0%, 78.6%, and 75.0% vs. 91.7%, 100%, 100% and 85.7% respectively. Conclusions: Improved diagnostic accuracy for characterizing benign and malignant adnexal masses can be achieved using contrast-enhanced 18F-FDG PET/CT, making it a potential investigation of choice which can help in treatment planning.
