ABSTRAK
Latar Belakang: Endometriosis merupakan kondisi yang sering ditemukan pada wanita usia reproduksi. Keterlambatan dignosis masih menjadi kendala. Saat ini, metode diagnosis non invasif termasuk transvaginal sonography telah direkomendasikan. Penelitian ini bertujuan mengevaluasi akurasi transvaginal sonogrpahy untuk mendiagnosis kista endometriosis di RS Cipto MangunkusumoMetode: Penelitian ini merupakan penelitian uji diagnostik yang dilakukan di RS Cipto Mangunkusumo pada Januari 2014 ? Juni 2015. Subjek penelitian merupakan pasien rawat jalan dengan kecurigaan kista endometriosis berdasarkan anamnesis dan pemeriksaan fisik. Pasien kemudian diperiksa transvaginal sonography oleh pemeriksa berpengalaman sesuai dengan protokol penelitian. Selanjutnya, pemeriksaan histologi dengan sediaan masa yang diambil dari prosedur operasi dijadikan baku emasHasil: Terkumpul 98 pasien yang dianalisis. Kista endometriosis terkonfirmasi pada 85 pasien (86,7%) berdasarkan pemeriksaan histologi. Akurasi, sensitivitas, spesifisitas, nilai duga positif dan nilai duga negatif transvaginal sonography yakni 84,9 (71,0-98,8)%, 92,9%, 76,9%, 96,3%, and 62,5%. Transvaginal sonography memiliki area under the curve yang lebih tinggi secara signifikan dibandingkan dengan hanya pemeriksaan fisik (84,9% vs 78,8%).Kesimpulan: Transvaginal sonogprahy bermanfaat untuk mendiagnosis kista endometriosis dan dapat direkomendasikan dalam praktik sehari-hari

ABSTRACT
Background: Endometriosis is common among reproductive age women. Late diagnosis is still the main concern. To date, non-invasive diagnostic test including transvaginal sonography is recommended. This study aimed to evaluate the accuracy of transvaginal sonography to diagnose endometriosis cyst among patients in Cipto Mangunkusumo Hospital.Method: This was a diagnostic study performed in Cipto Mangunkusumo Hospital from January 2014 to June 2015. Outpatients with suspicion to have endometrial cyst based on patients? history and clinical examination were recruited. Patients were then scanned by experienced sonologist using transvaginal sonography following our research protocol. The gold standard was histologic finding of removed surgical massResults: A total of 98 patients were analyzed. Endometrial cyst was confirmed by histology among85 patients (86.7%). The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of transvaginal sonography were 84.9 (71.0-98.8)%, 92.9%, 76.9%, 96.3%, and 62.5%, respectively. Transvaginal sonogpraphy significantly had higher area under the curve compared to clinical examination alone (84.9% vs 78.8%).Conclusion: Transvaginal sonography appears to be usefull to diagnose endometriosis cyst among outpatients and recommended in daily clincial practice
