To Analysis the Relapse of Endometriosis's Patient Treated with Ultrasound Guided Aspiration of Ovarian Endometrioma and Ethanol Sclerotherapy by Using Decision Tree

摘要

Ultrasound guided aspiration of ovarian endometrioma had been tried as an alternative therapeutic modality in patients who undesired for surgery or surgical approach is contraindicated since 1991. But simple aspiration leaves the capsule without treatment that results in high recurrence rate (28.5% to 100%). In order to reduce recurrence after aspiration, some groups have combined ultrasound-guided aspiration with instillation of tetracycline, methotrexate, recombinantrninterleukin-2, with the recurrence rates of 46.9%, 18.1%, and 40% respectively. Noma et al. reported that conduct of ethanol instillation for more than 10 minutes particularly for a case with a single endometrial cyst is considered most effective from the standpoint of recurrence (14.9%).rnThis research works together with Reproduction Medicine Center of Medicine Center in Taiwan Area. Our goal is to analyse patients with recurrent pelvic cyst who underwent surgical intervention. The research data basis clinical diagnosis, symptoms and medical intervention classification, and define the cyst numbers as forecast project target. We try to use decision tree, methodology of data mining technology, to find the useful characteristic as well as each other mutually connection. The expectation can discover with examines the data and the clinical symptom correlation important decision-making factor, provides clinical faculty doctor to diagnose and the treatment reference.
