Leiomyoma, Uterine

The PLUM Study is a randomized, double-blinded, 2-arm, parallel-group, placebo-controlled trial is designed to compare the efficacy of letrozole versus placebo on leiomyoma-related symptoms and quality of life as well as leiomyoma and uterine size.

The study aims to study the effect of simvastatin on the size of uterine fibroids.

Research Purpose The purpose of this study is to explore whether the application of a single-channel uterine fibroid morcellation system compared to a multi-channel specimen retrieval bag during laparoscopic myomectomy can shorten the operative time and improve the efficiency of fibroid removal. Research Design This study is a single-center, randomized, single-blind, 1:1 controlled trial. Intervention Measures Study participants were randomly assigned in a 1:1 ratio into two groups. Experimental group: Conventional laparoscopic myomectomy with the use of a single-channel uterine fibroid morcellation system for fragmentation and retrieval of the fibroids. Control group: Conventional laparoscopic myomectomy with the use of a multi-channel specimen retrieval bag and a conventional laparoscopic uterine fibroid morcellator for fragmentation and retrieval of the fibroids. Observation Indicators Primary observation indicator: Time required for fibroid fragmentation and retrieval (from the placement of the single-channel uterine fibroid morcellation system or the multi-channel specimen retrieval bag to complete removal from the abdominal cavity). Secondary observation indicators: Success rate of placement, intraoperative damage and leakage rate, gynecological surgeon satisfaction with the surgery, total weight of retrieved uterine fibroid fragments.

With the younger patients diagnosed with asymptomatic leiomyoma, delay in the reproductive age of women, the advancement of medical technology, and the rapid development of treatment methods, there are many choices between gynecologists, gynecologists and patients because of experience and knowledge. It is not easy to make the most favorable choice for patients. This study is mainly led by a committee composed of designers, doctors, nurses and patients, and based on clinical guidelines and evidence-based medicine. Co-operating with patients with asymptomatic small leiomyoma, we want to find the influencing factors of clinical decision-making, and to establish a patient decision aid tool. We use prospective trial to verify that the use of this tool can improve patients' decision-making efficacy and further improve patient-reported outcomes.
