Brief summary: 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.


Eligibility criteria: Inclusion Criteria:

Patients with uterine fibroids who meet the surgical indications. Patients aged 18 and above but below 45, who strongly request to preserve the uterus.

Patients planning to undergo laparoscopic myomectomy. Those who understand the purpose, procedures, potential risks of this trial, voluntarily participate in this study, and sign the informed consent form.

Exclusion Criteria:

Patients who cannot tolerate laparoscopic surgery due to their overall physical condition.

Patients with multiple fibroids have at least 4 fibroids, with the largest diameter of a single fibroid being equal to or greater than 10cm.

Patients who require surgical procedures other than laparoscopic myomectomy (excluding pelvic adhesion lysis, resection of mesosalpingeal cysts measuring less than 2cm, and superficial intraperitoneal lesions resection/electrocoagulation).

Preoperatively considering the possibility of uterine fibroid malignancy. Patients with preoperative unclear diagnosis, requiring differentiation from ovarian tumors.

Previously undergone lower abdominal or pelvic intraperitoneal surgery, or patients with severe pelvic or abdominal adhesions.

Presence of untreated infectious sexual diseases, including but not limited to vaginitis, cervical inflammatory diseases, and pelvic inflammatory diseases.

Patients who cannot understand the research protocol, cannot cooperate with the research and follow-up, and any other patients that researchers deem unsuitable for participation in this study.
