Key parameters analyzed included operative time, intraoperative blood loss, postoperative complications, hospital stay, postoperative first flatus time, preoperative and postoperative fetal heart rates, pregnancy outcomes, and postoperative visual analog scale (VAS) pain scores.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were no significant differences between the two groups in terms of baseline characteristics such as age, BMI, tumor diameter, number of deliveries, history of pelvic surgery, pregnancy duration, duration of abdominal pain, or preoperative fetal heart rate. The TU-LESS group had significantly shorter operative times compared to the laparotomy group. No significant differences were observed in tumor pathology, intraoperative blood loss, or number of tumor ruptures. The TU-LESS group experienced shorter hospital stays, fewer postoperative complications, and lower VAS scores at 48\u202fh post-operation compared to the laparotomy group. However, there were no significant differences between the groups in terms of time to first flatus, postoperative fetal heart rates, and VAS scores at 24\u202fh
