  Abstract: Objective: This study aimed to compare the clinical efficacy of transumbilical single-port ,laparoscopic surgery (TU-LESS), conventional laparotomy, and conservative treatment, and to explore the clinical value of transumbilical singleport laparoscopy in the management of ovarian teratoma in pregnancy. Methods: Clinical data were collected from 143 pregnant patients with ovarian teratoma admitted to the Department of Gynecology, the Third Affiliated Hospital of Zhengzhou University between January 2019 and January 2025. Strict inclusion and exclusion criteria were applied. Patients were divided into three groups according to treatment modality: the single?site laparoscopic group (49 cases), the laparotomy group (60 cases), and the conservative treatment group (34 cases). Clinical data among the three groups were statistically analyzed. Results: There were no statistically significant differences in age, BMI, history of pelvic surgery, maximum diameter of teratoma, number of pregnancies, number of deliveries, and gestational age at surgery between the two surgical groups (P>0.05). The TU?LESS group was significantly superior to the laparotomy group in terms of intraoperative blood loss, postoperative decrease in hemoglobin, postoperative hospital stay, time to first flatus, postoperative PSAS scar score, and patient satisfaction with incision cosmetic outcome (P<0.05). No patients were lost to follow?up in any of the three groups, and all were followed up until the end of pregnancy. There was no statistically significant difference in the term delivery rate among the three groups (P>0.05). There was no statistically significant difference in the cesarean section rate between the two surgical groups (P>0.05). Con-clusion: Transumbilical single-port laparoscopic surgery is a safe and feasible primary treatment option for ovarian teratoma in pregnancy. It offers the distinct advantages of reduced intraoperative blood loss, minimal incision, and shorter hospital stays, without compromising maternal or fetal outcomes.
