To investigate the clinical effect of pre-pregnancy transumbilical single-port laparoscopic simplified cervical cerclage in the treatment of cervical incompetence, and discuss the safety and feasibility of the operation.

Medical records of 3 patients who underwent transumbilical single-port laparoscopic simplified cervical cerclage between Mar. 2022 and Nov. 2022 at Wuhai Maternal and Child Health Hospital were reviewed. Preoperative, intraoperative, and postoperative clinical data were analyzed.

All patients underwent a thorough pre-operative evaluation, showed clear indications for surgery and had a successful transumbilical single-port laparoscopic simplified cervical cerclage. The operation time of 3 patients was 68, 55 and 42 minutes respectively. The amount of bleeding in operation was less than 10 milliliters. Postoperative exhaust time were 15, 11 and 12 hours respectively. The visual analog scale pain score within 24 hours after surgery were 2, 1 and 1 respectively. The postoperative maximum body temperature was 36.6-36.8 ℃. No perioperative complications occurred in 3 patients. All were discharged successfully on the second day after surgery. The position of the cervical suture was located in the isthmus of the uterus according to transvaginal ultrasonography 1 week after the operation, and the cervical suture did not shift or fall off during the follow-up period. No poor wound healing or umbilical hernia occurred at the 3-month follow-up, and the cosmetic effect of umbilical suture was good. Patients were satisfied with the efficacy. Embryo transfer was performed postoperatively in 3 patients, all of whom were clinically pregnant. The current gestational weeks of the three pregnant women are all longer than the gestational weeks of the previous miscarriage.

For patients with cervical incompetence, transumbilical single-port laparoscopic simplified cervical cerclage surgery is feasible, but large-sample studies are still needed to verify.
