Study objective: To evaluate uterine scar features after laparoscopic myomectomy (LM) compared with myomectomy performed by laparoscopy initially and then completed with minilaparotomy (LAM).
Design: Prospective cohort study.
Setting: An academic center for advanced endoscopic gynecologic surgery.
Patients: Sixty-nine symptomatic women who underwent myomectomy between July and December 2018.
Intervention: Patients underwent LM or LAM and 3-month follow-up ultrasonography.
Measurements and main results: Forty-four patients underwent LM and 25 underwent LAM. Demographic data, intraoperative parameters, and postoperative outcomes were collected. Two-dimensional color Doppler ultrasound was done at a 3-month follow-up to evaluate myomectomy scar features, myometrial thickness, and the presence of and vascularity of a heterogeneous mass. These features were compared with those of the intact myometrium on the opposite wall of the patient's uterus. The 2 groups had similar demographic characteristics, and there were no significant between-group differences in the number, maximum diameter, type, or location of myomas. The mean myometrial thickness at the scar site was 18.9 ± 3.22 mm in the LM group and 19.7 ± 3.50 mm in the LAM group, with no significant difference between the 2 groups. There was no meaningful difference in vascularity between the scar and normal myometrium. Heterogeneous masses were detected in 23% of patients in the LM group and in 24% of those in the LAM group. Other than mean operative time (207 minutes for LM vs 150 minutes for LAM; p < .001) and mean postoperative reduction in hemoglobin (1.77 mg/dL for LM vs 2.35 mg/dL for LAM; p = .023), there were no other statistical differences between the 2 groups. One patient in the LM group experienced a bowel injury resulting from morcellation.
Conclusion: There were no differences in myometrial scar features after LM compared with after LAM, implying effective suturing via both approaches.
