Optimal treatment options for uterine submucosal fibroids: Percutaneous microwave ablation versus transcervical resection of myoma

To compare the efficacy and safety of percutaneous microwave ablation (PMWA) and transcervical resection of myoma (TCRM) for submucosal fibroids.From January 2019 to January 2021, we conducted a randomized controlled study involving patients with symptomatic uterine submucosal fibroids. Questionnaires were also used to measure the uterine fibroid symptom (UFS) scores and quality of life (QoL) scores before and after treatment at 3, 6, and 12 months. Outcomes, adverse events, hemoglobin recovery, and submucosal fibroid volume of both groups were also compared. Operation time, amount of bleeding, hospital stay time, and occurrence of complications were compared in groups with fibroids of different lengths.Follow-up after surgery showed that UFS scores at 3, 6, and 12 months were significantly lower in each group, while QoL scores increased significantly. For fibroids less than 3 cm, surgical time was 34.2 ± 9.9 min, incidence of perioperative complications was 4.2%, and both decreased significantly, compared to the surgical time of the PMWA group (40.0 ± 8.1 min) and incidence of perioperative complications (24%; p < .05 for both). For uterine submucosal fibroids >5 cm, the operation time in the PMWA group was 92.7 ± 16.0 min, intraoperative bleeding volume was 22.7 ± 6.4 mL, and hospital stay was 2.7 ± 1.1 days, which were significantly less than the procedural time (107 ± 11.9 min), intraoperative bleeding loss (45.9 ± 12.8 mL), and length of hospital stay (5.0 ± 1.1 days) in the TCRM group. The differences were statistically significant (p < .05).PMWA and TCRM were both effective treatments for uterine submucosal fibroids. For fibroids shorter than 3 cm in length, especially pedicled submucosal fibroids, TCRM has absolute advantages; however, for uterine submucosal fibroids >5 cm, PMWA avoids perioperative complications, such as uterine perforation, water poisoning syndrome, and the need for repeat surgery, and is considered the preferred mode of treatment. Therefore, personalized treatment should be used for different patients with uterine submucosal fibroids.
