Long-term outcomes of single-port laparoscopic myomectomy using a modified suture technique

Objective: To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi's LM) and conventional 4-port LM. Methods: A retrospective study of patients who underwent Choi's LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with /=3 cm was detected. Results: The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8+/-1.5 cm vs. 7.0+/-1.6 cm; P=0.40). In Choi's LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi's LM (3.4+/-0.7 cm vs. 5.7+/-2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. Conclusion: Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi's LM were acceptable. Considering its usability, Choi's LM is feasible for the treatment of uterine leiomyoma.
