To compare the operative outcomes of patients undergoing either single-port or multiport laparoscopic hysterectomy (LH). Two hundred fifty-six women scheduled for LH for symptomatic myoma and/or adenomyosis from 8 tertiary teaching hospitals were randomized to single-port or multiport groups. Primary outcome was conversion and/or complication proportion of the planned procedure to determine whether the success proportion of the single-port approach was not inferior to that of the multiport approach. Secondary outcomes were postoperative pain and operative scar. Demographic parameters including age, body mass index, parity, and history of vaginal and cesarean delivery were comparable between the 2 groups. The primary outcome of a combined conversion and/or complication rate was similar between the single-port and multiport groups at 8% and 10.3%, respectively. Conversions were similar between the groups with 4% of single-port cases and .8% of multiport cases. Transfusions were the most frequent complication required in 4.0% of single-port cases and 7.9% of multiport cases, with no difference between the groups. Concerning secondary outcomes, postoperative pain score and patient and observer scar assessment were not different between the 2 groups. Although not a specific outcome measure, there was no difference between the groups in blood loss, operative time, and postoperative hospital stay. Single-port LH is not inferior to multiport LH in terms of conversion and/or complications rates, including transfusion. However, the single-port approach did not have any advantage over multiport LH with regard to pain or cosmetic outcomes. These findings were demonstrated by multi-institutional surgeons in Korea.
