During the same period, we also had 10 cases of conventional laparoscopic myomectomy (using three
trocars) and 10 cases of non-virgin single-port laparoscopic myomectomy (i.e., using uterine manipulator).
We compare them in Table 4. The age was younger in those two groups (50.10 ± 7.79 vs. 42.6 ± 6.02 and
42.8 ± 4.69), and the maximum diameter of myoma was smaller in them (11.24 ± 3.27 cm vs. 7.30 ± 2.06 cm
and 8.71 ± 2.05 cm). However, in BMI, number of myomas removed, operation time, blood loss, and
VAS score when arriving at the ward and 24 h later, there were no significant differences among the three
groups.

We compared our data to previous published literature concerning single-port laparoscopic myomectomy,
and the results are shown in Table 5.
