Objectives:
To study the operative outcomes of single-port laparoscopic hysterectomy in uteri greater than 500 g, using either laparoscopic assisted vaginal hysterectomy (LAVH) or laparoscopic supracervical hysterectomy (LSH).
Materials And Methods:
78 patients were included in a single institute by a single surgeon from March, 2013 to January, 2018.
Results:
The median uterine weight was 686.5 g. Larger uterine weight was correlated with longer operative time and greater estimated blood loss. Two types of operations were performed: LAVH (n = 55) or LSH (n = 23). There were no differences in operative time (150.2 ± 45.1 vs. 158.6 ± 82.1, P = 0.66) and estimated blood loss (365.8 ± 298.5 vs. 356.5 ± 46.6, ml, P = 0.94) between LAVH and LSH. However, patients in LAVH had more excess blood loss (>500 mL) compared with LSH (32.7% vs. 21.7%, P = 0.42). In the later study period, the operative time was shorter and complication rates were lower. Such differences were especially significant in the LAVH group. By multiple regression analysis, operative time was independently correlated with age, body mass index, estimated blood loss and uterine weight in LAVH. The correlation between operative time and uterine weight in LSH was attenuated by estimated blood loss. Estimated blood loss was the dominant factor correlated with longer operative time in LSH.
Conclusions:
Both LAVH and LSH could be feasible in uteri greater than 500 g. LSH appeared to have less complication and less blood loss than LAVH. Operative time was correlated significantly with bleeding amount. Therefore, better bleeding control and surgical experience were warrants for single-port laparoscopic hysterectomy in uteri greater than 500 g.
