An analysis of the surgical outcomes of laparoendoscopic single-site myomectomy and multi-port laparoscopic myomectomy

BACKGROUND: This study sought to compare the surgical results of patients undergoing a laparoendoscopic single-site myomectomy (LESS-M) and a conventional laparoscopic myomectomy (CLM) at our hospital. METHODS: The basic data of 233 patients undergoing LESS-M and 233 patients undergoing CLM at the Obstetrics and Gynecology Hospital Affiliated to Fudan University were collected from January 2018 to January 2020, and the results of the operations were compared by evaluating a number of factors, including operation time, intraoperative bleeding, postoperative fever, and postoperative maximum body temperature. RESULTS: The operation times of the LESS-M and CLM groups were 83.9±33.4 and 75.2±26.7 min, respectively; the difference between the groups was statistically significant. The surgical blood loss of the LESS-M group was 86.1±76.9 mL, and that of the CLM group was 83.8±79.9 mL (P>0.05). When the diameter of a fibroid was ≥8 cm, a fibroid was located in the posterior wall or the number of fibroids was ≥4, the operation time of the CLM group was shorter than that of the LESS-M group. When the diameter of a fibroid was ≥8 cm, the blood loss of the CLM group was less than that of the LESS-M group. CONCLUSIONS: LESS-M is safe and feasible. If the diameter of a fibroid is ≥8 cm, the fibroid is located in the posterior wall, or the number of fibroids is ≥4, the utility of single-port surgery should be carefully considered.
