Intraoperative ultrasound-assisted enucleation of residual fibroids following laparoscopic myomectomy.

AIM: To investigate if intraoperative ultrasounds by laparoscopic and transvaginal ultrasonography (LUS and TVS) could improve enucleating the residual fibroids following laparoscopic myomectomy (LM).

METHODS: From March to December 2016, 78 women with uterine fibroids underwent LM, LUS and TVS were applied to detect residual fibroids and to guide surgeons to enucleate them after the visible fibroids were removed during LM operation.

RESULTS: The total number of residual fibroids found by LUS was 140, and the total number found by TVS was 127 following LM (P = 0.03). LUS is statistically superior to TVS in the detection of residual fibroids in the anterior wall (P = 0.004), in the detection of intramural fibroids (P = 0.002), and in the detection of fibroids with a diameter ranging from 0.5 to 1 cm (P = 0.002). According to the total number of enucleated fibroids by LM, patients were divided into three groups (Group 1: 2 to 4, Group 2: 5 to 7 and Group 3: ≥8 fibroid counts). The percentages of patients in each group with residual fibroids at the end of surgery were 22.2%, 51.9% and 66.7% respectively.

CONCLUSIONS: Both LUS and TVS are beneficial to surgical treatment of fibroids by assisting enucleation of residual fibroids following LM, while LUS is more effective in localizing residual fibroids than TVS.
