“…Similarly, in the study of Sizzi et al [5], operative time was most significantly correlated with the dominant myoma diameter, followed by the number of removed myomas, but not with the myoma localization. Hsu et al [28] observed a strong correlation between sonographically estimated myoma weight and operation time. Torng et al [29] suggested that operative experience is a major factor influencing operative time, regardless of the weight or number of removed myomas.…”

IntroductionLaparoscopic myomectomy (LM) can be associated with significant bleeding.AimTo identify factors influencing the postoperative hemoglobin (Hb) drop after LM.Material and methodsThis is a retrospective, single-center study. We evaluated data of 150 consecutive patients undergoing LM due to intramural myomas between 2010 and 2015.ResultsThe median age of the patients was 37 (23–53) years. The mean diameter of the largest myoma was 5.7 ±2.3 (1.5–12) cm. The mean surgical time was 83 ±38 (35–299) min. The median number of sutures was 3 (1–11). The mean postoperative Hb drop was 1.6 ±1.2 (0–6) g/dl, and the mean estimated blood loss was 261 ±159 (50–1700) ml. In the univariate analysis, the postoperative Hb drop correlated with the duration of surgery (p < 0.001), diameter of the largest myoma (p < 0.001), cumulative myoma weight (p < 0.001), and number of sutures (p < 0.001), but not with patients’ age or number of intramural myomas. In the multivariable analysis, the surgical time (β = 0.395, p < 0.001), diameter of the largest myoma (β = 0.292, p = 0.03) and preoperative Hb concentration (β = 0.299, p < 0.001) predicted the postoperative Hb change.ConclusionsSurgical time and dominant myoma diameter are independent predictors of the postoperative Hb drop after LM.

“…Instead, in our study we included patients with only one symptomatic uterine myoma, with maximal diameter B6 cm and C4 cm estimated by US, and we excluded patients with subserosal, submucosal, or intraligamentous myoma/s. Myoma dimensions and location are important factors, which may significantly influence operative time [55], thus these features must be considered and analyzed to avoid bias.…”

“…The weight of the uterus and myomas was then converted to mass units (g) by multiplying the assumed constant density for adipose tissue–free smooth muscle (1.04 g/cm 3 ). 8 The uterine and myomas weight calculated was then recorded as “ultrasound estimated uterine weight.”…”

Background and Objectives: Laparoscopic hysterectomy for a large barrel-shaped uterus is difficult. We assessed the feasibility of single-port laparoscopic hysterectomy in a large barrel-shaped uterus after gonadotropin-releasing hormone agonist (GnRHa). Methods: We retrospectively reviewed 39 patients with a large barrel-shaped uterus who were treated with GnRHa (leuprolide acetate) before single-port laparoscopic hysterectomy. During the same period, 134 patients without GnRHa pretreatment were included as control subjects. Results: Patients with GnRHa treatment had an average increase in hemoglobin of 3.0 mg/dL and a decrease in uterine weight of 330.9 g (40.1%). Ancillary ports were required in 2 patients in the treatment group and none in the control group. There were no differences in uterine weights, operative time, and estimated blood loss in the 2 groups of patients. The estimated average operative time was shortened by 34 min after GnRHa treatment. However, bladder and ureter injuries were marginally higher (10.3% versus 2.2%) and days of hospital stay (3.7 versus 3.1) were significantly longer in the treatment group compared with controls. Complication rates were correlated with previous operative history, pelvic adhesion, and larger uterine weight but not with GnRHa treatment and operative sequence. Conclusions: GnRHa pretreatment in patients with a large barrel-shaped uterus during SPH is feasible with shortened operative time. However, the higher complication rates in these patients suggest that a weight-reduced barrel-shaped uterus that is achieved with GnRHa treatment could still be difficult and should be handled in cautious.

Prediction of operation time for laparoscopic myomectomy by ultrasound measurements

Abstract: Operation time was significantly related to the myoma weight measured by ultrasound. The ultrasound-derived prediction equation is valid and reliable in predicting operation time for LM.
