Objective: To evaluate the influence of various factors (myoma size, single vs multiple, location, weight) in Cesarean myomectomy (CM) and to demonstrate the additional advantage of CM by subgroup analysis.
Methods: Retrospective data was collected from 292 women with uterine myomas who had undergone Cesarean section (CS) in Hallym University Kangnam Sacred Heart Hospital between January 2007 and March 2019. Information about uterine myomas (type, diameter, weight, and number) was collected from the preoperative ultrasonography or the operation records. The types of myomas were divided into three categories including subserous & pedunculated (SS), intramural (IM), and submucous (SM). The weight of myomas was divided into three groups (<250g, 250-500g, ≥500g). The number of myomas was categorized as single or multiple. The diameter of the myomas was divided into three groups (<5cm, 5-10cm, ≥10cm).
Results: 119 of 292 had a CM and 173 of 292 had CS only(CSO). A statistically increase in postoperative hospitalization and operation time were observed in women undergoing myomectomy compared with those who had CSO. The estimated blood loss, differences of hemoglobin, postoperative transfusion rate of CM group were higher than those of CSO group. There was no difference in the incidence of intra/post-operative complication between two groups. No case of cesarean or postpartum hysterectomy was reported among the 119 parturient women who underwent CM. In subgroup analysis, the larger the myoma (both size and weight) increased the risk of bleeding that leads to transfusion. The estimated blood, differences of hemoglobin, postoperative transfusion were increased depending on the myoma size. There was a similar increasing trend for the myoma weights. A statistically increase in postoperative hospitalization was observed in women with larger myomas. However, there was no statistical difference in operative outcomes between three types of myoma (SS, IM, SM).
Conclusion: There are 2 factors that affect operation risk (especially Transfusion rate) including size and weight of myoma, but the number and type of myoma are unrelated to the prognosis of surgery. Although CM group needed more transfusion, the safety of CM is not inferior to that of CSO, considering the positive effects such as gynecological symptom relief and avoidance of next surgery.
