Analysis of risk factors for postoperative bleeding and recurrence after laparoscopic myomectomy in patients with uterine fibroids: a retrospective cohort study

BACKGROUND: In Asia, the incidence of uterine fibroids (UFs) in women is as high as 1.278%. However, there are few analyses of the prevalence and independent risk factors for bleeding and recurrence after laparoscopic myomectomy (LM). This study aimed to analyze the clinical characteristics of patients with UF and identify the independent risk factors for postoperative bleeding and recurrence after LM, so as to provide a reference basis for improving the quality of life of patients. METHODS: Based on our exclusion and inclusion criteria, we retrospectively analyzed a total of 621 patients who developed UF from April 2018 to June 2021. The t-test, analysis of variance (ANOVA), and chi-square test were used to analyze the relationship between the clinical characteristics of the patients and postoperative bleeding as well as recurrence. Binary logistic regression was used to analyze the independent risk factors for the occurrence of postoperative bleeding and fibroid recurrence in patients. RESULTS: The rates of postoperative bleeding and recurrence after LM for uterine fibroids were 4.5% and 7.1%, respectively. Binary logistic regression analysis showed that fibroid size [odds ratio (OR) =5.502, P=0.003], maximum fibroid type (OR =0.293, P=0.048), pathological type (OR =3.673, P=0.013), preoperative prothrombin time level (OR =1.340, P=0.003), preoperative hemoglobin level (OR =0.227, P=0.036), surgery time (OR =1.066, P=0.022), intraoperative bleeding (OR =1.145, P=0.007), and postoperative infection (OR =9.540, P=0.010) were independent risk factors for postoperative bleeding; meanwhile, body mass index (BMI) (OR =1.268, P=0.001), age of menarche (OR =0.780, P=0.013), fibroid size (OR =4.519, P=0.000), fibroid number (OR =2.381, P=0.033), maximum fibroid type (OR =0.229, P=0.001), pathological type (OR =2.963, P=0.008), preoperative delivery (OR =3.822, P=0.003), preoperative C-reactive protein (CRP) level (OR =1.162, P=0.005), intraoperative ultrasonography (OR =0.271, P=0.002), postoperative gonadotropin-releasing hormone agonist treatment (OR =2.407, P=0.029), and postoperative infection (OR =7.402, P=0.005) were independent risk factors for recurrence. CONCLUSIONS: At present, there is still a high probability of postoperative bleeding and recurrence after LM for UF. Clinical work should pay close attention to clinical features. Adequate preoperative examination to improve surgical precision, and strengthen postoperative care and education, thus reducing the probability of postoperative bleeding and recurrence in patients.
