【摘要】 目的：剖宫产率逐年上升，而剖宫产切口瘢痕缺陷的治疗具有较大挑战性。本研究旨在评估术前磁共振成像技术对于腹腔镜手术治疗剖宫产切口瘢痕缺陷相关异常子宫出血患者的临床价值并分析相关影响因素。方法：选择2018年至2022年在中南大学湘雅三医院妇科接受腹腔镜手术治疗剖宫产切口瘢痕缺陷相关异常子宫出血的患者共计57例，进行回顾性队列分析。将57例患者根据腹腔镜手术治疗剖宫产切口瘢痕缺陷相关异常子宫出血的术后临床治愈情况分为临床治愈组(n=28,49.1%)及非临床治愈组(n=29,50.9%)。对所有的受试者进行术后3个月的随访调查，通过logistic回归分析探讨患者的年龄、临床症状、孕产史、剖宫产史等基本临床信息、术前磁共振成像参数以及术后月经情况等与腹腔镜手术治疗剖宫产切口瘢痕缺陷相关异常子宫出血的临床治愈率的相关性。结果：2组患者的年龄、前次剖宫产年龄、怀孕次数、前次剖宫产时间、腹腔镜术前T2信号磁共振评估的子宫位置、缺陷长度、缺陷宽度、缺陷残余肌层厚度、缺陷邻近子宫肌层厚度及缺陷距宫颈外口距离等参数的差异均无统计学意义(均P>0.05)。患者的异常子宫出血症状出现时间(P=0.036,OR=1.019,95%CI 1.002～1.038)和术前磁共振成像的缺陷深度(P=0.010,OR=5.793,95%CI 1.635～25.210)是影响临床治愈率的危险因素。结论：患者异常子宫出血症状出现时间及术前磁共振评估的缺陷深度是腹腔镜手术治疗剖宫产切口瘢痕缺陷相关异常子宫出血临床治愈的影响因素，术前磁共振对于判断本病预后具有一定的临床意义。更多还原

【Abstract】 Objective: As the cesarean section rate increases year by year, the treatment of previous cesarean scar defects(PCSD) poses a significant challenge. This study aims to evaluate the clinical value of preoperative magnetic resonance imaging(MRI) technology and analyze relevant influencing factors for patients with abnormal uterine bleeding(AUB) associated with cesarean scar defects who underwent laparoscopic surgery.Methods: A retrospective cohort analysis was performed on women who underwent laparoscopic surgery for PCSD-related AUB at the Department of Gynecology, the Third Xiangya Hospital of Central South University from 2018 to 2022. A total of 57 patients who underwent laparoscopic surgery for the treatment of AUB associated with PCSD were divided into 2 groups based on their postoperative clinical cure status: The clinically-cured group(n=28, 49.1%) and the non-clinically-cured group(n=29, 50.9%). After a postoperative follow-up period of 3 months for all participants, logistic regression analysis was conducted to explore the correlation between the clinical cure rate of AUB associated with cesarean scar defects treated by laparoscopic surgery and various factors. These factors included patient age, clinical symptoms, obstetric history, history of cesarean section, basic clinical information, preoperative MRI parameters, and postoperative menstrual conditions.Results: There were no significant differences in many aspects, including the patient’s age at the time of previous cesarean section, number of pregnancy, time since the previous cesarean section, the uterus position assessed by preoperative T2 signal MRI, defect length,defect width, residual muscle layer thickness, adjacent uterine muscle layer thickness, and distance from the defect to the external cervical os between the 2 groups(all P>0.05). However, the time of onset of AUB symptoms(P=0.036, OR=1.019, 95% CI 1.002 to 1.038) and the depth of the defect on the preoperative MRI(P=0.010, OR=5.793, 95% CI 1.635 to 25.210) were identified as risk factors affecting the clinical cure rate.Conclusion: The time of onset of AUB symptoms and the depth of the defect on preoperative MRI are risk factors that influence the clinical cure rate of laparoscopic surgery for the treatment of AUB associated with PCSD, which could be helpful for evaluating the prognosis of disease.更多还原
