目的:主要目的是检测下段剖宫产术后发生峡部膨出的妇女人数。次要目标包括分析与峡部膨出相关的危险因素,并测量经阴道超声检查(TVS)和盐水输注超声宫腔造影(SIS)在诊断峡部膨出中的一致性。
方法:这项研究是在妇产科进行的,重点是进行了下段剖宫产(LSCS)的妇女。该研究旨在检测疤痕部位至少2毫米的压痕,被称为峡部膨出,在分娩后6周至6个月之间使用经阴道超声(TVS)和盐水灌注超声(SIS)。除了首要目标,该研究还评估了几个次要结果,如产妇合并症,闭合技术,和劳工细节。峡部膨出的评估遵循2019年修改的德尔菲共识方法。
结果:在我们的研究中,我们发现30%的研究人群有峡部膨出。我们还观察到,以前剖腹产的数量,产妇BMI,手术持续时间,先前CD瘢痕的特征与峡部膨出的发展显着相关。当我们比较诊断方法时,我们发现TVS和SIS对于临床上重要的峡部膨出参数具有相似的一致性限度.然而,我们注意到峡部与内部操作系统的长度和距离不同,我们通过BlandAltman的地块观察到的.
结论:我们的研究表明,多次剖腹产的妇女,有较高的产妇体重指数(BMI),并且经历了较长的手术时间,发生峡部膨出的风险明显较高。为了防止其发展,建议在可行的情况下促进剖腹产后阴道分娩,及早控制产妇肥胖,并为医疗专业人员提供足够的外科培训。此外,经阴道超声(TVS)是检测峡部膨出的有效方法,可以与注入盐水的超声检查(SIS)互换使用。
OBJECTIVE: The primary objective was to detect the number of women developing isthmocele following lower segment caesarean section. The secondary objectives included analysing the risk factors associated with developing isthmocele and measuring the agreement between Transvaginal Ultrasonography (TVS) and Saline infusion Sonohysterography (SIS) in diagnosing Isthmocele.
METHODS: This study was conducted in the Department of Obstetrics and Gynecology and focused on women who had undergone Lower Segment cesarean Section (LSCS). The study aimed to detect any indentation of at least 2 mm in the scar site, known as isthmocele, using Transvaginal Ultrasound (TVS) and Saline Infusion Sonography (SIS) between 6 weeks and 6 months after delivery. Along with the primary objective, the study also evaluated several secondary outcomes such as maternal comorbidities, closure techniques, and labor details. The evaluation of isthmocele followed the 2019 modified Delphi consensus approach.
RESULTS: In our study, we found that 30% of our study population had isthmocele. We also observed that the number of previous caesarean deliveries, maternal BMI, duration of surgery, and characteristics of the previous CD scar were significantly associated with the development of isthmocele. When we compared the diagnostic methods, we found that TVS and SIS had similar limits of agreement for clinically important isthmocele parameters. However, we noticed a difference in the length and distance of isthmocele from the internal os, which we observed through Bland Altman plots.
CONCLUSIONS: Our research has shown that women who have undergone multiple caesarean deliveries, have a higher maternal body mass index (BMI), and experienced longer surgery duration are at a significantly higher risk of developing isthmocele. To prevent its development, it is recommended to promote vaginal birth after caesarean delivery whenever feasible, manage maternal obesity early on, and provide adequate surgical training to medical professionals. Additionally, transvaginal ultrasound (TVS) is an effective method for detecting isthmocele and can be used interchangeably with saline-infused sonography (SIS).
