摘要

目的：利用盆底超声评价不同分娩方式（阴道分娩和剖宫产）对双胎妊娠妇女肛提肌（LAM）和盆腔器官脱垂（POP）的影响。方法：84例双胎妊娠孕妇随机分为阴道分娩组和剖宫产组。结果：剖宫产术中LAM损伤发生率明显降低。剖宫产组的静息状态和最大Valsalva动作状态LAM裂面积较小，而LAM面积差异较大（Δ）。LAM损伤诊断POP的敏感性为0.667。基于静息状态LAM裂隙面积诊断POP的最佳截止值为15.37。结论：盆底超声评估LAM状态对产后6个月POP的发生有一定的预测价值。

Assessment of Different Delivery Modes on Levator Ani Muscle and Pelvic Organ Prolapse in Twin Pregnancy Using Pelvic Floor Ultrasound: A Prospective Randomized Study.

Objectives: To assess the impact of different modes of delivery, vaginal delivery, and cesarean section, on the levator ani muscle (LAM) and pelvic organ prolapse (POP) in women with twin pregnancies using pelvic floor ultrasound.

Methods: 84 pregnant women with twin pregnancies were randomized either into the vaginal delivery group or the cesarean section group.

Results: The incidence of LAM injury was significantly lower in the cesarean section. The resting state and maximum Valsalva maneuver state LAM cleft areas were smaller in the cesarean section group, while the difference (Δ) in LAM area was larger. The sensitivity of LAM injury in diagnosing POP was 0.667. The optimal cutoff value for diagnosing POP based on the resting state LAM cleft area was determined to be 15.37.

Conclusion: Pelvic floor ultrasound assessment of LAM status demonstrated some predictive value for the occurrence of POP at 6 months postpartum.

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
