Pregnancy can alter the rectus abdominis, but abdominoplasty can potentially correct these changes.
The aim of this study was to examine these muscle changes during pregnancy and to evaluate how effectively abdominoplasty with double folds of the rectus abdominis tightens the muscle.
Clinical data were obtained from nulliparous and pregnant patients who had undergone abdominoplasty with double folds of the rectus abdominis. Measurements were made of linea alba width, rectus abdominis width, thickness, and cross-sectional area, and abdominal circumference. Postoperative complications were also recorded. Patient satisfaction with the morphology of the rectus abdominis, both pre- and postsurgery, was assessed on a 5-point Likert scale.
The study included 400 women: 171 nulliparous, 106 with 1 pregnancy (Group 1), and 123 with 2 or more pregnancies (Group 2). Complete postoperative data were available for 32 patients (Group 3). Significant widening of the linea alba was found in Groups 1 and 2. The rectus abdominis width increased significantly in Group 1 but not in Group 2. Its thickness remained unchanged in Group 1 but decreased in Group 2, mirroring the pattern of its cross-sectional area. In Group 3, both the linea alba and rectus abdominis width decreased, while thickness and cross-sectional area increased. Satisfaction with muscle morphology improved significantly postsurgery, with no serious complications reported.
Pregnancy can cause the rectus abdominis muscle to separate, widening the linea alba and flattening the muscle. Abdominoplasty, which reinforces the muscle with double folds, effectively resolves this, resulting in high patient satisfaction and few complications.
怀孕会改变腹直肌，但腹壁成形术有可能纠正这些变化。
本研究的目的是检查孕期腹直肌的这些变化，并评估腹直肌双折腹壁成形术收紧肌肉的效果。
收集未生育及已生育且接受过腹直肌双折腹壁成形术患者的临床资料。测量白线宽度、腹直肌宽度、厚度、横截面积和腹围。记录术后并发症。采用5分李克特量表评估患者术前和术后对腹直肌形态的满意度。
该研究纳入400名女性：171名未生育女性，106名有1次妊娠经历的女性（第1组），以及123名有2次或更多次妊娠经历的女性（第2组）。32名患者（第3组）有完整的术后数据。第1组和第2组均发现白线明显增宽。第1组腹直肌宽度显著增加，而第2组未增加。第1组腹直肌厚度保持不变，而第2组腹直肌厚度减小，横截面积变化趋势与之相同。在第3组中，白线和腹直肌宽度均减小，而厚度和横截面积增加。术后患者对肌肉形态的满意度显著提高，未报告严重并发症。
怀孕可导致腹直肌分离，白线增宽，肌肉变平。通过双折加强肌肉的腹壁成形术可有效解决这一问题，患者满意度高，并发症少。
