Abstract：
OBJECTIVE: Split abdominal wall muscle flap (SAWMF) is a technique to repair large defects in congenital diaphragmatic hernia (CDH). A possible objection to this intervention could be any associated abdominal muscle weakness. Our aim is to analyze the evolution of this abdominal muscle wall weakness.
METHODS: Retrospective review of CDH repair by SAWMF (internal oblique muscle and transverse) from 2004 to 2023 focusing on the evolution of muscle wall weakness.
RESULTS: Eighteen neonates of 148 CDH patients (12,1%) were repaired using SAWMF. Mean gestational age and birth weight were 35.7 ± 3.5 weeks and 2587 ± 816 g. Mean lung-to-head ratio was 1.49 ± 0.28 and 78% liver-up. Seven patients (38%) were prenatally treated by tracheal occlusion. Ninety-four percent of the flaps were used for primary repair and one to repair a recurrence. One patient (5.6%) experienced recurrence. Abdominal muscle wall weakness was present in the form of a bulge. Resolution of weakness at 1, 2 and 3 years was 67%, 89% and 94%, respectively. No patient required treatment for weakness or died.
CONCLUSIONS: Abdominal muscular weakness after a split abdominal wall muscle flap repair is not a limitation for its realization since it is asymptomatic and presents a prompt spontaneous resolution.
METHODS: IV.

摘要：
目的：裂开腹壁肌皮瓣（SAWMF）是一种修复先天性膈疝（CDH）大型缺损的技术。对这种干预的可能反对意见可能是任何相关的腹部肌肉无力。我们的目的是分析这种腹肌壁无力的演变。
方法：回顾性回顾了2004年至2023年通过SAWMF（内斜肌和横肌）进行的CDH修复，重点是肌壁无力的演变。
结果：使用SAWMF修复了148例CDH患者中的18例新生儿（12,1％）。平均胎龄和出生体重为35.7±3.5周和2587±816g。平均肺头比为1.49±0.28，肝脏上升率为78％。7例患者（38％）在产前接受气管闭塞治疗。94％的皮瓣用于初次修复，一个用于修复复发。1例（5.6%）复发。腹部肌壁无力以凸起的形式存在。1年，2年和3年的弱点分辨率为67％，89%和94%，分别。没有患者因虚弱而需要治疗或死亡。
结论：腹壁肌皮瓣裂开修复后的腹肌无力对其实现没有限制，因为它是无症状的，并表现出迅速的自发消退。
