Clinical and Radiological Evaluation of Onlay Mesh Abdominoplasty in Obese Multiparous Patients with Moderate-to-Severe Rectus Diastasis.

Background: Women with multiple pregnancies often experience abdominal protrusion and/or a lax abdominal wall. Various open surgical techniques have been developed to address rectus diastasis in abdominoplasty, ranging from suture plication to mesh reinforcement. This study aims to compare the clinical and radiological changes between traditional abdominal plication and the addition of non-absorbable mesh for rectus muscle (RM) diastasis repair in terms of function, postoperative outcome, and recurrence.
