Open Reconstruction for Massive Abdominal Wall Defect Following Radical Resection of Recurrent Endometriosis: A Novel Retromuscular-Onlay Dual-Mesh Technique

Abdominal wall endometriosis (AWE), often post-cesarean, can cause massive abdominal wall defects following lesion resection. This report details a novel open technique for recurrent massive AWE in a 32-year-old female involving radical excision with at least 1cm margins and dual-mesh repair with pre- and post-rectus abdominis placement alongside stratified drainage. The operation went smoothly, the patient was discharged on day 6, pathology confirmed the diagnosis, and short-term follow-up showed excellent outcome without complications, demonstrating a safe and effective reconstructive strategy.
