This book sheds new light on the anatomy, pathophysiology, clinical implications, and surgical interventions for diastasis of the rectus abdominis muscles. Diastasis recti is a prevalent condition, affecting approximately one-third of women post-delivery. Often dismissed as merely an aesthetic issue, recent research over the past 15 years has revealed its profound functional implications on core stability, lumbar support, pelvic floor function, and the overall integrity of the antero-lateral abdominal wall. The chapters cover topics such as the latest advancements in minimally invasive surgery—including laparoscopic, endoscopic, and robotic techniques—highlighting how these methods effectively address the functional issues associated with diastasis recti. Readers will discover insights into how this condition can be a significant risk factor for linea alba hernias and the recurrence of umbilical and median incisional hernias. Contributions from renowned experts provide a comprehensive analysis of current research and personal experiences, making this book an essential resource for understanding and treating diastasis recti.
