Why do some surgeons opt to approximate the rectus abdominis muscles after surgery?

Surgeons often choose to approximate the rectus abdominis muscles after surgery primarily to prevent rectus diastasis. This condition involves the separation of the abdominal muscles, which can occur after surgical procedures or after significant changes in body weight, such as pregnancy. By reapproximating the muscles, the surgeon helps maintain the anatomical integrity of the abdominal wall, reducing the risk of muscle separation during the patient's recovery.

Approximating the rectus muscles not only prevents diastasis but also assists in maintaining core stability and preserving the function of the abdominal wall. This decision ultimately has implications for the patient’s long-term functional outcomes, contributing to a better overall recovery experience. In contrast, while enhanced muscle strength, limited postoperative pain, and faster recovery are benefits that may arise from a well-executed surgical approach, they are not the primary rationale for muscle approximation in this context.
