Abstract: Abdominal rectus diastasis is common in postpartum women and obese people, with clinical manifestations of midline abdominal bulge and lower back pain. Severe cases may affect the function of abdominal wall muscle groups, which cause a series of physiological dysfunction. There are few studies on the diagnosis and optimal management of abdominal rectus diastasis, especially on its surgical indications, and no uniform conclusion is achieved. The authors comprehensively analyze the research progress at home and abroad, exploring the etiology, diagnosis, treatment options and surgical indications of abdominal rectus diastasis, in order to provide references for clinical practice.
