Appendicitis is the common acute abdomen in children, and its diagnosis and treatment are of great significant in clinical practice. Endoscopic retrograde appendicitis therapy (ERAT) is a minimally invasive treatment method for appendicitis that does not require appendectomy and has been widely used in the treatment of appendicitis in children. This paper summarizes the research progress on ERAT in the treatment of pediatric appendicitis in recent years, in order to better understand the iterative development of ERAT and its application in pediatric appendicitis, and provide reference for the formulation of clinical therapeutic regimen for this disease.
