Pediatric chronic appendicitis without surgical resection: A case study of endoscopic retrograde appendicitis therapy (ERAT)

Chronic appendicitis in pediatric patients is rare and challenging to diagnose, typically leading to surgical resection. However, Endoscopic Retrograde Appendicitis Therapy (ERAT) offers a minimally invasive alternative that preserves the appendix, maintaining its immune and digestive functions. A 13-year-old boy with a year-long history of worsening abdominal pain underwent ERAT. The procedure provided symptom relief and preserved the appendix. ERAT successfully treated the appendicitis while preserving the appendix, which plays crucial immune and digestive roles, especially in children. ERAT is a promising, non-surgical alternative for chronic appendicitis in pediatric patients, warranting further study. •Endoscopic Retrograde Appendicitis Therapy (ERAT) effectively treats chronic appendicitis.•ERAT preserves the appendix, reducing digestive dysfunctions and infection risks in children.•Novel minimally invasive technique provides accurate diagnosis through appendiceal irrigation.•Significant symptom relief achieved post-ERAT with normal follow-up MRI and blood tests.•ERAT is innovative in managing appendicitis while maintaining immune and digestive functions.
