Endoscopic Retrograde Appendicitis Therapy in Subacute Appendicitis With Abscess: A Comprehensive Case Study and Innovative Insights.

This case report explores the feasibility and efficacy of endoscopic retrograde appendicitis therapy (ERAT) in treating a 42-year-old female with subacute appendicitis complicated by an abscess. The patient, initially presenting with abdominal pain, underwent an endoscopic intervention involving drainage, irrigation, and stent placement in the appendix. The study discusses the patient's successful outcome, emphasizing the role of ERAT in managing complicated appendicitis with abscesses. The report outlines the case presentation with the initial misdiagnosis of cecal intussusception. The endoscopic procedure involved identifying a partially prolapsed appendix, spontaneous drainage of purulent discharge, and subsequent stent placement to facilitate drainage while awaiting definitive surgery. The patient's positive response to ERAT was marked by pain reduction and a follow-up CT scan confirming the absence of an abscess and a normal appendix. The case report asserts that ERAT emerges as a promising alternative to immediate appendectomy for patients with subacute appendicitis complicated by abscesses, enhancing symptom relief and reducing major adverse events.
