Endoscopic Retrograde Appendicitis Therapy - a Pilot Study

Intervention Type: Procedure
Study Type: Interventional
Sponsors: Chinese University of Hong Kong
Participants: 20
This is a prospective pilot study on the efficacy of endoscopic therapy for adult uncomplicated acute appendicitis. In recent years, antibiotics treatment has been a new alternative approach to surgical appendicectomy for acute appendicitis, however, there is a risk of failed antibiotics treatment and chance of recurrent appendicitis. Endoscopic therapy of acute appendicitis (ERAT) has been recently described that involves colonoscopic insertion of plastic stent and removal of appendicolith. The investigators conduct this pilot study to investigate the feasibility, technical and clinical success rate of endoscopic retrograde appendicitis therapy among adult patients with uncomplicated acute appendicitis. 20 patients would be recruited for the pilot study.
