Battle of the hemorrhoid surgeries: open vs. THD – which offers better relief?
NCT ID NCT06420986
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two surgical treatments for grade III hemorrhoids: open hemorrhoidectomy and transanal hemorrhoidal desarterialization (THD). Fifty adults were randomly assigned to one of the two procedures and tracked for a year. The main goal was to see which surgery better reduced symptoms like pain, bleeding, and itching. Participants filled out symptom forms before surgery and at follow-up visits.
