Anorectal Functional Outcomes Following Doppler-Guided Transanal Hemorrhoidal Dearterialization: Evidence from Vietnam

Introduction Doppler-guided transanal hemorrhoidal dearterialization (THD) was considered a less invasive and innovative method to treat hemorrhoidal disease, but it may impact the anal area during dearterialization and mucopexy. Thus, this study aimed to assess any changes in anorectal manometry of grade III and IV hemorrhoidal patients following THD treatment.
