[Comparison of anorectal pressure after procedure for prolapse and hemorrhoids versus Doppler-guided hemorrhoidal artery ligation for grade III hemorrhoids].

Objective: To compare the long-term anorectal manometry of patients with grade III hemorrhoids treated by procedure for prolapse and hemorrhoids (PPH) or Doppler-guided hemorrhoidal artery ligation (DGHAL).

Methods: A total of 114 patients with grade III hemorrhoids in our department in 2010 were prospectively enrolled, and divided into PPH group (63 cases) and DGHAL group (51 cases) according to patient preference. Patients received anorectal pressure examination 2, 6, 12, 18 months after operation, including rectal resting pressure, anal resting pressure, maximal anal contractive pressure and length of high-pressure band.
