Methods We chose 56 patients suffered with II degree Bleeding Internal Hemorrhoids and treated by Doppler guided hemorrhoidal artery ligation(DGHAL).Up to the ligation point ,3groups were made and . A 3-months follow-up was given and the efficacy was recorded. Results The middle ligation group had the least complication and the best efficacy significantly.
