To observe the number, distribution and mean blood flow velocity of superior hemorrhoid artery branches before and after operation in patients with mixed hemorrhoids.

Eighty cases with mixed hemorrhoids of Stage Ⅲ~Ⅳ were randomly divided into two groups. The experimental group was treated with ligation of hemorrhoid artery and anal pad suspension, while the control group was treated with Milligan-Morgan procedure, the number, location and average blood flow velocity of the superior hemorrhoid artery were measured by high-frequency color doppler ultrasound before and after operation.

The experimental group and control group hemorrhoid artery branch number of preoperative compared with heals all differences, two groups have statistical significance (Z=-10.042, -7.488; P<0.05) when patients heal hemorrhoid artery branch number differences statistically significant (Z=-3.500, P<0.05), the blood flow velocity of the experimental group was significantly higher than that of the healing group (t=4.086, P<0.05), there was no significant difference in blood flow velocity between the control group and the control group (t=1.385, P>0.05); Preoperative hemorrhoid artery distribution points were mainly 3, 7 and 11 points in both groups. When healing, the hemorrhoid artery distribution points in the experimental group were mainly 3, 5, 7 and 9 points, while the hemorrhoid artery distribution points in the control group were still mainly 3, 7 and 11 points. The cure rate of both groups was 100%, the healing time of the experimental group was better than that of the control group (t=-3.246, P<0.05).

Ultrasound guided hemorrhoid artery ligation anal cushion suspension can really precise hemorrhoid ligation of artery, changed the hemorrhoid artery branch number and blood flow velocity, has significant curative effect on bleeding hemorrhoids, and a short healing time of potential advantages, main point of the distribution of artery change if there is a correlation with the prognosis, is worth further research.
