abstract: OBJECTIVE
  To discuss the effect of electroacupuncture at Chengshan (BL 57) on postoperative pain of mixed hemorrhoids.
  
  
  METHODS
  One hundred and twenty cases with postoperative pain of mixed hemorrhoids were divided into an electroacupuncture group (60 cases) and a medication group (60 cases) randomly. The disperse-dense wave in frequency of 2Hz/100Hz at Chengshan (BL 57) were used in the electroacupuncture group. Its first treatment was in 30 min after the operation, and then it was given once a day after hip bath in the morning. 2 tablets of Naproxen Sunstained Release Capsule were taken in 30 min after operation in the medication group, and then it was taken 2 tablets a day before dressing change. After 4 times of treatment, evaluate the changing condition of Visual Analogue Scale (VAS) at 5 h, 24 h, 48 h and 72 h after operation.
  
  
  RESULTS
  The VAS at 5 h, 24 h, 48 h and 72 h after operation in the electroacupuncture group (6.78 +/- 2.12, 5.56 +/- 1.87, 4.34 +/- 2.23 and 3.15 +/- 2.11) were all lower than those in the medication group (7.56 +/- 2.01, 6.23 +/- 1.15, 5.57 +/- 2.21 and 4.34 +/- 2.12), and the difference was statistically significant (all P < 0.05).
  
  
  CONCLUSIONS
  Electroacupuncture at Chengshan (BL 57) can reduce the postoperative pain of mixed hemorrhoids.
