To compare the clinical efficacy of the new type of irrigation and aspiration therapy and vacuum sealing drainage in the treatment of high perianal abscess.

72 consecutive patients with high perianal abscess accepted to our department were randomized into the observation group and the control group, 36 cases in each group. The observation group underwent new type of irrigation and aspiration therapy and the control group underwent vacuum sealing drainage therapy. Preoperative, intraoperative and post-operative patient characteristics were evaluated.

Compared with control group, the incision length of observation group was significantly shorter [ (15.2±3.6) mm vs. (33.2±8.4) mm, t=-11.818, P=0.000], the operation time was significantly shorter too [ (14.2±2.6) min vs. (16.8±3.2) min, t=3.784, P=0.000], and the postoperative pain score was significantly lower [ (3.5±1.1) vs. (5.3±1.6), t=5.562, P=0.000], the wound healing time was significantly shorter [ (14.3±3.2) d vs. (18.2±4.8) d, t=-4.056, P=0.000]. While in wound healing rate (69.44% vs. 66.67%, χ²=0.064, P=0.800), fistula formation rate (22.22% vs. 25.00%, χ²=0.077, P=0.781), and abscess recurrence rate (5.56% vs. 8.33%, χ²=0.215, P=0.643), there were no significant differences between the two groups.

The new type of irrigation and aspiration therapy can reduce the surgical trauma, shorten the operative time, reduce the postoperative pain and shorten the wound healing time. The new type of irrigation and aspiration therapy is an effective method for minimally invasive treatment of high perianal abscess.
