Clinical observation on intersphincter drainage in treatment of perianal abscess
Objective: To compare the efficacy, safety and health economic indicators between intersphincteric drainage and simple incision drainage in the treatment of perianal abscess.,Methods,2,A total of 90 patients with perianal abscess were included and randomly divided into the study group and the control group, 45 cases in each group. The patients in the study group were treated with intersphincter drainage, and the patients in the control group were treated with simple incision drainage. Follow-up for 3 months after surgery, the formation rate of anal fistula, recurrence rate of perianal abscess and wound healing time were compared between the two groups. After surgery, the scores of anal pain, wound secretion exudation, fever and the first urination were evaluated. Three months after surgery, the scores of anal function assessment scale (Wexner) and anal appearance in the two groups were evaluated. The hospitalization time and cost were compared between the two groups.,Results,2,①The recurrence rate of perianal abscess was 0% in the study group and 6.67% in the control group, and there was no statistically significant difference on the recurrence rate between the two groups (,P,>,0.05). The formation rate of anal fistula was 22.2% in the study group and 48.9% in the control group, and the formation rate of anal fistula in the study group was lower than that in the control group (,P,<,0.01). The wound healing time of the study group was significantly shorter than that of the control group (,P,<,0.01). ②On the 3rd and 7th days after surgery, there was statistically significant difference on the visual analogue scale (VAS) score of anal pain between the two groups (,P,<,0.05, ,P,<,0.01), and the anal pain condition of the study group was superior to the control group. On the 3rd day after surgery, there was statistically significant difference on the score of wound secretion exudation between the two groups (,P,<,0.05), and the wound secretion exudation condition of the study group was superior to the control group. After surgery, there was no statistically significant difference on the score of fever between the two groups (,P,>,0.05). There was statistically significant difference on the score of postoperative first urination between the two groups (,P,<,0.05), and the postoperative first urination condition of the study group was superior to the control group. ③Three months after surgery, there were no statistically significant differences on the Wexner score and the anal appearance score between the two groups (,P,>,0.05). ④The hospitalization time of the study group was significantly shorter than that of the control group (,P,<,0.05), and the hospitalization cost of the study group was significantly less than that of the control group (,P,<,0.01).,Conclusion,2,Compared with simple incision drainage, intersphincter drainage has better therapeutic effect and safety in the treatment of perianal abscess, and its postoperative complications is mild, the health economic benefits are better.
