Abstract:Objective To explore the clinical effect of one-off radical resection and simple open drainage in the treatment of perianal abscess. Methods Totally 116 patients with perianal abscess admitted to Shaoxing Second Hospital between January and December 2017 were selected as study subjects. According to the random number table method, they were divided into an observation group and a control group, with 58 cases in each group. The patients of the observation group were treated with one-time radical surgery, while those of the control group were treated with open drainage. The clinical effect, hospitalization time, postoperative recurrence rate, postoperative complications, and mRNA and protein levels of IL-1α, IL-6, TNF-α, IL-4 and IL-10 were compared between the two groups. Results Compared to the control group, the effective rate was higher, the hospitalization time was shorter, the postoperative recurrence rate and the incidences of postoperative complications were lower in the observation group, and the differences were statistically significant (P < 0.05). On the 1st and 7th days after surgery, IL-1α, IL-6 and TNF-α protein levels in the observation group were significantly lower than those in the control group (P < 0.05). On the 7th day after surgery, IL-1α, IL-6 and TNF-α mRNA levels in the observation group were significantly lower than those in the control group (P < 0.05), while IL-4 and IL-10 mRNA levels in the observation group were significantly higher than those in the control group (P < 0.05). Conclusions Compared with the simple incision drainage, one-time radical resection can shorten the patient’s hospital stay, lower the cost of treatment, reduce the postoperative recurrence rate and the incidences of postoperative complications, and has higher total effective rate; it is worthy of clinical application and promotion.
