Abstract:

Objective To investigate the efficacy of treatment of perianal horseshoe abscess via the approach between the sphincter internal and the sphincter externus. Methods From December 2014 to December 2019, 50 cases of horseshoe perianal abscess in gastrointestinal surgery of Jiangmen Central Hospital were selected. According to the random number table, patients with perianal horseshoe abscess were randomly divided into two groups, the experimental group (by the approach between the sphincter

internal and the sphincter externus) 25 cases and the control group (by classical approach) 25 cases. The operation time, intraoperative blood loss, duration of the postoperative pain, hospital stay, healing time of surgical incision, anal function, anal morphology, recurrence rate, anal fistula rate and complex anal fistula rate of two groups were recorded and analyzed. Results There were statistical differences in the terms of operation time, duration of the postoperative pain, healing time of surgical incision, anal function, anal morphology anal fistula rate and complex anal fistula rate, experiment group is much better

than that of the control group (P<0.05); However, there were no statistical differences in the terms of intraoperative blood loss, hospital stay and recurrence rate between the two groups (P>0.05). Conclusion Compared with the traditional approach, it has good clinical effect to treat horseshoe perianal abscess through the approach between the sphincter internal and the sphincter externus.
