Clinical Observation Of Segmental Linear Incision And Blind End Hanging Line For Abscess Of Ischiorectal Fossa

Objective:In this study,the randomized controlled trial was used to observe the clinical efficacy of segmental linear incision and blind end thread-drawing drainage of abscess in ischiorectal fossa,so as to provide reference and method for clinical surgery to treat perianal abscess.Methods:In this study,according to the principle of random control,64 patients who met the relevant criteria of sciatic-rectal abscess were divided into an observation group and a control group,32 cases in each group.The operation method adopted in the observation group was segmental linear incision of ischiocrectal abscess and blind end thread-drawing drainage,while the operation method adopted in the control group was fenestration and mouth-to-mouth drainage of ischiocrectal abscess and blind end thread-drawing.The clinical curative effect,operation time,wound area,wound healing rate,wound healing time,postoperative complications,anal function and postoperative recurrence rate of the two groups were observed and recorded,and the collected statistical data were analyzed and compared by SPSS26.0 statistical software.Results:During the study,there were two cases of dropping out,one in each group.A total of 62 cases were actually observed,including 31 cases in the observation group and 31 cases in the control group.The statistical study showed that the general data(gender,age,and course of disease)of the observation group and the control group were not statistically significant(P>0.05),indicating that the two groups were comparable.The differences between the two groups in the appearance time of epithelial tissue,wound healing time,wound area on the 1st and 15 th d after operation,wound healing rate on the 15 th d after operation,wound healing on the 28 th and 30 th d after operation,anal sulcus and surgical scar were statistically significant(P<0.05).For the comparison of clinical effects,one month after operation:P < 0.05,the difference was statistically significant;Six months after surgery:P>0.05,the difference was not statistically significant.There was no significant difference in operation time and postoperative anal pain between the two groups(P>0.05).Follow-up comparison:no anal incontinence,recurrence,residual anal fistula or adverse events were observed between the two groups.Conclusion:Segmental linear incision with blind end thread-drawing drainage and fenestration with counterpart drainage with blind end thread-drawing can both effectively treat ischiorectal fossa abscess.However,segmental linear incision with blind end thread-drawing drainage has advantages in accelerating wound healing process,beautifying and minimally invasive,etc.thus it can be used as an alternative method for surgical treatment of patients with ischiorectal fossa abscess and is worthy of being used for reference.
