Clinical Observation On The Therapeutic Effect Of Improved Retained Anal Sphincter Arc-shaped Bridging Drainage In The Treatment Of Multiple-space Perianal Abscesses

Background and Purpose of the Study:Multiple-cavity perianal abscesses are common in colorectal surgery and difficult to treat.To date,there is no consensus on the ideal surgical technique for this condition.The traditional approach involves multiple incisions with a radial drainage technique,which can lead to problems such as large postoperative wounds,poor drainage of pus cavities,slow healing,and a high risk of recurrence or false healing.Therefore,exploring more effective and safer surgical methods in clinical practice has been a hot topic in this field.This study aims to observe the clinical efficacy of "improved retained anal sphincter arc-shaped bridging drainage" versus "radial multiple incision drainage" in the treatment of multiple-cavity perianal abscesses by improving traditional techniques,in order to provide safer and more effective surgical procedures and treatment methods for the management of this condition..Research Methods:This study adopted a randomized controlled clinical trial method.Based on the diagnostic inclusion criteria,106 patients with multiple-cavity perianal abscesses in the Department of Integrated Traditional Chinese and Western Medicine at the First Affiliated Hospital of Chengdu Medical College were randomly divided into an observation group and a control group,with 53 patients in each group.The observation group underwent an improved retained anal sphincter arc-shaped bridging drainage procedure,while the control group underwent a radial multiple incision drainage procedure.General information such as gender and age of the two groups,operation time,intraoperative bleeding volume,postoperative pain score,wound healing time,preoperative and postoperative anorectal manometry indices,postoperative scar area,anal sphincter function score,recurrence rate,length of hospital stay,and hospitalization costs were recorded and analyzed Result:1.There was no statistically significant difference between the two groups in terms of gender and age(P>0.05),and the baseline characteristics were comparable.2.In terms of postoperative pain score(at 3 and 7 days after surgery),wound healing time,postoperative scar area,anal sphincter function score(at 1 month after surgery),and anorectal manometry indices(at 1 month after surgery),the observation group was superior to the control group,and the differences were statistically significant(P<0.05).3.There was no statistically significant difference between the two groups in terms of operation time,intraoperative bleeding volume,postoperative pain score(at 1and 14 days after surgery)and anal sphincter function score(at 7 days and 3 months after surgery),anorectal manometry indices(at 3 months after surgery),length of hospital stay,and hospitalization costs(P>0.05).4.The effective rate was 100% in both groups,and there was no statistically significant difference between the two groups.Conclusion:Both the improved retained anal sphincter arc-shaped bridging drainage and the traditional radiating multi-incision drainage technique are effective in the treatment of multiple-cavity anal fistulas.However,the improved retained anal sphincter arc-shaped bridging drainage is superior to the traditional technique in terms of wound healing time,postoperative scar area,postoperative pain,and short-term anal function.Therefore,it is recommended for further clinical application and promotion.
