Efficacy Analysis of Modified Transanal Mucosal Flap Displacement in Treatment of Rectal Submucous Fistula
Objective To investigate the clinical efficacy of modified endorectal advancement flap(ER-AF)in the treatment of rectal submucous fistula.Methods A total of 62 patients with rectal submucous fistula admitted to our hospital from June 2021 to June 2023 were randomly divided into observation group and control group,with 31 cases in each group.The observation group was treated with modified ERAF,while the control group was treated with traditional incision and thread-drawing surgery.Postoperative pain,first defecation time,intraoperative blood loss and infection were compared between the two groups.Results There were no significant differences in the first postoperative defecation time,intraoperative blood loss,operation time and incidence of urinary retention between the two groups(P>0.05).The one-time cure rate of the observation group was higher than that of the control group(P<0.05).The pain VAS scores of the observation group on the 1st,7th and 15th day after surgery were lower than those of the control group(P<0.05).The incidence of postoperative bleeding,infection,anal incontinence and recurrence rate of the observation group were lower than those of the control group(P<0.05).The wound healing time was(23.45±3.56)d in the observation group,which was shorter than(36.28±5.58)d in the control group(P<0.05).Conclusion Both modified ERAF and traditional incision and thread-drawing surgery are effective in the treatment of submucous fistula,but modified ERAF can relieve postoperative pain,reduce postoperative bleeding and incidence of anal incontinence,shorten wound healing time,and improve patients'quality of life.
