Clinical effectiveness and safety evaluation of modified ligation of intersphincteric fistula tract for complex anal fistulae
Objective To explore the clinical effectiveness and safety evaluation of modified ligation of intersphincteric fistula tract(LIFT)for complex anal fistulae.Methods 66 patients with complex anal fistula were divided into a control group and an observation group by random number table method,with 33 cases in each group.The control group was given conventional LIFT,and the observation group was given modified LIFT.Comparison was made on surgical related indicators,short-term efficacy,anal canal resting pressure and anal canal systolic pressure,and complications between the two groups.Results There were no significant differences in operation time,intraoperative blood loss,postoperative wound healing time,postoperative pain duration and postoperative hospital stay between the two groups(P>0.05).The total effective rate of the observation group was 93.94%,which was significantly higher than 75.76%of the control group(P<0.05).At 3 months after surgery,the anal canal resting pressure and anal canal systolic pressure of the control group were(55.63±8.24)and(124.32±19.35)mm Hg(1 mm Hg=0.133 kPa),and those of the observation group were(55.72±8.56)and(124.52±19.58)mm Hg;there was no significant difference in comparison(P>0.05).The complication rate of the observation group was 15.15%,which was significantly lower than 39.39%of the control group(P<0.05).Conclusion Modified LIFT has more significant clinical efficacy and higher safety for patients with complex anal fistula,and will not affect anal function,which is conducive to the early recovery of patients,and is worth adopting and promoting.
