Clinical effect of incision debridement and drainage combined with thread-ligating therapy in the treatment of patients with high anal fistulae
Objective To observe the clinical efficacy of incision debridement and drainage combined with thread-ligating therapy in the treatment of patients with high anal fistulae(HAF),and its influence of anorectal function of the patients.Methods 66 HAF patients were divided into a control group and an observation group according to random number table method,with 33 cases in each group.The control group was treated with incision and thread-ligating therapy,and the observation group was treated with incision debridement and drainage on the basis of the control group.The postoperative recovery indexes,anorectal dynamics indexes,efficacy and complications were compared between the two groups.Results The wound healing time and hospitalization time of the observation group were(21.45±2.36)d and(16.42±1.45)d,which were shorter than(27.16±2.42)d and(22.61±1.61)d of the control group;the observation group had smaller scar area of(3.53±0.22)cm2 than(5.16±0.35)cm2 of the control group(P<0.05).In the observation group,the anal canal resting pressure,rectal canal resting pressure and maximum anal systolic pressure 1 week after operation were not significantly different from those before operation(P>0.05).In the control group,the anal canal resting pressure,rectal canal resting pressure and maximum anal systolic pressure 1 week after operation were obviously lower than those before operation(P<0.05).The anal canal resting pressure,rectal canal resting pressure and maximum anal systolic pressure 1 week after operation in the observation group were higher than those in the control group(P<0.05).The observation group had total effective rate of 90.91%,which was higher than 69.70%in the control group(P<0.05).The observation group had complication rate of 6.06%,which was lower than 24.24%in the control group(P<0.05).Conclusion For HAF patients,the combination of incision debridement and drainage on the basis of thread-ligating therapy is conducive to relieve pain,promote postoperative recovery,and has a certain protective effect on intestinal function,with fewer complications and reliable efficacy.
