Abstract:Abstract: Objective To investigate the clinical effect of Mayinglong Hemorrhoids Suppository-assisted with operation in the treatment of complex anal fistula. Methods Totally 110 patients with complex anal fistula were chosen and randomly divided into control group and observation group, each had 55 cases. The patients in the control group were treated with free flap suture occlusion surgery, those in the observation group were added with Mayinglong Hemorrhoids Suppository. The curative effect, influencing factors and the occurrence of postoperative complications were compared between the two groups. Results The healing rate of the observation group was higher than that of the control group, and the incidences of complications were lower than those of the control group (P < 0.05). The wound healing time and pain persistent time of the observation group were significantly shorter than those of the control group (P < 0.05). The anal function scores, the maximum systolic pressure of anal canal, the longest contraction time of anal canal, the urinary retention index, and anal resting pressure of anal canal after treatment in the observation group were significantly better than those in the control group (P < 0.05). Conclusions Mayinglong Hemorrhoids Suppository-assisted operation can effectively improve the treatment effect and the prognosis in the treatment of complex anal fistula.
