BACKGROUND:Treatment methods for high anal fistula include fistula removal, incision and thread drawing, selective mucosal flap displacement, fibrin glue closure, fistula liagtion between sphincter, most of which show many advantages, including long-term healing, a low success rate, high recurrence rate, and high postoperative complication rate.
OBJECTIVE:To observe the clinical effect of acelular extracelular matrix in the treatment of high anal fistula, and to explore a minimaly invasive treatment for high anal fistula.
METHODS: Totaly 100 cases of high anal fistula were randomly divided into treatment group and control group, 50 cases in each group. Treatment group were treated with alogenic acelular extracelular matrix, and control group were treated with traditional low incision with high thread-drawing. Then, we observed and compared the operation time, bleeding volume, postoperative pain score (visual analog scale score), postoperative pain
duration, anal incontinence severity score (Wexner score), wound healing time, one-stage success rate, cure rate, recurrence rate.
RESULTS AND CONCLUSION: Compared with the control group, the treatment group showed lower scores in the operation time, bleeding volume, wound healing time, visual analog scale score, postoperative pain duration, and anal incontinence severity score (P < 0.05), but higher scores in one-stage success rate and cure rate (P < 0.05). There was no difference in the recurrence rate between the two groups. These findings indicate that the alogenic acelular extracelular matrix for treatment of high anal fistula exhibits smal trauma, quick recovery,
short course of treatment, high cure rate and has no damage to the anal function and appearance.

Objective To study the image examination of renal injuries and discuss renal explorative indications so as to spare the kidney or nephron as much as possible and improve curative rate of diagnosis and treatment. Methods An analysis was done on 286 cases that included 231 cases with close injury, 54 with open injuries, one with iatrogenic injury and 91 with combined injuries. Of all, 212 cases were examined by B-ultrasonography, 163 by CT and 132 by intravenous urography(IVU) and 6 by digital subtraction angiography(DSA); 202 cases were treated with conservative treatment and 84 with operation. Results The diagnostic positive rates of IVU, B-ultrasonography and CT were 67.4%, 72.2% and 87.7%, respectively. Among the operation cases, 42 cases were treated by renal repair, 12 by partial nephrectomy and 30 by nephrectomy. The operation rate was 29.4% and the nephrectomy rate 35.5%. Interventional treatment of the kidney was carried out in three cases. Conclusions For renal injury cases, the first and most important step is to evaluate the injury condition so as to correctly determine whether an operation exploration is needed. The injury conditions and severity are mainly determined by the image examinations that change according to injury cause, injury type and clinical symptoms. Renal exploration or not, and the operation time exert great influence on renal reservation rate and complication rate.
