[New approaches to the treatment of a ligature fistulas].

Original method of treatment of a ligature fistulas was proposed, using the ligature taking out via fistular passway or doing the cutaneous cutting under continuous ultrasonographic control. The efficacy and safety of the method, comparing with existing methods (probing "blindly" and excision of the fistula), was estimated. Original method owes advantage of possibility to visualize the ligatures and instruments on all stages of the intervention, small need in anesthesia, good medical-statistical indices. The method proposed constitute a clinically beneficial intervention and more effective one.
