The only available treatment for anal fistula is surgical. Treatment with antibiotics has temporary results and the problem may recur in a more extensive way. A preoperative mapping of anal fistula with endoanal ultrasound contributes to a better understanding of fistula\u2019s anatomy.<\/p>\n\n\n\n
The best treatment for simple low fistulas is lay-open. That is the tissue covering fistula is divided and the fistula tract comes to the surface (simple fistulotomy). The secondary healing of the wound is easy and pain is minimal.<\/p>\n\n\n\n
If the ramifications or the anal opening are not treated, fistulas reappear.<\/p>\n\n\n\n
If a significant part of anal sphincter is divided, fecal incontinence may be a major complication of fistulotomy.<\/p>\n\n\n\n
In the case that anal fistula runs through a significant part of anal sphincter, then they are labelled as high or intersphincteric anal fistula.<\/p>\n\n\n\n
Specialized surgical techniques for treatment of high anal fistulas.<\/strong><\/p>\n\n\n\n The successful treatment of high anal fistulas require special surgical techniques because sphincter damage and fecal incontinence may result from the simple lay-open technique in this category of anal fistulas.<\/p>\n\n\n\n The best known techniques for the management of anal fistulas are the following<\/strong><\/p>\n\n\n\n
