The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently em-ployed. However, at the moment, none of these tech-niques appear superior to the others in terms of healing rate. Surgery is always indicated to treat symptomatic, simple, low intersphincteric fistulas refractory to medi-cal therapy and those causing disabling symptoms. Ut-most attention should be paid to correcting the balance between eradication of the fistula and the preservationof fecal continence.展开更多

In order to answer this apparently simple question,we reviewed our clinical and surgical cases and most important relevant literature to find a rational and scientific answer.It would appear that whatever method you adopt in fistula management,there is a price to pay regarding either rate of recurrence (higher with conservative methods) or impairment of continence (higher with traditional surgery).Since,at the moment,reliable data to identify a treatment as a gold standard in the management of anal fistulas are lacking,the correct approach to this condition must consider all the anatomic and clinicopathological aspects of the disease;this knowledge joined to an eclectic attitude of the surgeon,who should be familiar with different types of treatment,is the only guarantee for a satisfactory treatment.As a conclusion,it is worthwhile to remember that adequate initial treatment significantly reduces recurrence,which,when it occurs,is usually due to failure to recognise the tract and primary opening at the initial operation.展开更多
