A prospective study of a policy of selective immediate fistulotomy in the management of acute primary anal abscesses was performed. Eighty-nine patients (74%) underwent simple drainage only, as no internal openings were found during drainage of pus (group A). Thirty-one patients (26%) had drainage of pus and immediate fistulotomy (group B). Follow up for groups A and B occurred at a median of 122 weeks (104-136 weeks) and 121 weeks (104-136 weeks), respectively. No patient in group A had residual problems with anal continence whilst two patients (6.5%) from group B had minor anal incontinence following the initial procedure (p = 0.07). Ten patients from group A (11%) and four patients from group B (13%) developed recurrent anal sepsis. The overall rate of recurrent sepsis was 11.7%. In those patients who had incision and drainage alone, 90% of those who developed a recurrence and 71% of those who did not develop a recurrence grew gut-associated organisms from pus obtained during the initial drainage of the acute abscess, giving a positive predictive value for recurrence of 13.8% for a culture of gut-associated organisms. The positive predictive value for recurrent sepsis for both groups taken together for a culture of gut-associated organisms was 28.2%. Patients with acute primary anal abscess should be treated with simple drainage.

Fistula in ano is a very common presentation to colorectal clinic. Embarrassment due to the symptoms makes accurate estimations of incidence difficult. It is estimated that up to 40% of peri-anal abscess will be accompanied by or preceded by a fistula. Fistulae can be classified into simple fistulae that involve no or minimal sphincter muscle and complex, which involve significant amounts of the anal sphincter muscle, possibly with multiple tracts. For complex fistulae a seton suture is usually placed through the tract and out through the anus to form a loop allowing pockets of sepsis to drain internally and externally and a mature tract of fibrous tissue to develop. Following this period definitive fistula treatment is considered. This can involve a number of procedures that have tremendously varied success rates in the literature. The first stage of surgical treatment is often a core fistulectomy, which entails surgical removal of the tract. This may be followed by insertion of fibrin glue, a collagen plug or formation of a rotation skin flap from surrounding tissue in order to close the resultant tissue defect. All current treatments have a significant failure rate. If this wound breaks down the surgery can leave a large painful peri-anal wound that can lead to ongoing fistulation. Should this occur resiting of the seton will be required with the patient only getting back to square one after months of healing around the seton. In addition removing cores of fibrous tissue passing through the sphincter can threaten the sphincter function resulting in impaired continence. Having seen radiofrequency ablation used to close varicose veins the authors propose that one could use similar techniques to close a fibrous tract matured with a seton in order to close a fistula. The authors propose that a short length radiofrequency catheter could be used to treat fistula in ano. This would in theory be less painful with less tissue destruction. In addition there would be no necessity for extensive incisions. As the energy penetration can be controlled the procedure will be safe even if it fails, without causing a large wound or tissue necrosis. All other treatment options will still be available.
