Seton in high anal fistula.

The use of seton still remains a reasonably valid option for its simplicity and optimal results in treating high anal fistulae. Ours was a single-centre retrospective study on patients with supra-sphincteric and transsphincteric types of high anal fistula, using the 'kharsutra' as seton. The first group were treated with a seton alone, while the second with a seton and partial fistulotomy. Results were similar and quite acceptable in both groups.
