S. Walfisch et al., DOUBLE SETON - A NEW MODIFIED APPROACH TO HIGH TRANSSPHINCTERIC ANAL FISTULA, Diseases of the colon & rectum, 40(6), 1997, pp. 731-732

been recognized and treated for many years, there is still a lack of c
onsensus among colorectal surgeons as to the optimum surgical approach
. We have devised a modification of the seton technique, which we used
in 23 patients without complications or recurrence.
