The aim of this retrospective study was to evaluate the rate of recurrence and incontinence after the treatment of fistulae or fistulous abscesses by using the staged drainage seton method.
According to the condition, a drainage seton alone or a drainage seton combined with internal opening (IO) closure and relocation of the seton was used. After a period of time, the seton was changed with 3-0 nylon; then, after another period of time, the authors terminated the treatment by removing the 3-0 nylon. Telephone interviews were used for follow-up. The following were evaluated: the relationship between the type of fistula and recurrence; the relationship between the type of fistula and the period of treatment; the relationship between the recurrence and presence of abscess; the relationship between IO closure and recurrence; the relationship between the period of seton change and recurrence; reported continence for flatus, liquid stool, and solid stool.
The recurrence rate of fistulae or suppuration was 6.5%, but for cases of horseshoe extension, the recurrence rate was 57.1%. The rate of recurrence was related to the type of fistula (P = 0.001). Incontinence developed in 3.8% of the cases. No statistically significant relationship was found between the rate of recurrence and the presence of an abscess or between the closure of the IO and the period of seton change or removal.
In the treatment of anal fistulae or fistulous abscesses, the use of a staged drainage seton can reduce the rate of recurrence and incontinence.

Many kinds of substances are produced on vascular endothelial activation. The aim of this study is to confirm an increase in Endothelin-1 (ET-1), the most potent vasoconstrictor, which is produced by endothelial activation, in patients with chronic anal fissure and to infer the relationship between ET-1 and anal fissure chronicity.
The study groups are divided into three different groups with 30 subjects each. Group 1 is comprised of healthy volunteers, group 2 of chronic anal fissure patients, and Group 3 of patients with higher than 3rd degree hemorrhoids. Blood samples were taken to measure the ET-1 levels in subject's serum and to compare the results with those for the control groups.
Among the 90 subjects, 38 were male, and 52 were female. The average age was 36.8. The average ET-1 level marked 1.47 ± 0.78 pg/mL for male subjects and 1.16 ± 0.47 pg/mL for female subjects (P = 0.02). The average ET-1 level in the patient groups is as follow: 1.21 ± 0.44 pg/mL in group 1, 1.46 ± 0.83 pg/mL in group 2, and 1.20 ± 0.56 pg/mL in group 3 (P = 0.14).
Group 2, the chronic anal fissure patient group, showed a higher ET-1 level than groups 1 and 3, the control group and the hemorrhoid patient group, but this difference had no statistical significance.
