High ligation of the anal fistula tract by lateral approach: A prospective cohort study on a modification of the ligation of the intersphincteric fistula tract (LIFT) technique.

Background: Ligation of the intersphincteric fistula tract (LIFT) is a sphincter-preserving operation for anal fistulas. Although it has advantages in preserving continence after surgery, it is difficult to perform owing to the narrow field of view. We performed a modified surgical procedure based on the LIFT to overcome these drawbacks.

Comparison of skin incisions used for open lateral internal sphincterotomies--radial versus circumferential incisions: a retrospective cohort study.

Introduction: Lateral internal sphincterotomy (LIS) is a safe and effective surgical treatment, commonly used in patients with chronic anal fissures (CAFs). Although LIS is a simple surgical technique, it may cause several complications. Open LIS is usually performed through an incision made in the intersphincteric groove; radial or circumferential incisions, used according to the surgeon's preference.

The use of a staged drainage seton for the treatment of anal fistulae or fistulous abscesses.

Purpose: 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.

Methods: 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.

Is There Any Relationship between the Chronicity of Chronic Anal Fissure and Endothelin-1?

Purpose: 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.

Methods: The study groups are divided into three different groups with 30 subjects each.

Risk factors for anastomotic leakage after laparoscopic rectal resection.

Purpose: The anastomotic leakage rate after rectal resection has been reported to be approximately 2.5-21 percent, but most results were associated with open surgery. The aim of this study was to identify risk factors and their relationship to the experience of the surgeon for anastomotic leakage after laparoscopic rectal resection.
