Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators compared conventional lateral internal sphincterotomy (CLIS), V-Y anal flap, and combined tailored lateral internal sphincterotomy with V-Y anal flap (TLIS with V-YF) in a randomized prospective study in patients undergoing treatment for chronic anal fissure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Group I: Conventional Lateral internal sphincterotomy:

LIS was performed in the lithotomy position by a standard open technique, briefly; a 5-mm incision was made into the perianal skin along the intersphinteric groove. The internal anal sphincter was then dissected and a segment withdrawn with a pair of artery forces and divided with diathermy to the level of the dentate line. Figures 5, 6, 7 and 8 illustrate the procedure.

GroupII: V-Y advancement flap:

The V-Y advancement flap was performed by making a V-shaped incision from the edges of the fissure extending about 4 cm from the anal verge and away from the midline. The V-shaped flap formed of skin and subcutaneous fat was mobilized sufficiently to allow advancement into the anal canal to cover the fissure defect. Care was taken to preserve enough pedicles to ensure adequate blood supply. The base of flap was sutured to the lower anal mucosa with interrupted 000 Vicryl Rapide. Figures 1, 2, 3 and 4 illustrate the procedure.

GroupIII: Tailored lateral internal sphincterotomy with V-Y advancement flap:

Tailored lateral sphincterotomy was performed in the lithotomy position by a standard open technique, briefly; a 5-mm incision was made into the perianal skin along the intersphinteric groove. The internal anal sphincter was then dissected and a segment withdrawn with a pair of artery forces and divided with diathermy, the extent of sphincterotomy was done to be more or less equal to the length of the fissure. Then the V-Y advancement flap was performed All assessments were conducted by investigators who were blinded to the experimental condition. The primary outcome was complete healing (complete epithelization scare or no sign of fissure, healing was considered to be delayed if the wound had not completely healed by 6 weeks after the procedure). Secondary outcomes were operative time, length of hospital stay, anal incontinence (determined by Pescatori scoring system (32), time of relieve of pain, postoperative anal manometery, complications (eccyhmosis, haematoma, infection, disruption of flap, flap necrosis), persistent symptoms, patients satisfaction ( assessed on a visual analogue scale VAS), recurrence rate and quality of life.

Quality of life was assessed using the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch and coworkers

TLIS with VY anoplasty

Tailored lateral sphincterotomy was performed in the lithotomy position by a standard open technique, briefly; a 5-mm incision was made into the perianal skin along the intersphinteric groove. The internal anal sphincter was then dissected and a segment withdrawn with a pair of artery forces and divided with diathermy, the extent of sphincterotomy was done to be more or less equal to the length of the fissure. Then the V-Y advancement flap was performed.
