Summary

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.

Conditions

  • Chronic Anal Fissure

Interventions

PROCEDURE

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 The internal anal sphincter was then dissected and a segment withdrawn with a pair of artery forces and divided with diathermy to the level of the dentate line.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.

PROCEDURE

GroupII: V-Y advancement flap

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.

PROCEDURE

GroupIII: Tailored LIS 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 The internal anal sphincter was then dissected and a segment withdrawn with a pair of artery forces and divided with diathermy, the extent of sphincterotomy was done to be more or less equal to the length of the fissure.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.
