Sliding skin grafts in the treatment of anal fissures:
Excision of a chronic fissure in ano and covering of the defect with a sliding-flap broad-based skin graft offers the advantages of: 1) decreased postoperative pain; 2) decreased postoperative wound care, in both hospital and office; 3) decreased incidence of postoperative complications (recurrent anal fissure and stenosis are rare, the diameter of the anus is actually increased and is our procedure of choice for anal stenosis); 4) primaryvs. secondary wound healing,i.e., a) healing more rapid, b) decreased scar and resultant deformity, c) decreased postoperative inflammatory response and infection; 5) the increased operative time is not harmful to the patient under caudal or epidural anesthesia.
