A total of 222 eligible patients were randomly allocated equally into three groups (74 per group):①Routine Care Group: Standard wound care including cleansing and dressing changes；②Red Light Therapy Group: Routine care plus red light phototherapy；③Combined Red-Blue Light Therapy Group: Routine care plus concurrent red and blue light phototherapy.Wound healing time and incidence of complications were compared to assess postoperative recovery across interventions. The primary hypothesis posits that adjunctive phototherapy-particularly combined red-blue light irradiation-will significantly enhance wound healing, reduce edema and pain, and decrease complication rates (e.g.bleeding, urinary retention) compared to routine care alone.",[70],"Perianal Abscess",[72,73,74,75],"perianal abscess","red light phototherapy","red and blue light phototherapy","wound healing","NOT_YET_RECRUITING","2025-09-01",{"date":79,"type":80},"2025-09-04","ACTUAL",{"date":82,"type":64},"2025-09-15",{"date":84,"type":64},"2026-09-30",{"name":5,"class":6},1]
