This study aims to investigate whether specialized red-blue light irradiation facilitates faster postoperative recovery and reduces complication rates in patients following perianal abscess surgery. 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.

Wound healing time
Timeframe: Measurements were taken over a time frame of 24 hours postoperatively to complete epithelialisation.
