Official title

Effect of Red and Blue Light Irradiation on Postoperative Wound Healing in Perianal Abscess: a Single-center Prospective Open-label Randomized Clinical Trial

Overview

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.

Interventions

  • Device Red light exposure
    Patients in the red light group received red light therapy concurrently with standard care.
  • Device Red-blue light exposure
    Patients in the red and blue light group received combined red and blue light therapy concurrently with standard care。

Primary outcome measures

  • Wound healing time [Time frame: Measurements were taken over a time frame of 24 hours postoperatively to complete epithelialisation.]
Secondary outcome measures (5)
  • Postoperative pain intensity [Time frame: Baseline, Day 1, 3, 5, 7, and Day 14±2]
  • Peripheral tissue edema(Grade 0-3) [Time frame: Day 1, 3, 5, 7, and Day 14±2]
  • Assessment of Granulation Tissue in Wound Bed [Time frame: Day 1, 3, 5, 7, and Day 14±2]
  • Length of hospital stay [Time frame: From surgery end to discharge (up to 7 days)]
  • Complication incidence [Time frame: Within 30 days postoperatively]

Eligibility criteria

Inclusion criteria

  • Aged between 18 and 75 years;
  • Clinical diagnosis of perianal abscess;
