About this study

Official title: Effect of Red and Blue Light Irradiation on Wound Healing After Hemorrhoid Surgery: A Single - Center Prospective Open - Label Randomized Clinical Trial

The subjects of this study were patients who took mixed haemorrhoidectomy during the period of December 2024 - December 2025 . The haemorrhoidectomy patients were randomly divided into routine group, red light group and red and blue light group, and were given different ways of trauma care, and the number of cases in each group was 105 , with a total of 305 cases. Observe the difference between red and blue light irradiation and routine care on the healing time of postoperative trauma and postoperative complications after haemorrhoidectomy, and evaluate the patients' quality of life and satisfaction with treatment under both red light irradiation and routine care.

Read the detailed description

The subjects of this study were patients who took mixed haemorrhoidectomy during the period of December 2024 - December 2025 . The diagnostic criteria were haemorrhoidal disease diagnosed as degree III-IV according to Goligher's classification. Inclusion criteria were 18 years < age < 75 years; diagnosis of haemorrhoids; internal haemorrhoid ligation + external haemorrhoidectomy. Exclusion criteria were patients with psychiatric disorders; patients with chronic diseases such as diabetes mellitus, hypertension and coronary artery disease; patients who underwent other treatments in addition to haemorrhoidectomy such as haemorrhoidal radiofrequency ablation/ sclerotherapy; patients who were unable to cooperate with the follow-up; and patients with perianal abscess, anal fissure, anal fistulae, and anorectal papillae hypertrophy. The haemorrhoidectomy patients were randomly divided into the conventional group, the red light group and the red and blue light group, and were given different ways of trauma care, and the number of cases in each group was 105 , with a total of 305 cases. The control group was given routine potassium permanganate sitz bath and routine care after internal haemorrhoid ligation + external haemorrhoidectomy to encourage patients to carry out functional exercise in moderation, mainly for anal lifting, buttock lifting and abdominal massage, etc.; the red light group was based on the control group, using red light irradiation for traumatic treatment; the red and blue light group was based on the control group, using red and blue light irradiation for traumatic treatment. Observe the difference between red and blue light irradiation and routine care on the healing time of postoperative trauma and postoperative complications after haemorrhoid surgery, and evaluate the patients' quality of life and satisfaction with treatment under both red light irradiation and routine care. Specific research content is to collect the postoperative data of the three groups of patients, including the recording of surgery-related pain scores, respectively, before the red light intervention and after the intervention of 1 d, 2 d, 3 d, 5 d, 7 d using visual analogue scoring (VAS) to assess the intensity of the patient's pain; the recording of the length of hospital stay; the recording of the degree of oedema of the anal verge were assessed before the red light intervention and after the intervention of 1 d, 2 d, 3 d, 5 d, 7 d, respectively, 0 Score 0: no oedema or slight oedema on the wound, but no impact on life. Score 2: oedema is present in only one area of the wound and is less than 1 cm in diameter, affecting daily activities. 4 points: multiple oedemas with a diameter of 1-2 cm, affecting daily activities. 6 points: multiple oedemas with a diameter of more than 2 cm, seriously affecting daily activities; follow up on the time to complete healing of the wound, quality of life scores, and the patient's satisfaction with the treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Red light exposureDevice

    Patients in the red light group received red light therapy concurrently with standard care.

  • Red-blue light exposureDevice

    Patients in the red and blue light group received combined red and blue light therapy concurrently with standard care.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Wound healing time

    Defined as 100% re-epithelialization assessed by blinded evaluator

    Measured: Daily from Day 1 until complete epithelialization (max 28 days post-op)

Secondary outcomes (4)
  1. Postoperative pain intensity (VAS score)

    Assessed at rest and during defecation

    Measured: Baseline, Day 1, 2, 3, 5, 7, and Day 14±2

  2. Perianal edema severity (0-6 scale)

    Evaluated by trained research nurses

    Measured: Day 1, 2, 3, 5, 7, and Day 14±2

  3. Length of hospital stay

    Measured in hours with standardized discharge criteria

    Measured: From surgery end to discharge (up to 7 days)

  4. Complication incidence

    Classified by Clavien-Dindo grading system

    Measured: Within 30 days postoperatively

What does the primary outcome measure?

Wound healing time (time frame: Daily from Day 1 until complete epithelialization (max 28 days post-op)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
